The Network and Services Integration Forum (NSIF)
In order to assist in the SONET standards process, the Network and Services Integration Forum (NSIF) was formed to provide an open industry forum for the discussion and resolution of multiple technology integration and SONET interoperability issues.4 Its goal is to enable the delivery of services across a set of networks from different vendors and different network operators. NSIF coordinates with the appropriate standards groups, such as ANSI and the ITU-T, as required by a specific issue.
NSIF is a nonprofit membership organization comprised of equipment vendors, service providers, and other industry players who cooperatively develop end-to-end multitechnology service delivery capabilities based on industry and international standards.
