INTRODUCTION Operation Support Systems/Business Support Systems (OSS/BSS) are the heart of telecom operations and will be heavily impacted with 5G-based application and services. The Next Generation Network (NGN) and its Operations Support Systems (OSS) and Business Support Systems (BSS) market provide capabilities that have become an absolute requirement for Communication Service Providers (CSP) of all types including integrated legacy carriers (fixed, wireless, and cable/Internet), Multiple System Operators (MSO) and Over-the-Top (OTT) providers. Ten years ago, the OSS BSS market was driven largely by a need to consolidate operational support and billing, as well as prepare for next- generation IP-based networks and services. A decade later, these reasons are still important along with many other reasons. 5G will require OSS BSS support for Network Slicing, both in terms of administration of slice allocations (including Service Level Agreements) as well as billing for slices and usage. CSPs will also require OSS BSS for support of massive Internet of Things (MIoT) systems enabled by 5G. The Internet of Things will require operational support for intermediation between networks and systems. IoT

A maintenance release allows the current active software to be incremented in order to address emergency or general maintenance requirements. The update mechanism for the MCS 5100 maintenance releases have the following capabilities: • supports migration of configuration data from one version to the next • provides software rollback capability for use in the event of software or deployment failure • bundles the maintenance release software into an update package to decrease the time required to identify the differences between releases and reduce the time required for the overall update process Maintenance releases are installed and coordinated using both the MCS 5100 and the MAS.interfaces.

    Architecture of NMSs OSI Network Management Telecom Management Network SNMP SMI and MIB Network Management (NETW-1001) Dr. Mohamed Abdelwahab Saleh IET-Networks, GUC Spring 2017 Architecture of NMSs OSI Network Management Telecom Management Network SNMP SMI and MIB TOC 1 Architecture of NMSs 2 OSI Network Management 3 Telecom Management Network 4 SNMP 5 SMI and MIB Architecture of NMSs OSI Network Management Telecom Management Network SNMP SMI and MIB Remote Management A Network Management System (NMS) should implement the \FCAPS" management functions, but how? What are the functional and physical components of a NMS? This is addressed by several standards. We will examine the management framework for the Open Systems Interconnection (OSI) concept and the one for the Telecommunications Management Network (TMN). Both frameworks require that management tasks for network devices can be performed remotely. In other words, management information, such as device configuration, can be transmitted to/from devices in order to collect data or perform operations. Architecture of NMSs OSI Network Management Telecom Management Network SNMP SMI and MIB OSI Network Management Concepts The OSI network management model differentiates between: 1: Management system. It is comprised of managers, which are processes that monitor and perform operations Management system on managed network elements. 2: Managed objects. Managers These are network elements, they represent networking components/resources to be operations notifcations managed, e.g., a switch or an interface on Agent arouter. They are characterized by their: Attributes that distinguish them. Managed Objects Notifications they may send to managers. Operations they accept from managers.

  • FCAPS Tutorial
    Fault And Performance Management In Multi- Cloud Virtual Network Services Using AI: A Tutorial And A Case Study Lav Guptaa*, Tara Salmana, Maede Zolanvaria, Aiman Erbadb, Raj Jaina a Department of Computer Science and Engineering, Washington University in St. Louis, St. Louis, USA b Department of Computer Science and Engineering, Qatar University, Doha, Qatar Abstract— Carriers find Network Function Virtualization (NFV) and multi-cloud computing a potent combination for deploying their network services. The resulting virtual network services (VNS) offer great flexibility and cost advantages to them. However, vesting such services with a level of performance and availability akin to traditional networks has proved to be a difficult problem for academics and practitioners alike. There are a number of reasons for this complexity. The challenging nature of management of fault and performance issues of NFV and multi-cloud based VNSs is an important reason. Rule-based techniques that are used in the traditional physical networks do not work well in the virtual environments. Fortunately, machine and deep learning techniques of Artificial Intelligence (AI) are proving to be effective in this scenario. The main objective of this tutorial is to understand how AI-based techniques can help in fault detection and localization to take such services closer to the performance and availability of the traditional networks. A case study, based on our work in this area, has been included for a better understanding of the concepts. Key Words— Network Function Virtualization, Virtual Network Services, Service Function Chains, Virtual Network Functions, multi- cloud, fault management, performance management, machine learning, deep learning (CSPs).
