Embodiment

[0058] The present invention will be further described below in conjunction with embodiment.

[0059] Logical function block class name and identification number involved in the present invention are as shown in table 1:

[0060] Table 1 Logic function block class name and identification number

[0061]

[0062]

[0063] figure 2 It uses decomposed logic function blocks and synthesized logic function blocks to realize a data channel that can handle a large number of parallel data packets. figure 2 In , one path classifies IPv4 packets and performs metering at the same time, while the time-to-live (TTL) field of IPv4 packets in the other path is decremented accordingly. The specific implementation of its modules is as follows:

[0064] 1) Decompose the specific implementation of logic function blocks

[0065] 1.1) Decompose the input and output of the logic function block

[0066] The decomposed logic function block has a unique input port, and the input content can ...

Abstract

The invention discloses a data packet flooding parallel processing method in a forwarding and control separation system. In the method, copies of data packets are sent to a plurality of logical function blocks for performing parallel processing, specifically, the copies can be sent to paths in a manner of physical copying, frequent copying can also be avoided through pointer operation, and here, a problem of protection of a pointer among multiple tasks needs to be considered. According to the invention, the data packet flooding parallel processing method in the forwarding and control separation system is used for processing data, speed of processing the data packets is improved greatly, moreover, the system has high extendibility, mature technology and low cost, is very suitable for being generalized and used in large scale, and is convenient for increase of traffic.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data packet flooding parallel processing method in a forwarding and control separation system. Background technique [0002] With the rapid expansion of computer network application fields, new features and new requirements are constantly emerging and changing, which requires that the new generation of network equipment should be flexible enough to quickly respond to new services and new needs; The equipment should have enough openness, so that users can flexibly combine according to the open resources to provide different network demand services; it is required that the new generation of network equipment should have sufficient modularity, and be standardized through standardization organizations, so that each Modules can be independently researched and developed by different manufacturers, and can be organically combined into a whole through building blocks. Thi...
