How SDN will change Layer 4-7 network services
With SDN apps, engineers can deploy virtual appliances for Layer 4-7 network services that will be automated for more granular traffic management.
-
Understanding OF-Config and OVSDB protocols
OpenFlow directs network packet flows, but OpenFlow configuration protocols, OF-Config and OVSDB, form relationships between controllers and switches.
-
How data center network fabric and SDN intersect
SDN and data center network fabrics both enable converged networking and the ability to manage many switches as one. Where do the two intersect?
-
Software-defined networking architecture choices
Two SDN architecture models -- centralized and decentralized -- have much in common, but key differences center on the use of the OpenFlow protocol.
-
SDN technologies: Architecture revolution or evolution?
SDN can be implemented with a centralized controller or distributed architecture. In choosing SDN technologies, is a complete overhaul necessary?
-
Network functions virtualization primer
With network functions virtualization (NFV), engineers replace network devices with software on basic servers for flexibility and cost reduction.
-
SDN security: Tight policy and a new network perimeter
Software defined networking introduces network programmability and granular traffic management, which could contribute to enhanced SDN security.
-
SDN security challenges: New technology means new risk
With the promise of programmable networks will come a slew of SDN security challenges, including the need to protect the new network controller.
-
Floodlight primer: An OpenFlow controller
In software-defined networks, engineers use Floodlight controllers to manage physical and virtual devices -- and each traffic flow running between them.
-
Network-as-a-Service could be a reality with OpenFlow
Software-defined networking could solve the problems that Ethernet and IP networking pose to Network-as-a-Service by centralizing a connection permission policy.
-
Software-defined networks address cloud VLAN problems
In order to create dynamic private cloud networks, engineers will turn to software-defined networking and control planes that integrate virtual and physical switching.
-
Will software-defined networking standards be open?
If software-defined networking standards are to work, they must be truly open. But how can users and developers be sure software-centric networking standards are really open?
-
Software-defined networking and open APIs = integration
The answer to cloud networking is more than software-defined networking; it's network-centric software with open APIs that could result in deeper network systems integration.
-
Why software-defined networking is becoming a reality
Software-defined networking isn't a new concept, but it's newly able to evolve due to fast processing speeds. Will that mean a future for network application development?
-
OpenFlow: Abstract the control plane for cloud services
Cloud providers want an API for the network layer to control the flow of specific applications -- a capability we see emerging with OpenFlow and software-defined networks.
-
Where SDN and NFV intersect … and where they don't
SDN and NFV are not part and parcel to each other, but when the two sets of technology meet they advance each other's capabilities.
-
SDN and NFV in mobile networks mean orchestration
In mobile networks today, it can take months to deploy infrastructure and services, but SDN and NFV allow for orchestration and dynamic provisioning.
-
What network functions virtualization promises
Using NFV, engineers can virtualize devices and services in large networks to make their architectures cost efficient and flexible.

Parsing through the software-defined storage hype
Software-defined storage can be many technologies, but most aim for decoupled software, automated provisioning and non-proprietary systems.
