Break Scalability Barriers in OpenFlow SDN

16

Over the past couple of years, software-defined networking (SDN) has emerged as a strong alternative to traditional networking approaches in the areas of WAN, data center networks, and network overlay solutions. The primary benefit realized from SDN, besides open networking, is the ability to accelerate service deployments. SDN solutions using OpenFlow tackle complex problems, including dynamic provisioning, interconnection, and fault management. Although the functionality of SDN has evolved and matured, the scalability of SDNs based on OpenFlow has been limited by OpenFlow’s ties to ternary content-addressable memory (TCAM). OpenFlow by design was implemented in the TCAM.
