How is a TCP connection established?

How is a TCP connection established?

To establish a connection, TCP uses a three-way handshake. Before a client attempts to connect with a server, the server must first bind to and listen at a port to open it up for connections: this is called a passive open. ACK: Finally, the client sends an ACK back to the server.

How is a change in IP address handled?

Changing your Internet IP address When connecting to the Internet over a dial-up modem, your ISP assigns your computer a different IP address each time you connect. If you want to change your IP address, try disconnecting and reconnecting. If you’re assigned the same address, disconnect for a few minutes and reconnect.

What is keep-alive in TCP?

The TCP Keepalive Timer feature provides a mechanism to identify dead connections. When a TCP connection on a routing device is idle for too long, the device sends a TCP keepalive packet to the peer with only the Acknowledgment (ACK) flag turned on.

How is a connection maintained over a changing IP address?

In connection oriented protocol, a logical channel is established between the peers before exchanging data. So, if the IP address is changing, it has to tear down the existing connection and re-establish the connection which obviously is disruptive.

Do you have to change your TCP / IP settings?

If you use DHCP, then you don’t have to change your TCP/IP settings if you move your PC to another location, and DHCP doesn’t require you to manually configure TCP/IP settings, such as Domain Name System (DNS) and Windows Internet Name Service (WINS). Select Start , then select Settings > Network & Internet . Do one of the following:

How is a TCP connection bound by IP address?

TCP is a connection oriented protocol that uses stream socket. It is bound by IP address and port number at both the endpoints. In connection oriented protocol, a logical channel is established between the peers before exchanging data.

What happens to the segments of a TCP packet?

TCP will send the segments to layer-3 (IPv4 or IPv6). IP will encapsulate the TCP segments into IP packets. The IP packet headers will contain the source and destination IP addresses. IP will send the IP packets to layer-2, e.g. ethernet.
