摘要： A device associated with the authentication of a user on a network, i.e., an “authentication device,” initiates lawful interception of network traffic associated with the user. The authentication device communicates with a network service device, such as an edge router, providing network access or other services to the user to enable and disable monitoring of the network user. The authentication device may issue intercept requests to the network service device upon authenticating the network user during login or at any time while the network user's session is in progress. Upon receiving an intercept request from the authentication device, the network service device mirrors data packets flowing to and from the network user for which interception has been designated. The mirrored packets are sent to an analyzer, which analyzes the packets and provides packet analysis information to a law enforcement agency.

摘要： Techniques are described for dynamically configuring an interface in a network service provider. The techniques allow dynamic configuration of, for example, a dual stacked interface that includes both Internet Protocol version 6 (IPv6) and Internet Protocol version 4 (IPv4) on the same layer 2 link. In this way, a customer network having an existing IPv4 connection to a network service provider will be able to run both IPv4 and IPv6 over the same interface. A network device within the network service provider may receive a control packet from a subscriber device. The packet may be received on an ATM hybrid permanent virtual circuit (PVC) that supports multiple interface columns. The network device is capable of auto-sensing multiple packet protocols and may dynamically create multiple interface columns over the same ATM interface based on the encapsulation type of the received packets.
摘要翻译：描述了在网络服务提供商中动态配置接口的技术。这些技术允许例如在同一层2链路上包括互联网协议版本6（IPv6）和互联网协议版本4（IPv4）的双重堆叠接口的动态配置。以这种方式，具有与网络服务提供商的现有IPv4连接的客户网络将能够通过相同的接口运行IPv4和IPv6。网络服务提供商内的网络设备可以从用户设备接收控制分组。该分组可以在支持多个接口列的ATM混合永久虚拟电路（PVC）上接收。网络设备能够自动检测多个分组协议，并且可以基于接收到的分组的封装类型在相同的ATM接口上动态地创建多个接口列。
