software development. I worked at Bell, Teleglobe, Intelsat, CBC and as a

expert consultant.

Professional Engineer, Masters in Technological Management, ITIL

foundation, PMP

I have extensive experience in speaking since the 90's (ouf!), subjects were

always a mix of technologies, commerce and management.

Past engagements included: Service Oriented Architecture: Tutorial for the

Broadcasters (2010), Pitfalls of SW development: What every executive should

know (2009), 8 weeks on Twitter: I love it! (2009), The Future of Broadcast

Archive Systems (2008), DVB-H: Video over IP goes Wireless (2006), HDTV

distribution (2005), Video over IP (2004) and, Several broadcast technical

training (1994-1998): Video 101, Digital Video and Compression 201, Video

SO… WHAT’S NEW?Ready to stretch a little bit?

UDP-BASED DATA TRANSFER (UDT)

Created in 2001

Current version #4 released in 2007

IETF Candidate draft-gg-udt-03 (April 12th 2010)

Very high speed network (above DS3) – WAN

File transfer of very large files (above 1TB) over long distances

Unicast, duplex, connection-based

Client-server or Rendezvous (P2P)

Muxing

Periodic ACK, relative to time and not traffic

Congestion control (configurable, default = AIMD)

Reliability mechanisms

@ 155mbps, 50msec, 2x better than TCP

@ 1Gbps, 25msec delay, 4x better than TCP21
