Networks are increasingly becoming complex and distributed. As a result, problems like hardware failures, performance degradation, resource allocation, bandwidth monitoring and assignment and service provisioning are harder to solve and become real challenges for Network Operation Centers (NOC). The NOC is in constant search for efficient integrated network management systems required to monitor, interpret, and control the behavior and performance of the network, its hardware devices and software resources.
This article discusses the three network management architectures in use today, so by reading it you will be able to understand the differences between each architecture, and by reading the pros and cons of each architecture you will be able to select the right solution, especially when managing a distributed network.
The three network management architectures are:
