Embodiment Construction
[0069] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and various manners in the embodiments can be combined with each other.
[0070] see image 3 , the present invention proposes a multi-segment pseudo-wire removal method, the multi-segment pseudo-wire removal method comprising:
[0071] Step 110, the first PE sends a label revocation message and an active label release message to the second PE, and clears the label mapping relationship corresponding to the first PW; wherein, the first PW is a pseudowire connection between the first PE and the second PE .
[0072] In the embodiment of the present invention, when the starting condition is met, the first PE performs the steps in step...

The invention discloses a method and device for removing a multi-segment pseudo-wire, including that a first PE sends a label revocation message and an active label release message to a second PE, and clears the label mapping relationship corresponding to the first PW; wherein, the first PW is the first PW A pseudowire connection between a PE and a second PE; the first PE receives a label release message corresponding to the label revocation message sent by the second PE; after receiving the corresponding label release message, the first PE recycles the Local resources occupied by a PW. Through the solution of the present invention, after the PE receives the label release message sent by the adjacent PE, it can complete the dismantling of the local resources occupied by the PW. Compared with the prior art, the signaling overhead in the dismantling process provided by the present invention is smaller , the demolition speed is faster, and the resource occupation time is reduced, which is conducive to the rapid convergence of network changes.
Description
technical field [0001] The invention relates to the field of data network communication, in particular to a method and device for removing a multi-segment pseudo-wire. Background technique [0002] With the development of IP data network, IP network itself has very strong expandability, upgradeability, compatibility and interoperability. However, the flexibility of upgrade, expansion and intercommunication of traditional communication networks (such as FR network and ATM network) is relatively poor; limited by the way of transmission and the type of business, therefore, the commonality of the new network is relatively poor, and it is not suitable for intercommunication management. The end-to-end pseudo-wire emulation (PWE3, Pseudo-Wire Emulation Edge-to-Edge) technology provides The service of transmitting user's Layer 2 messages such as Ethernet, frame relay, and asynchronous transfer mode on the packet switching network. Because the PWE3 technology can allow different s...
