The '''Open Systems Interconnection protocols''' are a family of information exchange standards developed jointly by the [[International Organization for Standardization|ISO]] and the [[ITU-T]]. The standardization process began in 1977.

The goal of an open-standard protocol suite instead has been met by the [[Internet protocol suite]], maintained by the [[Internet Engineering Task Force]] (IETF).
