Abstract: Techniques described herein can perform per-queue network performance measurement mapping, in which per-queue network performance measurements are determined and then mapped back to service level agreement (SLA) classes assigned to use the queues. Network traffic associated with an SLA class can be processed through an assigned router queue. Wide area network (WAN) as well as local performance measurements from the assigned queue can be combined to determine a combined performance measurement associated with the assigned queue. The combined performance measurement can then be mapped or otherwise associated with the SLA class. Similarly, combined performance measurements can be determined for other router queues and mapped or otherwise associated with other SLA classes.

Abstract: This disclosure describes techniques for improving routing policy awareness in a network. The method includes detecting, by a controller, an application initiated for use at an edge node of a network. Then, generating, by an analytics engine coupled to the controller, analytical data of traffic flow at the edge node of the network wherein the traffic flow is in accordance with a routing policy for routing traffic associated with the application. Further, routing of the traffic through a path from one or more paths configured at the edge node that is in accordance with at least a Service Level Agreement (SLA) for traffic flow. Also, in response to an SLA violation during routing of the traffic, causing an action, by the controller, of routing traffic flow through another path that is in accordance with at least the SLA for traffic flow based on analytical data received of the traffic flow.

Abstract: This disclosure describes techniques for detecting and monitoring paths in a network. The techniques include causing a source node to generate probe packets to traverse a multi-protocol label switching (MPLS) network, for instance. In some examples, the probe packets include entropy values that correspond to individual equal-cost multi-path (ECMP) paths of the network. The probe packets may be received at an SDN controller from a sink node after traversing the network. Analysis of the probe packets allow path discovery and mapping of the entropy values to ECMP paths. The mapping of discovered paths may be used for optimization of network monitoring activities, including second subsequent probe packets over particular ECMP paths based on the mapped entropy values.

Abstract: Described herein are devices, systems, methods, and processes for improving retransmissions in wireless communication networks by distinguishing between temporal interference and longer-term radio frequency (RF) condition issues. The fact that the access point (AP) does not usually move may be leveraged, and a machine learning process can be utilized to learn and adapt to the RF conditions in the cell. The AP records various parameters for each frame received from client devices and uses this data to build a pairwise temporal matrix. Machine learning models are trained using these parameters, enabling the AP to compute the likely efficient set of modulation and coding schemes (MCSs) at each static position and along moving positions. The AP can then adapt its MCS accordingly for the downlink traffic and provide the client device with recommended MCSs for upcoming uplink transmissions. Accordingly, the retry count at the client devices can be reduced.

Abstract: Systems, methods, and computer-readable media for performing threat remediation through a switch fabric of a virtualized network environment. Data traffic passing into a virtualized network environment including a plurality of virtual machines running on a switch fabric is monitored. A network threat introduced through at a least a portion of the data traffic is identified at the switch fabric. One or more remedial measures are performed in the network environment based on the identification of the network threat in the virtualized network environment.

Abstract: In one embodiment, a supervisory service for a network obtains quality of experience metrics for application sessions of an online application. The supervisory service maps the application sessions to paths that traverse a plurality of autonomous systems. The supervisory service identifies, based in part on the quality of experience metrics, a particular autonomous system from the plurality of autonomous systems associated with a decreased quality of experience for the online application. The supervisory service causes application traffic for the online application to avoid the particular autonomous system.

Abstract: The present disclosure is directed to systems and methods for container security using a hopping mechanism. Methods include the steps of selecting a first virtual container associated with one or more software processes; replicating the first virtual container to create a plurality of replicated virtual containers, each of the plurality of replicated virtual containers a duplicate of the first virtual container, and the plurality of replicated virtual containers configured to run synchronously; generating a randomized hopping set that defines a set of replicated virtual containers from the plurality of replicated virtual containers, the randomized hopping set establishing a sequence of the set of replicated virtual containers in which to run the one or more software processes; and running the one or more software processes across the set of replicated virtual containers based on the sequence of the randomized hopping set.
