A computer-implemented method of obfuscating communication traffic patterns occurring over a cloud-based communication infrastructure includes detecting first data communication sessions between a first communications device a second communications device via a first computer server using a network protocol. An information content threshold value associated with the first data communication sessions is accessed. A traffic pattern based on the first data communication sessions is also accessed, whereby the traffic pattern determines communication occurrences between the first and the second communication devices over a predefined time period. An information content value associated with the accessed traffic pattern is determined. Using the network protocol, the first data communication sessions via the first computer server is re-routed to a second data communication session via a second computer server based on a detection of the information content value associated with the accessed traffic pattern exceeding the information content threshold value.
