UDLR
• Uni-Directional Link Routing– Working Group in IETF (UDLR-WG)– WIDE Project, INRIA, Huge and others
• Routing Issues for Network with Uni-Directional Link

Uni-Directonal Link
• Feasible Model for Network with Satellite and Terrestrial Link– Many Receivers and Few Feeder– Satellite Downlink, Terrestrial Uplink

Routing and UDL
• Current Routing Technology– No assumption for Network with UDL

UDLR Technology
• Using Current Dynamic Routing Protocol on Network with UDL– Setting Vritual Return Channel by Tunneling– Dynamic Tunnel Configuration
