Assignment Help:

Q. TCP – numbering bytes?

  • Numbering is utilized for flow & error control
  • Segments aren't numbered only bytes
  • Full-duplex connection - numbering is independent in each direction
  • Numbers generated arbitrarily from 0 to 2^32-1

Sequence number

- The number of the initial byte carried in the segment

Acknowledgement number

- To confirm received bytes

- Defines the number of the subsequent byte the party expects to receive

- Cumulative
