With the introduction of multicloud, digitization of the workplace, IoT, and upcoming transition to 5G, network service providers, cloud providers, and enterprise organizations are at a critical turn in their evolutionary path. Keeping pace with increasing demands of their customers and employees, whether it is for increased bandwidth, new services, or better, application-based quality of experience, will require their networks to be more flexible and agile than they are today.
Network operators are facing some fierce new challenges with the emergence of IoT and 5G, along with the migration of data, applications and other business elements to the cloud. While these trends are vital to push the envelope in their respective fields, they are challenging service providers to deliver increased bandwidth and application quality of service. Serving increasingly stringent requirements along with mounting scale increases the complexity of networks. Organizations everywhere are looking for solutions to simplify such complexity within their networks — which is where Segment Routing (SR) comes to the rescue.
We’re living in the era of software-defined. The new(ish) style of network management is permeating IT infrastructures everywhere and is commonly being applied to wide area networks (WAN), giving us SD-WAN. SD-WAN marks a shift in the way networks are deployed and managed, as it supplies existing wide area networks with many new capabilities for the automated and rapid deployment of equipment and services while enhancing application performance with better economics. SD-WAN creates this dynamic application experience by simplifying the management and operation of a WAN through the separation of the networking hardware from its control mechanism. Given the AI-driven visibility, analytics and automation associated with SD-WAN, networks underneath this design tend to be secure, reliable and scalable.
In the world of networking, SD-branch follows SD-WAN’s footsteps, with the two abiding by a similar template. Both are policy-based, automated approaches to IT infrastructure at the branch, designed to achieve agility via SDN. Essentially, SD-branch solutions evolve the SD-WAN technology that is widespread among today’s enterprise WAN, simply extending the ease-of-management and security features to what’s happening inside branch offices beyond the WAN edge, including the wired and wireless network and any branch-local services on a universal CPE platform.
The networking industry is perpetually evolving. It has to. With new applications and innovations affecting networks every day, architectures must adapt to keep pace with today’s digital demands. In fact, these demands inspire innovations within the networking industry itself — such as the implementation of software-defined networking (SDN).
Timing is everything, especially when it comes to making important business decisions in the face of new challenges. One such challenge for service providers these days is latency — a small but mighty side effect of millions of devices simultaneously overloading a network, therefore sucking up bandwidth and impacting efficiency for higher revenue services.
