Abstract
Provided are a method and apparatus for sending and receiving a multiframe, a communication device, and a communication network system. The method includes: determining a multiframe identifier used for identifying a multiframe number according to a number of timeslots of a physical layer, where the multiframe number is the number of frames constituting one multiframe; and sending the multiframe to a receiving end, where the multiframe carries the multiframe identifier. Further provided is a computer storage medium.
Claims4
A method for sending a multiframe, comprising:
- sending a multiframe to a receiving end, wherein a multiframe identifier is carried in the multiframe and a multiframe number is identified by the multiframe identifier, the multiframe number is a number of frames constituting the multiframe, identifier values of the multiframe identifier are sequentially carried in preset positions of overhead blocks of respective frames constituting the multiframe, and the number of the identifier values of the multiframe identifier is the same as the multiframe number;
- in a case where an interface bandwidth speed of the physical layer is 25 Gbit/s, the number of timeslots is five, the multiframe number is eight, and the identifier values of the multiframe identifier are four consecutive “0″s and four consecutive “1″s in sequence;
- wherein each of the preset positions is an Overhead Multiframe Indicator (OMF) field of respective one of the overhead blocks in a Flexible Ethernet (FlexE) protocol, a multiframe boundary is determined according to the identifier values of the multiframe identifier, and the multiframe boundary is used to determine start and end positions of each multiframe;
- wherein whether the multiframe identifier is correctly received according to the number of the identifier values of the multiframe identifier and a receiving sequence.
