Abstract

The embodiment of the invention discloses a lossless adjustment method of the ODUflex channel bandwidth and an ODUflex channel and relates to the technical field of communication. The lossless adjustment method comprises the steps that according to bandwidth adjustment indication requesting information, a time slot, occupied by an ODUflex frame on the outlet side of each network node on the ODUflex channel, of a high-order optical channel data unit is adjusted; according to speed adjustment instruction information, the speed of ODUflex frame transmission conducted by each network node is adjusted, and the transmission speeds of the network nodes on the ODUflex channel are made to be unified. According to the lossless adjustment method, the time slot that the ODUflex frame on the outlet side of each network node on the ODUflex channel occupies the high-order optical data unit is adjusted, the speed of ODUflex frame transmission conducted by each network node on the ODUflex channel is adjusted, and therefore lossless adjustment of the ODUflex channel bandwidth is achieved.

Description

[0001] This application is a divisional application of the Chinese application with the application number 200980147853.5, the application date is June 9, 2009, and the invention title is "a non-destructive adjustment method for ODUflex channel bandwidth and ODUflex channel". technical field [0002] The invention relates to the field of communication technology, in particular to a method for nondestructively adjusting the bandwidth of an ODUflex channel and the ODUflex channel. Background technique [0003] As the core technology of the next-generation transport network, OTN (Optical transport network) can realize flexible scheduling and management of large-capacity services, and has increasingly become the mainstream technology of the backbone transport network. [0004] With the rapid development of data services, the current OTN system can no longer meet the requirements of directly carrying various services with different rates. In response to this requirement, ITU-T is...
