OVO-1.9 is a component of the Teko framework that helps applications to communicate with multiple different protocols and services. It provides a low level, protocol-agnostic, service-oriented architecture that unifies the communication of various individual applications and services from the standpoint of the application itself. OVO-1.9 enables applications to expose its own services, register new ones, and consume services from other applications. It is made up of several components, such as the OVO Router, the OVO Service Directory, and the OVO Storage.
