SUMMARY:Revisiting delay-based TCP\, and implementing  'stateless' TCP for
  HTTP servers - Grenville Armitage (Swinburne University of Technology)

DESCRIPTION:This talk will cover two papers being presented at IFIP Networ
 king 2011 [1] and NOSSDAV 2011 [2] respectively. The first looks at a nove
 l variant of TCP that uses the gradient of RTT fluctuations to infer when 
 losses are congestion-induced or not\, and minimises induced queuing delay
 s relative to loss-based TCP. The second looks at some simplifications ('h
 acks') to the TCP state machine that significantly reduces the resource re
 quirements of HTTP servers.\n\nBio: Grenville Armitage is a Professor of T
 elecommunications Engineering at Swinburne University of Technology\, Melb
 ourne\, Australia. He is also Director of the Centre for Advanced Internet
  Architectures\, a small research group at the University. He was active i
 n industry R&D and the IETF in the 1990s\, and active in academia during t
 he past decade. His interests tend to revolve around anything to do with I
 P network infrastructure (such as performance\, scalability\, resilience a
 nd monitoring) that ultimately impacts on an end-user's experience of 'the
  internet'. More at <http://caia.swin.edu.au/cv/garmitage/> http://caia.sw
