Problems solved by technology

[0004] However, after analyzing the PBB-TE, the inventor found that: the PBB-TE tunnel is statically configured, and cannot automatically converge to generate a new route when a link fails; when the network topology changes, such as adding a new node, other Relevant nodes need to be reconfigured

Embodiment Construction

[0024] The embodiment of the present invention provides a method for dynamic signaling control, by using MP-BGP to realize B-DA (Backbone Destination MAC Address, backbone network destination MAC address) and B-VID (Backbone VLAN ID, backbone network VLAN ID) Information is transmitted between different devices, thereby realizing the dynamic creation of PBB-TE tunnels. Among them, the encapsulation format of PBB-TE is as follows: figure 1 As shown, including: B-DA, S-SA (Backbone Source MAC Address, backbone network source MAC address), TPID (EtherType Identifier, Ethernet type identifier), B-VID, I-SID and payload; B-TAG (outer label) as the tunnel identifier, and I-TAG (inner label) as the identifier of the service instance.

[0025] In the embodiment of the present invention, a PBB-TE tunnel is created according to the target B-DA and B-VID, where B-DA is used to uniquely identify a PBB-TE device in the entire network, and B-VID is used to identify the PBB-TE device in the...

Abstract

The invention discloses a method, a system and device for signaling control. The method comprises the steps that: a destination MAC address of a local backbone network and VLAN ID of the backbone network are configured and added into a local topology table; the destination MAC address of the local backbone network and the VLAN ID of the backbone network are transmitted to an adjacent device by a multiprotocol border gateway protocol (MP-BGP) and the destination MAC address of the local backbone network and the VLAN ID of the backbone network sent by the adjacent device by the MP-BGP are received and stored in the local topology table; a provider backbone bridge-traffic engineering (PBB-TE) tunnel is established according to information in the local topology table. In the embodiment of theinvention, the PBB-TE tunnel is dynamically established according to the information carried by the MP-BGP and a new tunnel can be automatically generated in a convergent manner when a link circuit fails; when network topologies change, for example, new nodes are added, nodes relevant to the new nodes can automatically update without need of manual configuration.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, system and equipment for signaling control. Background technique [0002] With the development of IP-based networks, Ethernet as an IP bearer network has been widely used. At the beginning, Ethernet was mainly concentrated on the access side and aggregation side. Due to the limitation of the number of VLAN (Virtual Local Area Network, Virtual Local Area Network) addresses on the core side, it was not widely used until the emergence of MinM (Mac in Mac, MAC nesting protocol) , to solve the problem of the number of VLAN restrictions, so that the application of Ethernet in the core network becomes possible. However, since the forwarding of the Ethernet message adopts the manner of MAC (Media Access Control, Media Access Control) address learning, the application in the core network is also limited by the number of MAC entries in the Ethernet switch.
