With ever-increasing demands for data exchange and the commensurate pressures on available bandwidth, iOra provides portal and file-based compression and replication solutions for improved at-sea access to crucial operational data, training and maintenance manuals, and administration documentation, thus enabling more effective and efficient collaboration between personnel on-board and staff ashore through the availability of more up-to-date portal content.

Organisations that operate routinely in the most demanding operational environments choose and trust iOra to ensure that their data exchange strategy is consistent and guaranteed at all times.

Document compression and data replication

iOra’s patented compression technology, Epsilon, compresses documents up to 99.9% and Geo-Replicator® replicates data between Microsoft SharePoint servers, or by creating virtualised servers or web applications for mobile users.

Vessels in geographically distributed locations operating at the edge of data-exchange webs are able to communicate more effectively over global, satellite-enabled systems and HF / VHF / UHF / VLF networks – even if they are periodically disconnected, have limited bandwidth or high latency – thus enabling near-real time operational continuity. As a result, Commanders have uninterrupted access to mission-critical information anytime and anywhere, providing a single point of truth in all operations.

iOra’s compression and replication software can provide ships at sea with access to critical documents.
iOra Geo-Replicator delivers highly compressed amendments to virtualised content and site structure through to remote laptop or mobile users.
iOra Geo-Replicator compresses and replicates data across limited bandwidth that is in high demand, often high latency or even disconnected.
iOra Geo-Replicator portal is identical whether online using high level networks or offline in a disconnected environment.
iOra Edge replication monitoring technology provides reports on the health and status of iOra Geo-Replicator, in both local and remote deployments.

iOra’s data compression and replication software makes it possible for military personnel to actively share information within a C4I environment across networks that have high latency, constrained bandwidth or intermittent availability.

iOra’s technology has been successfully integrated on tens of thousands of machines by military units, delivering data replication over bandwidths as low as 2kbps to disconnected users.

Epsilon – patented data compression engine

iOra’s patented compression engine, Epsilon, is the fundamental component of efficient replication operations. It is essential that the data to be sent over the network is minimised to execute best replication. Compression of data updates becomes particularly important where the network connection is challenging or where the end user is operating at the edge of the corporate network. Epsilon is the enabler for introducing new data-sensitive applications to remote users who would not be able to access data without efficient data transport.

Geo-Replicator – data replication technology

Geo-Replicator scopes the data to be replicated and the process for delivering updates. Reports can be generated to detail the content replicated or the update status of specific end users. Administrators can set operational rules to apply automatically to manage the effects of replication in terms of managing data conflicts with conflict resolution in Server-to-Server networks.

Template files can also be configured to control the manner in which Geo-Replicator manages the captured content when disconnected from the network for web applications. Once all of the individual pages (and the rules for handling them) have been identified, an exact replica of the information is prepared for delivery to the remote user. There is no need for re-coding or re-development in Geo-Replicator; it is the very same pages that are used offline as online. Once this initial batch of content has been downloaded onto the user’s laptop, the user can then work with the web pages through a standard browser. All the functionality that the user would expect online (e.g. search) is available on the laptop, whether it is connected to a network or not.

iOra Geo-Replicator operational modes:

Server-to-Server (S2S)

The master and replica servers check against their local content repositories on an update schedule that is dictated by the volatility of the data. Scheduled operation ensures that server peak usage can be efficiently managed and avoids potential system overflow that can occur when triggering incremental replication on each and every server update event.

Geo-Replicator uses the SharePoint platform API to read and write the structure, content and access rights changes on the master and replica. The update amendments that are passed between the master and replica server benefit from the high levels of compression that can only be achieved by the Epsilon technology. Hence the network connection that is required to connect master and replica can be anything from 1kbps to 100Mbps. In the same regard the bandwidth used by the replication phase is dramatically reduced.

Server-to-Laptop (S2L)

iOra’s software ensures offline mobile and field workers dependent on laptop connectivity have exactly the same experience as they would if working at Head Office. Whilst offline web page links in web pages work, when online documents can be updated and full search of the offline content is available.

Server-to-Virtual Server (S2VS)

This solution is specially designed as an alternative for lightweight, read-only portals for remote offices solving the problem of replicating portal content to remote office environments where the installation and maintenance of a sophisticated server is impractical. iOra is deployed at the server level with the addition of a proxy server, to deliver a web application to a group of users without the requirement for installing backend infrastructure.

Replication monitoring interface

iOra’s Edge replication technology monitors the health and status of iOra Geo-Replicator, monitoring both local and remote deployments.

iOra Edge provides a monitoring interface that can either be used as a high level digital dashboard for users who solely want to assess operation status for all connected nodes of the network, or an interface that additionally provides the drill-down capability to support fault finding and problem resolution.

iOra Edge gives a company’s HeadQuarters and Network Operation Centre full reassurance that their fleets have the latest critical orders before exercises and missions, removing time and uncertainty issues.



Epsilon Compression

iOra Epsilon is the iOra patented compression engine that is the core component of all iOra replication configurations.

iOra Edge

iOra Edge replication monitoring provides a tool for reporting the health and status of iOra Geo-Replicator replication systems, and monitors both local and remote deployments.

Sharing Data over Challenging Military Networks

This paper describes the challenges for sharing data in deployed environments and how they are then complicated by the performance of the available military networks in ensuring a consistent and holistic view of data.

Data Replication Case Study: US Navy

iOra's Geo-Replicator technology provides the bandwidth optimisation that makes the updating of the 'Distance Support' portal possible across the entire fleet via satellite, enabling the navy to run an up-todate portal on all of its ships and substantially reducing demand on the navy's satellite network, as well as the cost of transporting experts to ships.

Case Study: Remote Information Access for Christian Aid

By providing remote aid operations with improved access to information, iOra's Geo-Replicator helps Christian Aid be more agile and responsive to local needs enabling it to deliver more effective development work worldwide.

Big Data over Limited Networks

This paper examines the emergence of Big Data repositories and the particular problems that are encountered when these data sources need to be transmitted over limited military networks.

iOra Wins MOD Contract Worth More Than £1.5m

The MOD has awarded a contract worth more than £1.5m to iOra for the supply licences for fixed and deployed nodes of the iOra Geo-replicator replication and compression solution.
