A communication system transmits groups of digital communication data from a plurality of sources over a communication network having a bandwidth varying in time. An input receives the communication data. A memory stores for each data group a bandwidth value indicative of a predetermined amount of bandwidth and a priority value indicative of priority. A processor at least estimates the data-carrying ability of at least a portion of the system, identifies the predetermined amount of bandwidth and priority assigned to current data groups presenting data for transmission over the network, identifies the amount of bandwidth requested by the current data groups, and determines eligible current data groups in response to at least the data-carrying ability, the predetermined amount of bandwidth and priority identified for the current data groups, and the amount of bandwidth requested by the current data groups. An output transmits data from the eligible current data groups.
