Generational advancements in transistor density have led to extraordinarily powerful devices, from smart phones to high-capacity switches and routers. Coherent digital signal processors (DSPs), the “brains” inside coherent optical modules, have benefitted from Moore’s law, enabling tremendous optical transmission capacity and capabilities that were not possible a decade ago. Adoption of coherent technology has increased dramatically, driven by rising bandwidth demand and technological advancements in DSPs, silicon photonics (SiP), and integration. Coherent DSP technology will…

When you think of Cisco, you might think we just connect computers or make the Internet run (already in itself a rather large feat). But I am here to tell you that in all my years as a Cisconian, I have seen the impact we have – globally, locally, and even directly within my family. At the end of the day, at this company with heart, connecting people to people is what we’re all about….

Wi-Fi Alliance now requires all new Wi-Fi CERTIFIED devices to support WPA3 security. In 2021 the industry will see greater adoption of WPA3 across more devices, networks, and environments – including sensitive environments like governments and financial institutions. The number of devices connected to the internet, including machines, sensors, and smart home devices is forecast to reach 41.6 billion in the next four years. With the increase in number of devices and Wi-Fi adoption, there…

We all knew this fiscal year ’21 was going to be different, a challenge. What we didn’t know was how many people would show up and stand out, become even more focused on connecting networks, employees, and families, and save, not only lives, but our global economy. We are not finished. There is much to be done, and with Cisco’s mission of positively impacting a billion people by 2025, we are looking for every opportunity…

A few years ago, a large Cisco customer needed to send data from a remote device to the cloud. It was the early days of modern edge computing. To deploy new functionality to remote network devices at that time required building an app that could work with an existing device’s OS and sometimes adding a server or PC. Different operating systems on various types and brands of devices were additional complexities and added workload. Today, thanks to container applications and the acceleration of containerization technology, app hosting is lightyears from where it started.    Here’s a look at what the Cisco IOS XE team dedicated to app hosting has created….

Molly’s sons with a Cisco inspired pumpkin! I will never admit it to them, but I don’t mind picking up after my sons (ages two and six), or sometimes even my husband. And while there is never enough time to do everything as a Cisconian, mom, wife, friend, entrepreneur, and volunteer, I am the type of person who needs to see results, or at least to know that my contributions positively impact others. One of…

Cisco IOS XE―the mighty software stack for all of Cisco’s enterprise networking platforms―is always in a continual state of transformation. We add approximately 700 new features per year, plus bug and security vulnerability fixes.   With 300 million lines of code, Cisco IOS XE is huge. It takes time and careful planning to download an image from www.cisco.com and distribute it to multiple network devices without causing much disruption. That might not be a problem with a smaller company, but for an enterprise with thousands of devices, it’s an ongoing challenge. It requires planning ahead, creating a maintenance window…

A couple of weeks ago, in Part 1 of this ChatOps blog series, you created your first bot. However, it could not do anything… What a shame, huh? Let’s get that fixed asap. Time to take a look at the code required to implement your bot logic. We will be using Python and Flask as they offer a simple and convenient approach you can easily leverage. Please make sure to install Python in your computer and also the Flask library (pip…

Episode 5 of the Cisco Optics Podcast is now posted! See below for episode notes. Cisco Optics Podcast Episode 5 Overcoming the next hurdle to get to 800G pluggable optics, a conversation with Ray Nering, part 1 of 4. What are the industry’s technical experts in pluggable optics thinking about today? What boundaries are the smartest minds are pushing to make the next generation of high-speed optics? In Episode 5, we start a new conversation…

We probably wouldn’t have a Digital Age without silicon. The second most abundant element in the Earth’s crust (oxygen is No. 1), silicon is cheap and has the ability to conduct electricity and/or act as an insulator. Converted into silicon wafers, it powers the computers, smartphones and other electronic devices we use to work and, importantly, to avoid work. So clearly silicon is indispensable. Or maybe not. Our insatiable demand for more and more data,…
