All things related to multicast

[Leonard Giuliano <>]

Folks,

On the last Mcast WG call on 9/28, we discussed a proposed Multicast 
Overlay solution and there seemed to be strong consensus to recommend it 
going forward. Perhaps I didn't appreciate the swiftness of the migration 
from old network to new or maybe I just wasn't paying close attention to 
the timelines, but I kind of assumed this would be somewhat of a 
make-before-break approach and the new solution would be in place before 
the old network was dismantled.

In any event, we are now seeing the disconnecting of the multicast 
connectivity that was supporting some active applications. Specifically, 
the Multicast Menu (https://multicastmenu.herokuapp.com/) which listed and 
launched access to all the multicast content on I2 and GEANT, as well as 
plans for new multicast-based distance learning/educational content stream 
from a member (Thomas Jefferson HS) are now unavailable. The suggestion 
from the NOC to "implement GRE tunnels or transition their applications to 
Layer 2 multipoint VPLS/EVPN" is not a viable option for interdomain apps 
designed to be globally available to the full R&E community.

In any event, now that the old multicast-enabled network is no longer 
available, how soon could we get the new Mcast Overlay solution in place?


Thanks,
Lenny
