The war against the Ad Blockers

Many web sites these days are identifying which browsers have Ad Blcokers configured, and ask the ad blockers to be disabled. I am not entirely sure whether it is the decision of the ad blocker developers to make these ad blockers easy to detect, or is it technically difficult to implement an ad blocker that can go unnoticed by these web sites.

To be honest, I did not do any research on what is really the case. There is of course some point in these web sites. Their major revenue is from the advertisements, and if we block it through the ad blockers, they lose their major revenue. So I am not going to blame them either. Just wondering who is responsible for the current weak situation with the ad blockers - or is it just Adblock Plus?

Border towns and villages

I am a huge fan of border towns and villages. This was my first border crossing by a train, from Berlin to Küstrin-Kietz (Germany) to Kostrzyn/Küstrin (Poland). I walked for around 12 km in the historical town of Küstrin, and basically roamed around the entire town visiting the landmarks - all without asking anyone routes or using a smart phone for maps. I am happy that I was not lost even at a single point. I guess I am getting used to going to a remote location and starting a random walk.

WiFi Stories

So Ubuntu keeps a list of networks that it had connected to before. You can basically view all those wifi and wired internet connections you had in the past, by
$  ls /etc/NetworkManager/system-connections

I have a long list in my computer. In addition, my phone and Nexus 7 have their own long list. I have even forgotten the origin of some of these system connections - when did I connect to these WiFi networks!

SENDIM for Incremental Development of Cloud Networks: Simulation, Emulation & Deployment Integration Middleware

This is my third and final paper at IC2E 2016. I presented it yesterday. I used a presentation style that is different than my previous presentations, just not to give a repeating feeling to the audience, as majority of them had attended one of my other two presentations. The presentation slides are given below.

Abstract: Cloud networks are tested over simulation, emulation, and physical environments at different stages of development. Configuration management tools manage deployments and migrations across different cloud platforms, mitigating tedious system administration efforts. However, currently a cloud networking simulation cannot be migrated into an emulation, or vice versa, without rewriting and manually re-deploying the simulated application. This paper presents SENDIM, a Simulation, Emulation, aNd Deployment Integration Middleware for cloud networks. As an orchestration platform for incrementally building Software-Defined Cloud Networks (SDCN), SENDIM manages the development and deployment of algorithms and architectures the entire length from visualization, simulation, emulation, to physical deployments.

CHIEF: Controller Farm for Clouds of Software-Defined Community Networks

This is my second presentation at IC2E. Last year also I presented my paper in SDS, and this is my second time publishing my paper at SDS. I always have had a good time at SDS. Given below is the presentation slides.


Abstract: Community networks leverage networking resources from the community itself to offer telecommunication networks for the same community. Software-Defined Networking (SDN) offers a global view of the elements composing the network. Due to its scalability, SDN paradigm has been extended for many other networks including social networks and community networks, in addition to its initial focus, traditional data center networks. This paper designs CHIEF, a networking platform for clouds of Software-Defined Community Networks. CHIEF offers a controller farm through a federation of SDN controllers, to orchestrate the multi-tenanted community network. CHIEF enables interoperable clouds of community networks by extending and deploying a federated and orchestrated cluster of SDN controllers, further enabling complimentary business functionalities such as monitoring, throttling, and metering for inter-community network clouds.
