Summary

Title: Isolario: the real-time Internet routing observatory (by Alessandro Improta) Abstract: The incompleteness of data collected from BGP route collecting projects is a well-known issue. Recent works explained that one of the possible solution is to increase the contribution in terms of routing data collected from ASes located in the Internet periphery, in order to reveal the peering connectivity of their upstream providers. IIT-CNR developed the Isolario project to fill this gap. Isolario is a BGP route collecting project based on the do-ut-des principle which aims to increase the appeal of route collecting by offering services in return, ranging from real-time analyses of the incoming BGP session(s) to historic analyses of routing reachability. This presentation will introduce the basic elements of Isolario and the rationale lying behind the project, with a fast overview about its services, the solutions applied and future works.

Title: ICE: A memory-efficient BGP route collecting engine (by Luca Sani) Abstract: ICE is a multi-threaded and memory-efficient BGP collecting engine which allows route collectors to efficiently handle real-time queries of the routing table. ICE is designed to allow concurrent read/write operations on the routing table. Memory efficiency has been obtained thanks to the design of a variant of the Liv-Zempel compression algorithms specifically tailored to operate within a BGP real-time collecting environment. The proposed technique exploits the high degree of repetitiveness characterizing BGP data and reduces the ICE memory usage by as much as 30%. ICE is currently used as the route collecting software in the Isolario project.

Title: BGP Scanner: C library & tool (by Lorenzo Cogotti) Abstract: During the last years the amount of data collected has increased greatly, mostly due to the introduction of new route collectors (e.g. PCH, Isolario), new BGP feeders, new BGP extensions (e.g. Multiprotocol RFC4760, ADDPATH RFC7911) and, of course, due to the natural growth of the Internet. Most of the available MRT-BGP data reader available were designed when the amount of data available was smaller, and as a consequence are not able to perform efficiently with current datasets. Moreover most of them do not support most of the BGP extensions introduced in time usually because they are not properly maintained and updated. In this presentation is presented BGP scanner, a new open source MRT-BGP data reader and C library implemented at IIT-CNR, which is exploited in Isolario project. To the best of our knowledge, BGP scanner outperforms all the MRT-BGP data reader freely available online, in terms of speed and memory consumption.
