Sequence number
Two hosts A and B are communicating with each other using TCP. Assume the sequence number field starts at 0 and the receiver employs cumulative ack. A has successfully sent 465 bytes of data which were also acked by B. Suppose A were now to send 3 ... the first and third segment, what will the ack value be in the ack generated as a consequence of receiving this second segment?

Virtual Gate Test Series: Computer Networks - Sequence Number
Consider bandwidth of line is $100$ Mbps and the sequence number of the field consists $32$ bits on a TCP machine. How much time it will take to cover all possible sequence numbers? ________________ sec (integer value only). Mine was $ 343.59$, so $344$ but my answer is wrong.

Computer Networks - Transport Layer - Sequence number wrap around
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?

Data rate per connection in transport Layer
In a network that has a maximum TPDU size of $128$ bytes, a maximum TPDU lifetime of $30$ sec, and an $8- bit$ sequence number, what is the maximum data rate per connection? My attempt: in $30 sec$ we can identify $256 bytes$ because ... giving sequence number to each segment and thus calculating the data rate as $256*128*8$ bits in $30 sec$ or $8.7Kbps$.

Sequence number
When we talk of flow control we provide sequence number to our frames so that duplicate is avoided. But in IEEE 802.3 frame consist of PREAMBLE DEST.MAC SOURCE.MAC TYPE/H.LENGHT DATA PAD CRC which field does hold the sequence number ? or its a wrong question? plz tell me what i am missing in here?

State True or False, Give Reason I) If the sequence number of a transport layer segment is m, then application layer it's sequence number could also be m II) If the sequence number of a transport layer segment is m, then the sequence number of the subsequent segment is always m+1.

TCP sequence number in case of Dummy packet
Hi Guys, I know 1 new sequence number is consumed consumed for SYN, FIN or 1 byte of Data (means for 100 Byte 100 sequence number will be used). But sometimes TCP sends Dummy packet for example when receivers window size is zero ... as Silly window Syndrome problem). So in such kind of cases does new sequence number is used for every dummy packet ?

computer networks - sequence number
Suppose a TCP connection uses a fifteen bit clock to generate starting sequence numbers. The clock ticks for each 0.1 sec and each tick generate a sequence number. The lifetime of a packet 60 sec. If 300 sequence numbers are used by packets for each minute, what is the time for resynchronization of clock? 3261.6 sec 4261.6 sec 5361.6 sec 6433.6 sec
