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 Λ = ( λ ij ) , Birkhoff-von Neumann decomposition offers a quasi-offline scheduling strategy that can provide a service rate of at least λ ij 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.
