This results in high-quality, high-bandwidth video streaming without affecting Internet surfing or IP telephony
on adjacent ports. The gateway also supports IGMP proxying to allow forwarding of multicast packets at Layer

IV.VI MANAGEMENT & CONFIGURATION
This family of devices is designed for high volume deployment, this is reflected in the Zero Touch Configuration
model, whereby no user intervention is required when installing a unit. ZTC provides intelligent and automatic
configuration of remote RG units. It analyses incoming status information from each RG unit and dynamically
creates the appropriate configuration file or operating system download as required, it then selects the
appropriate download mechanism (e.g. TFTP,HTTP, HTTPS etc.) to complete the process. The ZTC client in
the RG initiates the download process on power up, or on expiry of its DHCP lease timer. ZTC provides
secure authentication of client devices, resilience through distributed server operation and in-built scalability
for very large networks.
