Cisco last fall promised to support OpenFlow on its Nexus data center switches but found in the ensuing months that OpenFlow has less appeal in the data center and more in academia and research, company officials said.
Other components of Cisco ONE include its Nexus 1000V virtual switch, which the company says can be used as the basis of virtual overlay networks for multi-tenant cloud deployments. Nexus 1000V now supports OpenStack Quantum and REST APIs for multi-tenant orchestration, open source hypervisors and a VXLAN gateway connecting physical VLAN and virtual networks.
VXLAN is a network encapsulation technique with segment identifiers for creating millions of logical networks and for enabling workloads to move across data centers and cloud infrastructures. The networking segments will support multitenant cloud infrastructures that require segmentation for security and compliance, Cisco says.
The Nexus 1000V will also now support policy-based, per-tenant virtual security services on VXLAN-based overlay networks.
Cisco ONE is designed to support a variety of deployment model for programmability, including network partitioning, or 'slicing,' in universities and research using OpenFlow agents and controllers; network flow management for massively scalable data centers; automated provisioning and programmable overlay networks for the multi-tenancy requirements of cloud providers; programmatic policy and analytics for service providers; and private cloud automation for virtual workloads in enterprises, including desktop virtualization.
Beta trials and phased general availability are scheduled to begin the fourth quarter of 2012.
