摘要： An SVC is established via an ATM switch port, which includes multiple virtual paths (VPs), by associating multiple virtual user-to-network interfaces (UNIs) to each of the VPs. Each of the VPs includes multiple virtual circuit (VC) ranges, each of which corresponds to a different virtual UNI. Each VC range includes at least one VC for control and at least one VC for data transfer. Associating the virtual UNIs to each of the VPs includes mapping each virtual UNI to a corresponding VC range within a VP based on a virtual path index (VPI)/virtual channel index (VCI) of the virtual UNI initially received by the ATM switch port.

摘要： A method and apparatus for testing communications within a broadband network between a network edge device and a customer premises device. Network data traffic is diverted from the customer premises device to a test device. The test device emulates the customer premises device through the use of identifying data associated with the customer premises device. In one embodiment, data is diverted from the customer premises device to a test port loop back converter, which performs a DSL conversion of the data. The converted data is backhauled from the test port loop back converter to a test network edge device. The data is then sent from the test network edge device to a test customer premises device. The test customer premises device can be located at a site remote from the network edge device or can be collocated with and directly coupled to the network edge device.

摘要： An device, called a facilities management platform (FMP) connects current digital and analog carrier networks and packet switched networks of interexchange carriers with high speed multiple access subscriber links implemented over twisted pair lines. The subscriber line is terminated by an access module containing one or more modems. In preferred embodiments, the modems are high-speed digital tethered virtual radio channel or xDSL modems. The FMP interface applies and receives signaling and voice through a digital loop carrier (DLC) via a multiplexer connected directly to the DLC backplane. The multiplexer is controlled by a controller of an access module. It translates data from the subscriber link to the form compatible with the digital backplane to create the appearance of one or more line cards. The FMP also may contain a sound generator to allow it to handle calls through an analog carrier network. The FMP, through the same access module transmits data to and from the modems directly through connected digital networks, such as ATM or SONET, of an interexchange carrier. Through this interface, different network companies can offer competing products through different networks all seamlessly connected through a high speed subscriber line.

摘要： Methods and apparatus for performing admission control and bandwidth allocation from a centralized network location in a communications system which supports various IP based services are described. Admission control is performed based on user interaction with a Web interface hosted by a centralized control. Users may subscribe/unsubscribe to premium (e.g., high bandwidth) services. Admission control to the premium services is controlled by the centralized control. The control interfaces with a gateway (edge) router which implements service decisions. The centralized control maintains a database of the users, links in the network, network elements, and estimates of allocated/free bandwidth on the links. In some embodiments, traffic, not under centralized control, e.g., from business switches and/or legacy gateway routers may be injected onto the network links. Load estimation methods are used to account for bandwidth consumed on the links by this injected traffic.

摘要： A user's set top box (STB), or other client, executes a shell and has an application programming interface (API) by which certain features of the client can be controlled. The client is in communication with a walled garden proxy server (WGPS), which controls access to a walled garden. The walled garden contains links to one or more servers providing network-based services. The client sends a request to the WGPS to access a service provided by a site in the garden. To provide the service, the site sends the client a message containing code calling a function in the API. The WGPS traps the message from the site and looks up the site in a table to determine the access control list (ACL) for the site. The ACL is a bit-map that specifies which functions of the client's API can be invoked by code from the site. The WGPS includes the ACL in the header of the hypertext transport protocol (HTTP) message to the client. The shell receives the message and extracts the ACL. The shell uses the ACL to determine whether the code has permission to execute any called functions in the API. If the code lacks permission, the shell stops execution and sends a message to the site indicating that the site lacks permission. Otherwise, the shell allows the code to call the function.
