    Abstract: Methods and apparatus for testing of Internet-Protocol packet network perimeter protection devices, e.g., Border Gateways such as Session Border Controllers, including dynamic pinhole capable firewalls are discussed. Analysis and testing of these network perimeter protection devices is performed to evaluate the ability of such device to perform at carrier class levels. The efficiency of state look table functions as well as call signaling processing capacity, implemented in a particular perimeter protection device, are determined and evaluated. Proper performance and efficiency of such perimeter protection devices are evaluated as a function of incoming call rate and as a function of total pre-existing active calls. Various different network perimeter protection devices, e.g., of different types and/or from different manufactures, can be benchmarked for suitability to carrier class environments and comparatively evaluated. Test equipment devices, e.g., enhanced Integrated Intelligent End Points (IIEPs), for fault testing, evaluating and stressing the network perimeter protection devices in a system environment are described. Typically these specialized test devices are used in pairs, one on each side of the firewall under test. These test equipment devices include a heavy duty traffic generator module, monitoring and analysis capability including a CPU utilization analysis module, and a graphical output capability.

    Abstract: Systems and methods are described for providing a plurality of communication services over existing access lines such as twisted pair access lines. These services include voice, audio/video, and data communication services, the so-called “triple play” of services. The use of existing communication lines enables these services to be provided at a relatively low cost. Remote terminals are located close to subscriber premises to reduce the length of the existing communication lines connecting subscribers to the network. Data associated with a plurality of communication services may be statistically multiplexed onto the communication lines. Subscribers are provided with the capability to dynamically select services, including the capability to select audio/video signals from a set containing audio/video broadcast signals. The systems and methods enable data to be transported efficiently through the backbone network interconnecting central offices. Capabilities comparable the capabilities of coaxial cable systems are provided at a lower cost than alternative approaches, such as running fiber all the way to the subscriber premises.

    Abstract: Methods and apparatus for wiretapping IP telephone calls are described. At the time an IP telephone registers its current IP address and telephone number with a soft switch responsible for routing calls to the IP telephony device a list of telephone numbers to be monitored is checked. If the number being registered is to be monitored, information identifying the edge router through which the IP telephony device connects to the IP network is obtained. The edge router is then sent a monitor message with the IP address corresponding to the telephone number to be monitored. IP packets including the specified IP address are then forwarded by the identified edge router to a monitoring station. Packet forwarding may involve packet duplication with the original packets being allowed to continue on to their original destination and the duplicated packets being forwarded or, alternatively, a simple packet redirection operation.

    Abstract: PSTN functionality is enhanced by the addition of an external service bridging device (ESBD) between one or more devices, e.g., signal switching points (SSPs), and a service control point (SCP). The ESBD serves as a coupling device to one or more control devices, e.g., other SCPs or IP servers, in addition to the SCP. To support the passing of messages between the SS7 network and the control devices, the ESBD includes message reformatting capabilities. The ESBD monitors for messages directed to SCPs and/or replies to messages directed to an SCP. In response to detecting a message the ESBD checks to determine if the detected message is to be processed or simply forwarded to the SCP. Messages to be processed are intercepted, duplicated, modified, replaced, broadcast, redirected, etc. Replies to broadcast query messages are detected and processed so that a single reply, in the format of an SCP response, is returned.
