A Black-Box Approach to Latency and Throughput Analysis
To enable fast and reliable delivery of mobile text messages (SMS), special bidirectional protocols are often used. Measuring the achieved throughput and involved latency is however non-trivial, due to the complexity of these protocols. Modifying an existing system would incur too much of a risk, so instead a new tool was created to analyse the log files containing information about this traffic in a black-box fashion. When the produced raw data was converted into graphs, they gave new insights into the behaviour of both the protocols and the remote systems involved.
