NSA using OpenFlow for SDN

NSA using OpenFlow for SDN

Even the National Security Agency is using software defined networking these days.

Bryan Larish, the NSA's technical director for enterprise connectivity and specialized IT services, spoke at the recent Open Network Summit in Silicon Valley, and said the intelligence agency is deploy an OpenFlow SDN for its internal operations. 

OpenFlow is one of the leading SDN protocols that allows centralized control and easy reprogramming of the packet-moving decisions on a network.

“We as an enterprise need to be able to control our network,” Larish told CIO.com. “OpenFlow centralized control seemed the only viable way to do this from a technical perspective. We are all in on OpenFlow.”

NSA is testing an OpenFlow SDN at both its main campus and branch offices, CIO.com reports. At NSA headquarters, the deployment is limited to a small section of the network for development.   The agency is also using OpenStack in its data centers, Larish said, and NSA is looking to other commercially available products to address its network integration and management needs.

EPA compliance database expanded to address dirty air

EPA compliance database expanded to address dirty air

The Environmental Protection Agency has added air pollution information to its database of compliance history. With this upgrade, users can now view and compare air quality data and facility compliance information on one web page, as opposed to searching through four different websites and databases.

The addition of air pollution data to the Enforcement and Compliance History Online (ECHO) database gives users a way to combine data and facility compliance information from the Toxic Release Inventory, National Emissions Inventory, Greenhouse Gas Reporting Program and Acid Rain Program.

Users can search by location, facility type, environmental conditions, year, emission amount, pollutant type, and enforcement/compliance actions and violations. Subcategories exist as well, helping users find exactly what they need.

This new feature adds to a string of recent improvements to ECHO:

  • Dashboards featuring interactive graphs, charts and easy-to-analyze data have been added to illustrate facility compliance with pesticide information, as well as public water system violations and compliance data surrounding the Safe Drinking Water Act.
  • ECHO widgets and web services allow developers to leverage data and reports into their own websites.
  • A new customizable mapping tool showing the compliance status of EPA-regulated facilities lets users create customized maps using current data.

Charlotte updates Citygram with more open data

Charlotte updates Citygram with more open data

Citizens of Charlotte, N.C., can now get notices when rezoning plans are submitted for review, thanks to an upgrade to Citygram, a web app that notifies subscribers of non-emergency events. The added functionality is part of Charlotte’s ongoing efforts to increase government transparency and better connect citizens to city hall. According to the city, more than 200 subscribers have already received 65,000 notifications.

Originally developed in 2014 by a Code for America team working in Charlotte, Citygram leverages operational data from the city's Open Data Portal, a one-stop shop for information on transportation, community safety, neighborhoods and housing. Residents subscribe to topics on Citygram, and information is sent directly to them via text or email.

The service has expanded beyond Charlotte, and covers Seattle, New York, San Francisco and Lexington, Ky., as well.

As a city grows its library of datasets, Citygram can be updated to include them. According to Charlotte officials, possible additions may include 311 calls for service and street closures.

The Citygram project is now managed by the Code for Charlotte, a brigade of Code for America. The brigade was established following last year’s Code for America’s 2014 Fellowship program, in which technologists from the organization worked with the city to strengthen open government-citizen relationships.

White House updating opengov roadmap

White House updating opengov roadmap

Open government advocates should put on their thinking caps as the United States plans its third National Action Plan (NAP), writes Corinna Zarek of the Office of Science and Technology Policy.

The first U.S. NAP was published in 2011. The second, published in 2013, is still being implemented through the end of 2015. The third NAP will expand on existing initiatives and address new ways to improve government transparency, accountability and response in the next two years.

Zarek calls on the public to suggest “expanded commitments” related to topic addressed by first two plans, such as public participation, open data, records management or natural resource revenue transparency. New ideas are also encouraged.

Suggestions for the plan can be sent to opengov@ostp.gov. Participants can also contribute ideas to a publicly available Hackpad that GSA is helping coordinate, Zarek said.

Saildrones take to Alaska seas

Following the successful exploration of the Bering Sea by unmanned surface vehicle recently, the National Oceanic and Atmospheric Administration plans to redeploy the saildrones, outfitting them with a suite of meteorological and oceanographic sensors to explore fish populations. According to a recent award notice, the saildrones will be equipped with echosounders for use in applied fisheries management in the Bering Sea and the Gulf of Alaska.

NOAA wishes to collect data on conductivity, sea temperature, wind, air temperature, humidity, barometric pressure, dissolved oxygen and chlorophyll fluorescence, according to the performance work statement .  The data will be tagged with a GPS time and position, and fed back to NOAA via Iridium satellite communication links.  The system architecture will segregate vehicle housekeeping data from scientific data and format the data for exfiltration and post-processing,  NOAA said. 

The saildrones will be deployed for about 3 months.
