Rhodes III and members of the network proposal committee, AutoZone provides a great service and customer satisfaction to the United States and other countries in the world. Our goal at Network Design Solutions is to keep Autozone Inc., at the top of the industry. The changes to your network will help your branch offices efficiency, customer service, parts inventory sharing, and sales. It will also expedite the eCommerce efficiency, and improve headquarters to branch communications. Your network will remain fast, safe, and secure for the next five years. With the increase in speed of your network, you can get information to your branches faster and allow for better training by streaming video or online classes that branch members could take from their office. This will increase the knowledge of the branch managers and give them the tools they need to increase sales and adjust their store immediately if the needs arise. The benefits that Network Design Solutions can bring to the AutoZone name and its customers are insurmountable. Together we can make your company’s network run smoother, faster and bring new learning tools to the branch offices. This will in turn help AutoZone to increase stockholder value and keep the company growing. 3 Introduction When choosing a company to collaborate with in business many factors should be involved in the selection process. In this proposal, we will explain why Network Design Solutions is the best company for you. At NDS, we take pride in providing excellence in all aspects of service. This includes customer service, technical support, product installation, and anything else that would make this transaction process as smoothly as possible. We have outlined customer goals and objectives, which we intend to meet. Our researchers have included several different analysis of your current network. These individual reports were included to provide simplicity to all parties involved, so everyone understands fully what is being planned and what will be implemented. A variety of engineers have spent countless hours designing and developing different aspects for this network. We also have provided you with cost analysis reports compiled by a team of consultants and accountants. These reports show how your budget was implemented in the network plan. Each aspect of this network was taken into consideration for the betterment of your needs. Implementation schedules were provided by project managers that have handled such cases as, the restructuring of Atlanta area WANs, and many other big projects. Design templates for each individual location including branches and headquarters were added to this proposal. 4 The biggest concern of most of our customers is the bottom line; Cost. We have detailed spreadsheets with tables containing the cost information for each individual piece of equipment, from Ethernet cables to the Cisco 7206VXR Router, included in the appendix section of this proposal. While network performance is our main focus her at NDS we also realize that cost is very important and that is why we have close to the lowest prices in the business. Several of our business partners include Cisco, Dell, and EMC Corporation. Cisco is the provider of all of our networking appliances at your headquarters facility. Dell is the provider of all of our workstation and printing appliances. Last but not least, EMC is the provider of all of our storage units. We have partnered with the leading competitors in their respective industries to provide you with the best appliances and software packages available to date to deliver reliability, stability and unsurpassed performance. 5 Customer introduction AutoZone is the nation's leading retailer of automotive parts and accessories with more than 3,900 stores in the US, Puerto Rico, and Mexico. Each store carries an extensive line for cars, sport utility vehicles, vans and light trucks, including new and remanufactured hard parts, maintenance items and accessories. Since opening its first store in Forrest City, Ark. on July 4, 1979, the company has joined the New York Stock Exchange (NYSE: AZO) and earned a spot in the Fortune 500. (AutoZone Inc, 2007) Mission Statement AutoZone's primary objective is to maximize long-term stockholder value, while adhering to the laws of the jurisdictions wherein it operates and at all times observing the highest ethical standards. (Investor Relations, 2007) Types of Customers Commercial (dealerships and repair shops) Wholesale (Reman and salvage parts) Retail (in store customers) eCommerce 6 Company Goals and Objectives  Improve the customers’ shopping experience by optimizing the number of both off-shelf merchandise placements and sales floor product placements  Add clarity to our offering by reducing the amount of nonautomotive related items in our stores  Focus on providing our customers with the broadest offering of parts and accessories to meet their ever expanding needs  Renew the emphasis on training our AutoZoners—including a specific emphasis on our Culture  Focus on building “our brands” by expanding coverage under the Duralast family of brands   Reposition our Commercial business for profitable future growth Expand our presence in Mexico and Puerto Rico (Rhodes, 2007) Meeting your Goals and Objectives Our goal is to increase revenue while decreasing the cost of doing business. Our network design will help meet the goals of an increasing demand for eCommerce. Increasing network capacity will insure customers are able to shop online and query your database to insure inventory availability. As the demand for eCommerce grows, your network will scale to meet the demand with minimal investment both in time and money. 