Embodiment Construction

[0022] The embodiments of the present invention are described below by taking as an example that a group of four types of networks, PBB access, VPLS access, TRILL access, and SPB access, need to communicate with each other.

[0023] In order to describe the embodiments of the present invention more clearly, the concept of "broadcast domain" is introduced, and at least two heterogeneous network accesses can be mapped to the same broadcast domain. Packets in a broadcast domain can be forwarded at Layer 2 directly according to the destination address of the packets, that is, the broadcast domain defines the scope of Layer 2 interworking. The embodiment of the present invention allows multiple broadcast domains to coexist, and different broadcast domains cannot communicate with each other at Layer 2. This embodiment of the present invention uses a broadcast domain identifier (broadcast domain ID) to uniquely identify a broadcast domain.

[0024] In order to realize Layer 2 interw...

Abstract

The invention discloses a method and a device for double layered mutual communication in a heterogeneous network. The method comprises the steps: accessing and mapping at least two heterogeneous networks into a same broadcast domain, mapping each network access to a corresponding access point according to the access types, packaging information and corresponding interfaces, and configuring a corresponding mapping rule; inquiring the mapping rule by a transmitting device when a transmitting list based on an MAC address is generated to obtain an access point corresponding to a message received, and adding the access point to an output interface list corresponding to the transmitting list; inquiring the corresponding transmitting list according to a target MAC address by the transmitting device after receiving a user data message, inquiring the mapping rule according to the access point of the corresponding output interface list to obtain corresponding access type, packaging information and output interface, and transmitting from the output interface according to the access type and packaging information after packaging the user data message correspondingly. According to the invention, double layered mutual communication of the heterogeneous network can be realized.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for Layer 2 intercommunication of heterogeneous networks. Background technique [0002] With the development of Internet technology, a variety of Layer 2 bearer technologies have emerged in carrier networks and data center networks, such as VPLS (Virtual Private LAN Service, virtual LAN service, a type of L2VPN) and PBB in carrier networks. (Provider Backbone Bridging, operator backbone bridge, also known as MAC-IN-MAC, a carrier bearer technology) technology, TRILL (TRansparent Interconnection of Lots of Links, multi-link transparent interconnection protocol for data center networks, A protocol supporting Layer 2 multipath forwarding) and SPB (Shortest Path Bridging, a shortest path bridging protocol, a protocol supporting Layer 2 multipath forwarding) technology. Due to the interconnection needs of multiple sites and multiple heterogeneous network...
