Abstract: 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).
