Why SDN Is UsedTo Slice up the Network forMore Flexible ConfigurationsDynamically SegregateTopologically-EquivalentNetworks Across a Data CenterScale the Network Beyond theTypical Limits of VLANs(approx. 4,000 today)BenefitsMaximize Utilization of DataCenter Resources: 20-30%Better UseFaster Turnaround Times whenCreating Segregated Networks –Automated APIs Can Be Used toCreate New Networks in MinutesVersus WeeksData Center – Slice Up the Network in Virtualizedand/or Multi-Tenant Environments8Copyright 2013.
