With many businesses having switched to part-time or even full-time remote work, the challenge for IT teams becomes how to provide quick and efficient support for network problems remotely. In this article, we’re running you through how SPI Health and Safety is using Obkio to monitor network performance and troubleshoot performance issues for all their remote call center employees.
Multi-cloud hybrid cloud environments, microservices architectures, the rapid growth in the number of mission-critical applications, and the sudden surge in remote work have made enterprise networks exponentially complex. These networks are often not designed to handle the variety of physical and wireless media that’s become common today, for instance, the number of video calls, data transfer through screen sharing, etc.
The ‘Internet of Things’ was first coined to help people understand the concept of digital appliances that could communicate with an app or central hub. If you’ve been to CES at any point in the last decade, you could see many examples on the show floor, such as connected weight scales or a connected fridge. But these early examples of ‘connected’ tech felt more gimmicky than useful, and were largely contained to the consumer electronics industry.
Securing your company's network against online threats can seem like a daunting task. There are so many different e-commerce security threats, and it can be hard to know where to start or if you're adequately protected against all of them. One important weapon in the fight for network security is your firewall. Although your firewall will remain hidden from view for most of your employees most of the time, you shouldn't forget about it.
In the latest episode of Network AF, your host Avi Freedman chats with Zac Smith. Zac is a 20-year networking veteran, the managing director of Equinix Metal, and a double bass player.

This blog post is part of our data centre networking series: With the explosion of application traffic and the multiplication of data centre workloads during the last decade, east-west traffic greatly increased and ended up impacting the traditional north-south based architectures. This raised the need to review the entire data centre architecture while keeping the goal of meeting performance, security, and monitoring requirements.
This blog post is part of our data centre networking series: With the development of open source software-defined networking solutions, virtualisation took a progressively more important place in modern data centres. Concepts like virtual switching and routing became part of the data centre networking scene, with OVS as a pioneering example.

Learn four methods to keep an eye on the status and operational condition of the Flowmon system.
About 3 months ago, I spoke to one of our customers, an employee of an unnamed government entity, about Kemp Flowmon Packet Investigator (FPI). After giving him a short demonstration, he told me a story that happened to him just a couple of days earlier.
Apps like VoIP, Unified Communications, and Video Conferencing can be greatly affected by network problems. To avoid performance issues, network engineers can implement QoS. Keep reading to learn about implemnting network QoS monitoring with DSCP.
Many companies today rely on SaaS connections in order for the business to function. Some users simply can’t operate in their job when an application becomes unavailable. When hundreds of users are impacted, this can cost a company serious money. That’s why keeping a proverbial finger on the pulse of application performance is generally worth the effort. But, it isn’t easy. Many popular SaaS applications are delivered from hundreds of locations around the world.
Network traffic analysis serves many purposes. It’s used for general network monitoring, security reasons, as well as the debugging of network issues. It can be helpful not only to network administrators but also to application developers. In this post, you’ll learn what network traffic analysis tools actually are and what are the top five you should know about.

This post will be updated over the next several days. Recently, a Remote Code Execution vulnerability was discovered in the Apache Log4J library. This vulnerability, which is tracked in CVE-2021-44228, dubbed Log4Shell, allows attackers to execute arbitrary code on affected systems. While HAProxy Enterprise, HAProxy ALOHA, and other products within the HAProxy Technologies portfolio are not impacted by this (they do not use the Log4J library at all), you can use them to block the attack.
Most of existing solutions for SNMP monitoring need you to configure complex dashboards. With Bleemeo, you can start in 30s to monitor your existing SNMP equipments. You need to add an extra component that will be in charge of fetching metrics of all your network equipments.
“Work from anywhere” is now a common occurrence. With so many companies now dependent on a distributed workforce, IT teams need to be able to quickly diagnose and troubleshoot WiFi problems. Moreover, they, themselves, are often working remotely. In order to successfully do their jobs, consistent WiFi is obviously essential for remote workers.

As consumers, we are all intimately aware of our individual dependence on the internet. Now consider that dependency and apply it to the business-critical services that your company uses daily. Nearly overnight, companies are at the mercy of the internet, a network of public networks as nearly all employees work remotely and apps that were once hosted internally move to external SaaS providers.
It was at the turn of the millennium. I was one of the first engineers entrusted with the job of installing Network Computers, the thin client that Oracle had just introduced as an alternative to personal computers. During the process, as I described the benefits of network computing and three-tier architecture to customers, there was a palpable skepticism all around. Twenty years have passed since. Client-server gave way to three-tier architecture, and with the internet came cloud computing.
Broadcom Software just announced the intention to acquire AppNeta, a pioneer in end-user experience over the internet.

AppNeta adds solutions, technologies, and people that will enable DX NetOps to deliver more value to our customers and partners.
The major challenge facing communications service providers (CSPs) is not about handling ever-growing bandwidth demands without increasing Capex. Smart selection of network technologies that leverage advances in aggregating, routing, and transmitting bits largely have the answer for that. The much more pressing challenge is on the services front, from competition, substitution, and the inability to maximize revenues. These concerns reduce the top line and restrict CSPs’ ability to maneuver.
