40、f information that is used for service routing (e.g., service identity, service address). service: A set of functions provided by software or a system, usually accessible through an application programming interface (API). The service publishes its description information to a service directory and
41、registers to a service registry before providing the service functionality. 1The IEEE Standards Dictionary: Glossary of Terms & Definitions is available at http:/shop.ieee.org/.
