Title : Software Defined Networking Performance and Architecture Evaluation Presenters : Brian Chong Audience : Cloud/Network Architects that are using a Overlay Model to create their Virtualized Network Fabrics Objective : This presentation will cover architectural and performance characteristics of what a Overlay network is compared to a straight VLAN based environment on a cluster size of 100+ nodes. Over the last 3 months, Symantec has run extensive performance and diagnostics tests across multiple overlay providers as well as against the base Neutron VLAN configurations and have come to several insights into CPU penalities, Network design issues at scale as well as performance comparisons using different encapslation techniques. We will explain what our architectural design was, the results of our testing as well as our design insights into how Symantec’s cloud will be affected by the outcome of the evaluation.
