Abstract: In one embodiment, a method for providing communication Forward Error Correction (FEC) optimization for virtualized platforms, comprising: calculating a cut off time used to terminate total FEC processing duration; processing code blocks received in a subframe in an order defined by a sorting stage; and wherein processing code blocks comprises: checking if a current time has exceeded the cut off time cut off value; when the current time has exceeded the cut off time value, then setting a Cyclic Redundancy Code (CRC) FAIL and moving onto a next code block without decoding; when the current time has not exceeded the cut off time value, then running a single iteration of decoding and checking a code block CRC; when the code block CRC is PASS then decoding is successful and moving onto a next code block; when the code block CRC is FAIL then checking if a maximum number of FEC iterations has been reached; when maximum number of FEC iterations has not been reached repeating the steps of calculating and processing code blocks; and when maximum number of FEC iterations has been reached then moving onto the next code block.
