Hybrid OpenFlow Switch
In This Chapter
Alcatel-Lucent supports Hybrid OpenFlow Switch (H-OFS) functionality. The hybrid model
allows operators to deploy Software Defined Network (SDN) traffic steering using
OpenFlow (OF) atop of the existing routing/switching infrastructure.

Hybrid OpenFlow Switching
The hybrid OpenFlow model allows operators to deploy Software Defined Network (SDN)
traffic steering using OpenFlow atop of the existing routing/switching infrastructure. Some
of the main benefits of the hybrid model include:
• Increased flexibility and speed for new service deployment—H-OFS implements
flexible, policy-driven, standard-based Hybrid OpenFlow Switch traffic steering that
allows deployment of new services and on-demand services through policy updates
rather than service and infrastructure programming.
• Evolutionary capex/opex-optimized SDN deployment—The H-OFS functionality
can be deployed on the existing hardware through software upgrade, realizing
benefits of FlexPath programmability. The OpenFlow traffic placement is focused
access only (i.e. flexible, fast, on-demand service deployment) while network
infrastructure provides robustness, resiliency, scale and security.
In a basic mode of operation, a single OpenFlow Switch instance is configured on the router
and controlled by a single OpenFlow controller.
