Continuing the theme of physical design, this chapter fouses on the aspect of Active Directory Network Services infrasructure 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 shotcomings.
This chapter begins with a discussion of some of the best practices for designing a net work 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 infrastucture.
Throughout the book we discussed the topology and behavior of a network within the perimeter of...
