Geo-replication systems  improve the distribution of data across geographically distributed data networks. This enables improved end-user experience of data heavy applications such as web portals. Geo-replication can be achieved using software, hardware or a combination of the two.  Geo-replication software Geo-replication software is a network performance-enhancing technology that is designed to provide improved access to portal or intranet content for uses at the most remote parts of large organizations. It is based on the principle of storing complete replicas of portal content on local servers, and then keeping the content on those servers up-to-date using heavily compressed data updates. Geo-replication software can dramatically increase the performance of data networks that suffer limited bandwidth, latency and periodic disconnection. Terabytes of data can be efficiently replicated over a WAN giving remote sites rapid access to web applications. Geo-replication software solutions use a combination of data compression and content caching technologies. differencing technologies can also be employed to dramatically reduce the volume of data that has to be transmitted to keep portal content accurate across all servers. This update compression dramatically reduces the load that portal traffic inflicts on networks, and significantly improves the end user experience of a portal by accelerating its performance . Differencing engine technologies To deliver this reduction in the size of the required data updates across a portal, geo-replication systems often use differencing engine technologies. These systems are able to difference the content of each portal server right down to the byte level. This knowledge of the content that is already on each server enables the system to rebuild any changes to the content on one server, across each of the other servers in the deployment from content already hosted on those other servers. This type of differencing system ensures that no content, at the byte level, is ever sent to a server twice. Offline portal replication on laptops Geo-replication systems are often extended to deliver local replication beyond the server and down to the laptop used by a single user. Server to laptop replication enables mobile users to have access to a full replica of their business portal on a standard laptop. This technology may be employed to provide in the field access to portal content by, for example, sales forces and combat forces.
