Reflections on security options for the real-time transport protocol framework

The Real-time Transport Protocol (RTP) supports a range of video conferencing, telephony, and streaming video ap- plications, but offers few native security features. We discuss the problem of securing RTP, considering the range of applications. We outline why this makes RTP a difficult protocol to secure, and describe the approach we have recently proposed in the IETF to provide security for RTP applications. This approach treats RTP as a framework with a set of extensible security building blocks, and prescribes mandatory-to-implement security at the level of different application classes, rather than at the level of the media transport protocol

IETF standardization in the field of the Internet of Things (IoT): a survey

Smart embedded objects will become an important part of what is called the Internet of Things. However, the integration of embedded devices into the Internet introduces several challenges, since many of the existing Internet technologies and protocols were not designed for this class of devices. In the past few years, there have been many efforts to enable the extension of Internet technologies to constrained devices. Initially, this resulted in proprietary protocols and architectures. Later, the integration of constrained devices into the Internet was embraced by IETF, moving towards standardized IP-based protocols. In this paper, we will briefly review the history of integrating constrained devices into the Internet, followed by an extensive overview of IETF standardization work in the 6LoWPAN, ROLL and CoRE working groups. This is complemented with a broad overview of related research results that illustrate how this work can be extended or used to tackle other problems and with a discussion on open issues and challenges. As such the aim of this paper is twofold: apart from giving readers solid insights in IETF standardization work on the Internet of Things, it also aims to encourage readers to further explore the world of Internet-connected objects, pointing to future research opportunities

Housing and Mobility Toolkit for San Mateo County

Since the end of the Great Recession, San Mateo County has attracted new workers at a record rate without building anywhere near enough housing. This jobs-housing imbalance drives the cost of housing up and forces many moderate and lower-income employees and their families out of the County. A lack of access to quality affordable housing in the County and the entire Bay Area along with limited transportation options means that an increased number of employees drive in and out of the County every workday. The resultant congestion, gridlock, and long commutes along with other negative environmental, social, and economic impacts create a major concern for communities in the County and beyond. Clearly, this problem has two distinct but interrelated dimensions: housing development and transportation planning. A select group of Mineta Transportation Institute (MTI) Research Associates worked closely with representatives from the San Mateo County Home for All initiative to help address this challenge by developing a toolkit of successful case studies with a holistic approach to housing development and transportation planning

Situating the Next Generation of Impact Measurement and Evaluation for Impact Investing

In taking stock of the landscape, this paper promotes a convergence of methods, building from both the impact investment and evaluation fields.The commitment of impact investors to strengthen the process of generating evidence for their social returns alongside the evidence for financial returns is a veritable game changer. But social change is a complex business and good intentions do not necessarily translate into verifiable impact.As the public sector, bilaterals, and multilaterals increasingly partner with impact investors in achieving collective impact goals, the need for strong evidence about impact becomes even more compelling. The time has come to develop new mindsets and approaches that can be widely shared and employed in ways that will advance the frontier for impact measurement and evaluation of impact investing. Each of the menu options presented in this paper can contribute to building evidence about impact. The next generation of measurement will be stronger if the full range of options comes into play and the more evaluative approaches become commonplace as means for developing evidence and testing assumptions about the processes of change from a stakeholder perspective– with a view toward context and systems.Creating and sharing evidence about impact is a key lever for contributing to greater impact, demonstrating additionality, and for building confidence among potential investors, partners and observers in this emergent industry on its path to maturation. Further, the range of measurement options offers opportunities to choose appropriate approaches that will allow data to contribute to impact management– to improve on the business model of ventures and to improve services and systems that improve conditions for people and households living in poverty.

Integrating Essential Elements of Person-Centered Transition Planning Practices Into the Development of the Individualized Education Program With All Students with Disabilities

This is the second of two white papers that were developed to look at the potential for integrating a person-centered approach into the design and implementation of transition planning with individuals with disabilities in high school across nine demonstration sites in New York State. While the first paper, Infusing a Person-Centered Approach into Transition Planning for Students with Developmental Disabilities, 2001, looked at the barriers present within and between systems of support, this paper provides a deeper view of the strategies, methods and approaches that proved to be effective in supporting and/or sustaining person-centered practices within the Individualized Education Program (IEP) process. Through an emphasis on the need to utilize post-school outcomes as a basis for transition planning, a real example is provided to highlight the contrast between the use of person-centered practices in the development of an IEP and the use of typical special education programming. A model that overlays person-centered practices into the existing IEP process is suggested along with several suggestions proven effective in leading to seamless transition across the school experience. The paper concludes with a review of the data across the project life (1998-2000) identifying the accomplishments and challenges experienced by project participants, as well as overall recommendations to the field

Assessing California's Multiple Pathways Field

The multiple pathways approach to high school education combines rigorous academic learning and career skills to give students the intellectual and real-world experience to succeed in college, career and life. Growing evidence shows that the multiple pathways approach holds promise for increasing academic engagement and achievement, reducing high school dropout rates and boosting students' future earning power. The James Irvine Foundation engaged the Bridgespan Group to assess the state of the multiple pathways field in California and to make recommendations to strengthen it. Assessing California's Multiple Pathways Field: Preparing Youth for Success in College and Career offers findings and recommendations based on a newly developed framework that assesses the multiple pathways field based on five characteristics of strong fields
