2.6. Again refer to the following figure. Each ring is labeled approximately at its center from the set{, , , ,e. Each ring represents an autonomous system (AS) 2.6.1. What is meant by the term autonomous sytem? 2.6.2. For each AS, where would you place one or more firewalls? 2.6.3. Assume that the maximum throughput of each segment is relatedto the metric (weight) associated with each segment as follows: 1 1 Tbit sec-1, 2 100 Gbit sec-1, 3 10 Gbit-sec-1, 4 1 Gbit sec-1, and 5 100 Mbit-sec-1. Given where you have placed each firewall in 3.2, what sort of throughput would you want for each firewall so that there would be neither packet loss nor any packets going without inspection? If you cannot answer 3.2, identify the nodes that are present on multiple ASs and use these nodes to answer this question. 2 5 4 2 4 3 Figure 1: A set of intersecting rings
