Integrated TMN Service Management

This paper presents a Capability Ontology (CapOnt) and a rule-based reasoning mechanism, which support service management within adaptable service systems. The ontology concepts comprise capability types, capability parameters and service management functions related to capabilities. Capability parameter values can be defined by constraints on other capability parameters. The service management functions included in the ontology are Capability Administration, Capability Configuration, Capability Allocation and Capability Performance Diagnosis. The service management functions are defined by rules consisting of constraints and management actions. The ontology concepts are represented in OWL (Web Ontology Language) and OWL/XDD (XML Declarative Description Language) - a rule-oriented knowledge representation. An intelligent conference room example with simulation results, that demonstrates the CapOnt and the rule-based reasoning, is also presented.

The efficient management of a quality level of Internet service is becoming increasingly important to both customers and service providers. This article describes how service level agreements for multimedia Internet service can be managed and controlled. We first present a literature survey on the problems of SLA management: SLA parameter definition, SLA measurement, and QoS management. We present a utility model to capture the management and control aspects of SLAs for multimedia Internet service. This utility model has been used in microeconomics theory, but here we have applied it to SLA management. This model provides a computationally feasible solution for admission control and quality adaptation for multimedia Internet service and SLA management. It also allows management policies to be flexibly expressed by service providers. Finally, we apply the utility model to the SLA management of VoIP service and describe how to use it for admission control, dynamic quality adaptation, and resource allocation for SLA assurance.

Service Level Agreement (SLA) is an important document to facilitate IT service provisioning by clearly defined Quality of Service (QoS) parameters. The management of SLA is the main subject in the discipline of Service Level Management (SLM) . SLM is very important to improve relationship between IT service provider and its customer. It delivers documented agreement as a common understanding of expectation and possible achievements to the agreed cost. It means SLM builds the interface between an IT organization and its cust omer, so it plays a critical and important role in the context of IT service management. In this paper, an SLM best practice from CISCO will be analyzed with the assessment criteria of SLM framework by Thomas Schaaf. The result will be followed with several suggestion to fulfil the gap in this CISCO’s best practice.

Increasingly, services such as E-commerce, Web hosting, application hosting, etc., are being deployed over an infrastructure that spans multiple control domains. These end-to-end services require cooperation and internetworking between multiple organizations, systems and entities. Currently, there are no standard mechanisms to share selective management information between the various service providers or between service providers and their customers. Such mechanisms are necessary for end-to-end service management and diagnosis as well as for ensuring the service level obligations between a service provider and its customers or partners. In this paper we describe an architecture that uses contracts based on service level agreements (SLA) to share selective management information across administrative boundaries. We also describe the design of a prototype implementation of this architecture that has been used by us for automatically measuring, monitoring, and verifying service level agreements for Internet services.

The existing Service Creation Environments (SCEs) speed up the design of IN service logic, but the whole process of service creation is still relatively long. Very limited support for the service specification and validation provided by the SCEs is one of the reasons. This paper presents a graphical simulation environment called INAP Wrapper that supports IN service prototyping and validation at the early stages of service creation. INAP Wrapper is built around the standard SDL specification of the INAP CS1/2 protocol developed by ETSI. The ETSI specification has been extended by the SDL models of switched network, service management, and service control function. Service validation is based on the SDL simulation capabilities of Telelogic Tau tool suite and the animation capabilities of the INAP Wrapper GUI. The paper presents the INAP Wrapper environment and its industrial applications.KeywordsService LogicBlock TypeService CreationService ValidationService PrototypeThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

The ETSI's Zero touch network and Service Management (ZSM) framework is a prominent initiative to tame the envisioned complexity in operating and managing 5G and beyond networks. To this end, the ZSM framework promotes the shift toward full Automation of Network and Service Management and Operation (ANSMO) by leveraging the flexibility of SDN/NFV technologies along with Artificial Intelligence, combined with the portability and reusability of model-driven, open interfaces. Besides its benefits, each leveraged enabler will bring its own security threats, which should be carefully tackled to make the ANSMO vision a reality. This paper introduces the ZSM's potential attack surface and recommends possible mitigation measures along with some research directions to safeguard ZSM system security.

As SDN technology is becoming popular in the field of computer networks management, the need for evolvable SDN-based network management systems arises. SDN facilitates introducing abstractions to the network through programmability and control separation. In this paper, we propose an abstraction in the SDN management layer through adopting a concept of separation of network concerns. We present a management framework, termed NWManager, that provides an abstraction to the network administrator through policies based on network management functions, like behaviour analysis and monitoring, quality of service preservation and security. And based on network concerns as follows, application, communication, resources concern and common concern representing the area of intersection between basic concerns. NWManager provides various network management functions in one system. Our conducted network simulation scenario by mininet demonstrates that this abstraction and separation of concerns in management layer facilitates and enhances the management of the network. As well, it extends the network control parameters provided to the network administrator.

Rapid growing demand for mobile data traffic challenges capacities and service provision in the next-generation (5G) cellular networks. Real measurement data from operating cellular networks indicates that the traffic models and scenarios disobey our traditional assumptions (i.e., expressing bursty nature). As a result, current network architectures and service management may cause experience deterioration of subscribers in future networks. In this article, we propose three approaches to alleviate the influence of various traffic bursts: baseband resource pool on a cloud platform as wireless infrastructure to enhance the capacity and flexibility of networks, cloud core networks to provide dynamic extension and service flow control abilities, and software-defined bearer networks to simplify service delivery instructed by core networks. Different from conventional stovepipe-like cloud computing network architectures, our proposed architecture interconnects and shares information between entities, breaking through horizontal device barriers and vertical layers. These cloud-based approaches not only avoid the potentially negative impact of bursts, but also provide a software-controlled end-to-end service management framework for future cellular networks. In addition, by taking advantage of open interfaces of cloud-based network elements, service control algorithms and network APIs could also be implemented to realize smart and soft 5G cellular networks.

While worms and their propagation have been a major security threat over the past years, causing major financial losses and down times for many enterprises connected to the Internet, we will argue in this paper that valuable lessons can be learned from them and that network management, which is the activity supposed to prevent them, can actually benefit from their use. We focus on five lessons learned from current malware that can benefit to the network management community. For each topic, we analyse how it is been addressed in standard management frameworks, we identify their limits and describe how current malware already provides efficient solutions to these limits. We illustrate our claim through a case study on a realistic application of worm based network management, which is currently developed in our group.

The proposed architecture is comprehensive and systematic for realization and application of airborne radar network resource management. Moreover, it is totally an integrated closed-loop control system. In addition, a significant interaction between managers and control system is fully considered in this paper.

At present, the development of the hotel entrance guard system tends to be more intelligent. The use of ZigBee wireless sensor networks and ARM embedded technology can solve communication problems for the hotel door terminal node with management server. Based on the Z-Stack, one of ZigBee standard protocol stack, we propose a new hotel access control system. The system selected of TI Company CC2530, adding a high-performance chip card reader MFRC522, has an IC card wireless identification and service management functions. Establish ZigBee wireless sensor networks can reduce the cost of a lot wiring brings and improve the appearance of the hotel. After testing, the program is suitable for access control systems to manage the hotel and the hotel staff can improve work efficiency and service levels.
