Abstract
A node controller (30) within a data communication network (22) provides network access for a digital data stream (32). A processor (42) partitions the digital data stream (32) into a constant data rate component (44) having a predictable data rate and a data packet component (46) having an unpredictable data rate. The constant data rate component (44) is then transferred over a first portion (74) of a network data stream (26) reserved for a circuit transmission protocol, and the data packet component (46) is packetized and transferred over a second portion (76) of the network data stream (26) reserved for a packet transmission protocol.
