Deployment Examples

The following number of slides illustrate examples of broad categories of deployments encountered in real-life. Of course the number of possibilities is endless and each customer's situation can be addressed in a tailor made fashion by mixing and matching from a variety of generic components developed by NetSys to compose meteorological information systems of any kind.

This diagram depicts a SADIS 1st to 2nd generation migration plan.

A deployment can be created where a new NetSys SADIS2g system runs in parallel with any legacy SADIS1g system for a transition period until the user is familiar with the new system after which the old system can be switched of.

The SADIS2g reception station can make use of the customer's existing SADIS1g Antenna and LNB. A Y-connector is used to split the coax for simultaneous signalling to the old and new systems.

This diagram depicts a typical briefing office setup.

For ISCS deployments no VADEDGE or nsTRANSCODER hardware is required. Instead, a Comtech model other than that used for SADIS deployments is used in conjunction with special pdreceive software on the servers.

For SADIS deployments, NetSys can supply either the in-house developed nsTRANSCODER (which is more cost-effective and the preferred option) or a vadEDGE unit to convert the HDLC frames emanating from the Comtech modem to TCP/IP.

In this example, dual redundant servers are deployed in a High Availability cluster configuration to ensure 100% uptime.

Briefing officer workstations are connected to the servers via high-speed LAN along with printers and fax modems.

The workstations and servers run any combination of the NetSys SADIS software packages to suit the customer's specific needs whether it be operational briefing or forecasting or both

This example differs from the previous in that the emphasis is on web briefings where the workload is shifted from the briefing office to the customer

The LAN is protected by a firewall to prevent security breaches and the application is access controlled by usernames and passwords to mitigate unsolicited use of the service.

NetSys can assist with the configuration of a Linux iptables based firewall or a CISCO IOS based firewall during commissioning of the solution.

An administrative web interface allows the operating authority to controll access, configure and monitor the web service.

For more information regarding the features of the web service software, please refer to the nsWEBPIB section under Products.

In this example the focus is on the collection of various kinds of data to serve as a data center for flight briefing and forecasting purposes.

Depending on geographical location, either ISCS or SADIS would populate a cluster configuration with the other serving as a backup data source.

The NetSys MSG reception station can be added to the configuration for added data and functionality.

The NetSys Message Switching System is ideally suited for this deployment scenario with a number of features to deal with duplicate messages and 1-to-many message dissemination. Apart from the normal WMO and ICAO conformant message switching capabilities, it also provides a powerful file switching module useful for MSG integration.

All-and-all, these features contribute to make inclusion of the MHS an attractive and viable setup as far as redundancy and functionality are concerned.

Some deployments have budgetary constraints or minimal requirements.

In such instances, NetSys can supply a setup lacking redundancy without compromising functionality. Customers opting to use the nsTRANSCODER hardware instead of an alternative will enjoy further cost benefits and added reliability.

In this instance, the client and server software are both deployed on a single high-end workstation. Due to the effective by which the data is decoded and stored there is little or no performance degrading from the user's point of view.

For ISCS installations of this kind though, it is recommended by the ISCS operator and NetSys shares this view, to have a seperate reception station for data collection which is then forwarded to the main workstation. This to prevent loss of data in the event of processing intensive client requests running in parallel with data reception.

User Interface Videos

The following number of slides illustrate examples of various modules in the graphical user interfaces. The clips provide a glimpse into the extreme ease and speed by which users can achieve everyday tasks. Videos are scaled down to reduce the byte size of downloads.
