Today’s Networks are Defined by the

“Box”•Hardware, Operating System, and

Applications Built Into a “Box”.

•Cannot Mix and Match

•Mainframe Mentality

•Lack of Competition at Each Layer

•Barrier to Entry

Challenges

•Rapid Innovation in Computing Technology

•Massively Diverse User Groups

•Demand for Bandwidth Growing Rapidly

•Increasing Costs - CAPEX & OPEX

•Increasing Complexity - 5400 RFCs
