Link State Contract Routing

The Internet's simple design resulted in huge success in basic telecommunicationservices. However, the current Internet architecture has failed in terms of introducingmany innovative technologies as end-to-end (E2E) services such as multicasting,guaranteed quality of services (QoS) and many others. We argue that contractingover static service level agreements (SLA) and point-to-anywhere service definitionsare the main reasons behind this failure. In that sense, the Internet architecture needsmajor shifts since it neither allows (i) users to indicate their value choices at sufficientgranularity nor (ii) providers to manage risks involved in investment for new innovativeQoS technologies and business relationships with other providers as well as users.To allow these much needed economic flexibilities, we introduce contract-switching asa new paradigm for the design of future Internet architecture. In this work, we implementcontract-routing framework with specific focus on long-term contracted servicesin Link State Contract Routing scheme. Our work shows that E2e guaranteed QoSservices can be achieved in routing over contracted edge-to-edge service abstractionswhich are built on today's popular protocols with reasonable protocol overhead

CloudJet4BigData: Streamlining Big Data via an Accelerated Socket Interface

Big data needs to feed users with fresh processing results and cloud platforms can be used to speed up big data applications. This paper describes a new data communication protocol (CloudJet) for long distance and large volume big data accessing operations to alleviate the large latencies encountered in sharing big data resources in the clouds. It encapsulates a dynamic multi-stream/multi-path engine at the socket level, which conforms to Portable Operating System Interface (POSIX) and thereby can accelerate any POSIX-compatible applications across IP based networks. It was demonstrated that CloudJet accelerates typical big data applications such as very large database (VLDB), data mining, media streaming and office applications by up to tenfold in real-world tests

Drivers and Impacts of R&D Adoption on Transport and Logistics Services

Actually, technologies and applications in industries are changing via business restructuring, new business models, new knowledge and supply chains. So R&D is not focused primarily on manufacturing industry as it used to be, but on different kinds of industries as logistics and transport (TLS). Nevertheless, the characteristics of the TLS industry determine the introduction of specific R&D solutions accordingly to sectors operations. The objective of this paper is to describe the R&D opportunities in the TLS industry and how managers use them to make their businesses more innovative and efficient. Using the Structure-Conduct-Performance (SCP) model the paper identifies the links between R&D adoption and innovation dynamics. Relating the findings, on the driver’s side there are three points that are worth mentioning: increasing market competition, the relationships of firms interacting with each other and the availability and quality of complementary assets such as employee skills and IT know-how. On the impacts’ side, firms advanced in terms of implementing R&D solutions are more likely to implement organizational changes. Finally, a set of recommendations on how to further improve the continuous innovation in the TLS industry is presented
