Software defined networking
Consider these 6 SD-WAN challenges and the flip-side benefits
Cost, complexity, security, training, troubleshooting and software bugs are some of the top SD-WAN challenges. Discover more about these issues and how to offset them. Continue Reading
SD-WAN (Software-defined WAN)
Software-defined WAN (SD-WAN) is technology that uses software-defined networking (SDN) concepts to distribute network traffic across a wide area network (WAN). Continue Reading
What is the difference between SDN and NFV?
SDN and NFV are siblings but not twins -- while they have a lot in common, they aren't identical. Here's what you need to know about their differences. Continue Reading

software-defined networking (SDN)
Software-defined networking (SDN) is a network architecture that aims to make data center networks agile and flexible. Continue Reading
How does SD-WAN analytics monitor network performance?
With SD-WAN analytics, administrators can fine-tune their WAN connections and determine how well their network is performing. Continue Reading
Better security through software-defined perimeter know-how
Network attacks keep changing, which means your strategy for protecting the network must too. Learn one advancement that's replacing traditional network architectures.Continue Reading
How is service mesh architecture different from SDN and NFV?
Service mesh separates itself from SDN and NFV approaches with its clear focus on managing the communication and forwarding between multiple microservices.Continue Reading
What is a programmable data plane and where does P4 fit in?
A programmable data plane presents a versatile way to forward packets and supports various formats and protocols. The P4 language is used to configure the forwarding actions.Continue Reading
How do SDN protocols compare to those used in SD-WAN?
Traditional SDN controllers use northbound and southbound APIs to communicate. But software-defined WAN controllers don't rely on those same SDN protocols.Continue Reading
What is a software-defined perimeter, and do I need it?
An evolving network world requires evolving network security. Learn how software-defined perimeter offers a compelling answer to network vulnerabilities.Continue Reading

SDN controller (software-defined networking controller)
An SDN controller is an application in a software-defined networking (SDN) architecture that manages flow control for improved network management and application performance.Continue Reading
What is the status of VNF deployments among service providers?
Although service providers are undertaking VNF deployments in the network core, they're hard-pressed to deploy them at the network edge due to complexity and cost.Continue Reading
Does software-defined networking architecture use segment routing?
Segment routing steers packets using a list of instructions, and it can be used in MPLS and IPv6 architecture. But does software-defined networking architecture support it?Continue Reading
Does software-defined networking architecture need network overlays?
Network overlays and software-defined networking architecture share a history. But while overlays offer flexibility, they also bring extra overhead and troubleshooting complications.Continue Reading
Software-based networks lay foundation of networking's future
Software-based networks are evolving, reshaping how companies do business and blending into legacy networking. Enterprises will have to sort out which approaches work best.Continue Reading
