Virtual Devices by Michael Morris
Just a quick link to our reader to check out Michael Morris’s write-up on Virtual Device Contexts. Michael, nice blog, detailed, and very well thought out. Michael’s blog.
I wanted to point out that this is another example of ‘organic innovation’ brought forth by Cisco Engineers and Product Managers working intimately with our cutting edge customers. The genesis of this idea by the way came from a variety of sources, but one was Mike van Norman from UCLA’s networking group who wanted to share a large switch with four departments and optimize his infrastructure without proliferating a lot of smaller devices. Mike, wanted you to know we never forgot, and we delivered. Even though that lunch was in a deli in LA in 2003/2004 I think.
Also, for anyone who wants to copy this innovation (not that I encourage blatantly copying others pioneering efforts): have fun rewriting your entire operating system architecture to be modular, multi-threaded, with separate memory-state machines for each stateful process. Should take 3-4 years if you start today…
