This works whether the reservation is in memfile or one of the optional database backends.</font></div><div style="margin: 0px; font-stretch: normal; line-height: normal; min-height: 14px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; line-height: normal; min-height: 14px;" class="">- HIGH AVAILABILITY improvements. </div><div style="margin: 0px; font-stretch: normal; line-height: normal; min-height: 14px;" class="">We have improved the way the HA pairs update active leases, using paged updates (rather than one larger update) with changes to the dhcp-disable timer to ensure the lease synchronization completes before the HA member resumes service.</div><div style="margin: 0px; font-stretch: normal; line-height: normal; min-height: 14px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; line-height: normal;" class=""><font face="Arial" class="">- CONGESTION CONTROL. </font></div><div style="margin: 0px; font-stretch: normal; line-height: normal;" class=""><font face="Arial" class="">Kea processes packets sequentially, processing the oldest packets first (FIFO). When the backlog is too large, the FIFO algorithm means Kea may waste time processing requests from clients who have already stopped waiting for a response while still-active requests languish in the queue. </font></div><div style="margin: 0px; font-stretch: normal; line-height: normal;" class=""><font face="Arial" class="">In Kea 1.5 we have </font><span style="font-family: "Open Sans", sans-serif; font-size: 13.5px; font-variant-ligatures: normal; orphans: 2; white-space: pre-wrap; widows: 2;" class="">implemented a replaceable packet-queuing mechanism</span><font face="Arial" class="">. </font><span style="font-family: Arial;" class="">Our solution provides a ring-buffer mechanism by default, plus a new hook that will enable you to replace our algorithm with one of your own. </span></div><div style="margin: 0px; font-stretch: normal; line-height: normal;" class=""><font face="Arial" class=""><br class=""></font></div><div style="margin: 0px; font-stretch: normal; line-height: normal;" class=""><font face="Arial" class="">- New premium CLIENT CLASSIFICATION Commands hook library allows you to modify client class configuration via the REST api.
