What is NCE: an ECN dual mechanism to mitigate micro-bursts about?

Due to unique characteristics of datacenter applications, such as high volume and dynamic traffic patterns of short flows, microbursts significantly impact the application performance. Moreover, the reactive nature of congestion control (CC) algorithms makes CC ineffective against micro-bursts. This paper introduces the Notification of Change Events (NCE) mechanism. Compared to the Explicit Congestion Notification (ECN) schemes, where switches send information to hosts, NCE uses a dual approach that sends information from "transport layer" of sources to the network. This design provides a proactive in-network solution that mitigates micro-bursts in real-time with the help of the information from the application. Simulation results demonstrate NCE can improve the flow completion time of short flows up to 62% with negligible impacts on long flow throughput.
