Global Networks for High Energy Physics, Research and Education in the LHC Era

Speaker: Harvey Newman, Caltech
Location: Annenberg 105
Wide area networks of global reach and rapidly increasing capacity and capability, have been a key 
to major scientific breakthroughs, including the discovery of the Higgs boson in July 2012. As we pass 
from network generation to generation, the bandwidth needs of the scientific community have grown 
by more than two orders of magnitude in the last decade, keeping pace with the exponential growth of 
major continental and transoceanic network infrastructures serving research and education. With the 
opening of the Large Hadron Collider era the outlook is for similar growth, and the development of more 
pervasive intelligent network systems to access and distribute 1 to 100 Petabyte-scale datasets, supporting 
the work of thousands of physicists and students in all corners of the globe as they search for the next 
round of discoveries. Physicists working with network engineers and computer scientists have learned 
to use networks effectively in the 10 Gigabit/sec and more recently the 100 Gigabit/sec range, and have 
developed new data transfer methods and architectures, and the ability to allocate and schedule bandwidth 
channels dynamically, placing them among the leading developers of global networks. I will review the 
LHC experiments' changing Computing Models, the growth and qualitative changes in network needs, 
and similar trends in other fields of "data intensive science". I will give an update on the status and outlook 
for the world's research networks, technology advances focused on the transition to the next generation of 
network circuits and emerging modes of data transmission, and I will touch on the problem of the Digital
Divide, based on the recent work of ICFA's Standing Committee on Inter-regional Connectivity (SCIC).
