Abstract: An improved system and method are disclosed for peer-to-peer communications. In one example, the method includes retrieving a profile and a routing table from an access server by a first endpoint during an authentication process. The profile identifies at least a second endpoint as an endpoint with which the first endpoint has permission to communicate. The routing table contains address information needed for the first endpoint to communicate directly with the second endpoint. The first endpoint sends a notification message directly to the second endpoint using the address information to inform the second endpoint that the first endpoint is online.

Abstract: An apparatus and a method for filtering glitches in a data communications controller receiving asynchronous input data signals varying between two signal levels representing two bit values and having a predetermined input bit period, and sending output data signals corresponding to the input data signals. Glitches are detected in the input data signals by detecting reversals of signal level having a duration less than the input bit period. A glitch time value corresponding to the glitch duration is determined, and then a sampling clock rate is set at a rate determined from the glitch time value. The input data signals are sampled at the sampling clock rate to generate a sequence of input data samples. A voting number of input data samples are monitored and an output signal is provided, representing the value of a majority of the sequential input data samples.

Abstract: An apparatus and a method for filtering glitches in a data communications controller receiving asynchronous input data signals varying between two signal levels representing two bit values and having a predetermined input bit period, and sending output data signals corresponding to the input data signals. The glitches comprise reversals of signal level, having a glitch duration less than the predetermined bit period, on the input data signals. Glitches are detected in the input data signals by detecting reversals of signal level having a predetermined duration less than the predetermined input bit period. A glitch time value corresponding to the glitch duration is determined, and then a sampling clock rate is determined from the glitch time value. The input data signals are sampled at the sampling clock rate to generate a sequence of input data samples.
