Method for access network to realize synthesis business access

Abstract

The invention relates to a broadband access network method for accessing integrated services. The invention includes the following steps: firstly, establishing at least one label switching path (LSP) in broadband access network based on multi-protocol label switching (MPLS); then, MPLS encapsulates the service to be transferred in the broadband access node equipment and transfer in the broadband access network through the LSP. As MPLS is a technology of providing a multi-level connection, the method, which takes MPLS as a private line means for broadband access network networking and traversing core network, can solve the problem faced by broadband access network as integrated services bearer network, thus realizing the bearing of integrated services like IP video, voice, data and private lines (including IP leased line and ATM private line of traditional asynchronous transmission mode, TDM private line and FR private line ).

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing integrated service access in an access network. Background technique [0002] Network operators have been seeking ways to simultaneously carry services such as voice, video, data, and leased lines on the same network to improve network utilization and reduce investment and operating costs. [0003] The IP network has the advantages of high bandwidth efficiency, low cost, high bandwidth, open and flexible services, and ease of use. With the large-scale deployment of broadband access networks, the IP network has gradually become a realistic platform for comprehensive service bearing. In addition to the data services that they mainly carry at the beginning, operators hope to access services such as voice, video, and enterprise private lines through broadband access nodes. In addition to newly deployed IP-based voice and enterprise private line s...

AI Technical Summary

Problems solved by technology

[0019] 1. Survivability: The Ethernet access network of the tree network cannot meet the requirements of service protection; the Ethernet ring network constructed by the RSTP protocol has a protection switching time of seconds, which cannot meet the switching time requirements of high-quality services

[0020] 2. QOS and security: Ethernet forwarding based on MAC address learning cannot meet the security requirements of integrated service bearing in terms of predictable forwarding direction and traffic isolation

In terms of bandwidth planability, it cannot meet the QOS requirements of integrated service bearer

[0021] 3. It is impossible to establish a full network connection across the BAS (or core network edge router) to better ensure the service quality of voice and private line services

[0022] 4. Traditional TDM, ATM, and FR services cannot be carried, and there is no standard method for carrying traditional TDM, ATM, and FR services across the BAS (or core network edge router)

[0023] Therefore, there is currently no access network that can provide integrated services such as voice services, data services, video services, and private line services at a relatively low cost.
