摘要： Embodiments of the present invention disclose a method for sending a code block data stream, including: adding m first data frames carrying the code block data stream to n physical layer data frames on an Ethernet physical interface, identifying a location of the first code block of each first data frame in the m first data frames by using an alignment marker of a physical layer data frame in the n physical layer data frames, and sending the n physical layer data frames that carry the m first data frames of the code block data stream, where m and n are integers greater than or equal to 1. According to the foregoing technical solution, there is no need to perform framing search in the first data frame, so as to improve efficiency in performing framing in the first data frame, reduce an overhead bit of the first data frame, and reduce system design complexity.

摘要： In order to measure the latency of a particular transport service from end to end, a method of measuring the latency of a transport connection between a first network node (NT) and a second network node (N2) is provided, which makes use of a virtual concatenation function with a buffer (B) to compensate the differential delay between members in a received virtual concatenation group. In particular, the first network node (NT) creates a virtual concatenation group which has as members at least two multiplexing units (VC4_1 VC4_2). A first of the two (VC4_1) is used as a reference for the latency measurement. The second (VC4_2) is sent to the second network node (N2), where it is looped back to said first network node (NT). The first network node (N1), by using its buffer (B) available for re-aligning members of a virtual concatenation group, determines a latency difference between the first and second multiplexing units (VC4_1, VC4_2).
