Towards an incremental deployment of ERN protocols: a proposal for an E2E-ERN hybrid protocol
Get PDFWe propose an architecture based on a hybrid E2E-ERN approach to allow incremental deployment of ERN (Explicit Rate Notification) protocols in heterogeneous networks. The proposed IP-ERN architecture combines E2E (End-to-End)and ERN protocols and uses the minimum between both congestion windows to perform. Without introducing complex operation, the resulting E2E-ERN protocol provides inter and intra protocol fairness and benefits from all ERN protocol advantages when possible. We detail the principle of this novel IP-ERN architecture and show that this architecture is highly adaptive to the network dynamic and is compliant with IPv4, IPv6 as well as IP-in-IP tunneling solutions
An IP-ERN architecture to enable hybrid E2E/ERN protocol and application to satellite networking
Get PDFWe propose an architecture based on a hybrid E2E-ERN approach allowing ERN protocols to be inter-operable with current IP-based networks. Without introducing complex operations, the resulting E2E-ERN protocol provides inter and intra protocol fairness and benefits from all ERN advantages when possible. We detail the principle of this novel architecture, called IP-ERN, and show that this architecture is highly adaptive to the network dynamics and is compliant with every TCP feature, IPv4, IPv6 as well as IP-in-IP tunneling solutions. As a possible use case, we test this architecture as a potential candidate to replace Performance Enhancing Proxies (PEPs) commonly-used over satellite IP-based networks. Compared to splitting PEP, the IP-ERN architecture does not break the E2E connectivity, still achieves high satellite link utilization and fairness without needs of extra fault tolerant mechanism

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

RESILINK: increasing resilience of smallholders with multi-platforms linking localized resource sharing
Get PDFAgriculture is an important sector for income generation, employment and food security in North Africa. Increasing the resilience of smallholders to face unexpected crises is a multidimensional challenge that requires a multifaceted policy. However, common to most crisis situations, the restrictions on movements has many impacts on the availability of distant resources such as agricultural supplies, equipment, services, labours and access to markets to name a few.RESILINK [1] is a Research & Innovation Action (RIA) project funded by the PRIMA organization in the context of the 2021 Section 2 call on Increasing the resilience of small-scale farms to global challenges and COVID-like crisis by using adapted technologies, smart agri-food supply chain and crisis management tools.RESILINK will increase smallholder’s resilience by providing continuity of access to both resources and markets in crisis situations. It will empower the local agri-food value chain model by optimizing usage of local resources, promoting and generalizing local resource sharing approach and facilitating territorial markets. This local agri-food value chain model will also be integrated with the local e-commerce, supply & distribution channels. The concept of localized and short agri-food value chain will also impact on the agro ecological system by minimizing the food losses and contributing to the climate & environment changes with shorter food supply chains and logistics. As a result, new and local innovative services can be identified and created, enhancing further the smallholders' agri-food chain.To implement the generalizing local resource sharing approach, RESILINK will develop a distributed digital resource management platform for real-time exchange of information on territorial resources and supplies & demands; connecting smallholders to new supply, sharing opportunities and distribution channels.While the ideas of connecting smallholders to market and sharing resources are not new, the approach taken by RESILINK is to provide a unique platform-of-platforms capable of integrating existing or future platforms into comprehensive dashboards/portfolios. To achieve its objectives, RESILINK will:develop a resilient RESILINK network ensuring high availability of services where number of distributed, light-weight and collaborating platforms that will be run on the network of Edge-IoT gateways;implement the platform-of-platforms approach for large-scale adoption and sustainability: (a) RESILINK wrapper components will enable resources from existing digital platforms to be discovered & integrated and, (b) RESILINK open API will allow development of new digital sharing platforms that can fully inter-operate with the RESILINK digital resource management platform to benefit from the RESILINK community;use cutting-edge modern Artificial Intelligence where RESILINK’s digital platform will leverage contextual intelligence to efficiently discover resources, identify trends, forecast and propose pertinent correlated resources;seamlessly integrate IoT technologies to automatize a number of information exchanges related to resource sharing. RESILINK will further develop Edge-IoT components and demonstrate IoT integration benefits for resource sharing;run an extensive piloting & evaluation program with smallholders for large-scale testing to ensure RESILINK’s concepts acceptance and validate RESILINK components in a step-by-step and incremental manner;</ul
