The user plane network element in the 5G core network may use DPDK acceleration, and in the prior art, the user plane network element based on DPDK does not support the IPv6 protocol stack yet. The application supports IPv6 protocol stack on the user plane network element based on DPDK, namely IPv6 data packet is forwarded at high speed on the user plane network element.
In one embodiment, as shown in fig. 2, there is provided an IPv6 packet processing method applied to a DPDK-based user plane element in a 5G core network, and the method is applied to a server 104 in fig. 1 for illustration, and includes the following steps:
s202, IPv6 data packets from the user equipment are received through a first interface of the user plane network element.
The user plane Network element refers to a user plane function (UPF, user Plane Function) in a 5G Core Network (5G Core Network), where the UPF is mainly responsible for routing and forwarding related functions of a data packet of the 5G Core Network. The first interface may refer to an interface between the UPF and the 5G base station and belongs to the UPF side. The user equipment may be referred to as a terminal. An IPv6 data packet may refer to a data packet that satisfies an IPv6 related protocol.
As shown in fig. 3a, an application scenario diagram of an IPv6 packet processing method is shown; in the whole IPv6 packet processing process, interaction between a user equipment, a 5G base station, a user plane network element, a session management network element, and a data network is mainly involved, where the session management network element may refer to SMF (Session Management function ) in a 5G core network, and the data network may refer to an external data network of the 5G core network. Where N3 may represent the interface between the UPF and the 5G base station, i.e. N3 comprises the first interface and the interface belonging to the 5G base station side. N6 may represent an interface between the UPF and the data network, the interface belonging to the UPF side in N6 being the second interface. The application supports IPv6 protocol stack on user plane network element based on DPDK, mainly relates to interfaces on user plane network element as first interface and second interface, that is IPv6 data packet can be forwarded at high speed on first interface and second interface of user plane network element.
Specifically, the user equipment may send an IPv6 data packet, receive the IPv6 data packet via the 5G base station, forward the IPv6 data packet, and the server receives the IPv6 data packet from the 5G base station through the first interface of the user plane network element.
In one embodiment, after the 5G base station receives the IPv6 data packet, the 5G base station may add the IP address and port information of the first interface of the UPF to the IPv6 data packet, so that the IPv6 data packet is smoothly forwarded to the first interface of the UPF. Wherein the IP address includes an IPv4 address and an IPv6 address, for example, the IP address may be "172.16.0.203". The port information may refer to a port number corresponding to the interface, for example, the port information may be "port:2003".
S204, determining the target IPv6 address in the IPv6 data packet.
The target IPv6 address may refer to an IPv6 address of a target node to which the IPv6 packet eventually arrives. The target node may be a respective server of the operator or another user equipment or the like.
Specifically, the user plane network element in the server may determine a processing field in the IPv6 data packet according to a preset IPv6 structure; decoding the IPv6 data packet based on the processing field to obtain a decoded IPv6 data packet; and determining the target IPv6 address in the decoded IPv6 data packet. And re-encapsulating the decoded IPv6 data packet according to the target physical address, and forwarding the encapsulated IPv6 data packet through a second interface of the user plane network element.
Wherein, the preset IPv6 structure may be used to determine a processing field in the IPv6 data packet, and the preset IPv6 structure may include a header structure, a port structure, and a data structure, etc., and the header structure may be used to determine a processing field in header information of the IPv6 data packet. The port structure may be used to determine a processing field in the port information of the IPv6 data packet. The data structure may be used to determine a processing field in data (data) of an IPv6 data packet. The preset IPv6 structure body can determine the processing field in the IPv6 data packet, namely after determining the processing field in the IPv6 data packet, the processing field in the IPv6 data packet is subjected to encoding and decoding processing, the operations of filling default values or not judging processing or merging other items are uniformly adopted for other fields, and the default values in the filling default values can be 0 or 255 and the like, so that the efficiency of encoding and decoding the IPv6 data packet is effectively improved by adopting the preset IPv6 structure body. The processing field may refer to a field for codec processing in an IPv6 packet. The target physical address may refer to a MAC (MEDIA ACCESS Control) address of the target node at the data link layer, e.g., intelCor _b1:1a:ca (90:e2:ba:b1:1a:ca).
