Structure of network processing unit in communication equipment and its operating method

Abstract

The invention discloses a structure of network processing unit, comprising: a central processing unit, an optical fiber processing unit and a relay processing unit. Wherein, said optical fiber processing unit is connected to the central processing unit or optical fiber processing unit via the optical fiber, and said relay processing unit is connected to the central processing unit or the optical fiber processing unit via the relay. The inventive operations comprise: the central processing unit obtain the ends and the network operation according to the service; the central processing unit confirms the co-processing father unit which is most near to the end and confirms the path information according to the network topology structure; the central processing unit transmits the network operation command to the nearest co-processing father unit; the nearest co-processing father unit receives the network operation command to be processed according to path information. The inventive structure utilizes the tree topology structure and the classified processing mechanism on the network operation process to cancel the limitation of cascade number and reduce the load of central processing unit.

Description

technical field [0001] The invention relates to a network communication technology, in particular to a structure of a network processing unit in a communication device and an operation method thereof. Background technique [0002] In the prior art, optical fibers are usually used for cascading network processing units to achieve high-speed, large-capacity network operation and processing. As shown in FIG. 1 , the topology of processing units cascaded through optical fibers is usually a star structure. The structure of the network processing unit includes: multiple sub-processing units 102 and a central processing unit 101 , and the multiple sub-processing units 102 are all connected to the central processing unit 101 . The sub-processing unit 102 is a fiber-level processing unit or a relay-level processing unit. [0003] In the above-mentioned network structure, all network operations are processed by the central processing unit 101, and network operations generally includ...

Problems solved by technology

However, in the network with the above structure, due to the limited number of interfaces, the central processing unit 101 can only cascade a limited number of sub-processing units 102, thereby limiting the amount of user access

On the other hand, all network operations, such as: endpoint analysis, network time slot selection algorithms are concentrated in the central processing unit 101 and controlled by the central processing unit 101, which will cause a performance bottleneck, thereby reducing the performance of the entire network system
