METHODS AND DEVICES FOR DETECTING SERVICE FAILURES AND MAINTAINING COMPUTING SERVICES USING A RESILIENT INTELLIGENT CLIENT COMPUTER
First Claim
1. A computer-implemented resilient client failover method to maintain an up-to-date shared application service, the method comprising:
- determining, with an intelligent client computer, a level of currentness of a primary site;
detecting, with the intelligent client computer, that the primary site is unavailable;
assessing, with the intelligent client computer, a level of currentness of a secondary site;
determining, with the intelligent client computer, updates made by the intelligent client computer to data for updating the primary site; and
replaying, by the intelligent client computer, the updates to the data made by the intelligent client computer to the secondary site.

Abstract
Intelligent client computing devices track and record the changes they make to data, applications, and services. Systems, devices, and computer readable media for detecting service tier failures and maintaining application services provide a resilient client architecture that allows a client application on an intelligent client to automatically detect the unavailability of server tiers or sites and re-route requests and updates to secondary sites to maintain application services at the client tier in a manner that is transparent to a user. The resilient client architecture understands the level of currentness of secondary sites in order to select the best secondary site and to automatically and transparently bring this secondary site up to date to ensure no data updates are missing from the secondary site.

21. An intelligent client computer device configured to implement a resilient client failover to maintain an up-to-date shared application service, the intelligent client computer device comprising:
-
a client object factory configured to determine a level of currentness of a primary site; and a link to a control console storing a latest copy of an application services routing table, the intelligent client computer device configured to detect that the primary site is unavailable by accessing the application services routing table; wherein the client object factory is further configured to assess a level of currentness of a secondary site, determine updates made by the intelligent client computer to data for updating the primary site, and to replay the updates to the data made by the intelligent client computer to the secondary site. - View Dependent Claims (22, 23, 24, 25)

26. A computer-implemented resilient client update method using an active secondary site, the method comprising:
-
determining, with an intelligent client computer, a level of currentness of a primary site; determining, with the intelligent client computer, updates made by the intelligent client computer to data for updating the primary site; synchronously posting, with the intelligent client computer, the updates made by the intelligent client to the primary site; assessing, with the intelligent client computer, a level of currentness of a secondary site; and asynchronously routing the updates to the data made by the intelligent client computer from the primary site to the secondary site.
