摘要： A network router includes a set of interface cards to receive packets from a network, and a set of accounting modules to calculate flow statistics for the packets. The router further includes a control unit to adaptively update routing information in response to the calculated flow statistics, and to route the packets in accordance with the routing information. The control unit identifies potentially malicious packet flows for the received packets based on the flow statistics, and applies an intercept filter to intercept the packets of the identified packet flows. The control unit analyzes the intercepted packets in real-time to determine the presence of a network event, and updates the routing information based on the determination, e.g., by terminating routing for packets associated with malicious packet flows. In this manner, the router may adaptively respond to network events, such as network security violations.

摘要： A network device integrates accounting functionality for generation of flow statistics with packet intercept functionality to provide a comprehensive traffic analysis environment. The device comprises a set of network interface cards to receive packets from a network, and a set of accounting service cards to calculate flow statistics for the packets. The device further comprises a control unit to receive the network packets from the interface cards and distribute the packets to the set of accounting service cards. The accounting service card comprises an interface for insertion within a slot of a network device. Accounting service cards may be added to easily scale the network device to support higher bandwidth communication links, such as OC-3, OC-12, OC048 and higher rate links. Additional accounting service cards may be used for purposes of redundancy to support continuous, uninterrupted packet processing and accounting in the event of a card failure.

摘要： A service/device discovery protocol which allows a customer premise device (CPD) to automatically discover other CPDs sharing common service related characteristics, and techniques for self-configuration of the service are described. For example, when a new customer site or CPD is to be added to an existing shared service, the service discovery protocol allows a CPD at the new customer site to automatically discover the other customer sites and/or CPDs associated with the existing shared service. The self-configuration techniques allow the new CPD to automatically configure itself as a member of the shared service, and also allow the existing CPDs to update their service configuration information to include the new customer site and/or CPD.

摘要： A network device may act as a proxy for a client requesting video from a server and may control the quality of the video requested from the server. The network device may detect a negotiation for a video stream, the negotiation including at least a first message from the client indicating a requested video quality by the client; and determine a maximum allowed video quality for the client. The network device may additionally determine whether the requested video quality by the client is greater than the maximum allowed video quality and modifying, when the requested video quality by the client is greater than the maximum allowed video quality, a first message to change the requested video quality to be equal to the maximum allowed video quality.
摘要翻译：网络设备可以用作从服务器请求视频的客户的代理，并且可以控制从服务器请求的视频的质量。网络设备可以检测视频流的协商，协商至少包括来自客户端的第一消息，指示客户端请求的视频质量; 并确定客户端允许的最大视频质量。网络设备可以另外确定客户端所请求的视频质量是否大于最大允许视频质量，并且当客户端所请求的视频质量大于最大允许视频质量时，修改第一消息以改变所请求的视频质量等于最大允许的视频质量。
