Abstract

The present invention provides a message cache management method, which includes the following steps: S1, the flow management engine receives the message; S2, the entry cache resource management module performs resource management and message acceptance control on the message; S3, the exit cache The resource management module performs resource management and message admission control on the message; S4, if both the ingress buffer resource management and the egress buffer resource management pass, then store the message in the MMU shared cache; otherwise, refuse to store the message in the MMU shared cache And discard the arriving packets. The invention proposes a cache space virtualization method, improves the shared resource management method, and can evaluate the congestion level in real time and dynamically adjust the resource usage upper limit of each port and flow classification in the shared resource area accordingly.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message buffer management method and system. Background technique [0002] In the prior art, the routing and switching chip structure is as follows: figure 1 As shown, the network switching chip is divided into an uplink packet processing engine, a traffic management engine and a downlink packet processing engine. In the uplink processing engine, the packet is mapped to obtain the internal processing priority of the switch chip according to the external priority field (such as 802.1p, DSCP, etc.) carried in the packet header. After receiving the packet, the traffic management engine obtains the flow classification index number of the packet according to the internal priority mapping. The traffic management engine can then provide differentiated cache resource allocation and management for different applications according to the traffic classification index numbe...
