Abstract:
1. A method of managing a receive buffer in a receiving communications terminal, wherein the receive buffer comprises a data memory organized into a plurality of individually addressable data words and into a plurality of segments, each of the segments is larger than one addressable data word but smaller than a maximum frame size, the method comprising: receiving a frame of data from an originating communications terminal; storing the received frame of data in the receive buffer beginning at a selected segment of a group of reserved segments; releasing a number of the reserved segments equal to the number of segments in a maximum frame size less an actual number of segments occupied by the received frame; in response to a determination that a number of unreserved segments available in the receive buffer after storing the received frame is larger than the maximum frame size, sending a frame buffer available notification to the originating communications terminal and reserving a number of segments in the receive buffer equal to the maximum frame size; and encoding a starting address of the selected segment as an encoded frame start address.
