Embodiment Construction

[0022] In order to effectively reduce the maintenance cost of PTN equipment, save resources and improve configuration flexibility, the present invention provides an MPLS-TP configuration method and device based on a three-layer interface.

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] figure 1 A schematic diagram of a three-layer interface-based MPLS-TP configuration process provided by the embodiment of the present invention, the process includes the following steps:

[0025] S101: Receive the configuration start command to wake up the synchronous semaphore, search the corresponding VLAN interface information in the label address table saved by itself according to the label information and the next-hop IP address information, and send the label information through each VLAN interface found. ARP request message, wherein the label address table stores label information, next-hop IP address information, V...

Abstract

An embodiment of the invention provides a three-layered interface based MPLS-TP (multi-protocol label switching-transport profile) configuration method and device. The method includes: according to VLAN (virtual local area network) interface information in a self-stored label address table, sending an ARP (address resolution protocol) request message of label information through each VLAN interface; receiving a returned ARP reply message of the label information, comparing MAC (media access control) address information and out interface information carried in the ARP reply message with information in the label address table, and when destination MAC address information in the label address table is inconsistent with the out interface information, updating the label address table. Due to creation of a mapping list of the label information, next-hop IP (internet protocol) address information, the VLAN information, the out interface information and the destination MAC address information, when network topology changes, information for labeling next-hop nodes can be updated timely, and further flexibility in PTN (packet transport network) equipment configuration is improved greatly.

Description

technical field [0001] The invention relates to the technical field of industrial network communication, in particular to an MPLS-TP configuration method and device based on a three-layer interface. Background technique [0002] The large-scale application of 3G transmission and IP data communication has enriched the rapid development of packet switching technology. The Layer 2 virtual private network (Virtual Private Network, VPN) solution based on Multi-Protocol Label Switching - Transport Profile (MPLS-TP) overcomes the shortcomings of traditional ATM or FR network expansion complexity, By using the label stack technology, MPLS-TP VPN can multiplex multiple virtual circuits in a layered service provider (Layered Service Provider, LSP), and the provider edge (PE) only needs to maintain one LSP information, thus greatly improving the system scalability. MPLS-TP L2 VPN reduces the complexity of VPN service provisioning and enhances security, especially when adding sites to...
