procedure for 3ree way handshake protocol

Host A sends a TCP SYNchronize packet to Host B with sequance number x and tpdu

Host B receives A's SYN.and reply with its own sequnave nuber that is y.

Host B sends a SYNchronize-ACKnowledgement

Host A receives B's SYN-ACK

to establish a conection a client execute a connect primitive specifying the ip address and the port to which it want to connect.

thus from overall discussion we can say that the to establish connetion via 3reeeway host execute unicast message.

please mark if i wrong or right.your feddback i important to me

Host A sends ACKnowledge

Host B receives ACK. TCP connection is ESTABLISHED.

from this it is look like a unicast msg.is not it.3ree way hand shake usage tcp not udp.so answer should be unicast.

Mr. Jitendera, Ur concept is little bit wrong. Three way
handshake process is lyk dis -

we assume a client computer is contacting a server to send
it some information.

1. The client sends a packet with the SYN bit set and a
sequence number of N.
2. The server sends a packet with an ACK number of N+1,
the SYN bit set and a sequence number of X.
3. The client sends a packet with an ACK number of X+1
and the connection is established.
4. The client sends the data.

Watever i think, It wud be UNICAST communication.
