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. 37 CFR 1.72(b).
摘要翻译：用于在网络中路由呼叫的节点具有耦合到网络的接口和至少一个处理器，其可操作以根据包括描述分组网路由的一组属性的协议将基于分组的呼叫路由到电话目的地网络中一个或多个互联网协议（IP）-IP网关设备的特征。这些属性被至少一个处理器用于通过用于基于分组的呼叫的IP-IP网关设备指定呼叫路由。所述属性集合包括第一属性，其识别在给定呼叫路由上可用于适应应用流量的总管理配置的带宽容量;以及第二属性，其识别在给定呼叫路由上可用于适应应用流量的当前带宽一个给定的时间点。要强调的是，该摘要被提供以符合要求抽象的规则，允许搜索者或其他读者快速确定技术公开内容的主题。提交它的理解是，它不会用于解释或限制权利要求的范围或含义。 37 CFR 1.72（b）。

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-epd 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-epd audio and video delays in the event that the end-to-end video delays are less than the end-to-end audio delays.
摘要翻译：在一个实施例中，系统包括与音频混合器耦合的视频混合器，用于交换信息，所述信息包括与多个源端点相关的音频混合器接收的输入音频流的第一组延迟值，以及输出从音频混合器到多个目的地端点。所述信息还包括相对于相应的输入视频流的第二组延迟值。音频混合器计算端到端视频延迟，视频混合器可以计算端到端音频延迟。在终端到epd音频延迟小于端到端视频延迟的情况下，音频混合器延迟输出音频流以均衡端到端音频和视频延迟，并且视频混合器延迟输出视频流以在终端到终端视频延迟小于端对端音频延迟的情况下均衡终端到epd音频和视频延迟。

摘要： A conferencing system (10) includes a mixer (12) operable to process audio and video packets received from a plurality of endpoint devices (15, 16, 17, 19, 21 ), and to transmit a processed audio / video stream back to the endpoint devices (15, 16, 17, 19, 21). The endpoint devices (15, 16, 17, 19, 21) may be configured with an associated video camera (18, 20, 22). A server (11) connects with the mixer (12) and the endpoint devices (15, 16, 17, 19, 21). The server (11) is operable to send a first transmission to a first endpoint device (17) that causes the first endpoint device (17) to stop transmitting video packets to the mixer (12). The server (11) is further operable to send a second transmission to a second endpoint device (21 ) that causes the second endpoint device (21) to start transmitting video packets to the mixer.
摘要翻译：会议系统（10）包括可操作以处理从多个端点设备（15,16,17,19,21）接收的音频和视频分组的混合器（12），并且将经处理的音频/视频流发送回端点设备（15,16,17,19,21）。端点设备（15,16,17,19,21）可以配置有相关联的摄像机（18,20,22）。服务器（11）与混合器（12）和端点设备（15,16,17,19,21）连接。服务器（11）可操作以向第一端点设备（17）发送第一传输，其使得第一端点设备（17）停止向混频器（12）发送视频分组。服务器（11）还可操作以向第二端点设备（21）发送第二传输，使得第二端点设备（21）开始向混合器发送视频分组。
