Simulating convergence properties of BGP
We present a simple BGP simulator that is used for testing convergence properties of inter-domain routing. The discrete-event driven simulator contains a high-level abstraction model of the BGP protocol. The purpose is to perform simulations to examine the complexity of routing information exchange and to test different possible reasons for delayed convergence of BGP routing. We have simulated ...
متن کاملAn Experimental Analysis of BGP Convergence Time
The Border Gateway Protocol (BGP) is the routing protocol used to maintain connectivity between autonomous systems in the Internet. Empirical measurements have shown that there can be considerable delay in BGP convergence after routing changes. One contributing factor in this delay is a BGP-specific timer used to limit the rate at which routing messages are transmitted. We use the SSFNet simula...
متن کاملan infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولSensibility analysis of BGP convergence and scalability using network simulation
The Border Gateway Protocol (BGP) is the quasi-standard for the routing between autonomous systems in the Internet. Instabilities in the topology like a failing link can lead to a considerable delay in convergence times. Therefore it is necessary to gain a better understanding of the global dynamics and underlying mechanisms of BGP. In this work we perform a sensibility analysis of convergence ...
متن کاملBGP-RCN: improving BGP convergence through root cause notification
This paper presents a new mechanism, called BGP with root cause notification (BGP-RCN), that provides an upper bound of O(d) on routing convergence delay for BGP, where d is the network diameter as measured by the number of AS hops. BGP-RCN lets each routing update message carry the information about the specific cause which triggered the update message. Once a node v receives the first update ...
