Hi Arthur

You are always guaranteed to receive the packets from each client in the same order as they were sent, so using multiple ringbuffers is definitely a solution.

As soon as all the ringbuffers contain at least one packet you can pop one packet from each of the buffers and process them in parallel.

Best regards

Thank you Torbjørn!

Do you have some best practice to synchronize these packages afterwards? My first thought is to use Ringbuffers ...

Best regards

Arthur

The notifications are forwarded as they are received, you don't have any control over this unfortunately.

First off if you are sending a lot of data you will typically receive multiple packets pr connection event, which is why you are seeing groups of notifications from the same server.

Secondly, if there is any packet loss between one server and the client this will delay the packet transmission, and the server will have to "catch up" on following connection events, leading to a varying number of packets being sent on each event.
