It is disclosed hereby that a switch system comprises a N:M switch circuit, a plurality of layer 2 switches, each comprising a plurality of packet processing channels, and a plurality of network interfaces, each comprising a fixed number of pairs of ports to be directly connected to the same number of devices. The N:M switch is coupled with the N number of the packet processing channels of the layer 2 switches at the N-side and with the M number of the ports of the network interfaces at the M-side. When a packet containing a destination to a receiving device sent by a sending device arrives at the network interface, the N:M switch establishes an electronic connection between an available packet processing channel and a port to which the sending device is connected, the packet passes through to the packet processing channel in which the packet is processed and stored. The N:M switch establishes another connection between the packet processing channel and a new port of the network interface to which the receiving device is connected to, thereby the stored packet passes through to the receiving device to finish a transmission of the packet between the sending device and the receiving device.
