Multicast Routing in AWS

Consider for a moment that you have an application running on a server that needs to push some data out to multiple consumers and that every consumer needs the same copy of the data at the same time. The canonical example is live video. Live audio and stock market data are also common examples. At the re:Invent conference in 2019, AWS announced support for multicast routing in AWS Virtual Private Cloud (VPC). This blog post will provide a walkthrough of configuring and verifying multicast routing in a VPC.

Digging up IP addresses with the Linux dig command

Not unlike nslookup in function, but with a lot more options, the dig command provides information that name servers manage and can be very useful for troubleshooting problems. It’s both simple to use and has lots of useful options.The name “dig” stands for “domain information groper” since domain groping is basically what it does. The amount of information that it provides depends on a series of options that you can use to tailor its output to your needs. Dig can provide a lot of detail or be surprisingly terse.[Get regularly scheduled insights by signing up for Network World newsletters.] Just the IP, please To get just the IP address for a system, add the +short option to your dig command like this:To read this article in full, please click here

Let’s Improve Routing Security at APRICOT 2020

Internet builders in Asia-Pacific get together around this time every year at APRICOT to learn from each other and other leaders from around the world. Routing security will be a key theme, and we will be sharing in multiple sessions why the MANRS initiative is important to the global routing system.

Also called the Asia-Pacific Regional Internet Conference on Operational Technologies, the conference is the largest meeting of the technical community in the region. It draws many of the world’s best Internet engineers, operators, researchers, service providers, and policy enthusiasts from over 50 countries to learn, share, and network.

Held annually, the ten-day meeting consists of workshops, tutorials, and conference sessions, birds-of-a-feather (BoFs) sessions, and peering forums all with the goal of spreading the knowledge needed to run and expand the Internet.

Technical training workshops will run from Feb 12 to 16, and the conference itself from 17 to 21 in Melbourne, Australia.

Our team at the Mutually Agreed Norms for Routing Security (MANRS) initiative will speak at various sessions throughout the conference, including the Resource Public Key Infrastructure (RPKI) Deployathon on 17 February that I will facilitate. I will also be chairing the inaugural APNIC Routing Security/RPKI SIG on 20 February.

Worth Reading: Why Must Systems Be Operated?

Every now and then I find an IT professional claiming we should not be worried about split-brain scenarios because you have redundant links.

I might understand that sentiment coming from software developers, but I also encountered it when discussing stretched clusters or even SDN controllers deployed across multiple data centers.

Finally I found a great analogy you might find useful. A reader of my blog pointed me to the awesome Why Must Systems Be Operated blog post explaining the same problem from the storage perspective, so the next time you might want to use this one: “so you’re saying you don’t need backup because you have RAID disks”. If someone agrees with that, don’t walk away… RUN!

Server sales projected to decline 10% due to coronavirus

Global server sales had been projected to grow by 1.2% compared to the most recent quarter, but the chaos wrought by the coronavirus in China will cause sales to decline 9.8% sequentially, according to DigiTimes Research.DigiTimes is an IT publication based in Taiwan. Its proximity to Taiwanese and Chinese vendors gives it some good sources, but it can also be way off target. However, the signs are piling up that coronavirus is causing some real mayhem.For example, DigiTimes also reported that less than 20% of Chinese factory employees would return to work after an extended Lunar New Year break due to the coronavirus outbreak, and that many components plants in China have decided not to restart production until February 25.To read this article in full, please click here
