Abstract: Disclosed are a packet transmission apparatus and so on that can suppress transmission delays caused by packet integrations and that can perform the transmissions over a broad band. The packet transmission apparatus includes: a packet extraction means that searches for and extracts, from a buffer for sorting and accumulating packets for respective destinations, the packets for the respective destinations and that, if a plurality of packets addressed to an identical destination have been accumulated in the buffer, extracts the plurality of packets from the buffer; and an encapsulation means that encapsulates the packets, which have been extracted by the packet extraction means, into a single packet for each destination.

Abstract: An information processing device that are capable of continuing access to an I/O device by operational computers even when a failure has occurred in a management computer is provided.A virtualization bridge (300) includes a monitoring unit (307) and a backup control unit (308). The virtualization bridge (300) provides operational computers (200) with virtual functions of an I/O device (400). The monitoring unit (307) detects failures in a management computer (100). The backup control unit (308) generates backup management information (341) on the basis of packets transmitted and received between the management computer (100) and the I/O device (400), and, when a failure in the management computer (100) is detected by the monitoring unit (307), controls the I/O device 400 on the basis of the backup management information (341) in place of the management computer (100).
