Netronome Agilio-CX Demo – Ericsson Cloud SDN With OpenDaylight Accelerated Agilio-CX Intelligent Server Adapters for Improved Telco NFV Performance & Flexibility
An important requirement for Telco NFV Applications is high performance data-plane scaling and throughput, while maintaining data plane flexibility for rapid feature innovation. While software based Open vSwitch forwarding provides good flexibility, the low forwarding rate of the software-based data plane makes it difficult to implement many NFV applications with a reasonable amount of server resources. This is because NFV applications are very data intensive, so the amount of server resources needed to implement the virtual switch function to feed these hungry applications can in many cases consume the majority of server CPU resources. In addition, software based virtual switches often become a bottleneck, thereby starving NFV applications and limiting performance.
To address these problems, many operators are looking at offloading and accelerating the software virtual switch data plane layer to free up the server CPU resources, while at the same time increasing the forwarding rate to hungry NFV applications. This approach has a dramatic effect on operator total cost of ownership, because a given amount of NFV processing can be done with much less server resources, in many cases up to 80% less. At the same time, it is important that any acceleration and offload techniques that are used do not come at the expense of networking capabilities and connectivity flexibility.
The Netronome Agilio-CX demo demonstrates how an open approach using the OpenDaylight Controller and Open vSwitch with Ericsson Cloud SDN and Netronome Agilio-CX can seamlessly deliver high performance and server efficiency while maintaining flexibility, thus resulting in real business benefit for Telecom Operators. High performance packet throughput is achieved by accelerating the Open vSwitch data plane on the Netronome Flow Processor on the Agilio-CX Intelligent Server Adapter thus removing the Open vSwitch bottleneck. At the same time, up to 90% of the server CPU cores are freed up from running OVS and become available to run more NFV applications. And importantly, the transparent offload approach that is used on Agilio-CX, coupled with the use of open software, means that maximum feature flexibility and innovation is maintained.
