Embodiment Construction

[0022] Please refer to figure 1 As shown, in the SPBM technology, a backbone network (Core Network), such as an operator network, is usually called an SPT (Shortest Path Tree, shortest path tree) domain. The SPT domain usually includes two kinds of SPB devices: BEB (Backbone Edge Bridge, backbone network edge bridge) device and BCB (Backbone Core Bridge, backbone network core bridge) device. The BEB device is the edge device of the backbone network. In terms of role, it is equivalent to the PE (Provider Edge, service provider network edge) in the MPLS VPN (Multi Protocol Label Switching Virtual Private Network, virtual private network based on the multi-protocol label switching protocol) network. ) device, responsible for Mac-in-Mac (hereinafter referred to as "MinM") encapsulation of user packets from the user network, and forwarding to the backbone network; or decapsulation of MinM packets from the backbone network, and forwarding to the in the user network. The BCB device...

Abstract

The invention provides a neighbor multilink processing method and a neighbor multilink processing device. The neighbor multilink processing method and the neighbor multilink processing device are applied to SPB (shortest path bridging) network equipment in an SPB network. The neighbor multilink processing method comprises the steps that a local port connected with neighbor equipment is determined according to a neighbor message transmitted by the neighbor equipment; when multiple local ports are connected with the neighbor equipment, the local ports are used as member ports to create a virtual port oriented to the SPB network; the virtual port is used as a neighbor port connected with the neighbor equipment, and the attribute information of the virtual port is broadcasted through a protocol message; when an SPB data message is forwarded, for the SPB data message taking the virtual port as the output port, one of the member ports in normal state, corresponding to the virtual port, is selected to transmit the SPB data message according to a preset load sharing algorithm. Compared with the prior art, the neighbor multilink processing method and the neighbor multilink processing device avoid the problem that the load sharing cannot be realized in the MSTP (multi-service transmission platform) routing process in the SPB network by introducing the virtual port.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a neighbor multi-link processing method and device. Background technique [0002] SPB (Shortest Path Bridge, the shortest path bridge) is one of the Ethernet standards defined by IEEE802.1aq. In a sense, the SPB technology is regarded as a further extension of the multi-instance spanning tree protocol (MSTP), aiming at building a large flat non-blocking Layer 2 network. In SPB technology, each node uses SPB-ISIS (Intermediate System to Intermediate System Routing Protocol, intermediate system to intermediate system routing protocol) to share the link status in the network, and each device in the SPB network calculates the link status between each node in parallel. The shortest path avoids the instability caused by the use of STP (Spanning Tree Protocol, Spanning Tree Protocol) and the inefficiency of some links. SPB technology also has the advantages of sim...