For example, when the predetermined IPv6 structure is a header structure, the header structure may be
When header information in the IPv6 packet is as follows,
The case where the head structure corresponds to a flag (tag) in the head information may be VtcFlow corresponds to er16.. TRAFFIC CLASS; payloadLen corresponds to Payload Length; proto corresponds to Next Header; hopLimits corresponds to Hop Limit; srcAddr corresponds to Source Address; dstAddr corresponds to Destination Address. Can be expressed as:
The processing field in the header information of the IPv6 data packet is that er16....＝Version:6、Traffic Class:0x00、Payload Length:72、Next Header:UDP(17)、Hop Limit:64、Source Address:2001::23、Destination Address:2001::4.
S206, inquiring whether to store the target physical address corresponding to the target IPv6 address.
Specifically, the user plane network element in the server may query whether the neighbor table stores the target physical address corresponding to the target IPv6 address.
The neighbor table may be used to store a physical address (MAC address of the data link layer) corresponding to the IP address, for example, the neighbor table may store a physical address corresponding to the IPv6 address.
S208, if not, generating a target multicast physical address based on the target IPv6 address, and acquiring the target physical address according to the target multicast physical address.
The target multicast physical address may be used to determine a multicast corresponding to the target IPv6 address.
In one embodiment, generating the target multicast physical address based on the target IPv6 address includes a user plane network element in the server generating the target multicast IPv6 address based on the target IPv6 address, and generating the target multicast physical address based on the target multicast IPv6 address.
The target multicast IPv6 address may be used to determine a multicast corresponding to the target IPv6 address.
In one embodiment, generating the target multicast physical address based on the target IPv6 address further includes obtaining a multicast IPv6 address format and a multicast physical address format; intercepting the target IPv6 address based on the multicast IPv6 address format to obtain an intercepted target IPv6 address, and replacing the multicast IPv6 address format based on the intercepted target IPv6 address to obtain a target multicast IPv6 address; intercepting the target multicast IPv6 address based on the multicast physical address format to obtain an intercepted target multicast IPv6 address, and replacing the multicast physical address format based on the intercepted target multicast IPv6 address to obtain the target multicast physical address.
Wherein, the multicast IPv6 address format may refer to a representation of a multicast IPv6 address. The multicast physical address format may refer to a representation of a multicast physical address.
For example, if the target IPv6 address is 2001:0000:0000:0000:0000:0000:0023, which is 2001:23, the multicast IPv6 address format is FF 02:0000:0000:0001:ffxx:xx, the last six bits "000023" of the target IPv6 address can be taken to replace the last six bits xx:xx in the multicast IPv6 address format, which is the generated target multicast IPv6 address is "FF 02:0000:0000:0000:0000:0000:0001:ff00:0023", and then the last six bits "000023" of the target multicast IPv6 address can be taken to replace the last six bits "xx.xx.xx" in the multicast physical address format according to the multicast physical address format of 33:33:ff:xx:xx:xx, so as to obtain the target multicast physical address of "33:33:ff:00:00:0023".
In one embodiment, generating the target multicast physical address based on the target IPv6 address further includes obtaining a multicast physical address format; intercepting the target IPv6 address based on the multicast physical address format to obtain an intercepted target IPv6 address, and replacing the multicast physical address format based on the intercepted target IPv6 address to obtain the target multicast physical address.
In one embodiment, the obtaining the target physical address according to the target multicast physical address includes sending a neighbor solicitation (Neighbor Solicitation, NS) message to a corresponding multicast according to the target multicast physical address by a user plane network element in the server, comparing the neighbor solicitation (Neighbor Solicitation, NS) message with the target multicast physical address stored by the target node after the target node receives the NS message, and generating a corresponding neighbor advertisement (Neighbor Advertisement, NA) message according to the corresponding target physical address when the target multicast physical address stored by the target node is consistent with the target multicast physical address in the NS message. And the target node returns the NA message, and a user plane network element in the server acquires a target physical address in the NA message.
