This second special issue, "Assessments, Models and Evaluation", in- cludes a collection of Kaleidoscope papers that address the performance of ICT networks and emerging capabilities to streamline performance, quality of service (QoS) and quality of experience (QoE). ITU's standardization work targets operational aspects of performance, QoS and QoE; the end-to-end quality aspects of interoperability; and the development of both subjective and objective quality-assessment methodologies for multimedia services. ITU-T Study Group 12 - ITU's standardization expert group responsible for perfor- mance, QoS and QoE - is considering the integration of some of these papers' findings into its standardization work.' The five papers and their respective authors are as follows: 1. CollaborationbetweenNetworkPlayersofInformationCentricNetwork: An Engineering-Economic Analysis.
