Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
It should be noted that in the case of not conflicting, the embodiment in the present invention and the feature in embodiment can phases
Mutually combine.To describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
In embodiments of the present invention, in order that the MTU value in P2MP tunnel adapts to multiple peer network device, thus passing through
When P2MP tunnel sends message, it can be avoided that peer network device carries out pack burst again to message, lift peer network device
Performance, the network equipment, can be according to its destination address, from the tunnel MTU value of coupling when sending message.Further, may be used
With according to this tunnel MTU value, it is determined whether burst is carried out to message.Such that it is able to avoid the network equipment first message to be packaged
Burst more afterwards, leads to peer network device to need message is carried out first pack burst again.
Embodiments provide a kind of file transmitting method, process is as shown in figure 1, this process can include following walking
Suddenly：
S101, determines the destination address of message, and right in the local each destination address preserving and each MTU value in P2MP tunnel
In should being related to, search the target tunnel MTU value mated with described destination address.
Method provided in an embodiment of the present invention, can apply to the network equipment.Specifically, this network equipment can be P2MP
The tunnel transmitting terminal network equipment.Wherein, this network equipment can be switch, router etc..
The network equipment can be in the local corresponding relation preserving each destination address and each MTU value in P2MP tunnel.That is,
In the network device, P2MP tunnel is to should have multiple MTU value.Wherein, each MTU value can be basis and each destination address pair
The MTU value of the physics outgoing interface answered determines.For example, it is possible to corresponding for each destination address tunnel MTU value is defined as this purpose
Address corresponding physics outgoing interface MTU value deducts tunnel encapsulation head size.
Specifically, in embodiments of the present invention, when the network equipment sends message, the destination of message can be determined first
Location.It is possible to further in the corresponding relation of each destination address locally preserving and each MTU value in P2MP tunnel, searching and being somebody's turn to do
The target tunnel MTU value of destination address coupling.
For example, the local each destination address preserving of the network equipment can be as follows with the corresponding relation of each MTU value in P2MP tunnel
Shown in table：
| Destination address | Tunnel MTU value |
| Main frame 1 | 1476 |
| Main frame 2 | 1376 |
| Main frame 3 | 1476 |
When the destination address of network equipment message to be sent is main frame 2, it can find the tunnel mating with main frame 2
Road MTU value is 1376.
S102, according to described target tunnel MTU value, it is determined whether carry out burst to described message；If it is, execution step
S103, if not, execution step S104.
After determining target tunnel MTU value, the network equipment can be further according to this target tunnel MTU value, it is determined whether right
Message carries out burst.
For example, the network equipment may determine that whether the size of message is more than target tunnel MTU value, if it does, showing to need
Burst is carried out to message；If it is not greater, showing not need to carry out burst to message.
S103, carries out burst to described message, and after the message after burst is packaged, by with described destination address
Corresponding physics outgoing interface sends.
When network equipment determination needs to carry out burst to message, it can carry out burst to this message.The network equipment pair
Message carries out the process of burst, can adopt existing method, and the embodiment of the present invention does not repeat to this process.
And, before message is sent to tunnel, the message after burst can also be packaged by the network equipment.For example,
The network equipment can be searched local forward table, find corresponding tunnel destination address according to the destination address of this message, will
Outer layer destination address is set to tunnel destination address, completes the encapsulation to this message.
After completing the encapsulation to message, the network equipment can be sent by physics outgoing interface corresponding with this destination address should
Message.
The network equipment is when sending message, corresponding with each MTU value in P2MP tunnel according to the local each destination address preserving
Relation, finds corresponding MTU, and in this case, when message size is more than corresponding tunnel MTU value, the network equipment is just permissible
First burst is carried out to this message, then the message after burst is packaged.Tunnel MTU value due to finding is according to corresponding
Physics outgoing interface MTU value determines, accordingly, it is capable to ensure the message after encapsulation, when port sends, less than physics outgoing interface
MTU, also would not be by the secondary burst of physics outgoing interface.
S104, after described message is packaged, is sent by described physics outgoing interface.
When network equipment determination does not need to carry out burst to message, this message can be packaged by it.For example, network
Equipment can be searched local forward table, find corresponding tunnel destination address, by outer layer according to the destination address of this message
Destination address is set to tunnel destination address, completes the encapsulation to this message.
After completing the encapsulation to message, the network equipment can be sent by physics outgoing interface corresponding with this destination address should
Message.So that after peer network device receives this message, first decapsulation fragment message can be obtained, when it determines that needs continue
Continuous when forwarding each fragment message, when each fragment message size no more than corresponding physics outgoing interface MTU value when, opposite end net
Each fragment message can directly be forwarded by network equipment, thus avoiding peer network device to message elder generation pack burst again.
