Adara's data plane is built on top of a dynamic multipath routing and switching overlay. It provides capabilities such as dynamic QoS, TCP acceleration, and data de-duplication as virtualized network functions. Adara Sirius Routers provide dynamic routing based on available bandwidth and real-time latency. To meet the SLAs of the customer applications, it's very important for the data plane to provide this level of agility. As customers' operational or financial SLAs change, Adara's control plane elements (such as SLA Manager or Orchestration Engine) interact with the data plane elements to make the changes in the switched or routed paths. To minimize bandwidth costs, de-duplication-based compression functions are also used on demand.
Adara SLA Manager provides an interface for administrators to specify the true cost of an infrastructure resource at a granular level. For instance, it lets the administrator specify the cost per bit on a physical interface based on an ISP's SLA (time of day, bandwidth cap, and bursts allowed) and the cost per CPU based on the cloud service provider's SLA. Using the cost settings and monitored infrastructure parameters, Adara SLA manager renders the OPEX Dashboard for the business users to visualize how and where their money is spent and allow them to fine tune it.
Adara provides an orchestration GUI for cloud customers to input their expected infrastructure requirements: predicted number of users, expected response time, priorities of their hosted services, and the daily and/or monthly budget. Adara OE starts with an optimal configuration for the specified requirements. It fine-tunes the infrastructure setup automatically to provide best performance without exceeding the specified budget. OE continually learns and optimizes the configuration based on manual and automated training.
Adara SDI Visualizer provides a topological rendering of the hosted services, virtual machines, and underlying network infrastructure. This dynamic GUI enables the cloud administrator to monitor and reconfigure service and VM policies.
These are only few examples of the building blocks that constitute a True SDI. SDN vendors should come forward to provide much more innovative and practical tools for customers instead of fighting among themselves in standards wars. Focusing on providing interoperable solutions is critical to allowing early adopters to appreciate the value of SDI.
