IT and Network

Modern-day networks deliver more than connectivity. Organizations are embarking on transforming themselves digitally. Their networks are critical to this transformation and to their success. The types of network architectures that are evolving to meet these needs are as follows:

Software-defined (SDN): In response to new requirements in the “digital” age, network architecture is becoming more programmable, automated, and open. In software-defined networks, the routing of traffic is controlled centrally through software-based mechanisms. This helps the network to react quickly to changing conditions.

Intent-based: Building on SDN principles, intent-based networking (IBN) not only introduces agility but also sets up a network to achieve desired objectives by automating operations extensively, analyzing its performance, pinpointing problematic areas, providing all-around security, and integrating with business processes.

Virtualized: The underlying physical network infrastructure can be partitioned logically, to create multiple “overlay” networks. Each of these logical networks can be tuned to meet specific security, quality-of-service (QoS), and other requirements.

Controller-based: Network controllers are crucial to scaling and securing networks. Controllers automate networking functions by translating business intent to device configurations, and they monitor devices continuously to help ensure performance and security. Controllers simplify operations and help organizations respond to changing business requirements.

Multidomain integrations: Larger enterprises may construct separate networks, also called networking domains, for their offices, WANs, and data centers. These networks communicate with one another through their controllers. Such cross-network, or multidomain, integrations generally involve exchanging relevant operating parameters to help ensure that desired business outcomes that span network domains are achieved.
