Digital Communications II Progress by 1.11.2009

This week I'm doing routing - I've updated the material so please check the new version of slides - DAR + DV/LS is a bit tidier (I hope) but if you spot errata, let me know!

lots of stuff for supervisions and exam questions now.

Digital Communications II Progress by 23.10.2009

We have now covered the material in Section Two of the course

Part 2 - Philosphy/Design

Systems, lecture 5
Layering, lecture 6
Implementation, lecture 7
Alphabet Soup, lecture 8

So I talked about user land and kernel implementations, concurrency and OS problems, and finally about what IP and TCP (and ICMP packets look like

A very nice reference for this last bit is W RIch Steven's fine books
TCP/IP Illustrated volumes 1 (operations of protocols) and 2 (walkthru of code!)

Digital Communications II Progress by 16.10.2009

By the end of this week, I will have covered the historical review of
telephone nets (circuit switched, voice networks), basic Internet technology (packet switched, datagram networks) reminders, and the comparison with B-ISDN and Asynchronous Transfer Mode (Cell Switched, virtual circuit) Networks.

From Monday 19th, til end of next week, I'll be covering
systems design in general, layered protocol designs, specifically, a quick
overview of different implementation strategies, and then a very quick tour through the immensely thick alphabet soup of protocols - all of Part II (hopefully!) on
