ISR 4000s have the capability to “license” throughput.
the solution was built this way with clear goal in mind. previously it was hard to estimate how given router will perform under some random set of features. the CPU driven routers by themselves have a lot of challenges to address, so measuring performance and then sticking to it with each and every new software release was simply unrealistic. we published “kpps” numbers, but then got heat from our Customers, when performance was lower with each and every enabled service....
while observing how people tend to behave in so called “serious situations” and “serious environment” I began to create different theories. as i’m lacking background in psychology i was not proficient in doing that, but then I stumbled upon this article. in particular, this quote caught my eye:
For poor performers to recognize their ineptitude would require them to possess the very expertise they lack.
indeed, that’s the case! and it’s worth remembering as well, that:...
…because of that, for example.
contrary to ‘beliefs’ and dogmas, that until being ridiculed are broadcasted widely, only the scientific method works. actually works. it allows us to continously attempt to verify by experiment our theories, build theorems and laws - and realistically predict and describe behavior of the universe around us.
i highly recommend using it.
quite recently Piotr Jabłoński, one of the best architects and consultants in Polish Cisco Systems office presented session very similar to this post topic during our CCIE club meeting. independently, this topic is often brought back on CCIE.pl forum, and Mirek Burnejko asked for couple of comments with regards to growth of whitebox networking.
so… does rise of SDN really mean end of the world for CCIE?
yes and no....
a year ago, the idea was to test the wide range of different IPv6 implementations and solutions. this year, we’re gathering together to turn on IPv6 - in the devices, on the portals - and let it be on forever. the idea is World IPv6 launch - worth reading about and obviously joining yourself. cisco is part of the initiative and again the first vendor to join it.
