AI Technical Summary

Problems solved by technology

As a result, there is no priority management and bandwidth management mechanism for services at the interface, and the entire ring network does not provide QOS guarantee features
And it is necessary to redesign the networking interface and switching mode, which cannot support the upgrade of the existing ATM switch and support the asynchronous transfer mode ring network
[0006] If the asynchronous transfer mode ring network directly uses the sub-port of the existing ATM service processor for processing, the processing time will be extended, and the bandwidth of the Ring can only reach 1 / 2 of the ATM service processor (ATM Processor) at most.

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] figure 1 The structural representation of the asynchronous transfer mode ring network that the present invention proposes is provided, and it comprises three parts, packet switching end, packet processor and ATM ring network controller ARC, wherein packet switching end and packet processor are ATM switching system usually ARC is the ring network device.

[0025] In the asynchronous transfer mode ring network, there must be an ATM switching device. Before entering the Ring, the processing of the node is performed. According to the characteristics of the business, the data packets that need to enter the Ring are processed and sent to the ARC, which is processed by the ARC and sent to interface A or B. of the loop. Similarly, the data packets coming from the input ends of interfaces A and B are judged by ARC to belong to the node, and then go down to th...

Abstract

The invention consists of: an input end with three channel interface A, B, C, Interface A, B are loop interface, interface C is a local interface; service distributor A, B, C whose input end are corresponding to the input end of interface A, B, C; an output end of three channel interface A, B, C; the service dispatcher A, B, C locate between the service distributor A, B, C and output end of interface A, B, C. The service dispatcher A, B, C separately receives the data package traffic flow from other two distributor and makes dispatcher's control.

Description

technical field [0001] The invention relates to asynchronous transfer mode (ATM) transmission technology, in particular to a controller which can support ATM loop and guarantee service quality. Background technique [0002] The traditional optical transmission network (SDH / SONET) mainly adopts the TDM method, and the load is multiplexed by a fixed-size virtual container, which is more effective in transmitting voice services and point-to-point dedicated line services, but for the rapid growth of data Business and other broadband services, the efficiency of SDH / SONET transmission system is very low. If ATM switches are directly used for interconnection, the price is very expensive, so it is urgent to develop a reasonably priced ATM transmission and access equipment that can effectively utilize bandwidth, that is, asynchronous transfer mode ring network products. [0003] Asynchronous transfer mode ring network (ATM ring) is the product of the combination of ATM technology an...
