Diagram 2, Download pdf files (see Instructor) 2.1.1 - The Lifecycle of a Network 2 Diagrams Diagram 1, textual Selecting buttons displays the text below: The Prepare Phase: During the Prepare phase of the lifecycle, organizations create a business case for the network upgrade. This includes how the network can support the goals of the organization, as well as the financial justification for adding new technologies and services. The Prepare Phase can establish a financial justification for network strategy by assessing the business case for the proposed architecture. The Plan Phase: The Plan Phase involves identifying initial network requirements based on goals, facilities, user needs, and other factors. This phase involves characterizing sites and assessing any existing networks. It also includes performing a gap analysis to determine whether the existing system infrastructure, sites, and operational environment are able to support the proposed system. A project plan is useful to help manage the tasks, responsibilities, critical milestones, and resources required to implement changes to the network. The project plan should align with the scope, cost, and resource parameters established in the original business requirements. The Design Phase: The initial requirements that were derived in the Plan Phase drive the activities of the network design specialists. The network design specification is a comprehensive, detailed design that meets current business and technical requirements. It incorporates specifications to support scalability, availability, security, and manageability. The design specification is the basis for the implementation activities. The Implement Phase: After the design has been approved, implementation (and verification) begins. The network is built, or additional components are incorporated, according to the design specifications. The goal is to integrate devices without disrupting the existing network or creating points of vulnerability. The Operate Phase: Operation is the final test of the appropriateness of the design. The Operate Phase involves maintaining network health through day-to-day operations, including maintaining high availability and reducing expenses. The fault detection, correction, and performance monitoring that occur in daily operations provide initial data for the Optimize Phase. The Optimize Phase: The Optimize Phase involves proactive management of the network. The goal of proactive management is to identify and resolve issues before they affect the organization. In the PPDIOO process, the Optimize Phase may prompt a recommendation for network redesign. Redesign may be necessary if too many network problems or errors arise, if performance does not meet expectations, or if new applications are identified to support organizational and technical requirements.

Summary 1 Diagram, summary buttons Slide 1, image Cisco Lifecycle Services is a six-phase approach to deploying and operating Cisco technologies. The six phases of the network lifecycle are: Prepare Plan Design Implement Operate Optimize In the Prepare phase, the business goals of the project are identified and a business case is created to justify the installation of the network upgrade. During the Plan phase, the network designer performs a comprehensive site and operations assessment of the current network. A project plan is created that includes the tasks, timelines, risks, responsibilites and the resources required to complete the network design project. Slide 2, Image In the Design phase, the designer creates a flexible design that can integrate new technologies into the current operations and existing network infrastructure. During the Implement phase, the network is built according to the approved design specifications and tested to ensure it meets the business goals and requirements. The Operate and Optimize phases of the network lifecycle are ongoing and represent the day-to-day operations of the network. Optimizing a network is a continuous process that identifies and resolves potential weaknesses before they become problems for network operations. Slide 3, Image Includes sample RFP from earlier section Requests for Proposal (RFP) and Requests for Quotations (RFQ) solicit proposals from networking contractors to provide design services, equipment, installation and support. RFPs and RFQs provide information as to a company's business goals, requirements for new technologies and outline the process to follow to submit a proposal. Following the required format and schedule is critical to submitting a successful proposal to provide network services. A team of individuals from the networking contractor respond to the customer's request. This team includes an account manager, pre-sales system engineers, network designers and post-sales field engineers. Slide 4, Image Account managers serve as the primary point of contact between their customers and the networking contractor. Pre-sales system engineers are responsible for assisting the account manager to determine the need for upgrades or additions to the current network. They assist the network designers to ensure that the new equipment and services can integrate into the existing network. Network designers provide customers with a network design that meets the customer requirements for scalability, availability, security and manageability. Post-sales field engineers are responsible for the smooth installation of the network upgrade and ensure that the network functions as designed. All members of the networking contractor staff must demonstrate effective interpersonal skills in order to instill confidence in their abilities to provide the necessary network services. Slide 5, Image Factors that limit the ability of the business to incorporate new technology include the amount of the budget, policies, schedules and the availability of qualified personnel. Constraints can and do affect the network design and need to be considered early in the design process. Top-down network design strategies have the best chance to succeed because the designers take into account the business goals of the customer before selecting technology solutions. Bottom-up design strategies start with the selection of equipment and technologies, and then determine how to incorporate them into the network. A primary technical requirement for any network is the availability of qualified support personnel. To simplify ongoing network operations, network monitoring and management software should be part of network design. 2.6.2 - Critical Thinking 1Diagram, Activity Scenario: The XYZ insurance company has 350 agent offices around the United States. Each agent office has a Frame Relay link to corporate headquarters. Because of corporate policy, the bandwidth of the agent links is determined by and paid for by the agents working in the offices. The agents use the network connection primarily to access various database systems at headquarters and also for e-mail and Internet access. XYZ has budgeted $5 million to upgrade their outdated network infrastructure at headquarters to a fully redundant Gigabit and Fast Ethernet LAN. The management believes the upgrade will reduce long-term network costs and improve the scalability, availability, security and manageability of the LAN infrastructure. The company is starting a recruiting effort that it hopes will result in the addition of 200 new agent offices in the next three years. The company needs higher capacity to meet the potential demand of the new agents. The project must be completed in three months because of the anticipated demands of a new E-Commerce system, which will increase revenue, and a new customer service system, which will improve customer satisfaction. The existing LAN equipment is from a non-Cisco vendor although the WAN infrastructure is a complete Cisco solution. The company wants the LAN to be a complete Cisco solution as well, in part because they hope to save costs of operating the LAN with a single vendor solution. The company outsources its IT staff. The Cisco WAN is managed remotely. The IT staff that work on-site have limited training in Cisco networking. The company's web site is also outsourced. Even though the management is outsourced, the servers are located at headquarters and connect directly to the LAN because of XYZ company's policy is that all company data must be physically stored in company facilities. The insurance database systems use Oracle on Unix servers with custom-developed client software. The e-mail system is based on Eudora email client software. Qusetions (4) 1: Which two business goals of XYZ Insurance apply to this network design project? (choose 2) increased customer satisfaction from the new customer service equipment vendor increased performance from Gigabit Ethernet increased scalability of database reduced costs from managing the LAN 2: Which two items are business constraints imposed by the XYZ insurance company on this new network design project? (Choose two.) a high-performance LAN existing non-Cisco LAN outsourced IT the Eudora e-mail system $5 million budget 3: Which two are technical requirements of XYZ Insurance with regard to this network design project? (Choose two.) increased usage of the Oracle increased availability and performance of the new network a simplified, manageable network increased profitability due to reduced costs increased customer satisfaction 4: Which constraint imposed by XYZ Insurance on this network design project affects the ability of the design to meet the technical requirements reliability of the Eudora e-mail system 5 million budget experience of IT staff three months completion date transition from outdated infrastructure to gigabit Ethernet
