Claim:
1. An interface controller (PEIC) in a peripheral component interconnect express (PCIE) switching network, the PEIC comprising: a peripheral component interconnect (PCI) to PCI bridge (P2P) module, configured to receive a first transaction layer packet (TLP) from a root complex (RC) or an endpoint device (EP), and forward the first TLP to a reliable TLP transmission (RTT) module for processing; the RTT module configured to search a corresponding address forwarding table or ID forwarding table according to a type of the TLP, obtain a destination PEIC number corresponding to the first TLP so as to determine sending links of active and standby PCIE switching units corresponding to the TLP, and send the first TLP to the active and standby PCIE switching units through the sending links at a same time, so that a destination PEIC of the first TLP selectively receives the first TLP forwarded by the active and standby PCIE switching units and sends the first TLP to a destination EP or a destination RC of the first TLP; and wherein the destination PEIC of the first TLP and the PEIC connect with the active and standby PCIE switching units.
