Rather than relying on point products, enterprises should let the network become a security sensor and enforcer, Cisco says.
In this article, I will do a walk-through of a logical network diagram. As I also said in the Physical Diagram article: I prefer to use the term “logical” instead of “L3″ because it is more easily understood by somebody unfamiliar with the OSI model. It also removes the assumption (made by many non-technical people) […]

Who knows what SDN stands for?
APIC – Application Policy Infrastructure Controller
UCI – User Centric Infrastructure
APIC-EM – APIC Enterprise Module
Eventually, APIC and APIC-EM will have a common policy model so they can share policies across DC and enterprise. They will not integrate directly but will talk to a common policy orchestrator.
APIC-EM is really focussed on brownfield deployments because the assumption is that customers already have networks up and running hat APIC-EM needs to integrate into. APIC-EM won’t cconfigure OSPF and STP today, things like that, because they’re more than likely already running.

If you’ve watched any of the recent Wireless Field Day presentations, you know that free wireless is a big hot button issue. The delegates believe that wireless is something akin to a public utility that should be available without reservation. But can it every really be free?
Let’s take a look at other “free” offerings you get in restaurants. If you eat at popular Mexican restaurants, you often get free tortilla chips and salsa, often called a “setup”. A large number of bars will have bowls of salty snacks waiting for patrons to enjoy between beers or other drinks. These appetizers are free so wireless should be free as well, right?
The funny thing about those “free” appetizers is that they aren’t really free. They serve as a means to an end. The salty snacks on the bar are there to make you thirsty and cause you to order more drinks to quench that thirst. The cost of offering those snacks is balanced by the amount of extra alcohol you consume. The “free” chips and salsa at the restaurant serve as much to control food costs as they do to whet your appetite. By offering cheap food Continue reading
