SMART APPROACH to COMMUNICATIONS


Private corporate networks: ensuring secure and efficient performance. By Volker Jarsch


Oil & gas players can greatly benefit from private corporate networks


E


nterprises in the oil & gas industry demand secure, reliable and effective communication between exploration sites and production labs. Tis includes broadband access to public networks from all sites. Essential to enterprise success is not only access to information systems and shared processing and storage resources, but also fast and secure data exchange between the branches at different locations and with business partners. Tere is growing awareness that this network and communication backbone, on which many business processes rely, demands particular availability and security. In the case of oil & gas enterprises with their


remote offshore and land locations, they have unique real-time and quality of service (QoS) requirements for reliable communications, connectivity, and complete data protection. Te ideal solution, from the IT manager’s perspective, would be completely private lines between the production and drilling platforms, the labs, forwarding and storage sites, and the shared IT tools and databases in the company headquarters. Tis is difficult to achieve – if at all possible – and


would be far too expensive. Terefore, current communications solutions use terrestrial public networks, line-of-sight or satellite, which are far from fully satisfactory. In response to this gap in the market is an


innovative new solution from German technology enterprise ND SatCom: SKYWAN 5G. Tis solution ideally fulfils the unique requirements of diverse customers, including oil & gas, as detailed below.


DIRECT SINGLE-HOP CONNECTIONS Te IT of each site (not including a central hub that is hosted at service provider’s teleport) is extended with a small IP router that communicates via satellite with the same routers at the other sites. Te connections occur in one single hop and thus avoid firstly the ‘double hops’ known from the usual satcom systems and secondly, data forwarding via third-party terrestrial routes. Te SKYWAN 5G router supports user data rates from a few kilobits up to 20 Megabits in both directions.

SELF-ADAPTING TO ACTUAL THROUGHPUT Obviously, the data rate to be transmitted out of a site is highly variable and changes instantaneously. Cost-effectiveness demands that – on the one hand – the user data rates shall be supported as required by the application and response times shall be minimised, whereas – on the other hand – the monthly satellite capacity bill shall remain well within the IT budget. Tis is achieved by SKYWAN 5G’s highly adaptive satellite capacity management
