Abstract:
Power consumption in multicast replication operations is an area of
concern and choosing suitable replication points that can decrease
power consumption overall assumes importance. Multicast replication
capacity is an attribute of every line card of major routers and
multi-layer switches that support multicast in the core of an
Internet Service Provider (ISP) or an enterprise network.
Currently multicast replication points on Point-to-Multipoint
Multicast Distribution trees consume power while delivering multiple
output streams of data from a given input stream. The multicast
distribution trees are constructed without any regard for a proper
placement of the replication points and consequent optimal power
consumption at these points.
This results in overloading certain routers while under-utilizing
others. An optimal usage of these replication resources could reduce
power consumption on these routers bringing power consumption to
optimality. In this paper, we propose a mechanism by which Multicast
Distribution Trees are constructed for carrying multicast traffic
across multiple routers within a given network. We propose that these
Multicast Distribution Trees be built by using the information
pertaining to power-replication capacity ratio available with fine
grained components such as multicast capable line-cards of routers
and multi-layer switches deployed within a network.
