Core networks

Core networks are the key tool for delivering IT services in any company and are the heart of the IT system. They transfer information from servers or applications to the user, as well as between IT systems themselves.

A key point for delivering IT services

Core networks provide connectivity and routing between different parts of the network and control the flow of data traffic between them. With the rise of digital transformation, the most significant shift is happening at the level of system integration that leads solutions such as big data and Internet of Things, which mean that IT systems are now having added devices and sensors that haven’t been used in IP networks until now.

Did you know that 80% of all network traffic is generated within the data center without ever leaving it?

Because of this, a core network today would be inconceivable without high-speed broadband (10 Gb or more) connections. The core network is the most critical part of a company’s IT system and should be designed to be very fast, reliable, scalable and secure, which means it should be planned carefully and tailored to the company’s processes regardless of the company size.

Key principles of core networks

Core networks should be streamlined, and a quality solution should strive to be as perfectly symmetrical as possible. When it comes to more complex networks, management can be simplified with SDN technology, which provides automation, visibility and control of the core network.


Core networks must be redundant at all levels, and the failure of any component should not affect system operation.


Every core network needs to be planned so it can be expanded at any time. If a core network’s capacity is too low, you may face the need for a potentially expensive upgrade relatively quickly down the road.

The core network needs to be planned to ensure basic operational security. You must primarily focus on correct network segmentation to support effective deployment of security features into the network.
