Abstract
An ARP table is stored in a gateway. The ARP table corresponds a first external IP address of a first application server to a first MAC address of a first external network card of the first application server, and corresponds a second external IP address of a second application server to a second MAC address of a second external network card of the second application server. The first and second application servers will check the statuses of one another to see if any of them fails. If the first application server fails, the first external IP address will be added to the second external network card, and the ARP table will be updated to correspond the first external IP address to the second MAC address.
