Why Is MPLS Segment Routing Better than LDP?

A while ago I made a statement along the lines of “MPLS segment routing is the best thing that happened to MPLS control plane in a decade”. Obviously some MPLS-focused engineers disagree with that and a few years ago I decided to write a lengthy blog post explaining the differences between using MPLS SR with IGP (or BGP) versus more traditional IGP+LDP approach.

Obviously, I wasn’t making any progress on that front, so the only way forward was to record a short video on the topic which didn’t work well either because the end-result was a set of three videos (available with free or paid ipSpace.net subscription).

Why blockchain (might be) coming to an IoT implementation near you

Companies have found that IoT partners well with a host of other popular enterprise computing technologies of late, and blockchain – the innovative system of distributed trust most famous for underpinning cryptocurrencies – is no exception. Yet while the two phenomena can be complementary in certain circumstances, those expecting an explosion of blockchain-enabled IoT technologies probably shouldn’t hold their breath.Blockchain technology can be counter-intuitive to understand at a basic level, but it’s probably best thought of as a sort of distributed ledger keeping track of various transactions. Every “block” on the chain contains transactional records or other data to be secured against tampering, and is linked to the previous one by a cryptographic hash, which means that any tampering with the block will invalidate that connection. The nodes – which can be largely anything with a CPU in it – communicate via a decentralized, peer-to-peer network to share data and ensure the validity of the data in the chain.To read this article in full, please click here

RIP Up Your Dynamic Routing With OSPF

What is dynamic routing? Why is Routing Information Protocol (RIP) horrible, and Open Shortest Path First (OSPF) ever so slightly less horrible? How does Linux handle OSPF, and what advantages does it bring over traditional networking gear in complex, intent-based, infrastructure-as-code environments?

RIP and OSPF are Interior Gateway Protocols (IGPs). IGPs are protocols designed to allow network routers and switches within an organization’s internal network to dynamically reconfigure the network to respond to changes. These changes may include the addition or removal of network equipment or network links between network devices.

The purpose of IGPs is to tell networking equipment which devices live where. While devices that are part of the same subnet can find one another, they require a router to communicate with devices on other subnets. Routers and switches keep routing tables of which devices are on which physical interface, and VLAN. These routing tables allow each device to know where to send a packet to reach a given system, and whether or not that packet needs to be encapsulated or tagged.

IGPs allow routers and switches to exchange some or all of their routing tables so that other devices within the network fabric know where to send Continue reading

BrandPost: Edge Computing is Key to Meeting Digital Transformation Demands – and Partnerships Can Help Deliver Them

Organizations in virtually every vertical industry are undergoing a digital transformation in an attempt to take advantage of edge computing technology to make their businesses more efficient, innovative and profitable. In the process, they’re coming face to face with challenges ranging from time to market to reliability of IT infrastructure.It’s a complex problem, especially when you consider the scope of what digital transformation entails. “Digital transformation is not simply a list of IT projects, it involves completely rethinking how an organization uses technology to pursue new revenue streams, products, services, and business models,” as the research firm IDC says.To read this article in full, please click here

IPv6 Buzz 023: How State Task Forces Drive IPv6 Adoption

State and regional IPv6 task forces advocate for IPv6 adoption by state governments and the private sector, and educate engineers. In today's episode we chat with George Usi, the Co-Chair of the California IPv6 Task Force to learn more about the task force's goals and what it's achieved to date.

The post IPv6 Buzz 023: How State Task Forces Drive IPv6 Adoption appeared first on Packet Pushers.

Intel formally launches Optane for data center memory caching

As part of its massive data center event on Tuesday, Intel formally launched the Optane persistent memory product line. It had been out for a while, but the current generation of Xeon server processors could not fully utilize it. The new Xeon 8200 and 9200 lines take full advantage of it.And since Optane is an Intel product (co-developed with Micron), that means AMD and Arm server processors are out of luck.As I have stated in the past, Optane DC Persistent Memory uses 3D Xpoint memory technology that Intel developed with Micron Technology. 3D Xpoint is a non-volatile memory type that is much faster than solid-state drives (SSD), almost at the speed of DRAM, but it has the persistence of NAND flash.To read this article in full, please click here

2019 African Chapters Advocacy Meeting and Internet of Things Security Engagement Workshop

When and where

The 2019 African Chapters Advocacy Meeting will take place from 8-11 April 2019 in Addis Ababa, Ethiopia alongside an Internet of Things (IoT) Security and Privacy Engagement Workshop with the Africa Union Commission (AUC), the Africa Telecommunication Union (ATU), the Regional Economic Commissions (RECs), and other partners.

Why we are doing this

In 2019, the Chapter workshops/Advocacy meetings are our main vehicle to mobilize, strengthen, and engage our Chapters and SIGs around our 2019/2020 focus areas and initiatives. We believe that these meetings represent a unique opportunity to define concrete roles for our Chapters/SIGs to work with us on our global initiatives, and create local impact: “Think global, act local.” It is an opportunity to collect inputs from our regional community for future planning and priorities: “From Local to Global.”

How we are doing it

The Chapters meeting, which will mobilize, empower, and engage 30 fellows from 26 Internet Society African chapters and one global SIG to advance the Internet Society 2019 work in the Africa region with a special focus on “Building Trust” (IoT Security Campaign, Privacy & Personal Data Protection, Encryption, User Trust, and Internet Restrictions).

This meeting is also an Continue reading
