Question

What is the relationship between the variable SendBase in Section 3.5.4 and the variable LastByteRcvd in Section 3.5.5?

Answer

Relationship between the variables, SendBase and LastByteRcvd:

                          SendBase-1 <=LastByteRcvd

Detailed Explanation:

  • SendBase-1 is used to find the sequence number of the last byte(Refer Section 3.5.4 from the text book)
  • LastByteRcvd is used to find the number of the last byte in the stream of data arrival from network to buffer. So, SendBase is the LastByteRcvd at the receiver end.
