Design Considerations For MVPN

Design Considerations For MVPN

When deploying a multicast VPN service, providers try to optimize multicast traffic distribution and delays while reducing the amount of state. The following considerations have given MVPN providers direction in their MVPN deployment:
a) Core multicast routing states should typically be kept to a minimum.
b) MVPN packet delays should typically be the same as unicast traffic.
c) Data should typically be sent only to PEs with interested receivers.
e) Number of multicast routing states.
f) Overhead of managing the RP if PIM-SM is used
g) Difference of forwarding delay between shared tree and source trees which are very important.
