Service Assurance (SA) is a significant part of Network Function Virtualization (NFV) to enable automated and efficient service delivery from end to end (E2E). In NFV, SA should be integrated into the design and development loop from the beginning. However, it sees slower pace than other NFV management and orchestration (MANO) components. Most of present NFV-SA solutions are partial and do not provide...
Software quality prediction is an important yet difficult problem in software project development and management. Historical datasets can be used to build models for software quality prediction. However, the missing data significantly affects the prediction ability of models in knowledge discovery. Instead of ignoring missing observations, we investigate and improve incomplete-case k-nearest neighbor...
In contrast to the rather network-centric notion of Quality of Service (QoS), the concept of Quality of Experience (QoE) has a strongly user-centric perspective on service quality in communication networks as well as online services. However, related research on QoE so far has largely neglected the question of how to operationalize quality differentiation and to provide corresponding solutions tailored...
Software reuse is a commonly adopted approach to improve productivity and quality of software development. However, the study of embedded software reuse, especially for small and medium sized enterprises (SMEs), is rare. This paper presents an empirical study on the effect of embedded software reuse of a SME. The study focused on the relationship between reuse rate against productivity, cost, quality,...
