Bandwidth sharing networks with priority scaling
Abstract: In multi-class communication networks, traffic surges due to one class of users can significantly degrade the performance for other classes. During these transient periods, it is thus of crucial importance to implement priority mechanisms that conserve the quality of service experienced by the affected classes, while ensuring that the temporarily unstable class is not entirely neglect...
متن کاملBandwidth-sharing networks in overload
In the present talk we focus on α-fair bandwidth-sharing networks where the load on one or several of the links exceeds the capacity. In order to characterize the overload behavior, we examine the fluid limit, which emerges from a suitably scaled version of the number of flows of the various classes. We prove that the fluid limit is a linear function of time, and derive a fixed-point equation f...
متن کاملInsensitive Bandwidth Sharing in Data Networks
We represent a data network as a set of links shared by a dynamic number of competing flows. These flows are generated within sessions and correspond to the transfer of a random volume of data on a pre-defined network route. The evolution of the stochastic process describing the number of flows on all routes, which determines the performance of the data transfers, depends on how link capacity i...
متن کاملA stability conjecture on bandwidth sharing networks
We consider a queueing model where documents are simultaneously transferred over a communication network. The bandwidth allocated to each document transfer is assumed to be the solution of a utility optimization problem. Under a natural stability condition and under the assumption that document arrivals are Poisson and that document sizes are independent exponential distributions, such queueing...
متن کاملBandwidth-sharing networks under a diffusion scaling
This paper considers networks operating under α-fair bandwidth sharing. When imposing a peak rate (i.e., an upper bound on the users' transmission rates, which could be thought of as access rates), the equilibrium point of the uid limit is explicitly identi ed, for both the single-node network as well as the linear network. More speci cally, a criterion is derived that indicates, for each speci...
