In the byte stream it provides every byte a unique sequence number. The sequence number field in the TCP header indicates the position in the byte stream of the first byte in the TCP data field. Example: If the sequence number of the first byte in the byte stream is 1000 and this is the first segment, then the sequence number of this segment will be 1000. If the segment is 500 bytes long then the sequence number of the next segment will be 1500 and so on. https://tools.ietf.org/html/rfc793#page-15 15 votes 15 votes Cruzer commented Jul 26, 2019 reply Follow Share In Datalink Layer sequence number is assigned to every frame whereas in TCP sequence number is assigned to every byte in segment. So option a is correct. 0 votes 0 votes Please log in or register to add a comment.
Best answer 31 votes 31 votes a) it should be bytehttp://www.industrialethernetu.com/courses/202_2.htm Parul Agarwal answered Jan 5, 2015 • selected Mar 20, 2015 by Arjun Parul Agarwal comment Share Follow See all 3 Comments See all 3 3 Comments reply CheeseCuBES commented Feb 1, 2021 reply Follow Share why not segment? 0 votes 0 votes mayankorigins25 commented Oct 9, 2021 reply Follow Share I think message is correct answer because tcp count each bytes but it assign one sequence number to each message. For furst message sequence number selected randomly then i inext sequence number depemds on acknowledgement 0 votes 0 votes Abhishek Rauthan commented Jan 12, 2023 reply Follow Share @mayankorigins25 The sequence number is a counter used to keep track of every byte sent outward by a host. so the option A is correct. src:https://www.ibm.com/docs/en/zos-basic-skills?topic=layer-transmission-control-protocol-tcp 0 votes 0 votes Please log in or register to add a comment.
14 votes 14 votes Sending more than 1 byte at a time called message stream. TCP is byte stream in which 1 byte transferred at a time. UDP , SCTP are message stream protocol in which set of bytes transferred at once. refer @Digviajy Pandey answer's https://gateoverflow.in/8425/gate2015-3_22 Prateek kumar answered Oct 21, 2016 Prateek kumar comment Share Follow See all 0 reply Please log in or register to add a comment.
