Title: M3AT: Monitoring Agents Assignment Model for Data-Intensive Applications

Abstract: Nowadays, massive amounts of data are acquired, transferred, and analyzed nearly in real-time by utilizing a large number of computing and storage elements interconnected through high-speed communication networks. However, one issue that still requires research effort is to enable efficient monitoring of applications and infrastructures of such complex systems. In this paper, we introduce a Integer Linear Programming (ILP) model called M3AT for optimised assignment of monitoring agents and aggregators on large-scale computing systems. We identified a set of requirements from three representative data-intensive applications and exploited them to define the model’s input parameters. We evaluated the scalability of M3AT using the Constraint Integer Programing (SCIP) solver with default configuration based on synthetic data sets. Preliminary results show that the model provides optimal assignments for systems composed of up to 200 monitoring agents while keeping the number of aggregators constant and demonstrates variable sensitivity with respect to the scale of monitoring data aggregators and limitation policies imposed.

Keywords: Monitoring systems, high performance computing, aggregation, systems control, data-intensive systems, generalized assignment problem, SCIP optimization suite.

Narges Mehran presented the paper  “MAPO: A Multi-Objective Model for IoT Application Placement in a Fog Environment” at the 9th International Conference on the Internet of Things, IoT 2019 in Bilbao, Spain (October 22-25, 2019).

Abstract: The emergence of the Fog computing paradigm that leverages in-network virtualized resources raises important challenges in terms of resource and IoT application management in a heterogeneous environment with limited computing resources. In this work, we propose a novel Pareto-based approach for application placement close to the data sources called Multi-objective IoT Application Placement in fOg (MAPO). MAPO models applications based on a finite state machine using three conflicting optimization objectives, completion time, energy consumption, and economic cost, and considering both the computation and communication aspects. In contrast to existing solutions that optimize a single objective, MAPO enables multi-objective energy and cost-aware application placement. To evaluate the quality of the MAPO placements, we created both simulated and real-world testbeds tailored for a set of medical IoT application case studies. Compared to the state-of-the-art approaches, MAPO reduces the economic cost by 28%, while decreasing the energy requirements by 29-64% on average, and improves the completion time by a factor of six.

Philipp Moll presented the paper “Inter-Server Game State Synchronization using Named Data Networking” on the ACM Conference on Information-Centric Networking 2019 in Macau, China.

Abstract: In this paper, we develop a system for inter-server game state synchronization using the NDN architecture. We use Minecraft as a real-world example of online games and extend Minecraft’s single-server architecture to work as multi-server game. In our prototype,we use two different NDN-based approaches for the dissemination of game state updates in server clusters. In a naive approach, servers request game state updates for small segments of the game worldfrom other servers of the cluster. In an improved approach – the region manifest approach– servers identify changed parts of the world by subscribing to manifest files containing information about world regions managed by the other servers of the cluster. An apparent downside of the NDN approaches is the high overhead when handling small-sized game state updates, but our evaluation shows that NDN already improves on IP-based implementations regarding the resulting traffic volume when three or more servers are involved. Furthermore, caused by NDN’s inherent multicast functionality, the advantage over IP increases with the size of theserver cluster. Moreover, the use of NDN-based approaches leads to benefits beyond traffic reduction only. The name-based host-independent access to world regions allows to scale server clusters easier.
