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,
