ABSTRACT:
Data packets having different assigned priorities are multiplexed by operating a queue for each different priority of data packet and assembling groups (80) of the data packets for transmission. Each group has two portions. A first portion (90) of the group is populated with data packets selected from one or more of the queues according to a first rule and a second portion (95) of the group is populated with data packets selected from one or more of the queues according to a second rule. Preferably the first portion contains data packets having the highest priority, and the second portion contains a selection of the data packets having a lower a priority. Selection of data packets for the second portion may depend on criteria such as delay experienced and queue length. The size of the first and second portions may be adapted according to delay experienced and queue length.
