Failure Location in WDM Networks

Patrick Thiran, Xuan Hung Nguyen, Carmen Mas

Fault identification and location in optical networks must cope with a multitude of factors: (i) the redundancy and the lack of coordination (internetworking) of the managements at the different layers (WDM, SDH/SONET, ATM, IP) ...

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 ...

End-to-end congestion control for tcp-friendly flows with variable packet size

Jean-Yves Le Boudec, Jörg Widmer, Catherine Boutremans

Current TCP-friendly congestion control mechanisms adjust the packet rate in order to adapt to network conditions and obtain a throughput not exceeding that of a TCP connection operating under the same conditions. In an environment where the bottleneck res ...

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 ...

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 ...

End-to-end Congestion Control for Flows with Variable Packet Size

Jean-Yves Le Boudec, Jörg Widmer, Catherine Boutremans

Current TCP-friendly congestion control mechanisms such as those used in TFRC adjust the packet rate in order to adapt to network conditions and obtain a throughput not exceeding that of a TCP connection operating under the same conditions. In an environme ...

Method and System for Processing Data Packets

The present invention provides an improved method and a system for processing data packets in a router. The router includes a plurality of input/output ports and more than one packet processing units. The packet processing units derive from a piece of info ...

An efficient algorithm for locating soft and hard failures in WDM networks

Patrick Thiran, Carmen Mas

Fault identification and location in optical networks is hampered by a multitude of factors: (i) the redundancy and the lack of coordination (internetworking) of the managements at the different layers (WDM, SDH/SONET, ATM, IP) ...

Circuit Emulation over IP Networks

Jean-Pierre Hubaux

Recent developments in transmission and switching technology has made available low-cost gigabit network capacity forpacket-based WANs (e.g., IP over WDM), that will not require the intermediate SONET/SDH multiplexing layer. For competitive operators that ...

Designing new network adaptation and ATM adaptation layers for interactive multimedia applications

Multimedia services, audiovisual applications composed of a combination of discrete and continuous data streams, will be a major part of the traffic flowing in the next generation of high speed networks. The cornerstones for multimedia are Asynchronous Tra ...
