Abstract
A method and apparatus for transferring data traffic, such as in a SONET/SDH environment, is provided. Two designs are presented, each utilizing a dual device design, where one device performs GFP Framing and the other device performs GFP-T adaptation. The method and apparatus include a first device having a first device FIFO, the first device configured to receive data and assemble data into packets and transfer data across a packet interface when the first device FIFO contains more than N bytes. A second device comprises a second device FIFO, the second device configured to receive data packets from the packet interface and utilize a plurality of thresholds to maintain a quantity of data in the second device FIFO within a predetermined range. Depending on the design employed, control codes, such as 65B_PAD control codes, may be added in the first device under certain conditions to facilitate data transfer.
