Embodiment Construction

[0056] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] Figure 4 The flow chart of the load sharing method in the SPB network provided by the embodiment of the present invention, such as Figure 4 As shown, the specific steps are as follows:

[0058] Step 400: Among the B-MAC addresses configured on the BEB device, select one as the primary B-MAC address, select one or more as the load sharing B-MAC address, and configure and enable the QCN function on each BEB device.

[0059] Step 401: When a BEB exchanges SPB-ISIS protocol packets with other BEBs and establishes a neighbor relationship, it notifies its primary B-MAC address and each load-sharing B-MAC address to other BEBs through the ISIS protocol packets equipment.

[0060] Step 402: The BEB device synchronizes the link state information with each neighboring BEB device. After synchronization, it has all BEB device informat...

Abstract

The invention provides a method and equipment for sharing load in an SPB (Shortest Path Bridging) network. The method comprises the followings: BEB (Backbone Edge Bridge) equipment is provided with a main B-MAC (Backbone-Media Access Control) address and at least one load sharing B-MAC address, a main path and at least one load sharing path are established between the BEB equipment and neighboring BEB equipment; at initial period, flow transmission is performed through the main path between the BEB equipment and the neighboring BEB equipment; and when flow congestion is generated between the BEB equipment and neighboring BEB equipment, partial flow of the BEB equipment to the neighboring BEB equipment is switched on an unused load sharing path between the BEB equipment and the neighboring BEB equipment. The flow transmission efficiency in an SPB network is improved.

Description

technical field [0001] The invention relates to the technical field of Shortest Path Bridging (SPB, Shortest Path Bridging), in particular to a load sharing method and equipment in an SPB network. Background technique [0002] Media Access Control (MAC, Media Access Control)-in-MAC protocol is defined by the Institute of Electrical and Electronics Engineers (IEEE, Institute of Electrical and Electronics Engineers) 802.1ah, also known as the provider backbone bridge (PBB, Provider Backbone Bridge) protocol. As a Layer 2 virtual private network (VPN, Virtual Private Network) technology, it encapsulates the user MAC address in the operator's MAC address through MAC address nesting, thereby isolating different user services. [0003] A network using the MAC-in-MAC protocol is called a provider backbone bridge network (PBBN, Provider Backbone Bridge Network), also called a MAC-in-MAC network. From the user's point of view, PBBN is a Layer 2 switching network, which can establis...
