Abstract

The present application provides a data packet processing method and device, the method comprising: receiving a data packet sent by each port among multiple ports; according to the header information of the data packet sent by each port, buffering the data packet in the In the storage space; if it is judged that the first storage space can be adjusted, expand the first storage space, and continue to use the first storage space to cache the data packets sent by the corresponding port; if it is judged that the first storage space cannot be adjusted In this case, the port corresponding to the first storage space is prevented from continuing to send data packets; according to the priority of the storage space that caches the data packets sent by each port, each port in the multiple ports is sent in order of priority from high to low. packets sent to the server to cause the server to process packets sent from each of the multiple ports. In this way, the data packets of each port can be prevented from interfering with each other.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data packet processing method and device. Background technique [0002] The Avalon bus has two interfaces, Avalon-MM (memory map) and Avalon-ST (stream). Among them, the Avalon-MM type interface signals are divided into control signals and data signals, and read and write data through addresses. The Avalon-ST interface is a one-way point-to-point high-speed interface, which is mainly aimed at the transmission of high-speed data streams and reduces the bottleneck in data stream processing. When the network port transmits data to the server host through the Avalon_st interface, it needs to be cached through the buffer space (First in first out, FIFO). [0003] For a single-port network port, a common FIFO can meet the requirements. But for multi-port network ports (data packets come from multiple ports, and the port numbers are different), the amount of da...
