摘要： Generating a binding between a source address and one or more roles of a user (102) accessing the network (108) and distributing the binding to a filter node (140). The source address is currently assigned to the device (104). The binding may be generated by one or more nodes on an ingress path used during authentication of the user (102). The binding may be distributed to the filter node (140) on demand or without any request from the filter node (140). Responsive to a determination that the user (102) is associated with a new source address, a new binding is generated to associate a now source address with the one or more roles for the user. The new binding distributed to the filter node (140). Another aspect is a method of enforcing a role based security policy at a filter node (140), using bindings of source addresses to roles.
摘要翻译：生成源地址与访问网络（108）的用户（102）的一个或多个角色之间的绑定，并将绑定分发到过滤器节点（140）。源地址当前被分配给设备（104）。绑定可以由在用户（102）的认证期间使用的入口路径上的一个或多个节点生成。可以根据需要或不经过来自过滤器节点（140）的任何请求将绑定分发到过滤器节点（140）。响应于用户（102）与新的源地址相关联的确定，生成新的绑定以将现在的源地址与用户的一个或多个角色相关联。分配给过滤器节点（140）的新绑定。另一方面是使用源地址到角色的绑定来在过滤器节点（140）上实施基于角色的安全策略的方法。

摘要： The Real-time Transport Protocol (RTP) and its related standards define a retransmission packet format and a way to give feedback via Negative ACKnowledge (NACK) packets for data that has been lost. In one embodiment, a unicast RTP repair session is associated with a main Source Specific Multicast (SSM) multicast session. Real-time Transport Control Protocol (RTCP) NACK packets are then used for feedback to a SSM feedback target address. This dynamically instantiates unicast RTP repair for multicast sessions. The repair scheme can be used for repairing multicast channels or joining new multicast channels. In another embodiment, a media transmission device shares an IP address with one or more other media transmission devices. The shared IP address can also be used to route multiple identical multicast media streams to different media stream receivers.
摘要翻译：实时传输协议（RTP）及其相关标准定义了重传分组格式，并且通过负数确认（NACK）分组为丢失数据提供反馈的方法。在一个实施例中，单播RTP修复会话与主要源特定多播（SSM）多播会话相关联。然后，实时传输控制协议（RTCP）NACK分组用于反馈到SSM反馈目标地址。这可以动态实例化多播会话的单播RTP修复。修复方案可用于修复组播信道或加入新的组播信道。在另一个实施例中，媒体传输设备与一个或多个其他媒体传输设备共享IP地址。共享IP地址也可以用于将多个相同的多播媒体流路由到不同的媒体流接收器。

摘要： In one embodiment, a hybrid packet repair scheme (12) adaptively switches among unicast retransmission (32), multicast retransmission (34), and Forward Error Correction (36) depending on the receiver population and the nature of the error prom pting the repair operat ion. The NACK patterns (26) are used to heuristically determine the degree of correlation among packet losses. In an additional embodiment, wasting bandwidth and processing on retransmissions of FEC (36) that will fail to correct the errors is avoided by evaluating the nature of the error and the bandwidth needed to optimally repair it. Unicast retransmission (32), multicast retransmission (34), or FEC repair is then dynamically performed according to the loss patterns derived from the NACK arrivals and other network conditions.
摘要翻译：在一个实施例中，混合分组修复方案（12）根据接收机群体和修复操作的错误的性质自适应地在单播重传（32），多播重传（34）和前向纠错（36）之间切换离子。 NACK模式（26）用于启发式地确定分组丢失之间的相关程度。在另外的实施例中，通过评估错误的性质和最佳地对其进行修复所需的带宽来避免浪费带宽以及不能纠正错误的FEC（36）重发的处理。然后根据从NACK到达和其他网络条件导出的丢失模式动态地执行单播重传（32），组播重传（34）或FEC修复。

摘要： In one embodiment, a router receives a real-time multimedia flow that comprises IP packets. The router then processes values included in the Identifier fields of the IP packets using resources similar to those used in the monitoring of RTP flows to identify metrics for the real-time multimedia flow. The metrics may be transferred to a remote management device for aggregation with metrics output by other routers located on the data path for the real-time multimedia flow.

摘要： In one embodiment, a buffering server transfers a dynamic burst transfer of data encoded using an inter-coded compression technique. The dynamic burst transfer is timed so that an initial transfer rate is reduced to a remaining transfer rate at the same time or before a decoding endpoint joins a corresponding data stream. The decoding endpoint merges the video stream and the dynamic burst transfer to decode and quickly reconstruct a displayable video frame.
摘要翻译：在一个实施例中，缓冲服务器传送使用帧间编码压缩技术编码的数据的动态突发传送。动态突发传输被定时，使得初始传输速率在同一时间或在解码端点加入相应的数据流之前降低到剩余的传输速率。解码端点将视频流和动态突发传输合并以解码并快速重构可显示的视频帧。

摘要： In one embodiment, an endpoint sends messages containing Simple Traversal of User Datagram Protocol (UDP) Through Network Address Translators (NATs) (STUN) requests to traceroute a path to the remote endpoint. The traceroute may be completed through security devices such as NATs and firewalls. Receipt of a STUN response from the remote endpoint signals that one of the traceroute packets reached the remote endpoint whereas the other traceroute packets have elicited error responses from intermediary, on-path routers, allowing these routers to be identified.
摘要翻译：在一个实施例中，端点通过网络地址转换器（NAT）（STUN）请求发送包含用户数据报协议（UDP）的简单遍历的消息，以跟踪到远程端点的路径。可以通过NAT和防火墙等安全设备来完成跟踪路由。来自远程端点的STUN响应的接收指示一个跟踪路由分组到达远程端点，而另一个跟踪路由分组已经从中间路由路由器引出错误响应，允许标识这些路由器。
