  • Method and apparatus for managing a communications network by storing management information about two or more configuration states of the network
    Patent number: 6308174
    Abstract: A method of managing a communications network is described which makes use of information about the current state of the network and in addition, information about past and/or future states of the network. Information about the current state of the network is stored in a management information base (MIB) and the information about the past/future states is either stored in this MIB, or separate past/future MIBs are created. The information about the past/future states is stored in a way such that it can be operated on in the same way as the information about the current state of the network. By storing the information in this way management of the network is improved. For example, future states of the network can be tested before being implemented. Also, information about past states can be used to predict future states. Fault management, configuration management, accounting management and performance management can all be improved by using the information about past/future states.