7 Smart business entities such as Autozone recognize the growing need to keep repeat business. Making it easier for customers to do business with your organization will most certainly keep customers coming back. In order to meet your first goal our network upgrade will give your customers the ability to query your database to determine availability of parts at each branch store, thus saving them travel time to a store that may not house the particular part they seek. Our network design will give each branch office the same functionality, which can help re-direct customers to the appropriate store as needed. With the increased network capacity, you will be able to push out video streams in order to meet your fourth goal. Most will say, “a picture is worth 1000 words.” Watching videos will make your staff more knowledgeable. In addition, you may be able to market this product to train customers and profit as a result. Our network design will also help increase your product standing resulting in a higher recognition, and higher profit. A network upgrade can help you meet your 5th goal. We have designed your network for scalability. As such, you will be able to reposition your commercial businesses and expand operations into other countries such as Mexico/ Puerto Rico. 8 Analysis of existing network We have reviewed your existing network layout and have discovered several flaws in the design. At first glance, we have discovered your core consists of a single T1 connection providing service for all of your branch offices. Each branch office has a 64K link to the home office. The single T1 connection will be saturated after 24 branch offices link with it. Since you have well over this many branches we see a definite need to upgrade your existing infrastructure. We have also noticed that you have a single point of entry, which provides no redundancy. If a route goes down either inside or outside the network, there are no alternate paths to take. This configuration would make the entire network in accessible for both eCommerce and to each branch location. The same statement is true for each branch location as there are no redundant paths in your existing design at all. Once inside the network all of your links are 10Mbps, which causes a bottleneck to your server farm. Having the inability to provide eCommerce solutions to your clients will cause them to call your employees directly. You would be required to staff more employees, which in turn would also be required to use a system that cannot handle the workload. Thus, your existing network design is actually costing you more to operate due to losses in revenue. You will also be required 9 to staff more personnel since call volume for sales will undoubtedly be required to accommodate your customers. We have also noticed that your existing network is not segmented into separate broadcast domains. Having a single broadcast domain is yet another bottleneck in your network. The headquarters branch will have difficulty communicating even between nodes connected to the same LAN. Furthermore, you are utilizing RIP inside your network, which is vastly inadequate to deliver the performance required for business operations. RIP is a distance-vector routing protocol that relies on hop count to calculate routes. Thus, in the event a 56K link is one hop from its destination, and a 100M link consists of two hops, RIP will take the slower link (Routing Information Protocol, 2007). 10 Customer constraints     Budget Employee training Personnel Technical support Budget: We have put together a plan to release funds in phases. We have managed to keep the budget of this project under the maximum of $15M, while implementing state of the art technology. The budget section on page 16 outlines all aspects of the budget in detail. Employee Training: It is clear that we will need to upgrade some of your software. As such, your employees may need additional training to adjust to the new system. We also recognize that you have limited IT personnel. We will be contracting the hardware installation. Once installed your IT staff should be able to manage it. Personnel and technical support: Our personnel will be available for a period of 90 days after each phase to assist with employee questions and concerns. Any issues found will be diagnosed and corrected by our staff. In the event of hardware failure the appropriate hardware manufacturer will handle any warranties such as replacement hardware and such. Our staff will replace all hardware that fails under warranty free of charge for two years after implementation. We will continue to support failed hardware after two years but fees will be assessed depending on the complexity of the work involved. 