The Hitch Hiker's Guide to the User Friendly Multicast

We publish our work in Data Communications International On-line Dec99-Feb00

TEN-155 network currently runs multicast on all production routers. The backbone is entirely native and sparse mode, multicast runs on the same physical infrastructure together with unicast data. Most of the connected National Research Networks have also native connections. All connections between all participants are done via PIM-SM/MSDP/MBGP. The previous DVMRP cloud was entirely replaced by a PIM-SM domain in the backbone. We plan to introduce the "production" multicast service soon, which means mainly a specification of the service and establishment of operational procedures. The draft of service specification is available here

The detailed current topology and the current status can always be found here.

An experimental per group monitoring system is available here. It requires dedicated SUN WS, so currently is run in a very limited version and if someone touches the WS, the data is usually deleted and whole system needs to be re-built -).
