This workshop covers network protocols and mechanisms for a low-latency Internet developed as part of the "READY" project. The presented work takes a starting point in cloud-based Internet applications, in the domains of IoT, automation, and media distribution. Low-latency techniques covered include multi-path selection/routing, congestion control, queueing algorithms, software defined networking for cloud-based services, and predictable latency for automation.

Increasing the communication bitrate, or throughput, has been the focus of research and product development since the birth of communication systems. Network access subscriptions are graded in different bitrates and performance is measured in throughput. The outcome is network access up to gigabit rates or more, well satisfying the throughput needs of applications and services.

However, recently communication latency has gained well needed attention in academia and industry. With the increased bitrates, latency is often the limiting factor, and has therefore become the most important performance metric for many applications and services. In contrast to throughput, latency is an additive metric, and therefore requires to be carefully managed along the whole end-to-end communication path; that is, removing single bottlenecks is rarely a sufficient action.

We show how to efficiently use multipath communication to improve application performance, taking scheduling and interface selection into account. For automation and Industry 4.0 we demonstrate the benefits of using software defined networking, programmable dataplanes and multipath communication for reduced latency and increased fault tolerance. This is important for reducing the control loop latency for cloud based IoT architectures and meeting strict communication deadlines in future automation networks. We carry out large-scale network measurement studies to understand network latency characteristics and to evaluate the benefit of low latency protocols and mechanisms.
