On the Benefit of Information Centric Networks for Traffic Engineering

Current Internet performs traffic engineering (TE) by estimating traffic matrices on a regular schedule, and allocating flows based upon weights computed from these matrices. This means the allocation is based upon a guess of the traffic in the network based on its history. Information-Centric Networks on the other hand provide a finer-grained description of the traffic: a content between a client and a server is uniquely identified by its name, and the network can therefore learn the size of different content items, and perform traffic engineering and resource allocation accordingly. We claim that Information-Centric Networks can therefore provide a better handle to perform traffic engineering, resulting in significant performance gain. We present a mechanism to perform such resource allocation. We see that our traffic engineering method only requires knowledge of the flow size (which, in ICN, can be learned from previous data transfers) and outperforms a min-MLU allocation in terms of response time. We also see that our method identifies the traffic allocation patterns similar to that of min-MLU without having access to the traffic matrix ahead of time. We show a very significant gain in response time where min MLU is almost 50% slower than our ICN-based TE method

Keeping Continuous Deliveries Safe

Allowing swift release cycles, Continuous Delivery has become popular in application software development and is starting to be applied in safety-critical domains such as the automotive industry. These domains require thorough analysis regarding safety constraints, which can be achieved by formal verification and the execution of safety tests resulting from a safety analysis on the product. With continuous delivery in place, such tests need to be executed with every build to ensure the latest software still fulfills all safety requirements. Even more though, the safety analysis has to be updated with every change to ensure the safety test suite is still up-to-date. We thus propose that a safety analysis should be treated no differently from other deliverables such as source-code and dependencies, formulate guidelines on how to achieve this and advert areas where future research is needed.Comment: 4 pages, 3 figure

Some Thoughts and Reflections on the Fortieth Anniversary of the New York City Human Rights Commission

This article serves as a response to a previous article in this issue, entitled Local Law Enforcement of Laws Prohibiting Discrimination in Housing: The New York City Human Rights Commission, by Michael H. Schill. This article reflects the tripartite structure of Schill\u27s, and comments on each of the three sections in turn: first, the article conducts an analysis of the statistical evidence of housing discrimination; second, this article contemplates the myriad consequences of discrimination on minority communities; finally, the paper concludes with a reflection on the future prospects of the Human Rights Commission in anti-discrimination law

Getting and Keeping Coverage: States' Experience With Citizenship Documentation Rules

South Africa’s Growth Paradox

South Africa has achieved a lot since 1994, when ANC-led government took office. The Performance of the economy since 1994, as measured by the growth rate, has been encouraging with an average growth rate of approximately 2.8% per annum. The inflation rate has been recently under control at between 3% and 6% per annum, the inflation target set by the South African Reserve Bank (SARB). Despite this success problems of unemployment and poverty are still very much with us and have not yet begun to diminish unambiguously. Poverty is around 45% to 50% while broad unemployment rate is somewhere around 26% to 40%. This paper attempts to reexamine the debate on whether SA is experiencing jobless or job creating growth in the context of Okun’s law. Making use of the Structural Vector Autoregressive (SVAR) technique to characterize the dynamics of employment in response to output shocks, this study concludes that while an increase in output increases total employment in general; nevertheless there are some sectors (such as primary and secondary sectors) where the impact of output shocks has been negligible.

Effective Scheduling for Coded Distributed Storage in Wireless Sensor Networks

A distributed storage approach is proposed to access data reliably and to cope with node failures in wireless sensor networks. This approach is based on random linear network coding in combination with a scheduling algorithm based on backpressure. Upper bounds are provided on the maximum rate at which data can be reliably stored. Moreover, it is shown that the backpressure algorithm allows to operate the network in a decentralized fashion for any rate below this maximum
