Communication networks involve the transmission and reception of large volumes of data. Research indicates that network traffic volumes will continue to increase. These traffic volumes will be unprecedented and the behaviour of global information infrastructures when dealing with these data volumes is unknown. It has been shown that complex systems (including computer networks) exhibit self-organized criticality under certain conditions. Given the possibility in such systems of a sudden and spontaneous system reset the development of techniques to inform system administrators of this behaviour could be beneficial.

The SOCS system focuses on the combination of two dissimilar research concepts, namely sonification (a form of auditory display) and self-organized criticality (SOC). The SOCS system sonifies in real time a computer network’s self-organized criticality to alert the network administrators of both normal and abnormal network traffic and operation.

Source code for the Pure Data patch and example sonifications can be found in the project’s repository.
