Learn about Traffic Engineering mechanisms that enable power savings in network infrastructure through this 38-minute conference presentation from NANOG. Explore how networks can reduce energy consumption during off-peak hours by implementing Power Groups (PG), a hierarchical abstraction system that organizes network interfaces based on their power characteristics. Discover how Traffic Engineering path placement algorithms can optimize power usage by distributing traffic across all Power Groups during peak hours and strategically starving selected groups during low-traffic periods to enable power-down capabilities. Examine the proposed IS-IS mechanisms for distributing power group information throughout the network. Gain insights from Distinguished Engineer Colby Barth's expertise in routing protocols and Traffic Engineering applications, drawing from his extensive experience in designing and operating IP/MPLS networks.
