Disclosed is a method and system for keeping correlation system up-to-date with latest relationship information across multiple devices. The method and system intercepts a stream of data to determine changes to the system. Thus as one or more services are created or destroyed as per server virtualization, the correlation system is updated.

A Method and System for Real-time Discovery System

Correlation systems are systems that build a set of relationships between devices. The set of relationships facilitates an operator to associate a fault with a particular device or connection between devices.

With the recent server virtualizations, where thousands of resources can be created and destroyed in short span of time, it has become a challenge to keep the correlation systems up to date with the changes that happens with creation/removal of resources/devices in the network.

There are existing methods/systems that are used to assist the correlation systems in staying up to date, some kick off a discovery on receipt of a particular message type (cold start or warm start traps for instance), others on receipt of a configuration change message. All the systems are helped by this but still hobbled as they rely on their own discovery engine to query devices for configurations and connections.

In accordance with the method and system disclosed herein, streams of data originating from service creation, provisioning and activation systems are parsed for determining changes (creation and destruction of one or more services) in the network. Accordingly, the correlation systems are updated with latest relationship information across devices.

Changes to an enterprise can be done in a number of ways, some of those ways are kicked off by service catalogs, some are done by provisioning and activation systems. Similarly, changes are made by calls to element management systems from orchestration systems followed by messages from element management systems to devices. On the same lines, changes can also be made by commands typed on the devices themselves. Accordingly, the system can receive actual messages or it can receive log files echoed from device or service catalog configurations.

Following figure illustrates a block diagram of the system for parsing stream of data for updating correlation systems.

As, the stream of data (service and resource configurations) is intercepted by the system, line by line configuration commands (as they executed on a device) can be directed to the system. For systems like service catalogs that do not send out a message about a service just created to the resource that the service is created on, transaction log files are directed to the system disclosed here.

The system includes a class...
