Abstract:
In a node controller within a data communication network, said node controller including a first in, first out (FIFO) buffer for receiving a digital data stream and a processor responsive to said FIFO buffer, said digital data stream having a composite data rate, a method for providing network access to said digital data stream, said method comprising the steps of:(a) outputting data samples representative of said digital data stream from said FIFO buffer;(b) partitioning said data samples into a constant data rate component having a predictable data rate and a data packet component having an unpredictable data rate, said partitioning step being performed by said processor;(c) forming data packets from said data packet component of said data samples;(d) transferring said constant data rate component over said network using a circuit transmission protocol; and(e) transferring said data packets over said network using a packet transmission protocol.
