I/O CONNECTION SYSTEM AND I/O CONNECTION METHOD

摘要

Upstream network interfaces (2-1 to 2-N) and downstream network interfaces (5-1 to 5-N) are provided with upstream PCI-PCI bridge functions and downstream PCI-PCI bridge functions, respectively. These network interfaces (2-1 to 2-N, 5-1 to 5-N) and a network (3) are built in a system as a single multi-route PCI express switch. The network (3) carries out transaction layer packet (TLP) tunneling between the upstream network interfaces (2-1 to 2-N) and the downstream network interfaces (5-1 to 5-N) or between the downstream network interfaces (5-1 to 5-N) themselves. This can connect a plurality of computers with a plurality of I/O devices in a large-scale dispersion scheme without changing software, root complexes and I/O devices.
