Cisco: Making remote users feel at home on the new enterprise network

When Covid-19 reared its ugly head earlier this year it altered the way millions of corporate workers access enterprise resources.  Now that it’s obvious those changes in many cases are going to be more permanent than originally thought, many customers and vendors are looking to support remote workers in ways not really expected in the past.“The Covid-19 pandemic brought about a huge experiment in widespread remote working,” said Gartner vice president Elisabeth Joyce, of a recent survey of 127 company leaders that found  47% said they intend to allow employees to work remotely full time going forward. “As business leaders plan and execute reopening of their workplaces, they are evaluating more permanent remote working arrangements as a way to meet employee expectations and to build more resilient business operations."To read this article in full, please click here

What is IPv6, and why aren’t we there yet?

For the most part the dire warnings about running out of internet addresses have ceased because, slowly but surely, migration from the world of Internet Protocol Version 4 (IPv4) to IPv6 has begun, and software is in place to prevent the address apocalypse that many were predicting.But before we see where are and where we’re going with IPv6, let’s go back to the early days of internet addressing.[ Related: IPv6 deployment guide + How to plan your migration to IPv6 ] What is IPv6 and why is it important? IPv6 is the latest version of the Internet Protocol, which identifies devices across the internet so they can be located. Every device that uses the internet is identified through its own IP address in order for internet communication to work. In that respect, it’s just like the street addresses and zip codes you need to know in order to mail a letter.To read this article in full, please click here

5G spectrum auctions expected in 2021 after Pentagon gives up frequencies

The U.S. Department of Defense will turn over some of its 5G frequency spectrum in a bid to help U.S. carriers bring commercial 5G services to market faster. 5G resources What is 5G?

Cisco open-source code boosts performance of Kubernetes apps over SD-WAN

Cisco has introduced an open-source project that it says could go a long way toward reducing the manual work involved in optimizing performance of Kubernetes-applications across SD-WANs.Cisco said it launched the Cloud-Native SD-WAN (CN-WAN) project to show how Kubernetes applications can be automatically mapped to SD-WAN with the result that the applications perform better over the WAN.More about SD-WAN: How to buy SD-WAN technology: Key questions to consider when selecting a supplier • How to pick an off-site data-backup method •  SD-Branch: What it is and why you’ll need it • What are the options for security SD-WAN? “In many cases, enterprises deploy an SD-WAN to connect a Kubernetes cluster with users or workloads that consume cloud-native applications. In a typical enterprise, NetOps teams leverage their network expertise to program SD-WAN policies to optimize general connectivity to the Kubernetes hosted applications, with the goal to reduce latency, reduce packet loss, etc.” wrote John Apostolopoulos, vice president and CTO of Cisco’s intent-based networking group in a group blog.To read this article in full, please click here

IBM details next-gen POWER10 processor

IBM on Monday took the wraps off its latest POWER RISC CPU family, optimized for enterprise hybrid-cloud computing and artificial intelligence (AI) inferencing, along with a number of other improvements.Power is the last of the Unix processors from the 1990s, when Sun Microsystems, HP, SGI, and IBM all had competing Unixes and RISC processors to go with them. Unix gave way to Linux and RISC gave way to x86, but IBM holds on.This is IBM's first 7-nanometer processor, and IBM claims it will deliver an up-to-three-times improvement in capacity and processor energy efficiency within the same power envelope as its POWER9 predecessor. The processor comes in a 15-core design (actually 16-cores but one is not used) and allows for single or dual chip models, so IBM can put two processors in the same form factor. Each core can have up to eight threads, and each socket supports up to 4TB of memory.To read this article in full, please click here

Managing process accounting on Linux

Process accounting is a method of recording and summarizing commands and processes. It's an option on Linux systems, but you have to enable it and use a particular command to view the details collected. This post covers the commands involved and offers some suggestions on making the views even more useful.To start, understand that process accounting is different than what you see when running the ps command. It shows details on commands that have completed –- not those that are currently running. It also shows a lot more details than you would see by looking at your users' command history files and keeps all the collected data in a single file on the system.To read this article in full, please click here

How to make sure data that should be backed up gets backed up

There is no sadder moment in the backup world than finding out the file or database you need to restore has never been backed up. Understanding how systems, directories, and databases are included in the backup system is the key to making sure this never happens to you.The first step toward this goal is making sure that servers and services you want backed up are registered with your backup-and-recovery system.[Get regularly scheduled insights by signing up for Network World newsletters.] For example, if you start using a new SaaS such as Salesforce, no backup system will automatically notice that addition and start backing it up for you. If you are fully virtualized on VMware, the systems will automatically notice if you add a new node to the configuration. But if you start using Hyper-V or KVM, no backup system will automatically notice there is a new hypervisor in the data center and start backing it up. And of course your backup system will not notice you installed a new physical server.To read this article in full, please click here

How the network can support zero trust

Simply stated, zero trust calls for verifying every user and device that tries to access the network and enforcing strict access-control and identity management that limits authorized users to accessing only those resources they need to do their jobs.Zero trust is an architecture, so there are many potential solutions available, but this is a look at those that fit in the realm of networking.[Get regularly scheduled insights by signing up for Network World newsletters.] Least privilege One broad principle of zero trust is least privilege, which is granting individuals access to just enough resources to carry out their jobs and nothing more. One way to accomplish this is network segmentation, which breaks the network into unconnected sections based on authentication, trust, user role, and topology. If implemented effectively, it can isolate a host on a segment and minimize its lateral or east–west communications, thereby limiting the "blast radius" of collateral damage if a host is compromised. Because hosts and applications can reach only the limited resources they are authorized to access, segmentation prevents attackers from gaining a foothold into the rest of the network.To read this article in full, please click here

AI system analyzes code similarities, makes progress toward automated coding

With the rapid advances in artificial intelligence (AI), are we getting to the point when computers will be smart enough to write their own code and be done with human coders? New research suggests we might be getting closer to that milestone.Researchers from MIT and Georgia Tech teamed with Intel to develop an AI engine, dubbed Machine Inferred Code Similarity (MISIM), that's designed to analyze software code and determine how it's similar to other code. What's most interesting is the potential for the system to learn what bits of code do, and then use that intelligence to change how software is written. Ultimately, a human could explain what it wants a software program to do, and then a machine programming (MP) system could come up with a coded app to accomplish it.To read this article in full, please click here
