Introduction to TCP/IP and Sockets, part 1: Introducing the protocols and API

[@tabeebrahman4843]

this video was amazing. the explanations are clear and has given me the most perspective when it comes to the socket programming. most of the other videos out there assume the viewer has much more knowledge then what your video does, its almost like psuedo code for socket protocols, super understandable and fairly comprehensive.

[@reverse_shell]

Rhymu, absolutely loved the video! The diagrams aren't so scary once you've explained them. I am heading to the second video now! :D

[@rhymu]

I'm glad you liked it!

[@ali51717]

As a game developer concerned mostly with cpp. this is a fantastic video and I am very glad I found your channel. I just want to say special thanks for the time you put into those videos, the production quality, slides, and animations, I know they take way more time than the recording itself, so allow me again to say thanks.

[@rhymu]

Thank you so much! I enjoy making these videos, and just wish I had more time to spend on them.

[@ali51717]

@@rhymu I couldn't follow the second video, ( I am completely new to network programming and I Just saw your video, and I understand now how to TCP works but I felt the next part was little advanced to me, May i Know any good resources you think that will enable me to understand the next part? I am already reading through the rfc you mentioned and it all looks good.

[@rhymu]

@@ali51717 I fear that I made the difficulty ramp too steep between these two videos. I should have made a video in between that perhaps gets a little into the code but not so advanced. Thank you for the feedback! I think if you feel ready for it, either the POSIX threads or WinSock documentation pages would be good to guide you towards the programming aspect. A good starting point might be here: docs.microsoft.com/en-us/windows/win32/winsock/getting-started-with-winsock

Best networking video on KZbin. Thank you for creating this series.

[@trenholmelodge1820]

Just amazing. How come he is so clear and easy to understand..Others should follow his technique.

[@AnantaAkash.Podder]

By far the BEST Explanation about SOCKET... Everyone is just saying Socket is just Ip address+port... But it is very Ambiguous... You just Explained it very well... Socket is nothing but An API... Through which my Web Application Code talks to Kernel & thus tells kernel to do some stuffs with all the Protocols... Thank you very Much Sir...❤️❤️❤️

[@2NormalHuman]

this is the best explanation of computer networks that i could find on youtube, thank you for your work

[@idamjelde2776]

This is good! And I like that you have the sections with titles, so that it is easier to jump back and forth in the video to find what you want. Great work!

I can not explain how much I enjoyed this video! So well explained, I was very confused on this topic

Fantastically explained. Its been so long since i have learned all this in University. This was a nice refresher. Thank you

Amazing, video. Thanks. You are a very concise and clear teacher. You are very good at not bogging down the technical info with too much technical grammar; congrats!

[@7race725]

I am a beginner in embedded systems and not sure that web-programming will be applicable on my job. I've decided to familiarize a little with such stuff like TCP/IP and obtained nothing but a mess in my head. Your videos are really clear and now i see a difference between TCP and IP, lol. In fact, that topic seems to be interesting for me. Thank you very much.

Man... you have just summarized stuffs I learned in two networking courses.. hats off... will you continue the series?

[@rhymu]

I'm glad you liked it! I'm considering making another video exploring some common techniques for constructing and parsing messages sent across the network: JSON, protocol buffers, and serialization techniques in general. If there is some aspect of networking you would like me to consider for a future video, please let me know!

[@hussainigoattv9222]

Man you are a hero! please make web development tutorials on nodeJS

[@rhymu]

I'll let you in on a secret, just don't tell anyone else. :D I know almost nothing about NodeJS! I would be glad to make web development tutorials on NodeJS. However, I will need to study it myself, first. In the mean time, may I refer you to my guru for web development? Check out Chris Griffing and his Twitch stream, where he often demonstrates web development live: twitch.tv/cmgriffing -- He probably can recommend several NodeJS learning resources. In the past, he has already recommended this site which covers web development in general, and has a lot of other learning resources as well: freecodecamp.org/

[@shrutiyn962]

hey great video! had a few questions: 1. You mentioned that sockets are like access point to access the protocol stack, what do you mean by that? why should there be an access point? Whats the need for an access point? 2. Why do we need sockets? if the packet gets the destination IP(from network layer) and the destination port number (from the transport layer) then why do i need sockets in UDP? The packets go through the network and gets routed to the destination right? I understand we need sockets in TCP because its connection oriented and so to establish the connection we need sockets but why in UDP? please correct me if I'm wrong here. I'm having a hard time understanding the concept of sockets and its need. HELP!

[@rhymu]

1. What I mean by access point is a handle or object that an application uses in conjunction with the operating system APIs to send and receive data through a network interface. Think of a socket as analogous to a file handle. 2. You need sockets because a socket is the interface between the application and the operating system for exchanging network packets. Think from the operating system's perspective: "I just got this packet from google.com; which application should I deliver it to?" The answer is the operating system keeps a table of sockets, where each socket is "bound" to a protocol, local address and port number, and is associated with one of the many applications that are running on the host. The operating system inspects the packet to find the protocol, local address and port number, and looks up which socket in its table that maps to. If it finds one, it delivers the packet to the application associated with it. Just like a file or a mailbox. It doesn't matter if it's connection-oriented or packet-oriented. It's about the addressing and binding.

[@kennylee6499]

This was a great video! I’m new to cpp and am interested in learning more about server development in the context of game servers/dev. Do you have any tips/advice on how to go about this? I’m definitely going to check out more of your channel too!

[@rhymu]

This is a very challenging area to study, with many parts to consider. Games can be very demanding when it comes to server requirements; players want low-latency as well as high availability, and games have a rather unique challenge other kinds of servers don't have: keeping the games fair by preventing players from cheating. I'm by no means an expert; I recommend the blogs and presentations made by experts in the field, such as this one about client-side game architecture: www.gabrielgambetta.com/client-server-game-architecture.html If you prefer KZbin content, check out videos such as this one, made by the creators of "Rocket League", which covers some of the challenges and solutions they came up with for the networking aspects of their game: kzbin.info/www/bejne/q5aonpx6gp5nf6c

[@kentmiggalen9756]

nice Tutorial Gilfoyle

[@mindgr13]

Isn't it TCP that divides data into multiple packets and not the IP?

[@alisadm]

Is the Header Checksum the same as the Frame Check Sequence?

[@rhymu]

Yes, the header checksum is specifically the frame check sequence used for these protocols. (Frame Check Sequence being a general term and in the case of TCP/IP the implementation of it is the header checksum).
