Number of Russian edge AS containing IP of web nodes
Number of routes in Full View to these AS
Number of routes from MSK-IX and DATAIX route servers to these AS
Web node is a server accessible over 80/tcp which responds to HTTP GET
request (format of response is not processed).
TLS nodes are considered from HTTPS point of view. TLS node is a server
which successfully responded to TLS handshake over 443/tcp.
MX - is a mail relay, published in MX record of particular second-level
Lists of nodes are based on DNS data, thus only delegated and accessible
zones are included.
Autonomous systems with the largest number of Russian web services
Number of web services
The rating of Russian terminal ASs that contain web services, access to which is associated with a transborder hop (that is, there are non-Russian ASs in AS-PATH)
According to the typical way of recording BGP routes, we consider that the edge AS, containing the web service, is at the right-hand end of AS-PATH. We consider autonomous systems as transit, if they have two neighborsin the route AS-PATH. The route leading to the Russian edge AS is a transborder route if it contains at least one foreign (non-Russian) transit autonomous system which has the adjacent Russian AS on the left.

MSK-IX and DATAIX traffic exchange points
The world's largest operators
The RouteViews and RIS projects are used as data sources to build a connectivity graph of a specific autonomous system.
These data sources are used for building routes to the largest AS operators (part of the graph to the right of the AS under study).
The routing information from route servers of MSK-IX and DATAIX is used to build routes to traffic exchange points (IXP) MSK-IX and DATAIX (part of the graph to the left of the AS under study).
World's largest operators
The graph vertices are autonomous systems, the numbers of which are indicated near each vertex. When you hover the cursor on any vertex of the graph, information about the owner of this autonomous system is displayed. Each vertex of the graph is clickable. When pressed, you can get information about the selected AS.
Each edge of the graph reflects the BGP neighborhood defined by the AS-PATH attribute.
The straight edge between the AS and the AS of the IXP router server, means a direct link (Layer2) between the AS and IXP being examined.
If the connection to the IXP consists of several edges via transit AS, then the direct link (Layer2) is absent and the prefixes of the AS under investigation are delivered to IXP via the intermediate routers (Layer3) of other ASs that can affect the availability of the prefixes of the AS under investigation. There might be situations when transit routers could remove their AS from AS-PATH, then this situation treated as direct connection to IXP (Layer 2)
When you click on a graph edge in a separate window, prefixes are displayed, which AS-PATHs were used to build this edge.
Сlicking on a graph edge shows in a separate window the prefixes, whose AS-PATHs were used to build this edge.
Сlicking on the circle corresponding to the specific IXP, the graph "Chamomile" is drawn on a separate page.
The graph is inverted (the edge AS is shown on the left) for
convenience of presentation, because the graph can be quite long.
