Microburst: Update on the HTML Home Network Diagram

Moving Packets - Microburst

 

Last week I published an article called Making a Clickable HTML Network Diagram using OmniGraffle. One of the questions I was asked was whether I’d tried doing the same in draw.io or Gliffy. I have not, although I do use Gliffy a fair amount, and I have dabbled with draw.io.

Thankfully, Keith Miller (@packetologist) is on hand to provide the answer! Keith has put together an article mirroring a similar process using the free (and platform-agnostic) draw.io. Definitely worth a read, and a great example of a free tool making our lives way easier.

Where’s Russ?

This is my second week of PhD seminars this fall—the only time in this program I intend to take two seminars back to back. One of the two was, in fact, very deep philosophy, so I was pretty taxed trying to pull the material together.

At the same time, the book has passed through technical review, and is now in author review. I hope it soon be in proofs. The combination of these two things, the book and the PhD work, along with multiple other things, is what caused me to call a pause in blogging for these two weeks. The date to watch is the 29th of December. It might be released earlier, but it is hard to tell right now. I will do a post a little later this week describing the book for those who are interested.

Tonight (Monday) I will be recording a new Network Collective show on the Intermediate System to Intermediate System (IS-IS) protocol, and we have a long list of History of Networking guests to bring on. The history material has turned out to be absolutely fascinating; I am thankful we have the connections available, and the recording venue, and someone Continue reading

What will programming look like in the future?

 

Maybe programming will look something like the above video. Humans and AIs working together to produce software better than either can separately.

The computer as a creative agent, working in tandem with a human partner, to produce software, in a beautiful act of co-creation.

The alternative vision—The Coming Software Apocalypse—is a dead end. Better requirements and better tools have already been tried and found wanting. Requirements are a trap. They don't work. Requirements are no less complex and undiscoverable than code. Tools are another trap. Tools are just code that encode an inflexible solution to a problem that's already been solved.

Admittedly, I'm cheating. I have no idea how any of this will work, but here are the seeds of how it has already started:

Here's what we do know: neither tools or requirements are a silver bullet, they are a method of incrementally improving software quality. Software production quantity is not increased at all.

What we need is a manufacturing process that puts software production on an exponential curve. The only conceivable tool we have at Continue reading

Worth Reading: Open Source Licenses

Today, the GPL license that Stallman pioneered is in its third version (GNU GPLv3) and is only one of several dozen types of open source licenses. The Open Source Initiative, an organization founded in 1998 to promote open source software and normalize the use of the term, has approved more than 80 open source licenses. These 80 licenses generally fall into one of two categories: permissive licenses and copyleft licenses. —Heather Meeker @OpenSource

First Practical Workshop on IoT to Increase Awareness and Interest in Ethiopian Universities

The Department of Computer Science College of Natural Sciences of the Addis Ababa University (AAU), in collaboration with the Internet Society and International Center for Theoretical Physics (ICTP) successfully concluded the 1st practical workshop in Ethiopia on Internet of Things (IoT). The workshop, which took place in Addis Ababa, Ethiopia, from 23-29 September 2017 aimed at increasing the awareness and interest of IoT amongst Universities in Ethiopia and in the long run enhance the understanding and involvement of Africans in IoT standardization at the Internet Engineering Task Force (IETF).

The workshop came at an important crossroad as we are at the beginning of a new revolution, witnessing our pots and cups turned to be part of the computing world. The wrist watch no longer tells us the “time” only, but also a lot more information – from the status of the weather to our health. Our “things” can be enabled to compute and even communicate to one another; and this takes us to new mode of computation known as IoT.

Dawit Bekele, Director of the African regional bureau of Internet Society reflected on this issue saying that “the potential of IoT in all Continue reading

IDG Contributor Network: 3 ways machine learning is revolutionizing IoT

Few things have propelled the IoT’s dizzying growth in recent years as much as machine learning and the innovators who are pushing it. Independent, intelligent machines that can comb through data to make their own decisions are, to some, the only reason such phenomenon as the IoT can exist in the first place. So what are the top three ways in which machine learning has and will shape the IoT?Whether it’s inspiring human creativity, surpassing human efficiency, or paving the way for even newer technologies to themselves break through and reshape the IoT, machine learning is the fuel that’s driving the IoT forward into the 21st century.

IDG Contributor Network: Not all information is created equal: Unlocking the huge potential of smart data

The amount of data being created today is expected to increase ten-fold in less than a decade, it’s also anticipated that enterprises will produce around 60% of global data by 2025[1]. However, while the amount of data may be growing exponentially, the intelligence gleaned from it is not. Instead, companies can be subject to a barrage of unstructured data delivered at high velocity from a variety of different sources with limited ability to convert it into actionable insight. As a result, enterprises risk useful information getting lost amidst the sheer volume of noise.This is set to be further compounded by the widespread adoption of IoT technologies in both consumer and enterprise markets. The proliferation of IoT sensors, mobile devices and digital services, combined with advent in big data technologies and broadband networks increase the volume, velocity and variety of data traversing the connected world. This means that businesses that collect relevant data that flows through their corporate networks and the connected world are sitting on an abundance of data, which will only increase. Mission contextual analysis of this data can provide invaluable insight to corporations in a variety of areas and improve business outcomes. For example, gleaning insight Continue reading

Task List Tracker for the Mac (DIY Version)

