Network Weather Service

The components of a NWS resource monitoring system:

• a nameserver, a centralized controller, that keeps a registry of all components and monitoring activities;
• sensors, that produce resource observations;
• memories, that store resource observations;
• forecasters, that process resource observations;

Limits of the NWS architecture, bound to the presence of the nameserver:

• a communication bottleneck;
• a single point of failure;
• no security;
