An apparatus for and a method of establishing a connection between a source and destination node using multiple parallel paths. To establish a connection, bandwidth capacity on one or more parallel paths are aggregated and combined to form a route having a bandwidth larger than any single path. A technique similar to inverse multiplexing is used at the source end to split the cell stream into multiple parallel paths. At the destination end, the parallel multiple cell streams are inverse demultiplexed and the multiple cell streams combined into a single cell stream. The parallel routes are established by building parallel VCCs for the same call via the network. The ATM signaling process at the source and destination nodes is modified to accommodate multiple VCCs. In addition, the hardware at each source and destination node is configured to perform the inverse and inverse demultiplexing. Further, the control software at the source and destination nodes is modified to implement the call handling required of such a multiple VCC call, including setup, tear down, error handling, etc.
