The big picture of a network is that it is defined by the little details. Which IP address is supposed to be used where (Resources)? Which Element is connected to what (Topology)? Which role does this particular element have (Element configuration)? What characteristics does a provisioned service have (Services)?
The power of BECS is the way it intelligently joins up the four key dimensions necessary for effective automation: Resource Management, Service Configuration, Topologies and Element Configuration. By knowing the answer to these questions and how they are related, true end-to-end automation is accomplished.
Another essence of the network is that it has an evolutionary characteristic that is often overlooked. BECS is designed to help you across the full life-cycle of your network.
During a build-out, many new elements need to be configured in a short period of time. They need to comply with your defined policy for the network. What does the IP plan look like? How should the elements be connected? Which configuration, based on the specific role of the element, should be activated? Which software version should be used? These are all fairly simple questions to answer by themselves, but mistakes easily happen, especially if volumes are large.
With BECS these answers are defined in a network policy and enforced automatically. When BECS connects to elements, it will upgrade or downgrade the software and apply the configuration according to your network policy. It will warn about errors in the topology, so you can quickly react and rectify the problem. You will no longer apply the wrong Access List, configure a duplicate IP address or run the wrong software version in your production network.
In short, automation is key to minimize errors and maximize efficiency.
