The embodiment of the invention proposes a kind of ECT smooth migration method, by the realization details in the definition ECT smooth migration process, reducing the interruption of I-SID flow in the ECT transition process as far as possible, and realizes the smooth migration of ECT; Wherein, the method can be applied to the SPBM network, and the network equipment in this SPBM network is BEB equipment or BCB equipment.As shown in Figure 3, the method can may further comprise the steps:
Step 301, the network equipment is knowing that I-SID(is follow-up take I-SID1 as example) flow need to move to the flow that the 2nd B-VLAN(namely disposes I-SID1 from a B-VLAN and move to the 2nd B-VLAN by a B-VLAN) time, broadcast a LSP(Link State Protocol Data Unit, Link State Protocol Data Unit) message and the 2nd LSP message.Wherein, for each network equipment in the SPBM network, its processing procedure is identical, describes for convenient, and follow-up processing with a network equipment describes.
In the embodiment of the invention, the VLAN ID of B-VLAN and B-VID(provider backbone) corresponding, namely the network equipment is broadcasted a LSP message and the 2nd LSP message when the flow of knowing I-SID1 need to be moved to the 2nd B-VID from a B-VID; Follow-uply describe as an example of B-VLAN example.
In the embodiment of the invention, a LSP message is used for the corresponding relation of notice B-VLAN and ECT, and has carried the corresponding relation of the 2nd B-VLAN and the 2nd ECT in the LSP message; Further, the U-bit in the LSP message can set be the first sign (such as 1), and U-bit is i.e. the 2nd B-VLAN of B-VLAN(of the current notice of the first sign expression) on carry the flow of I-SID1.
In the embodiment of the invention, the 2nd LSP message is used for the corresponding relation of notice I-SID and B-VLAN, and has carried the corresponding relation of I-SID1 and the 2nd B-VLAN in the 2nd LSP message; Further, the R mark in the 2nd LSP message can set be the second sign (1), and the T mark can set be the 3rd sign (such as 1); Wherein, this R is labeled as the flow that second network equipment that identifies expression transmission the 2nd LSP message can receive I-SID1, and this T is labeled as the flow that the 3rd network equipment that identifies expression transmission the 2nd LSP message can send I-SID1.
Step 302, the network equipment is when a LSP message of receiving other network equipment and the 2nd LSP message, utilize the I-SID1 and the corresponding relation of the 2nd B-VLAN and the corresponding relation of the 2nd B-VLAN and the 2nd ECT that wherein carry, determine that I-SID1 is corresponding to the 2nd ECT, and utilize the 2nd ECT to carry out topology and calculate, obtain the second clean culture tunnel corresponding to I-SID1.
Concrete, the network equipment is at the corresponding relation that is resolved to I-SID1 and the 2nd B-VLAN from the 2nd LSP message, after from a LSP message, being resolved to the corresponding relation of the 2nd B-VLAN and the 2nd ECT, the flow that can know I-SID1 will be carried in the SPT set that calculates by the 2nd ECT, therefore the network equipment can utilize the 2nd ECT to carry out topology calculating, obtain the second clean culture tunnel corresponding to I-SID1 (comprising clean culture list item and clean culture tunnel information), repeat no more in this computational process embodiment of the invention.
Step 303, the network equipment is receiving that all specified network equipment (are before the flow of I-SID1 is moved to the 2nd B-VLAN from a B-VLAN, broadcasted the network equipment of the corresponding relation of I-SID1 and a B-VLAN) a LSP message and the 2nd LSP message before, utilize the first clean culture tunnel corresponding to I-SID1 to send the flow of I-SID1; The network equipment utilizes the second clean culture tunnel corresponding to I-SID1 to send the flow of I-SID1 behind a LSP message of receiving all specified network equipment and the 2nd LSP message.
In the embodiment of the invention, before the flow of I-SID1 is moved to the 2nd B-VLAN from a B-VLAN, need the flow by clean culture tunnel transmission I-SID1 corresponding to a B-VLAN, therefore the network equipment can carry out topology calculating based on an ECT corresponding to a B-VLAN, obtains the first clean culture tunnel corresponding to I-SID1; Then before a LSP message of receiving all specified network equipment and the 2nd LSP message, utilize the first clean culture tunnel corresponding to I-SID1 to send the flow of I-SID1.
Concrete, the network equipment is after obtaining the second clean culture tunnel corresponding to I-SID1, before a LSP message of receiving all specified network equipment and the 2nd LSP message, the first clean culture tunnel that I-SID1 is corresponding can not be by the second clean culture tunnel coverage corresponding to I-SID1, the first clean culture tunnel corresponding to I-SID1 this moment is primary clean culture tunnel, and the second clean culture tunnel that I-SID1 is corresponding is clean culture for subsequent use tunnel; Be the flow that the second clean culture tunnel corresponding to I-SID1 can receive I-SID1, but can not send the flow of I-SID1; The first clean culture tunnel that I-SID1 is corresponding can receive the flow of I-SID1, also can send the flow of I-SID1.
