WIS 2.0

...

prioritizes use of public telecommunications networks (i.e. Internet) when publishing digital resources[1].

Tip

BENEFITS:

  • Publishing digital resources on the Internet enables the meteorological community to retrieve or interact with those resources - it is unlikely that most of the community would be permitted to join managed networks such as Area Meteorological Data Communications Networks (AMDCN) employed by NMHS for data exchange with guaranteed service levels.

  • Internet connections are significantly cheaper than the same bandwidth delivered through a managed networks.

GISCs remain responsible for managing the telecommunications network(s) used in their Area of Responsibility (AoR) and for communication between GISCs - the Area Meteorological Data Communications Network (AMDCN) and WIS Core Network respectively[2]. In many locations, the Internet is now reliable enough for safety-critical applications - provided that those applications are built to be fault-tolerant. However, GISCs may deem that it is necessary to complement Internet connectivity with a high-performance managed network to meet program-specific service level requirements (e.g. warnings shall be transmitted end-to-end within WIS within two minutes [3]). The specification of the AMDCN (managed network vs. Internet) is a responsibility of the GISC, taking into account reliability, security, availability, cost/use ratio and capabilities at DCPCs and NCs.
