Hi,
For those of you who are attending IETF 80, you have a choice to try out the
interop demo from NeuStar and Juniper. Total time of execution is less than 5
minutes.
The test environment is currently setup to demonstrate the ALTO-enabled HTTP
Redirect server. In particular, it shows use of the following cost map
definitions:
"IETFWiFi" : {
"Neustar209" : 200 ,
"Neustar156" : 300
} ,
"IETFaWiFi" : {
"Neustar156" : 200 ,
"Neustar209" : 300
}
Here are the simple steps:
1- Connect to 'ietf' WiFi network and point your browser to
http://www.sample.neustarlab.biz:8000
a- The browser performs a DNS query to resolve www.sample.neustarlab.biz. The
resulting A RR points to HTTP Redirect server
b- HTTP Redirect Server performs the Endpoint Cost query to the Juniper ALTO
server. The ALTO response returns a higher precedence for the content server
with name www1.sample.neustarlab.biz, which is returned in the 307 HTTP
Redirect response from the Redirect server.
c- Next, the browser loads the content from www1.sample.neustarlab.biz
2- Disconnect from 'ietf' and reconnect to 'ietf-a'.
- steps a- thru c- above apply here as well.
- Since the source of the request is from a different network prefix, this
time the browser will load contents from www2.sample.neustarlab.biz
Lastly, if you tried this test earlier this afternoon, it probably didn't work
as well. The test environment was setup to demonstrate ALTO-enabled BIND
instance. It worked correctly until IETF NOC introduced a DNS proxy in the wee
hours of the night.
As always, if there are any questions or observations to share, please let us
know. The test environment will be available throughout the week, and very
likely for a lot longer beyond this week. And if you want to get a feel for
NeuStar ALTO server implementation, it is available at
http://alto-outside.neustarlab.biz:8080.
thanks,
-Syed
