PURPOSE: An HSSF(High Speed Switching Fabric) in an AICPS(Advanced Information Communication Processing System) is provided to accept mutual traffics in n numbers of communication networks by an HSSA(High Speed Switching Assembly) through two HBUSs(High Speed common BUSs) and two MBUSs(Management BUSs) in a load sharing method. CONSTITUTION: An HSSF(70) is comprised of two HBUSs(71), 2n numbers of HSCAs(High Speed Circuit Assemblies)(72), and 2n numbers of HSNAs(High Speed Network Adapters)(73). The HBUSs(71) control traffics in n numbers of communication networks executed through two HBUSs(HBUSa and HBUSb) and two MBUSs(MBUSa and MBUSb) in a load sharing method. Between the HBUSs(71), a DCC(Duplication Communication Channel) to control the traffics in the load sharing method is connected in serial. The HSCAs(72) respectively connected to the HBUSs(71) execute data input and output with the HBUSs(71) and n numbers of NASs(Network Access Subsystems)(80). The HSNAs(73) connect the NASs(80) and the HSCAs(72). Two HSNAs are embedded every NAS(80). Each NAS(80) comprises an SPA(Service Processing Assembly)(81) having an interface function to connect with each communication network.
