FastPacket Adaptation to ATM

A specialized adaptation of particular interest to users of Cisco equipment is the adaptation of IPX
switch FastPackets to ATM cells. A large number of narrowband IPX switch networks currently in
existence efficiently carry voice, video, data, and Frame Relay. A means must be provided to allow
these networks to grow by providing a migration path to broadband.
Because FastPackets are already a form of cell relay, the adaptation of FastPackets to ATM cells is
relatively simple.

Where Used
IGX switch to IGX switch connections over
networks using ATM switches that switch on
VPI only. VPI is manually programmed by
user. Terminating switch converts VCI address
to FastPacket address.
IGX switch to IGX switch connections over
networks using ATM switches that switch
where all routing is manually programmed by
user, both VPI and VCI.