For example, fig. 3b is an application scenario diagram of another IPv6 packet processing method; it can be seen that when IPv6 packets are transmitted between the 5G base station, the user plane network element, and the data network, NS packets and NA packets can be used for addressing. The NS message and the NA message conform to neighbor discovery protocol (Neighbor Discovery Protocol, NDP), which is a base protocol in the IPv6 protocol system.
In one embodiment, after S208, the user plane network element in the server may store the obtained target physical address in the neighbor table in correspondence with the target IPv6 address. For example, the server may store the target physical address in the returned NA message in a neighbor table.
In one embodiment, if the target physical address corresponding to the target IPv6 address is stored, the user plane network element in the server may execute the steps of repackaging the IPv6 packet according to the target physical address, and forwarding the IPv6 packet obtained by the encapsulation through the second interface of the user plane network element.
S210, the IPv6 data packet is repackaged according to the target physical address, and the IPv6 data packet obtained through encapsulation is forwarded through a second interface of the user plane network element.
In one embodiment, repackaging the IPv6 packet according to the target physical address includes: the user plane network element in the server removes the IP address and the port information added by the last node in the IPv6 data packet to obtain a pre-forwarding IPv6 data packet; and replacing the destination physical address in the pre-forwarding IPv6 data packet with the destination physical address.
The pre-forwarding IPv6 data packet may refer to an IPv6 data packet after the user plane network element removes the IP address and port information added by the previous node, or an IPv6 data packet added with the IP address and port information of the next node.
For example, in connection with the application scenario of fig. 3a and fig. 3b, when an IPv6 data packet is sent from a ue to a 5G base station, the 5G base station adds an IP address and port information of a first interface of the ue to the IPv6 data packet and sends the IPv6 data packet to the ue, and after the ue receives the IPv6 data packet, removes the IP address and port information added by the 5G base station, and then sends the IPv6 data packet to a data network through a second interface of the ue.
When the IPv6 data packet is sent from the data network to the second interface of the user plane network element, the user plane network element adds the IP address and the port information of the 5G base station to the IPv6 data packet and sends the IPv6 data packet to the 5G base station, and after the 5G base station receives the IPv6 data packet, the IPv6 data packet is sent to the user equipment through the first interface of the user plane network element after the IP address and the port information added by the user plane network element are removed.
In one embodiment, after the IPv6 data packet is repackaged according to the target physical address, the user plane network element in the server may encode the encapsulated IPv6 data packet based on the processing field, to obtain an encoded IPv6 data packet; and forwarding the coded IPv6 data packet through a second interface of the user plane network element.
In one embodiment, a user plane network element in a server may receive an IPv6 data packet from a user equipment or another server (e.g., a server of an operator) via a second interface of the user plane network element; determining a target IPv6 address in an IPv6 data packet; inquiring whether to store a target physical address corresponding to the target IPv6 address; if not, generating a target multicast physical address based on the target IPv6 address, and acquiring the target physical address according to the target multicast physical address; and re-encapsulating the IPv6 data packet according to the target physical address, and forwarding the encapsulated IPv6 data packet through a first interface of the user plane network element.
In one embodiment, the user plane network element in the server may implement the qos rule corresponding to the IPv6 protocol, for example, the user plane network element may perform rule matching with the five-tuple (source IPv6 address, destination IPv6 address, source port, destination port, and direction) of IPv6 as a filtering condition.
