“…Recently, it has been corroborated the feasibility of using AP to automate SDN management tasks and reduce the time required by network administrators to face network situations [ 3 , 29 ]. However, in such approaches, the network administrator still has to manually describe the network problem in AP notation, which is difficult to interpret without prior knowledge.…”

Realizing autonomic management control loops is pivotal for achieving self-driving networks. Some studies have recently evidence the feasibility of using Automated Planning (AP) to carry out these loops. However, in practice, the use of AP is complicated since network administrators, who are non-experts in Artificial Intelligence, need to define network management policies as AP-goals and combine them with the network status and network management tasks to obtain AP-problems. AP planners use these problems to build up autonomic solutions formed by primitive tasks that modify the initial network state to achieve management goals. Although recent approaches have investigated transforming network management policies expressed in specific languages into low-level configuration rules, transforming these policies expressed in natural language into AP-goals and, subsequently, build up AP-based autonomic management loops remains unexplored. This paper introduces a novel approach, called NORA, to automatically generate AP-problems by translating Goal Policies expressed in natural language into AP-goals and combining them with both the network status and the network management tasks. NORA uses Natural Language Processing as the translation technique and templates as the combination technique to avoid network administrators to learn policy languages or AP-notations. We used a dataset containing Goal Policies to evaluate the NORA’s prototype. The results show that NORA achieves high precision and spends a short-time on generating AP-problems, which evinces NORA aids to overcome barriers to using AP in autonomic network management scenarios.

“…The wide adoption of SDN together with Network Function Virtualization (NFV) has more recently pushed the attention on the softwarization of network services traditionally implemented in hardware [25], [26]. In this scope, Service Function Chaining (SFC) aims at providing an efficient composition and/or orchestration of different and related network applications/functions to achieve a chain of services (building block services) suitable for devices and users in Fog Computing environments.…”

Fog Computing is a recent and compelling paradigm that proposes to run informationprocessing services at the edge of the network. While interesting standardization efforts in Fog Computing are being currently pursued by many organizations, most of them focus on management and orchestration functions, and primarily propose the adoption and adaptation of programming models designed for Cloud applications. Instead, Fog Computing applications would significantly benefit from innovative solutions that, on the one hand, adopt an ''acceptable lossiness'' perspective and manage information processing/dissemination in a dynamic and integrated way and, on the other hand, support a Multi Layer Routing (MLR) approach to exploit multiple routing options at different abstraction levels at the same time. This paper presents an overview of the opportunities and challenges of Fog Computing-based Internet of Things (IoT) applications by jointly exploiting acceptable lossiness and MLR. In addition, the paper proposes the innovative Holistic pRocessing and NETworking (HORNET) Software Defined Networking (SDN) solution which leverages an information-centric and value-based service model and the MLR approach to support IoT applications. The reported preliminary experimental results show the feasibility and effectiveness of the proposed approach. INDEX TERMS Fog computing, IoT, network softwarization, value-of-information (VoI).

“…Bandwidth may also be called network bandwidth, data bandwidth, or digital bandwidth [4,5]. In communication networks, Intermediate nodes (such as a router), and transmission bandwidth play the main role during data packets transmission [6][7][8]. As a result of that, computer communications networks consist of limited resources, which lead to increased competition existing between users on computer networks resources, and thus increasing the competitiveness as well as network resources become more limited [9,10].…”

<p>To implement electronic exams and material resources sharing (which is usually limited), an operating base is must be available for trading information and correspondence management. In this paper, self-managed computer networks, no server was designed. This network aims to share information and correspondence management between the laboratory`s computers. A specific software called Packet tracer used for designing and simulating the network, also for choosing the right medium and install the IP address so that a maximum of data flowing with minimum time and no data loss can be achieved. A class-C IP address was selected since it is the famous class and it doesn`t need any special equipment. Also it has a wide range of of computers in case of expanding the network. We didn`t use a wireless medium to protect the network from hacking. The network was based on an Ethernet medium and a star-connection between the computers with an average signal distributer. An excellent result was achieved after testing the network with a low error percentage, as shown in the result section of this paper.</p>
