Embodiment 1
[0034] In order to provide system bandwidth control, Embodiment 1 of the present invention proposes a buffer management method in a switching device of a switching system. The method uses a dynamic sharing method to reasonably allocate traffic in the presence of resource competition. Such as image 3 As shown, the method includes:
[0035] Step S1: Receive request completion signals sent by different target terminals through corresponding input buffers, count the number of request completion signals, and output the count value.
[0036] Wherein, the request completion signal refers to the end data of the request signal sent when the target terminal requests resource data from the source terminal; relatively, the request source signal refers to the start data of the request signal.
[0037] Step S2: Receive the request source signals sent by different target terminals through corresponding input buffers, combine the count value, and randomly encode to obtain a confirmation sig...
Embodiment 2
[0042] Since in existing switching systems, packets block when the condition for the packet to communicate is left behind, the head of the buffer enters a "cannot continue" condition and the packet must wait for one of the leading packets "go ahead" condition, which introduces unnecessary delays and blocks communication. In order to solve the communication blocking problem, the second embodiment of the present invention proposes a buffer management method in the switching equipment of the switching system. order to allow traffic to pass. At this time, if Figure 4 As shown, after step S2, it also includes:
[0043] Step S3: Receive ready-to-receive signals sent by different target terminals through corresponding input buffers according to different data receiving priorities.
[0044] Wherein, the ready-to-receive signal refers to a signal sent by the target terminal to indicate that the corresponding target terminal is ready to receive data from the source terminal.

Embodiment 3
[0051] In order to further reduce communication congestion on the basis of Embodiment 2, Embodiment 3 of the present invention proposes a buffer management method in a switching device of a switching system. The method prioritizes data packets to be sent to a target terminal The division allows delay-sensitive data packets to pass through congested nodes with a higher priority than non-delay-sensitive data packets, and stores data packets with different priorities into corresponding subspaces in the address space corresponding to the corresponding target terminal. This makes it possible to read in priority order when the buffer contains multiple traffic streams. At this time, if Figure 5 As shown, after step S6, it also includes:
[0052] Step S7: Divide the address space of each target device into several subspaces, and give the priority of the data packets in each data element in the source queue.
[0053] Wherein, the address space refers to the address space in the outp...
