AdvNet: Revealing Performance Issues in Network Protocols by Generating Adversarial Environments
Shehab Sarar Ahmed, William Sentosa, Yinjie Zhang +6
Infrastructure protocols like Congestion Control (CC) seek to provide reliable performance across a wide range of Internet environments. Currently, protocol designers assess perfor…
GATE: GPU-Accelerated Traffic Engineering for the WAN
Rahul Bothra, Alexander Krentsel, Saptarshi Mandal +4
Traffic engineering (TE) has become a crucial tool for enforcing routing policy and maintaining operational efficiency in large networks. Existing TE solutions pick an objective fu…
Assistants, Not Architects: The Role of LLMs in Networked Systems Design
Pratyush Sahu, Rahul Bothra, Venkat Arun +3
Designing the architecture of modern networked systems requires navigating a large, combinatorial space of hardware, systems, and configuration choices with complex cross-layer int…
Fine-grained Distributed Data Plane Verification with Intent-based Slicing
Kuan-Yen Chou, Santhosh Prabhu, Giri Subramanian +4
Data plane verification has grown into a powerful tool to ensure network correctness. However, existing methods with monolithic models have memory requirements tied to network size…
Caramel: Accelerating Decentralized Distributed Deep Learning with Computation Scheduling
Sayed Hadi Hashemi, Sangeetha Abdu Jyothi, Brighten Godfrey +1
The method of choice for parameter aggregation in Deep Neural Network (DNN) training, a network-intensive task, is shifting from the Parameter Server model to decentralized aggrega…
Plankton: Scalable network configuration verification through model checking
Santhosh Prabhu, Kuan-Yen Chou, Ali Kheradmand +2
Network configuration verification enables operators to ensure that the network will behave as intended, prior to deployment of their configurations. Although techniques ranging fr…
Dissecting Latency in the Internet's Fiber Infrastructure
Ilker Nadi Bozkurt, Waqar Aqeel, Debopam Bhattacherjee +5
The recent publication of the `InterTubes' map of long-haul fiber-optic cables in the contiguous United States invites an exciting question: how much faster would the Internet be i…
cISP: A Speed-of-Light Internet Service Provider
Debopam Bhattacherjee, Sangeetha Abdu Jyothi, Ilker Nadi Bozkurt +8
Low latency is a requirement for a variety of interactive network applications. The Internet, however, is not optimized for latency. We thus explore the design of cost-effective wi…
Internet Congestion Control via Deep Reinforcement Learning
Nathan Jay, Noga H. Rotman, P. Brighten Godfrey +2
We present and investigate a novel and timely application domain for deep reinforcement learning (RL): Internet congestion control. Congestion control is the core networking task o…
Towards a Speed of Light Internet
Ankit Singla, Balakrishnan Chandrasekaran, P. Brighten Godfrey +1
In principle, a network can transfer data at nearly the speed of light. Today's Internet, however, is much slower: our measurements show that latencies are typically more than one,…
High Throughput Data Center Topology Design
Ankit Singla, P. Brighten Godfrey, Alexandra Kolla
With high throughput networks acquiring a crucial role in supporting data-intensive applications, a variety of data center network topologies have been proposed to achieve high cap…
A cost-benefit analysis of low latency via added utilization
Ashish Vulimiri, P. Brighten Godfrey, Sri Varsha Gorge +2
Several recently proposed techniques achieve latency reduction by trading it off for some amount of additional bandwidth usage. But how would one quantify whether the tradeoff is a…
Scalable Routing on Flat Names
Ankit Singla, P. Brighten Godfrey, Kevin Fall +2
We introduce a protocol which routes on flat, location-independent identifiers with guaranteed scalability and low stretch. Our design builds on theoretical advances in the area of…
Jellyfish: Networking Data Centers Randomly
Ankit Singla, Chi-Yao Hong, Lucian Popa +1
Industry experience indicates that the ability to incrementally expand data centers is essential. However, existing high-bandwidth network designs have rigid structure that interfe…
BGP Stability is Precarious
P. Brighten Godfrey
We note a fact which is simple, but may be useful for the networking research community: essentially any change to BGP's decision process can cause divergence --- or convergence wh…
Network Coding for Distributed Storage Systems
Alexandros G. Dimakis, P. Brighten Godfrey, Yunnan Wu +2
Distributed storage systems provide reliable access to data through redundancy spread over individually unreliable nodes. Application scenarios include data centers, peer-to-peer s…
