Title: LOAD BALANCING
Abstract:
Load-balancing data messages are sent by a source node to one or more different groups of destination compute nodes (DCNs). A load -balancer in the source compute node's egress datapath receives each data message sent from the source compute node and determines whether the data message is addressed to one of the DCN groups for which the load-balancer spreads the data traffic. When the received data message is not addressed to one of the load-balanced DCN groups, the load-balancer forwards the received data message to its addressed destination. When the received data message is addressed to one of the load-balancer's DCN groups, the load-balancer identifies a DCN in the addressed DCN group that should receive the data message, and directs the data message t the identified DCN by changing the destination address in the data message from the address of the identified DCN group to the address of the identified DCN.
