Preparing networks, and people, for times of trouble

1.Preparing a company for disaster, above all, involves planning, both in terms of technological redundancy and staffing.

2.When looking at a diagram of a company's network infrastructure and wide area network links, one should be able to put a finger over any device on the chart -- as if it were down -- and know that the network can keep running.

3. While most large providers, such as UUNet, have their own backbones, other second-tier providers may use a large provider's backbone. That means that, even though a company may have two service providers, its data is traveling on one path.

4.Route optimization : This method judges traffic conditions on the network and helps to ensure that data takes the quickest route given the current conditions on the Internet.

5. Plan : Wanted to ensure that its IT operations could continue even if all of its personnel were unable to access its buildings.
