With the rapid development of wireless networks, multiple network interfaces are gradually being designed into more and more mobile devices. When it comes to data delivery, Stream Control Transmission Protocol (SCTP)-based Concurrent Multipath Transfer (CMT) has proven to be quite useful solution for multiple home networks, and it could become the key transport protocol for the next generation of wireless communications. The CMT delay caused by data rearrangement has been noticed by researchers, but they have seldom considered the frequent occurrence of packet loss that occurs in the high-loss networks. In this paper, we proposed an original loss-aware solution for multipath concurrent transmission (CMT-LA) that achieves the following goals: (1) identifying packet loss on all paths, (2) distributing packets adaptively across multiple available paths according to their packet loss and loss variation, and (3) maintaining the features of bandwidth aggregation and parallel transmission of CMT while improving the throughput performance. The results of our simulations showed that the proposed CMT-LA reduces reordering delay and unnecessary fast retransmissions, thereby demonstrating that CMT-LA is a more efficient data delivery scheme than classic CMT.

The advent of cloud computing has nurtured an unprecedented growth of datacentres. With its growth, the main concern for service providers and data centre owners is toefficiently manage the energy of the data centres without compromising their computingcapabilities. This concern is genuine as data centres utilise 10-30 times more energy thanoffice spaces and also generate immense heat. As cooling accounts for half of the total powerconsumption in data centres, efficient cooling systems have become a vital need for datacentres. This has resulted in increased research and innovation in the field of efficient coolingof data centres, which in turn has led to growth in filing of patents in this domain. Patents aretechno-legal documents that contain different kinds of information that is accessible to all. Inthe present study, patents are used as source of information for competitive/businessintelligence to highlight the technological trends in the field of energy efficient cooling of datacentres. The study reveals that IBM, HP, Schneider and Hon Hai Industries are the majorplayers working in this technological area. Contrary to the notion that air conditioning wouldbe the most researched area for cooling data centres, the study reveals that there is alsointerest in the hardware of the servers and racks to produce less heat or to have built-incooling mechanisms. The main technologies for which patents are being filed includeventilation using gaseous coolant, technologies related to rack design as well as liquid cooling.Original equipment manufacturers and other vendors have increased filings, along with cloudservice providers. Most of these technologies originate from Asia-Pacific and this region is astrong market, following the USA.

Abstract. The Scientific Committee on Antarctic Research (SCAR) and the Scientific Committee on Oceanic Research (SCOR) jointly intend to build a Southern Ocean Observing System (SOOS). This paper addresses the required data flow infrastructure. SOOS will use a system of systems approach, using existing observation programmes and projects. Data should be submitted to professional data centres. The problem arises how to link all these data centres and get a central overview of the SOOS data as well as direct access to the data. The Netherlands National Oceanographic Data Committee (NL-NODC) has successfully built a national distributed oceanographic data acccess infrastructure, adopting and implementing technology developed by the European SeaDataNet project. The Dutch system has been operational since early 2009. The conclusion is that the SeaDataNet technology can be used to build an operational, distributed data delivery infrastructure, featuring all elements required by the Southern Ocean Observing System (SOOS).
