摘要： A network management system and a method are described herein that determine if one or more devices (e.g., consumer premises equipment(s)) are experiencing an unacceptable packet loss for downstream multicast traffic in an access network. In one embodiment, the network management system performs the following operations: (1) cause a trigger probe to be sent to the one or more devices, where each trigger probe contains information which causes the corresponding device to start a packet loss measurement; and (2) receive an unacceptable loss measurement message from one of the devices if that one device experienced packet losses over a certain period of time that exceeded a predetermined threshold which would be an indication that the one end device is experiencing an unacceptable packet loss.

摘要： An access node (e.g., Digital Subscriber Line Access Multiplexer) and a method are described herein that proactively monitor the connectivity of one or more end devices (e.g., residential gateways). In one embodiment, the access node performs the following: (a) receives continuity check messages from at least one of the end devices; (b) polls the received continuity check messages to ascertain the connectivity of each end device; and (c) if at least one continuity check message is detected as missing from one of the end devices during the polling step, then an alarm message is sent indicating a loss of connectivity to the one end device. Thereafter, an edge router (e.g., Broadband Network Gateway) would receive the alarm message and know there is no longer a connection to the one end device.

摘要： A method for creating an Operation Administration and Maintenance frame in an Ethemet/Transport Multi-Protocol Label Switch hybrid network. The method includes mapping values in an Ethernet Operation Administration and Maintenance data field in a protocol data unit (PDU) in a first Ethernet Operation Administration and Maintenance frame (Ethernet OAM frame) into a Transport Multi-Protocol Label Switch Operation Administration and Maintenance data field in PDU in a first Transport Multi-Protocol Label Switch Operation Administration and Maintenance frame (TMPLS OAM frame) and mapping values in first control parameter fields in the first Ethernet OAM frame into second control parameter fields in the first TMPLS OAM frame. The PDU in the first TMPLS OAM frame includes added extra fields as necessary, and the second control parameter fields further comprise preselected default information and routing information mapped from values stored in a memory.

摘要： Techniques for estimating and improving a Quality of Experience (QoE) associated with a video stream played on user equipment are provided. The video stream may be an HTTP adaptive streaming (HAS) video flow, and a network element is configured to recognize certain aspects of the video flow and modify the delivery rate to improve the QoE without need additional information from either the user equipment (UE) or content provider. The network element may be configured to monitor the buffer at the UE to prevent underfill, configured to monitor multiple changes in delivery rate requests to prevent abrupt video presentation, and configured to recognize the initiation of a HAS video flow and increase buffer fill to reduce start-up time delay.

摘要： A diagnostic tool is provided for calculating the availability of multi-segment pseudowires within an internet protocol (IP)-based mobile backhaul network. A control message is transmitted from an originating node towards a destination node within the IP-based mobile backhaul network over a primary multi-segment pseudowire and a secondary multi-segment pseudowire. From the response messages received from intermediate nodes positioned between the network node and the destination node along the primary multi-segment pseudowire and the secondary multi-segment psuedowire, the originating node determines the identities of each of the intermediate nodes, and calculates a respective individual availability of the primary multi-segment pseudowire and the secondary multi-segment pseudowire.
