Abstract

A method of reconfiguring a protocol used by an application program includes determining an optimal protocol used by the application program and an optimal value of an operating parameter of the optimal protocol based on requirement information of the application program and system information obtained from a protocol layer; and when a current protocol used by the application program is not the optimal protocol, reconfiguring the current protocol used by the application program to the optimal protocol using at least one component module missing from the current protocol used by the application program and at least component module of the current protocol used by the application program, and setting a value of the operating parameter of the optimal protocol to the optimal value of the operating parameter of the optimal protocol.

wherein the determining of the protocol configuration information comprises referring to the protocol database to determine, as the reconfigured protocol and the operating parameter of the reconfigured protocol, one of the plurality of protocols and the operating parameter of the one protocol that are mapped to the requirement information of the application program.

6. The method of claim 1, further comprising:

generating information associated with the connection relationship based on the protocol configuration information; and

implementing the reconfigured protocol using the information associated with the connection relationship.
