SID (shared information/data) as the information model: The different mod- ules that make up the NMS and the communication between applications and NMS need to use a common format of data and information for interop- erability. SID is currently the most popular information and data model for use in telecom management. The same is adopted for the generic framework development. With SID, first the object in the management framework needs to be identified. This is followed by identification of object attributes and relationship with other objects. Advantages of using SID in NGNM framework: Information in standard format leads to reuse of data. More applications that can work on a specific format. Published standards of data leads to independent and open source devel- opment of product. More competition leading to more challenging services that work on the data. C. Interface model with OSS/J and extended support for MTOSI (multi- technology operations system interface): OSS/J has been adopted for defin- ing the interface language. This is because Java is now extensively used in Report: NGNM Framework and Adoption Strategy developing telecom network management modules and most of these com- ponents support OSS/J for interface. The queries that are supported with OSS/J are mostly generic and some of the commands on inventory and fault management including certain specific activations cannot be performed with generic OSS/J. This leads to support MTOSI for some specific level queries. If the applications that interact with the NMS have support for MTOSI then there would definitely be a scope to add specialized NMS functions. This can be achieved with an MTOSI adapter. Advantages of using interface standardization with OSS/J with MTOSI adapter in NGNM framework: Standards in interface lead to reuse of application. More applications that can request and respond on a specific format. Published standards for interface leads to independent
