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…

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,…

By Tim Vanevenhoven, Director of Business Development and Strategic Partnerships. As customers return to stores, restaurants, and public venues, companies are increasingly leveraging mobile point-of-service tools to acquire and retain customers and run back-office operations. Whether it’s a mobile point-of-sale terminal, a portable receipt printer, or a wireless inventory barcode scanner, the business-critical roles played by these devices requires always-on network access and always-up application performance. Standard IT troubleshooting and diagnostic tools examine segments of…

Enterprises are increasingly adopting a multitude of applications delivered from the cloud. These applications not only promise to reduce IT costs but to enable key outcomes at scale to ensure business continuity and guaranteed SLAs. Enterprise IT is responsible for the seamless connectivity to these applications and ensuring their security and efficiency while maintaining low TCO. Two recent cloud integrations with the Cisco Catalyst 9000 series switches ― Cisco ThousandEyes and Cisco DNA Spaces ―…

Moving to cloud is an individual journey for every organization. Many companies have taken the hybrid path and are working within multiple clouds. Yet others are still primarily on-prem but want to continue their transition to cloud seamlessly in their own time and at their own pace.  No matter where in the cloud journey an organization is, options and flexibility are essential to being able to address the organization’s unique business requirements. With the increasing number of both managed and unmanaged devices connecting to corporate networks, simplicity and automation play a critical role in how…

  Co-author – Steve Shearer, Chief Scientist, octoScope Contributors – Ming Chong and Santa Chowdhury (octoScope) We are particularly grateful to Nilesh Doshi (Sr. Wireless AP Manager) for his supervision. Servicing many clients that are using small packets with non-Wi-Fi 6 is inefficient because the overheads incurred by the preamble and other mechanisms tend to dominate. OFDMA is ideally suited for this scenario because it divides up the channel and services up to 37 users…
