Abstract
Some embodiments of the invention provide a load balancer for distributing packet flows that are addressed to a group of data compute nodes (DCNs) amongst the DCNs of the group. In some embodiments, the load balancer includes a connection data storage comprising several different destination network address translation (DNAT) tables. Each particular DNAT table is defined at a particular instance in time and stores the identity of a plurality DCNs that are part of the group at the particular instance in time. Each time a DCN is added to the group, the load balancer of some embodiments creates a new DNAT table in the connection data storage for processing new packet flows, while using previously created DNAT tables to process packets that are part of previously processed packet flows.
