In telecommunications, and in the context of Federal Communications Commission's (FCC) Computer Inquiry III, Open network architecture (ONA) is the overall design of a communication carrier's basic network facilities and services to permit all users of the basic network to interconnect to specific basic network functions and interfaces on an unbundled, equal-access basis.
The ONOS (Open Network Operating System) project is an open source community hosted by The Linux Foundation.The goal of the project is to create a software-defined networking (SDN) operating system for communications service providers that is designed for scalability, high performance and high availability.
Systems design is a process of defining and engineering the architecture, methods, and interfaces necessary to accomplish a goal or fulfill a set of requirements. In open systems architecture, the design includes intentional provisions to make it possible to expand or modify the system at a later stage after initial operation.
The Open Systems Interconnection (OSI) model is a reference model from the International Organization for Standardization (ISO) that "provides a common basis for the coordination of standards development for the purpose of systems interconnection."
The Open Systems Interconnection model (OSI model) defines and codifies the concept of layered network architecture. Abstraction layers are used to subdivide a communications system further into smaller manageable parts. A layer is a collection of similar functions that provide services to the layer above it and receives services from the layer ...
Basically, the open-system environment model is a basic building block of several technical reference models and technical architecture. A technical architecture identifies and describes the types of applications, platforms, and external entities; their interfaces; and their services; as well as the context within which the entities interoperate.
Open architecture is a type of computer architecture or software architecture intended to make adding, upgrading, and swapping components with other computers easy. [1] For example, the IBM PC , [ 2 ] Amiga 2000 [ 3 ] and Apple IIe have an open architecture supporting plug-in cards, whereas the Apple IIc computer has a closed architecture .
An open-access network (OAN) refers to a horizontally layered network architecture in telecommunications, and the business model that separates the physical access to the network from the delivery of services. In an OAN, the owner or manager of the network does not supply services for the network; these services must be supplied by separate ...
