Potn service bearing method and system based on generalized optical burst switching

Abstract

The service bearing method and device of the packet-enhanced optical transport network based on generalized optical burst switching provided by the embodiments of the present application, when receiving service data of a synchronous service type, aggregate multiple data frames of such service data into one burst data packets, and generate a burst control packet for one burst data packet, that is, multiple synchronous service data frames correspond to one burst control packet, thereby reducing the number of burst data packets of synchronous service data. The switch control unit in the core node in the network will perform a cross-connection configuration every time it receives a burst control packet, thus reducing the number of times the switch control unit performs cross-connection configurations, thereby reducing the number of cross-connection configurations performed by the switch control unit. The resource overhead required increases the types of services that the packet-enhanced optical transport network can carry without affecting network performance.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a POTN service bearing method and system based on generalized optical burst switching. Background technique [0002] Packet Optical Transport Network (POTN) is a unified transport platform integrating Optical Transport Network (OTN), Time Division Multiplexing (TDM) and packet technology, providing multi-service, Large-capacity, long-distance information carrying mode. POTN has both the packet processing capability of PTN and the large-capacity bandwidth and long-distance transmission characteristics of OTN. It can carry all services with a single form of network, and no longer distinguishes between Synchronous Digital Hierarchy (SDH) and Packet Transport Network , PTN), OTN, realize unified management and maintenance and resource scheduling, and realize network node intensification. [0003] However, based on the existing switching technology, if the POTN equipm...

Problems solved by technology

However, the connectionless and cacheless characteristics of traditional OBS technology have caused OBS technology to face challenges in supporting multiple types of services, especially some connection-oriented services, such as TDM services, optical line, PWE3 services, etc.
