Or …. Is there any hope my Performance will be seen over the network? Bob Riddle, Internet2 28 March 2003 Network Connectivity

Network geeks & Performance Events What do network geeks know about dance, music, and good theater? In my case, not much … So why is a network geek involved? To answer the following questions: Can I “stretch” the stage? Do I live in the right “neighborhood” ? Is there any hope this stuff will work when I need it to work?

Stretching the “Stage” Speed: do you need a freeway, city street, or a dirt road? Latency: is it a “telephone” call or a “movie”? Packet Loss: is there any “junk mail” you can throw away? Things to think about when “stretching” the stage

Stretching the “Stage” -cont- Determine the quality of the Experience Mpeg1~= 1.5 mpbs H.323~=384 kbps Mpeg2~=7 – 16 mbps DV~=30 mbps Determine the type of Experience One way?(streaming, broadcast) Two way?(interactive voice, video) Many way?(more than 2 end points) Do the math!

You have to live in the Right Neighborhood Take a look at your local neighborhood 1.Run internal tests across you LAN 2.Make sure you’re testing what you hope to use! 3.Find a friend “next door” to test with 4.Learn about ping, traceroute, Internet2 Detective, VRVS & what they can tell you 5.Start thinking about what roads you’ll travel to the next neighborhood(s)

How do you get from here to there? Can I figure out if my stuff might work?  Wouldn’t it be nice if you could figure out if there was any hope your stuff would work without having to buy/borrow/steal another expensive device to ship to each end point?  Wouldn’t it be nice if you could use a cheap PC to determine if there was any hope?  Wouldn’t it be nice if you could use free (or almost free!) software to determine if there was any hope?

Say “hi” to the Cakebox! Criteria: Small, inexpensive, easy to ship device No operator, no monitor, keyboard, or mouse required Just plug in a network cable & a power cable Provide user interface for non-network geeks (this was result of Rialto event debriefing)

Cakebox - cont -   Will allow you to do: Representative bandwidth testing Show you what “road” you’ll travel Allow you to exercise “broadcast” traffic You can find out if there is any hope  You can do this on your own!
