We consider the problem of video multicast over networks that enforce fair bandwidth allocations in the routers. State-of-the-art layered IP multicast systems perform well for moderately sized sessions, but suffer from three basic problems that prevent the ...
A fair exchange protocol is a protocol, in which two (or more) mutually suspicious parties exchange their digital items in a way that neither party can gain an advantage over the other by misbehaving. Many fair exchange protocols have been proposed in the ...

A new multiplexing schedule is derived for multiplexing holograms in photorefractive polymers which do not exhibit mono-exponential recording behavior. An M-number (M/#) of 0.3 was measured experimentally by recording 20 holograms of roughly equal strength ...
In this work, we define a novel Internet service, called ABE (Alternative Best-Effort), which allows interactive multimedia applications to receive low queuing delay within the existing best-effort Internet. We then develop and analyse a number of innovati ...
We present a novel scheduling algorithm, Duplicate Scheduling with Deadlines (DSD). This algorithm implements the ABE service which allows interactive, adaptive applications, that mark their packets green, to receive a low bounded delay at the expense of m ...

We study a methodology for constructing scheduled systems by restricting successively the behavior of the processes to be scheduled. Restriction is used to guarantee the satisfaction of two types of constraints: schedulability constraints characterizing ti ...
We consider a network implementing scheduling per aggregate flow. We show that the derivation of bounds that was published in [1] is false. We give a worst case bound which is valid for any network topology, given the maximum hop count for every flow and t ...
It is well known that a simple binary feedback rate--based congestion avoidance scheme cannot ensure a fairness goal of the Available Bit Rate (ABR) service, namely, max--min fairness. In this paper we show how the rates are distributed for the network con ...
