ALPS

The Airline Product Set (ALPS) is a tunneling mechanism that transports airline protocol data across a

TCP/IP network to a mainframe. ALPS provides connectivity between agent set control units (ASCUs)

and a mainframe host that runs the airline reservation system.

Figure 104 shows the basic ALPS topology and the protocols implemented in the feature. Three major

components provide the end-to-end transportation of airline protocol traffic across the network: the

P1024B Airline Control (ALC) or P1024C (UTS) protocol, the TCP/IP-based MATIP protocol

conversion, and the TCP/IP access to the mainframe.
