Application Layer Address Advertisements for Flexible Static Network Configurations

Disclosed is a method for application layer address advertisements for flexible static network configurations.

When multiple devices share the same Virtual Internet Protocol (VIP) address, only one device at a time may be the address owner as far as any one client is concerned. Anything that can lead to more than one device advertising ownership of an Internet Protocol ( IP) address on any one network at any one time is problematic, and anything that slows down the process of taking over an IP address or of releasing an IP address is also problematic. Despite this, the standard way applications that perform IP address takeover is to reconfigure the network interface on the host. This additionally leads to the problem that if the application fails the residual ownership of the IP address on the host remains, leading to multiple owners of the same address.

The disclosed method utilizes first an Address Resolution Protocol (ARP) or neighbor discovery service integrated into the application that controls IP address takeover. Then the host is configured to recognize but not advertise the virtual IP address. With this method, an application can have a static network configuration (it does not have to change how the host stack is configured despite IP address ownership changes). This approach allows for more responsive IP address takeover. There are no longer any external dependencies a...
