Abstract
A system for providing uninterrupted communication over a network link includes a multi-port switch that is connected to a first network portion and a second network portion that are communicating with one another. The multi-port switch is also connected to a separate server unit, such as a firewall computer. The switch is configured to direct communication signals flowing between the first network portion and the second network portion through the separate server unit for processing during normal operation. When the separate server unit fails, however, the switch is reconfigured so that communications bypass the separate server unit. In a preferred embodiment, a Ethernet switch having virtual local area network (VLAN) capability is used.
