It allows the user to see traffic load on a network over time in graphical form. It was originally developed by Tobias Oetiker and Dave Rand to monitor router traffic, but has developed into a tool that can create graphs and statistics for almost anything. MRTG is written in Perl and can run on Windows, Linux, Unix, Mac OS and NetWare.
PRTG (Paessler Router Traffic Grapher) is a network monitoring software developed by Paessler GmbH. It monitors system conditions like bandwidth usage or uptime and collect statistics from miscellaneous hosts such as switches, routers, servers, and other devices and applications.
Some tools measure traffic by sniffing and others use SNMP, WMI or other local agents to measure bandwidth use on individual machines and routers. However, the latter generally do not detect the type of traffic, nor do they work for machines which are not running the necessary agent software , such as rogue machines on the network, or machines ...
NetFlow is a feature that was introduced on Cisco routers around 1996 that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination traffic, class of service, and the causes of congestion.
In telecommunications networks, traffic intensity is a measure of the average occupancy of a server or resource during a specified period of time, normally a busy hour. It is measured in traffic units ( erlangs ) and defined as the ratio of the time during which a facility is cumulatively occupied to the time this facility is available for ...
This is a list of countries (or regions) by total road network size, both paved and unpaved.Also included is additional data on road network density and the length of each country or region's controlled-access highway network (also known as a motorway, expressway, freeway, etc.), designed for high vehicular traffic.
The SNMP based approach retrieves data from Router and Switch MIBs in order to build the network map. The active probing approach relies on a series of traceroute-like probe packets in order to build the network map. The route analytics approach relies on information from the routing protocols to build the network map. Each of the three ...
Southbound traffic is data entering the data center (through a firewall and/or other networking infrastructure). Data exiting the data center is northbound traffic, commonly routed through a firewall [1] to Internet space. The other direction of traffic flow is east-west traffic which typically indicates data flow within a data center. [2 ...
