Recording of measurements exceeding nominal speed

The check of speed results on HYPERION has been changed, in order to allow recording of measurements exceeding the nominal speed of a subscription package.

This check had been incorporated in the system design, in order to prevent mistakes of users in declaring their nominal speeds. However, many ISPs in Greece currently allow measurements higher than the nominal speed; as a result, these measurements did not get recorded and the users received an error message.

The system now allows a specific deviation from the nominal speed for each packet (both in the downlink and the uplink), based on data provided by the ISPs.

We emphasize the need for users to correctly declare their nominal speeds in their account settings, in order to avoid mistakes in the presentation of individual measurements on the map and the production of statistics. Users can make corrections by logging into their account, clicking on “Settings”, selecting the correct package from the list and clicking “Update account”

Addition of “registered providers” section

A new section has been added to the Hyperion platform, entitled: “Registered providers”. It includes a list of the providers registered in the platform, their nominal speeds and access technologies, as well as registration instructions for new providers.

Upgrade to M-Lab 2.0

A significant upgrade of the M-Lab platform was recently finished, including an update of the NDT (Network Diagnostic Tool) used in Hyperion measurements.
The upgrade included a list of changes, such as the transition from Web100 to TCP_INFO for TCP instrumentation, the change from TCP Reno to TCP Cubic Congestion Control, as well as changes to some NDT parameters (most importantly, the latency shown now in the NDT results is the minimum RTT value of the packets sent during the measurement, instead of the average RTT value). More information about the upgrade is available at a relevant M-Lab post: https://www.measurementlab.net/blog/the-platform-has-landed/.

Following the changes in NDT parameters, a significant malfunction appeared in Hyperion from the start of November 2019 until mid-January 2020. As a result of this malfunction, many user measurements could not be concluded, or some of the measurement parameters were not recorded. We apologize to the Hyperion users for the inconvenience that this has caused.

Changes to the “HYPERION” public statistics

As part of the upgrade of the broadband measurement platform HYPERION (https://hyperiontest.gr/), the general statistics provided to the public have been improved. From now on, website visitors have the possibility to see the number of measurements from registered Hyperion users, per ISP and geographical area (region, regional unit) for any time interval, as well as download the results in csv format. The public statistics are available at: https://hyperiontest.gr/?l=1&action=stats.

It is reminded that EETT also provides all measurement results as open data on the Hyperion website (https://hyperiontest.gr/?l=1&action=opendata).

HYPERION equipment upgrade at GR-IX

In cooperation with M-Lab (Measurement Lab), EETT recently performed a significant upgrade of Hyperion equipment at the GR-IX (Greek Internet Exchange). All measurement servers (3 production server and 1 test server) have been replaced with new ones, as well as the optical switch connecting to the GR-IX, increasing the interconnection capacity from 1 to 10 Gbps.

The performed upgrade allows the Hyperion platform (https://hyperiontest.gr/) to conform to the modern requirements of broadband measurement systems, ensuring the existence of sufficient capacity and availability at the measurement servers.

Through the Hyperion platform, end-users can assess the performance of their broadband connection (speed, delay, delay variation, packet loss rate) and contribute to the supervision of broadband connection quality by EETT.

Addition of HCN to HYPERION

Hellenic Cable Networks (HCN) has been added to the HYPERION database. The company offers Internet access services through cable and fiber networks.

Subscribers of this company may now register to HYPERION and measure the performance of their Internet connection as registered users.

Until now, the following ISPs have been registered to the HYPERION database:

• Cyta
• Diodos (GRNET academic community service)
• Forthnet (Nova)
• HCN
• INALAN
• OTE
• Vodafone
• Wind

It is reminded that every fixed ISP in Greece may provide their network and nominal speed information to EETT, so that they can be added to the HYPERION database. Contact email: hyperiontest@eett.gr

Changes to the broadband measurement platform “HYPERION”

As part of the upgrade of the broadband measurement platform HYPERION, the following changes have been implemented since 2-16-2018:

• Migration of the site to HTTPS, for increased security during browsing and user entry of information
• Publication of open data from measurements of registered and anonymous users: EETT provides all measurement data from HYPERION to the public for free. The provided data include measurements from both registered and anonymous users, and have been adequately processed so as not to contain any personal information (user IP address and location information). The user can select the time period of interest and download the data in CSV format. The data are encoded in UTF-8 format and also contain greek characters. They can be freely reused by any interested party (e.g. ISPs, researchers, or even simple users).
• Mapping of measurements to the new administrative units of Greece: Kallikratis Municipality, Regional Unit, Region: Location information on measurements of registered users has been mapped to four different layers: postal code, Kallikratis Municipality, Regional Unit, Region.

Corresponding updates have been made to the website texts and the user manual.

EETT will continue its effort to further upgrade the HYPERION platform and provide users with a useful tool to monitor the quality of their broadband connection.
