Adding networks

If your system spreads across multiple networks or you allow your users to connect to the main server over the Internet, you must configure the network view and add additional networks.

To add a network:

1. Open the Network view task.
2. If you are creating a subnet, select the parent network in the network tree. Otherwise, select the Default network.
3. Click Network (), and enter the name of the network entity.

   You are automatically placed in the network’s Properties tab.

4. From the Capabilities drop-down list, select the data transmission type for streaming live video on the network.
   TIP: Always select the largest set of capabilities that your network supports.
   • Unicast TCP:

     Unicast (one-to-one) communication using TCP protocol is the most common mode of communication. It is supported by all IP networks, but it is also the least efficient method for transmitting video.
   • Unicast UDP:

     Unicast (one-to-one) communication using UDP protocol. Because UDP is a connectionless protocol, it works better for live video transmission. When the network traffic is busy, UDP is much less likely to cause choppy video than TCP. A network that supports unicast UDP necessarily supports unicast TCP.
   • Multicast:

     Multicast is the most efficient transmission method for live video. It allows a video stream to be transmitted once over the network to be received by as many destinations as necessary. The gain could be very significant if there are many destinations. A network supporting multicast necessarily supports unicast UDP and unicast TCP.

     NOTE: Multicast requires specialized routers and switches. Make sure you confirm this with your IT department before setting the capabilities to multicast.
5. Under the Routes section, verify that all the routes created by default are valid.
   • You may have to change the default capabilities, or force the use of private address when public addresses cannot be used between servers within the same subnet. To edit a route, select it in the list and click Edit the item ().
   • If there is no connection between this network and another network on the system, select the route, and click Delete ().
   • You may want to add a direct route between this network and another child network, bypassing its parent network.
6. Click Apply.
