Embodiment Construction

[0044] In order to illustrate the technical solutions of the embodiments of the present invention more clearly, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The following descriptions are only some embodiments of the present invention. For those of ordinary skill in the art, Other implementations of the present invention can also be obtained according to these embodiments without any creative effort.

[0045] Embodiment 1 of the present invention provides a method for establishing a data forwarding path in a network. Embodiment 1 of the present invention mainly uses a specific bridge network in Ethernet, for example, a carrier backbone bridge network (PBBN) as an example to illustrate the data forwarding path. The establishment method, but not limited to this, the method is also applicable to networks of other types of structures. Such as figure 1 As shown, the method includes:

Abstract

The invention discloses a method, equipment and a system for establishing data forwarding paths in ethernets so as to improve the ethernet expansibility, fully use the ethernet link resources, avoid the mutual diffusion of route information among a plurality networks when connecting the ethernets and speed up the ethernet convergence, belonging to the filed of the telecommunication technology. The method for establishing the data forwarding paths in the ethernets comprises the step of setting default outlet ends for all non-default outlet ethernet elements according to default outlet ethernet elements in the ethernets so as to make the unknown destination address data frames which are forwarded in the ethernets reach the default outlet ethernet elements through the non-default outlet ethernet elements and the default outlet ends thereof. The invention also discloses a method for connecting ethernets, comprising the following steps: maintaining other bridge forwarding table items in the first ethernet by all bridges of the first ethernet, sending the unknown destination address data frames in the first ethernet to a core ethernet through the default outlet bridges of the first ethernet, and sending the unknown destination address data frames in the first ethernet to a second ethernet by the core ethernet.

Description

technical field [0001] The invention relates to telecommunications Ethernet technology, in particular to a method for establishing a data forwarding path in the Ethernet, a data forwarding method, and an Ethernet interconnection method, equipment and system. Background technique [0002] As a successful local area network (LAN) technology, Ethernet is widely used in many occasions such as enterprise network and home network. In order to use the Ethernet for a metropolitan area transmission network, the International Institute of Electrical and Electronics Engineers (IEEE) has defined a provider backbone bridge (Provider Backbone Bridge, PBB) technology. Moreover, in order to expand the coverage of the Ethernet, the Internet Engineering Task Force (IETF) has proposed a multi-protocol label switching / virtual private LAN switching (MPLS / VPLS) technology. [0003] Among them, PBB technology extends the frame format of Ethernet, supports the nesting of two layers of MAC addresse...
