Abstract
The model of internet protocols presently available includes four layers, i.e., physical layer, network layer, transport layer and application layer; an application control layer is inserted between the transport layer and the application layer for controlling service usable at each combination of address assigned to a server and port number so that the server can offer push-type service to clients with the assistance of the application control layer.
Claims7
An information supply system comprising:
- a hardware including at least one server assigned an address, at least one client and a communication network connected to said at least one server and said at least one client;
- and
- a protocol model including a physical layer, a network layer on said physical layer, a transport layer on said network layer having plural ports selectively assigned to sorts of push-type service, an application control layer on said transport layer managing applications for said sorts of push-type service at said address and maintaining pieces of server information and pieces of client information and an application layer on said application control layer for maintaining said applications, and established in said hardware for communication between said at least one server and said at least one client, said physical layer, said network layer, said transport layer and said application layer having definitions identical with those given to corresponding layers in an internet protocol model so that said sorts of push-type services are transferred between said at least one server and said application layer and between said application layer and said client.
A method for supplying a push-type service, comprising the steps of:
- a) preparing a tool for communication between at least one user and at least one provider assigned an address through a protocol model including a physical layer, a network layer on said physical layer, a transport layer on said network layer having plural ports selectively assigned to sorts of service, an application control layer on said transport layer managing applications for said sorts of service at said address and maintaining pieces of server information and pieces of client information and an application layer on said application control layer maintaining said applications so as to offer an interface to said at least one user and said at least one provider;
- b) fetching one of said pieces of server information representative of sorts of push-type service assigned certain ports from said application control layer by said at least one user;
- c) selecting at least one sort of push-type service by said at least one user;
- d) requesting said at least one provider to offer said at least one sort of push-type service;
- e) maintaining one of said pieces of client information representative of said at lest one sort of push-type service in said application control layer,
- f) establishing a certain kind of environment for said at least one sort of push-type service in a client computer of said user and a server computer of said provider;
- and
- g) starting said at least one sort of push-type service.
