Abstract: Hierarchical congestion identification and control hardware supports multi-level congestion control at flow, tenant and virtual machine (VM) levels. Hardware implementation expedites response to congestion notifications and frees-up processor bandwidth. A hierarchy of transmit shapers in a transmit ring scheduler isolate rate adjustments for flows, tenants and VMs. The hierarchy of shapers provide a hierarchy of congestion control nodes to control flows and aggregate flows. Hardware quickly associates congested flows with shapers before or after receiving a congestion notification. The associations may be used by any flow control algorithm to selectively rate-control shapers to control flow rates. Shaper associations and configured states, scheduler configuration, congestion states, thresholds and other flow information may be stored and monitored to filter data flows that need attention and to raise alerts at flow, tenant and VM levels.

Abstract: Embodiments enable a network operator to use any (and a single) network management system (NMS) that it desires to manage a network having mixed fiber to the home optical network units (ONUs) and coaxial connected cable modems. For example, embodiments enable a cable company operator to use a DOCSIS (Data Over Cable Service Interface Specification) NMS (which the cable company already uses to manage its DOCSIS network) to manage such mixed network, by a simple addition of a DOCSIS Mediation Layer (DML) module between the NMS and the optical line terminal (OLT). On the other hand, embodiments enable a telephone company operator to use a standard EPON (Ethernet Passive Optical Network) OLT NMS with minor OLT and OAM (Operations, Administration, and Maintenance) protocol modifications to manage the same mixed network.

Abstract: A wireless communication device (WDEV) receives, detects, snoops, etc. (generally, “receives”) signals that are transmitted between two other WDEVs and extracts information therefrom to determine the location of the WDEV. These signals can include fine timing measurement (FTM) and/or timestamps related information as part of a frame exchange procedure between those two other WDEVs. A new protocol specifies when such an FTM and/or timestamps frame exchange procedure is performed between the two other WDEVs, and the WDEV intelligently detects/receives such signals at such specified times. When the WDEV operates in a reduced power or sleep state, the WDEV awakens from the reduced power or sleep state at the appropriate times to detect FTM and/or timestamps related information of such a frame exchange procedure. The WDEV then can process such FTM and/or timestamps related information for use in determining the location of the WDEV relative to the two other WDEVs.
