Abstract: A method for servicing network traffic in a wide area network (WAN) comprising a plurality of network devices is provided. The method is executed by a network device among the plurality of network devices and comprises: receiving a request to transmit the network traffic to a destination network device where the request specifies that the network traffic is to be serviced by a network service; determining, based on the request and using a service-aware virtual topology (SAVT) routing table, a path through the WAN for reaching the network service and a service instance identifier (ID) of the network service; configuring the network traffic to include a service bit indicating whether service is to be performed and instructions specifying the path for reaching the network service; and transmitting, after configuring the network traffic, the network traffic toward the destination device through the at least one network service.

Abstract: Restrictions to control of wireless resources shared openly on a wireless network for playing media are described. At a high-level, advertisement are broadcast for an openly shared resource service are restricted with respect to who, when and where control is permitted. A resource controller app can be implemented on a Wi-Fi controller, on an SDN controller, or as a separate server to intercept advertisements (e.g., service advertisements) being sent for broadcast by an openly shared resource. The advertisements are then transmitted over unicast according to specific parameters concerning specific users, devices, or locations, for example.

Abstract: A method for transmitting network traffic across a wide area network (WAN) from a first site to a second site is provided. The method is executed by a first edge network device at the first site that further includes a second edge network device, and the method includes: receiving the network traffic from a client device at the first site; determining, using ipath characteristics and a classification of the network traffic, that the network traffic should be transmitted by the second edge network device to the second site; forwarding in response to the determination, the network traffic to the second edge network device using a local tunnel over a local area network (LAN) of the first site such that the network traffic is transmitted to the second site by the second edge network device.

Abstract: In general, embodiments relates to a method for creating an on-demand tunnel (ODT) in a network between a first network device and a second network device, the method comprising: storing by the first network device, a a potentially suboptimal path to the second network device, determining that a trigger condition to create the ODT between the first network device and the second network device is satisfied, in response to the determination: transmitting, by the first network device, an ODT signaling packet to the second network device via the potentially suboptimal path, receiving, from the second network device and in response to transmitting the ODT signaling packet, an ODT keepalive by first network device via the ODT, and transmitting, after receiving the ODT keepalive, a second packet to the second network device via the ODT.

Abstract: A method for generating an application-aware virtual topology (AAVT) routing table for a network device among network devices connected via a wide area network is provided. The method is executed by a network controller connected to the network and includes: receiving, from the network devices, path information of the network devices; generating, using the path information, an underlay graph specifying a path topology of the network device; generating, based on the path topology specified in the underlay graph, the AAVT routing table for the network device where the AAVT routing table includes a set of paths; and transmitting, in response to generating the AAVT routing table, the AAVT routing table to the network device to cause the network device to program the set of paths.

Abstract: Systems and methods for load balancing in a network are disclosed. An illustrative method includes receiving network telemetry data corresponding to network paths of a plurality of coexisting multipaths, performing an adaptive load balancing process by determining whether a network path from the plurality of coexisting multipaths is an adequate network path based on the network telemetry data, and in response to determining the network path is an adequate network path, selecting the network path for a network flow.
