Embodiment Construction

[0011] The traffic balance processing method of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] The traffic load balancing processing method of the present invention realizes a traffic load balancing technical scheme in which multiple processors process network traffic in parallel in a network device.

[0013] In the whole system design, first of all, it is necessary to analyze the network bandwidth that the system actually needs to handle; according to the asymmetry of the uplink and downlink traffic in the actual network; secondly, in the design, it is necessary to ensure that the uplink and downlink traffic flow is symmetrical in the system, so as to firstly balance the uplink and downlink Then, in the design, use TCP connection for traffic classification, and use this category to forward packets to different network processors for deep packet analysis, so as to further ensure th...

Abstract

The invention discloses a traffic load balancing processing method, which needs to estimate the bandwidth of a system, determines the number of network processors according to the actual utilized bandwidth, uses one network processor for distribution processing and one network processor for convergence processing in uplink and downlink directions respectively, and needs to perform symmetrical processing to uplink and downlink traffic to balance loads of uplink and downlink simultaneously, wherein the distribution processing is to adopt the TCP connection to perform classification processing and analysis on messages, different connections are marked with different categories, one of the categories is extracted for deep packet inspection analysis at the same time, and other categories are forwarded to a switching chip by using different interfaces/ports respectively and are forwarded to other network processors through the switching chip. The convergence processing is used for converging messages of an output port and performing the speed limitation and statistics of the port after the convergence. The method has the advantages that data processed by the network processors can not be overlapped and repeated, and the processing capacity of a system is high.

Description

technical field [0001] The invention relates to a method, in particular to a traffic load balancing processing method in which a plurality of network processors are used in a communication device to jointly process network traffic. Background technique [0002] When a network device provides the Deep Packet Inspection (DPI) function, its forwarding performance will vary depending on the processing depth of the packet. When a single processor cannot achieve system performance when processing DPI, in order to ensure that packets will not be lost when passing through the system, the system will use random sampling for DPI processing on the traffic, and the other will use direct forwarding. Therefore, the system will inevitably have certain deviations in packet detection and statistics. Contents of the invention [0003] In view of the above problems, the main purpose of the present invention is to provide a balancing method for quasi-processing traffic load. [0004] In ord...
