VLAN Switching is the most powerful implementation method that sets Just Add Power apart from all other manufactures of Video-over-IP products. VLAN Switching is our unique, out-of-the-box approach of using port-based VLANs to dynamically manage traffic flow on a network. By using a unique VLAN to keep each video stream isolated on a network, the heavy lifting of sifting through packets and managing IGMP membership is removed from the equation, and the switch is able to perform its most basic function: forwarding packets. JADConfig programs a switch for VLAN Switching.
In some installations, creating a parallel or dedicated network to take full advantage of VLAN Switching - such as integrating on top of an existing data network at an educational institution - is not a realistic or desirable approach. It makes more sense to have all Just Add Power devices in a single dedicated VLAN to keep them from interfering with the rest of the data network. With all devices in a single VLAN, switching sources involves modifying the Multicast IP of the Receiver rather than actively manipulating the VLAN configuration of the managed switch.
Hostname Switching describes a 2G System where all Just Add Power devices are in a single VLAN and switching is performed by modifying the Multicast IP of individual units. Each Transmitter is given a unique Multicast IP - referred to as a Channel - and a Receiver is assigned the Channel of the Transmitter it is meant to watch. The Channel is assigned to the Transmitter and Receiver via a TELNET command. When using Multicast Switching, switching speeds will not be instant and seamless like they are with VLAN Switching, but the results should be satisfactory given the more strict requirements of the specific project.
Hostname Switching is only for 2G Systems, or hybrid systems where all devices are in 2G Mode. For 3G Systems with single-VLAN requirements, please go to the Multicast Switching article.
