Patent ID: 7305605

Claim:
An information-processing apparatus for converting information generated by an information generation unit into packets to be transmitted to a network and for receiving packets from said network, said information-processing apparatus comprising: a means for performing a TCP/IP conversion process to convert information generated by said information generation unit into a TCP/IP packet group to be transmitted to said network; a management unit for managing as to whether or not a transmission partner is a target of an FEC (Forward Error Correction) communication, managing FEC redundancies each provided for a transmission partner connected to said network, and holding a correspondence relationship associating each transmission partner and a corresponding FEC redundancy; an encoding unit for carrying out an FEC encoding process on said TCP/IP packet group, which has been subjected to said TCP/IP conversion process, by retrieving and applying an FEC redundancy held in said management unit for its corresponding transmission partner identified in the TCP/IP packet group; and a decoding unit for carrying out an FEC decoding process on a packet group received from said network; wherein said management unit has a table stored in a memory, an iSCSI packet group is managed corresponding to the transmission partner, and each FEC redundancy said table is directly related to a state of packet loss determined for said transmission partner for which said FEC redundancy is associated in said table.
