Problems solved by technology

[0006] It can be seen that several S-channels need to be established between the C component (C-component) / S component (S-component) of the original customer bridge and PE in the device, but there is no clear method to establish S-channel

Embodiment Construction

[0047] Generally speaking, the establishment of S-channel between C-component / S-component and PE can be realized by extending LLDP.

[0048] Specifically, the protocol used for PE discovery and S-channel creation in the extended bridge device may be called EDCP (the protocol name is only for convenience of description, and the present invention is not limited to the use of this protocol name). In addition, it is necessary to explain how the EDCP discovers PEs inside the extension bridge, and how to establish the S-channel between the C-component / S-component and the ports of each PE. Usually, the components inside the extension bridge exchange EDCP protocol messages containing their own specific information, and the peer end stores the neighbor information after receiving it and performs related configurations as required.

[0049] It should be noted that the EDCP protocol message needs to carry port information and E-VID corresponding information, such as: the port identificat...

Abstract

The invention discloses a method and a system for realizing S-channel building. In the method of the invention, a directly-connected port expander (PE) which is directly connected with a C-component / S-component announces own port information to the C-component / S-component; the C-component / S-component announces expanded virtual local area network identification E-VID corresponding to each port to the directly-connected PE; and the PE configures a member group of the E-VID according to distributed E-VID. The technology for realizing S-channel building provided by the invention can support S-channel by either the method or the system.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for realizing the establishment of a service virtual local area network identification channel (S-channel). Background technique [0002] A unified data center fabric is a network fabric that combines traditional local area network (LAN) and storage area network (SAN) traffic within the same physical network to reduce architectural complexity and enhance data flow and access. To be effective, traditional Ethernet must be upgraded and provided with additional data center networking features and functions. Therefore, storage protocols must be adapted to run over Ethernet. [0003] The IEEE has defined the term Data Center Bridging (DCB), which is an architectural collection of Ethernet extensions to improve Ethernet networking and data center management. [0004] Currently in the DCB group, a demand for a virtual environment network edge virtual bridging (Edge Virt...
