Introducing the BEA Tuxedo System

Communication among domains is managed through a set of processes called gateways. The BEA Tuxedo system offers the following types of domain gateways to accommodate different communication protocols:

BEA Tuxedo (TDomains)-Domains provides interoperability between two or more BEA Tuxedo applications through a specially designed TP protocol that flows over network transport protocols such as TCP/IP.
BEA eLink for Mainframe-OSI TP-provides interoperability between BEA Tuxedo applications and other transaction-processing applications that use the OSI TP standard. OSI TP is a protocol for distributed transaction processing defined by the International Standards Organization (ISO).
BEA eLink for Mainframe-SNA-allows BEA Tuxedo clients and servers to operate with clients and servers in an MVS/CICS or MVS/IMS environment in remote SNA domains. It also connects to multiple SNA networks from the local BEA Tuxedo domain.
BEA eLink for Mainframe-TCP/IP for MVS (for CICS)-provides gateway connectivity that makes it possible for non-transactional tasks within BEA Tuxedo regions to access services provided by CICS application programs and vice-versa. It enables a BEA Tuxedo domain to communicate, via the TCP/IP network transport protocol, to a CICS environment. (A BEA Tuxedo domain is the BEA Tuxedo application defined in a single configuration file.)
BEA eLink for Mainframe-TCP/IP for MVS (for IMS)-provides gateway connectivity enabling transparent communications between client and server transactions in an IMS system and a BEA Tuxedo domain, a CICS system, or another IMS system.
BEA TOP END Domain Gateway (TEDG)-provides interoperability between TOP END systems and BEA Tuxedo domains. The TEDG supports fully transactional bidirectional message passing and queueing between TOP END and BEA Tuxedo systems.