Based on this, the flow that the network equipment utilizes the first clean culture tunnel corresponding to I-SID1 to send I-SID1 comprises: for the flow of receiving I-SID1 by the first clean culture tunnel corresponding to I-SID1 or the second clean culture tunnel, the network equipment all utilizes the first clean culture tunnel corresponding to I-SID1 to send the flow of I-SID1.
In the embodiment of the invention, at the flow of I-SID1 after a B-VLAN is moved to the 2nd B-VLAN, need the flow by clean culture tunnel transmission I-SID1 corresponding to the 2nd B-VLAN, therefore the network equipment can carry out topology calculating based on the 2nd ECT corresponding to the 2nd B-VLAN, obtains the second clean culture tunnel corresponding to I-SID1; Then after a LSP message of receiving all specified network equipment and the 2nd LSP message, utilize the second clean culture tunnel corresponding to I-SID1 to send the flow of I-SID1.
Concrete, the network equipment detects by the 2nd LSP message to the corresponding relation that carries I-SID1 and the 2nd B-VLAN, all issued the corresponding relation of I-SID1 and the 2nd B-VLAN if know all specified network equipment (namely there is the network equipment of the corresponding relation of I-SID1 and a B-VLAN in all), think that then ECT moves configuration and finishes, the flow migration of beginning I-SID1; Because the difference of LSP message transfer time and each network device computes ability, in the network all-network equipment begin time of ECT migration can be variant, therefore behind a LSP message of receiving all specified network equipment and the 2nd LSP message, the not at once deletion of the first clean culture tunnel that I-SID1 is corresponding, the first clean culture tunnel corresponding to I-SID1 this moment is clean culture for subsequent use tunnel, and the second clean culture tunnel that I-SID1 is corresponding is primary clean culture tunnel; Be that the first clean culture tunnel corresponding to I-SID1 can receive the flow of I-SID1, but can not send the flow of I-SID1; The second clean culture tunnel that I-SID1 is corresponding can receive the flow of I-SID1, also can send the flow of I-SID1.
Based on this, the flow that the network equipment utilizes the second clean culture tunnel corresponding to I-SID1 to send I-SID1 comprises: for the flow of receiving I-SID1 by the first clean culture tunnel corresponding to I-SID1 or the second clean culture tunnel, the network equipment all utilizes the second clean culture tunnel corresponding to I-SID1 to send the flow of I-SID1.
In sum, in the embodiment of the invention, by in ECT smooth migration process, the flow that uses primary clean culture tunnel to carry out I-SID1 sends, and use primary clean culture tunnel and clean culture for subsequent use tunnel to carry out the flow reception of I-SID1, thereby guarantee the Flow continuity of I-SID1.
In the embodiment of the invention, the network equipment is behind a LSP message of receiving all specified network equipment and the 2nd LSP message, also need to broadcast the 3rd LSP message for deletion the first clean culture tunnel, the 3rd LSP message is used for the corresponding relation of notice I-SID and B-VLAN, and has carried the corresponding relation of I-SID1 and a B-VLAN in the 3rd LSP message;
R mark in the 3rd LSP message can set be the second sign (1), and the T mark can set be the 4th sign (such as 0); Wherein, this R is labeled as the flow that second network equipment that identifies expression transmission the 3rd LSP message can receive I-SID1, and this T is labeled as the flow that the 4th network equipment that identifies expression transmission the 3rd LSP message cannot send I-SID1.
Further, the network equipment no longer needs to send the 3rd LSP message of the corresponding relation that carries I-SID1 and a B-VLAN after receiving the 3rd LSP message of all specified network equipment; When not carrying the corresponding relation of I-SID1 and a B-VLAN among the LSP of all-network equipment issue in the network, the first clean culture tunnel corresponding to deletion I-SID1, this moment, the first clean culture tunnel no longer carried the flow of I-SID1.
In addition, at the flow of I-SID1 after a B-VLAN is moved to the 2nd B-VLAN, if do not carry the flow of any I-SID on the B-VLAN, then the network equipment also needs to send the LSP message of the corresponding relation that carries a B-VLAN and an ECT, and the U-bit in this LSP message can set be the 5th sign (such as 0), and U-bit is the i.e. B-VLAN of B-VLAN(of the current notice of the 5th sign expression) on do not carry the flow of any I-SID.
