Abstract: Provided are a method and an apparatus for periodically measuring speech quality in a voice over Internet protocol (VoIP) terminal while a VoIP call between VoIP terminals is in progress. The method comprises: receiving summary information regarding traffic sent from an opposite VoIP terminal; and evaluating speech quality by comparing the summary information with actually received information regarding the traffic sent from the opposite VoIP. Accordingly, each VoIP terminal can precisely evaluate the speech quality periodically and send the evaluation result to each other.

Abstract: A method for managing the network resources of multimedia services in a broadband convergence network is provided to enable a resource authentication control server to collect LSP resources, allocate an available bandwidth to each service, and compare available resources with required resources to determine whether the required resources are available, thereby performing the authentication and control of resources for multi-service applications in an integrated network. A transmission resource controller(108) of a resource authentication control server(106) requires and collects LSP(Label Switched Path) resources set in a network from an MPLS(Multi-Protocol Label Switching) network device(104). A network manager(102) allocates LSP bandwidth resources to each service(118). A service control server(112) requires resource authentication(120). A policy determination unit(110) refers to the transmission resource controller for determining whether resources are available(122). The transmission resource controller searches an LSP set between two routers on the collected LSP resources and determines whether bandwidth resources by service are available(124).

Abstract: A method for processing a signaling message in an MPLS LSP based transmission network and a subscriber network supporting path-coupled signaling is provided to enhance scalability of a network by reducing a load which is added to the transmission network. A interaction supporting system is made up of a transmission network boundary router(120) and a resource management system(130). If a specified terminal(110) of a subscriber network transmits a path-coupled signaling message through a specified path(170), the transmission network boundary router connected to the subscriber network converts the message and transmits the converted message to the resource management system. The resource management system checks up the message to identify the subscriber network where a subscriber terminal(160) is located, a transmission network boundary router(140) connected with the subscriber network, and the resource management system(150). And the resource management system transmits the converted message to the identified resource management system so as to perform the path-coupled signaling on the path(190) between the boundary router and the terminal(160) of a called party.

Abstract: A P2P traffic classifying system and method are provided to satisfy requirements of a network provider who needs to essentially recognize characteristics of a P2P application and a manager who needs to analyze an Internet application and recognize a risk that the application may apply to a network, at an early stage. A traffic detecting unit(110) detects traffic from the Internet(200). An IP address extracting unit(120) extracts information including an IP address from a packet of the detected traffic. A rule management unit(130) generates a rule based on the extracted information and stores/manages it, and applies the rule to the packet transmitted from the traffic detecting unit(110). A file management unit(140) classifies and stores the packet in a storage unit of a file system according to an instruction of the rule management unit(130).
