From the Publisher:
An agent is an entity with domain knowledge, goals and actions. Multi-agent systems are a set of agents which
interact in a common environment. Multi-agent systems deal with the construction of complex systems involving multiple agents and their coordination. A multi-agent system (MAS) is a distributed computing system with
autonomous interacting intelligent agents that coordinate their actions so as to achieve its goal(s) jointly or competitively.

On Multi-Access Edge Computing: A Survey of the Emerging 5G Network Edge Cloud Architecture and Orchestration

The technologies, architectures, and methodologies traditionally used to develop distributed applications exhibit a variety of limitations and drawbacks when applied to large scale distributed settings (e.g., the Internet). In particular, they fail in providing the desired degree of configurability, scalability, and customizability. To address these issues, researchers are investigating a variety of innovative approaches. The most promising and intriguing ones are those based on the ability of moving code across the nodes of a network, exploiting the notion of mobile code. As an emerging research field, code mobility is generating a growing body of scientific literature and industrial developments. Nevertheless, the field is still characterized by the lack of a sound and comprehensive body of concepts and terms. As a consequence, it is rather difficult to understand, assess, and compare the existing approaches. In turn, this limits our ability to fully exploit them in practice, and to further promote the research work on mobile code. Indeed, a significant symptom of this situation is the lack of a commonly accepted and sound definition of the term mobile code itself. This paper presents a conceptual framework for understanding code mobility. The framework is centered around a classification that introduces three dimensions: technologies, design paradigms, and applications. The contribution of the paper is two-fold. First, it provides a set of terms and concepts to understand and compare the approaches based on the notion of mobile code. Second, it introduces criteria and guidelines that support the developer in the identification of the classes of applications that can leverage off of mobile code, in the design of these applications, and, finally, in the selection of the most appropriate implementation technologies. The presentation of the classification is intertwined with a review of state-of-the-art in the field. Finally, the use of the classification is exemplified in a case study.

Understanding code mobility

From state of the art technologies for load balancing and reliability increase in VoIP infrastructures one learns that no homogenous solution exists. Thus compromises have been made as in the number of machines versus achieved reliability, or with regard to separation of load balancing and failure resilience. In this paper we present a distributed architecture for VoIP services based on peer-to-peer principles. In contrast to other peer-to-peer based approaches, relying upon an external DHT service, our architecture utilizes peer-to-peer technologies to integrate load balancing and failover requirements with a centralized VoIP server concept. This results in an integrated solution with focus on today's service provider requirements. Within the scope of this work, a proof-of-concept software solution has been designed and implemented. We show that the proposed architecture can be easily scaled up and provides efficient, redundant storage for user and session data

Reliable VoIP Services Using a Peer-to-Peer Intranet

Cloud computing mechanisms are steadily gaining significance in the field of IT infrastructure hosting and maintenance. To date, we have reached a point where a paradigm shift can be observed. An increasing number of IT players are rethinking the way the technical foundation of their offerings is operated from in-house datacenter hosting towards the outsourcing of infrastructure or services to specialized external cloud computing companies. With the emergence of more and more commercial cloud providers and offerings, combining resources from two or more providers - in order to benefit from factors like price differences, locality of resources, etc. - becomes increasingly feasible for consumers of cloud services. Therefore, it is desirable for such users to have an overarching monitoring system that aggregates a multitude of measurements from resources of different administrative domains in a unified manner. This paper introduces a comprehensive monitoring solution for federated clouds that provides data for both infrastructure providers and cloud users. This system does not only support monitoring resources from heterogeneous domains on both the network and infrastructure level, but moreover provides monitoring support that is able to operate across large numbers of end-to-end resources at the service as well as the application level. In this paper the design of this system as well as its implementation is discussed, and a validation of the system within the context of the European funded project BonFIRE is presented. The utility of the system is shown through the conduct of experimentation.

A monitoring system for federated clouds

Large future internet research programs such as GENI, FIND, and FIRE are under way that will have a global impact on the current and future internet. Experimental facilities and testbeds are needed to support both revolutionary and evolutionary approaches for re-thinking and improving the internet architecture. The resource federation framework proposed by the authors makes available multi-domain testbeds providing heterogeneous crosslayer infrastructures for broad testing and experimentation purposes. Currently, it is unclear how new concepts and ideas developed by the future internet research community can be integrated into production systems while preserving infrastructure operator investments. Service oriented experimental facilities are required that integrate technologies and concepts across various domains and layers and actively incorporate different market players. In this article, we briefly introduce the network domain federation model as the basis and architectural mindset for the Pan-European Laboratory (Panlab) concept, introduce technical architecture refinements, and outline first implementation results.

Pan-European testbed and experimental facility federation – architecture refinement and implementation

The telecommunications environment is changing its face towards an open market of services where the vision is (access to) “information any time, any place, in any form”. Mobility, service personalization and interoperability of services represent fundamental aspects of this environment. In this context a new paradigm is gaining momentum, referred to as “Intelligent Agents”. Unfortunately the term “Intelligent Agent” has become a buzzword and is used in many different contexts. Therefore, this paper provides an overview of the emerging field of Intelligent Agents (IAs) by categorizing the existing types of IAs and identifying their fundamental properties. In addition, the paper identifies potential application areas of IA concepts in the telecommunication environment, focusing on intelligent communications and management, where also the relationships to existing key concepts, such as Intelligent Networks, Telecommunication Management Network and TINA will be addressed.

Quadruple play can be understood as the provisioning of high-speed voice, video (live broadcast or on demand services, such as video on demand), and data services over broadband connections with mobility support. Currently, there are several trials of the IP multimedia subsystem deployed worldwide that promise to provide telecommunication and advanced multimedia services. This article focuses mainly on the basic requirements of a cooperative service delivery platform for provisioning quadruple play services. As a result of this research, an IMS-based cooperative service delivery platform is presented. This supports various access technologies to acquire the streaming services. To validate our quadruple play architecture, we implemented a prototype based on DVB-H and UMTS as the access technologies. This prototype is part of the ongoing development of the proposed architecture
