Let's distinguish the problems we're trying to solve:
* Cache consistency during updates: A local DAT cache which is not updated during a cache update event, thus needs to time out faster and a global DAT cache receiving regular updates with less need to update.
* Timely cache update: The global cache shall be updated as soon as the information is available.
My previous email focused on the former while your response is about the latter. Is that your assessment too ?
Both problems require solving to fully support this dynamic environment you are describing whilst reducing ARP traffic overhead.
Would you mind commenting on the cache consistency issue ? Antonio will respond to your 'snoop outgoing ARP Requests' question separately.
