IceUpdate is the communications component of the Windows IceCast suite; it provides a fast and efficient means of transferring data from an IceCast server (or the Global Bureau) to a local workstation.
IceNetUpdate utilizes an Internet-based connection to download the data negating the need for a Dial-up connection and modem. It creates a secure SSH tunnel over the Internet, through multiple firewalls between the Global Bureau and a local machine.
IceNetUpdate is at its most efficient using a permanent networked Internet link. IceNetUpdate can also download data once a machine is connected to an independent Internet Service Provider (ISP) via a dial up modem.
The below pictures show IceUpdate and IceNetUpdate as the appear when downloading sensor and forecast data.
