We consider the definition of the Expedited Forwarding Per-Hop Behaviour (EF PHB) as given in RFC 2598\ \cite{rfc2598}, and its impact on worst case end-to-end delay jitter. On one hand, the definition in RFC 2598 can be used to predict extremely low end-t ...
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 consider a FIFO multiplexer fed by flows that are individually constrained by arrival curves, and look for the best possible arrival curve for every output flow. This problem arises in scenarios where aggregate multiplexing is performed, such as differe ...
Packet Scale Rate Guarantee (PSRG) is a node model used by IETF for Expedited Forwarding, a priority service defined in the context of Differentiated Services. We review probabilistic performance bounds that apply to PSRG nodes, and improve a previous boun ...

We consider the transmission of variable bit rate video over a network offering a guaranteed service such as ATM VBR or the guaranteed service of the IETF. The guaranteed service requires that the flow accepted by the network has to be conforming with a tr ...

Packet Scale Rate Guarantee (PSRG) is a generic node model which underlies the definition of Expedited Forwarding (EF) proposed in the context of Internet Differentiated Services. For the case of FIFO nodes, PSRG is equivalent to the well-understood concep ...

Personal computing and communication devices such as computers, personal digital assistants (PDAs), and mobile phones are moving to their next generation in which the end user will be able to access a multitude of information with a single device either lo ...
