摘要： A unified access control component (UACC) can maintain information relating to network access information and physical location information associated with respective users who may access a network that can include network resources (e.g., applications, information). The UACC can cross reference the network access information (e.g., user network access events, credentials, and policy) and physical location information (e.g., user physical access events, credentials, and policy) and can generate and enforce a unified network access policy based on network access information and physical location information associated with a particular user. After network access privileges have been granted to a user, the UACC can continue to monitor the user. The UACC can include a dynamic authentication component that can request a user re-authenticate if a change in the physical location and/or network access associated with the user is detected, such that a re-computation of network access privileges is desired.
摘要翻译：统一的访问控制组件（UACC）可以维护与可能访问可以包括网络资源（例如，应用，信息）的网络的相应用户相关联的网络访问信息和物理位置信息的信息。 UACC可以交叉参考网络访问信息（例如，用户网络访问事件，凭据和策略）和物理位置信息（例如，用户物理访问事件，凭据和策略），并且可以生成并实施基于统一的网络访问策略关于与特定用户相关联的网络访问信息和物理位置信息。在向用户授予网络访问权限之后，UACC可以继续监视用户。如果检测到与用户相关联的物理位置和/或网络访问的改变，则UACC可以包括动态认证组件，其可以请求用户重新认证，使得期望重新计算网络访问特权。

摘要： In one embodiment, a system includes a video mixer coupled with an audio mixer for exchange of information that includes a first set of delay values respecting input audio streams received by the audio mixer from a plurality of source endpoints, and output audio streams sent from the audio mixer to a plurality of destination endpoints. The information further including a second set of delay values respecting the corresponding input video streams. The audio mixer calculates end-to-end video delays, and the video mixer calculates end-to-end audio delays. The audio mixer delays the output audio streams to equalize the end-to-end audio and video delays in the event that the end-to-end audio delays are less than the end-to-end video delays, and the video mixer delays the output video streams to equalize the end-to-end audio and video delays in the event that the end-to-end video delays are less than the end-to-end audio delays.

摘要： In one embodiment, a method includes dropping an initial series of video frames received by a video conferencing system from a first endpoint that has entered a video conference session as a first participant. One or more fast video update (FVU) messages received by the video conferencing system from the first endpoint during an enabling time period are then discarded. A single FVU message is then to the first endpoint after the video conferencing system has become enabled with respect to the first endpoint. An I-frame received from the first endpoint in response to the single FVU message is then sent back to the first endpoint. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

摘要： A node for routing of calls in a network has an interface coupled to the network and at least one processor operable to route a packet-based call to a telephony destination in accordance with a protocol that includes a set of attributes that describe packet-network routing characteristics of one or more Internet Protocol (IP)-IP gateway devices in the network. The attributes are used by the at least one processor to specify a call route through an IP-IP gateway device for the packet-based call. The set of attributes include a first attribute that identifies a total administratively provisioned bandwidth capacity available on a given call route to accommodate application traffic, and a second attribute that identifies a current bandwidth that is available on the given call route to accommodate the application traffic at a given point in time. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： A Real-Time Protocol (RTP) source node of a network operates to send a first data packet of a first size to a destination node over a path of the network that includes a plurality of intermediate nodes, at least one of the intermediate nodes having a maximum transmission unit (MTU) size smaller than the first size such that fragmentation of the first data packet occurs. The destination node sends back to the source node a RTCP report that includes a number of fragments received and a largest minimum data packet size. In response, the source node sends subsequent data packets having a second size less than or equal to the largest data packet size of the fragments. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
