The Term Open Network Refers To A Specific Type Of Network That Consists Of Open Standards And Hardware Equipment.

In other words, the open network guarantees the openness of a computer system in terms of the compatibility of hardware and software components and the ability to expand and expand. Additionally, available networks are a general term that refers to open standards.

Network administrators can make the best use of the potential capacities of an open network system . So that their hands are available in choosing the hardware and software that shape the network, they have a greater level of choice, and they don’t have to rely on a vendor to provide the required products.

An open network’s main advantages include the potential for cost savings compared to proprietary vendor products and achieving a higher level of network redundancy.

Open networking allows organizations to add applications or tools directly to existing hardware. For example, organizations can use routers, switches, firewalls, or load balancers that meet their needs to implement a stable and robust network.

Open networks are similar to open standards, which focus on creating standards for interoperability and data exchange around public consensus processes. An available network is the opposite of a closed network, where the equipment required to implement the web is limited to a few specific providers.

How should we implement the open network?

There is no clear definition in this field, and the network’s level of openness depends on the network expert’s experience and technical knowledge. For example, open networking can refer to extensive networks that provide the highest network interoperability and dependency on a specific component.

On the other hand, open networking may have more limited functionality and is based on a software-oriented networking (SDN) approach implemented through open-source protocols. It should be clarified that open networking may refer to pairing an open-source networking operating system with virtual hardware in a virtual machine.

Interestingly, the open network concept also has different meanings for sellers. A vendor may define open networking as a way to conform to existing networking standards or use a set of open-source APIs that work with other tools. In addition, the above term for some vendors may refer to a certain level of network openness. which is consistent with the standards they emphasize.

What are the characteristics of an open network?

An open network product usually has various features, the most important of which are the following:

• Open APIs
• open industry standards related to hardware and software;
• open source components, such as network devices and computing hardware;
• An open ecosystem that can work with other types of tools and hardware.
• Cloud processing.

SDN in the available network

The SDN is also a common aspect of open networks. SDN is an architecture that aims to make networks more agile and flexible to improve network control. Then SDN enables network administrators to view traffic from a centralized control console. The SDN architecture includes an application layer, a control layer, and an infrastructure layer. SDN enables enterprises and service providers to respond quickly and adapt to changing business needs.

Open networking leverages the principles of SDN while adding the use of open-source platforms and defined standards. SDN networks also usually use open APIs. Operators can manage the entire network and devices with a single control layer, even if the underlying network is complex.

SDN works well with open networking because it enables multi-vendor interoperability and supports a multi-vendor approach. Open APIs help many applications, while publicly available software manages hardware from vendors that use empty application-based products.

Open Networks Foundation

The Open Network Foundation (ONF) is a non-profit organization that promotes the implementation of open networks. ONF develops software-defined standards for available networks. ONF divides its means into the following categories:

• Technical specifications: includes framework documents, protocol definitions, information models, and component interoperability capabilities.
• Technical recommendations: related to APIs, protocols, and models that define the process of sending and receiving data.
• Information: includes case studies, applications, and reports on the tests performed.
• In addition, ONF works on projects related to broadband, mobile, cloud edge, and SDN to create open-source tools and standards.

Examples of open networks

Organizations can use an open-source controller operating system to manage low-cost hardware in a computer network.

In September 2019, Comcast and ONF launched an open-source software called Trellis. Trellis is an architectural pattern that develops network functions with virtualization-based and SDN NFV-based fabrics for network services. Trellis works with an open-source SDN controller and an OpenFlow protocol that acts as an API.

The OpenFlow protocol lets servers inform the network of the switching process and where packets should be sent. The ONF defines the OpenFlow protocol as a standard communication interface between SDN-based architectures’ control and dispatch layers.

In conventional networks, each switch has software that tells the controller what to do. By comparison, packet forwarding decisions in OpenFlow are centralized, meaning that the web can be programmed independently of switches and data center equipment.