Embodiments provide a kind of file transmitting method, the network equipment can local preserve each destination address with
The corresponding relation of each MTU value in P2MP tunnel, by P2MP tunnel send message before, can according to the destination address of this message,
Obtain corresponding target tunnel MTU value, and then can be according to this target tunnel MTU value, it is determined whether burst is carried out to message.Cause
This, it is to avoid when the higher value that tunnel MTU is acquiescence, before encapsulation, burst is not carried out to message, and because message is big after encapsulating
The little MTU value more than physics outgoing interface and need burst, thus the receiving terminal network equipment leading to carries out pack to message dividing again
Piece is such that it is able to lifting receiving terminal performance of network equipments lifts receiving terminal performance of network equipments.
In some cases, in the corresponding relation of the local each destination address preserving of the network equipment and each tunnel MTU value, have
Tunnel MTU value is default value, i.e. maximum.Even if being set to maximum, if message has exceeded port after sealing up dress
MTU value, then message still can carry out burst at port.
Therefore, in embodiments of the present invention, get in order to ensure the network equipment is the tunnel mating with destination address
MTU value, can be according to the tunnel MTU value of destination address corresponding physics outgoing interface adjustment, it is to avoid peer network device is to message
Carry out the problem of pack burst again, lift peer network device performance.Specifically, the network equipment can be by physics outgoing interface
MTU value deducts tunnel encapsulation head size, obtains tunnel MTU value.
It is appreciated that in actual applications, the MTU value of physics outgoing interface may be reconfigured.Therefore, in the present invention
In embodiment, when the MTU value of network equipments configuration arbitrary physics outgoing interface, its can by the local each destination address preserving with
In the corresponding relation of each MTU value in P2MP tunnel, each MTU value is each configured to default value, such as 64000.MTU when physics outgoing interface
During value changes, the local each destination address preserving all is configured with each MTU value in the corresponding relation of each MTU value in P2MP tunnel simultaneously
For default value, each MTU value locally preserving can be avoided inconsistent with the MTU value of physics outgoing interface, further avoid transmission
During message, need peer network device that message is carried out with pack burst again.
Further, the network equipment is getting target tunnel MTU value, according to this target tunnel MTU value, it is determined whether right
Before message carries out burst, can also judge whether this target tunnel MTU value is default value.
For example, according to known default value, the network equipment can judge whether the target tunnel MTU value getting is that this is write from memory
Recognize value.
When the network equipment confirms that the target tunnel MTU value getting is default value, sent by this target tunnel MTU value
Message, may result in peer network device and message carried out with pack burst again.In this case, the network equipment can determine
The MTU value of this destination address corresponding physics outgoing interface, according to this MTU value, calculates tunnel MTU value, and more fresh target tunnel MTU
It is worth for calculated tunnel MTU value.
By judging whether target tunnel MTU value is default value, if it is, mesh is updated according to corresponding physics outgoing interface
Mark tunnel MTU value, ensure that the target tunnel MTU value that the network equipment gets is the tunnel according to corresponding physics outgoing interface adjustment
Road MTU value, and then guarantee that peer network device will not carry out pack burst again to message, lift peer network device performance.GRE
(Generic Routing Encapsulation, generic route encapsulation) tunnel is a kind of common tunnel, e.g., P2MP GRE
Tunnel.
The present embodiment, specifically with the network architecture shown in Fig. 2, describes this file transmitting method in detail.Net as shown in Figure 2
In network framework, set up between host A and network equipment A and be connected；Set up between network equipment A and network equipment B and network equipment C
P2MP gre tunneling；Set up between host B and network equipment B and be connected.
In the network architecture shown in Fig. 2, P2MP gre tunneling in network equipment A is to should have two correspondent network to set
Standby, i.e. network equipment B and network equipment C.Network equipment A may be gone out by different physics by the message of P2MP gre tunneling
Interface is sent respectively to network equipment B or network equipment C.And the MTU value of the P2MP gre tunneling of network equipment A can not be fitted simultaneously
Answer network equipment B and network equipment C, for example, it is possible to be configured as adapting to the tunnel MTU value of network equipment C, such as 3376.
Below so that the message of host A one 2000 size of transmission is to host B as a example, to illustrate that existing message is transmitted across
Journey.
This message is sent to network equipment A by host A, and wherein, the destination address of this message is the address of host B.Network
After device A receives this message, determine that this message size is 2000, the MTU value of the P2MP gre tunneling of local terminal is 3376, because
This, network equipment A will not be to this message fragment.
Network equipment A is directly packaged to this message.Specifically, network equipment A can be according to the destination of this message
Location, i.e. the address of host B, local forward table finds corresponding tunnel destination address, i.e. network equipment B.Thus will
Outer layer destination address is set to the address of network equipment B, completes the encapsulation to this message.
It is assumed that the MTU value of the physics outgoing interface of network equipment A map network equipment B is 1500, after network equipment A encapsulation
Message size be original message size 2000, encapsulation header 24 (IP 20 and GRE 4), as 2024.
When message after encapsulation passes through corresponding physics outgoing interface transmission, because its size is more than this physics outgoing interface
MTU value, therefore, network equipment A need to carry out burst to this message.For example, this message can be divided into two panels by network equipment A, often
The size of piece is respectively less than or is equal to 1500.
