NETWORKING

The maximum transmission unit (MTU) is the largest number of bytes an individual datagram can have without either being fragmented into smaller datagrams or being dropped along the path between its source and its destination. For Ethernet frames—and many other types of packets—that number is 1500 bytes, and it generally meets the requirements of traffic that can cross the public internet intact. So, if 2000-byte Ethernet packets arrive at a router, it will split their…

As we age, it’s recommended by doctors that we invest in ourselves with a balanced diet, adequate sleep, and regular exercise to maintain optimal health. Similarly, as enterprises and service providers’ businesses grow, they must continually invest in their infrastructures to maintain optimal connectivity for employees and customers. In the best of times, this was a challenge. Then came the pandemic, introducing the challenge of sustaining remote – and eventually hybrid – work. With hybrid…

The Cisco IoT Operations Dashboard provides operations teams with a centralized, cloud-based dashboard to securely deploy, monitor, and troubleshoot device connectivity. Using this secure connectivity as a foundation, that same dashboard then enables you to extract, transform, govern and deliver data from IoT edge devices to the cloud with Cisco Edge Intelligence, install and manage your containerized edge applications and to deploy a broad range of industrial IoT sensors with Cisco Industrial Asset Vision. Once…

No one buys a server for its own sake. People buy servers to run applications. Cisco UCS servers are being used from core infrastructure (DNS, DHCP, etc.) to mission critical / business critical apps. It’s an app-centric world and Cisco X-Series is here for more of them. With six local drives on a UCS X210c node and UCS X-Fabric capabilities, UCS X-Series modular servers blur the lines for what is considered a traditional blade or…

There’s rich — Amazon’s Jeff Bezos with not quite $200-billion and Microsoft’s Bill Gates with $132-billion — and then there’s Elon Musk rich: Approximately $241-billion. But, according to a note, “SpaceX Escape Velocity … Who Can Catch Them?” by Morgan Stanley‘s head of auto and space research Adam Jonas, SpaceX will launch him into being the first trillionaire.  True, SpaceX makes up less than 17% of Musk’s $241.4 billion net worth, according to the Bloomberg Billionaires…

This guest blog was written by Aaron Sherrill, Senior Research Analyst at 451 Research, part of S&P Global Market Intelligence.  Set the Stage: A World Without XDR Security operations teams at most organizations are overwhelmed by the sheer number of security products they’re required to manage. Over the course of many years, security teams have stitched together a robust security stack with dozens, if not hundreds, of disparate, siloed security tools, each aimed at protecting specific…

Part of the Hybrid Work Success Series In my last Hybrid work: Revolution or evolution newsroom article, I shared my thoughts about how hybrid work is really a revolution. It’s not incremental. It’s the next normal. Admittedly, how I work now has fundamentally changed. There are days where I am seemingly everywhere at once – working from my home office, then at the office, and finally at the soccer field. All in a single day….

It can take years for a CPU to go from design to silicon, so Arm is helping developers get a jump on things by putting virtual models of its chip designs in the cloud. The virtual models will allow developers to write and test applications before the actual silicon ships. Dubbed Arm Total Solutions for IoT, the project is a full-stack solution intended for Internet of Things applications and use cases. Arm says the early…
