In telecommunications, Multi-Technology Operations System Interface (MTOSI) is a standard for implementing interfaces between OSSs. Service providers (carriers) use multiple Operational Support Systems (OSS) to manage complex networks. Since the various parts of the network must interact, so must the OSSs. It is standardized by the Telemanagement ForuM (TM Forum). The TMF Frameworx provides a set of reference models that aid in analyzing and designing next generation BSS and OSS solutions that may utilize the MTOSI interface specifications.
A visual representation of the TMF MTOSI offered SOA Service Candidates is shown in the figure.
The MTOSI specifications are produced by the TM Forum MToP program.
MTOSI standard is a unified open interface that can be used among multiple types of management systems to provide network and service management. MTOSI standard covers all communication technologies (from layer 1, e.g., SONET/SDH, through higher layer technologies such as VoIP).
MTOSI facilitates application-to-application inter-working, reduces time to deployment, and lowers the cost of ownership of systems.
Current management and support system implementations employ diverse middleware technologies, a reality that is not likely to change in the immediate future. To be widely adopted, MTOSI cannot mandate specific middleware technologies for its implementation. Therefore, the MTOSI interfaces are sufficiently abstract to be middleware neutral, yet rigorous enough that vendors can map them quickly to their middleware of choice. The CCV is the common middleware required to implement MTOSI.
CCV is a middleware abstraction that allows MTOSI interfaces to be bound to different middleware technologies as needed. By exploiting the expressive power of Web Services Description Language, MTOSI interfaces are composed of logical and physical definitions.
