Autonomic Networking – From Theory to Practice

Autonomic Networking is well understood in theory, but real, consistent and extensible implementations don’t exist. In this post I suggest a reason for the lack in execution, and our vision to provide a working, implementable Autonomic Networking Architecture.

Wipe off the dust…

When asking a researcher about autonomic systems, (s)he might blow the dust off a stack of papers, or proudly pull a couple of old books off his shelf. Or point to IBM’s IEEE paper from 2003. From a research perspective, autonomics is well understood. It’s this self-management thing, with all those self-* properties. Self-configuration and self-optimisation for example. Distribution, control loops, and so on. Even the Wikipedia articles are written. So, we’re done, aren’t we?

No we’re not.

Ask your friendly neighbourhood network engineers about Autonomic Networking. The one that proudly hacks expect scripts at night to make his admin database talk to his routers. Or the front line engineer who applies a network service class to one of his customers. Likely, both of them would look at you with big eyes, and after explaining that the network manages itself, intelligently, you’d hear back: “That’s like Skynet, isn’t it?”

No it’s not. Read More »

DO NOT PANIC: Autonomic Networking is on the Horizon!

dontpanic

By looking at the sheer amount of Breakouts and technical sessions here at Cisco Live London, it isn’t hard to understand why networks are becoming more and more complex.  Networks are converging onto single infrastructures, more and more business processes are becoming more network centric and this translates into more functionality and more dependencies between functions and network layers, and thus more complexity.  It becomes very hard for a single human being to understand these dependencies and layer interactions in order to do per-box configuration.  Typically this problem is attempted to be ‘solved’ by moving some of these dependencies and layer interactions into a central place, but that just moves the problem.  Wouldn’t it be cool to allow networks to become self-aware, such that they can learn from their neighboring nodes ?
