Broad band cut-in device for supporting multiple service transmission

Abstract

The present invention relates to a supporting multiple service transmission access equipment. Said access equipment features configuring MPLS (multiple protocol label switch) connection management unit in access equipment, said MPLS connection management unit used for establishing access equipment service transmission required label connection of label switch route, and in service transmission process controlling said label connection use. The present invention realizes end to end MPLS network, in the present invention user accessed network edge point capable of sensing service and establishing MPLS connection, entire network processing complexity, supporting TDM, ATM, FE, and ADSL etc service accessing, effective raising network utilization ratio.

Description

Technical field [0001] The present invention relates to the technical field of broadband communication, in particular to a broadband access device supporting multi-service transmission. Background technique [0002] Currently, DSLAM (Digital Subscriber Line Access Multiplexer) broadband access equipment mainly includes: ATMDSLAM (Asynchronous Transfer Mode DSLAM) and IP DSLAM. Among them, ATM DSLAM is a broadband access device with ATM connection switching as the core, and IP DSLAM is a broadband access device with VLAN (virtual local area network) + MAC (media access control) switching as the core. [0003] The existing broadband access equipment can be divided into two types from the equipment form, namely: frame-type broadband access equipment and box-type broadband access equipment. Both types of broadband access equipment include four parts: the main control part, the switching system, the user interface part, and the backplane connection system, such as figure 1 Shown. [...

AI Technical Summary

Problems solved by technology

[0020] The switching system in the broadband access equipment based on the Ethernet architecture uses VLAN+MAC for switching. When a large number of users access, the requirements for the converged Layer 2 network are very high, and the Layer 2 converged network needs to support a large number of MAC+ VLAN address entries, especially after the multi-service network is implemented, each user has multiple service terminals with multiple MAC addresses, which aggravates the requirements of the aggregation network and makes the networking impossible

[0021] Moreover, because broadband access equipment based on Ethernet architecture can only have relatively good compatibility and adaptability to IP-based services, and for TDM access originally supported on traditional ATM DSLAM equipment, ATM access services , due to the inability to process them, these broadband access devices lose their compatibility with existing network services

[0022] In addition, Ethernet-based broadband access equipment is limited by Qos capabilities, and can only achieve priority distinction based on coarse-grained flows, and cannot finely manage service Qos. In future-oriented fine-grained service management and configuration loss of scalability
