Abstract

A VSM system message transmission apparatus and method are disclosed. The VSM system message transmission apparatus includes: a first GE channel, a second GE channel, a first switching chip, and a second switching chip; the first switching chip is configured to forward an interactive message to a corresponding port of the second switching chip when receiving the interactive message sent by a CPU via the first GE channel, and to send an interactive message to the CPU via the second GE channel when receiving the interactive message sent by the second switching chip via the second GE channel; thesecond switching chip is configured to send an interactive message to a corresponding member equipment port via a VSM channel when receiving the interactive message send by the first switching chip via the second GE channel, and to send an interactive message to a corresponding port of the first switching chip via the second GE channel when receiving the interactive message sent by the member equipment port via the VSM channel.

Description

technical field [0001] The embodiments of this specification relate to the field of network communication technologies, and in particular to a VSM system message transmission device and method. Background technique [0002] VSM (virtual switch matrix, virtual switch matrix) is a new network device virtualization technology, which connects multiple network devices through physical ports to operate as a virtual logical device. Each member device in the VSM system includes a CPU and a switch chip. Between each member device, a VSM channel is obtained through port aggregation of the switch chip, and message transmission is performed through the VSM channel. [0003] In the prior art, the CPU is generally connected to the switch chip through a PCI (Peripheral Component Interconnect, external link) bus. The data is sent to the CPU through the PCI bus for processing. In addition, the CPU also receives data sent by other external devices through the switching chip through the PCI b...
