Abstract
A network system includes a first network access device having an input/output (IO) module of a firewall to capture a packet of a network session originated from a first node associated with the first network access device, a first security device having a firewall processing module to determine based on the captured packet whether the first node is a destination node that is receiving VM migration from a second node that is associated with a second network access device. The first security device is to update a first flow table within the first network access device. The network system further includes a second security device to receive a message from the first security device concerning the VM migration to update a second flow table of the second network access device, such that further network traffic of the network session is routed to the first node without interrupting the network session.
