Embodiment Construction
[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0040] see figure 1 and Figure 6 , introduce the following specific operation steps of the flow control method of the present invention based on the input cross-point cache fast packet switching network:
[0041] Step 1, the input data packet of each input terminal is written into the corresponding output virtual queue VOQ in real time according to the destination port address, waiting to be read by the output scheduling module of the input terminal.
[0042] Step 2: The output scheduling module at the input terminal schedules the data packets in the output virtual queue VOQ according to the scheduling rules, reads the data packets from the VOQ in real time, and writes them into the cross-point buffer in the switching switch. This step includes the following op...

Provided is a flow control method based on an input intersection cache fast packet switched network. An operation method comprises the steps that input data packets of each input end are written in corresponding virtual output queue VOQ in real time according to addresses of a destination end, an output scheduler module of the input end reads data packets from the VOQ in real time according to scheduling disciplines and writes the data packets in an intersection cache CP of an interchange switch, then an output scheduler module of the output end reads and sends data packets in the CP corresponding to the output end in real time according to the scheduling disciplines, when the data packets of the cache of the CP change, the CP sends status update information to the corresponding input end and the corresponding output end in real time, the output end and the input end update stored status values of themselves in real time respectively according to the status update information, and meanwhile the output scheduler module of the input end and the output scheduler module of the output end carry out scheduling on the data packets respectively according to the updated status values to complete transmission of the corresponding data packets.
Description
technical field [0001] The invention relates to a flow control method of a fast packet switching network based on an input cross-point cache, and belongs to the technical field of fast packet switching. Background technique [0002] Traditional packet switching technology was successfully developed in the late 1960s to early 1970s. The transmission medium used at that time was mainly copper wire (including coaxial cable and twisted pair cable), with low transmission rate and high transmission bit error rate, so the bottleneck of network performance was the transmission link, not the switch. [0003] After decades of development, the main transmission medium of the link has become optical fiber, its transmission rate is as high as several Gbits, and the transmission bit error rate is as low as 10 -9 the following. The bottleneck of network performance is no longer the transmission link, but the node switch. This drives people to study fast packet switching technology. [...
