Embodiment Construction

[0058] A switch stacking system, a slave device, a switch chip and a method for processing protocol packets provided by the present invention will be described in more detail below with reference to the drawings and embodiments.

[0059] like figure 2 As shown, the embodiment of the present invention provides a switch chip 20, which is applied to a slave device of a switch stack system, including an encapsulation (ENCAP) module 21 and a stack port 22;

[0060] ENCAP Module 21 for:

[0061] Encapsulate the remote processor (RemoteCPU, RCPU) header for the received protocol message to be processed by the CPU of the main device in the stacking system; the RCPU header includes the Layer 2 Ethernet protocol L2 header and the protocol message originally sent Data Center Bridge (DCB) information of the CPU of the master device; among them, the L2 header includes the destination MAC address used internally and the MAC address of the CPU of the slave device; the DCB information inclu...

Abstract

An embodiment of the invention discloses an interchanger stacking system, a slave unit, a switching chip and a method for processing a protocol message. In the scheme, an ENCAP module which is a hardware module in the switching chip is independently used for packaging a protocol message which is about to be processed by a CPU of main equipment. Compared with a method of packaging the protocol message by forwarding the protocol message to a CPU of a slave unit in the prior art, the method not only consumes shorter time in a packaging process, but also simplifies a forwarding process, only the switching chip is utilized, the hardware forwarding speed is high, protocol convergence time of the stacking system is shortened greatly, the protocol message processing efficiency is improved, and the packet loss amount in a protocol switching process is reduced. In addition, DCB information, which is up-supplied to a CPU of a main unit, of the protocol message is packaged at one step in a RCPU head, and the information, which is up-supplied to the CPU of the main unit, of the protocol message received from a device is consistent to the information, which is up-supplied to the CPU of a stand-alone interchanger when the interchanger is in a stand-alone state.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a switch stacking system, a slave device, a switch chip and a method for processing protocol messages. Background technique [0002] With the rapid development of information technology and the rapid expansion of the network scale, the number of switch interfaces planned in the previous network is not enough to meet the needs of network applications. At this time, the switch stacking technology emerges as the times require. The switch stacking technology uses stacking cables to connect several fixed switches together to increase the port density and bandwidth of the switch, and realize high-speed interconnection and unified management of the switches. Logically speaking, they belong to the same device, as long as you log in to Any one of the switches can manage and configure all the switches in the stack, which is very convenient for users, just like managing a stan...
