Each device on the FRRP ring is called a node on the FRRP ring, the nodes of the FRRP ring are divided into a main node and a transmission node, wherein each FRRP ring is provided with only one main node, and the main node can actively send a detection message to check the link state; all other nodes except the main node on the FRRP ring are transmission nodes, and the transmission nodes are responsible for transmitting protocol messages and monitoring the state of own adjacent links. If the transmission node detects that the adjacent link fails, the transmission node actively sends a protocol message to the ring network to notify the host node of the DOWN event of the link. The devices (main node and transmission node) in the FRRP ring are accessed to two ports of the ethernet ring, one is a main port, the other is a sub port, and the roles of the ports are determined by the configuration of a user.
The FRRP protocol supports VLAN division in a ring network, wherein a control VLAN is used for transmitting an FRRP protocol message, and a service VLAN is used for transmitting a data message, so that the isolation of control information and service data is realized.
According to the method for automatically electing the blocked port by the FRRP ring, after a user starts the FRRP function of the port of the equipment included in the FRRP ring and completes the configuration of the control VLAN and the service VLAN, the configuration of the main node and the blocked port can be automatically completed without manually configuring the main node. Through an election process, electing equipment where a port with the lowest bandwidth in the whole FRRP link is located as a unique main node, wherein the other equipment are all transmission nodes; and automatically selecting the port with low bandwidth as the secondary port through a comparison process. And then according to the existing flow, blocking the secondary port of the main node to prevent the data message from forming a broadcast loop on the ring topology.
In the method for automatically electing the blocked port by the FRRP ring, all equipment belonging to the control VLAN in the FRRP ring before the main node is generated in the non-electing process is called as an electing node, and the electing node participates in the electing of the main node.
Fig. 1 is a schematic flow chart illustrating a method for automatically electing a blocked port by an FRRP ring according to an embodiment of the present disclosure.
As shown in fig. 1, in step S102, bandwidth information is collected, and all devices included in a control VLAN in an FRRP ring are taken as election nodes, and each of the election nodes automatically collects a bandwidth information value of its port belonging to the control VLAN.
In step S104, an interactive packet is generated, and the election nodes each generate an interactive packet including a bandwidth information field and an MAC field, where a value of the bandwidth information field is a minimum bandwidth value among the collected bandwidth information values of the ports belonging to the control VLAN, and a value of the MAC field is an MAC address thereof.
More specifically, in step S102 and step S104, after the user activates the FRRP function to the port of the device participating in the FRRP ring, the election node automatically collects the bandwidth information of the port under the control VLAN, and records the minimum bandwidth information in the collected bandwidth information of the port under the control VLAN in a newly added message for exchanging information of each node. The message data structure is as follows:
| bandwidth information | MAC address |
And then each election node in the initial state before election generates the interactive message which is the main node. The bandwidth information records the bandwidth information of the port with the minimum bandwidth belonging to the control VLAN port of the FRRP ring, and the MAC address of the MAC recording device.
In step S106, each election node sends an interaction packet to a control VLAN, and each election node sends the interaction packet to the control VLAN.
In step S108, the election host node compares the received interactive packet with the generated interactive packet after receiving the interactive packet, only forwards the interactive packet whose MAC field value is smaller than the MAC field value of the generated interactive packet if the bandwidth information field value is smaller than the bandwidth information field value of the generated interactive packet and if the bandwidth information field value is the same as the bandwidth information field value of the generated interactive packet, and sets the election node as the host node when the election node finally receives the interactive packet itself sends to the control VLAN.
More specifically, in step S106 and step S108, each election node sends its own configuration message to the outside, and after receiving the message, other election nodes in the ring first view the bandwidth information: when the bandwidth information field value in the message received by the election node is smaller than the bandwidth information field value in the message generated by the election node, forwarding the message; when the bandwidth information field value in the message received by the election node is larger than the bandwidth information field value in the message generated by the election node, discarding the message and not forwarding the message; when the bandwidth information in the message received by the electing node is the same as the bandwidth information in the message generated by the electing node, comparing the MAC address value, forwarding the interactive message smaller than the MAC address value of the equipment, and discarding the interactive message larger than the MAC address value of the equipment. Therefore, only the election node with the minimum bandwidth information (or the election node with the minimum MAC) can receive the interactive message sent by the election node, and the election node is elected as the main node.
