Method of and apparatus for reconfiguring protocol used by application program

An apparatus for reconfiguring a protocol used by an application program, the apparatus comprising:

• an analyzer implemented by a processor and configured to obtain requirement information of application programs and to analyze the requirement information of the application programs;
• a protocol engine implemented by the processor and configured to determine protocol configuration information comprising a reconfigured protocol used by the application programs and an operating parameter of the reconfigured protocol based on an analysis result obtained by the analyzer;
• a protocol implementer implemented by the processor and configured to determine, based on the protocol information, a connection relationship of a component module, among component modules, to implement the reconfigured protocol;
• and
• a reconfigurable protocol stack comprising a memory configured to store component modules,
• wherein
• in order to reconfigure the protocol in an active mode, the determining of the connection relationship comprises
• 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;
• and
• in order to realize the reconfigured protocol in a passive mode, the determining of the connection relationship comprises
• generating information to implement the reconfigured protocol in a target device based on the protocol configuration information by referring to a node state database configured to store a list of protocols currently available to the target device and an operating parameter of a protocol currently implemented by the target device, and by referring to the connection relationship, and
• transmitting, to the target device, the information to implement the reconfigured protocol in the target device.

A method of reconfiguring a protocol used by an application program of application programs, the method comprising:

• determining whether an optimal protocol used by the application programs is the optimal protocol;
• determining, upon requirement information of the application program changing, an optimal value of an operating parameter of the optimal protocol based on the changed requirement information of the application programs and system information obtained from a protocol layer,
• wherein the requirement information comprises latency information and reliability information;
• and
• in response to a current protocol of the application programs not being the optimal protocol, reconfiguring the current protocol used by the application program to be the optimal protocol using a component module missing from the current protocol used by the application program and a component module of the current protocol used by the application program, and setting a value of the operating parameter of the optimal protocol to be an optimal value of the optimal protocol according to which the current protocol is reconfigured as the optimal protocol,
• wherein the determining of the optimal value of the operating parameter comprises
• determining the optimal value of the operating parameter based on an energy function of the operating parameter, such that the energy function is minimized based on the latency information and the reliability information.
