Multicasting is a method of transmitting a single stream of data
to multiple clients. Multicasting is connectionless; clients
receive a multicast by monitoring a specific multicast IP address
To successfully use multicast delivery with your server, your network must use multicast-enabled routers. Multicast-enabled routers are routers that are able to interpret class-D IP addresses use the Internet Group Management Protocol (IGMP) to route clients to the multicast IP address.
All multicast content must have a specified time-to-live value that limits the number of routers that the multicast can traverse before it expires.
The WMS Multicast Data Writer plug-in controls how the server uses multicast delivery with your publishing point. This plug-in is disabled by default and can only be enabled on broadcast publishing points.
