In recent years network downtime has become even more costly with the convergance of voice and data technologies and the ever-increasing reliance placed on network services. With this in mind it is important to understand your current network environment and plan for future requirements.
Taking On Support
One of the first things we do is build a complete picture of the existing physical network so you can determine how well your existing infrastructure supports your business. Going through this process helps us to identify any needs for upgrades to the existing LAN or WAN. We with a simple representation of the entire network to identify locations of offices and the connections between them, and then build in more detail, as illustrated by the following figure:
To obtain a detailed picture of the LAN and WAN configuration, we create a diagram of all site locations, connection types, and network topologies (such as bus, token ring, or star). Include the locations of firewalls and perimeter networks. Your assessment should also include a thorough inventory of the hardware that currently makes up your network infrastructure, including stand-alone and clustered servers, routers, and switches. Also note all data center logistics, including rack space, cabling, and power supplies. "Checklist for Evaluating a Network Environment" lists specific items we examine during this assessment.
In general, you should assess your network infrastructure from the following perspectives:
- Geographical considerations
- Bandwidth and latency
- Current usage
- Current messaging system
These areas are discussed in the following sections.
