On Survivable Routing of Mesh Topologies in IP-over-WDM Networks

Patrick Thiran, Maciej Kurant

Failure restoration at the IP layer in IP-over-WDM networks requires to map the IP topology on the WDM topology in such a way that a failure at the WDM layer leaves the IP topology connected. Such a mapping is called survivable. Finding a survivable mappin ...

Binary Versus Analogue Path Monitoring in IP Networks

Patrick Thiran, Xuan Hung Nguyen

Monitoring systems that can detect path outages and periods of degraded performance are important for many distributed applications. Trivial pairwise probing systems do not scale well and cannot be employed in large networks. To build scalable path monitor ...

Communication Infrastructure Design for Wide-Area Mobile Computation: Specification in Nomadic Pict

We review an example of wide-area mobile agent applications: video-on-demand, long-lived scientific computation, and collaborative work, and the design of a distributed infrastructure required in each of these applications for location-independent communic ...

A multiple core mode for protocol independent multicast

Francesc Font Torre de Mer

Internet communications have traditionally been based on point-to-point connections. This technique is called unicast and allows one sender and one receiver to communicate. The Internet saw the appearance of multicast protocols in the early 90's. Multicast ...

Optimistic atomic broadcast: a pragmatic viewpoint F.Pedone and A.Schiper This paper presents the Optimistic Atomic Broadcast algorithm (OPT-ABcast) which exploits the spontaneous total-order property experienced in local-area networks in order to allow fa ...

We consider the problem of distributing high-quality video signals over IP multicast in large Local Area Networks (LANs), under real-time delay constraints, and with software-only processing. In a large LAN (such as the network of a university campus, or t ...

Ruminations on Domain-Based Reliable Broadcast

Fernando Pedone

A distributed system is no longer confined to a single administrative domain. Peer-to-peer applications and business-to-business e-commerce systems, for example, typically span multiple local-area and wide-area networks, raising issues of trust, security, ...

Broadcast quality video over IP

We consider the problem of designing systems for the transmission of high-quality video signals over certain high-speed segments of the public IP network. Our most important contribution is the definition of a network/coder interface for IP networks which ...

We propose Alternative Best-Effort (ABE), a novel service for IP networks, which relies on the idea of providing low-delay at the expense of maybe less throughput. The objective is to retain the simplicity of the original Internet single class, best effort ...

In this paper we simulated terminode routing. This routing scheme is designed for wide area networks, where a large part or all the nodes are mobile. Terminode routing is a combination of two protocols called Terminode Local Routing (TLR) and Terminode Rem ...
