We present a decade of evolution and production experience with Jupiter datacenter
network fabrics. In this period Jupiter has delivered 5x higher speed and capacity, 30 …

Clock synchronization is critical for many datacenter applications such as distributed
transactional databases, consistent snapshots, and network telemetry. As applications have …

While prior work has explored many proposed datacenter designs, only two designs, Clos-
based and expander-based, are generally considered practical because they can scale …

The difficulty in gaining visibility into the fine-timescale hop-level congestion state of
networks has been a key challenge faced by congestion control (CC) protocols for decades …

We describe our experience building and deploying a demand-oblivious optically-switched
network based on the RotorNet and Opera architectures. We detail the design, manufacture …

Designing efficient interconnects to support high-bandwidth and low-latency communication
is critical toward realizing high performance computing (HPC) and data center (DC) systems …

Most recent datacenter topology designs have focused on performance properties such as
latency and throughput. In this paper, we explore a new dimension, life cycle management …

To reduce cost, datacenter network operators are exploring blocking network designs. An
example of such a design is a" spine-free" form of a Fat-Tree, in which pods directly connect …

Network management is becoming increasingly automated, and automation depends on
detailed, explicit representations of data about the state of a network and about an operator's …

Many optical circuit switched data center networks (DCN) have been proposed in the last
decade to attain higher capacity and topology reconfigurability, though commercial adoption …
