Topic > Temporal predictable network for real-time data centric…

1. Introduction: With the advancement of computing and communication technologies, data centers support the characteristics of large scalability and high-performance data-intensive supercomputing capacity. Furthermore, next-generation data centers must manage and process exponentially growing volumes of data, which often arrive in time-sensitive streams from arrays of sensors and instruments or as simulation results [1]. Therefore, these urgent flows require real-time response from data centers, which becomes a major challenge for the next generation data center network. For example, healthcare imaging systems illustrate the need for both high data rates and real-time cataloging. Furthermore, high energy physics experiments, which generate high speeds and huge volumes of data that need to be processed and stored in real time [2]. In recent decades, much research effort has been put into data center network architecture to meet the growing data-intensive computing. However, these works only focus on scalability, energy efficiency, etc. [3, 11]. What surprises us is that a temporally predictable network for real-time data-centric computing has not yet been carefully studied. Furthermore, the current TCP/IP-based network architecture is unable to provide temporal predictability characteristics to data-centric processing. TCP/IP and CSMA/CD are the two factors that most influence timing control [4], because TCP/IP is a proven network and CSMA/CD uses an exponential backoff mechanism to avoid collisions. Therefore, it is important to propose a time-predictable network for data-centric processing to support accurate estimation of communication latency.2.
