Maximum packet size  = 256 bytes

Segment lifetime = 30 sec

Bits in sequence number = 8

Maximum number of possible sequence numbers using 8 bits = 256.

So, maximum number of bytes that can be uniquely identified = 256 bytes.

Lifetime of a segment = 20 seconds.

So, maximum amount of data that can be sent in 20 seconds = 256 bytes.

Thus,

Maximum data rate per connection

= 256 bytes / 20 seconds = 12.8 Bytes/ Seconds

8 bit sequence no. means a sender can not send more than 2^8 packets in a lifetime and maximum packet size is 256 bytes

so maximum  number of bits  will be 256*256*8=52488 bits

So maximum data rate will be 52488/20=26214.4 bps

TCP operates over a 40 Gbps link. If TCP uses the full bandwidth continuously, how long (in msec) would it take the sequence number to wrap around completely?
