Embodiment Construction

[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] With the continuous vigorous development of data services, the new service form requires not only to support the transmission of large-capacity data services, but also must be able to support its flexible scheduling requirements. The solution is to add a data channel (ODUk) switching plane on the basis of the PTN packet switching plane to reduce the high cost and power consumption caused by scheduling large-capacity services through the packet switching plane; The data channel (ODUk) is used for scheduling; where the service traffic needs to be landed, the aggregation or distribution between the packet and the data channel (ODUk) is performed. Small granular services are processed by the packet function, and large granular services are directly processed by data channel (ODUk) or optical channel (OCh).

Abstract

The invention discloses a rapid configuration method and system for transport network tunnels a mobile POTN (Packet enhanced Optical Transport Network), and relates to the technical field of service configuration in the mobile POTN. The method comprises the steps of automatically searching an optimum data channel and a set of optimum optical channels according to a source node and a destination node appointed by a user, optical fiber connection conditions in and between the nodes, and analysis of resource occupation conditions, and finishing path configuration of an optical transport network; configuring circuit basic attributes of the tunnels, and finishing binding services of a packet transport network through analysis of carrying conditions in the data channels of a service layer; downloading configured node information in the tunnels to a device, and finishing interconnection of configuration and service of the transport network tunnels of the POTN. According to the method and the system, the optical channels and the data channels of the service layer, and the client layer tunnels can be configured rapidly, smartly and flexibly, the service configuration efficiency is greatly improved, and the user experience is better.

Description

technical field [0001] The invention relates to the technical field of service configuration in mobile POTN (Packet enhanced Optical Transport Network, packet enhanced optical transport network), specifically a method and system for fast configuration of tunnels in the mobile POTN transport network. Background technique [0002] With the continuous vigorous development of data services, emerging services such as 4G, IPTV, and broadband access have been deployed on a large scale, and data traffic is showing explosive growth. OTN (Optical Transport Network, Optical Transport Network) equipment based on TDM Time Division Multiplex (Time Division Multiplex) data channel (ODUk) crossover can no longer meet the transmission requirements of data packet services cost-effectively, and the evolution of the packetization capability of OTN equipment is inevitable. Packet Enhanced Optical Transport Network (POTN), as the main technology of next-generation multi-service bearer OTN network...
