Reliable Multicasting for Power Optimization in Data Center Networks

Abstract

In Multicast Data Center network, Power optimization is a challenge since Data Center network is highly energy concerned as well as cost conscious.  The Energy efficiency of a Data Center network must always be high for reliable performance. Reliable Multicast in Data Center Networks, which minimize the packet loss and optimize the power consumption, is proposed. Energy Efficient Routing is proposed for power optimization. Energy Efficient Routing is done by shutting down the unused links during off-peak traffic times in the data center network. The backup Overlay algorithm is suggested to minimize the packet loss in Data Center networks. During high speed data transmission, the Backup Overlay handles packet loss and also responds to link failure and receiver failure causing curtailed CPU overhead.  This RDCM is basically designed for generic data center topologies. BCube tree is presented and simulation is carried out.  But they can be easily extended to other data center networks.  The proposed RDCM causes reduced Power consumption and reduced CPU overhead to datacenter servers.
