Module 7 - CST 311

This week we began our exploration of both the link layer as well as network security. It was very interesting to look into the operation of the link layer, which lies partly in software and partly in hardware. It was quite interesting to listen through the lecture on network security, and the chapter 8 assignment was a little tricky but very informative. The lab this week focused on Ethernet and ARP which were quite interesting to see in action. I am looking forward to the final week and will continue to prepare for the final this weekend.

Module 6 - CST 311

This week was quite interesting as we continued our foray into the networking layer. I really enjoyed the lab this week where we worked with ICMP messages to check targets on the other side of the world. I repeatedly was unable to reach the provided University in Hong Kong and so used a University centered in Tokyo instead for the first half of the lab. It was quite interesting to learn about the Algorithms used in routing and to practice using them on a very small scale in the assignment. There was one things I found confusing in the quiz this week with the fragmentation of the IPv6 addresses as I thought fragmentation was possible as long as it was done in the ends of the system, I will continue to research this in my spare time this week. I look forward to the last few weeks and the final exam.
