With that in mind, I want to dissect the…

High-tech vendors continue to battle supply-chain problems and higher costs brought on by the current semiconductor shortage, according to statements made in the most recent round of earnings calls. As Network World reported in May, COVID-19 triggered an explosion of the global remote workforce, which created extraordinary demand for new tech gear.

You may have seen us touting our new generation of 100G SMF pluggable optics, called “Single-Lambda 100G“. The last product we introduced was the 100G LR, which provides a 10km reach. We’ve now finalized the portfolio with the 100G ER-Lite. The reach of ER-Lite is 25km. So it can support links between a company’s campuses, between campuses of a data center cluster, and fronthaul or backhaul links in a wireless network. It’s great for when…

If you’ve been attacked by ransomware, a fully automated, high-speed disaster recovery is the way to successfully avoid paying the ransom. Recovery is the second step in the two-step process after getting rid of the malware as described here. There are three ways to affect a disaster recovery after a ransomware attack: a traditional recovery, an image-based recovery, or a cloud-based recovery. But the only way for most environments to afford automating a large-scale recovery…

My 6-year-old daughter Kaleigh and I have daddy daughter dates every Saturday where we go to karate together. It’s kind of a long drive, 1.5 hours each way, but we enjoy the time together. During a recent drive, my daughter was quietly looking out the window and said, “Daddy, I want to be an engineer and work at Cisco like you do!” Cue the teary eyes! I, of course, told her, “Kaleigh, you can do…

In order to achieve a resilient network, it is important to maintain high availability not only in control plane, but also at the data plane for traffic to flow smoothly, without any disruptions. In the event of unavailability of control plane, which governs and manages the data plane traffic, the whole WAN infrastructure and subsequent site traffic can go down, causing huge outages. The SD-WAN solution should be intelligent enough to not only ensure continuous data plane operation, but also to provide an optimized path for the application traffic for enhanced…