As a Mac user, how do you keep track of the tasks you need to complete? I find myself swamped in things that need doing and every day more things get added to my list. The problem is, in the past I’ve relied too much on my memory to keep track of what I need to do, and I’m sadly aware that there are more things on my task list than I can keep track of, and all too frequently I get into work and think “What was I going to do this morning? I’m sure there was something high priority, but…”

It should be easy, you’d think, to maintain a list of tasks, assign some kind of priority, and have that list readily accessible while using my computer. I suspect there’s an app (indeed, that there are many apps) for that, but while I have tried a few, somehow I’ve not managed to integrate them into my daily workflow. I spoke to a colleague about this, and he said that he keeps a text file on his Desktop listing all his open tasks, and he updates it as needed. If it works for him, maybe it would work for Continue reading

How to avoid ‘the biggest rip-off in networking’

Old habits die hard, especially when it comes to buying network gear and accessories based on long-standing procurement practices. While it may seem easier to sustain the status quo, doing so can expose you to undue costs created by manufacturer price-gouging practices.Case in point: Optical transceivers, which Gartner says accounts for 10 to 15 percent of enterprise network capital spending. This may not seem like a big budget buster, but huge markups on optics is the subject of a new Gartner report, entitled “How to Avoid the Biggest Rip-Off in Networking.”To read this article in full or to leave a comment, please click here

Solving the Problem in the Right Place

Sometimes I have this weird feeling that I’m the only loony in town desperately preaching against the stupidities heaped upon infrastructure, so it’s really nice when I find a fellow lost soul. This is what another senior networking engineer sent me:

I'm belonging to a small group of people who are thinking that the source of the problem are the apps and the associated business/security rules: their nature, their complexity, their lifecycle...

Sounds familiar (I probably wrote a few blog posts on this topic in the past), and it only got better.

Deploy360 @ ENOG 14

Our colleague Jan Žorž from the Deploy360 team will be presenting at the 14th Eurasia Network Operators Groups (ENOG 14) on 9-10 October 2017 in Minsk, Belarus. This is being preceded by workshops on Best Practices in IPv6 BGP and DNSSEC Operations.

Jan will be talking about his real life experiences with NAT64/DNS64 and will be demonstrating the NAT64check tool on Monday evening (17.00-18.15). Following after his talk is a BoF on the Internet-of-Things (18.30-19.30), which is also sure to include discussions about the importance of IPv6 to scale the expected many billions of devices in future.

We’d also like to highlight the Cloudflare update on IPv6, DNS, DNSSEC, CA certs from Martin Levy (Cloudflare) on the Tuesday (10.00-11.30), who seems to be managing to cover just about all the Deploy360 topics in one talk. And for routing security, Kirill Malevanov, (Selectel) will be discussing his experiences of IPv4 prefix hijacking.

Support New Ways of Working To Connect The World

The World Telecommunications Conference (WTDC) begins today. This is a key moment to remind the world that together we can shape a digital future that puts humanity at the heart of the Internet.  But to do this we need your help.

Help send the message that to close the digital divide we’ll need new ways of working, new ways of thinking, and new policies support it all.

Much of what we are speaking on at WTDC serve as real-world examples of the kinds of things we need policy and decision makers to support – community networking being a key focus.

We will keep you up-to-date on what is happening and what we need to do next the conference.

Here’s how you can help:

BGP ADD-PATH – Summary

Hi,

First things first, I have been getting a lot of requests to upload the lab’s which i illustrate as is, so i shall be uploading them to a Github page with initial and final-configs and Instead of vagrant i shall be using EVE-NG as a tool so that you guys can import them easily.

https://github.com/r2079/JDC

Going through Fabric-Path and CLOS concepts, got myself started with 3 Stage Clos and as a part of understanding it, discovered something.

Why –  To make sure Servers at one end have equal cost path to the servers-at other end, at scale the spine accordingly optimizing the CAPEX.

Simple words, in the below topology, we need to make sure that R6 has equal cost to R7 and vice-versa.

 

Protocols and setup

-> OSPF for the entire domain and Ibgp to peer between RR (R2) and all other loopbacks, we use OSPF so that Ibgp peering will be over Loopback and also for load-balancing protocol Next-hops

-> Default routes on R6 and R7, load-balance (per-packet) on all-routers (where technically required)

-> R3 AND R4,R5 has static back to loopbacks of R6 and R7 respectively, advertising them into OSPF will defeat the purpose obviously Continue reading

Introduction to DHCP (Dynamic host configuration protocol)

 Today I am going to talk about the most interesting topic named as DHCP. I knew lot of you guys already knew about the DHCP and how it works in the real network environment but some of you are the beginners in the field of networking and this is why it is one of the most important topic for them.

Why we use the DHCP server and what is the purpose of the DHCP ?

Well Routers, servers, other key nodes require specific or static IP address and Clients can use an IP from a pool of available addresses. Minimum host configuration for Internet:
  • IP address
  • Subnet mask
  • Default gateway
  • DNS server IP

DHCP allows network administrator to assign a pool of available IP addresses for clients with additional configuration information such as default gateway, DNS IP, WINS IP, domain names
Addresses are leased, Cisco default is 24 hours

Fig 1.1- DHCP Server


DHCP process
·      Client boots up, sends a DHCPDISCOVER broadcast
·      All available DHCP servers respond with DHCPOFFER containing proposed IP address, lease time, DNS IP; server checks that IP offered is not in use before making the offer by issuing a default 2 pings
