Resource allocation using an auto-discovery mechanism for provider-provisioned layer-2 and layer-3 Virtual Private Networks
First Claim
1. 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 (PPVPN) comprising:
- 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; and
configuring a VPN tunnel between the first and second PE devices based at least in part on the at least one tunnel-based parameter.

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.

11. 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 and second provider edge (PE) devices; and
tunnel signalling means for configuring a VPN tunnel over a network backbone between the first and second PE devices based at least in part on the at least one tunnel-based parameter. - View Dependent Claims (12, 13, 14, 15, 16)
