Open Source Routing: A Comparison

I have been getting more interested in open-source networking software, and I figured it was time to write a post comparing some of the more popular open source projects in this space.

Not only do we have several options (which hasn’t always been the case) for running routing protocols in FOSS, but we also have a variety of use cases that are increasing in popularity (using BGP for SDN-type purposes, not just to do internet peering). So isn’t an idea limited to enthusiasts who like to spin their own router - this kind of software has very interesting large-scale applications as well.

This won’t be a comprehensive list, just the top three that I’ve been looking into. I also won’t be going into too much detail on how to set all this software up - I’m saving that for a follow-up post.

Quagga

Quagga is at the top of this list primarily because from my perspective, it is the most well-known. It is best to think of Quagga as a collection of smaller daemons, each with a specific task. This task may be to run a routing protocol like OSPF or BGP, or it may be something else.

Programming an ACI Fabric

By now, you’ve probably heard of Cisco’s Software Defined Networking (SDN) solution that is centered around ACI, or the Application Centric Infrastructure. Like most SDN platforms, a key component is the controller otherwise known as the Application Policy Infrastructure Controller (APIC) in the case of ACI. The APIC provides a single pane of glass that centralizes policy, configuration, and monitoring of the complete fabric. It also more importantly exposes the complete system via an object oriented REST API, which is what we’ll look at in this post.

By itself, ACI reduces the number of touch points in the network. This is no different than any other controller-based network that exists today and is a great step in the right direction. We can then honestly say SDN simplifies operations.

The issue is if you don’t have something else driving ACI, or any other SDN solution for that matter, it could take a large number clicks within the UI to configure a new tenant, application, or whatever is being configured. This is error prone as we all know it’s pretty easy to fat finger something! Because of this, it still makes total sense to automate network fabrics even if it’s not for Continue reading

Microsoft app store gets a spring clean before Windows 10 launch

Microsoft is cleaning house in the Windows Store, enacting policies that could see some apps removed as it tries to reduce clutter and ensure fair pricing ahead of the Windows 10 launch later this year.The new policies, designed to make it easier for users to find quality apps, will also clamp down on developers who abuse keywords to game the Store’s search results.First off, Microsoft wants to ensure users can distinguish between different apps, which means developers will need to use icons that accurately reflect what a program does, and that aren’t too similar to other app icons in the store. The same rules will apply to application titles, and to application functionality.To read this article in full or to leave a comment, please click here

FCC ruling could bolster robocall battle

The Federal Communications Commission could soon clear a path to help in the ongoing battle to fight unwanted and in many cases illegal robocalls and text messages.FCC Chairman Tom Wheeler is proposing a number of changes that the FCC says would “close loopholes and strengthen consumer protections already on the books,” such as the widely used Do-Not-Call Registry. The FCC proposals were in response to industry players who sought clarity on how the Commission enforces the Telephone Consumer Protection Act (TCPA)."The FCC wants to make it clear: Telephone companies can – and in fact should – offer consumers robocall-blocking tools," FCC Chairman Tom Wheeler said in a blog post. In the past some carriers we concerned that blocking automated calls could be construed as violations of the TCPA that requires them to ensure that all calls placed over their networks reach their intended recipients.To read this article in full or to leave a comment, please click here

How to prevent the new Messages bug from crashing your iPhone

A bug in iOS 8 turns a string of Unicode characters into a phone-crashing catastrophe.If you receive a message with the characters, either as an iMessage or an SMS text from contacts on other platforms, your iPhone will crash—but only if you open it. If you receive a notification with the message on your lock screen, your phone will either reboot or lock you out of Messages altogether.MORE: iPhone 7 Rumor RollupThe bug doesn’t actually generate the message—some prankster with your phone number has to actually send the code to you. Let’s hope your friends aren’t jerks. If one of your contacts does send you a malicious message, its effects can be reversed with a follow-up message—or you can send yourself the fix from your Mac by replying to the original string in Messages on OS X, according to The Verge. (The bug only affects iPhones, iPads, and Apple Watches.)To read this article in full or to leave a comment, please click here

IDG Contributor Network: Successful 400 Gbps trials open the door for faster fiber

We've been hearing about speed trials over fiber for years. In 2009, researchers in Denmark were the first to beat the one-terabit mark. For comparison, today's commercial fiber usually runs at 100 gigabits per second.This year's real-world tests, by switch-maker Alcatel-Lucent over existing long-distance fiber, have obtained 400 gigabits per second, or 50 gigabytes in one second.That's especially good because it's real-world and four times better than the current, normally available pipes.Bits are used to measure rate of transfer, and bytes to measure capacity, by the way.To read this article in full or to leave a comment, please click here

An insider’s guide to the private IPv4 market

We’ve been hearing about the impending depletion of IPv4 addresses for years, but that day is finally upon us -- the free supply of IPv4 numbers in North America will be completely gone within a month or two.However, as the world slowly transitions to IPv6, there’s no cause for alarm. A significant quantity of unused, previously allocated IPv4 numbers are readily available for re-distribution to IP network operators that need them. And an active private market for IPv4 addresses has emerged to allow companies with these excess IPv4 numbers to sell them to those in need.+ ALSO ON NETWORK WORLD Infographic: IPv4 vs IPv6 +To read this article in full or to leave a comment, please click here

Senate to return early to debate phone dragnet

The U.S. Senate will return early from a week-long recess in a last-ditch effort to extend provisions of the Patriot Act that the National Security Agency have used to collect millions of domestic telephone records over the past nine years.The Senate is scheduled to resume debating whether to extend or amend Section 215 of the Patriot at 4 p.m. ET Sunday, hours before that part of the counterterrorism law is due to expire. The Senate was previously scheduled to return from an extended Memorial Day break on Monday, but Section 215 of the Patriot Act expires at 12:01 a.m. that day.It’s unclear what direction the Senate debate will take. As of Wednesday morning, Senate Majority Leader Mitch McConnell hadn’t announced what votes will be taken Sunday evening.To read this article in full or to leave a comment, please click here
