[Nets-seminars] Talk tomorrow Fri 7th October, GS/302, 16:30 pm (NOTE LATE START)

[Richard G. Clegg]

Tomorrow's talk will be given be João Araújo.  The title is:

Balancing by PREFLEX: Congestion Aware Traffic Engineering

Despite the Internet becoming more interconnected, networks are severely 
limited in their ability to balance traffic and take advantage of this 
path diversity. These limitations stem in part due to the single 
forwarding path nature of existing routing protocols, but are further 
exacerbated by the inability of networks to assess the impact of their 
routing choices on end-to-end performance.

This talk will present PREFLEX, an adaptive, end-to-end traffic 
balancing architecture which uses end-host information to balance 
congestion, rather than load.
It is unique in that it requires no network per-flow state, induces no 
packet reordering and operates on far shorter timescales than current 
traffic engineering methods,
providing the necessary framework to meet the increasing demands of 
users while simultaneously offering edge networks more fine-grained 
control over traffic.
We will also describe a method of automatically adjusting how PREFLEX 
will split traffic in order to balance loss across multiple paths in a 
variety of network conditions.
Additionally, preliminary measurement data will be shown to exemplify 
some of the detrimental effects of current interdomain routing on 
end-to-end performance.
