Abstract: A network device may receive a flow having source information corresponding to a first client device and destination information corresponding to a second client device. A tag may then be created by the network device for the flow based upon the source information and the destination information. Next, the network device may encapsulate a packet corresponding to the flow. The packet may be encapsulated with encapsulation information including the created tag. The encapsulated packet may then be routed through a plurality of intermediate network devices in the network. The created tag encapsulated with the packet may identify the packet as being a part of the flow as the packet is routed through the plurality of intermediate network devices.

Abstract: An application switch instantiates two application-side network service instances for the same application. Each network service instance is characterized by a common Internet Protocol (IP) address, a common Open Systems Interconnection (OSI) reference model layer 2 (L2) media access control (MAC) address, and a unique (for the application) supplemental L2 identifier. The application switch maintains a mapping between a {client IP address, client port} tuple and a particular instantiated network service instance based at least in part on the supplemental L2 identifier of a particular one of the instantiated first and second network service instances.

The header of the packet identifies an inner tunnel that is encapsulated within an outer tunnel during transmission of the packet within the network. The device sends the packet with the translated source network address within the header of the packet.

Abstract: A system may provide connectivity service in a multi-tenant network. A first node in the multi-tenant network can receive data packets, each of the data packets identifying one of a plurality of tenant devices. The first node can determine an Internet Protocol (IP) address associated with each of the data packets. The first node can determine a Virtual Local Area Network Identifier (VLAN ID) based on the IP address, the VLAN ID being a unique identifier of a respective one of the tenants. The first node can add the VLAN ID of a corresponding one of the tenants into a header of each of the data packets. The first node can transport the data packets to a second node in the multi-tenant network via a multi-tenant network tunnel protocol.

Abstract: A network device may be configured to provide a gateway between a remote host and a mobile node using multiple interconnection protocols. The network device may include database circuitry configured to query a database for a first or second address of a mobile node using a domain name of the mobile node. The addresses may be associated with different interconnection protocols. The network device may include communication interface circuitry configured to receive a request from a remote host to communicate with the mobile node. The request may include the domain name. The interface circuitry may also be configured to transmit a message indicating the request using the first address, and transmit the second address to the remote host so that the remote host can communicate with the mobile node using the second address. The message may include a command to establish a data bearer through the second address.

Abstract: Techniques are provided for managing network traffic and alleviating network congestion issues in video conference environments. At a video conference bridge device configured to send and receive communications to an endpoint device in a network, one or more video streams are received from the endpoint participating in a video conference. Each of the video streams is classified as a rate adaptive stream or as a non-rate adaptive stream. For video streams classified as rate adaptive streams, the video streams are assigned to a buffer queue for rate adaptive streams. For video streams classified as non-rate adaptive streams, the video streams are assigned to a buffer queue for non-rate adaptive streams.

Abstract: In one embodiment, an electronic device maintains one or more tunnel-based overlays for a communication network. The communication network includes two or more physical provider networks. The device maintains a mapping between a particular application and the one or more overlays for the communication network.

The device causes one or more routers in the communication network to route traffic for the particular application according to the adjusted mapping between the application and the one or more overlays for the communication network.

Abstract: In one embodiment, a device in a network determines one or more network metrics regarding operation of the network. The device determines one or more policy constraints regarding the routing of network traffic through a virtual service platform (VSP).

The VSP usage policy is operable to cause traffic in the network to be routed through a particular VSP that is selected based on the VSP usage policy. The device causes the VSP usage policy to be implemented in the network.
