Using UDP rather than TCP in this case might make sense.

Originally posted by TheRefactornator View PostI did consider this as an option but as I understand it, UDP does not transport well over the internet because UDP packets are likely to be dropped by routers along the path.
UDP is used by all popular online games.
It is indeed not reliable protocol but you can easily solve this by adding counters and confirmations via UDP too.
UDP is ideal for small packets and cases when server needs to process lots of those packets.
Are you going to run this on LAN? If not you need to think about security for the data you send over public networks.Comment

This will not run on the LAN so I've already considered encryption, but the sensitivity of the data will need to be confirmed by the vendor so I'm not sure if encryption is required yet.Moving to Montana soon, gonna be a dental floss tycoonComment

Realtime means that the time taken is quantifiable, not that it's fast.
Stick to noddy .NET "apps".Comment

These are robust pieces of kit and used by the likes of telcos.
They'll do lots of different LB algorithms, round-robin, least loaded, sticky, non-sticky, etc, etc.
Depends what your requirements are and how much you're willing to spend.
I wouldn't touch Windows NLB with a barge pole if this is for a highly-available production service. App health awareness is non-existent. I've seen NLB systems loadbalancing requests quite happily to systems throwing .NET server errors. There are workarounds, but not simple. With the hardware option you can at least put some intelligence in there to spot this.

By that definition, Royal Mail 1st Class is realtime.
