Software Defined Network (SDN) are designed using a network architecture model that separates the control plane from the data plane of network equipment (routers, switches, etc.). Once separated from the data plane, the control plane can be exported to a single, centralized control point, the SDN controller, which controls and manages all network equipment in a cohesive manner.
This separation allows for the control plane to be deployed on servers whose capacity is greater than traditional network switches, while adding a level of abstraction from network equipment features. The abstraction, which is achieved through an API (Application Programming Interface), enables the development of high added-value network services (load balancing, configuration automation, planning, intelligent routing, etc.) without any manufacturers’ constraints (vendor lock-in). Thus, these programmable, centralized networks can easily and quickly adapt to a company’s changing needs.
Today’s network infrastructure is made up of several physical components (oftentimes, proprietary). In addition, the infrastructure is based on hardware that can quickly reach the end of its useful life, requiring a new design, integration and deployment. This phenomena is compounded by the rising cost of energy, capital investment issues and lack of skilled personnel to design, integrate and operate increasingly complex network technologies. What’s worse is that the life cycle of hardware keeps getting shorter as services and technological innovations increase in the IT and communications fields.
The concept behind NFV (Network Functions Virtualization) aims at solving these problems through the use of virtualization technology, which is used in IT, to combine several network functions on servers, switches and storage systems deployed in data centers, network nodes or with subscribers.
The NFV concept is used with SDNs. Although these two concepts are mutually beneficial, they are independent from each other.
NFV offers many benefits, including:
• Lower equipment costs and energy consumption, by consolidating equipment and taking advantage of the IT industry’s economies of scale
• Faster commissioning times, by reducing the network operator’s typical innovation cycle
• Use of a single platform for several functions, applications and users
• Services can quickly be adjusted according to needs
• Existence of many ecosystems and freedom from vendor lock-in constraints
An SD-WAN (Software-Defined Wide Area Network) is an application that is specific to the SDN concept, applied to a company’s WAN communications links. An SD-WAN manages several WAN communications links at once, as well as multiple private virtual networks established between the different physical locations serviced.
An SD-WAN is made up of physical or virtual equipment installed in each one of a company’s locations and managed by a controller (SDN) installed either in one of the locations or on the Cloud. For example, an SD-WAN can be used to link many branches to a centralized corporate network, data centres or Cloud-based applications. The SD-WAN provides dynamic, seamless WAN links that help lower costs and maximize network performance, while improving ease of management.
A private fiber optic network is a telecommunications infrastructure that links a company’s buildings within a specific perimeter. This type of infrastructure is a very valuable asset, in that it provides independence with regard to data transmission speeds. And, operating costs are fixed and will not vary with transmission speeds, as is the case for traditional telecommunications links.
The largest private fiber optic networks in Quebec were planned and designed by Groupe Conseil Génicom. We offer a wide array of consulting services aimed at designing, deploying, maintaining and managing this type of network. So, break free from service providers and lower your operating costs by owning your own fiber optic network!
