The tech committee would like to announce a new accepted talk. Tom Herbert will talk about the need for very critical (life or death!) infrastructure need for IOT. More details on the talk: ---- This talks presents the motivation and direction to support the emerging class of IoT applications and protocols that require latencies measured in milliseconds on the Internet. These may be thought of as "life-critical applications" in the sense that they could be a matter of life and death to be correct. For example, a camera monitoring an intersection by a school may detect a child darting out into traffic. A device attached to the camera may send a warning to an autonomous vehicle to apply brakes to avoid hitting the child. The difference in reaction time between the an automated system and human is stark-- about 40 msecs compared to 500 msecs or more for a human. Real-time IoT protocols need to be implemented with very low latency from hazard detection to response, strict latency bounds, be highly available, be secure (critical messages can't be spoofed), and be resistant to DDOS. A primary use case for such applications, as exhibited in the above example, is so-called Vehicle to Infrastructure communications (V2X). This implies that communicating devices may be highly mobile needing a solution such as ILA or MobileIP. The underlying network may also have different flavors including Dedicated Short-Range Communications (DSRC) which is standardized as 802.11p, 4G or the emerging 5G standard, as well as traditional WIFI. In order to achieve the tight latency bounds the application, network stack, network, scheduling, must all be tightly coordinated. Information is usually time sensitive with deadlines of usefulness such that techniques such as forward error correction are more likely to be used than traditional reliable protocols such as TCP. DTLS handshake must also be low latency, as well as any hand-off for implemented MobileIP. ----- cheers, jamal
