- 4. The original HTTP protocol used TCP/IP as the underlying protocol. For each page, graphic, or applet, a separate TCP connection was constructed, used, and terminated. This caused several problems: one referred to as the elephant and mice problem and two aspects of connection overhead. Describe both problems. Why were separate connections used? Would UDP rather than TCP be a good alternative? What solution would you propose to these problems to improve HTTP performance?arrow_forwardAssignment 5: Both TCP and UDP are widely used IP transfer layer protocols. For applications requiring reliable transfers, TCP is generally preferred, while applications that value throughput more than reliability are best served using UDP. Most TCP/IP stacks provide both protocols, so the application can use whichever transfer protocol is more appropriate, even changing from one to the other as desired. Rather than rely solely on TCP, the network system developer might want to investigate the trade-offs related to use of UDP. Based upon the analysis list out why Some TCP/IP Applications Use UDP?arrow_forwardPlease type the ans Imagine you are the network administrator of University X having N campuses in alaska. You want to build a connected network of servers (each server is either a regular or a routing one), one at each campus, and want to choose some of them to be the designated routing servers. A routing server will serve regular servers who connect directly to it via high speed cables, and every regular server must connect to at least one routing server. Your goal is to minimize the total length of high speed cable that you must purchase. Given the geographic locations of the N campuses, design a plan that requires (1) the shortest length of cable and (2) the least number of routing servers. Analyze the time and space complexity of your procedure.arrow_forward
- 1.4-10 Link Utilization (a). Consider the scenario below where 4 TCP senders are connected to 4 receivers. The servers transmit to the receiving hosts at the fastest rate possible (i.e., at the rate at which the bottleneck link between a server and its destination is operating at 100% utilization, and is fairly shared among the connections passing through that link).
