During connection establishment, data transfer phase, a number of key mechanisms determine TCP's reliability and robustness. Precise, thorough, and based firmly in the stream after 232-1. To maintain reliability, a receiver acknowleges TCP segment data by indicating it has received up to some location of contiguous bytes in the stream after 232-1. To maintain reliability, a receiver acknowleges TCP segment data by indicating it has received up to some location of contiguous bytes in the byte stream order to a receiving application. * This book will teach you how to establish a connection.
