Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments. In the following description, well-known functions and constructions are not described in detail since they would obscure the invention with unnecessary detail.

[0021] Such as figure 1 As shown, the present invention provides a filtering and splitting device supporting multi-service functions, including: a management unit 1 , a rule policy library unit 2 , a classification matching engine 3 , a service label processing engine 4 , and a convergence switching engine 5 .

[0022] Management unit 1: Provide an interface for the user to formulate rules and policies corresponding to various businesses, and output the formulated rules and policies to the rules and policies library unit 2.

[0023] Specifically, the management unit 1 provides different users with good reading and writing and management interfaces independent of each other, and users establish rules and policie...

Abstract

The invention relates to a filtering and shunting device and a method supporting a multi-service function. The method comprises the following steps of: matching input original data packets with regular policy library subunits established by different users one by one to form match results; processing the match results to form result labels, and establishing a mapping table among the result labels and output ports; and adding the result labels to the heads of the original data packets, obtaining the output ports according to the result labels and the mapping table, and sending the original data packets to users from the output ports. The shunting and filtering functions of a plurality of services share the processing resources in the same input unit and device, a plurality of sets of filtering and shunting policies are supported in a set of filtering and shunting devices, are completely independent, and do not interfered one another, and the requirement of the multi-service function is effectively solved.

Description

technical field [0001] The invention relates to a filtering and splitting of data packets, in particular to a filtering and splitting device and method supporting multi-service functions. Background technique [0002] In recent years, the construction and development of my country's backbone network and metropolitan area network have been very rapid, and the overall scale is also quite large. The bandwidth of almost all regional backbone networks has reached 10G (Gigabit, gigabit), and the bandwidth of some backbone networks It has been upgraded to 40G, and the total export bandwidth has reached the capacity of hundreds of G in large cities and provincial cities, and some super-large cities have reached the capacity of T (Terabit, Gigabit). Various broadband services based on network infrastructure are also booming. Various broadband services and the accompanying security services make the filtering and diverting devices suitable for high-bandwidth and large-traffic a key ele...
