This document summarizes a presentation about communication management in M2M horizontal platforms. It introduces Sierra Wireless as a global leader in devices and cloud services for the Internet of Things. It describes a "network horror story" that illustrates the problems that can occur when M2M devices communicate without management. Finally, it discusses solutions being developed at 3GPP and oneM2M to enable communication management, including congestion control and policies to prevent traffic storms.

The bad news – this is no made-up story
• Constant load of periodic communications
• Traffic Storms
• GSMA: 375k IoT devices led to a 48h network breakdown in 2013
• ENISA: 45 incidents for each time 1.4 Mio mobile users in 2013
