Evaluation of the UDLR environment Takeshi Usui Takeshi@sfc.wide.ad.jp
Today my presentation Introduction about my research topic The evaluation of the UDLR network environment Introduction of the monitoring for UDLR Request to each UDL operators from me
Introduction of my research topic The evaluation of the UDLR network environment The Background The UDL partners usually have the narrow band link for the terrestrial return link The traffic from the partners go throughout the narrow band link to Feed. For the narrow terrestrial link,partners can t use the UDL effectively.
UDL is wide-area broadcast link,but return link is point to point. The ability of Return link is various.
Motivation Much Data traffic go throught the UDL,but the terrestrial return link is necessary Web browzing request packet File transfer request packet We want to have a bidirectional communication using UDL Using Audio,and Movie
AI3 network Narrow band Qos available Point Receiver (many) Feeder ISP Partners ISP
My research topic What is minimum requriment of the terrestrial link for some application QoS is effective or not in Border Router This is depending of the partners network I will research
Now I monitor the nature of UDLR network What a kinds of application is used? How much bandwidth is used? I classify the UDLR network environment Application using is effectiv or not What kinds of return link do we need the UDL link? QoS is effective or not
I summary these to http://udl-monitor.ai3.net/.http://udl-monitor.ai3.net/ Please see the page.
My request to UDL operators I want to research the nature of the terrestrial link Bandwidth,Packet loss,Straight delay Please make my account to the UDLR Router in your network I set up the measurement program in your router By using the data,I classify the UDLR environment
Next step I research what a kinds of QoS technology is effective Ex. Any queueing technology,duplicated packet methods I design the tunnel relay router,which purpose reduce the feed load,and decrease the pass router.
