摘要： An object-forwarding device can block a malicious Content Object from being inserted into an Interest's reverse path over a named data network. During operation, the device can receive a Content Object via a first interface, and can perform a lookup operation in a Pending Interest Table (PIT) to identify a PIT entry for an Interest associated with the Content Object. The device then determines, from the PIT entry, an egress interface used to forward the Interest. If the device determines that the egress interface of the PIT entry matches the first interface for the Content Object, the device forwards the Content Object via a return interface specified in the PIT entry. On the other hand, if the egress interface of the PIT entry does not match the first interface for the Content Object, the device can block the Content Object.

摘要： In a fixed channel wireless network system with a limited number of channels, assignment of the fixed channels between remote client elements and access elements is made systematically according to a set of criteria according for network loading and interference, then channel assignments are dynamically updated according to a priority to maintain optimal network performance with changing conditions of load and interference. The channel utilization problem is addressed at a system level rather than at a local level by treating the system as a three dimensional color mapping problem. All noise is treated as having a source in virtual access elements with an appropriate performance metric. The performance metric is used to select a channel set that minimize chances of interference and maximize user performance. Specifically, there are several parameter matrices which are managed and updated by a central resource management element, namely signal strength between elements, interference, and load. These matrices are used to find the optimal channel assignments for a predetermined limited set of assignable channels. In one implementation, the channel assignment methodology takes into account the interference associated with access elements operating on a selected channel, as well as the interference or energy that spills over (or is otherwise observable) on physical channels adjacent to the selected channel.

In one embodiment, the method includes receiving a first multicast routing protocol (MRP) message, wherein the first MRP message is a request to join a multicast group of receivers. The first MRP message is translated into a second MRP message, wherein the second MRP message is a request to join the multicast group of receivers to which data is being provided by a specific source. The method could be performed by a router contained in a sparse mode network, wherein the sparse mode network is coupled to a source specific mode network that contains the specific source.

摘要： A system and method are disclosed for dividing a network into clock partitions to limit the overhead created by transmitting clock sources. A clock partition can be implemented through several methods. A first method turns off the clock topology exchange on ports connected to the nodes outside the partition. A second method appends a four-byte partition identifier to network clock distribution protocol (NCDP) messages. A third method uses private network-network interface (PNNI) peer group identification to determine the clock partition group.

摘要： Provided is a method and apparatus for inband testing of an echo canceller. The apparatus includes a signal generator for generating an excitation signal including a preamble portion and a test portion. The echo canceller receives the excitation signal at a decoder. The decoder differentiates the preamble from the test portion and obtains control information by decoding the preamble portion. A controller configures the echo canceller during testing according to the control information obtained from the preamble portion. A strength of the present invention is that the preamble portion allows precise control of the echo canceller during testing by synchronizing the test control to the location of the preamble. This allows exacting control of the echo canceller during testing to within a single sample time of the excitation signal, e.g., 125 microseconds. The control information includes any of the following: instructions related to the management of the H-register, instructions related to the management of the non-linear processor, instructions related to an adaptation function in the echo canceller, and timing information related to any of the aforementioned instructions. The preamble further identifies the test to be performed on the echo canceller and the type of test portion.

摘要： In accordance with the invention, a method and structure are provided for obtaining a ratio of M/(2.sup.N +K) by feeding various carry-out (and/or complemented carry-out) signals from full-adders back to various frequency control inputs of the full-adders to modify the denominator of the division ratio. By doing this, K additional or fewer counts are accumulated during each cycle. Thus, the denominator can be changed from 2.sup.N to 2.sup.N +K, where K can be either positive or negative to obtain the desired M/(2.sup.N +K) ratio.
