The number of packets SHOULD be throttled in order not to exceed peer's rate limits. If the limit gets exceeded, the connection MAY be dropped by the peer.
Two rate limits strategies are applied:
1) Number of packets per second
2) Size of packets (in bytes) per second
Both strategies SHOULD be applied per IP address, peer id and topic.
The size limit SHOULD be greater or equal than the maximum packet size.
