AppendixA

VPI & VCI

This appendix describes VPI and VCI.

VPI & VCI

ATM is a connection-oriented technology, meaning that it sets up virtual circuits over which end systems
communicate. The terminology for virtual circuits is as follows:

z

 

VC (virtual channel)

 

Logical connections between end stations

z

 

VP (virtual path)

 

A bundle of VCs

Think of a VP as a cable that contains a bundle of wires. The cable connects two points, and wires within
the cable provide individual circuits between the two points. In an ATM cell header, a 

VPI

 (Virtual Path

Identifier) identifies a link formed by a virtual path and a 

VCI

 (Virtual Channel Identifier) identifies a

channel within a virtual path. The 

VPI

 and 

VCI

 are identified and correspond to termination points at ATM

switches as shown. Your telephone company should supply you with these numbers.
