    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.

    🎯 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
