Cisco pushes silicon photonics for enterprise, webscale networking

Cisco said it's closed its deal to buy optical-semiconductor firm Luxtera for $660 million, bringing it the advanced optical technology customers will need for speed and throughput for future data-center and webscale networks.When Cisco announced the deal in December, Rob Salvagno, Cisco's vice president of Corporate Business Development, said, “As system port capacity increases from 100GbE to 400GbE and beyond, optics plays an increasingly important role in addressing network infrastructure constraints, particularly density and power requirements.”To read this article in full, please click here

Dell CTO talks modern data centers, the edge, and digital disruption

Dell’s CTO has laid out the company’s vision of where enterprise technology is headed in 2019, and it’s not what people were predicting a few years ago.Gone is the talk of the demise of the data center. Instead, the data center is being repurposed, and some of its tasks are being moved to the edge, said Robert Hormuth, CTO and vice president of Dell EMC Server Infrastructure Solutions. This, he said, is a time to be disruptive before your competition.[ Read also: Edge computing best practices and Edge computing is the place to address a host of IoT security concerns | Get regularly scheduled insights: Sign up for Network World newsletters ] In a recent blog post, Hormuth said IT must be the enabler of the transformational journey for IT. “Businesses must transform and embrace the digital world, or get run over by a new, more agile competitor with a new business model benefiting from advanced technologies like data analytics, AI, ML, and DL. No business is safe from the wave of digital disruption,” he wrote.To read this article in full, please click here

Last Month in Internet Intelligence: January 2019

This post is presented in conjunction with The Internet Society.

During the second half of 2018, the causes of significant Internet disruptions observed through the Oracle Internet Intelligence Map could be clustered into a few overarching areas: government-directed, cable problems, power outages, distributed denial of service (DDoS) attacks, and general technical issues. Little changed heading into 2019, with two new government-directed Internet disruptions observed in Africa, alongside disruptions caused by fiber cuts and other network issues that impacted a number of countries around the world.

Government Directed

Initially covered in last month’s overview, the Internet disruption in the Democratic Republic of Congo continued into January, lasting through the third week of the month. Government authorities reportedly cut off Internet access in the country in December to prevent “rumor mongering” in the run-up to presidential elections.

An attempted military coup in Gabon led to a day-long Internet disruption in the country. The disruption started just after 07:00 UTC on January 7, as seen in the figure below, which shows clear declines in the Traceroute Completion Ratio and BGP Routes metrics, as well as a disruption to the usual diurnal pattern seen in the DNS Query Rate metric. Although the coup Continue reading

Moore’s Law has underwritten a remarkable period of growth and stability for the computer industry. The doubling of transistor density at a predictable cadence has fueled not only five decades of increased processor performance, but also the rise of the general-purpose computing model. However, according to a pair of researchers at MIT and Aachen University, that’s all coming to an end. —Michael Feldman
