Here are some important factors for network architects to consider before adopting an SDN solution from my colleague, Joe Marsalla. Joe is Ciena’s CTO for the EMEA region.
Software-defined networking (SDN) is one of the most interesting developments in network architecture to emerge in over a decade. Enticed by the opportunity for a more simplified infrastructure and the ability to provide a new level of flexibility, operational efficiency and faster reconfiguration of network resources, service providers and enterprises alike are optimistic about its future.
A recent IDC report predicts the worldwide SDN market for the enterprise and cloud service provider segments could grow from $960 million to more than $8 billion by 2018. This growth is being fueled by organizations looking to realize critical CAPEX and OPEX reductions, and to enable greater agility for the delivery of new services across their common infrastructure. This fundamental shift in networking architecture is radically changing the networking industry landscape and has become too important for network operators to ignore.
While SDN has evolved and matured significantly in recent years, and is ready for implementation today, a careful examination of objectives and technology requirements will ensure that rollouts deliver the maximum return for the end customer and ultimately the business. Here are some important factors for network architects to consider before adopting an SDN solution:
SDN has indeed brought a lot of promise to the networking industry. The ability to both simplify networking equipment, and even virtualize it, while at the same time improving network programmability and control means SDN holds the promise of a more efficient world in terms of CAPEX and OPEX and enabling new revenue streams. But, it’s also important that we are doing it for the right reasons, implementing SDN correctly and not simply recreating the same closed environments that exist today. If we can do this, we can truly unlock SDN’s potential.
