Abstract: A system comprising a network of network elements and a data store associated with a data store manager. The data store contains data representing the actual state of the system and data representing a planned state of the system. The data store manager causes the network elements, or processes supported thereby, to conform with the planned system state. In addition, at least some of the processes communicate to the data store manager data representing their respective state. The data store manager, upon receipt of said data, updates the actual state data in accordance with the received data. The data store provides an actual model and a planned model of the system by which the state of the system can readily be managed.

Abstract: A proxy agent for communicating data components between a Network Management System (NMS) which supports a first network management protocol, for example Simple Network Management Protocol (SNMP), and one or more network elements which support a second protocol, for example Transaction Language 1 (TL1). The proxy agent comprises a directory for storing the data components wherein each data component is associated with a first data component identifier which is compatible with the first protocol, and with a second data component identifier which is compatible with the second protocol. The directory provides an inherent mapping between protocols and obviates the need for a separate mapping component. The directory may conveniently comprise a Lightweight Directory Access Protocol (LDAP) directory.
