MORE: Critical milestones in Cisco history LEADERSHIP IN SDNs? Cisco tries to head off software-defined networks Cisco has also promised to add OpenFlow to its Nexus data center switches . And start-up/Cisco spin-in Insieme Networks is developing what many believe is the next generation of Cisco'sNexus switching line, with programmability hooks. "Insieme fits into our strategy; it does not define it," said DavidWard, chief architect and CTO of Cisco's Service Provider division. Cisco's multipronged SDN strategy was reiterated by Kiran and Wardduring the conference call. The officials stressed that SDNs willaugment current network and Internet functionality -- not replaceit - and that customers will adopt various flavors of SDNs based ontheir particular needs or requirements. "I'm not sure there is a killer application for SDNs that can't beachieved in architectures today," said Kiran "Its promise issimplification." Enterprises could use it to virtualize workloads and implementvirtual desktop environments, and orchestrate security profiles for private cloud automation, Ward said. He then outlinedthe Cisco OPEN architecture, the same one previewed by CTO Padmasree Warrior in her Interop keynote earlier this month. Cisco OPEN, which is also expected to be officially introduced atCiscoLive, is intended to open up the network with APIs at layersother than just the data and control plane, which is where thepopular OpenFlow protocol is targeted. Cisco's SDN architectureharvests network intelligence from the infrastructure, delivers itto an analytics engine which then churns it into orchestrationroutines for policies, which are then programmed back into thenetwork infrastructure. Cisco says this architecture will apply to all flavors of SDNs -from direct APIs between applications and the network; to controllers governing OpenFlow-enabled devicesand other agents; to virtual overlays between applications and thephysical and virtual network. In this scenario, OpenFlow is but one of many protocols and APIsthat can be used to implement SDNs, Cisco officials stressed. Andinstead of commoditizing its hardware, as many in the industryexpect, Cisco says SDNs will create more value for Cisco's ASICs,operating systems, software-based services and partnerapplications.
