A Tsipi segment consists of a segment header and a data section, the TCP header contains 10 mandatory
fields and an optional extension field.
The optional field is the options field, which is the last field seen on the sly.
The TCP header includes a source port and destination port each 16 bits in like.
The source port is the port on the originating machine that emitted the packet.
The destination port indicates the port on the target machine.
The package should be delivered to.
The sequence number and an acknowledgement number allows Tsipi to track a series of packets to make
sure they arrive reliably and pretty much in order.
No, absolutely in order.
If a packet is lost, TCP will retransmit it.
If packets arrive out of order, TCP will adjust them to make sure that they are delivered to the destination
services in the proper order.
Data asset specifies the size of the TCP header in 32 bit words.
The minimum size header is five words and the maximum is 15 words.
There's also TCP control bit space, also known as Flagg's, which are incredibly important for tracking
the state of a given TCP connection.
As you know, we talked about them a few minutes ago.
Of course, if you didn't take a break, it was a few minutes ago.
But whatever you do, just don't spill in the keyboard.
Now, TCP senders use a number called window size, which isn't byte by default.
To regulate how much data they send to a receiver before requiring an acknowledgement in return.
So if the window size becomes too small, network data transfer will be unnecessarily slow, while if
the window size becomes too large, the network link can become saturated or the receiver may not be
able to process incoming data quickly enough, also resulting in slow performance.
Windowing algorithms built into the protocol dynamically calculate size values and use this field of
the TCP headers to coordinate changes between senders and receivers.
