  • Real-time BGP Monitoring

    Radar by Qrator is a BGP monitoring service that allows you to detect network anomalies that can significantly impact the availability and quality of services at the global routing level.
    The solution is built upon a proprietary path collector and unique algorithms for detecting BGP incidents, such as Route Leaks, Hijacks, Bogons in real-time.

  • Radar Monitor

    Radar by Qrator presents analytical data about autonomous systems (AS). The platform allows the detection of a wide range of network anomalies, which may significantly impact the endpoint network resource availability.
    Information Qrator.Radar provides about connectivity for the given AS is based on the proprietary AS Relationship model. Currently our system detects not only different BGP Incidents, but additionally general network anomalies like Routing Loops, DDoS Amplifiers, Vulnerable Ports.

    This information is updated daily free of charge.

  • AS Rating

    In order to simplify the process of comparing different AS our portal provides a set of ratings which let the user perform comparisons by various parameters. For user convenience we have added the search function which makes evaluation of a certain AS in the list a lot easier.

BGP Route Leak prevention and detection with the help of the RFC9234

All the credit is due to the RFC’s authors: A. Azimov (Qrator Labs & Yandex), E. Bogomazov (Qrator Labs), R. Bush (IIJ & Arrcus), K. Patel (Arrcus), K. Sriram.

A BGP route leak is an unintentional propagation of BGP prefixes beyond the intended scope that could result in a redirection of traffic through an unintended path that may enable eavesdropping or traffic analysis, and may or may not result in an overload or complete drop (black hole) of the traffic. Route leaks can be accidental or malicious but most often arise from accidental misconfigurations.

The 2022 National Internet Segment Reliability Research

The National Internet Segment Reliability Research explains how the outage of a single Autonomous System might affect the connectivity of the impacted region with the rest of the world. Generally, the most critical AS in the region is the dominant ISP on the market, but not always.

As the number of alternate routes between ASes increases (the "Internet" stands for "interconnected networks" - and each network is an AS), so does the fault-tolerance and stability of the Internet across the globe. Although some paths are more important than others from the beginning, establishing as many alternate routes as possible is the only viable way to ensure an adequately robust network.

The global connectivity of any given AS, whether an international giant or a regional player, depends on the quantity and quality of its path to Tier-1 ISPs.

Usually, Tier-1 implies an international company offering global IP transit service over connections with other Tier-1 providers. Nevertheless, there is no guarantee that such connectivity will always be maintained. For many ISPs at all "tiers", losing connection to even one Tier-1 peer would likely render them unreachable from some parts of the world.
