Abstract:
There is a need to simplify network operations for multicast
services. Current solutions require a tree-building control plane to
build and maintain end-to-end tree state per flow, impacting router
state capacity and network convergence times. Multi-point tree
building protocols are often considered complex to deploy and debug
and may include mechanics from legacy use-cases and/or assumptions
which no longer apply to the current use-cases. When multicast
services are transiting a provider network through an overlay, the
core network has a choice to either aggregate customer state into a
minimum set of core states resulting in flooding traffic to unwanted
network end-points, or to map per-customer, per-flow tree state
directly into the provider core state amplifying the network-wide
state problem.
