Hottest SDN Tech Of 2018
Software is front and center in the networking world this year as customers demand more programmable, agile and less costly network solutions.
The increasing adoption of cloud-based services and need to reduce data center complexity is driving sales for technologies such as software-defined WAN and intent-based networking. The global software-defined networking solutions and services market is projected to increase 54 percent on a compound annual growth rate (CAGR) over the next several years, reaching $88 billion by 2024, according to a research report by Global Market Insights.
CRN breaks down ten of the coolest and most sought-after software-defined networking technologies in the market so far in 2018.

Cisco Intent-Based Networking
Cisco has been investing heavily in its one-year-old intent-based networking platform in 2018 which now boasts 5,800 customers. CEO Chuck Robbins recently told CRN that Cisco’s intent-based strategy — which uses software to automate network policy and management — is shifting more toward an open, software-defined architecture. The San Jose, Calif.-based networking giant is making DNA Center, the control and management plane for intent-based networking, an open platform to allow partners to develop custom applications and offer more SDN solutions for customers. Cisco also launched two new software systems, Network Assurance Engine and DNA Center Assurance, in 2018 to boost the platform’s SDN capabilities.
