MPLS Protection Switching Vs. OSPF Rerouting: A Simulative Comparison

Resilience is becoming a key design issue for future IP-based networks having a growing commercial importance. In the case of element failures the networks have to reconfigure in the order of a few hundred milliseconds, i.e. much faster than provided by the slow rerouting of current implementations. Several multi-path extensions...

Scalability of Network-Failure Resilience

This work quantifies scalability of network resilience upon failures. It characterize resilience as the percentage of lost traffic upon failures and define scalability as the growth rate of the percentage of lost traffic with respect to network size, link failure probability and traffic for given failure protection schemes. Probabilistic graphical...

Increase Network Security and Resilience With Network Admission Control

Until now authenticating the security profile of a user's endpoint device on a network has been virtually impossible. This security weak point has meant that even the most trustworthy user could inadvertently expose everyone else on the network to damaging and costly risks with a single noncompliant device. Network Admission...

Improving the Fault Resilience of Overlay Multicast for Media Streaming

This paper addresses the problem of fault resilience of overlay-based live media streaming from two aspects: how to construct a stable multicast tree that minimizes the negative impact of frequent member departures on existing overlay, and how to efficiently recover from packet errors caused by end-system or network failures. In...

Incentive, Resilience and Load Balancing in Multicasting Through Clustered de Bruijn Overlay Network

This paper considers the problem of multicasting a stream of packets in a large scale peer-to-peer environment. In that context peers should have incentive to cooperate. It presents PrefixStream, an algorithm that addresses this problem by using reciprocity in packet forwarding. Each node thus has incentive to forward since recipients...

Ripple-Stream: Safeguarding P2P Streaming Against DoS Attacks

Compared with file-sharing and Distributed Hash Table DHT network, P2P video streaming is more vulnerable to Denial of Service DoS attacks because of its high bandwidth demand and stringent time requirement. This paper studies the design of DoS resilient streaming networks using credit systems. This paper proposes a novel framework...
