How did gaia.cs.umass.edu determine the value used in the Acknowledgment number field? Group of answer choicesThe value of the ACK number field is the sequence number of the next expected byte of data to be received at the server on the client-to-server direction of this connection -- one higher that the sequence number used as the sequence number in the initial SYN segment sent from client to server.Since no payload data has yet to be transmitted, there is no data to be ACKed, and so the value in this field is not important.Since no payload data has yet to be transmitted, there is no data to be ACKed, and so the value in this field is 0.

How much data does the receiver typically acknowledge in an ACK among the first ten data-carrying segments sent from the client to gaia.cs.umass.edu? Group of answer choicesEach acknowledgment acknowledges exactly 1448 bytes of payload data.Some ACKs acknowledge zero bytes of data (these are negative ACKs) and some ACKs acknowledge 1448 bytes of data.Some ACKs acknowledge 1448 bytes of data (corresponding to a single segment), and other ACKs acknowledge 2896 bytes of data (corresponding to two segments)

Which field in a Transmission Control Protocol (TCP) header provides the next expected segment? Data offset Sequence number Checksum Acknowledgement number

TCP sequence numbers and ACKs (1). Consider the TCP Telnet scenario below (from Fig. 3.31 in text). Why is it that the receiver sends an ACK that is one larger than the sequence number in the received datagram?Group of answer choicesBecause TCP sequence numbers always increase by 1, with every new segment, and the TCP receiver always send the sequence number of the next expected segmentBecause the send-to receiver segment carries only one byte of data, and after that segment is received, the next expected byte of data is just the next byte (i.e., has an index that is one larger) in the data stream.

Which segment is sent by the client to synchronize sequence numbers during the three-way handshaking process?ACK segmentSYN + ACK segmentFIN segmentSYN segment
