Patent ID: 7653719

Claim:
A channel bandwidth detection method, comprising: sending a first plurality of data packets from a first endpoint to a second endpoint, where size and number of the first plurality of data packets are based on a first specified channel bandwidth range; and setting a first-endpoint-to-second-endpoint channel bandwidth value to the first specified channel bandwidth range if the first bandwidth range accept value indicates the transmission metrics associated with the first plurality of data packets corresponds with the first specified bandwidth range, else sending a second plurality of data packets from the first endpoint to the second endpoint where size and number of the second plurality of data packets are based on a second specified channel bandwidth range, wherein at least one of the size and the number of the first plurality of data packets is different from the size and the number of the second plurality of data packets receiving, at the first endpoint from the second endpoint, a first bandwidth range accept value indicating whether transmission metrics associated with the first plurality of data packets corresponds with the first specified bandwidth range; and setting a first-endpoint-to-second-endpoint channel bandwidth value to the first specified channel bandwidth range if the first bandwidth range accept value indicates the transmission metrics associated with the first plurality of data packets corresponds with the first specified bandwidth range.
