Which four 4-tuple parameters will identify a TCP socket?
One subtle difference between a TCP socket and a UDP socket is that a TCP socket is identified by a four-tuple: (source IP address, source port number, destination IP address, destination port number).
What is the four-tuple used to uniquely identify a connection?
The combination of an IP address and a port number is sometimes called an endpoint or socket in the TCP literature. It is a pair of sockets or endpoints (the 4-tuple consisting of the client IP address, client port number, server IP address, and server port number) that uniquely identifies each TCP connection.
How many tuples are there in TCP socket for identification?
5-tuple
A TCP connection is identified by a 5-tuple. That means one tuple, with 5 elements. The five elements are: Protocol.
What are the components of 4-tuple in a TCP socket?
For addressing, TCP and UDP use a 4-tuple of:
- Local IP address.
- Local port number.
- Foreign IP address.
- Foreign port number.
What is the 5-tuple?
5-Tuple: The tuple (source IP address, source port, destination IP address, destination port, transport protocol). A 5-tuple uniquely identifies a UDP/TCP session. When a UDP/TCP session flows through a NAT64, each session has two different 5-tuples: one with IPv4 addresses and one with IPv6 addresses.
What are two of the 5 tuples?
How is a TCP socket fully identified?
In the TCP protocol, the socket is uniquely identified by the source IP, source port, destination IP, and destination port.
How is a socket identified in a TCP protocol?
In the UDP protocol, a socket is uniquely identified by the source IP and the source port. In the TCP protocol, the socket is uniquely identified by the source IP, source port, destination IP, and destination port.
How many tuples are there in a connection?
You’ve misunderstood the terminology. A TCP connection is identified by a 5-tuple. That means one tuple, with 5 elements. The five elements are: Protocol. This is often omitted as it is understood that we are talking about TCP, which leaves 4. Source IP address. Source port. Target IP address. Target port.
Are there two different definitions of a socket?
Unfortunately things get confusing because there are two different definitions of socket out there.
