Abstract:
1. A computer network emulation wall and emulation system comprising: two or more emulation computer systems of at least two distinct types; a network able to deliver datagrams to said two or more emulation computer systems through said emulation wall; and wherein two or more of said two or more emulation computer systems provide emulation responses of multiple emulated computer systems at multiple addresses; each emulation computer system providing emulation responses of emulated computers appropriate to said emulation computer system's type; and further comprising: receiving a response at an inside of said emulation wall from said emulation subnetwork; translating a response emulation original address indication to a response proxy address indication; passing said datagram into said network from said emulation subnetwork while translating said response proxy address indication back to a response original address indication; wherein said passing comprises: receiving said datagram at a first network gateway; translating said original address indication of said datagram into a proxy address indication at said first network gateway; routing said datagram with said proxy address indication to a second network gateway; translating said proxy address indication of said datagram into said emulation original address indication at said second network gateway; and forwarding said datagram with said emulation original address indication to said emulation subnetwork.
