Service control paradigms and network architectures

Abstract

Telcos’ viewpoint is “Network is King”. Webcos’ viewpoint is “Service is King”—the web client and its services are the center points. However, it is not easy to define what “service” is: a bunch of resource; collection of tasks; particular interactions and semantics; or all the above. By exploring the concepts of service, we can see how services and their definitions evolce, and how their gravity center shifts to unfamiliar zones. The service control is shifting from client–server interaction mode to more open but perplexing peer-to-peer mode. This has a knock-on transforming effect on service structure, message channeling, parallel processing, etc.