In step S110, a blocking port is set, a port having a large bandwidth information value among the ports belonging to the control VLAN included in the master node is set as a master port, and a port having a small bandwidth information value among the ports belonging to the control VLAN included in the master node is set as a blocking port.
More specifically, after the elected node is elected as the master node, the bandwidth information collected from the ports under the control VLAN in the FRRP ring is compared, and the port with the smaller bandwidth information value is selected as the secondary port (blocked port) of the master node.
The method for automatically electing the blocked port by the FRRP ring according to the embodiment of the disclosure further comprises the following steps: and setting a transmission node, comparing the received interactive message with the generated interactive message after the election node receives the interactive message, and setting the election node as the transmission node if the bandwidth information field value in the received interactive message is smaller than the bandwidth information field value of the generated interactive message or the bandwidth information field value is the same as the bandwidth information field value of the generated interactive message, and the MAC field value of the received interactive message is smaller than the MAC field value of the generated interactive message.
More specifically, in step S106 and step S108, each election node sends its own configuration message to the outside, and after receiving the message, other election nodes in the ring first view the bandwidth information: when the value of the bandwidth information field in the message received by the election node is lower than that in the message generated by the election node, the message is forwarded, and the equipment is set as a transmission node; when the bandwidth information field value in the message received by the election node is the same as the bandwidth information field value in the message generated by the election node, comparing the MAC address values, forwarding the interactive message smaller than the MAC address value of the equipment, and setting the equipment as a transmission node.
The method for automatically electing the blocked port by the FRRP ring according to the embodiment of the disclosure further comprises the following steps: and setting a port with a small bandwidth information value in ports belonging to the control VLAN and included in the transmission node as a secondary port. More specifically, for the transmission node, the primary and secondary ports have no difference in function, but may also be determined by the primary node determining the primary and secondary ports, that is: and setting the port with the small bandwidth information value of the port of the transmission node belonging to the control VLAN as the auxiliary port.
The method for automatically electing the blocked port by the FRRP ring according to the embodiment of the disclosure further comprises the following steps: the main node sends a HELLO message from a main port of the main node, when the main node receives the HELLO message at a blocking port, the blocking port is blocked to prevent a data loop, and when the main node does not receive the HELLO message from the blocking port within a specified time, the blocking port is released to ensure normal communication of all nodes in an FRRP loop.
More specifically, according to the method for automatically electing a blocked port by an FRRP ring of the embodiment of the present disclosure, after the VLAN, the service VLAN, the master node, the transmission node, and the master and slave ports of each node are configured or elected in the FRRP ring, the flow of entering the FRRP blocked port is performed, that is: the main node sends a HELLO message from a main port, if the main node can receive the message from a secondary port (a blocking port), the FRRP looped network where the main node is located is complete, and the secondary port (the blocking port) is blocked to prevent a data loop; if the message can not be received within the specified time, the ring network failure is indicated, and the secondary port (blocking port) is released to ensure the normal communication of all the nodes on the ring.
Fig. 2 is a schematic flow chart illustrating the main node election in the FRRP ring automatic port-blocking election method according to the embodiment of the present disclosure.
As shown in fig. 2, in step S202, the election node collects bandwidth information of ports under the control VLAN.
In step S204, the election node generates an interaction packet.
In step S206, the election node regards itself as the master node and sends the generated interaction packet to the control VLAN.
In step S208, it is determined whether the bandwidth of the interactive message received by the node is smaller than that of the node itself. If the result of determining in step S208 whether the bandwidth of the interactive message received by the node is smaller than that of the node itself is yes, the process proceeds to step S210. In step S210, the received interactive packet is forwarded, and the node is set as a transmission node.
If the result of determining in step S208 whether the bandwidth of the interactive message received by the node is smaller than that of the node itself is "no", the process proceeds to step S212. In step S212, it is determined whether the bandwidth of the interactive message received by the node is equal to that of the node itself. If it is determined in step S212 that the result of the node receiving the interactive message is equal to the bandwidth of the node itself is yes, the flow proceeds to step S214. In step S214, it is determined whether the MAC in the interactive message received by the node is smaller than the MAC of the node itself. If it is determined in step S214 that the result of determining whether the MAC in the interactive message received by the node is smaller than the MAC value of the node itself is yes, the flow proceeds to step S218. In step S218, the received interactive packet is forwarded, and the node is set as a transmission node.
