A gateway between client manager applications and an enterprise manager may be provided to manage various networked objects. In one embodiment, CORBA-based TMN manager applications may be communicatively coupled to a CORBA Object Request Broker (ORB) and may be operable to send Interface Definition Language (IDL) requests to, and receive IDL responses and CORBA events from, managed objects through the CORBA ORB. The client manager may first be authenticated to the gateway by username and password, or other validation information associated with the client manager, which may be represented in a user profile. Once the initial client authentication is accomplished, the gateway may provide object-level access control between manager applications and managed objects at an individual object level so that one of the managers is granted access to one of the managed objects while being prevented from interfacing with a different one of the managed objects.

Secure access to managed network objects using a configurable platform-independent gateway providing individual object-level access control

A CORBA Gateway between CORBA-based applications and an enterprise manager may be configurable to manage various networked objects, such as printers, scanners, copiers, telephone systems, etc., which may be interconnected via networks. CORBA-based manager applications may communicate managed object-related messages, such as events, requests, and responses, with the managed objects through a CORBA Object Request Broker (ORB). The CORBA gateway may translate the manager requests from IDL to PMI requests. Similarly, the CORBA gateway may translate the enterprise manager PMI responses and PMI events to IDL/IIOP responses and events which may be passed on through the CORBA ORB to the manager applications in the form of IDL responses and CORBA events. In some embodiments, the client may choose the format in which to send and receive message information. To provide text based events, requests, and replies, an extension IDL interface may be used.

IDL event and request formatting for corba gateway

A method for processing events generated by software and hardware entities installed on a computer network that avoids overload conditions at large event processing rates is provided. In one embodiment, the method includes the steps of providing a protocol translation facility that is configured to translate messages from a first network communications protocol to a second network communications protocol. The protocol translation facility is further configured to receive events transmitted by software and hardware entities on the network. The protocol translation facility forwards the events to a management information server. An event is received, and a determination is made whether an association between the protocol translation facility and the entity exists. The event is processed
