BrandPost: Irresistible Appeal of Open Source

The telecom industry is racing toward a software-defined networking (SDN) world, but needs to go beyond traditional cooperation on standards to actually sharing software code, in order to keep pace with innovation.Telecom companies have always cooperated in development of standards. It’s essential for interoperability – otherwise each company’s customers would only be able to interact with its other customers. But there’s a difference between agreeing on standards and sharing software.“The telecommunications space has conventionally used proprietary hardware and software to deploy solutions from various vendors,” writes RCR Wireless staffer Nathan Cranford. “Using multiple vendors enabled telecom operators to open source some network functions, but not to the extent usually fastened to open source software.” But, he contends, “Open source software is indispensable to a faster, more malleable communications network.”To read this article in full, please click here

New Design on www.ipSpace.net

One of my readers sent me a polite email a while ago saying “your site is becoming like $majorVendor’s web site – every corner looks completely different based on when you made it”

The worst part is that he was right, so I spent the last two weeks as a website janitor, mopping up broken markup, fixing CSS cracks, polishing old texts…

BGP in 2017

This is a report on the experience with the Internet's inter-domain routing system over the past year, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection fabric of the Internet.

Salt Overview

Salt is open source software for infrastructure automation. Salt was initially an agent based system but the team have since implemented an ssh based connector for devices that do not support or have the ability to install an agent. This agent/agentless feature give you the ability...continue reading

MC-LAG

MC-Lag

 

Everyone  mostly know what MC-Lag does, for the benefit its a variant of LAG where the Down stream Devices share LAG interface on two Physical devices instead of One, I know its confusing let see a  sample topology

 

 

Vqfx1 will see the upstream as 1 ae1 instead of two different VMX devices, this has its own advantage and the entire discussion is something out of scope of this blog post.

 

Blog Post Goal – Demonstrate MC-Lag on VMX and Quickly highlight the options Common and different in MC-LAG, a ready reference for someone going for an exam or a implementation.

 

Take-Away’s

-> ICCP is the protocol between the nodes

 

  • Uses TCP/IP to replicates control plane and forwarding traffic between peers
  • One stand-by and one active (active responsible status control)
  • ICCP messages exchange configuration information to ensure both peers use correct LACP Parameters
  • ICL-PL (interface between Mx1 and Mx2 ex) supports Multiple MC-Lag Between the peers so its recommended to be a AE.

 

-> ICL-PL HA

 

  • A Keep-alive message is exchanged between MC-LAG peers which is recommended to be the management connection
  • If ICL-PL fails, keep alive is still through the management Continue reading

VMware Cloud on AWS with NSX: Communicating with Native AWS Resources

If you haven’t already, please read my prior two blogs on VMware Cloud on AWS: VMware SDDC with NSX Expands to AWS and VMware Cloud on AWS with NSX – Connecting SDDCs Across Different AWS Regions; also posted on my personal blog at humairahmed.com. The prior blogs provide a good intro and information of some of the functionality and advantages of the service. In this blog post I expand the discussion to the advantages of VMware Cloud on AWS being able to communicate with native AWS resources. This is something that would be desired if you have native AWS EC2 instances you want VMware Cloud on AWS workloads to communicate with or if you want to leverage other native AWS services like AWS S3 VPC Endpoint or RDS.

How VMware’s vSAN provides the storage component for a hyper-converged data center.

VMware's vSAN (virtual SAN) architecture is designed to be a significant step into software-defined-computing, where the vSAN component is responsible for providing software-defined storage.Previously, systems architecture was one server containing its own compute, operating system, networking and storage. Virtualization abstracted this so that more than one OS could run per server, if still bound by captive network functionality, and storage.+See our review of vSAN 6.6+What is hyper-convergence? Hyper-convergence is the ability to abstract all of the components, be it the OS, storage, the network relationships a system has, and so forth. It’s the foundation of the software-defined-datacenter, distributed yet converged into a workload unit.To read this article in full, please click here

Keeping your GDPR Resolutions

Keeping your GDPR Resolutions

For many of us, a New Year brings a renewed commitment to eat better, exercise regularly, and read more (especially the Cloudflare blog). But as we enter 2018, there is a unique and significant new commitment approaching -- protecting personal data and complying with the European Union’s (EU) General Data Protection Regulation (GDPR).

As many of you know by now, the GDPR is a sweeping new EU law that comes into effect on May 25, 2018. The GDPR harmonizes data privacy laws across the EU and mandates how companies collect, store, delete, modify and otherwise process personal data of EU citizens.

Since our founding, Cloudflare has believed that the protection of our customers’ and their end users’ data is essential to our mission to help build a better internet.

As we explained in a previous blog post last August, Cloudflare has been working hard to achieve GDPR compliance in advance of the effective date, and is committed to help our customers and their partners prepare for GDPR compliance on their side. We understand that compliance with a new set of privacy laws can be challenging, and we are here Continue reading

Weekend Reads: Digital Rights, Extended Random, and the Boundaries of User Privacy

One of the biggest mobile stories of the month has been Apple’s acknowledgement that it deliberately throttles the performance of its recent phones as their battery life decreases. While the company argues this is a helpful feature that extends the useable time of their devices between charges, the announcement has sparked public outcry and multiple lawsuits due to the company’s failure to alert users when throttling was activated or to let them know that if they just replaced their battery their phone would immediately and significantly speed right back up. What does this story reveal about our modern digital rights to the devices we buy? —Kalev Leetaru @ Forbes

That plane flying overhead could very well be scooping up your most intimate data, especially if you live in Texas. The Texas National Guard has reportedly equipped two of its RC-26 military aircraft with cell phone data-collecting dragnets, known as dirt boxes. The ability of government agencies to add new modifications to their aerial surveillance capabilities without any real oversight should sound an alarm for all Americans, not just those who live in the Lone Star State. —Dan King @ The American Conservative

Cisco to MikroTik – command translation – OSPF

In the world of network engineering, learning a new syntax for a NOS can be overwhelming if you need a specific set of config in a short timeframe. The command structure for RouterOS can be a bit challenging if you are used to Cisco CLI commands.

If you’ve been in networking for a while, there’s a good chance you started with Cisco gear and so it is helpful to draw comparisons between the commands, especially if you are trying to build a network with a MikroTik and Cisco router.

This is the second post in a series that creates a Rosetta stone essentially between IOS and RouterOS. We plan to tackle  other command comparisons like MPLS, VLANs and basic operations to make it easier for network engineers trained in Cisco IOS to successfully implement Mikrotik / RouterOS devices.

While many commands have almost the exact same information, others are as close as possible. Since there isn’t always an exact match, sometimes you may have to run two or three commands to get the information needed.
