Technique for implementing an optical/TDM virtual private network
A technique for implementing an optical virtual private network is disclosed. In one particular exemplary embodiment, the technique may be realized by a method comprising the steps of managing at least one client edge-virtual private network at a client edge by a service provider; and supporting a set of client edge-users at each client edge-virtual private network at each client edge wherein each client edge provides at least one virtual private network service to each client edge-user; wherein each client edge determines connectivity associated with each client edge-user and the service provider establishes the connectivity determined by each client edge.
1. A client edge (CE) node for interfacing with a carrier network to implement a client edge virtual private network (CE-VPN), the CE node comprising:
at least one communication interface configured to connect the CE node to a carrier network;
at least one processor coupled to the at least one communication interface; and
at least one storage medium storing instructions executable by the at least one processor, the instructions comprising:
instructions executable by the at least one processor to implement a CE-VPN to provide a virtual private network (VPN) service through the CE-VPN;
instructions executable by the at least one processor to associate a set of client edge users (CE-Users) with the CE-VPN, the set of CE-Users comprising at least one CE-User;
instructions executable by the at least one processor to determine connectivity for each CE-User of the set of CE-Users;
instructions executable to establish the determined connectivity for each CE-User of the set of CE-Users; and
instructions executable by the at least one processor to provide the VPN service to each CE-User of the set of CE-Users.
2. The CE node of claim 1 , wherein the instructions comprise instructions executable by the at least one processor to discover other CE-Users in the set of CE-Users.
3. The CE node of claim 2 , wherein the instructions comprise instructions executable by the at least one processor to process a request from a first CE-User for a connection to a second CE-User.
4. The CE node of claim 3 , wherein the instructions executable by the at least one processor to process the request from the first CE-User for the connection to the second CE-User comprise instructions executable by the at least one processor to establish the connection without intervention from a third party.
5. The CE node of claim 1 , wherein the instructions comprise instructions executable by the at least one processor to provide to a third party membership information associated with at least one of the CE-Users.
6. The CE node of claim 5 , wherein the membership information comprises a VPN identifier.
7. The CE node of claim 5 , wherein the membership information comprises a global unique identifier.
8. The CE node of claim 1 , wherein the instructions comprise instructions executable to request connectivity to another CE node using a private address.
9. The CE node of claim 1 , wherein the instructions comprise instructions executable to request connectivity to another CE node using an address assigned by a transport network.
10. The CE node of claim 1 , wherein the CE node comprises a router.
11. The CE node of claim 1 , wherein the CE node comprises a cross-connect device.
12. The CE node of claim 1 , wherein the CE node comprises a switch.
13. The CE node of claim 1 , wherein the VPN is an optical VPN.
14. A non-transitory storage medium storing instructions for execution by at least one processor of a client edge (CE) node to interface the CE node with a carrier network to implement a client edge virtual private network (CE-VPN) to provide a virtual private network (VPN) service through the CE-VPN, the instructions comprising:
instructions executable by the at least one processor to associate a set of client edge users (CE-Users) with the CE-VPN, the set of CE-Users comprising at least one CE-User;
instructions executable by the at least one processor to determine connectivity for each CE-User of the set of CE-Users;
instructions executable to establish the determined connectivity for each CE-User of the set of CE-Users; and
instructions executable by the at least one processor to provide the VPN service to each CE-User of the set of CE-Users.
15. The medium of claim 14 , wherein the instructions comprise instructions executable by the at least one processor to discover other CE-Users in the set of CE-Users.
16. The medium of claim 15 , wherein the instructions comprise instructions executable by the at least one processor to process a request from a first CE-User for a connection to a second CE-User.
17. The medium of claim 16 , wherein the instructions executable by the at least one processor to process the request from the first CE-User for the connection to the second CE-User comprise instructions executable by the at least one processor to establish the connection without intervention from a third party.
18. The medium of claim 14 , wherein the instructions comprise instructions executable by the at least one processor to provide to a third party membership information associated with at least one of the CE-Users.
19. The medium of claim 18 , wherein the membership information comprises a VPN identifier.
20. The medium of claim 18 , wherein the membership information comprises a global unique identifier.
21. The medium of claim 14 , wherein the instructions comprise instructions executable to request connectivity to another CE node using a private address.
22. The medium of claim 14 , wherein the instructions comprise instructions executable to request connectivity to another CE node using an address assigned by a transport network.
