Modeling and performance analysis of IP access interface in optical packet switched networks

The article analyzes the influence of the IP access interface on the packet loss probability and delay times in the optical packet switched network. The network and node model have been proposed, and the assembler and hold features have been included in th ...

Measurement and Analysis of Single-Hop Delay on an IP Backbone Network

Patrick Thiran

We measure and analyze the single-hop packet delay through operational routers in the Sprint Internet protocol (IP) backbone network. After presenting our delay measurements through a single router for OC-3 and OC-12 link speeds, we propose a methodology t ...

Delay aspects in Internet telephony

Catherine Boutremans

In this work, we address the transport of high quality voice over the Internet with a particular concern for delays. Transport of interactive audio over IP networks often suffers from packet loss and variations in the network delay (jitter). Forward Error ...

Performance analysis of packet switched all-optical networks

All-optical packet switching has been intensively investigated in recent years as an alternative to static, crossconnect based networks. Several switch architectures have been proposed, all of them using buffers made of fibre delay lines. The paper address ...

Some properties of variable length packet shapers

Jean-Yves Le Boudec

The min-plus theory of greedy shapers has been developed after Cruz`s results on the calculus of network delays. An example of greedy shaper is the buffered leaky bucket controller. The theory of greedy shapers establishes a number of properties ...

Network Calculus

Jean-Yves Le Boudec, Patrick Thiran

Network Calculus is a collection of results based on Min-Plus algebra, which applies to deterministic queuing systems found in communication networks. It can be used for example to understand - the computations for delays used in the IETF guaranteed servic ...

Processing Transactions over Optimistic Atomic Broadcast Protocols

André Schiper, Fernando Pedone

Atomic broadcast primitives allow fault-tolerant cooperation between sites in adistributed system. Unfortunately, the delay incurred before a message can be delivered makes it difficult to implement high performance, scalable applications on top of atomic ...

The Alternative Best-Effort Service

Jean-Yves Le Boudec, Patrick Thiran, Paul Hurley

Alternative Best-Effort (ABE) is a novel service for IP networks which offers applications the choice between receiving a lower end-to-end delay and receiving more overall throughput. Every best effort packet is marked as either green or blue. Green packet ...

A Min-Plus System Theory for Constrained Traffic Regulation and Dynamic Service Guarantees

Jean-Yves Le Boudec, Patrick Thiran

By extending the system theory under the (min,+)-algebra to the time varying setting, we solve the problem of constrained traffic regulation and develop a calculus for dynamic service guarantees. For a constrained traffic regulation problem with maximum to ...
