Leave a Comment / CCNA / By

Learn how to do Error Recovery and Reliability in this TCP provides for reliable data transfer, which is additionally called reliability or error recovery, counting on what document you read. To accomplish reliability, TCP numbers data bytes using the Sequence and Acknowledgment fields within the TCP header. TCP achieves reliability in both directions, using the Sequence Number field of 1 direction combined with the Acknowledgment field within the opposite direction. Figure 5-7 shows an example …
