The Open System Interconnection (OSI) protocol suite is comprised of numerous standard protocols that are based on the OSI reference model. These protocols are part of an international program to develop data-networking protocols and other standards that facilitate multi-vendor equipment interoperability. The OSI program grew out of a need for international networking standards and is designed to facilitate communication between hardware and software systems despite differences in underlying architectures.
The OSI specifications were conceived and implemented by two international standards organizations: the International Organization for Standardization (ISO) and the International Telecommunication Union-Telecommunications Standards Sector (ITU-T).
Optical Transport Networks are widely deployed. Originally used to provide high-capacity links between major network nodes or few end users with large bandwidth capacity, optical is now flooding metropolitan and residential networks. The Optical Transport Networks become more and more a mass market. The management of such equipment relies on OSI protocols for the communincation between NMS (network management system) and NEs (Network Elements).
The Legacy SONET/SDH equipment or NMS Platform are so largely deployed that telecom manufacturers still require support, upgrade or evolution of a complete OSI solution.
MARBEN OSI product line – MARBEN OSIAM - is the leading networking solution available in portable source form. It provides the ultimate off-the-shelf management network solutions.
Marben has worked on OSI from its first year of standardisation in 1985. Marben has the largest spectrum of customers on OSI for telecommunication from SUN and HP to Adtran, Alcatel Lucent, Fujitsu, NEC, Tellabs, 600 000 stack has been deployed worldwide for SONET/SDH management.
Marben has also sold its OSIAM stack products to large industrials such as BAE, Suez in the requirement of OSI for automation.
