Interconnect system of IP communication net and mutual connection method of IP communication net

摘要

P To provide a technology capable of restricting traffic when roaming communication is carried out. PSOLUTION: In an interconnection system of IP communication network and a first terminal 16 of a first network 10 and a second terminal 46 of a second network 40 are subjected to interconnection through networks (20 and 30) equipped with at least one NAT (Network Address Translation) function and ALG (Application Level Gateway) function. In the interconnection system and a path of control packet and a path of media packet in the mutual communication of the first terminal and the second terminal are permitted to be different. The system includes means (22 and 24) for setting a path of media packet so that the media packet passes an optimum path. PCOPYRIGHT: (C)2008 and JPO& INPIT
