Hi everyone,


I have installed kea-dhcp opensource for providing IP to network device in the my company.

Kea is work very good with : total of device < 800k device . But when total of device reaches 1M  device , kea seems has a problem:

-          When so many request come to KEA ( 400 rqs/s )  ( exceed request that KEA can process , results of  my load testing for my server is 248 rqs/s). So when KEA sent OFFER(type 2) message to client  >>>  Client : sent ACK ( type 5) to KEA server.  but  KEA is processing other request (type 2) ( full 248 rqs/s) so  KEA can not more received  request  ACK ( type 5). ==è client received IP after  many time sent offer ( affer client sent discover 30 minute or later)

So I have ideal :  How to configure KEA to process 248 rqs ( offer message )  and drop offer message  come late ( after request 248). Then completed processing total these 248 requests , KEA continutes receive and process the other 248 requests. That mean, Each time KEA just process 248 offer message and drop other reques come.


Thank you,
