Continuing the theme of physical design, this chapter focuses on the aspect of Active Directory Network Services infrastructure and the considerations relating to physical components. As the previous chapter discussed topics relating to the physical design and placement of the Active Directory Services infrastructure, this chapter focuses more on the practical aspects of networking in support of Active Directory services.
The foundation of networking in any organization is the network topology, which includes routers, switches, network protocols, intranets, extranets, and connectivity to the Internet. If the underlying network is poorly designed or not able to scale to meet business demands, then any infrastructure layered on top will more quickly highlight these limitations and shortcomings.
This chapter begins with a discussion of some of the best practices for designing a network topology, including routing, router placement, Internet connectivity, addressing and subnetting, and firewall considerations. These components all have a bearing on the infrastructure used on top of them and therefore require careful consideration when deploying an infrastructure.
Throughout the book we discussed the...
