Resource allocation using an auto-discovery mechanism for provider-provisioned layer-2 and layer-3 virtual private networks
DCFirst Claim
1. A method for establishing a Virtual Private Network (VPN) tunnel between a first provider edge (PE) device and a second provider edge (PE) device of a Provider-Provisioned VPN (PPVPN) comprising:
- advertising at least one tunnel-based parameter to one or more PE devices over a network backbone using an extension to an auto-discovery protocol, the one or more PE devices including at least one of the first and second PE devices;
determining VPN capability discovery information including the at least one tunnel-based parameter; and
negotiating between the first and second PE devices to automatically establish and configure a VPN tunnel between the first and second PE devices based upon the VPN capability discovery information.

Abstract
A technique for resource distribution using an auto-discovery mechanism for Provider-Provisioned Layer-2 and Layer-3 Virtual Private Networks. In one particular exemplary embodiment, the technique may be realized by a method for establishing a Virtual Private Network (VPN) tunnel between a first provider edge (PE) device and a second (PE) device of a provider-provisioned VPN. The method may comprise advertising at least one tunnel-based parameter to one or more PE devices over a network backbone using an auto-discovery mechanism, the one or more PE devices including at least one of the first and second PE devices. The method further may comprise configuring a VPN tunnel between the first and second PE devices based at least in part on the at least one tunnel-based parameter.

9. In a Provider-Provisioned Virtual Private Network (PPVPN), a system comprising:
-
auto-discovery means for distributing at least one Virtual Private Network (VPN) tunnel-based parameter to at least a first provider edge (PE) device and a second provider edge (PE) device using an extension to an auto-discovery protocol; and tunnel signalling means for determining VPN capability discovery information including the at least one tunnel-based parameter, and negotiating between the first and second PE devices to automatically establish and configure a VPN tunnel between the first and second PE devices based upon the VPN capability discovery information.

14. In a distributed network, a Provider-Provisioned Virtual Private Network (PPVPN) system comprising:
-
a network backbone; a first provider edge (PE) device and a second provider edge (PE) device, each operably connected to the network backbone; an auto-discovery mechanism for distributing at least one VPN tunnel-based parameter to at least the first and second PE devices using an extension to an auto-discovery protocol; and a tunnel signalling mechanism adapted to determine VPN capability discovery information including the at least one tunnel-based parameter, and negotiate between the first and second PE devices to automatically establish and configure a VPN tunnel between the first and second PE devices based upon the VPN capability discovery information. - View Dependent Claims (15, 16, 17, 18)
