Hop to Hop的组播拥塞控制

提出了一种基于逐段的网络层组播拥塞控制机制，对其有效性进行了数学推证，证明了信息包在不同优先级的转发约束下，STSR拥塞控制模型的缓冲区共享策略发生拥塞的概率小于分用策略，证明了在组播信息包的优先级高于非组播信息包的前提下，具有组播转发优先的STSR组播拥塞控制模型其缓冲区共享策略，更优于具有同等优先级的组播拥控模型的共享策略，这一结果的取得对于拥塞控制的相关研究具有很大的指导意义。     

Captured Kriegsmarine Enigma Documents at Bletchley Park

Abstract

The discovery of intercepts in the Japanese “Orange Translations” regarding the sinking of merchant ships (marus) bearing allied POWs led to the conclusion that the Joint Intelligence Center Pacific Ocean Area (JICPOA) gave latitudes and longitudes of these vessels to the Commander, Submarine Force, Pacific (ComSubPac) knowing that POWs would be killed. An examination of the “Orange Translations” reveals that most of the intercepts are from the Japanese Water Transport Code (2468) system, not the “Maru Code” (JN-11). The author concludes that while JICPOA provided ComSubPac with convoy coordinates, they were unaware of the presence of POWs on the marus.

Adaptive smooth multicast protocol for multimedia transmission: Implementation details and performance evaluation

In this paper we propose a new single‐rate multicast congestion control scheme named Adaptive Smooth Multicast Protocol (ASMP), for multimedia transmission over best‐effort networks. The smoothness lays in the calculation and adaptation of the transmission rate, which is based on dynamic estimations of protocols' parameters and dynamic adjustment of the ‘smoothness factor’, as well. ASMP key attributes are: (a) TCP‐friendly behavior, (b) adaptive scalability to large sets of receivers, (c) high bandwidth utilization, and finally (d) smooth transmission rates, which are suitable for multimedia applications. We evaluate the performance of ASMP and investigate its behavior under various network conditions through extensive simulations conducted with the network simulator software (ns2). Simulation results show that ASMP can be regarded as a serious competitor of TFMCC and PGMCC. In many cases, ASMP outperforms TFMCC in terms of TCP‐friendliness and smooth transmission rates, while PGMCC presents lower scalability than ASMP. We have implemented ASMP on top of RTP/RTCP protocols in ns2 by adding all the RTP/RTCP protocol's attributes that are defined in RFC 3550 and related to quality of service metrics.

Towards a framework of clean energy technology receptivity

Technology invention, innovation and transfer have been a constant of human evolution. Facing humanity is the threat of anthropogenic climate change, the solution to which is to reduce the rate at which greenhouse gasses (GHGs) are building up in the atmosphere and to deal with the impacts of climate variability and change. To deal with the global crisis requires technology invention, innovation and transfer and changes in behaviour that reduce the GHGs intensity of energy services. Meanwhile, the poverty reduction and development agenda are being shaped by the Millennium Development Goals, which slowly appears to be gaining buy-in. The question is how will the accelerated receipt of cleaner energy technologies can be successfully achieved in marginalised communities in developing countries? The paper considers a range of drivers, case studies and projects that are being undertaken as early Clean Development Mechanism experiments under the banner of the International SouthSouthNorth Group. It discusses the drivers of technology transfer and starts to unpack the elements of successful receptivity through selection and ownership of the newly introduced environmentally safe technologies (ESTs) for the provision of energy services.
