Abstract
Disclosed is a method for managing flow tables at a switch in a network. The method includes establishing a static rule to distribute a first flow to a first server and a second flow to a second server and monitoring a first load on the first server and a second load on a second server. When, based on the monitoring, the first server is running at capacity and the third flow is to be distributed to the first server according to the static rule, the method includes establishing an exception to the static rule to yield an exception rule, distributing the third flow to a third server with capacity according to the exception rule and storing a flow table for the third flow at a switch, wherein the switch does not store a static rule flow table for the static rule.
