ACTIVE HOST AND BACKUP HOST IN A HOST ARRANGEMENT FOR COMMUNICATING WITH A TERMINAL CONNECTED TO AN IP NETWORK

摘要

A method in a host arrangement for communicating with a terminal connected to an IP communication network. The arrangement comprises at least two hosts, one operating as active host and the remaining at least one host operating as backup host(s). The arrangement is connected to the IP communication network by means of a switch, wherein each host of the arrangement is connected to the switch by means of an individual link, the active host being associated with an IP and a MAC address. The method comprises detecting a link failure between the active host and the switch, or a malfunction of the active host, and determining a backup host to take over. The method comprises associating the IP and the MAC address of the active host to the determined backup host to take over, and triggering a MAC learning process in the switch.
