Techniques for oversubscribing edge nodes for virtual private networks

摘要: Techniques for operating a network interface include automatically determining whether communications are terminated over particular attachment circuit on an intermediate node at edge of provider network, whereby sign death (SOD) the is indicated. The switched with virtual private that link layer (VPN) encapsulated in higher protocol. packet-switched network. direct communication to customer outside If it determined there indication SOD, then new action initiated response SOD circuit. These techniques allow automatic logging usage, billing, and fault detection, as well over-subscription resources multiple VPNs.
