Leading the way in IT testing and certification tools, www.testking.com - 2 - CCDA 2.0 CASE 1: FSI Test Equipment Incorporated: Precision test equipment manufacturing FSI manufactures high-end, high-volume semi-custom test equipment. Though the company only employs 150 people, sales revenue and profitability are very high because of niche market control and product price levels. Each piece of equipment is built to order and goes through rigorous testing and integration. As a result of market dominance, growth and profitability, company management has decided to make an initial public offering (IPO) of its stock. FSI has customers through out the world. Because their equipment integrates so tightly with customers’ high tech manufacturing systems, the company in reality becomes a partner with its customers during the design, manufacturing, and testing of the equipment. Purchase order to operational date cycles are typically one year and approximately five systems are in the development cycle at any gives time. Timely, accurate, and secure communications with the customer throughout the cycle is in imperative. Hardware design involves a significant number of CAD drawings to be stored and transmitted. Software development requires hundreds of thousands of lines of code for each customer. Though much of the code is reused, it nonetheless requires configuration and revision control for each customer. With funds raised from the IPO, FSI wants to improve its ability to interface, communicate and respond to its customers. It wants to implement secure FTP of code and drawings to its customer. Security is of utmost importance and therefore FSI is not sure if can trust the Internet to accomplish these transfers. Because of financial concerns, the company would much prefer the Internet to a private network if it can be convinced that the transfers can be made secure. Otherwise it will consider a private network. The company also would like to implement an inter-company workflow system for routing of electronic forms between FSI and its customers world-wide. Again, security is the issue. It would be wonderful if they can use the Internet for both these functions, but the new board of directors must be convinced. FSI offices are in San Jose, California. The project team assigned to customers has two sub-teams: the manufacturing and development team in San Jose, and the integration teams moves on site to the customers’ facilities. Communication is by telephone, e-mail, and even overnight package delivery. 25% of FSI employees (38-40) people are housed at customer sites at any given time. These field persons are in teams of approximately 8 people. A Novell PC LAN on Ethernet is established for each team within the customers’ facilities with a dial-up Internet connection using Livingston router for e-mail. In the San Jose office, FSI has two LANs with 80 PCs. The main LAN has 5 sun AutoCAD workstations that will use the test software, 20 Pentium UNIX engineering workstations for software development on one segment, and 50 office automation desktops running the Lotus Suite on another segment. These two LAN segments are connected to a Novell server with the two Ethernet cards as the only routing mechanism between the two. The second LAN has five processes monitoring an analysis PCs that collect and analyses the test data. This data is accesses continuously by the engineering staff from their workstation. The two LANs are networked with a third Internet card in the Novel server. Engineering staff is frequently frustrated with the performance across this link. You have been asked to provide a design and justification for an intranet/Internet bases solution that will convince the board of directors that the solution is viable and secure. CASE 2: EIC Satellite Systems: Digital satellite television programming sales EIC sells minidish satellite systems and television programs in central Europe. Its sales network comprises 10 company owned offices, 25 distributed sales and installation offices Leading the way in IT testing and certification tools, www.testking.com - 3 - CCDA 2.0 and a central office in Milan, Italy. In the central office 75 representatives provide 24 hour telephone support and order processing for programming changes. There are 200 employees in the central office with PCs running Microsoft Office in addition to telephone representatives. The company’s order processing, billing, accounting and programming systems reside on a large AS400 system in Milan. The 10 company offices are connected to this system with 9600bps leased lines. 25 distributor offices dial in to the system twice a day to upload order and download installation work order. An Ethernet LAN with three Novel servers supports the 275 central office employees. On average, the 10 offices have 4 PCs connected via Ethernet with Microsoft Windows 95. The leased line in each office does not provide a touted connection but a serial connection of 5250 terminal emulation to the communication port on the PC. The 25distributer offices dial in to the three PC Anywhere remote control computers that run 5250 terminal emulation and scripts that download installation work orders and upload new account orders to the AS400. To reduce transaction processing coast EIC will implement intranet technology to replace the current data communication mode. A Web server will be installed on the AS400 with back-end CGI that will interface to the order processing, billing and work order system. Java applets will be built for both remote PCs. EIC anticipates that these changes will allow it to handle twice the transactions without upgrading the AS400, while maintaining current transaction processing times. The company offices will be connected via ISDN routers using bonding between channels for the new browser-based applications. Similar browser-based connections will be accomplished for the distributor offices using a direct dial to the EIC Milan main office. Unless convinced otherwise, EIC intends to use the existing 9600bps lines for the routed connections. It is also desirable to provide an in Internet dial-up connections for customers to make their own configuration changes online and to order pay-per-view programming. Security for these transactions will be provided by secure Web transactions. Data transmission encryption is not necessary because these basically are secure Web-based credit card transactions. EIC would like a design and proposal from you to provide the networking for this new architecture that must be implemented in parallel with current operations. CASE 3 Orchard Leasing Corporation: Office building leasing and facilities management Leading the way in IT testing and certification tools, www.testking.com - 4 - CCDA 2.0 Orchard Leasing is a contract leasing and facilities management company with headquarters in Denver, Colorado and offices in Houston, Texas, Atlanta, Georgia, Minneapolis, Minnesota, Chicago, Illinois. Orchard contracts with owners to provide leasing, maintenance and management of high-density office buildings and building complexes. A local office is maintained in one building in each of the cities. The company’s superior service and creative and aggressive marketing has lead to very rapid growth in each of the Orchard’s marketplaces. In fact, Orchard has just signed contracts for four buildings in London, England and three buildings in Frankfurt, Germany. However this growth has out stripped Orchard’s ability to keep up with administrative tasks associated with business, and management is very concerned about its ability to continue to provide the same level of service, given the two new international contracts. Each of the offices has historically maintained its own operation center including a Windows NT file server with leasing, marketing, maintenance, and facilities management (including billing) software, as well as standard office productivity software provided by the WordPerfect suite. The business applications are all custom are all custom applications developed in Access and Visual Basic. Each office has an Ethernet network on 10BaseT cabling. The leasing and marketing software systems run on Apple Macintosh and maintenance and facilities management runs on Intel-based PCs. Typically, there are five PCs and two Macintoshes in an office. The Denver office has six PCs and three Macintoshes but will increase those numbers to ten PCs and six Macintoshes after the proposed upgrades. Data is consolidated monthly in an office report sent by e-mail via the Internet to the home office in Denver. This Internet connection is by way of local ISP on a dial up connection. With the addition of the London and Frankfurt offices, Orchard had decided to consolidate a Leading the way in IT testing and certification tools, www.testking.com - 5 - ... - tailieumienphi.vn
