RoCE services are sensitive to network failures and performance bottlenecks, which become more common as the RoCE network scales. In addition, some non-network problems behave like network problems and can waste troubleshooting time. However, existing ...

We propose a classifier that can identify ten common home network problems based on the raw textual output of networking tools such as ping, dig, and ip. Our deep learning model uses an encoder-only transformer architecture with a particular pre-...

SDN opens a new chapter in network troubleshooting as besides misconfigurations and firmware/hardware errors, software bugs can occur all over the SDN stack. As an answer to this challenge the networking community developed a wealth of piecemeal SDN ...

Can we get network latency between any two servers at any time in large-scale data center networks? The collected latency data can then be used to address a series of challenges: telling if an application perceived latency issue is caused by the network ...

Due to the heterogeneous and distributed nature of computer networks, the detection of misconfigurations and software/hardware failures is frequently reported to be notoriously non-trivial. The advent of SDN complicates the situation even more, since ...

Networks are getting larger and more complex, yet administrators rely on rudimentary tools such as and to debug problems. We propose an automated and systematic approach for testing and debugging networks called "Automatic Test Packet Generation" (ATPG)...

Networks are getting larger and more complex; yet administrators rely on rudimentary tools such as ping and traceroute to debug problems. We propose an automated and systematic approach for testing and debugging networks called "Automatic Test Packet ...

For analyzing network performance issues, there can be great utility in having the capability to measure directly from the perspective of end systems. Because end systems do not provide any external programming interface to measurement functionality, ...

Most home users are not able to troubleshoot advanced network issues themselves. Hours on the phone with an ISP's customer representative is a common way to solve this problem. With the advent of mobile devices with both Wi-Fi and cellular radios, ...

Netalyzr is a widely used network diagnostic and debugging tool that has collected 259,000 measurement sessions to date. To use Netalyzr, users visit its website, download an applet that proceeds to conduct a suite of tests and measurements, and obtain ...

Diagnosing problems in networks is a time-consuming and error-prone process. Existing tools to assist operators primarily focus on analyzing control plane configuration. Configuration analysis is limited in that it cannot find bugs in router software, ...

Monitoring and troubleshooting a large wireless mesh network (WMN) presents several challenges. Diagnosis of problems related to wireless access in these networks requires a comprehensive set of metrics and network monitoring data. Collection and ...

In this paper we present Netalyzr, a network measurement and debugging service that evaluates the functionality provided by people's Internet connectivity. The design aims to prove both comprehensive in terms of the properties we measure and easy to ...

A real-time optical network monitoring system named Smart Access Network _ Testing, Analyzing and Database (SANTAD) that combined remote controlling, centralized monitoring and troubleshooting, fault detection, optical switching as well as protection ...

Replicating content across a geographically distributed set of servers and redirecting clients to the closest server in terms of latency has emerged as a common paradigm for improving client performance. In this paper, we analyze latencies measured from ...

Chronic network conditions are caused by performance impairing events that occur intermittently over an extended period of time. Such conditions can cause repeated performance degradation to customers, and sometimes can even turn into serious hard ...

Changes in the end-to-end path between two hosts can lead to sudden changes in the round-trip time and available bandwidth, or even the complete loss of connectivity. Determining the reason for the routing change is crucial for diagnosing and fixing the ...
