1
00:00:00,470 --> 00:00:09,440
A Tsipi segment consists of a segment header and a data section, the TCP header contains 10 mandatory

2
00:00:09,440 --> 00:00:12,380
fields and an optional extension field.

3
00:00:13,420 --> 00:00:18,190
The optional field is the options field, which is the last field seen on the sly.

4
00:00:19,300 --> 00:00:25,500
The TCP header includes a source port and destination port each 16 bits in like.

5
00:00:26,630 --> 00:00:31,340
The source port is the port on the originating machine that emitted the packet.

6
00:00:32,840 --> 00:00:36,360
The destination port indicates the port on the target machine.

7
00:00:36,560 --> 00:00:38,150
The package should be delivered to.

8
00:00:39,670 --> 00:00:46,210
The sequence number and an acknowledgement number allows Tsipi to track a series of packets to make

9
00:00:46,210 --> 00:00:49,500
sure they arrive reliably and pretty much in order.

10
00:00:49,870 --> 00:00:51,420
No, absolutely in order.

11
00:00:52,360 --> 00:00:56,110
If a packet is lost, TCP will retransmit it.

12
00:00:56,980 --> 00:01:03,340
If packets arrive out of order, TCP will adjust them to make sure that they are delivered to the destination

13
00:01:03,340 --> 00:01:05,230
services in the proper order.

14
00:01:07,480 --> 00:01:13,150
Data asset specifies the size of the TCP header in 32 bit words.

15
00:01:14,530 --> 00:01:19,330
The minimum size header is five words and the maximum is 15 words.

16
00:01:20,520 --> 00:01:27,210
There's also TCP control bit space, also known as Flagg's, which are incredibly important for tracking

17
00:01:27,210 --> 00:01:29,610
the state of a given TCP connection.

18
00:01:30,300 --> 00:01:33,150
As you know, we talked about them a few minutes ago.

19
00:01:34,160 --> 00:01:37,230
Of course, if you didn't take a break, it was a few minutes ago.

20
00:01:37,470 --> 00:01:39,800
But whatever you do, just don't spill in the keyboard.

21
00:01:40,590 --> 00:01:46,290
Now, TCP senders use a number called window size, which isn't byte by default.

22
00:01:47,280 --> 00:01:52,830
To regulate how much data they send to a receiver before requiring an acknowledgement in return.

23
00:01:53,890 --> 00:02:00,990
So if the window size becomes too small, network data transfer will be unnecessarily slow, while if

24
00:02:01,000 --> 00:02:07,720
the window size becomes too large, the network link can become saturated or the receiver may not be

25
00:02:07,720 --> 00:02:12,610
able to process incoming data quickly enough, also resulting in slow performance.

26
00:02:14,600 --> 00:02:21,650
Windowing algorithms built into the protocol dynamically calculate size values and use this field of

27
00:02:21,650 --> 00:02:25,820
the TCP headers to coordinate changes between senders and receivers.
