Abstract

The embodiments disclosed herein select and assign a floating IP address (FIP) to an application based on characteristics of the application. Floating IP addresses are assigned a classification, and one or more network adapters are mapped to a FIP according to the FIPs assigned classification. The endpoint of a connection for an application initiating a network connection with a target application may be assigned a floating IP address according to attributes of the application being consistent with the classification of a FIP. Applications may be grouped according to their respective classification, and the group of applications may share a corresponding FIP. FIPs may be dynamically configured for an application with mapped network adapters selected based on the attributes of the application. An application's characteristics may change during executions, and the network adapters mapped to the FIP assigned to the application's connection may be reassigned.

Dependent claims

A method comprising:

configuring a plurality of floating IP addresses for a system, the plurality of floating IP addresses comprising (a) a first floating IP address that is associated with a first set of performance characteristics and (b) a second floating IP address that is associated with a second set of performance characteristics;
wherein the first set of performance characteristics and the second set of performance characteristics are each associated with respective levels of connection reliability and connection speed;
wherein the first set of performance characteristics and the second set of performance characteristics are different with regard to at least one of:
connection reliability and connection speed;
responsive to receiving a request to assign a floating IP address to an application:
determining an application classification for the application;
mapping the application classification to the first set of performance characteristics associated with the first floating IP address;
selecting the first floating IP address, from the plurality of floating IP addresses, for use by the application as a source address based on the mapping of the application classification to the first set of performance characteristics associated with the first floating IP address;
and
assigning the first floating IP address to the application.