11 Goals of new network design      Scalability Speed Reliability Security Manageability Scalability: We recognize investments are important business decisions, that AutoZone is a growing company, and that you would like to continue growing. As such, we have designed a network with scalability to insure your future upgrades are well in line with your budget. With our design, there will be no need to replace hardware for years to come. In the event an upgrade is required, your border routers are capable of handling six modules each, which can also provide the speed you need for many years. We have taken careful consideration when picking hardware to insure it is capable of employing future technologies such as VoIP, and IPv6. Four routers on the inside of your network can employ wireless communications for future scalability. Speed: Our existing network design will accommodate 100 T1 links at a time. Our first objective is to upgrade your existing headquarters design. Upgrading the headquarters branch first will relieve the pressure put on the network from each branch office. The new design will easily compensate for the 64K links from each branch. The complexity of your network will increase as phases progress. An OC3 link will be required for every 100 T1 links added to the network. For redundancy, we recommend installing two links at a time during the 12 upgrade phases. Your top 100 branch offices will need to be upgraded from 64K links to T1’s. Our design will compensate for a maximum of 200 T1 links. Reliability: Reliability is important when considering the industry in which your company has invested. Your headquarters branch consists of the most recognized network manufacturer in the world, Cisco. We have designed a reliable network that will allow you to query databases in real time, and redundancy to ensure both you and your customers always have access the information requested every time, all the time. Security: Security is quickly becoming a very important factor in business. Customers must be able to trust the vendors they deal with. Our security measures not only insure no outside interference, we have employed encryption techniques to make sure your customer information remains YOUR customer information. The implementation of both hardware and software firewalls is yet another measure taken to make sure intruders stay out of your network (Teare, 2004, pp. 545-602). Manageability: Your new network will have full monitoring capabilities. This will allow real time tracking and resolution of issues on your new network. In the unlikely event something occurs you will have the capability to quickly isolate the cause of network issues which in turn will allow quick resolution with minimal revenue loss. 13 Analysis of new network The new network design for AutoZone features dual 7206 routers by Cisco. These routers feature fault tolerance. The 7206 router chosen will support WAN links up to OC3 each. The new network design employs full redundancy. In the event a single link goes down a backup link will take over. Your new network will consist of dual OC3 WAN links. We recognize a monthly bill for dual OC3 links is expensive and have managed to find a way of configuring OSPF to load balance incoming branch/eCommerce links (Ng, 2007). Our implementation will conserve your bottom line by utilizing both incoming links to your headquarters office. Thus, you will not waste revenue on an untapped link. Your new network features a full mesh design. In the network CORE each device will deliver 1Gbps of bandwidth. Not only will the CORE be fast, it will deliver high availability, reliability, and stability. The core also consists of highspeed switches from Cisco, 2960. “The series offers: Integrated security, including network admission control (NAC), advanced quality of service (QoS) and resiliency, and intelligent services for the network edge.” (Cisco Catalyst 2960 series switches, 2007). For security, a Cisco PIX-535 firewall was employed to protect the edge from intruders. Finally, we have considered the use of wireless technology to assist in the mobility of employees. The Cisco 1801 routers, which are serving as 14 DISTRIBUTION routers can also serve as access points. As a security measure, these routers are capable of encrypting data using the WPA standard to keep your data secure (Ciampa, 2006. pp. 297-301). These access points are fully IEEE 802.11g/b capable to insure compatibility with existing devices (IEEE 802.11, 2007). Furthermore, every host machine we upgrade will have Symantec Norton AntiVirus installed to keep viruses out of your network. For each branch office, we will be adding the reliability of a Netgear layer three switch and a Sonicwall firewall. These two components will add security by using Access Control Lists in the switch and using one of the fastest packet scanning technology available, deep packet inspection firewall. A 6Mbps cable link will be used as a backup link at each branch location. Careful consideration was made when choosing