LOSSLESS ADJUSTMENT METHOD OF ODUFLEX CHANNEL BANDWIDTH AND ODUFLEX CHANNEL

摘要

The embodiments of the present invention relate to the field of communications technologies, and disclose a lossless adjustment method of ODUflex channel bandwidth and an ODUflex channel. The lossless adjustment method includes: respectively adjusting, according to bandwidth adjustment indication request information, a time slot occupied by an ODUflex frame in a higher order optical channel data unit at an egress side of each network node on an ODUflex channel; and adjusting, according to rate adjustment indication information, a transmission rate of the ODUflex frame of each network node on the ODUflex channel, to enable the transmission rate of each network node on the ODUflex channel to be unified. The embodiments of the present invention achieve the lossless adjustment of ODUflex channel bandwidth by respectively adjusting a time slot occupied by an ODUflex frame in a Higher Order Optical Channel Data Unit at an egress side of each network node on an ODUflex channel, and adjusting a transmission rate of an ODUflex frame of each network node on the ODUflex channel.
