Three types of switching fabries have been learned. List and briely describe each type. Which, if any, can send multipke packets aross the fabrie in parallel? 3. Do routers have IP adkdresses? If so, bow many? L. Suppose an application generates chianks of 40 bytes of data every 20 msec, and each chunk gets encapsulated in a TCP segment and then an IP datagram. What percentage of each datagram will be overhead, and what percentage will be application data? 5. Compare and contrast link-state and distance-vector routing algorithms 6. Discuss how a hierarchical organization of the Internet has made it poesible to scale to millions of users. 7. Is it eessary that every autopomous system use the same intra-AS routing algorithm? Why or why not? 8. Define and contrast the following terms: suboet, prefix, and BGP route. 9. Describe the design principle of Traceroute software. 10. True or False. When an OSPF route sends its link state information, it is sent only to those nodes directly attacbed neighbors. Explain 1. What is the count to ininity problem in distanoe vector roating 12. Is it cessary that all autonomous system use the same intra-AS routing algorithm? Why or why not? 13. what is meant by an in a OSPF autonomous system? Why was the concept of an are a introduced? Question 2. Suppose two packets arrive to two different input ports of a router at exactly the same time. Also suppose there are no other packets anywhere in the router Suppose the two packets are to be forwarded to two different outpat ports, Is it possible to forward the tw packets through the switch fabric at the same time when the fabric uses a sbared bus? packets through the switch fabrie at the same time when the fabeie uses a crossbar? through the switch Eabric at the same time when the fabric uses a crossbar .Suppose the two packets are to be forwarded to two different output ports. Is it possible to forward the two . Suppose the two packets are to be forwarded to the same output port. Is it poesible to forward the two packets Question 3. Consider a router that interconnects three subnets: Subaet 1, Subnet 2, and Subnet 3. Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.1.1724. Also suppose that Subnet 1 is required to support at least 60 interfaces, Subaet 2 is to support at least 90 interfaces, and Subect 3 is to support at least 12 interfaces. Provide three network addresses (of the form a.b.cdfx) that satisfy these coestraints. 11:05 PM 11/5/2017 Type here to search
