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.
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 ...
Network architecture is the design of a computer network. ... The Open Systems Interconnection model (OSI model) defines and codifies the concept of layered network ...
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.

OpenFlow allows direct access to and manipulation of the forwarding plane of network devices such as switches and routers, both physical and virtual (hypervisor-based). It is the absence of an open interface to the forwarding plane that has led to the characterization of today's networking devices as monolithic, closed, and mainframe-like.
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 .
It uses an open source business model aimed at promoting networking through software-defined networking (SDN) and standardizing the OpenFlow protocol and related technologies. [2] The standards-setting and SDN-promotion group was formed out of recognition that cloud computing will blur the distinctions between computers and networks. [ 3 ]
