TCP and UDP Control Bits Coded to Reduce Errors and/or Retransmissions

This article is about TCP and UDP transport layer control bits. The aim is to encode some control bits in TCP and UDP headers in order to improve their reliability. This will ensure that some packets that arrive at the receiving side with only bit errors in the header part can be corrected and thus be delivered to the application layer without problem instead of being retransmitted or discarded. This is done by suggesting an adaptive scaling of the source port number and destination port number fields. In the case of TCP, this will provide in some cases, enough bits that will be added to the bits of the Urgent pointer field, Data-offset part, and the reserved field on a quest of a good coding rate.
