Parameter Description
VPI/VCI Data flows are broken up into fixed length cells,
each of which contains a Virtual Path Identifier
(VPI) that identifies the path between two nodes,
and a Virtual Circuit Identifier (VCI) that identifies
the data channel within that virtual path. Each
virtual circuit maintains a constant flow of cells
between the two end points. When there is no data
to transmit, empty cells are sent. And when data
needs to be transmitted, it is immediately inserted
into the cell flows.
