Patent ID: 7415552

Claim:
A keyboard video mouse (KVM) switch for a plurality of local and remote computers to share a plurality of local manipulating devices, the KVM switch comprising: a plurality of first interfaces adapted for connecting to the local manipulating devices to receive a plurality of local electrical signals, wherein local electrical signals from different first interfaces are for manipulating different local or remote computers; a plurality of second interfaces adapted for connecting to the local computers; a packet encoding device, which generates at least one network packet having a plurality of data sections, at least some data sections of a same network packet corresponding to the local electrical signals received by different ones of the first interfaces destined for different remote computers; a network device adapted for communicating with a network device of another KVM switch using a network protocol in order to transmit the network packet and to receive a network packet transmitted from said another KVM switch; a packet decoding device adapted for obtaining at least one remote electrical signal from the network packet of said another KVM switch; and a switch device adapted for transmitting the local and remote electrical signals to the second interfaces and the packet encoding device according to a path selection setting.
