摘要： A method for identifying an application service in a BcN(Broadband convergence Network) is provided to be utilized for designing a BcN, analyzing a failure, and creating an application service weather map, and effectively manage the BcN. Transmitted packets are collected, start and destination IP address and port information of each collected packet are obtained, and packets having the common start and destination IP address and port information are grouped(S100,S200,S300). The pre-set number of packets having the same start or destination IP address and port information are sampled in the respective groups, payload data of the sampled packets is obtained, and application services are primarily identified according to a signature or a protocol mapping by using the payload data(S400,S500,S600). Each different weight value is applied to the primarily identified application services, and an application service having the largest value is identified as the final application service in a corresponding group(S700).

摘要： A method for measuring an end-to-end available bandwidth using a time stamp message and a one-way delay time difference in an IP(Internet Protocol) packet network is provided to exactly measure an end-to-end available bandwidth as an origination point and a destination point transmits and receives packets and messages after inserting a new header field next to an IP header. An origination point(201) transmits at least one packet having a specific bit rate to a destination point(203). Receiving the packet, the destination point measures a change in one-way delay time, based on the time stamp message and bit rate contained in the packet. Using the measured one-way delay time, the destination point estimates an available bandwidth, inserts the estimated available bandwidth in the packet, and transmits it to the origination point. Based on the estimated available bandwidth, the origination point adjusts the bit rate of the packet and retransmits it to the destination point.

摘要： A system and a method for identifying a P2P application service are provided to maintain a network safely and effectively by finding an abnormal traffic like a worm virus in managing the network. A method for identifying a P2P application service comprises the following several steps. A flow generator collects IP packets and generates a flow(S200). A port number based identifier identifies a P2P application service on the basis of the port number by using the generated flow(S201). If the P2P application service is identified(S202), an checking unit checks the identified application service(S203). If the application service is not correctly identified(S204) or the P2P application service is not identified in the step S202, a payload based identifier identifies the P2P application service on the basis of the payload(S205). If the P2P application service identified on the basis of the payload(S206) or the identification is checked in the step S204, a SET table generator generates a SET table by using the identified application service flow(S207). A SET table based identifier identifies a P2P application service by using the SET table with respect to a flow not identified via the port number based identification or the payload based identification(S208).
