About

NLnet Labs is a research and development group that focuses on those developments in Internet technology where bridges between theory and practical deployment need to be built; areas where engineering and standardization takes place.
It is our goal to play an active and relevant role in these areas through the development of open source software, through participating in development of open standards, and through the dissemination of knowledge.
All our deliverables are targeted to enhance the open, secure, and innovative nature of the Internet for all. » Read more.

Multi-Path Inter-Domain Routing: The Impact on BGP's Scalability, Stability, and Resilience to Link Failures

Wed, 31 Aug 2011
Multi-path routing protocols are proposed to solve transient disconnectivity during convergence time. As their name implies, these protocols are designed to explore more paths than BGP in the attempt to keep the ASes connected in case of link failures. The impact of the multi-path routing protocols on scalability, stability, and resilience to link failures are studied using simulation experiments.
