A method implemented in an access node (AN) including receiving a packet for a service on a connection between a subscriber and a service provider or service provider network (SP), replacing a Virtual Local Area Network (VLAN) tag for the subscriber in the packet with a Q-in-Q label that matches a Media Access Control (MAC) address for a residential gateway (RG) in the packet when the packet is received from the RG, wherein the Q-in-Q label comprises a Customer VLAN (C-VLAN) tag that identifies the subscriber and a Service-VLAN (S-VLAN) tag that identifies the SP, and replacing the Q-in-Q label in the packet with a VLAN tag for the subscriber that matches the MAC address for the RG in the packet when the packet is received from the SP.

A machine has a bus, an input port connected to the bus to receive inbound network traffic, an output port connected to the bus to convey outbound network traffic and a processor complex connected to the bus. The processor complex is configured as a pipeline with individual processor cores assigned individual network traffic processing tasks. The pipeline includes a first set of processor cores to construct network traffic trees characterizing the inbound network traffic and the outbound network traffic. Each network traffic tree characterizes traffic type and traffic rate. A second set of processor cores enforces network traffic policies utilizing the network traffic trees. The network traffic policies apply traffic rate control by traffic type for the inbound network traffic and the outbound network traffic.

In some implementations, a first network device may encode Internet Protocol version 4 (IPv4) network layer reachability information (NLRI) using Internet Protocol version 6 (IPv6) next hop encoding to generate encoded IPv4 NLRI. The first network device may include information indicating border gateway protocol (BGP) labeled unicast (BGP-LU) in the encoded IPv4 NLRI. The first network device may advertise the encoded IPv4 NLRI. The first network device may establish a communication session with a second network device, wherein the communication session is established via an IPv6 core network. The first network device may forward, via the communication session, one or more IPv4 packets using the encoded IPv4 NLRI.

Systems, methods and computer-readable storage media are provided for provisioning network inter-connections and extensions to computing infrastructure. In one embodiment, a system can receive a request from a client to establish a network connection between a private network and a remote network, the request including a selection of a virtual network residing at the private network; establish a transit connection between the virtual network and an exchange port established in association with the private network; establish a first network connection between the exchange port and an intermediary cross connect network; establish a second network connection between the intermediary cross connect network and the remote network; and extend a virtual local area network (VLAN) connected to the virtual network of the client at the private network to the remote network via the network connection, the network connection comprising the first network connection and the second network connection.

In general, techniques are described for using virtual local area networks (VLANs) to facilitate packet forwarding between wireless endpoint devices attached to a wireless local area network (WLAN) access network and one or more mobile gateways providing access to packet data network services. For example, a wireless access gateway includes an upstream interface for a mobility tunnel to a mobile gateway of a mobile service provider network and a downstream interface for a WLAN access network. The wireless access gateway receives a packet from the mobile gateway by the upstream interface. The wireless access gateway determines, based at least on the mobility tunnel, a VLAN of the WLAN access network that is uniquely associated in the wireless access gateway with a combination of the APN associated with the mobility tunnel and the mobile gateway. The wireless access gateway then forwards, to a wireless endpoint device, the packet on the VLAN.

A packet transmission method includes a first virtual extensible local area network tunnel endpoint (VTEP) receiving a first packet from a first host and sending a second packet to a third VTEP based on a first IP address corresponding to the first host, where the second packet is obtained by the first VTEP by encapsulating the first packet, where the first host is multi-homed to a second VTEP and the first VTEP, where the second VTEP is configured to send a packet from the first host to the third VTEP based on a second Internet Protocol (IP) address corresponding to the first host, and where the first IP address is the same as the second IP address.

The present disclosure provides a connection status detection method for a controller area network (CAN) bus network access unit. The method includes: determining, for a to-be-detected port of the CAN bus network access unit if the to-be-detected port receives, in a first scanning period, a second scanning period, a third scanning period, and a fourth scanning period that are consecutive, a message notifying an identifier of the CAN bus network access unit, a bus number being 1, and a port number being 1, that the to-be-detected port is connected to a straight-line CAN bus network access unit, and recording the identifier of the CAN bus network access unit, wherein the to-be-detected port is connected to a first port of the straight-line CAN bus network access unit, and the first port of the straight-line CAN bus network access unit is a logical entry.

Aspects of the subject disclosure may include, for example, obtaining traffic that is conveyed at least in part within a private cloud network, based on the obtaining, identifying characteristics of the traffic, and based on the identifying of the characteristics of the traffic, causing at least one action to be performed within the private cloud network. Other embodiments are disclosed.

Methods and systems for flexible nodal layer 3 overlay of layer 2 traffic is described. A network includes an access device for receiving layer 2 traffic from user devices, a packet inspection device for inspecting the layer 2 traffic, and a layer 3 tunnel instantiation device for encapsulating the layer 2 traffic into layer 3 traffic. The layer 3 tunnel instantiation device provides a first tunnel endpoint for a layer 3 tunnel, which is connected to a second tunnel endpoint instantiated at a network gateway. The layer 3 tunnel instantiation device establishes a moveable demarcation between a layer 2 domain and a layer 3 domain with respect to the packet inspection device, where the access device and the packet inspection device operate in the layer 2 domain. The layer 3 traffic is transmitted over the layer 3 tunnel.

A management device includes: an acquisition unit that acquires change information from which a change in an operational state of one or more functional units included in an onboard network is discernible, and from which a change in a state of use of a transmission path in the onboard network by the functional units is discernible; and a setting change unit that performs setting change to change settings for the onboard network based on the change information acquired by the acquisition unit.
