Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0039] figure 2 It is a schematic diagram of the composition of the distributed data communication system of the present invention and the forwarding of multicast messages; see figure 2 , the distributed data communication system of the present invention includes a line card (LPU) for data forwarding, a main control card (MPU) for protocol processing, and a The switch matrix card (SFU) forwarded between cards, the line card, the main control card and the switch matrix card are inserted on the backplane 101 of the system, and interact through the lines of the backplane.
[0040] The general functions of the main control card, switch matrix card, and line card are the same as those of the prior art. The difference between the present invention and the prior art will be described emphatically below.
[0041] In the distributed data ...
