Abstract: Changes are made to a virtual network for an endpoint based on the authenticated user identity of the endpoint. The system includes a server and a controller associated with a network fabric to which the endpoint is connected. The network fabric includes network elements to carry network traffic for the endpoint.

The controller receives a notification from the server that the network traffic for the endpoint associated with the network address is to be routed over the first virtual network. The controller updates routing information to associate the network address with the first virtual network and sends the updated routing information to the network elements of the network fabric.

Abstract: Various systems and methods for performing bit indexed explicit replication (BIER). For example, one method involves receiving a membership request at a node. The membership request is received from a host and the membership request identifies a multicast group. In response to receiving the membership request, the node generates a membership message. The membership message includes information identifying the multicast group and information identifying the node. The node transmits the membership to an overlay participant that stores a bit string associated with the multicast group.

Abstract: The embodiments herein uses sensor APs (e.g., APs that do not associate with client devices) to detect changes in physical topology that affect cell coverage areas and determine cell edges for different client devices. In one embodiment, using test signals (e.g., test probes) transmitted by the sensor APs which are received at normal APs which do associate with client devices, a controller can generate baselines which characterize the signals received from the sensor APs at the normal APs. At intervals or in response to an unexpected action by a client device, one or more of the sensor APs can transmit another test signal. Because the test signal can be received at multiple normal APs, the controller can compare the test signal to the baselines to identify whether there has been a change in physical topology that affects the cell coverage area for the client device.

Abstract: In one embodiment, a network agent, associated with an operating system of a computing device, tracks socket connection calls made by a plurality of cotenant processes on the computing device that share a common network transport between the computing device and a remote computing device. The network agent may then extract a process identification (ID) for the socket connection calls, the process ID identifying which particular cotenant process of the plurality of cotenant processes is making each particular socket connection call. While monitoring network metrics of network traffic flows over socket connections between the computing device and the remote computing device, the network agent may attribute given network metrics from particular socket connections to a corresponding cotenant process based on the correlated process ID for the socket connection. As such, the network agent may then report the network metrics as attributed to the corresponding cotenant processes.

Abstract: An extended service-function chain (SFC) proxy is hosted on a network node and connected to a service path formed by one or more network nodes hosting a chain of service-functions applied to packets traversing the service path. The packets each include a service header having a service path identifier and a service index. A packet of a traffic flow destined for a service-function is received from the service path and sent to the service-function. An indication to offload the traffic flow is received from the service-function. The indication is stored in a flow table having entries each identifying a respective traffic flow. A subsequent packet of the traffic flow is received from the service path. The flow table is searched for the indication to offload the traffic flow. Upon finding the indication, the service-function is bypassed, and the subsequent packet is forwarded along the service path.

In some implementations, the second set of source packets satisfies a second encoding pattern that is different from the first encoding pattern. In some implementations, the first and second encoding patterns characterize an encoding structure determined as a function of a channel characterization vector.

Abstract: Analog echo cancellation with Digital-to-Analog Converter (DAC) noise suppression may be provided. First, a test signal may be sent through an echo cancelation pathway during a downstream silence period and an upstream silence period. The echo cancelation pathway may comprise an electronic element. Next, a loopback response signal may be received in response to sending the test signal through the echo cancelation pathway. Then a channel response model may be created that characterizes a channel response of the loopback response signal and a non-linear model may be created that characterizes a non-linearity of the electronic element. Next, for a downstream signal, a non-linear component may be generated based on the created non-linear model. The generated non-linear component may be convolved with the created channel response model. The convolved non-linear component may then be subtracted from an upstream signal.
