A Vision for Reliable Network Services Architecture

Abstract

Abstract. The increasing complexity, heterogeneity and dynamism of networks, systems and services have made our informational infrastructure unmanageable and insecure. The last events in the European telecom operator and IT landscapes showed inherent limits of current network and systems management architectures with respect to availability, resiliency and QoS. This paper presents a new architectural vision, merging well working technologies to tackle the problem complexity of network services management. Particular attention is drawn on the multiple stakeholders environment, where realistically many parties collaborate to fulfill end-to-end service to end users.

Federated trouble ticket system for service management support in loosely coupled multi‐domain environments

“…Each relationship between SPs is in the form of a customer-supplier relationship supported by the Customer Interface Management and Supplier/Partner Interface Management processes. As this approach is not fully applicable for all federated environments, some extensions to the standard models in the research literature [5,6] propose the interaction between the domains over other functional areas such as service or resource.…”

“…In the research literature [2,[5][6][7][8], authors approached the problem of network management in a federated network architecture through the specification of high-level architectures, frameworks and models that aim to decompose the problem space of federated service operations. Although these papers give a good high-level overview and accurately decompose service management in the federated environment and although various proposed models, technologies, languages and algorithms promise to technologically resolve issues at different layers, these analyses do not reveal the impact of a federation model to the applicability of the overall process.…”

“…We implemented the proposed FTTS using several instances of JIRA 5.1.5 6 and Request Tracker 4.0.5 7 TTSs and FSI/FSD prototypes. The main components are shown in Figure 9, which is a close-up of some of the components shown in Figure 3.…”
