5G can make for cost-effective private backhaul

Equipment vendors and carriers have talked a great game about 5G's promise. Its ability to handle the high-density wireless environments created by IoT deployments and provide gigabit speeds to smartphones has been trumpeted from the rooftops. 5G resources What is 5G? Fast wireless technology for enterprises and phones How 5G frequency affects range and speed Private 5G can solve some problems that Wi-Fi can’t Private 5G keeps Whirlpool driverless vehicles rolling CBRS can bring private 5G to enterprises But it's important to realize that the most eye-catching capabilities of 5G technology aren't here yet, as many of them depend on the 5G New Radio (NR) technology operating at high, millimeter-wave frequencies, which isn't yet widely available. Nor are the vast majority of endpoints currently on the market able to communicate on those sorts of networks.To read this article in full, please click here

History of Networking: An African Perspective of the Internet

Dawit Bekele began his journey with the Internet while at college—but on returning to Africa, he discovered there was very little connectivity. While he was not involved in the initial stages of engineering the Internet in Africa, he began as an early user and proponent of connecting his home continent, and is now part of the Internet Society, helping to grow connectivity.

How open networking can make supply chains more resilient

Supply chains are fragile things. They’re a web of suppliers and distributors, of storage and shipping facilities, and of resellers, all working at just the right speeds and with just the right margin of error to keep things flowing smoothly. But any fragile system is inevitably vulnerable to world events.

With the increasing requirement to support remote work, a robust, adaptable network is a business necessity. But it can be a challenge to source the networking equipment you need when global trade is disrupted. Open networking—where you’re not locked into specific network components—gives you many supplier and platform options to choose from, increasing your flexibility to deal with sudden and substantial change.

The lean supply chain

Lean manufacturing has become a common business practice. An IndustryWeek survey in 2016 ranked lean manufacturing systems as one of the most important technological advancements (second only to quality management systems).

Lean companies prioritize efficiency and work to reduce waste. This often means that they don’t stockpile components or keep a large inventory of completed products, which keeps money from being tied up in excess goods or unused warehouse space.

Companies source parts and labor from across the globe in an effort to trim Continue reading

Knowledge Sharing and Meaningful Conversation at InterCommunity 2020: Securing Global Routing

Recently, five routing security experts shared how they’ve been working to protect the Internet from the most common routing threats – by implementing and promoting the actions called for in Mutually Agreed Norms for Routing Security, or MANRS. They were all participants in InterCommunity, which gives the Internet Society community a way to connect for meaningful conversations about the issues that matter most to the Internet.

Want to join the InterCommunity conversation? Become an Internet Society member today!

This session of InterCommunity, “Securing Global Routing,” set out to increase awareness of MANRS, share good routing practices, and encourage more network operators to take the MANRS actions to make the Internet more secure for us all.

The speakers shared their network operations and capacity building knowledge while more than 200 participants participated live in the informative conversation.

Special thanks to Melchior Aelmans of Juniper Networks who moderated the discussion skillfully!

Here’s what the panelists had to say:

Abdul Awal, Bangladesh National DataCentre
Awal spoke about his goals in building technical capacity around Resource Public Key Infrastructure (RPKI) and raising awareness of MANRS principles in South Asia. He also discussed how we can help networks validate their routing Continue reading

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

Unsolicited Multicast: Random Thoughts on the LFN White Paper

A short while back, the Linux Foundation (Networking), or LFN, published a white paper about the open source networking ecosystem. Rather than review the paper, or try to find a single theme, I decided to just write down “random thoughts” as I read through it. This is the (rather experimental) result.

The paper lists five goals of the project which can be reduced to three: reducing costs, increasing operator’s control over the network, and increasing security (by increasing code inspection). One interesting bit is the pairing of cost reduction with increasing control. Increasing control over a network generally means treating it less like an opaque box and more like a disaggregated set of components, each of which can be tuned in some way to improve the fit between network services, network performance, and business requirements. The less a network is an opaque box, however, the more time and effort required to manage it. This only makes sense—tuning a network to perform better requires time and talent, both of which cost money.

The offsetting point here is disaggregation and using open source can save money—although in my experience it never does. Again, running disaggregated software and hardware requires time and talent, Continue reading
