TAILIEUCHUNG - Lab Scenario 2

Archimedes and Sons, Inc. is a developer and distributor of science and mathematics training programs aimed at community colleges and technical schools. Rather than provide CD-ROMs, which the technically-adept students tend to copy prolifically for their friends (thereby depriving A & S of their revenue), the firm provides interactive web-based training to user accounts (which are still abused, but less so). The high demand for A & S's training comes from their intensive use of animated, three-dimensional graphics which show the pieces of a solution coming together into a whole, and three-dimensional models of complex structures. These graphics are not downloaded to the student; the student. | CertificationZone Page 1 of 3 Date of Issue 06-01-2001 Lab Scenario 2 by Annlee Hines The Scenario Proposal 1 Cost of proposal 1 Proposal 2 Cost of proposal 2 Analysis Proposal 1 Proposal 2 Solution Note for the Financially Astute The Scenario Archimedes and Sons Inc. is a developer and distributor of science and mathematics training programs aimed at community colleges and technical schools. Rather than provide CD-ROMs which the technically-adept students tend to copy prolificacy for their friends thereby depriving A S of their revenue the firm provides interactive web-based training to user accounts which are still abused but less so . The high demand for A S s training comes from their intensive use of animated three-dimensional graphics which show the pieces of a solution coming together into a whole and three-dimensional models of complex structures. These graphics are not downloaded to the student the student sends commands such a rotation or skew to the server which generates and sends the video images as they are created. Business has been growing rapidly and customers are beginning to complain about the speed of response to commands. A S knows the problem is not in the servers when the programs are run locally they are as fast as ever. While nothing can be done about the students end of a connection A S has decided to upgrade its WAN connections to the Internet. A S currently has three T-1s feeding their ISP on a loadsharing connection traffic is shared across all three T-1 lines connections are not discretely tracked running Frame Relay. Each T-1 costs 2650 month they lease their edge router for 215 month. Global Networks A S s carrier has responded with two proposals Proposal 1 Proposal 1 is to increase A S s bandwidth by doubling the number of T-1s and running a compression algorithm on the video before streaming it over Frame Relay. Their existing edge router does not have the capacity to support this higher load so they must buy or lease another one .
