Network fast forwarding module and network fast forwarding achieving method

Abstract

The invention provides a network fast forwarding module and a network fast forwarding achieving method. The achieving method includes the steps of initializing the network fast forwarding module, registering in each linux network subsystem, enabling the network fast forwarding module to obtain and cache network forwarding rules which are issued by a linux network protocol stack, generating a fast forwarding rule cache table when various types of network data flow is initiatively forwarded by the linux network protocol stack, matching the network data flow with the fast forwarding rule cache table after the network data flow is received from network cards again, and directly sending out the network data flow from the corresponding network card if corresponding fast forwarding rules exist, otherwise, sending the network data flow back to the linux network protocol stack to be processed. According to the network fast forwarding module and the network fast forwarding achieving method, bridging and routing forwarding are supported, the network forwarding procedure is simplified, CPU resource consumption is reduced, forwarding delayed time is shortened, and the network forwarding handling capacity is greatly improved.

Description

technical field [0001] The present invention relates to the field of network communication terminals, in particular to a network fast forwarding module applied to customer end equipment (CPE for short) and a method for implementing network fast forwarding based on Linux. Background technique [0002] With the continuous maturity of Internet technology, Internet applications are becoming more and more extensive, and users have higher requirements for network bandwidth and network equipment performance. With the construction of "fiber-in-copper-out" network deployment by fixed network operators, the network access bandwidth has been increased from a few Mbps to 100Mbps or even 1Gbps. In terms of link bandwidth, it can fully meet the needs of users for high-speed data transmission, high-definition video playback, and low latency. VOIP and other application requirements, but user terminal network equipment has become the bottleneck of network forwarding throughput. [0003] As ...

AI Technical Summary

Problems solved by technology

[0004] At present, the client device usually forwards network data packets through the Linux network protocol stack. The network forwarding process is complex, consumes a lot of cpu resources, and there is a large forwarding delay and small forwarding throughput. Therefore, it is necessary to forward this method to improve
