How does it work iMPath N e t w o r k s L3 Switch/Router L3 Switch/Router Digital Backbone; ATM, SONET, LAN, Gigabit Ethernet... L3 Switch/Router L3 Switch/Router L3 Switch/Router L3 Switch/Router 100 Meg Encoder The Routers build and share a table of all the “IGMP servers” available on the network. They keep a table of all the available Multicast Addresses This Router will not forward any of the multicast traffic until it receives a request from a decoder (client) Decoder The Encoder is considered a “server” in the IGMP world. It generates a video signal that will be made available to any Decoder (client) on the network. The Encoder transmits a signal with a distinct destination address. Between 224.x.x.x to 239.x.x.x. (some addresses are reserved for specific applications) Virtual Matrix Control Console •Displays video to monitors •Controls camera PTZ Typical field encoder collector network Control Center # 1
