promotes innovation Applications are independent of infrastructure Distributed architecture reliable scales under unpredictable growth 01 14 19 Separation of forwarding path and control plane Push services out to the edge Globally meaningful addresses in each packet empowers each node to make decisions PACKET DESIGN INC SLIDE 16 Change is Required The Internet must evolve to accommodate New applications New types of devices and users New types of content New level of scale in multiple dimensions Amount and type of traffic Number of users Driven by optics ubiquity and services 01 14 19 PACKET DESIGN INC SLIDE 17 However We must evolve the architecture without losing its key attributes Open Application independent Distributed Technologies such as ATM and MPLS have many of the scaling limitations of strings Routing needs to evolve beyond the 1960 s algorithms in use today 01 14 19 PACKET DESIGN INC SLIDE 18 Architectural Vacuum Initial Internet was funded by DARPA government this is no longer true Due to time to market pressures most network vendors are not investing in architecting these services for the long term Instead we see point product or band aid solutions optimized for single environments first ATM now MPLS which will not scale as required for the Internet 01 14 19 PACKET DESIGN INC SLIDE 19 Internet Impact Internet Everything Critical infrastructure for
