Embodiment Construction

[0073] The present invention provides a method for automatic route selection in a virtual switching domain, the core of which is: firstly configure routing analysis information according to the edge nodes and user information of the DRE in the domain, and configure the routing analysis information according to the edge nodes and adjacent domains of the DRE in the domain The DRE node information configures inter-domain routing information; and then performs automatic route selection according to the calling and called party information, the routing analysis information, the local DRE network topology information and VLAN resource information, and the configured inter-domain routing information.

[0074] Embodiments provided by the present invention, such as image 3 mentioned, including:

[0075] Step 101: Set routing analysis information according to the edge nodes of the DRE in the local domain and user information, and set inter-domain routing information according to the ed...

Abstract

This invention relates to a method for selecting paths automatically in a virtual switch domain including: configuring route analysis information based on the local DRE edge nodes and user information and configuring inter-domain route information based on the local domain DRE edge nodes and adjacent domain DRE node information then selecting routes automatically based on the information of the calling and called, route analysis, network topological information of the local domain DRE, the VLAN resource information and the assigned inter-domain route information, which can select the best service path so as to use the network resources reasonably.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for automatic route selection in a virtual switching domain. Background technique [0002] With the continuous increase of Internet scale, various network services emerge one after another, and advanced multimedia systems emerge in endlessly. Since real-time services are sensitive to characteristics such as network transmission delay and delay jitter, real-time services will be greatly affected when there are high-burst FTP or HTTP services containing image files on the network; on the other hand, Multimedia services occupy a large amount of bandwidth, so it is difficult to obtain reliable transmission of key services that need to be guaranteed by the existing network. Therefore, various QoS technologies emerge as the times require. IETF has proposed many service models and mechanisms to meet the requirements of QoS. [0003] Among them, a variety of portal-based application...
