2020 Global Networking Trends Report Summary

Core Content

This report outlines the evolving landscape of networking in the context of the digital age, emphasizing the need for a new kind of network that can adapt to the demands of modern business and technology trends. It highlights how traditional networking approaches are no longer sufficient due to the increasing complexity, scale, and dynamic nature of current IT environments. The focus is on the integration of advanced technologies like AI, automation, and intent-based networking to improve network performance, security, and operational efficiency.

Main Trends and Key Points

Global Business and Technology Trends

Globalization 4.0: Digital goods and services, powered by AI, are becoming the main exports, driving a more interconnected and digital world.
Digital Business Transformation: 88% of executives believe digital disruption will have a major impact on their industries, compared to 27% in 2015.
Business Automation: Automation and robotics are expected to lead to significant cost savings (up to $471 billion by 2022) across multiple industries.
Business and Operational Resilience: Organizations are becoming more dependent on complex technologies, requiring proactive risk assessment and incident response.
Sustainability: Networks are expected to play a key role in reducing energy consumption, emissions, and waste through greater efficiencies.

Technology Trends Driving Network Evolution

The Evolving Application Landscape: Applications are becoming modular, distributed, and increasingly consumed from SaaS providers. By 2021, over 50% of workloads will be outside the enterprise data center.
IoT Growth: By 2022, there will be over 14.6 billion IoT devices globally, with M2M devices accounting for 51% of them.
AI and Machine Learning: AI is enabling smarter, more adaptive networks. It is being used for real-time decision-making, policy enforcement, and automation. AI processing may range from the cloud to the edge.
Mobility: Mobile data traffic is growing sixfold from 2017 to 2022 at a 42% annual rate. Employees expect secure, high-performance connectivity from any device, anywhere.
Security Challenges: Cybersecurity threats are becoming more sophisticated, and traditional perimeter-based security is no longer sufficient. Networks need to provide visibility and protection across distributed environments.

The Need for a New Kind of Network

The current scale and complexity of networks are exceeding the capacity of human operators alone.
A new network must be agile, secure, and integrated across all domains (campus, branch, WAN, data center, cloud, etc.).
The new network should be able to comprehend business and application requirements, translate them into policies, and automate operations to ensure continuous delivery and protection of services.

Emerging Network Architecture

Cisco experts envision a controller-based network model that integrates automation, AI, and policy enforcement.
Intent-based networking (IBN) is seen as a critical component of this new architecture, allowing networks to translate business intent into policy and ensure service performance and security.
Software-defined networking (SDN) and network automation at scale are foundational to this transformation.
Open-platform IBN controllers will enable integration with adjacent services, other IT domains, and heterogeneous infrastructure.

Network Operations and Talent

Network operations are becoming more integrated with business intent, automated, and data-driven.
The future of network operations includes policy management, assurance management, and predictive analytics.
Network talent is evolving. IT leaders must prepare for new skill sets that combine technical and business acumen, as well as soft skills.
Crossover roles and network strategists will become more prominent, with a focus on delivering value beyond connectivity.

Key Predictions

By 2025, leading-edge networking teams will have intent-based networks operating across all domains. These networks will be autonomous, intelligent, and able to continuously adapt to changing business needs.
The network will provide end-to-end bandwidth, low-latency communications, and dynamic performance controls to support immersive experiences like VR and AR.
Network automation will significantly reduce complexity and improve agility, with a shift from reactive to preventive problem management.

Recommendations for IT Leaders

Assess network readiness to ensure it aligns with business needs.
Build a roadmap for implementing intent-based networking across all domains in incremental steps.
Invest in talent development by identifying and prioritizing IT processes and applications that will benefit most from open-platform network controllers.
Integrate AI, ML, and MR into network operations to improve policy enforcement, threat detection, and automated decision-making.

Conclusion

The digital era demands a new network architecture that is intelligent, automated, and aligned with business intent. With the rise of IoT, AI, and mobility, the network must evolve to support distributed applications, secure connectivity, and operational resilience. IT leaders must prepare for this shift by investing in technology, adapting operations, and developing new talent strategies. The future of networking lies in intent-based models that enable agility, efficiency, and continuous improvement.
