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 ?

Each packet causes an ack or a nak to be generated by the receiver, and ack/nak transmission times ... i) 1 1 - e(i/N) Here ack is sent for each packet or only after entire window size (N packets is sent ) ??
