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.

摘要： An intelligent switch and method are described herein which help to effectively retransmit a lost packet that is associated with a television broadcast stream to one or more set-top box(es) (STBs). In one embodiment, the intelligent switch functions as follows: (a) receives, from one of the STBs, a request for a retransmission of a lost packet; (b) forwards, to a broadcast television (BTV) server, the request for the retransmission of the lost packet; (c) initiates a suppression period during which if subsequent request(s) for the retransmission of the same lost packet are received from other STB(s) then the subsequent request(s) would not be forwarded to the BTV server; (d) receives, from the BTV server, a retransmitted lost packet which is associated with the request for the retransmission of the lost packet; and (e) sends the retransmitted lost packet to the STB which sent the request for the retransmission of the lost packet and to the other STB(s) which sent the subsequent request(s) for the retransmission of the lost packet.

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： Fully redundant clock systems are provided on network nodes coupled by redundant multisegment psuedowires (MSPWs) within an internet-protocol (IP)-based mobile backhaul network. The primary clock system includes a primary master clock on a first node and a primary slave clock on a second node coupled via a primary MSPW, while the secondary clock system includes a secondary master clock on the first node and a secondary slave clock on the second node coupled via a secondary MSPW. The primary and secondary slave clocks synchronize with their respective primary and secondary master clocks via their respective MSPWs. A clock controller maintains the secondary clock system in a hot-stand-by mode, and upon determining that a switch-over is needed, automatically switches from the primary clock system to the secondary clock system.

摘要： An idle mode load balancing capability enables balancing of idle mode wireless devices across wireless carriers in order to ensure that the possibility of congestion on any given wireless carrier is reduced or even minimized when idle mode wireless devices become active. The idle mode load balancing may be performed for wireless carriers by determining relative numbers of idle mode wireless devices on the wireless carriers and performing idle mode load balancing for the wireless carriers based on the relative numbers of idle mode wireless devices on the wireless carriers. The relative number of idle mode wireless devices on a wireless carrier may be determined based on a change in load on the wireless carrier during the observation period, which may be determined based on an observed change in load on the wireless carrier and a load correction associated with session terminations on the wireless carrier.

摘要： Systems and methods are provided for adjusting Radio Resource Control (RRC) timers in a Radio Access Network (RAN). The system manages radio communications between a mobile device and a base station, and further transitions the mobile device between Radio Resource Control (RRC) states based upon application-layer data traffic for the mobile device and a timer value. Additionally, the system determines an overhead load based on network-layer signaling events associated with at least one RRC transition for the mobile device, and determines a bearer load based on the application-layer data traffic for the mobile device. Based upon the overhead load and the bearer load, the system adjusts the timer value.

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.
