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 neighborhood1. 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?
