Deterministic Latency Computing: Real-Time Processing Infrastructure in Data Centers with Jitter-less Computing Technology

This presentation details a collaborative initiative by NTT, NEC, and Fujitsu, supported by an NEDO (New Energy and Industrial Technology Development Organization) grant, to develop a novel approach to real-time system construction planned for commercialization after 2027. We seek partners for future collaboration to explore and implement use cases for this technology, focusing on opportunities beyond 2027.

Achieving simultaneous operation of multiple real-time systems with strict time constraints often necessitates distributing computing resources closer to the edge to mitigate the jitter of computation time. However, this approach compromises aggregation efficiency. Conversely, centralizing processing in data centers introduces challenges related to the jitter of data transfer times from the edge and the jitter of computation time within the data center, making it challenging to guarantee real-time performance. While Open All Photonics Network (APN) can stabilize transfer delays between the edge and the data center, the jitter of computation time remains a significant obstacle.

This presentation introduces a new concept for computation with deterministic latency within the data center. Integrating this concept with Open APN, we aim to enable the construction of real-time systems on the data center side, ultimately reducing power consumption through improved aggregation efficiency.
