Edge computing is an emerging architecture in 5G networks where computing power is provided at the edge of the fixed network, to be as close as possible to the end users. Computation offloading, better communication latency, and reduction of traffic in the core network are just some of the possible benefits. However, the Quality of Experience (QoE) depends significantly on the network performance of the user device towards the edge server vs. cloud server, which is not known a priori and may generally change very fast, especially in heterogeneous, dense, and mobile deployments. Building on the emergence of standard interfaces for the installation and operation of thirdparty edge applications in a mobile network, such as the Multi-Access Edge Computing (MEC) under standardization at the European Telecommunications Standards Institute (ETSI), we propose MECPerf, a tool for user-driven network performance measurements. Bandwidth and latency on different network segments are measured and stored in a central repository, from where they can be analyzed, e.g., by application and service providers without access to the underlying network management services, for run-time resource optimization.Index Terms-Edge computing, Network measurements, 5G.1 Admittedly, the standard does allow an application to specify Service Level Agreement (SLA) guarantees upon context creation, but the way how there are handled and what happens in case they are (temporarily) violated is left to the equipment manufacturers.

<p>Recent climate, health and economic emergencies have put a strain on sustainable transition national and supranational systems and it has been showed how much human beings depend on the environment. In this context, it is relevant to address which role public law should embody in climate change adaptation. It is of course a complex question and it has at least two sides: public law could be an essential vehicle for implementing adaptation policy across a range of sector and a source for providing policies aimed at changing behaviour.</p> <p>For instance, in the field of climate change, the regulatory problem arises in terms of good administration/governance. Public law could also, however, be interpreted as a tool for communicative action that may enhance co-operation in the municipal organization. In fact, the local government and private actors play an important role in the implementation of climate change adaptation. It follows that law-making is one of the key institutions providing the means to set priorities for climate action.</p> <p>Being more specific, policy intervention sets objectives; the law (or regulation) tells how to reach them, determining the procedures that must be respected. Thus, policies are more widespread internationally, while laws at the domestic level.</p> <p>Using the words of the HRH Sultan Azlam Shah, former Chief Justice of Malaysia, «legal principles and rules help convert our knowledge of what needs to be done into binding rules that govern human behaviour. Law is the bridge between scientific knowledge and political action» (23 August 1997). In order to catch the characteristics of the two tools in question it will be measured the effectiveness of non-binding solutions, such as the Glasgow Climate Pact (COP26), and legislative tools as the European regulation n. 2021/1119 on green deal. The expected results of the study are a lack of effectiveness of planning tools at an international level, while local legislation keeps exceptional leeway for local administrators, free not to proactively involve stakeholders.</p> <p>It will also address the relationship between national and supranational level’s planning: for these purposes, it will be relevant to analyse, in a comparative perspective, the impact of the Italian Piano per la Transizione energetica and Spanish legislation 2021/7, on <em>Cambio Climático y Transición Energética.</em></p>
