Abstract: A peer-to-peer forwarding node supports the operation of a teleconference across a telecommunications network. The telecommunications network comprises a plurality of nodes including one or more source locations and one or more remote locations. The teleconference includes teleconference participants at each of the source and remote locations. The peer-to-peer forwarding node is located at a given one of the plurality of nodes. The peer-to-peer forwarding node comprises a receiver and a transmitter. The receiver receives a request from a telecommunications controller to provide peer-to-peer forwarding of a media signal to be received from a first one of the source locations to a first one of the remote locations and which further receives the media signal from the first one of said source locations. The transmitter forwards the media signal from the first one of the source locations to the first one of the remote locations.

Abstract: A user accesses the Internet through a hybrid data communications system architecture in which upstream service is provided via the local loop of the public switched telephone network (PSTN) and downstream service is provided via a cable television (CATV) network. The Cable Modem Data Termination system (CMTS) includes a routing table. Upon detection of a CATV service interruption, the CMTS re-routes IP traffic destined for a destination IP address (IP1) associated with the user to a different IP address, or endpoint, as a function of the routing table. In this instance, the different IP address is associated with equipment that provides downstream IP service to the user via the local loop of the PSTN.

Abstract translation: 用户通过经由公共交换电话网（PSTN）的本地环路提供上游服务的混合数据通信系统架构来访问因特网，并且经由有线电视（CATV）网络提供下游服务。 有线调制解调器数据终端系统（CMTS）包括路由表。 在检测到CATV服务中断时，CMTS将去往与用户相关联的目的地IP地址（IP1）的IP流量路由到作为路由表的函数的不同IP地址或端点。 在这种情况下，不同的IP地址与通过PSTN的本地环路向用户提供下行IP服务的设备相关联。

Abstract: The invention provides improved computer network firewalls which include one or more features for increased processing efficiency. A firewall in accordance with the invention can support multiple security policies, multiple users or both, by applying any one of several distinct sets of access rules. The firewall can also be configured to utilize "stateful" packet filtering which involves caching rule processing results for one or more packets, and then utilizing the cached results to bypass rule processing for subsequent similar packets. To facilitate passage to a user, by a firewall, of a separate later transmission which is properly in response to an original transmission, a dependency mask can be set based on session data items such as source host address, destination host address, and type of service. The mask can be used to query a cache of active sessions being processed by the firewall, such that a rule can be selected based on the number of sessions that satisfy the query. Dynamic rules may be used in addition to pre-loaded access rules in order to simplify rule processing. To unburden the firewall of application proxies, the firewall can be enabled to redirect a network session to a separate server for processing.

Abstract translation: 本发明提供了改进的计算机网络防火墙，其包括用于提高处理效率的一个或多个特征。 根据本发明的防火墙可以通过应用几组不同的访问规则中的任何一种来支持多个安全策略，多个用户或两者。 防火墙还可以配置为利用“有状态”包过滤，其涉及缓存一个或多个数据包的规则处理结果，然后利用缓存结果绕过后续类似数据包的规则处理。 为了便于通过防火墙向用户通过适当地响应于原始传输的单独的后续传输，可以基于诸如源主机地址，目的地主机地址和类型的会话数据项来设置依赖性掩码 服务。 该掩码可用于查询正在由防火墙处理的活动会话的缓存，以便可以基于满足查询的会话数选择规则。 除了预加载的访问规则之外，还可以使用动态规则，以简化规则处理。 要卸载应用程序代理的防火墙，可以启用防火墙将网络会话重定向到单独的服务器进行处理。

Abstract: A teleconferencing system in which a teleconference controller advantageously uses information relating to the network topology layout of remote nodes which are to participate in a teleconference, and then advantageously directs the transmission of video and/or audio streams from a source node to an identified subset of the remote nodes based on the capabilities of the nodes and the network links. These nodes which initially receive the video and/or audio streams then advantageously forward the streams in turn to other nodes in their vicinity using peer-to-peer network connectivity techniques. The identification of the subset of nodes which serve as peer-to-peer forwarding nodes may be based on node activity, node service capacity, the impact on network links between the node and the requester, the distance and/or latency between the node and the requester, and the ability of the node to meet requests including video transcoding requests.

Abstract: A multi-media method, system and apparatus are provided to optimize a network bandwidth and enhanced video experience. Each of a plurality of environmental views are encoded and the encoded multi-media streams are subsequently transcoded in accordance with respective encoding characteristics. The resulting video streams are then provided to a user for selecting preferred views. The user's multi-media preferential attributes are determined from the viewer's feedback. In response to the viewers' feedback, a video manager communicates to the cameras/encoders encoding characteristics and to the transcoders transcoding characteristics associated with corresponding encoded multi-media streams. A transport processor encodes for transport each of a plurality of the transcoded video streams and communicate towards viewers the transcoded video streams.
