Abstract:
1. An I/O connection system comprising: an upstream network interface unit, including a plurality of elements distributed on a network, that bridges computers and the network; and a downstream network interface unit, including a plurality of elements distributed on the network, that bridges I/Os and the network, wherein each of said upstream network interface unit means and said downstream network interface unit means has a function of terminating a PCI express (PCIe) bus, a function of a PCI-PCI bridge complying with PCIe standards, and a function of encapsulating a TLP into a packet and tunneling the TLP on the network, and the system incorporates said upstream network interface unit as an upstream PCI-PCI bridge of a multi-root PCI express switch (MR PCIe switch), the network as an internal bus of the MR PCIe switch, and said downstream network interface unit as a set of downstream PCI-PCI bridges of the MR PCIe switch for each of the plurality of I/Os.
