Title: Distributed Rate Limiting
Time: Tuesday April 3rd, 2012 @ 4:00 – 5:00 PM, followed by a Q&A and refreshments
Location: Building 356, Room 109
Speaker: Richard Ramsden (4th CSCI Student, Vancouver Island University)

Abstract:

The Distributed Rate Limiting (DRL) problem can be described as trying to distribute service capacity (“service rate”), expressed as a number of service requests per time interval, over a group of N servers in such a way that the amount given to each server C_i is dependent on the job population D_i at each server.  We want to find a fair distribution of the service rate such that (D_i / C_i) is equal at every server. Creating a distributed algorithm to solve this problem is non-trivial since demand at each server is dynamic, i.e., changes with time. Furthermore, servers can fail for numerous reasons.  Designing an algorithm which adapts quickly to change and is fault-tolerant is the main contribution of my research.
