3.1 Introduction and Transport-layer Services

[@karankap00r]

The analogies in this series are so good! These explain the concepts with so much clarity!! Thanks for making these public.

🎯 Key Takeaways for quick navigation: 00:00 📡 *The transport layer is a crucial component of internet architecture, addressing challenges like reliable communication over potentially corrupt channels.* 01:27 🔄 *Study of transport layer involves principles such as multiplexing, demultiplexing, reliable data transfer, flow control, and congestion control.* 02:50 🏠 *Logical communication between application processes on different hosts is a key focus, despite the physical distance and potential issues in the network.* 04:55 📨 *Analogy: Internet hosts are like houses, processes are like kids, application messages are like sealed letters, and the network layer is the Postal Service.* 06:30 🚚 *Transport layer actions include creating segments, determining header fields, passing segments to the network layer, receiving segments, checking headers, extracting messages, and demultiplexing.* 06:42 🔄 *TCP (Transmission Control Protocol) provides reliable, ordered delivery with congestion and flow control, requiring connection setup at sender and receiver.* 07:23 🔄 *UDP (User Datagram Protocol) is a best-effort, no-frills protocol with unreliable delivery and the absence of services like guaranteed delivery time or bandwidth.* Made with HARPA AI

Dear Jim Kurose I really do hope that you will read this message. I really appreciate your work on all covered topics, the structure of materials and insane way of availability for students. My uni (PJ academy) just used your whole presentations and a course to teach us Computer Networking. I really like your teaching style, all those smiley faces which really make your studuing upbeat! But the problem is that our schedule of tests from other subject is so tight that it is even hard to cover all needed materials for our upcoming theory test. And now i am forced to rush from 2nd to 3d course without studying but just preparing for the test. Sadly but it is a usual practice to sometimes not to teach us the actual subject but how to pass the test...

[@byte_easel]

a great analogy indeed. definitely cleared up what the transport vs network does. network layer is to get from point A to point B, transport is figuring out who in point B to deliver to... which is why transport has port numbers, and network has IP addresses. amazing lol

Professor Kurose, Looking forward to watch all the lectures .

[@ikbenlhmnn8421]

Easily understand to grasp this knowledge! Thanks, Prof!

You're a legend Dr Kurose

[@TheJynx2011]

Thank you for the lectures Professor! Amazing videos.

[@bayan445]

thank u so much for helping me understand this chapter so well!! I was struggling with the network course and may take another one!!🥰

[@caetanomf]

I'm looking forward to buy the 8th edition of your book.

Thank you for the video presentations Professor! My answer to the end-of-session question is that "complexities on the edge", it's not a necessity for all applications to provide delay/bandwidth guarantee, so we might leave these issues to the application layer to handle, as we've seen in the example of video streaming services.

[@shishankrawat2105]

I strongly agree...

[@priyeshtandel2101]

Thank you Sir , It is very useful for me.😇

[@onurcanisler]

Thank you professor:DDD

Professor Kurose, it was a very good discussion! How can we get access to all videos of the course?
