Software Defined Networks Essential for the Cloud
By Ed Silverstein
Software Defined Networks (SDN) and Network Functions Virtualization (NFV) stand to be influential factors which could significantly change network architecture.
Though still evolving, SDN is poised to provide many benefits and is predicted to be very lucrative. One recent estimate predicts the SDN market will reach $3 billion by 2016, according to Mike Banic (News - Alert), vice president of networking at Hewlett-Packard. In addition, SDN apps will reach $670 million in three years, HP adds.
In response, HP has launched 10 new routers to support the OpenFlow SDN standard. It also is offering an SDN App Store and an SDN developer kit.
Especially in the case of cloud computing, SDN provides some major benefits with its more flexible and efficient management of network traffic, according to a recent report from ZDNet.
“SDN is an essential element in the path to the cloud,” adds a Sonus company blog post by Mohan Palat (News - Alert). “As solutions migrate to the cloud, SDN capability will allow enterprises and service providers to maximize the power of their cloud deployments.”
It is important, too, to consider how to review the SDN capability, Palat said. He explains that is relevant for both service providers and enterprises. It is especially important when choosing security and interworking solutions. That way they can maximize their return on investment and make sure a solution is “cloud-ready,” Palat said.
Another relevant topic is the relationship between SDN and Session Border Controllers (SBCs). Palat said that an “SDN enabled” SBC, provides CAPEX and OPEX (News - Alert) savings, improved performance, programmability, scalability and simpler deployment.
Looking ahead, Dennis Brouwer, president of The Brouwer Group, recently predicted in an article posted by LightReading that SDN, “has the potential to be a huge step towards a much more responsive and relevant future for core systems.”
In addition, when reaching the “promise” of SDN or NFV new systems will be offered “that are designed to give equal weight to extensibility (via common languages, tools and documentation), and interaction with other business systems (via standard APIs and service strategy),” Brouwer predicts.
