Current IP-based solutions for conversational services use push-based data transfer only, since pull-based communication as envisaged in Named Data Networking (NDN) suffers from the two-way delay. Unfortunately, IP's addressing scheme requires additional services for contacting communication partners. NDN provides an inherent solution for this issue by using a location-independent naming scheme. Nevertheless, it currently does not provide a mechanism for push-based data transfer. In this paper, we investigate Persistent Interests as a solution for push-based communication. We improve and implement the idea of Persistent Interests, and study their applicability for conversational services in NDN. This is done by comparing different push- and pull-based approaches for Internet telephony.}, doi = {10.1109/ICMEW.2017.8026212}, isbn13 = {978-1-5386-0560-8}, language = {EN}, location = {Hong Kong}, pdf = {https://www.itec.aau.at/bib/files/MuSIC_2017.pdf}, talkdate = {2017.07.10}, talktype = {registered}, url = {http://ieeexplore.ieee.org/document/8026212/} }