hardware for this upgrade. All hardware chosen is fully compatible with IPv6 and is VoIP ready. In the event AutoZone decides to employ VoIP in the future, your hardware will be ready for it. 15 Implementation schedule The system upgrade is estimated to complete in 133 days. Our senior project manager will monitor the progress of the project and report it to your lead IT manager. Below we have listed the major milestones toward the completion of this project. Each date listed is an estimate as there may be unforeseen issues as the project progresses. Estimated implementation schedule for entire project Estimated date 09/03 - 09/10 09/05 - 09/07 09/10 - 10/08 10/01 - 10/15 10/11 - 10/12 10/15 - 11/05 11/05 - 11/14 11/14 - 11/16 11/19 - 12/03 12/03 - 12/12 12/17 - 12/19 12/20 - 01/10 Estimated length 6 Days 3 Days 21 Days 11 Days 2 Days 16 Days 8 Days 3 Days 11 Days 8 Days 3 Days 16 Days Job description Network analysis Collect hardware cost Replace headquarters cable Install and configure hardware Configure load balancing Testing / error correction Replace branch cable (100) Install and configure branch hardware Testing / error correction Replace branch cable (100) Install and configure hardware Testing / error correction Testing of new network Initial tests would be deployed on a pilot. We would like to minimize down time during the upgrade and a pilot will accomplish this goal. Your existing T1 link will remain while the OC3 line and one of our redundant links is configured. During the upgrade, the T1 link would remain available to minimize down time. Once the OC3 link, and mesh is configured it will be tested for connectivity, delay, and 16 security. We estimate the upgrade should be completed within 133 days of inception. The headquarters will upgrade first so that each branch office will have 99.99% availability. Once the upgrade at the headquarters office is completed each branch office will be upgraded simultaneously in lots of 100 (phase 2 and 3 respectively.) 17 Budget Total budget for the first phase is approximately $5.8M. Each subsequent phase is approximately $4.5M. The total for all three phases equals 10.3M. Below we have highlighted the budget needed for the first phase of this project. Each subsequent phase is lower in cost because your headquarters branch will require minimal upgrading. Headquarters budget Hardware Labor and design Project management Employee support Miscellaneous ATM connections Software ExtraLAN SNMP 1 user Symantec 300 user Total headquarters cost $4,000 $11,000 $1,291,000 $150,000 $600,000 $300,000 $150,000 $50.000 $26,000 Branch Budget (100 branches) Hardware Labor T1 connection Miscellaneous $220,900 $3,200,000 18 $40,000 $1,000,000 90 days of free technical assistance is Total branch cost $4,460,900 included in this budget. If assistance is required beyond the budgeted time additional fees will be assessed. It is understood that on average an OC3 line costs $13,000 monthly and a T1 costs $400 monthly (Internet access from T1 to OC48, 2007). Return on investment We have analyzed your current financial position against the cost of this project to determine how long it will take the network upgrade to return all of its investment funds. Annual Revenue Monthly Revenue (Annual Revenue / 12) Total budget cost ROI (Monthly revenue / Total budget cost) $5,948,400,000 $495,700,000 $10,212,800 49 Days This analysis does not take into consideration revenue gained by employees that are more productive, higher customer satisfaction, and revenue gained because less network maintenance is required. Furthermore, a reduction of down time would result in less lost revenue as we calculated your losses to be near $700,000 per hour. 19 Conclusion The enterprise network design proposed defines several benefits to AutoZone outlining how network technology can largely improve areas of information security, network availability, and overall network performance. Our goal at Network Design Solutions is to provide the best customer service, technical support, and professionalism as possible. Our designers have analyzed AutoZone’s current network infrastructure from the bottom-up approach to identify your needs first, and then tailor the network to meet your needs. Our design proposal will eliminate all current inadequacies by dividing the existing network into VLAN segments. Our upgrade will start with in the CORE layer, then the Distribution Layer, and finally Access layer. The project will take an estimated 133 days to be completed and will be implemented as a pilot design along-side AutoZone’s existing network to minimize downtime. Our team of highly experienced professionals are competent, and proficient in installing, managing and troubleshooting the most complex enterprise designs. We take pride in providing the best technical services and project management services to our clients. It is our pleasure to present this proposal to AutoZone. Thank you for reading our enterprise design proposal; we look forward to doing business with you for years to come. 20 Appendix NETW-410 Enterprise Network Design with Lab Customer Research and Analysis Template AutoZone INC. 123 S.
