摘要： A live streaming system/method provides cross platform live streaming capabilities to mobile devices. The live streaming system includes a live streaming recorder operative to (1) capture a live media stream generated by a live media source and save the captured live media stream as a recorded stream in a recorded media file, and (2) transcode the recorded stream into a plurality of transcoded media files of respective different media encoding formats. The system further includes a stream distribution subsystem operative to generate a plurality of distributed media streams each generated from one or more of the transcoded media files, each distributed media stream being delivered to a corresponding set of the mobile endpoint devices.

摘要： A live streaming system/method provides cross platform live streaming capabilities to mobile devices. A file format compatible with legacy HTTP infrastructure is used to deliver media over a persistent connection. Legacy client media players can dynamically change the encoded rate of the media delivered over a persistent connection. Standard HTTP servers may be used without modification, leveraging standard media players embedded in mobile devices for seamless media delivery over wireless networks with high bandwidth fluctuations.

摘要： A method for estimating end-to-end quality of service (QOS), such as packet loss, delay, and delay jitter, in a packet-switched communications network includes steps for calculating packet loss and packet delay each router output link in a network path and using the packet loss and packet delay calculations for each individual router output link to estimate end-to-end QOS. The method includes calculating the loss probability for all possible numbers of active sources to take into account changes in the number of active sources as active sources connect to and disconnect from the network. As a result, the inventive method allows the number of active sources to vary in its estimation of end-to-end packet loss, delay, and delay jitter for enhanced Internet Protocol network planning.

摘要： A policy server operates to configure differentiated services over multi-protocol label switching (Diffserv/MPLS) in a communications network. The policy server enables the definition and deployment of a customer policy, a network policy and a mapping policy. The policy server is arranged to create a group of MPLS tunnels, and associate the tunnels to the mapping policy and the customer policy. The customer policy includes a tunnel group identifier and a tunneling mode, and maps customer traffic to MPLS tunnels. The policy server translates the customer policy, the network policy and the mapping policy into device-specific commands, and then deploys the device-specific commands to the network interfaces of the affected network devices.

摘要： Mechanisms for QoS mapping rules on a mobile network between a UMTS layer and an IP layer are provided. A policy server is coupled to the SGSNs and GGSNs on the mobile network and maintains a centralized location for layer QoS mapping on the mobile network. Three mapping mechanisms have been provided, including an out-sourcing mechanism, a provisioning mechanism, and a hybrid mechanism. The out-sourcing mechanism uses the policy server to handle PDP context events and supply the appropriate rules to the appropriate support node. Under the provisioning mechanism, the policy server pushes down the corresponding mapping rules to each support node across the network in advance of any PDP context event. The hybrid mechanism utilizes a combination of the out-sourcing mechanism and the provisioning mechanism. The mechanisms ensure consistent UMTS layer QoS to IP layer QoS mapping across a mobile network.

摘要： An electrical switch has a housing having an opening, fixed contacts located in the housing, a switching member supported in the housing for movement, and at least one moving contact movable by the switching member for movement to come into contact with and out of contact from the fixed contacts. An actuator is disposed in the opening for movement to actuate the switching member and in turn the moving contact. A gap is formed between the actuator and the opening that surrounds the actuator. A rubber deformable seal is connected across the opening and the actuator to seal off the gap, thereby avoiding entrance of foreign matter through the gap into the housing.
