There is a risk that network infrastructure market failures relating to electricity grids, carbon dioxide transport systems, passenger and freight transport systems, water delivery systems and urban planning could increase the costs of adjustment to climate change and mitigation. The proposed

Abstract — Data Link layer is considered as the weakest link in a secured network. If an initial attack comes in at Layer 2, the whole network can be compromised. To illustrate the weakness of Layer 2 networks, attacking tools for this layer are surveyed and discussed in this paper. The main

Metadata for the World Wide Web is important, but metadata for Peer-to-Peer (P2P) networks is absolutely crucial. In this paper we discuss the open source project Edutella which builds upon metadata standards defined for the WWW and aims to provide an RDFbased metadata infrastructure for P2P

to form networked virtual supercomputers or metacomputers. While the physical infrastructure to build such systems is becoming widespread, the heterogeneous and dynamic nature of the metacomputing environment poses new challenges for developers of system software, parallel tools, and applications

Abstract—We present the first practical example of an entirely new class of network attacks – attacks that target the network in-frastructure. Modern routers in computer networks use general-purpose programmable packet processors. The software used for packet processing on these systems

infrastructures, particularly the Internet. Specifically, we revisit the notion of “organized complexity ” and suggest that it is fundamental to our ability to understand, operate, and design next-generation infrastructure networks. We comment on the role of engineering in defining an architecture to support

with distinct security requirements. We propose a solution to one, the managed-open scenario where no network infrastructure is pre-deployed, but a small amount of prior security coordination is expected. Our protocol, ARAN, is based on certificates and successfully defeats all identified attacks.

, unblocked websites into proxies, without their explicit collaboration. We envision that friendly ISPs would deploy Telex stations on paths between censors’ networks and popular, uncensored Internet destinations. Telex stations would monitor seemingly innocuous flows for a special “tag ” and transparently

In today’s chaotic network, data and services are mobile and replicated widely for availability, durability, and locality. Components within this infrastructure interact in rich and complex ways, greatly stressing traditional approaches to name service and routing. This paper explores

This paper presents Scribe, a scalable application-level multicast infrastructure. Scribe supports large numbers of groups, with a potentially large number of members per group. Scribe is built on top of Pastry, a generic peer-to-peer object location and routing substrate overlayed on the Internet
