Claims
- 1. A method for relocating a network subnet to a remote location, comprising:
allocating a block of routable network addresses for use in a relocated network subnet at the remote location; establishing a link from the network subnet to the relocated network subnet; and configuring one or more services at the relocated network subnet.
- 2. The method of claim 1 wherein the link comprises a tunnel.
- 3. The method of claim 1 wherein the routable network addresses comprise static IP addresses.
- 4. The method of claim 1 wherein the routable network addresses are contiguous.
- 5. The method of claim 1 where the allocating a block of routable network addresses is performed by a lease broker.
- 6. The method of claim 1 where the tunnel is configured to traverse a mechanism that encumbers communication.
- 7. The method of claim 6 wherein the mechanism that encumbers communication comprises a NAT.
- 8. The method of claim 1 wherein the one or more services comprises a routing configuration at the relocated network subnet for enabling communications over the tunnel.
- 9. The method of claim 1 wherein the one or more services comprises a DNS server.
- 10. The method of claim 1 wherein the one or more services comprises a DHCP server.
- 11. The method of claim 1 wherein the one or more services comprises a mail server.
- 12. The method of claim 1 wherein the tunnel is configured to automatically reconnect in response to a change in an address associated with one of the components of the tunnel.
- 13. A system for subnet relocation, comprising:
an anchor router coupled to a network; a tether router; a remote subnet coupled to the tether router, the subnet comprising a plurality of nodes, the nodes corresponding to a block of routable network addresses; and a link between the anchor router and the tether router.
- 14. The system of claim 13 wherein the link comprises one or more tunnels.
- 15. The system of claim 14 wherein the tunnel is configured to transmit packets comprising an encapsulation protocol.
- 16. The system of claim 14, wherein the tunnel is configured to traverse a mechanism that encumbers communication.
- 17. The system of claim 16, wherein the mechanism comprises a NAT.
- 18. The system of claim 13, wherein the block of routable network addresses is allocated to a user by a lease broker.
- 19. A computing apparatus for establishing a remote subnet, comprising:
a tether router; and a processor configured to establish a tunnel from the tether router to an anchor router.
- 20. The apparatus of claim 19, wherein a block of addresses are allocated to a user, the block of addresses corresponding to the remote subnet, the tether router for coupling to the remote subnet.
- 21. The apparatus of claim 19 wherein the processor is further configured to traverse a mechanism that encumbers communication.
- 22. The apparatus of claim 21 wherein the mechanism comprises a NAT.
- 23. The apparatus of claim 19, wherein the processor is configured to establish the tunnel such that the tunnel automatically reconnects in response to an event that causes a temporary disconnection of the tunnel.
- 24. The apparatus of claim 23 wherein a heartbeat signal is periodically emitted across the tunnel.
