Abstract

Offline scheduling is attractive when the traffic profile is known a priori since the complexity of online scheduling is largely removed. Given any admissible rate matrix @L=(@l"i"j), Birkhoff-von Neumann decomposition offers a quasi-offline scheduling strategy that can provide a service rate of at least @l"i"j for each flow (i,j) without internal speedup. This paper extends the Birkhoff-von Neumann switching strategy to consider traffic profiles in which the traffic demands are specified as statistical distributions rather than fixed rates.
