Abstract

The present invention provides a realizing method of multi-service node in T-MPLS optical transmission network. The transmitting process and receiving process to a plurality of business data (TDM, Ethernet service, etc) are realized. In the transmitting process, the multi-service data are firstly adapted and adjusted to T-MPLS frame. The data frame is controlled to transmit the number and length of array through dynamic management of scheduling method. Finally the multi-service data are transmitted by an optical transmitting module. In the transmitting process, the received data frame is processed through a scheduling method for determining to transmit again or receive and reduce to multi-service data. The system is designed with a network management interface which is used for alarming information report and routing information upgrade. Simultaneously, the system is reserved with a novel service interface which can flexibly and conveniently add new service style for T-MPLS network transmission. The method provided by the invention can conveniently provide queue scheduling of multi-service data and has the advantages of low system time delay, flexible and high-efficient resource utilization, etc.

Description

[0001] Field [0002] The invention belongs to the multi-service access technology based on the T-MPLS optical transmission network, and specifically relates to a realization method for adapting various services to the T-MPLS network. Background technique [0003] Transport MPLS (Transport MPLS, T-MPLS) is developed on the basis of traditional IP mechanism-based transport technology. It is an MPLS-based connection-oriented packet transport technology. Its rich functions support a high degree of technical coordination and interoperability with the IP / MPLS layer. It can realize efficient and reliable transmission of packet services, and is a cost-optimized carrier-class packet transmission network. [0004] Under the development trend of accelerating multi-service integration and continuous introduction of new services, it is no longer feasible to deploy different devices for each service. The network unit with high flexibility can support not only traditional services such as...