In the above-mentioned IPv6 data packet processing method, an IPv6 data packet from a user equipment is received through a first interface of a user plane network element; determining a target IPv6 address in an IPv6 data packet; when the target physical address corresponding to the target IPv6 address is not stored, generating a target multicast physical address based on the target IPv6 address, and acquiring the target physical address according to the target multicast physical address; and re-encapsulating the IPv6 data packet according to the target physical address, and forwarding the encapsulated IPv6 data packet through a second interface of the user plane network element. The method and the device realize the purpose of determining and solving the problem that the high-speed forwarding of IPv6 data packets based on DPDK cannot be realized on UPF by utilizing the target physical address corresponding to the multicast fast target IPv6 address, and meet the requirement of supporting an IPv6 (Internet Protocol Version, 6 th edition of Internet protocol) protocol stack under the scene of high-speed forwarding of a 5G core network. Moreover, the physical address corresponding to the IPv6 address is stored by utilizing the proximity table, so that the efficiency of inquiring the target physical address is improved, and the preset IPv6 structure body efficiently screens the useful fields of the IPv6 data packet by determining the processing fields in the IPv6 data packet, so that when the IPv6 data packet is encoded and decoded, each field does not need to be judged and processed, the encoding and decoding efficiency of the IPv6 data packet is greatly improved, and the forwarding speed of the UPF on the IPv6 data packet is further improved.
In one embodiment, as shown in fig. 4, the step of obtaining an IPv6 prefix address includes:
s402, receiving a router request message sent by user equipment.
The routing request (Router Solicitation, RS) message may refer to a message for requesting to acquire an IPv6 prefix address.
Specifically, the user equipment sends an RS message to the 5G base station, after the 5G base station receives the RS message, the IPv6 address and port information of the first interface of the user plane network element are added to the RS message, the RS message is sent to the user plane network element in the server, and the user plane network element receives the RS message sent by the 5G base station.
In one embodiment, the IPv6 addresses of the first interface and the second interface of the user plane network element may be configured from a configuration file. The configuration file can be used for configuring the IP address of the corresponding interface of the user plane network element, and the configuration file is used for configuring the IP address, so that the configuration of the IP address is more convenient.
In one embodiment, before S402, fig. 5 is a schematic flow chart of acquiring an IPv6 suffix address; when the type of the session established by the user equipment is IPv6, the SMF sends an interface ID to the corresponding 5G base station of the user equipment, the 5G base station sends the interface ID to the user equipment, and the user equipment takes the interface ID as an IPv6 suffix address.
Wherein the IPv6 suffix address may refer to a posterior segment portion of the IPv6 address of the user equipment.
S404, the physical address of the session management network element in the 5G core network is obtained.
Specifically, the user plane network element in the server may query whether the neighbor table stores the physical address of the session management network element according to the IP address of the session management network element, and if the neighbor table stores the physical address of the session management network element, the physical address is used as the physical address of the session management network element in the 5G core network. If the physical address of the session management network element is not stored in the neighbor table, when the type of the IP address of the session management network element is an IPv6 address, generating a multicast physical address of the session management network element based on the IPv6 address of the session management network element, and acquiring the physical address of the session management network element according to the multicast physical address of the session management network element; when the type of the IP address of the session management network element is an IPv4 address, the physical address of the session management network element in the 5G core network may be obtained according to ARP (Address Resolution Protocol ).
S406, the router request message is forwarded to the session management network element according to the physical address of the session management network element, so that the session management network element returns the router advertisement message.
Among other things, a route advertisement (Router Advertisement, RA) message may refer to a message for returning an IPv6 prefix address. The IPv6 prefix address may refer to a front portion of an IPv6 address of the user equipment, and the Pv6 prefix address and the IPv6 suffix address may be spliced into a complete IPv6 address.
In one embodiment, after forwarding the router solicitation message to the session management network element, the session management network element generates an RA message corresponding to the RS message, where the RA message contains an IPv6 prefix address of the user equipment and an IPv6 address and port information of the user plane network element.
In one embodiment, before S406, the user plane network element in the server modifies the IPv6 address and port information added by the previous node, e.g., the 5G base station, to the IPv6 address and port information of the session management network element in the RS message.
S408, the router advertisement message returned by the session management network element is forwarded to the user equipment, so that the user equipment obtains the IPv6 prefix address in the router advertisement message, and generates the source IPv6 address of the IPv6 data packet based on the IPv6 prefix address and the IPv6 suffix address.
The source IPv6 address may refer to a source address sent by the IPv6 packet, for example, the source IPv6 address may be an IPv6 address of the user equipment.
