SYSTEM AND METHOD FOR PROVIDING HYBRID ON DEMAND SERVICES TO A WORK UNIT

摘要

The present document describes a method and system for providing Hybrid On Demand (HOD) software and/or data to a plurality of normal nodes associated with a work unit. The normal nodes are serviced via two or more parent nodes using different communication networks. Normal nodes, which are connected to the Local Area Network (LAN) of the work unit, may receive software and/or data services from a local node via the LAN, and normal nodes which are outside of the LAN may receive software and/or data services from a SUPR node via a Wide Area Network (WAN) such as the internet. After synchronization with one the normal nodes, the parent nodes synchronize the updated data with each other, and then they push the updated data to all the normal nodes associated with the work unit to mirror the same data on all the normal nodes. Frequencies of synchronization and provision of software and/or data services and/or updates is governed by a set of synchronization rules that are embedded in the business layer of the nodes. This scenario may also be used for synchronizing data in a cache cloud manner between the different nodes of the wide and the local networks.

1. A method for synchronizing data in a cache cloud environment comprising client nodes associated with a work unit and parent nodes, the parent nodes comprising a SUPR node accessible via a wide area network (WAN) and a local node accessible via a local area network (LAN), the method comprising:
searching for closest parent node when new data is available at one of the client nodes; synchronizing new data with the closest parent node; synchronizing parent nodes with each other; pushing new data to all client nodes of the work unit.
