Technology Brief:

Researchers at New Jersey Institute of Technology in the Department of Electrical and Computer Engineering have invented a cost-effective and self-sufficient solution for measuring the time network interfaces spend receiving Internet packets at Internet hosts before they are processed. This information is critical to determine host response time during data communications on the Internet.


Response time of Internet hosts is an important parameter because it plays a major role in determining the performance of various network parameters and helping to monitor network state and geo-temporal data transmissions for delay-sensitive applications, such as end-to-end delay, IP geolocation, and electronic trading. At high transmission speeds, this packet travel is affected by the now common hardware artifact at hosts called interrupt coalescence period (IC period). Currently, no solution is available that can estimate IC period of Internet hosts. This breakthrough invention can estimate IC period of Internet hosts using a client-server based software system. It is a cost-effective solution as it does not require any instrumentation at the point of measurement.  Further, it is a self-standing solution as it measures IC with high accuracy and on remote hosts without requiring any administrative and Infrastructural network support.
