CASSINI: Network-Aware Job Scheduling in Machine Learning Clusters
Sudarsanan Rajasekaran, Manya Ghobadi, Aditya Akella
We present CASSINI, a network-aware job scheduler for machine learning (ML) clusters. CASSINI introduces a novel geometric abstraction to consider the communication pattern of diff…
SFC: Near-Source Congestion Signaling and Flow Control
Yanfang Le, Jeongkeun Lee, Jeremias Blendin +11
State-of-the-art congestion control algorithms for data centers alone do not cope well with transient congestion and high traffic bursts. To help with these, we revisit the concept…
Impact of RoCE Congestion Control Policies on Distributed Training of DNNs
Tarannum Khan, Saeed Rashidi, Srinivas Sridharan +3
RDMA over Converged Ethernet (RoCE) has gained significant attraction for datacenter networks due to its compatibility with conventional Ethernet-based fabric. However, the RDMA pr…
PL2: Towards Predictable Low Latency in Rack-Scale Networks
Yanfang Le, Radhika Niranjan Mysore, Lalith Suresh +4
High performance rack-scale offerings package disaggregated pools of compute, memory and storage hardware in a single rack to run diverse workloads with varying requirements, inclu…
D2R: Dataplane-Only Policy-Compliant Routing Under Failures
Kausik Subramanian, Anubhavnidhi Abhashkumar, Loris D'Antoni +1
In networks today, the data plane handles forwarding---sending a packet to the next device in the path---and the control plane handles routing---deciding the path of the packet in…
Tiramisu: Fast and General Network Verification
Anubhavnidhi Abhashkumar, Aaron Gember-Jacobson, Aditya Akella
Today's distributed network control planes support multiple routing protocols, filtering mechanisms, and route selection policies. These protocols operate at different layers, e.g.…
Correctness and Performance for Stateful Chained Network Functions
Junaid Khalid, Aditya Akella
Network functions virtualization (NFV) allows operators to employ NF chains to realize custom policies, and dynamically add instances to meet demand or for failover. NFs maintain d…
Active Switching: Packet Steering Flow Annotations
Saul St. John, Aditya Akella
Our previous experience building systems for middlebox chain composition and scaling in software-defined networks has revealed that existing mechanisms of flow annotation commonly…
Stratos: A Network-Aware Orchestration Layer for Virtual Middleboxes in Clouds
Aaron Gember, Anand Krishnamurthy, Saul St. John +6
Enterprises want their in-cloud services to leverage the performance and security benefits that middleboxes offer in traditional deployments. Such virtualized deployments create ne…
