Pushing artificial intelligence(AI) from central cloud to network edge has reached board consensus in both industry and academia for materializing the vision of artificial intelligence of things(AIoT) in the sixth-generation(6G) era. This gives rise to an emerging research area known as edge intelligence, which concerns the distillation of human-like intelligence from the vast amount of data scattered at the wireless network edge. Typically, realizing edge intelligence corresponds to the processes of sensing, communication,and computation, which are coupled ingredients for data generation, exchanging, and processing, ***, conventional wireless networks design the three mentioned ingredients separately in a task-agnostic manner, which leads to difficulties in accommodating the stringent demands of ultra-low latency, ultra-high reliability, and high capacity in emerging AI applications like auto-driving and metaverse. This thus prompts a new design paradigm of seamlessly integrated sensing, communication, and computation(ISCC) in a taskoriented manner, which comprehensively accounts for the use of the data in downstream AI tasks. In view of its growing interest, this study provides a timely overview of ISCC for edge intelligence by introducing its basic concept, design challenges, and enabling techniques, surveying the state-of-the-art advancements, and shedding light on the road ahead.

Performance Optimization Across the Edge-Cloud Continuum: A Multi-agent Rollout Approach for Cloud-Native Application Workload Placement

The advancements in virtualization technologies and distributed computing infrastructures have sparked the development of cloud-native applications. This is grounded in the breakdown of a monolithic application into smaller, loosely connected components, often referred to as microservices, enabling enhancements in the application’s performance, flexibility, and resilience, along with better resource utilization. When optimizing the performance of cloud-native applications, specific demands arise in terms of application latency and communication delays between microservices that are not taken into consideration by generic orchestration algorithms. In this work, we propose mechanisms for automating the allocation of computing resources to optimize the service delivery of cloud-native applications over the edge-cloud continuum. We initially introduce the problem’s Mixed Integer Linear Programming (MILP) formulation. Given the potentially overwhelming execution time for real-sized problems, we propose a greedy algorithm, which allocates resources sequentially in a best-fit manner. To further improve the performance, we introduce a multi-agent rollout mechanism that evaluates the immediate effect of decisions but also leverages the underlying greedy heuristic to simulate the decisions anticipated from other agents, encapsulating this in a Reinforcement Learning framework. This approach allows us to effectively manage the performance–execution time trade-off and enhance performance by controlling the exploration of the Rollout mechanism. This flexibility ensures that the system remains adaptive to varied scenarios, making the most of the available computational resources while still ensuring high-quality decisions. © The Author(s) 2024.

Intent-based networking is increasingly used to improve network control and management. Network operators have already begun to adopt this paradigm, which leads to a simplified and automatized network operation. The operators can interact with their intent-driven networks through the Northbound Interface (NBI). Given a standardized NBI, the same approach can scale to coordinate intent provisioning across multi-domain networks in a decentralized fashion. This can outdate traditional decentralized protocols and open new opportunities for flexible and scalable communication mechanisms. This paper proposes a minimal and general high-level architecture, relying on a standard IBN (Intent-Based Networking) architecture, for multi-domain intent deployment in IP-optical networks. Our architecture is consistent between diverse network operators that use the same NBI, respects confidential information, promotes accountability, and can scale for various network services. To achieve this, we introduce a hierarchical system-generated intent schema with automatic intent delegation between the different domains.

IEEE Conference on Standards for communications and Networking (CSCN)

作者： Ijaz Ahmad Jere Malinen Filippos Christou Pawani Porambage Andreas Kirstädter Jani Suomalainen VTT Technical Research Centre of Finland Institute of Communication Networks and Computer Engineering (IKR) University of Stuttgart Germany

Intent-Based Networking (IBN) aims to automate administrative and management tasks in future communications networks. By leveraging networking concepts such as network abstractions and data-plane programmability and using artificial intelligence (AI), IBN improves the overall efficiency of communications networks. IBN employs a closed-loop architecture to monitor and optimize real-time network performance, reduce human intervention, and enhance resilience. However, the paradigm and the technological enablers introduce security challenges. This article studies the security gains and challenges in IBN from the aspect of enabling concepts and technologies. Furthermore, the article highlights potential solutions to existing challenges, outlines the standardization efforts, and summarizes the most important research gaps to advance future research in this direction.

Cloud Data Centers (CDC) are developing rapidly and will have a major impact on IT infrastructures in the future for reasons of their low ramp-up costs and service delivery/support capabilities for the users. In this paper CDCs with multi-service application classes are considered which are operated under an automatic server consolidation based on parallel hysteresis methods for server activations/deactivations which have been reported on our previous work. Each class is subjected to an individual SLA, e.g., for the average service delay for non-real-time services or for delay percentiles for services with strict response time constraints, and probabilities for service rejection (loss) or migration. Operation of a CDC is modeled by Finite State Machine (FSM) - controlled queuing systems for each class of cloud services which are analyzed exactly under Markovian assumptions to receive averages and percentiles of response times and probabilities of loss or migration. The method is novel as it minimizes the energy consumption for servers by an automatic server consolidation strategy while guaranteeing the negotiated SLAs. The method is based on a worst case boundary consideration for the delays of arriving service requests and can be useful to understand the parametric influences and to assess the energy saving gains for multi-tier CDCs. © 2013 IEEE.
