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 Traffic
Engineering Label-Switched-Paths (P2MP TE-LSPs) 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
substantially reduce power consumption on these routers. In this
paper, we propose a mechanism by which P2MP TE-LSPs are constructed
for carrying multicast traffic across multiple areas within a given
AS. We propose that these LSPs be built by using the advertisements
of the power-replication capacity ratio advertised by fine grained
components such as multicast capable line-cards of routers and multi-
layer switches deployed within an AS.
