RE: INE OER free class!

In general network hardware consists of two portions, the Control Plane and the Data Plane. The Control Plane is where the software runs to determine how the network should work, e.g. OSPF, IS-IS, BGP, MPLS, etc. The actual forwarding of traffic between interfaces is done in the Data Plane. The ASICs live in the Data Plane and have very simple operations, like encapsulating and decapsulating Ethernet Frames. They do not "run IOS". IOS or JunOS or whatever network OS is used on the platforms runs, in the most part, in the Control Plane. On each physical router/switch in your standard network, each device runs an independent copy/process of this network OS. This is what OpenFlow is trying to solve.

With OpenFlow the network devices basically become like dumb terminals. The Control Plane of the network is centralized to some sort of cluster of machines, and then instructs the physical boxes in the topology how traffic should be processed in their Data Plane.

What companies like Google are doing is buying hardware (mainly 10Gb Ethernet right now) that can be programmed in software through features like OpenFlow. Like I said companies like this already have the top-most level software engineers in the entire world working for them. It's not an issue of whether or not they know how to program logic gates on an ASIC. They set out to accomplish a goal that no one has thought of before, because they are by definition innovators.

"Pretty much all the manufacturing for all the ASICs and low level stuff is already in China, Taiwan, etc. What the article is saying is that companies like Google are just buying the chips direct from the manufacturer and then running their own software on them, effectively bypassing the need for Cisco IOS or Juniper JunOS."

So if they rean't buying ASIC's then what are they buying?
Can you clarify Chips?
If they are buying ASIC's so then they are writing their own version of IOS code to those ASIC's?

Ciso has patent im sure of the IOS code, so if these companies are writing their own code? Again, how do you support?

John
