iThena.Measurements is a volunteer distributed computing project based on the BOINC platform. The project is part of the broader iThena initiative, which focuses on experimental mapping and analysis of the global Internet infrastructure through distributed measurements performed by volunteer computers.[1]
The project performs large-scale Internet measurements including latency testing, bandwidth analysis, packet routing studies, and traceroute-based topology discovery. Data gathered by volunteers is used to model Internet network structures at multiple levels including routers, points of presence (PoPs), and autonomous systems (ASes).[2]
History
The first test activities related to the iThena project began on 29 August 2019.[2] Public announcements regarding the project appeared in September 2019 as the developers prepared BOINC applications for distributed Internet measurements.[3]
The project was divided into two major components:
- iThena.Measurements — the measurement subsystem performing distributed network diagnostics and Internet mapping.
- iThena.Computational — a computational subsystem responsible for post-processing and graph analysis of collected measurement data.[1]
The project experienced several periods of instability and intermittent downtime during its operation, including SSL certificate issues and server outages discussed by BOINC community members on the official BOINC forums.[4]
Why iThena.Measurements?
Modern Internet infrastructure is extremely complex and constantly changing. Large-scale mapping of routing paths, latency characteristics, and bandwidth relationships requires measurements from geographically distributed systems. Traditional centralized measurement systems are limited in scope and perspective.
iThena.Measurements attempts to solve this problem using volunteer computing. By distributing lightweight network-measurement applications to thousands of volunteer computers around the world, the project can gather data from many regions and Internet providers simultaneously.[1]
The collected information can help researchers better understand:
- Internet topology
- Routing efficiency
- Packet loss patterns
- Network latency
- Bandwidth limitations
- Connectivity between autonomous systems

Goal
The primary objective of iThena.Measurements is to build realistic models of the global Internet infrastructure using data gathered from distributed volunteer hosts.[2]
The project aims to:
- Perform large-scale network measurements
- Analyze Internet routing structures
- Create topology maps of Internet infrastructure
- Study latency and packet-loss relationships
- Measure network bandwidth between distributed endpoints
- Provide datasets for later computational graph analysis
According to the project developers, the resulting datasets may be used for future research into Internet structure visualization and analysis.[1]
Methods

iThena.Measurements uses the BOINC middleware platform to distribute measurement tasks to volunteer computers around the world.[5]
The project currently includes several applications:
CNode
The iThena CNode application performs sequences of traceroute procedures from volunteer computers. The resulting routing information is returned to the project servers and incorporated into the central database for further analysis.[1]
PERF
The iThena PERF application performs bandwidth testing and network performance analysis between volunteer systems and designated endpoints.[1]
OONI Probe
The project also distributed an OONI Probe wrapper application intended for Internet measurement and network-observability tasks.[1]
Why BOINC?
The project relies on BOINC because distributed volunteer computing enables measurements from a very large number of geographically dispersed systems. Unlike centralized measurement servers, BOINC volunteers provide many independent network vantage points, allowing broader Internet visibility and more realistic network mapping.[6]
The BOINC infrastructure also provides:
- Cross-platform application distribution
- Secure task validation
- Volunteer account management
- Credit and statistics systems
- Scalable task scheduling

Applications
| Application | Purpose | Platform support |
|---|---|---|
| CNode | Traceroute and routing analysis | Linux, Windows |
| PERF | Bandwidth and performance testing | Linux, Windows |
| OONI Probe | Internet observability measurements | Primarily Linux |
Platform support
The project primarily supports Linux systems, especially x86_64 Linux platforms. Some applications are also available for Microsoft Windows.[1]
According to the project website, some applications are distributed as beta applications and require volunteers to enable test applications in their BOINC preferences.[7]
Statistics
As of March 2026, the project reported:
- More than 521,000 registered users
- More than 134,000 hosts
- Participation from over 14,000 teams[7]
The largest contributor countries by total credit included Ukraine, the United States, Japan, and Germany.[7]
Project team / Sponsors
The project administrator and lead developer is Łukasz Świerczewski.[1]
The project appears to operate independently without a major institutional sponsor publicly listed on the project website.
Scientific results
The project has primarily focused on infrastructure development and collection of Internet measurement datasets. Publicly available scientific publications directly associated with iThena.Measurements remain limited as of 2026.
The broader iThena initiative has emphasized future graph-analysis and network-modeling work using datasets gathered by the measurement subsystem.[1]
Community and reception
The project attracted interest within the BOINC community because of its focus on Internet topology and network measurement rather than traditional scientific simulations.[8]
Community discussions also noted periods of instability, intermittent outages, and maintenance interruptions throughout the project's operation.[9]
