	Description:		Simple two man show this week with Ethan & Greg talking through, oh, I don’t know ….. stuff like this What best path means in SD-WAN. Traditional best path thinking is effective, insofar as it goes. It scales to a large number of devices and destinations. It is resilient. It is mature. However, it has its limitations. Routing protocols compute best path for a given destination, not a given application. Best path computations are not influenced by real-time events such as lossy links or link congestion. In general, lower bandwidth links are not used to carry traffic (i.e. are not computed as the best path and are therefore unused), EIGRP s variance feature being a notable exception. Software defined WAN brings a much more sophisticated metric to the computation of best path. Best path is computed on a per-application basis, not per-destination. The best path for a bulk traffic application might be different from the best path for a voice application, even if heading to the same destination. Real-time link capabilities can be factored into the decision. Any link, no matter the available bandwidth compared to other links, can be used in an active/active manner. Example: IP Telephony Subnets – But the real MAGIC is in the application recognition / selection routing by subnets is simplest possible classification path selection by application is most complex possible classification will we move Where have all the good staff gone? What tends to remain behind is the residue the least talented and effective IT engineers. They tend to be grateful they have a job and make fewer demands on management; even if they find the workplace unpleasant, they are the least likely to be able to find a job elsewhere. The Wetware Crisis: the Dead Sea effect : Bruce F. Webster Who Needs to Worry About Scale ? How many devices make a large scale network ? Can you define it ? Is it one hundred switches in a data centre ? What about one hundred ( or thousand) routers in a WAN ? A Corporate Perimeter DMZ that has just 10 devices that are complex to operate and preform deeply complex operations on traffic flows ? What about 1 terabit of bandwidth ? Is it a million concurrent connections or 10000 connections per second ? What about using MPLS to build an overlay network which uses many complex protocols ? Industry thoughts in 30 seconds. Q. What can enterprises do to ensure that their infrastructure is ready for next-gen networking technology implementations emerging in the next decade? Q. What networking protocols do you see as growing in importance in 2015? Q. What role will cloud and virtualization play in the enterprise data center in the next few years? 1:07 another break Response: My Industry Thoughts in 30 Seconds – EtherealMind Datanauts Show 001 – Hyper Convergence with Scott D. Lowe Why SDN in The Enterprise Data Centre Will Take Decades Enterprise Data centres are static and change occurs on decade long cycles. SDN creates disruptive change to budgets, technical operations, and highlights the failure of existing task frameworks based on ITIL & PRINCE2 Over-investment in existing assets prevents incremental adoption creating more obstacles to adoption.
