Legacy applicationsmight still exist that must be supported going forward, and these applicationsmight require a legacy protocol that may limit a design. Network Design Step 1: Determining Technical Constraints Similar to business constraints, technical constraints represent any of a number of technical issues and obstacles that will impact the network design. These constraints can have a significant effect on network design and must be taken into account. From the Book.
Top-Down Network Design, 2nd Edition $75.00 This chapter serves as an introduction to the rest of the book by describing top-down network design. Below are the most familiar design constraints that must be addressed by a network designer. The constraints of network design are existing factors that cannot be altered, often impacting architecture and functional requirements. The network designer would be given a list of business and technical goals, along with a blank check.

This chapter covers typical network design business goals and constraints and talks about the top-down process for gathering information on goals, and the importance of using systematic methods for network design. The role of each is discussed, and the pros and cons of various approaches are described. Backbone network design, as well as distribution, regional network design, and access design—In these three sections, you will examine the details of designing core, distribution, and access networks. Technical constraints include existing cablingthat does not support new technology, low bandwidth might not support new applications. Network design might be affected with different technical constraints. Network Design Step 1: Identifying Business Constraints In a perfect world, a network design project would not have any business constraints.
