Abstract: A method for establishing a call over a packet network may include receiving a call request on a packet network from an originating call device. Status one or more segments of a transmission path may be determined. If the status of the segments are within a first range, the call between the originating and terminating call device over the determined transmission path at a first data rate may be established. Otherwise, if the status of one or more segments is within a second range, a determination as to whether the originating trunk and terminating segment can operate at a second data rate may be made, and, if so, the call may be established over the transmission path between the originating call device and terminating call device at the second data rate.

Abstract: The disclosed embodiments include a system, computer program product, and method for routing a call over a packet network. A call request may be received from a calling party to call a called party at a network address. At least one potential call path over a packet network may be determined to connect the calling party to the called party at the network address. Network performance information associated with each potential call path may be accessed and a determination may be made that each of the call paths are impaired or congested. In response to determining that each of the call paths are impaired or congested, the call may be routed over a call path other than one of the at least one potential call paths to enable the calling party to communicate with the called party.

Abstract: A system and method for separating clock recovery for a pseudowire communication. An incoming signal is received for a pseudowire communication. The incoming signal is separated into a first signal and a second signal. Packets within the first signal are ordered in a first register. A clock signal is extracted from the second signal in a second register to generate a modified clock signal. A delay is incurred during generating of the modified clock signal. The first signal is communicated utilizing the modified clock signal.

Abstract: A method for establishing a call over a packet network may include receiving a call request via an originating trunk on a packet network from an originating call device. Status of an originating trunk and terminating segment may be determined. If the status of the originating trunk and terminating segment are within a first range, the call between the originating and terminating call device over the determined transmission path at a first data rate may be established. Otherwise, if the status of the originating trunk or terminating segment is within a second range, a determination as to whether the originating trunk and terminating segment can operate at a lower data rate may be made, and, if so, the call may be established over the transmission path between the originating call device and terminating call device at the lower data rate.

Abstract: When the physical network is transitioned into a virtual network, functionality provided by physical ports are no longer available in the virtual machine (“VM”) environments. Physical to virtual network transport function abstraction may be implemented to provide software applications running in the VM with state information or similar information necessary for the software applications to continue running, without the physical ports that would provide such information in a physical system. In some embodiments, a virtual machine manager might send first information to a virtual infrastructure manager, which might send second information to a virtualized application manager or orchestrator. The virtualized application manager or orchestrator might in turn send third information to a virtualized application running in a virtual machine or container. The first, second, and/or third information might include state information (e.g., state change information) that enable software applications running in the VM to continue running, without physical ports.

Abstract: Novel tools and techniques are provided for implementing a virtualization congestion control framework. In one aspect, a method might include a hypervisor assigning application resources of a virtual machine (“VM”), which operates on a host computing system, with maximum allowable settings to each software application to be executed on the VM. The hypervisor or an orchestrator might determine a running mode of the host computing system, and might execute the software application(s) using running mode attributes of the determined running mode. The hypervisor or the orchestrator might monitor application resource utilization, and, based on a determination that application resource utilization has changed, might modify allocation of application resources to each of the software application(s). In some cases, the hypervisor or the orchestrator might monitor for mass congestion indicators, and, based on a determination that a mass congestion indicator is present, might modify the running mode of the host computing system.
