| CrossCheck: Input Validation for WAN Control Systems | NSDI '26 | 2026-05-04 |
CrossCheck validates SDN controller inputs by repairing telemetry via democratic trust propagation and then cross-checking controller topology and demand… | ||
| Harvesting Memory-bound CPU Stall Cycles in Software with MSH | 18th USENIX Symposium on Operating Systems Design and Implementation (OSDI '24) | 2024-07-10 |
A software system called MSH instruments binaries via profile-guided binary instrumentation, adds prefetching and bounded scavenger yields, and uses runtime… | ||
| Invisinets: Removing Networking from Cloud Networks | NSDI 2023 | 2023-04-17 |
Invisinets replaces VPCs and gateways with per-endpoint parameters: every endpoint gets a public endpoint IP and optional service IPs, connectivity uses… | ||
| LOCA: A Location-Oblivious Cellular Architecture | NSDI 2023 | 2023-04-17 |
LOCA claims to hide user location from operators while still delivering identity-based services by splitting duties between an MVNO-style broker and… | ||
| Efficient Scheduling Policies for Microsecond-Scale Tasks | 19th USENIX Symposium on Networked Systems Design and Implementation (NSDI '22) | 2022-04-04 |
Simulations model 1μs tasks with measured overheads (100 ns to move a task, 5 μs to add a core) and show work stealing consistently yields the best… | ||
| On the Use of ML for Blackbox System Performance Prediction | NSDI ’21 | 2021-04-12 |
Evaluates six ML models on 13 real applications and finds 12 of 13 show inherent variability that limits prediction accuracy, with the oracle error exceeding… | ||
| Democratizing Cellular Access with AnyCell | Magma Developers Conference 2021 | 2021-02-03 |
Claim: let any user attach to any operator on demand without pre-established trust by moving subscriber/auth and billing into a broker and mobility into the… | ||
| Fast and Efficient Container Startup at the Edge via Dependency Scheduling | 3rd USENIX Workshop on Hot Topics in Edge Computing (HotEdge '20) | 2020-06-25 |
Container startup time is dominated by image pulls (average ~20s from a cloud repo), so the system treats image layers as dependency units and schedules pods… | ||
| TimeCrypt: Encrypted Data Stream Processing at Scale with Cryptographic Access Control | NSDI 2020 | 2020-02-25 |
TimeCrypt encrypts time-series end-to-end using a symmetric homomorphic key-canceling construction plus per-window key streams and a tree-based key-derivation… | ||
| Keynote: Accelerating Innovation with Lean NFV | Open Networking Summit North America 2019 | 2019-04-03 |
Proposal advocates using a key value store (eg etcd) as the single universal integration point, with MANO decomposed into independent microcontrollers… | ||
| SafeBricks: Shielding Network Functions in the Cloud | NSDI '18 | 2018-04-09 |
SafeBricks claims to run real network functions in cloud enclaves so both headers and payloads stay encrypted outside the enclave and NF code/rules remain… | ||
| ResQ: Enabling SLOs in Network Function Virtualization | NSDI '18 | 2018-04-09 |
ResQ enforces SLOs by combining Intel RDT cache allocation (CAT) with careful I/O buffer sizing to fix a discovered leaky DMA problem that lets DMA pollute the… | ||
| Elastic Scaling of Stateful Network Functions | NSDI '18 | 2018-04-09 |
S6 implements a distributed shared object (DSO) space that keeps state objects local for common accesses but makes them visible and migratable across… | ||
