RE: Differences between INT and MMT tables for address resolution?



Dear Harald,

a. I can also add, recalling the discussion within SatLabs (www.satlabs.org)
on the INT/MMT topic, additional conclusions of the SatLabs meeting on 1/2
April 2003 were that the INT table :

- is just too complicated. Already now people have different interpretations
on how to use it,
- allows not enough dynamics: multiple tables need to be scanned when e.g. a
new service/multicast group is introduced in the network,
- needs an official platform_id registration at DVB bodies: this means delay
and paperwork.

Therefore, MMT was preferred as a first step for interoperability between
DVB-RCS Hubs/Terminals.

b. Concerning the MMT dynamics, in a future regenerative DVB-RCS system  to
be launched in 2004,  the MMT will be  used, and by allowing IGMP to travel
over the satellite link and let the NCC update the MMT accordingly  some
degree of dynamics can be achieved.