Specifically, fig. 6 is a schematic flow chart of obtaining an IPv6 prefix address, as shown in the drawing; the user plane network element in the server modifies the IPv6 address and the port information added by the session management network element in the RA message into the IPv6 address and the port information of the 5G base station, and after the 5G base station receives the RA message, the IPv6 address and the port information modified by the user plane network element are removed, and the RA message is forwarded to the user equipment, so that the user equipment obtains the IPv6 prefix address in the RA message.
In one embodiment, generating the source IPv6 address of the IPv6 data packet based on the IPv6 prefix address and the IPv6 suffix address includes concatenating the IPv6 prefix address and the IPv6 suffix address to generate the source IPv6 address of the IPv6 data packet.
For example, if the IPv6 prefix address is 2001:0000:0000:0000 and the IPv6 suffix address is 0000:0000:0023, the source IPv6 address of the IPv6 packet obtained by concatenating the IPv6 prefix address and the IPv6 suffix address is 2001:0000:0000:0000:0000:0000:0023.
In this embodiment, a router request message sent by a user equipment is received; acquiring a physical address of a session management network element in a 5G core network; forwarding the router request message to the session management network element according to the physical address of the session management network element so as to enable the session management network element to return a router advertisement message; and forwarding the router advertisement message returned by the session management network element to the user equipment so that the user equipment obtains the IPv6 prefix address in the router advertisement message, and the IPv6 prefix address for sending the IPv6 data packet is obtained efficiently, namely, the user equipment generates the source IPv6 address of the IPv6 data packet based on the IPv6 prefix address and the IPv6 suffix address.
In one embodiment, as shown in FIG. 7, the step of obtaining the target physical address includes:
s702, determining the corresponding multicast according to the target multicast physical address.
The multicast may refer to a packet of an IPv6 address, a multicast IPv6 address, or a multicast physical address based on a preset condition, for example, the preset condition may be that the IPv6 address with the same post-fixed bit may be regarded as the same packet or the multicast physical address with the same post-fixed bit may be regarded as the same packet.
For example, the preset condition is that six bits of the multicast physical address are identical and are the same multicast, multicast 1 is 33:33:ff:00:00:23, multicast 2 is 33:33:ff:00:00:24, and the target multicast physical address is 33:33:ff:00:00:23, so that the multicast corresponding to the target multicast physical address is multicast 1.
S704, inquiring a target address consistent with the target IPv6 address in the multicast.
The target address refers to an IPv6 address corresponding to a multicast physical address in multicast and consistent with the target IPv6 address.
Specifically, a user plane network element in a server sends an NS message to a node in a multicast, when an IPv6 address of the node in the multicast is consistent with a target IPv6 address, the node is a target node, the IPv6 address of the node is a target address, a physical address of the target node is a target physical address, and the target node generates a corresponding RA message according to the target physical address and returns the RA message.
For example, destination IPv6 addresses 2001:0000:0000:0000:0000:0000:0023 generate destination multicast physical addresses 33:33:ff:00:00:23, and destination addresses 2001:0000:0000:0000:0000:0023 for 2001:0000:0000:0000:0000:0000:0000:0023,2001:0000:0000:0000:0000:0000:0100:0023,2001:0000:0000:0000:0000:0020:0000:0023, corresponding to IPv6 addresses in the multicast.
S708, obtaining a target physical address corresponding to the target address.
Specifically, the user plane network element in the server may receive the RA message of the target node, and obtain the target physical address in the RA message.
For example, where the target address is 2001:0000:0000:0000:0000:0000:0023, the corresponding target physical address may be IntelCor b9:3c:c8 (00:1b:21:b9:3c:c8).
In this embodiment, the corresponding multicast is determined according to the target multicast physical address, and the target address consistent with the target IPv6 address in the multicast is queried to obtain the target physical address corresponding to the target address. The method realizes the efficient acquisition of the corresponding target physical address in the corresponding multicast. Compared with the mode of addressing by broadcasting in the traditional scheme, the addressing efficiency is greatly improved.
