network design 2.pptx
This document outlines the contents of a network design and analysis course. The course covers topics such as network processes, hierarchy and diversity, the importance of network analysis, and a systems methodology. It discusses defining problems, developing options, and selecting solutions. The document also covers service descriptions, including characteristics, levels, and metrics. The overall goal is to view the network and its environment as a system to support connectivity and services for users.

- 16. A SYSTEMS METHODOLOGY •Systems methodology means viewing the network that you are architecting and designing, along with a subset of its environment. • The fundamental concepts of the systems methodology is that network architectures and designs take into account the services that each network will provide and support.

- 24. SERVICE DESCRIPTION • Networkservices are defined as levels of performance and function in the network. There are two perspectives: • As services being offered by the network to the rest of the system. • As sets of requirements from the network that are expected by the users, applications, or devices.

- 27. Service Characteristics • Servicecharacteristics are individual network performance and functional parameters that are used to describe services. • Characteristics of services that are requested from the network can also be considered requirements for that network.

- 43. Performance Characteristics • Capacity,is used as a label for the class of characteristics that involves moving information from place to place, including bandwidth, throughput, and so forth. • Delay, is a label for the class of characteristics that includes end-to-end delay, round-trip delay, and delay variation. • RMA, is a label for the class of characteristics that includes reliability, maintainability, and availability.

- 47. Network Supportability Two majortasks must be accomplished to ensure supportability: 1. Conformance to the network architecture and design must be validated and nonconformance corrected or documented to ensure that performance is adequate and that maintenance can be performed. 2. Operations and maintenance personnel must understand and be trained in the technologies that are being deployed.
Editor's Notes
- #4 Network analysis, architecture, and design are part of the engineering process that form the basis of networking projects. Such projects have immediate, tactical (near- term), and strategic (long-term) significance, and networking projects should consider all of these areas. These plans are intended to be iterative and should be regularly reviewed.
