摘要： A method and apparatus are disclosed that seek to improve the quality of service that is experienced during the transmission of a stream of packets across one or more paths. In particular, a transmitting node encodes a source stream of data (e.g., audio, video, etc.) into one or more sub-streams, and distributes those sub-streams onto multiple network transmission paths. In accordance with the illustrative embodiment of the present invention, the transmitting node evaluates the quality of service of a first network path that fails to provide a quality-of-service guarantee. When the quality of service of the first network path becomes unsatisfactory, the coding of one or more sub-streams that are being transmitted on a second network path is adjusted. In other words, the coding on a second channel is adjusted in response to the changing conditions on a first channel.

摘要： A technique is disclosed that evaluates a network path between (i) a first node in a first subnetwork of endpoint nodes, such as IP phones, and (ii) a second node in a second subnetwork. A “ricochet” node in the network path evaluates the path by probing one or both subnetworks, where the ricochet node acts as relay for traffic packets being transmitted between the two subnetworks. A given relay has only to probe a single, representative node within a subnetwork at any given time in order to obtain performance data that is representative of the subnetwork overall. By probing the representative node, the relay is able to acquire an assessment of network conditions that is valid for the path between the relay and any endpoint in the subnetwork. As a result, the disclosed technique reduces the probing overhead when many endpoint nodes on a given subnetwork are simultaneously active and experiencing adverse network conditions.
摘要翻译： 公开了一种技术，其评估（i）端点节点的第一子网络中的第一节点（例如IP电话）和（ii）第二子网络中的第二节点之间的网络路径。 网络路径中的“弹射”节点通过探测一个或两个子网络来评估路径，其中弹性节点用作在两个子网络之间传输的业务分组的中继。 给定的中继只能在任何给定的时间探测子网内的单个代表性节点，以获得代表子网的性能数据。 通过探测代表节点，中继器能够获取对于继电器和子网中的任何端点之间的路径有效的网络条件的评估。 因此，所公开的技术减少了给定子网上的许多端点节点同时处于活动状态并且经历不利的网络条件时的探测开销。

摘要： A method for providing priority access to 802.11 endpoints. The method includes the steps of sending a Clear To Send (CTS) frame from a designated station, without requiring a Request to Send (RTS) frame from a first station. The CTS frame includes a field identifying the first station for commencing transmission, and a field indicating a duration of transmission. A deferring step is also performed for deferring any transmissions of stations other than the first station until after the duration indicated in the CTS frame has passed.

摘要： A method and an apparatus are disclosed that provide a privilege-granting technique for enabling a service-providing domain to grant a privilege to a requesting user in a service-requesting domain. A request handler in the service-providing domain, which comprises one or more service-associated resources, receives a user request to use a service and requests a token from a privilege-granting server, in accordance with the illustrative embodiment of the present invention. Upon receiving the token that specifies a granted privilege from the privilege-granting server, the request handler extends the privilege to the requesting user. Alternatively, the request handler can request a plurality of tokens in advance from the privilege-granting server; after receiving the tokens, the request handler extends a privilege to each requesting user as the handler receives requests to use one or more services.
