Connection-oriented communication system with communication path re-establishment mechanism
First Claim
1. A connection-oriented communication system, comprising:
- communication means for providing connection-oriented communication paths; and
first communication execution means for making a connection request for requesting a communication port of a connected communication path for replacing a currently used communication path in the communication means;
communication path establishing means for creating the connected communication path and returning one communication port of the connected communication path to the first communication execution means, in response to the connection request made by the first communication execution means; and
second communication execution means for receiving another communication port of the connected communication path from the communication path establishing means, such that mutually communicating programs connected with the first and second communication execution means continue to communicate through said one and another communication ports of the connected communication path replacing the currently used communication path.

Abstract
A connection-oriented communication system capable of realizing the communication path re-establishment automatically, without requiring the programming of the procedures for the re-establishment of the communication path in the mutually communicating programs. The system includes: communication unit for providing connection-oriented communication paths: first communication execution unit for making a connection request for requesting a communication port of a connected communication path in the communication unit: communication path establishing unit for creating the connected communication path and returning one communication port of the connected communication path to the first communication execution unit, in response to the connection request made by the first communication execution unit; and second communication execution unit for receiving another communication port of the connected communication path from the communication path establishing unit, such that the first and second communication execution units communicate through that one and another communication ports of the connected communication path.

14. A method of connection-oriented communication, comprising the steps of:
-
(a) making a connection request for requesting a communication port of a connected communication path for replacing a currently used communication path from a first communication execution means; (b) creating the connected communication path and returning on communication portion of the connected communication path to the first communication execution means, at a communication path establishing means, in response to the connection request made by the first communication execution means; (c) receiving another communication port of the connected communication path from the communication path establishing means at a second communication execution means; and (d) continuing a communication between mutually communication programs connected with the first and second communication execution means through said one and another communication ports of the connected communication path replacing the currently used communication path. - View Dependent Claims (15, 16, 17, 18, 19)
