===Gateways===
To facilitate the sharing of services across domains, Tuxedo provides domain gateways.  A domain gateway allows importing and exporting services from remote domains.  This allows the local domain to see services on remote domains as though they were local services.  The domain gateways are responsible for propagating security and transaction context to the remote domain.  Besides connecting Tuxedo domains together, domain gateways exist for mainframe systems using [[TCP/IP]], IBM's [[Systems Network Architecture]] (SNA), or the [[OSI protocols]], and [[Java Platform, Enterprise Edition]] application servers.  For the mainframe gateways, each system sees the services imported from the remote system as local services and use the local systems infrastructure to interact with those services.  This means that Tuxedo sees a [[CICS]] transaction as a Tuxedo service, and CICS sees a Tuxedo service as a CICS transaction.
