The analogies in this series are so good! These explain the concepts with so much clarity!! Thanks for making these public.
Professor Kurose, Looking forward to watch all the lectures .
Thank you for the lectures Professor! Amazing videos.
Easily understand to grasp this knowledge! Thanks, Prof!
I'm looking forward to buy the 8th edition of your book.
You're a legend Dr Kurose
thank u so much for helping me understand this chapter so well!! I was struggling with the network course and may take another one!!🥰
Thank you Sir , It is very useful for me.😇
Thank you professor:DDD

@@cenkerenozbek W.W.. wonder what it might mean? Wudrow Wilson?
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
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.
I strongly agree...
which slide you use to teach us then from where we download
What is the processes here?
Professor Kurose, it was a very good discussion! How can we get access to all videos of the course?

Basic concepts of transport layer and it's purpose :)
🎯 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.*
