Embodiment Construction

[0024] The basic idea of ​​the present invention is: use three-level two-layer Ethernet exchange to realize the switching problem of Ethernet data link, use dynamic MAC address, static MAC address, the combination of dynamic and static MAC address, make redundant backup management, link Road monitoring becomes reliable and convenient.

[0025] One, the present invention adopts a layer-2 Ethernet-based switching to realize the above functions.

[0026] Referring to Fig. 1, the present invention, that is, a data link seamless switching system based on Ethernet switching, has a switching network based on a backplane 101 in the center, and has two switching boards 102 and 103, a master and a backup, in a double-star structure. The other four are service boards, namely the source board 104 and the destination board 105, and their spare boards 106 and 107. Each service board has two network ports connected to two switching boards respectively. Of course, in the actual system There ...

Abstract

A seamless switching-over system of data link based on Ethernet exchange comprises two layers of Ethernet exchange chip, dynamic MAC address for realizing data transmission, static MAC address for realizing real time monitor on data link in operation system and dynamic-static MAC address for carrying out fault- positioning of data link in operation system.

Description

technical field [0001] The invention relates to data link switching technology based on Ethernet switching, in particular to a seamless switching system and method thereof. Background technique [0002] Motherboard-based communication architectures were once widely adopted, but as systems have grown in power and configuration flexibility, and driven by a desire to improve mean time to repair and facilitate system upgrades, The development based on the passive backplane structure has gradually become the mainstream of the communication architecture. [0003] The communication architecture based on the passive backplane makes the upgrade and backup of the system more flexible. Passive backplanes involve a backplane communication problem. In the past few years, the CompactPCI (Compact PCI, Compact Peripheral Component Interconnect) specification has been quite mature as a backplane communication. And is exploring a new platform to carry the next generation of communication a...
