[ghpn-wg] Fwd: [e2e] Closestnode.com announcement

[Franco Travostino]

In our parlance, this would be an instantiation of Grid Network Service. One
that enables some clever late-binding between services.

We are writing to announce closestnode.com <http://closestnode.com>, a free,
non-commercial
service that we have recently deployed for directing clients to servers
and peers that are close to them.

Closestnode.com <http://Closestnode.com> can be used for mapping clients to
the closest DHT node,
for selecting a nearby mirror a user can download content from, or for
finding the closest game server a user can connect to in multiplayer
online games.

The service is very simple to use: You register a unique application
name with us on the web (e.g. mycoolapp) and either link our library
into your application or run our standalone program along your server
nodes. Once that is done, any node performing a DNS lookup for
mycoolapp.closestnode.com <http://mycoolapp.closestnode.com> will receive
the IP address of the the closest
(lowest latency) node to itself that is currently running the mycoolapp
application.

Closestnode.com <http://Closestnode.com> can be used to implement a generic
anycast service. It
supports hosts behind firewalls and NAT boxes. One caveat is that a cold
lookup with unprimed caches may take up to a few hundred ms, so this
system is best suited for distributed systems where sessions last a few
seconds or more.

More information, code and demos are available at
http://www.closestnode.com. The system is an offshoot of recent research
at Cornell university, described in the following paper:

Don't hesitate to contact us if you have any questions.

Best,
Bernard,
Alex,
Gun.
