The Radial Traffic Analyzer visualizes network traffic using a radial hierarchical layout. The radial visualization was chosen to display data with the same level of importance. Users interpreting a left-to-right layout may assign more importance to an item on one side due to the cultural reading direction. In the default configuration, the Radial Traffic Analyzer uses four concentrical rings, each one representing an attribute of the transferred packets.

[[Image:Rta_small.jpg]]

The rings in this example show the following information, from the innermost to the outermost ring: 
1. Source IP adress 
2. Destination IP 
3. Source port number 
4. Destination port number. 
The share in total traffic determines the size of a single circle segment. To improve readability, entries with the same value (e.g., the same IP, or the same port number) always use the same colour. Popular port numbers appear in reserved, unique colours (e.g. green is always used for port 80 - HTTP), which are not used again to display something else. Traffic over secured channels is shown in brighter colours, whereas traffic over unsecured channels appears in darker colour.

Circle segments are sorted on a ring, and grouped by the attributes on the inner rings. The next figure shows the design rationale:

[[Image:Rta_sort.jpg]]

The Radial Traffic Analyzer allows a variety of user interaction. Entries and their associated traffic can be filtered by single-clicking a circle segment. The order of the rings can be adapted to the users' needs, as well as the number of the rings, or their attributes. For example, the Radial Traffic Analyzer can be configured to display security alerts generated by an intrusion detection system:

[[Image:Rta_sec.jpg]]

As seen in the figure above, the innermost circle can be used to limit the source of network traffic to one specified country. For this purpose, the Radial Traffic Analizer uses the [http://www.maxmind.com Maxmind’s GeoIP Database] to evaluate the geo-location information. Geographical information is arranged on a treemap using the HistoMap algorithm; each geographical unit is matched to a rectangle. The amount of traffic determines the rectangle size.

As per April 2007, there are no evaluations or reference implementations of the Radial Traffic Analyzer.

The Radial Traffic Analyzer visualizes network traffic using a radial hierarchical layout. The radial visualization was chosen to display data with the same level of importance.

In the default configuration, the Radial Traffic Analyzer uses four concentrical rings, each one representing an attribute of the transferred packets.

[[Image:Rta_small.jpg]]

The rings in this example show the following information, from innermost to outermost:
1. Source IP adress contained in the packet,
2. Destination IP
3. Source port number
4. Destination port number.
The share in total traffic determines the size of a single circle segment. To improve readability, entries with the same value (e.g., the same IP, or the same port number) always use the same colour. Popular port numbers appear in reserved, unique colours (e.g. green is always used for port 80 - HTTP), which are not used again to display something else. Traffic over secured channels is shown in brighter colours, whereas traffic over unsecured channels appears in darker colour.

Circle segments are sorted on a ring, and grouped by the attributes on the inner rings. The next figure shows the design rationale:

The Radial Traffic Analyzer allows a variety of user interaction. Entries and their associated traffic can be filtered by single-clicking a circle segment.

The Radial Traffic Analyzer visualizes network traffic in a radial hierarchical layout. In the default configuration the Radial Traffic Analyzer uses four concentrical rings, each representing one attribute of the transferred packets.

[[Image:Rta_small.jpg]]

The first ring shows the IP adresses of the packet source, the second ring shows the destination IP, the third ring shows the source port number and the outermost ring the destination port number. The size of the area of each entry specifies the fraction of the traffic payloads. To improve the readability, entries with the same values (same IP or same port number) are drawn in the same colour, entries of prominent ports in unique colours (e.g. port 80 - HTTP or port 110 - POP3) and traffic over secured channels is shown in brighter colours.

Each ring uses the rings further inside for grouping and sorting, as shown in the next figure:

[[Image:Rta_sort.jpg]]

The Radial Traffic Analyzer allows a lot of user interactions. The order of the rings can be changed adapted to the users needs, as well as the number of the rings or their attribute types. For example, the Radial Traffic Analyzer can be configured to show up security alerts generated by an intrusion detection system:

[[Image:Rta_sec.jpg]]

As seen in the figure above, the innermost circle can be used to limit the visualization of network traffic to one specified country. For that purpose, the Radial Traffic Analizer uses the [http://www.maxmind.com Maxmind’s GeoIP Database] to evaluate the geo-location information, parts the available display space into rectangles using the HistoMap algorithm and assigns each country to one rectangle. The bigger the rectangles the higher the traffic payloads from or to each country.

== Short Description ==

{{Quotation|The Radial Traffic Analyzer display is perfectly suitable to show grouped information in the inner circles while presenting related detail information on the outer circles. It is complemented by appropriate interaction techniques like hints on mouse-over, drag & drop to adapt the order of the rings, filtering using clicks and details accessible via a popup menu.| [[Keim, Daniel]] et al., 2006}}

== Figures ==

The Radial Traffic Analyzer visualizes network traffic in a radial hierarchical layout. In the default configuration the Radial Traffic Analyzer uses four concentrical rings, each representing one attribute of the transferred packets.

The innermost ring shows the IP adresses of the packet source, the second ring shows the destination IP, the third ring shows the source port number and the outermost ring the destination port number. The size of the area of each entry specifies the fraction of the traffic payloads. To improve the readability, entries with the same values (same IP or same port number) are drawn in the same colour, entries of prominent ports in unique colours (e.g. port 80 - HTTP or port 110 - POP3) and traffic over secured channels is shown in brighter colours.

Each ring uses the rings further inside for grouping and sorting, as shown in the next figure:

The Radial Traffic Analyzer allows a lot of user interactions. The order of the rings can be changed adapted to the users needs, as well as the number of the rings or their attribute types. For example, the Radial Traffic Analyzer can be configured to show up security alerts generated by an intrusion detection system:
