1. In Service Oriented Networks, the two basic uses of service are:
a) Something of value being provided to and consumed by end-users of communications networks. It may be a specific service, such as Verizon FIOS IPTV Premier or Acme Restaurant Finder, or it may be general, such as VoIP telephony service or emergency services.
b) A function that is performed by software whose output is used by some other entity. It may be, for example, a presence engine, or a routing function, or a number translation capability, or protocol interworking. ‘Service’ may also refer to the software itself.
A service can be turned into a Service Enabler when complemented with appropriate logic and exposure building blocks, so that it can be reused or combined by another application through well-defined functional and operational interfaces.
