e. bitrates) as well as maximum possible and advertised download and upload bitrates of the IAS for fixed broadband networks, or an estimation of maximum and advertised download and upload bitrates of the IAS in mobile broadband networks, and also informa- tion about how the deviations from the advertised download and upload bitrates can impact the services used by end-users. Clear explanation of the remedies available to the customer according to national leg- islation for cases of continuous or regularly recurring discrepancy between the actual and advertised/contracted performance of the IAS in respect to bitrates or other QoS parameters. In Europe, QoS is considered as being part of consumer (i.e. customer) protection. In that regard, consumer protection provisions include QoS supervision and enforcement concerning IAS, which entitles NRAs to monitor the IAS and promote the availability of non-discriminatory IAS with the QoS which reflects current advances in the tech- nologies (e.g. individual bitrates provided in the 2020s are ten times higher than average individual bitrates provided in the 2010s, and SO on). For such purposes, NRAs may impose minimum QoS requirements and other necessary measures on ISPs for IAS pro- vision (as well as for other services). Also, there are obligations imposed on ISPs (and in general, on telecom operators which provide any ICT/telecom services) to make avail- able to the NRA all required information relevant to QoS and network neutrality [7]. The rules for network neutrality in the TSM in Europe have been established to avoid any fragmentation in the single market, and at the same time to create legal certainty for businesses which are using IAS and to make easier their work on an international level. According to the European viewpoint, network neutrality ensures that the Internet will remain a driving engine for innovations, including the recent new technologies (IoT services, 5G services, etc.) and those that will appear in the future. According to the network neutrality
