Today many look to SDN as the next big revolution in Networking. But why is there such hype? What radical change in the economics of networking will shift the industry? The answer is Virtualization.
Virtualization’s growth is still in its infancy, and many aspects remain unexplored. Still there are aspects of which we are certain:
- With an explosion in the number of Virtual devices, it is unaffordable for humans to remain in the loop for routine network operations.
- Emerging business models are not achievable when (slow) humans are involved in the provisioning process. Read More »

This post is about the onePK software architecture, and how it allows us to consistently expose network operating system (NOS) features to a wide variety of programming environments for IOS, IOS-XE, IOS-XR and NXOS.
For an overview of onePK in general, and some more context, see my October 2012 post and my slides in Slideshare.
The main elements of the onePK software architecture are illustrated Read More »

Enterprise trends driving SDN and Network Programmability are becoming clearer. The skyrocketing number of virtual/cloud devices is making human configuration infeasible. A natural result will be that networks will move from being integrated based on physical box boundaries to being integrated based on software boundaries. Put another way, traditional box based network integration will be overwhelmed by device proliferation. Therefore businesses must adopt new approaches to device configuration and control. This will include a new layer of network software which will instantiate, orchestrate, and dismantle virtual networks.
But what does this really mean? Read More »

This is the first in a series of posts about network based software development for “typical” enterprise developers, and how onePK can help.
Network based software development is special. The main interfaces are based on CLI interactions and SNMP, not to mention using RADIUS as a RPC mechanism, various forms of XML/HTTP found nowhere else, and additional innovations. For a typical enterprise or script developer these kinds of interfaces are unusual, to say the least. Read More »

Part of the interest in programmatic interfaces is fueled by the desire to logically centralize network control functions. A global view of network state can have many benefits but it does not preclude the use of distributed protocols within the network. Network Programming Interfaces (NPIs) provide a facility to construct global state, mutate that state and distribute that state to the network which in combination with distributed protocols can aid in achieving greater network efficiencies, improve visibility, robustness and add to the value of the network overall. When used the right way, these NPIs will help set a new balance between centralized and distributed control. Key to this balance will be domain or deployment specific constraints. Read More »