Network equipment B can receive two fragment messages of network equipment A transmission.After receiving fragment message, network
Equipment B first can carry out pack to fragment message, obtains a complete channel message.Decapsulate again, after decapsulation, obtain one
The original message of individual 2000 sizes.
Network equipment B obtains the destination address comprising in original message, the as address of host B.Therefore, network equipment B
Need to forward the packet to host B.
It is assumed that the MTU value of the physics outgoing interface of network equipment B respective hosts B is 1500, network equipment B forwards the message to
During host B, the size of this message is more than the MTU value of this physics outgoing interface, and therefore, network equipment B need to carry out burst to this message.
For example, this message can be divided into two panels by network equipment B, and the size of every is respectively less than or is equal to 1500.
Host B can receive two fragment messages of network equipment B transmission.After receiving fragment message, host B judges
The destination of this message is the machine, and host B can carry out pack to fragment message, obtain a complete original message.
Can be seen that from above-mentioned flow process and each correspondent network is not adapted to due to the P2MP tunnel MTU value at network equipment A end
Equipment, thus leading to same message, has made burst on network equipment A, first pack on network equipment B, then burst, host B
On pack again.That is, peer network device needs pack burst more simultaneously, can greatly affect the property of peer network device
Energy.
In embodiments of the present invention, the network equipment can preserve each destination address and each MTU value in P2MP tunnel local
Corresponding relation.Specifically, as shown in figure 3, the network equipment preserves each destination address and the corresponding relation of each MTU value in P2MP tunnel
Process can include：
S301, receives GRE message, and obtains the source address of described GRE message.
In embodiments of the present invention, the network equipment can receive the GRE message of peer network device transmission, and obtains this
The source address of GRE message.Wherein, above-mentioned peer network device can be the arbitrary network equipment in P2MP tunnel opposite end.For example, as schemed
In the network architecture shown in 2, GRE message can network equipment B send or network equipment C send.
The outer layer source address of the message that the source address of this message can receive for the network equipment, or or net
After network equipment decapsulates to this message, the source address of the original message of acquisition.
For example, taking the network architecture shown in Fig. 2 as a example, when host B sends message to host A, host B will be to the network equipment
B sends original message, and the source address of this original message is the address of host B.After network equipment B receives this original message, its
This original message can be encapsulated, its outer layer source address is set to the address of network equipment B, and the message after encapsulation is sent
To network equipment A.
Network equipment A will receive after the message that network equipment B sends, and it can get the outer layer source ground of this message
Location, i.e. the address of network equipment B；Or, after it can also decapsulate to this message, get the source of internal layer original message
Address, i.e. the address of host B.
S302, according to described source address, and the local forward table preserving, determine that the physics with described source address matches goes out
Interface；And obtain the MTU value of this physics outgoing interface, according to this MTU value, calculate tunnel MTU value.
When network equipment A receives the message of network equipment B transmission, and after getting the source address of message, can also root
According to this source address, and the local forward table preserving, determine the physics outgoing interface with this source address matches.
Further, network equipment A can also obtain the MTU value of this physics outgoing interface, and according to this MTU value, calculates tunnel
Road MTU value.
That is, network equipment A can determine in the multiple physics outgoing interfaces of itself, to should source address physics
Outgoing interface.Further determine the MTU value of this physics outgoing interface, and then the MTU value according to this physics outgoing interface, calculate tunnel
MTU value.For example, the MTU value of physics outgoing interface can be deducted tunnel encapsulation head size by network equipment A, obtain tunnel MTU value.
S303, using described source address as destination address, preserves this destination address and calculated tunnel MTU local
The corresponding relation of value.
Calculated tunnel MTU value is also and the physics outgoing interface corresponding tunnel MTU value receiving this message.Also
It is to say, when network equipment A sends message, according to this tunnel MTU value, message is carried out after burst, can directly be gone out by this physics
Interface sends burst the message after encapsulating.
It is appreciated that the source address in the message that receives of network equipment A, as follow-up this network equipment A sends message
When destination address.
When therefore, in order to instruct follow-up transmission message, how burst is carried out to message, network equipment A can be by source address
As destination address, in the local corresponding relation preserving this destination address and calculated tunnel MTU value.In this case,
When network equipment A sends message to the corresponding equipment of this destination address, it can enter to message according to this tunnel MTU preserving
Row burst, you can the message after ensureing burst and encapsulating can be sent by physics outgoing interface, thus peer network device will not
Message is carried out with pack burst again, lifts peer network device performance.
Alternatively, in embodiments of the present invention, network equipment A can be corresponding with each tunnel MTU value by each destination address
Relation is saved in the Hash table of the network equipment, when searching the target tunnel MTU mating with destination address, to improve and to search effect
Rate.For example, the tunnel MTU value that network equipment A can will preserve for each destination location, is saved in a node of Hash table
In.
