Predictive Switch-Controller Association and Control Devolution for SDN Systems
Xi Huang, Simeng Bian, Ziyu Shao +1
For software-defined networking (SDN) systems, to enhance the scalability and reliability of control plane, existing solutions adopt either multi-controller design with static swit…
Joint Switch-Controller Association and Control Devolution for SDN Systems: An Integration of Online Control and Online Learning
Xi Huang, Yinxu Tang, Ziyu Shao +2
In software-defined networking (SDN) systems, it is a common practice to adopt a multi-controller design and control devolution techniques to improve the performance of the control…
Simulating Performance of ML Systems with Offline Profiling
Hongming Huang, Peng Cheng, Hong Xu +1
We advocate that simulation based on offline profiling is a promising approach to better understand and improve the complex ML systems. Our approach uses operation-level profiling…
Node-Constrained Traffic Engineering: Theory and Applications
George Trimponias, Yan Xiao, Xiaorui Wu +2
Traffic engineering (TE) is a fundamental task in networking. Conventionally, traffic can take any path connecting the source and destination. Emerging technologies such as segment…
NetKernel: Making Network Stack Part of the Virtualized Infrastructure
Zhixiong Niu, Hong Xu, Peng Cheng +4
This paper presents a system called NetKernel that decouples the network stack from the guest virtual machine and offers it as an independent module. NetKernel represents a new par…
Saec: Similarity-Aware Embedding Compression in Recommendation Systems
Xiaorui Wu, Hong Xu, Honglin Zhang +2
Production recommendation systems rely on embedding methods to represent various features. An impeding challenge in practice is that the large embedding matrix incurs substantial m…
Flash: Efficient Dynamic Routing for Offchain Networks
Peng Wang, Hong Xu, Xin Jin +1
Offchain networks emerge as a promising solution to address the scalability challenge of blockchain. Participants directly make payments through a network of payment channels witho…
Centrality-based Middlepoint Selection for Traffic Engineering with Segment Routing
George Trimponias, Yan Xiao, Hong Xu +2
Segment routing is an emerging technology to simplify traffic engineering implementation in WANs. It expresses an end-to-end logical path as a sequence of segments through a set of…
Dynamic Switch-Controller Association and Control Devolution for SDN Systems
Xi Huang, Simeng Bian, Ziyu Shao +1
In software-defined networking (SDN), as data plane scale expands, scalability and reliability of the control plane have become major concerns. To mitigate such concerns, two kinds…
Benchmarking NFV Software Dataplanes
Zhixiong Niu, Hong Xu, Yongqiang Tian +3
A key enabling technology of NFV is software dataplane, which has attracted much attention in both academia and industry recently. Yet, till now there is little understanding about…
RepNet: Cutting Tail Latency in Data Center Networks with Flow Replication
Shuhao Liu, Wei Bai, Hong Xu +2
Data center networks need to provide low latency, especially at the tail, as demanded by many interactive applications. To improve tail latency, existing approaches require modific…
Low Latency Datacenter Networking: A Short Survey
Shuhao Liu, Hong Xu, Zhiping Cai
Datacenters are the cornerstone of the big data infrastructure supporting numerous online services. The demand for interactivity, which significantly impacts user experience and pr…
Spot Transit: Cheaper Internet Transit for Elastic Traffic
Hong Xu, Baochun Li
We advocate to create a \emph{spot} Internet transit market, where transit is sold using the under-utilized backbone capacity at a lower price. The providers can improve profit by…
RepFlow: Minimizing Flow Completion Times with Replicated Flows in Data Centers
Hong Xu, Baochun Li
Short TCP flows that are critical for many interactive applications in data centers are plagued by large flows and head-of-line blocking in switches. Hash-based load balancing sche…
Reducing Electricity Demand Charge for Data Centers with Partial Execution
Hong Xu, Baochun Li
Data centers consume a large amount of energy and incur substantial electricity cost. In this paper, we study the familiar problem of reducing data center energy cost with two new…
