The huge demand for network resources is straining overall network systems, resulting in the poor performance of networks. This could lead to latency, overload and network breakdown. Rapid advancements in software defined network (SDN) technologies could help in solving the above said issues by bridging the gap between physical and virtual components to create a highly flexible networking environment.
New analysis from Frost & Sullivan's (technicalinsights.frost.com) Breathtaking Innovations in Software Defined Networking research finds the shift to next-generation load balancers, network security, and software defined firewalls are the major focus areas in the development of SDN. Successfully overcoming security challenges inherent in software components will also help SDN adoption.

Symmetric-based SDN is popular since it enables tighter control over the virtual network. This is crucial as organizations ranging from large-scale corporations to small businesses rely on analytics to establish their business models and require better control over the data flowing through their networks.
"SDN is considered best suited for data centers as conventional networks that depend on different tiers of Ethernet switches are unable to satisfy the computing, storage and flexibility needs of huge storage data centers," said Frost & Sullivan Technical Insights Research Analyst Sathya Vendhan. "Comprehensive, integrated SDN solutions are more competent than a completely physical approach, since they enhance system performance and reduce costs."
The most important driver for SDN adoption is cost effectiveness. It allows customers to use their network assets with greater efficiency and fully utilize existing infrastructure through advanced virtualization capabilities.
In several cases, however, incompatibility with existing infrastructure curbs SDN deployment. Accountability concerns, the dominance of physical components, and the use of questionable software components add to the challenge. While SDN empowers users to build their own appliances, such as firewalls over the network, it also provides hackers with extra points of entry, making the underlying hardware more prone to malicious attacks.
"The potential of SDN can be realized only when research organizations form consortiums and consolidate knowledge to develop various aspects of this nascent technology," advised Vendhan. "For now, SDN urgently requires a strong set of standards and protocols that can guide its evolution, which is possible only through strategic relationships, partnerships and joint ventures among organizations, vendors and developers."
