Abstract
An ALPS tunneling protocol (ATP) is used to transport airline reservation data over ATP virtual circuits extending between branch and data center resources of an air-line reservation internetwork system. The resources include branch and data center routers, along with AX.25/EMTOX virtual circuits, bordering a TCP/IP network cloud of the internetwork system. The ATP protocol includes a set of primitives used to establish ATP virtual circuits for transporting ATP-encapsulated frames between the branch and data center routers. The frames are encapsulated in accordance with an encapsulation technique of the ATP protocol that enables maintenance of airline reservation data frame boundaries over the TCP/IP network and correlation between ATP virtual circuit end-points in the routers.
