Server maintains a queue of outbound packets for each user

Packets which are older than MAX_QUEUE_TIME are discarded

Each incoming request to the server takes up to MAX_BATCH_DOWN bytes
from the queue and returns them as the POST response body payload

Each incoming request contains up to MAX_BATCH_UP bytes of payload.
It's a multipart/form-data.
