Service Control Paradigms and Network Architectures

  • Chapter
  • First Online:
Networks and New Services: A Complete Story

Part of the book series: Internet of Things ((ITTCC))

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.

Notes

  1. 1.

    An agent is a program acting on behalf of a person or organization.

  2. 2.

    Actually a double C-S system could provide the functionalities of a MP paradigm. However the difference between the server side and the client one is such that many clients are not capable to host both the client and the server functions.

  3. 3.

    Actually this is another evidence that the expressive power of the C-S paradigm is not sufficient to provide services that do require responsive control on the flow of data. Introducing asynchronous (and invisible to the users) calls between the client and the server is pointing to the need for more capable control mechanisms. Actually those mechanisms are also provided in WebSocket that definitely change the C-S paradigm (in fact the server can use now the socket to notify events and messages to the client).

  4. 4.

    Services in a P2P system can be implemented wherever there is processing and storage power (provided by users), individual peers provide also connectivity that is usable independently from the Operator that is physically supporting it. Services can be deployed and provided by making use of resources that are not necessarily attached to the specific TelCo Network; actually they can be geographical distributed.
