Compare the TCP header and the UDP header. List the fields in the TCP header that are not part of the UDP header. Give the reason for each missing field.

assume that the link layer uses the flag bytes with byte stuffing approach for framing, with the following details: The beginning of a data frame is indicated by the special flag bytes: DLESTX The end of a data frame is indicated by the special flag bytes: DLEETX The special escape bytes DLE are used for escaping accidental occurrences of either the flag bytes or the escape bytes within the data. For simplicity, assume that no other header/trailer information is added to the data.   1. The following byte stream represents data that needs to be framed by the link layer on the sender’s side. Derive the resultant byte stream by adding necessary flag bytes and performing byte stuffing.  PZDLEAFRGSTXGYK   I have this answer but it is wrong    DLESTXPZDLEAFRGSTXGYKDLEETX

TCP MULTIPLEXING AND DEMULTIPLEXING In the scenario below, the left and right TCP clients communicate with a TCP server using TCP sockets. The Python code used to create a single welcoming socket in the server is shown in the figure (the welcoming socket itself is not shown graphically); code is also shown for the client sockets as well. The three sockets shown in server were created as a result of the server accepting connection requests on this welcoming socket from the two clients (one connection from the client on the left, and two connections from the client on the right). mySocket = socket (AF_INET, SOCK_STREAM) mySocket.bind (myaddr, 6189 ); P1 Answer mySocket = socket (AF_INET, SOCK_STREAM) mySocket.bind (myaddr, 5854 ); ♫ transport QUESTION 1 OF 8 network link physical What is the source port # for packet C? www B source port: ? dest port: ?

Are the TCP receive buffer and the client's application buffer same when utilizing HTTP streaming? How do they engage with one another if they don't talk to one another?
