A control system and method for reducing the amount of power consumption of a communication network is provided. The amount of traffic usage and power consumption of communication equipment in the communication network is collected and energy efficiency of the communication equipment is calculated. An operation of the communication equipment and a communication path or routing of the communication network are controlled according to the calculated energy efficiency. Therefore, an operation of unnecessary communication equipment is controlled, thereby reducing the power consumption of the communication network.

Provided is a distributed and asynchronous implicit token carrier sense multiple access/collision avoidance (CSMA/CA) protocol guaranteeing quality of service for both real time and non-real time traffic. The implicit token CSMA/CA protocol allocates a band in an entire bandwidth to voice traffic and allows the remaining bands to be used for data traffic. The implicit token CSMA/CA protocol includes applying a token passing protocol to transmit voice traffic in real time by having a band in an entire bandwidth allocated using a predetermined data frame and applying a CSMA/CA mechanism to transmit data traffic in non-real time by employing remaining bands not allocated to the voice traffic using another predetermined data frame.

A method and system for processing billing of including QoS information are provided. In the method, a call is initiated by transmitting/receiving packets directly to/from an opponent terminal after signaling with the opponent terminal using a session initiation protocol through the signaling server. Then, QoS of the call is measured while communicating with the opponent terminal. A billing process is performed of including the QoS measuring result by transmitting the QoS measuring result to the signaling server after the call established to the opponent terminal is terminated.

Provided are an apparatus and method of selecting a label switched path (LSP) in a network management system. The apparatus comprises a status analyzing unit which analyzes and digitizes performance information, fault occurrence, and fault history of a link in order to convert the performance information, fault occurrence, and fault history into standardized values, a link weight managing unit which determines link weight values using values obtained by adding and subtracting reference values, calculated using a predetermined weight calculation algorithm on second constraints that corresponds to qualitative information related to performance analysis of a path required by an administrative network policy, to and from the standardized values of the status analyzing unit, and an LSP selecting unit which prepares a path list by using a method of executing a predetermined background task by appointing a source and a destination from among all nodes in the administrative network, selects a path, from among paths on the path list, that satisfies first constraints which corresponds to objective information related to a path selection required by the administrative network policy, and, when there are several selected paths, selects a path that minimizes expense using the link weight values. Using the apparatus, the optimum path according to the administrative network policy can be selected.

In an apparatus and method of selecting a label switched path (LSP) in a network management system, a status analyzing unit analyzes and digitizes performance information, fault occurrence, and fault history of a link. A link weight managing unit which determines link weight values using a predetermined weight calculation algorithm on second constraints that corresponds to qualitative information related to performance analysis of a path. An LSP selecting unit selects a path, from among paths on a path list, that satisfies first constraints which corresponds to objective information related to a path selection required by the administrative network policy, and, when there are several selected paths, selects a path that minimizes expense using the link weight values.