If the result of determining whether the bandwidth of the interactive message received by the node is smaller than itself in step S208 is "no", if the result of determining whether the bandwidth of the interactive message received by the node is equal to itself in step S212 is "yes", and if the result of determining whether the MAC of the interactive message received by the node is smaller than itself in step S214 is "no", the process proceeds to step S220. In step S220, it is determined whether the MAC in the interactive message received by the node is equal to itself. If it is determined in step S220 that the result of the MAC in the interactive message received by the node being equal to itself is yes, the flow proceeds to step S222. In step S222, it is verified that the interaction packet sent by the node itself is received, and the node is set as the master node.
If the result of determining whether the bandwidth of the interactive message received by the node is smaller than the bandwidth of the node is "no" in step S208, the result of determining whether the bandwidth of the interactive message received by the node is equal to the bandwidth of the node is "yes" in step S212, the result of determining whether the MAC of the interactive message received by the node is smaller than the MAC of the node is "no" in step S214, and the result of determining whether the MAC of the interactive message received by the node is equal to the MAC of the node is "no" in step S220, the process proceeds to step S224. In step S224, the received interactive packet is discarded and is not forwarded.
If it is determined in step S208 that the bandwidth of the interactive message received by the node is smaller than that of the node itself, the process proceeds to step S216, and if it is determined in step S212 that the bandwidth of the interactive message received by the node is equal to that of the node itself, the process proceeds to step S216. In step S216, the received interactive packet is discarded and is not forwarded.

The prior art blocks the secondary port by default to prevent loops by the user manually configuring the primary node and its primary and secondary ports in the frrp loop. The invention does not need to configure the main node manually, and only needs the user to enable the frrp function of the port in the frrp ring and configure the control vlan and the service vlan. Adding a comparison process, and automatically selecting a port with low bandwidth as a secondary port; and meanwhile, an election process is added, the equipment where the port with the lowest bandwidth in the whole frrp link is located is elected as a unique main node, and the rest equipment are all transmission nodes. And then according to the existing flow, blocking the secondary port of the data message to prevent the data message from forming a broadcast loop on the ring topology. The master nodes in the frrp ring are first automatically elected. Specifically, after the user enables the frrp function of the port participating in the frrp ring, the device automatically collects bandwidth information of the port under the control vlan, and records the minimum bandwidth information in a newly added message for exchanging information of each node, where the data structure of the message includes the bandwidth information and the MAC address. In an initial state, each device generates the interactive message which is a main node, wherein bandwidth information records bandwidth information of a port with the minimum bandwidth under the frrp ring control vlan; the MAC records the MAC of the device itself. Each device sends its own configuration message to the outside, and after receiving the message, other devices in the ring first check the bandwidth information: when the bandwidth information in the message received by the equipment is lower than the bandwidth information in the message generated by the equipment, forwarding the message and setting the equipment as a transmission node; when the bandwidth information in the message received by the equipment is higher than the bandwidth information in the message generated by the equipment, discarding the message and not forwarding the message; when the bandwidth information in the message received by the equipment is the same as the bandwidth information in the message generated by the equipment, the MAC is compared, the forwarding is smaller, the equipment is set as a transmission node, and the MAC is discarded in a larger mode. Thus, only the device with the minimum bandwidth information (or the device with the minimum MAC) can receive the interactive message sent by itself, and the device is elected as the master node. The master node then determines the primary port and the secondary port. After the device is elected as a main node, the bandwidth information collected from the ports under the control vlan in the frrp ring is compared, and the port with the low bandwidth is selected as a secondary port. The transmission node then determines the primary port and the secondary port. There is no difference in the functionality of the primary and secondary ports for the transmission node. The method for determining the primary and secondary ports by the main node can also be adopted. The secondary port is then blocked to ensure no loops in the link. So far, the main node, the transmission node, the main and auxiliary ports of each node, the control vlan, the service vlan, etc. in the frrp ring are configured or elected, and the flow of frrp blocking ports in the prior art is entered: the main node sends a HELLO message from a main port of the main node, if the main node can receive the message from a secondary port, the FRRP looped network where the main node is located is complete, and the secondary port is blocked to prevent a data loop; if the message can not be received within the specified time, the ring network failure is indicated, and the secondary port is opened to ensure the normal communication of all the nodes on the ring.
