Abstract: This disclosure describes techniques for performing a remote front-drop of data for recovery after a pipeline stall. The techniques include using a receiver-side dropping strategy that is driven from the sender-side. Components of a pipeline determine whether a pipeline is operating within specified latency constraints (e.g., experiencing a pipeline stall). Upon detecting a pipeline stall, the sending device is notified of the stall. Once the sending device is notified of the pipeline stall, the sending device can determine what action(s) to perform to address the pipeline stall. For example, the sending device may instruct one or more components of the pipeline to discard already sent data that has not been processed. This allows the older data to be dropped on the stalled pipeline while keeping the more recently sent data.

Abstract: A system and method are provided for allocating bandwidth and metering data flows within a wireless mesh-tree network. The network includes a wireless LAN controller (WLC), a root access point (RAP), and mesh access points (MAPs), which are arranged in respective hop levels corresponding to the number of links a given MAP is removed from the RAP. The WLC allocates available data rates (ADRs) to the respective MAPs, and each MAP then apportions its ADR among various origination types of data flowing through the given MAP (e.g., backhaul, ethernet-bridged, and client data types). The MAPs can use a token bucket filter (TBF)-like mechanism to enforce this apportionment. WiFi multi-media (WMM) based access classes can be used to shape the data flows (e.g., an NC access class assigned to topology maintenance traffic ensures it is fed directly into a WMM queue).

Abstract: A first access point of a wireless network minimizes Media Access Control (MAC) address collisions in the wireless network. The first access point receives an association request from a first wireless device. The association request identifies a first MAC address of the first wireless device. The first access point determines whether a second wireless device is associated with the wireless network using the first MAC address. Responsive to a determination that the second wireless device is associated with a second access point of the wireless network, the first access point obtains a virtual MAC address for the first wireless device. The first access point translates between the first MAC address and the virtual MAC address for network traffic of the first wireless device.

Abstract: Radio discovery for a mesh Access Point (AP) may be provided. Topology information associated with a first network may be received wherein the first network may comprise a mesh network. A Topology Descriptor Message (TDM) may then be created based on the topology information. The TDM may then be transmitted by a first Access Point (AP).

Abstract: The present technology pertains to identifying one or more sub-components of one or more network devices in a network environment; disaggregating the one or more sub-components from corresponding network devices of the one or more network devices; monitoring one or more functional flows across the one or more sub-components on a sub-component basis to generate functional flow data associated with the one or more sub-components; and generating analytics of the network environment on a sub-component basis from the functional flow data.
