FCC auctions should be a long-term boost for 5G availability

0:16
As the march towards 5G progresses, it’s apparent that more spectrum will be needed to fully enable it as a service, and the Federal Communications Commission has clearly taken the message to heart. The FCC recently finished auctioning off priority-access licenses for Citizen’s Broadband Radio Service (CBRS) spectrum for 5G, representing 70MHz swath of new bandwidth within the 3.5GHz band. It took in $4.58 billion and is one of several such auctions in recent years aimed at freeing up more ch...

BrandPost: Defining True Flexibility for SD-WAN

20:25
SD-WAN was initially designed as a more flexible and cost-effective solution for connecting branch offices to cloud resources and the core network. And that is still the primary way it is deployed. Replacing static and costly MPLS connections and edge routers with a system that can manage and optimize connections and application performance has helped millions of organizations deploy a more robust and adaptable WAN strategy. The right SD-WAN solution can do so much more. But far too many vend...

VMware plan disaggregates servers; offloads network virtualization and security

20:25
VMware is continuing its effort to remake the data center, cloud and edge to handle the distributed workloads and applications of the future. At its virtual VMworld 2020 event the company previewed a new architecture called Project Monterey that goes a long way toward melding bare-metal servers, graphics processing units (GPUs), field programmable gate arrays (FPGAs), network interface cards (NICs) and security into a large-scale virtualized environment. Monterey would extend VMware Cloud Fou...

BrandPost: The Quest for Agility

19:05
The widespread disruptions caused by Covid-19 are redefining business agility. It’s no longer just about pursuing new opportunities, building code quickly, or ensuring disaster recovery. With millions of workers booted out of their offices and reliant on home Internet connections to stay connected and productive, the very nature of agility has taken on new dimensions as people and organizations discovered how well, or not, they were able to respond to unanticipated challenges. That has a lot ...

Should you be concerned about the Windows XP leak?

11:25
Reports hit the Web last week that the Windows XP source code has been leaked and posted to 4chan, one of the seediest boards not on the dark web. A link to a 42.9GB file was posted but quickly scrolled off. 4chan does not archive its posts so once the message scrolled off it was gone, but the link is getting around in other ways. The code is being hosted by Mega, a file-sharing service with its own dubious past. Reports from other sites say the code is legitimate. Microsoft has only said “We...

Streaming telemetry challenges SNMP in large, complex networks

11:25
Network telemetry is far from new, but its importance is growing as data volume and network size relentlessly snowball. Streaming network telemetry gathers operational data from various network devices, combines the information, and then forwards it for inspection and study. Growing scale and the increasing use of automation in next-generation enterprise networks require a modern, more efficient approach to network data capture and analytics, says Bo Lane, vice president of global engineering...

BrandPost: New Value Together: Make Any Room a Data Centre

28.September
This is a fully connected, intelligent world, where data is a key asset. As services expand, the volume of global data will increase from 44 ZB in 2020 to 180 ZB by 2025. Data centres are increasingly important to the global digital economy. Digital transformation adds pressure to public sector, along with finance, energy, and transportation industries, which are also coping with the uncertaint...

How to view information on your Linux devices with lshw

28.September
While far from being one of the first 50 Linux commands anyone learns, the lshw command (read as “ls hardware”) can provide a lot of useful details on your system’s hardware. It extracts details—maybe quite a few more than you knew were available—in a format that is reasonably easy to digest. Given descriptions, logical (device) names, sizes, etc., you are likely to appreciate how much detail you can access. This post examines the information that lshw provides with a particular focus on disk...

Government cybersecurity agency warns of Windows Server exploit

25.September
The federal government's Cybersecurity and Infrastructure Security Agency (CISA) has issued a rare emergency directive to federal government agencies to roll out a Windows Server patch within days, an indication of the severity of the exploit. The directive was issued on September 18, and agencies were given four days to apply the security update. It demands that executive agencies take "immediate and emergency action" to patch CVE-2020-1472 , issued August 11. The vulnerability is in Microso...

Cisco turns out security patches 25 high-threat flaws for IOS, IOS XE

25.September
If you are a security admin with lots of systems running Cisco IOS and IOS XE software today is decidedly not your day. Cisco this week posted 25 “High” rated security advisories that stem from 34 vulnerabilities the company suggests should be fixed as soon as possible. The vulnerabilities impact a wide-range of Cisco gear as IOS and IOS XE are the company’s most widely used operating systems. The warnings affect firewalls, wireless access points and switches. For example, one of the highest ...

MemVerge ships software-defined persistent memory software

25.September
Big Memory software startup MemVerge launched its Memory Machine software designed to t urn DRAM and Intel Optane persistent memory into a software-defined memory pool , bringing DRAM performance to persistent memory (PMEM). For some use cases, SSDs just aren’t fast enough. “Despite all the great advances in storage, the latency difference between memory and storage remains at more than three orders of magnitude, making this data movement inefficient,” said Alper Ilkbahar, vice president and ...

What is a virtual machine, and why are they so useful?

24.September
Many of today’s cutting-edge technologies such as cloud computing, edge computing and microservices owe their start to the concept of the virtual machine—separating operating systems and software instances from a physical computer. What is a virtual machine? At its base level, a virtual machine (VM) is software that runs programs or applications without being tied to a physical machine. In a VM instance, one or more guest machines can run on a physical host computer. Each VM has its own opera...

Could human organs join networks?

24.September
The idea of integrating computer networks and the human body is driving research in a number of areas. Recently, two teams of researchers shared their respective projects, which explore how biological cells might become networked and how electronics could become directly integrated with human tissue. Both presentations were part of the American Chemical Society's (ACS) Fall 2020 Virtual Meeting & Expo. The first presentation, conducted by a team at the University of Maryland, is focused on co...

Vendors lengthen the range of 5G millimeter-wave transmissions

23.September
Two wireless vendors say they have collaborated to significantly extend the useful range of millimeter-wave 5G transmissions beyond what had been widely considered its limits. Qualcomm and Ericsson have worked together in separate trials with two other companies to boost that distance from less than a mile (1.6km) to 3.8km in one case and to 5km-plus in the other , the companies claim.

Still not dead: The mainframe hangs on, sustained by Linux and hybrid cloud

23.September
The mainframe has been declared “dead”, “morphed” and “transformed” so many times over the years sometimes it’s sometimes hard to believe the Big Iron still has an identity in the enterprise world. But clearly it does and in a major way, too. Take recent news as an example: According to IBM, 75% of the top 20 global banks are running the newest z15 mainframe, and the IBM Systems Group reported a 68% gain in Q2 IBM Z revenue year-over-year.
