Abstract:
1. A method for communication, comprising: encapsulating multiple data packets, which carry data and have respective drop precedence (DP) values selected from a range of possible DP values, to produce a concatenated frame of a transport protocol; assigning a composite drop precedence (CDP) value from the range to the concatenated frame using a pseudo-random assignment function that depends on a distribution of the DP values of the data packets in the concatenated frame, and is defined such that a likelihood of assigning a certain CDP value from the range is proportional to a relative amount of the data in the concatenated frame, which is carried by the data packets whose DP value equals the certain CDP value; and transporting the concatenated frame through a communication network using the transport protocol, in accordance with the pseudo-randomly assigned CDP value.
