摘要： A method and apparatus for processing a signal on an intermediate network node at an edge of a provider packet-switched network to support a link-layer virtual private network includes receiving a signal on a particular interface. The particular interface is for a direct communication link to a customer network node outside the provider network. It is determined whether the signal indicates that the particular interface is changing from an inactive state to an active state, whereby the signal is called first sign of life (FSOL). If it is determined that the signal is FSOL, then configuration data is determined for configuring the particular interface for the particular virtual private network. The signal is processed based on the configuration data. These techniques allow a dynamic response to new signals on a customer interface without human intervention by the provider.

摘要： A method and apparatus for configuring a network interface to support a virtual private network includes storing configuration data at a server on a host computer on the provider network. It is determined without human intervention whether conditions are satisfied for sending the configuration data to a particular node at an edge of the provider network without receiving a request message from the particular node. If it is determined that conditions are satisfied, then the configuration data is sent to the particular node to cause the particular node to configure a particular interface for supporting a virtual private network over the provider network based on the configuration data. The particular node is different from the host. These techniques allow changes in configuration data to be pushed to provider edge nodes without human intervention.

摘要： Techniques for configuring a particular network interface on a particular node at an edge of a provider network to support a particular virtual private network include receiving customer input data. The provider network is a packet-switched network and the particular virtual private network is a link layer virtual private network. The customer input data indicates a topology for customer equipment devices outside the provider network on the particular virtual private network, and may include properties for corresponding interfaces that connect the customer equipment devices to the edge nodes. Based on the customer input data, configuration data is determined for configuring the particular interface at the particular node. The particular node is caused to configure the particular interface based on the configuration data without human intervention. Among other effects, these techniques support zero-touch provisioning of virtual private networks.

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

摘要： A client device establishes a first tunnel connection or tunnel, through a public network, with a first gateway of a private network and establishes, through the tunnel connection, a data connection with a destination device within the private network. The first gateway monitors or analyzes the geographic locations of the gateways associated with the private network relative to geographic location of the destination device associated with the data connection. Based upon such the monitoring, the first gateway transmits information to the client device relating to establishment of a second tunnel connection or tunnel with a second gateway of the private network. The client device establishes the second tunnel connection with the second gateway and establishes a data connection with the destination device through the second gateway. By establishing the second tunnel connection with the second gateway, the client device utilizes the bandwidth of the public network to exchange data with the destination device, thereby decreasing data transmission costs to the private network and decreasing private network latency.

摘要： In one embodiment, a method includes receiving a data link layer packet, such as an Ethernet packet, at a local provider edge node in a provider network from a first customer edge node of multiple customer edge nodes connected directly to the local provider edge node. A tunnel data packet for a particular tunneling protocol is generated. The tunnel data packet includes tunnel data that indicates tunnel termination at a different provider edge in the provider network. The tunnel data packet also includes customer identifier data and the data link layer packet. The customer identifier data uniquely indicates a customer associated with the first customer edge node. The tunnel data packet is sent over the provider network.

摘要： Techniques for exchanging point to point protocol (PPP) information among network nodes using an arbitrary network protocol include determining whether a PPP payload includes PPP control data. If so, then an outbound protocol frame is generated with the PPP control data in a payload and with an outbound protocol type field that indicates PPP control data. The outbound protocol frame is sent to a server which uses the PPP control data. The outbound protocol is different from PPP and from PPP over Ethernet (PPPoE) and from PPP over Asynchronous Transfer Mode (ATM) protocol (PPPoA). The outbound protocol may be Ethernet or ATM Adaptation Layer (AAL) or some other protocol. These techniques allow PPP control plane functionality while utilizing IP over Ethernet for the data plane.
