Abstract: In one embodiment, a method for the prioritized transmission of messages includes monitoring a network link of a mobile device to determine performance characteristics of the network link, establishing a network association between the mobile device and a routing network node, receiving a connection request from an application that is directed to a connection between the mobile device and a destination server, determining a relative priority of the connection, mapping the connection to a stream of the network association that is associated with the relative priority of the connection and identifies the destination server, and transmitting messages for the stream to the routing network node interlaced with messages of other streams of the network association based on the performance characteristics of the network link and the relative priority associated with the stream in comparison to relative priorities associated with the other streams of the network association.

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: In one embodiment, a network controller receives data indicative of one or more traffic requirements for network traffic. The network controller maps the data indicative of the one or more traffic requirements into a network policy. The network controller causes installation of the network policy onto one or more networking devices. The one or more networking devices are configured to route the network traffic based on the network policy. The network controller receives feedback regarding the installed network policy. The network controller adjusts the network policy based on the received feedback.

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: 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, a device in a network identifies a translated source network address for a tunnel source of a tunnel-in-tunnel packet. The device includes the translated source network address within a header of the packet. 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: 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 device generates a VSP usage policy based on the one or more network metrics and on the one or more policy constraints. 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.

Abstract: Systems and methods provide for provisioning a dynamic intent-based firewall. A network controller can generate a master route table for network segments reachable from edge network devices managed by the controller. The controller can receive zone definition information mapping the network segments into zones and Zone-based Firewall (ZFW) policies to apply to traffic between a source and destination zone specified by each ZFW policy. The controller can evaluate a ZFW policy to determine first edge network devices that can reach first network segments mapped to the source zone specified by the ZFW policy, second edge network devices that can reach second network segments mapped to the destination zone specified by the ZFW policy, and routing information (from the route table) between the first network segments, the first and second edge network devices, and the second network segments. The controller can transmit the routing information to the edge network devices.
