Principles of Communications - week 1/L1 10/10/2019

Aside from a visit from the Amicus Curiae (friend of the supreme court judge:),
L1 started with intro to routing. Refer people to last year's network course, and the lectures on the network.

Slide 3 has a network graph with nodes numbered 1-12, and a routing table for node 1. This is a confusing picture as it has [] against some of the entries (both for some next hops, and some destinations) so a) its a forwarding table, not a routing table; and b) it is showing the outcome of some computation - As far as I can recall, the [] represent where the SPF algo tie broke between two routes. - It is a useful exercise to work through in any case.  On asking the original author of the graph (see his book for the non power point version), they're artefacts/noise and don't actually signify:-)
