Researchers jump aboard Pica8's OpenFlow switches as centralized management beckons

Reblogged from GigaOM:

Longtime vendors might not want to admit it, but the OpenFlow protocol is turning out to be an important development in the world of networking. The latest evidence comes from Illinois, where 13 OpenFlow switches from scrappy networking startup Pica8 are empowering academics to more easily monitor their networks for security problems in real time and other functions.

Researchers at the University of Illinois at Urbana-Champaign ended up deploying Pica8's P-3290 switches because they support OpenFlow and because they boast 1-gigabit Ethernet.

In fact OpenFlow (part of Software Defined Networks =SDN) does virtualize complex routers into simple decentral COTS routers and central flow control management in big data centres. Google started this new trend by implementing OpenFlow in their worldwide network. Jaap van till, connectivist

Mobiele operators gaan in de nabije toekomst waarschijnlijk steeds meer mobiel dataverkeer offloaden naar WiFi-hotspots en small cells. Dit constateren onderzoekers van Juniper Research.

Confirms the view I expressed before about Small Cells in homes and offices which will combine to cover busy area's in cities. Macrocell G4 base stations can simply not be rolled out in huge numbers fast enough. Higher speeds mean smaller area's---> more base stations and fiber backhauls. So Wi-Fi must be used too. I am curious how the new Wi-Fi 802.11ah of the new Apple Airports and phones/pads/laptops will impact this wireless access. Jaap van till, connectivist

What can we learn from the beating heart of Gezi Park, the blood soaked Taksim concrete, the barricades of Besiktas? One thing: the dream of a Global Spring is not dead. It is still in its infancy, kicking and screaming.

Look around! This is what democracy looks like. The future is being built as we speak. What will it be? Singularity, or Nightfall?

The Regulation of Ant Colony Foraging Activity without Spatial Information

See on Scoop.it - Bounded Rationality and Beyond

Many dynamical networks, such as the ones that produce the collective behavior of social insects, operate without any central control, instead arising from local interactions among individuals. A well-studied example is the formation of recruitment trails in ant colonies, but many ant species do not use pheromone trails. We present a model of the regulation of foraging by harvester ant (Pogonomyrmex barbatus) colonies.

The Young Turks

NYT Turks

1. What do the young Turks want? Here is the text of the crowdfunded full-page ad in the NYT:

======What is Happening in Turkey?===========

People of Turkey have spoken: We will not be oppressed!

Millions are outraged by the violent reaction of their government to a peaceful protest aimed at saving Istanbul’s Gezi Park.

Outraged, yet not surprised.

Over the course of Prime Minister Erdoğan’s ten-year term, we have witnessed a steady erosion of our civil rights and freedoms. Arrests of numerous journalists, artists, and elected officials and restrictions on freedom of speech, minorities’ and women’s rights all demonstrate that the ruling party is not serious about democracy.

Time and again, the Prime Minister has mocked and trivialized his nation’s concerns while Turkey’s own media have remained shamefully silent.

The people protesting bravely throughout Turkey are ordinary citizens. We span several generations and represent a spectrum of ethnic, religious, socioeconomic, ideological, sexual, and gender identities. We stand united because of our concern for Turkey’s future. Our future.

We demand an end to police brutality.
We demand a free media.
We demand open democratic dialogue between citizens and those elected to public service, not the dictates of special interests.
We demand an investigation of the government’s recent abuse of power, which has led to the loss of innocent lives.

Join the conversation and stand with us in solidarity.

Crowdfunded Entirely by Concerned Individuals from Around the World===================================

# Link: http://www.indiegogo.com/projects/full-page-ad-for-turkish-democracy-in-action  (with hat tip to Sara Wedeman for finding it).

# Essential to real democracy is that it is more than ‘having elections’, but that the majority which takes a decision on an issue takes expressed minority views on it into consideration too. Reason behind taking them seriously is that the next government may include some of these opponents and activists, who may have valuable contributions to solving problemsand issues.

2. Who are these people who gathered on squares in Turkey?

“Who Are the Demonstrators in Turkey? Researchers Making Some Interesting Discoveries” – WSJ http://t.co/W4YwalynKO /cc

My impression is that the young people gathering on the squares in Turkey are “the Creative Class” who can not function without room for expression in freedom and open discussion, to be able to create value, jobs and wealth. In other words, they are Turkey’s HOPE in uncertain times.

3. Documentary film about the #GeziPark demonstrations.
