Is <strong>RPL</strong> Ready for “prime time” ? • Lots of ideas coming from deployed networks • More than 15 implementations including several commercial products this year • Stable specification (One last IESG DISCUSS, Routing metrics, trickle approved) • Two interoperability test events took place (earlier revision): • IPSO (Storing mode) • Zigbee/IP (Non-Storing modes) – Adopted by Industry alliances: Zigbee/IP, Wavenis, IEEE P1901.2, … Copyright © 2009 Cisco Systems, Inc.
