Significant BSD descendants
By integrating sockets with the Unix operating system’s file descriptors
, it became almost as easy to read and write data across a network
as it was to access a disk. The AT&T laboratory eventually released their own STREAMS
library, which incorporated much of the same functionality in a software stack with a different architecture, but the wide distribution of the existing sockets library reduced the impact of the new API
. Early versions of BSD were used to form Sun Microsystems
, founding the first wave of popular Unix workstations.
Standard sets of information models
The Distributed Management Task Force
(DMTF) provides a standard set of information models for various enterprise domains under the general title of the Common Information Model
(CIM). Specific information models are derived from CIM for particular management domains.
The TeleManagement Forum
(TMF) has defined an advanced model for the Telecommunication domain (the Shared Information/Data model
, or SID) as another. This includes views from the business, service and resource domains within the Telecommunication industry. The TMF has established a set of principles that an OSS
integration should adopt, along with a set of models that provide standardized approaches.
The models interact with the information model (the Shared Information/Data Model
, or SID), via a process model
(the Business Process Framework (eTOM)
, or eTOM) and a life cycle model.
