Outline A brief summary of DVTS application Applications Routing Measurement A proposal for DVTS-specific measurement tools Basic tool Access interface Find the server alone the path Server registration

A brief summary of DVTS application

DVTS features Hardware is based on consumer products Software is free and open source Useful for serious applications Special demand for network support 30Mbps, single video stream

Network challenges AS2 AS3 AS1 Bad cabling Wrong speed access Bad cabling Wrong speed Wrong duplex mode firewall Bandwidth bottle neck

The experience Rehearses are essential before the real event. Can we use measure tools to make the life easier?

A proposal for DVTS-specific measurement tools

Design goals Test without the help of the counterpart Simulate the real DVTS behavior without using the DVTS system Built a common language between the application users and the network administrators Find the bottleneck of the network

The architecture Basic tool Access interface Dvmcast sender and reflector Dvping sender/receiver Access interface web Find the server alone the path AS path and DNS server Server registration Manual or automatic

The operation modes of basic tools dvmcast DVTS system DVTS file Sending mode Reflecting mode (1) Reflecting mode (2) dvping

The technical specification dvmcast and dvmping： -p snd_port (8000) -rp rcv_port (8000) -t period (sec) -bw bandwidth (bps/kbps/Mbps) host -4|6

Web interface
