System and method for processing access network

Abstract

The invention discloses a system and a method for processing an access network. The technical scheme is characterized by comprising an access module, a switching module and a business processing module, wherein when the system is used for two layers of business, the access module forwards a message from a user side to the switching module for analyzing the two layers of business, and then the message is forwarded to an upper-layer network; when the system is applied to more than three layer of business, the access module analyzes the message from the user side to generate a user side forwarding message, and then the user side forwarding message is send to the switching module; the user side forwarding message is forwarded to the business processing module by the switching module; and the message is sent to the upper-layer network after the message is performed to more than three layer of business processing. According to the realization of the technical scheme of the embodiment of theinvention, the traditional optical line terminal system is smoothly updated.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to an access network processing system and method. Background technique [0002] An OLT (Optical Line Terminal, Optical Line Terminal) device is a terminal device used to connect to an optical fiber trunk line. With the development of the network, the demand for end-user bandwidth is also increasing, which requires OLT equipment to have higher bandwidth processing capabilities, and to be able to achieve fine-grained control of user traffic and classification. At the same time, from the perspective of cost saving, operators hope to reduce the cost of network construction and operation and maintenance, reduce the level of the entire telecommunications network, and improve the location of OLT equipment so that it can be connected with BRAS (Broadband Remote Access Server, broadband remote access server ) are directly connected, and even replace the positions of...

AI Technical Summary

Problems solved by technology

[0006] Since the fully centralized processing OLT equipment concentrates processing, forwarding, and control on one switching processing module, the processing capability of the switching processing module is extremely high, and it is impossible to complete the L2 / L3 and The above processing needs

Although the fully distributed processing structure has strong business processing capabilities and can adapt to the needs of large bandwidth and high performance, the fully distributed architecture is not compatible with the existing fully centralized system architecture, and the system cannot be upgraded smoothly. New equipment can only be introduced to re-network. Increased huge investment costs for operators
