Watching Data Streams Toward a Multi-Homed Sink Under Routing Changes Introduced by a BGP Beacon
نویسندگان
چکیده
Certain popular metrics have been used to reflect the instability of the Internet control plane, such as the volume and duration of BGP updates. However, it is unclear whether there is a direct relationship between those metrics and the data plane performance, especially as the Internet is becoming more densely connected and many networks become multi-homed. To clarify this, we measured data streams from a number of PlanetLab nodes toward a sink behind a multi-homed BGP Beacon, which can introduce scheduled BGP routing changes to potentially affect the performance of those data streams. In particular, as an important first step, we measured the delay, drop, jitter, and reordering of these data streams and compare them against the volume and duration of BGP updates. We found these data streams were only slightly affected and there is little correlations between these selected metrics from the two planes. Further work includes the correlation of the data plane performance with other control plane metrics while considering more types of routing changes.

Hot Potatoes Heat Up BGP Routing
The separation of intradomain and interdomain routing is a key feature of the Internet routing architecture. However, intradomain routing protocols such as OSPF and IS-IS do have a (sometimes significant) influence on the path-selection process in Border Gateway Protocol (BGP). In this paper, we argue that researchers should revisit the “interface” between the two tiers of the Internet routing ...
متن کاملTowards Self-Adaptive Inter-Domain Edge Routing
At present, greedily managing inter-domain traffic at the edge of the network is becoming a common practice. However, the stability implications of these practices under massive utilization are completely unknown. Given that global stability is a must for the current and future Internet, self-adapting mechanisms will be necessary if masses of absolutely independent and uncoordinated multi-homed...
متن کاملInferring Major Events from BGP Update Streams
BGP updates are triggered by a variety of events such as link failures, session resets, router crashes, policy or configuration changes. Making sense of BGP update streams and inferring their underlying causes is important in trouble-shooting BGP and improving its performance. In this paper we propose a novel methodology to identify BGP updates associated with major events– affecting network re...
متن کاملMulti-domain optical routing: Is there life beyond extending BGP?
The design of new inter-domain optical routing protocols may start from scratch, or on the contrary exploit all the research already developed in IP networks with the Border Gateway Protocol (BGP). Even though the network premises under which BGP was conceived have drastically changed, the pervasive deployment of BGP makes almost impossible its replacement, hence everything indicates that BGP-b...
متن کاملManaging BGP Routes with a BGP Session Multiplexer
This paper presents the design, implementation, and evaluation of BGP-Mux, a system for providing multiple clients access to a common set of BGP update streams from multiple BGP peers. By providing multiple clients access to the same set of BGP feeds, BGP-Mux facilitates many applications, including: (1) scalable, real-time monitoring of BGP update feeds; (3) new routing architectures that requ...
