Subject RE: UDP Site-to-Site
Date Fri, 04 Dec 2015 16:15:32 GMT
Mark,

We have a legacy system that uses a custom UDP-based messaging protocol to
replicate data across database instances (in the 10 - 20 range). Depending
on system deployment configurations, some instances may be connected to the
network via unreliable low-bandwidth links. UDP multicast is used instead of
point-to-point TCP to limit bandwidth usage, since, in most cases,  the
majority of instances are connected via reliable high-bandwidth links. It's
therefore more efficient, the argument goes, to send repeats for the
occasional dropped packets for the minority of disadvantaged nodes instead
of duplicating each and every packet for point-to-point TCP connection to
each node.

Could a similar mechanism be implemented easily using NiFi?

Francois,

Currently, the site-to-site protocol uses only TCP. Can you explain the use
case that you had in mind so that we can understand how we might be able to
improve this going forward, or perhaps provide suggestions of how else to
accomplish your goals?

Thanks
-Mark
