2. Telnet is a popular application-layer protocol sed for remote login, and it runs over TCP. Suppose Host A, the client, initiates a Telnet session with Host B, the server Each 1-byte character typed by A will be sent to B; B will send back a copy of each character, which will be displayed on A's screen. This "echo back" is used to ensure that the characters seen by the client A have already been received and processed at the remote site. Each character thus traverses the network twice between the time the client A hits the key and the time the character is displayer on A's monitor Now, assume that A and B establish a TCP connection, using starting sequence num- bers 62 at A and 89 at B. Draw timing diagrams for the following two scenarios . A types a single letter "H". After a few seconds fter A types "H", it types the letter "T" t Please clearly indicate what is put in the sequence number, the ACK, and data fields of the segments 2.
