A connection publishing method for a distributed load balancer in which a router receives packets from at least one client and routes packet flows to multiple load balancer (LB) nodes, which in turn distribute the packet flows among multiple server nodes. A load balancer (LB) module on each server node determines and publishes a list of active connections between client(s) and the server (a connection publishing packet) back to the LB nodes. The LB module may randomly select a LB node to receive the packet. Upon receiving the packet, the LB node processes the connection information in the packet, distributing the connection information among appropriate LB nodes. Receiving the connection publishing information from the server nodes refreshes leases for the connections on the LB nodes. |
