Lectures:
Problem classes, starting from Week 2:
The times of the laboratories, which will be in 3W 1.2A (and not in EB 0.8), are as follows:
CM50123 labs (rehearsals, group Comp/2),CM30078 labs (rehearsals, group Comp/3, note that the lab does not start at 14:15),CM30078 labs (rehearsals, group Comp/4),CM30078 labs (rehearsals, group Comp/1),CM50123 labs (coursework, group Comp/2),CM30078 labs (coursework, group Comp/3, note that the lab does not start at 14:15),CM30078 labs (coursework, group Comp/4),CM30078 labs (coursework, group Comp/1).The official textbook, which I suggest to buy, is:
You might find useful some parts of the book:
You might find useful the course TCP/IP Networking by Jean-Yves Le Boudec and Patrick Thiran.
