The Impact of the Archipelago Measurement Platform

This page provides a compendium of data, datasets, publications and other impacts the Archipelago (Ark) measurement platform has made on the nascent science of Internet topology discovery, measurement, and analysis.

The Ark Measurement Infrastructure

As a measurement infrastructure, the Archipelago (Ark) platform has just begun to hit its stride on many fronts. With the adoption of the Raspberry Pi as a hardware platform, we have deployed 52 Pis since January 2013, a rate of nearly three monitors per month. We have implemented and deployed improvements in process automation, monitor management, and the underlying software that enables team communication and coordination (implemented as a distributed shared memory tuple space structure). This dedicated, reliable, and robust platform supports ongoing, scheduled, and ad-hoc experiments.

Research Enabled by Ark Data Products

Our web site lists publications known to us by non-CAIDA authors that make use of CAIDA data (summarized in Figure 1 below) [1], a lower bound since we cannot enforce the reporting requirements of our AUP. Researchers have requested CAIDA's topology data to support research in the areas of: modeling IPv4 and IPv6 AS-level topology and BGP behavior; alias resolution, router-level, and PoP-level topology discovery; improving any-cast implementations; new metrics for describing scale-free networks; peer-to-peer system scalability; improving visualization of complex systems; geolocation; modeling of delay; improved trace-back for network attacks; and improved packet marking/filtering. Publications reported back to us have covered a variety of topics related to the security and trustworthiness of the Internet as critical infrastructure [2, 3, 4]: risks of Internet partitioning [5]; prefix hijacking [6, 7, 8]; DDoS attack countermeasures [9, 10]; complex network robustness in the face of epidemics [11]; complex network theory [12, 13]; future Internet architectures; CDN architectures [14]; and a geographic database (Atlas) of the Internet [15].

CAIDA conducts twice per year searches to compile a list of papers that make use of CAIDA data. We currently find 70 papers making use of Ark data, 49 since 2011. We find 50% of papers used the IPv4 Routed /24 Topology Dataset , 25% used the IPv4 Routed /24 AS Links Dataset. We found 11 papers that make use of the Macroscopic Internet Topology Data Kit (ITDK). (CAIDA derives the data sets from the raw data gathered by Ark.)

Early in 2014, we loosened restrictions on topology data older than two years and now make it publicly downloadable. Users have downloaded 248.6 GiB of non-restricted Ark data since its release. Users have downloaded a total of 14.0 TiB of restricted Ark data since its inception in 2007.

Direct Use of Ark Infrastructure

In addition to access to the data collected by ongoing experiments running on the Ark infrastructure, we provide several methods of access for researchers to conduct their own coordinated measurements and experiments.

We provide this access primarily through the topo-on-demand (tod) service that provides a scriptable interface for performing IPv4 and IPv6 traceroutes and pings on Ark. It allows measurements from 100+ globally distributed monitors (36 with IPv6) in both commercial and R&E networks. The tod service supports varying levels of user sophistication and needs. A user accesses the service through remote client measurement requests via a single access point. Clients, whether web-based or command-line, can issue multiple concurrent requests and receive the results asynchronously.

There are two interfaces to tod, a command-line interface and a web-based interface. The command-line interface is useful for conducting large-scale feedback-driven, dynamic measurements under the full control of the user's own program (written in any language of the user's choosing, such as Perl, Python, Ruby, or C).

The web interface, Vela, provides an easy way for researchers to perform on-demand, ad-hoc exploratory topology measurements on Ark. Users can conduct ping and traceroute measurements in IPv4 and IPv6 using ICMP, UDP, or TCP from any Ark monitor. The Vela interface(s) are still in early days of development and beta testing. At this point, we have created accounts associated with one Regional Internet Registry, five accounts for government agencies (including the Naval Postgraduate School), nine accounts for academic researchers, and two accounts with commercial entities.

Approximately 20 hosting sites hold local shell accounts on the monitors.
