摘要： A service controller for a cell switched network services a plurality of connection queues within the network according to a fair rate which may be weighted for each of the connection queues. Connection queues may be serviced by moving cells from one or more of the connection queues to a class of service queue and the fair rate may be computed according to the length of the class of service queue and cell arrival and departure rates to and from the class of service queue. For example, the fair rate may be computed by computing a target rate for servicing the connection queues, computing an observed arrival rate for cells arriving at the class of service queue, and computing the fair rate according to a ratio of the target rate to the observed arrival rate. The target rate may be approximated according to an amount of available bandwidth for the class of service queue and the number of cells serviced from the class of service queue in a period of time. Further, the fair rate may be periodically recomputed and doubled at each periodic recomputation. The fair rate computed for servicing cells may also be used for explicit rate control within the network.
摘要翻译：用于小区交换网络的服务控制器根据可以为每个连接队列加权的公平速率来服务网络内的多个连接队列。可以通过将小区从一个或多个连接队列移动到一类服务队列来服务连接队列，并且可以根据服务等级队列的长度和到班级的小区到达和离开速率来计算公平速率的服务队列。例如，可以通过计算用于服务连接队列的目标速率，计算到达服务队列等级的小区的观察到的到达速率来计算公平率，并且根据目标速率与观察到达率。目标速率可以根据服务队列类别的可用带宽的数量和在一段时间内从服务队列服务的小区的数量近似。此外，在每次周期性重新计算时，可以周期性地重新计算公平比率并加倍。为服务小区计算的公平率也可用于网络内的显式速率控制。

摘要： A method and apparatus are described for determining an equivalent capacity of a transport device in a network switch for a traffic data stream. A data collector collects at least one traffic parameter for the traffic data stream arriving at a queue of the transport device for a specified quality of service (QoS) class. A bandwidth estimator is coupled to the data collector to estimate an effective bandwidth using the at least one traffic parameter. The estimated effective bandwidth corresponds to the equivalent capacity of the transport device.

摘要： During a video conference between a local endpoint and a remote endpoint, a display at the local endpoint may be configured to provide perspective-dependent views to local video conference participants. A local endpoint may receive a plurality of video streams and identify a first video stream that provides a first view of a remote participant and a second video stream that provides a second view of that participant taken concurrently from a different angle. A display at the local endpoint may display the first video stream at a first viewing angle that only allows the first view of the remote participant to be seen from a first region. The display may also concurrently display the second video stream at a second viewing angle that only allows the second view of the remote participant to be seen from a second region different than the first region.
