The invention provides a PCIe HBA IOC internal bus network interconnection method and device. The method comprises the steps that TLP interface data is directly transmitted to a first network interface unit of an on-chip bus network through a first PCIe subsystem; the first network interface unit converts the TLP interface data into a network data transmission frame and forwards the network data transmission frame to the routing exchange logic; the routing exchange logic sends the network data transmission frame to a second network interface unit based on routing information contained in the network data transmission frame; and the second network interface unit analyzes the network data transmission frame to obtain TLP interface data and directly forwards the TLP interface data to the second PCIe subsystem. According to the method, the TLP is in direct butt joint with the custom bus network, a transfer bridge of a standard bus interface is not needed any more, the design area of a chip is reduced, operation p
