A peer-to-peer streaming CDN for supporting OTT video broadcast service in mobile networks

Video broadcast is an important feature for over-the-top content providers (OTT-CPs) to disseminate video programs to a large number of Internet mobile users. This paper focuses on a self-sustained content delivery network (CDN) solution, where OTT-CP servers and mobile users collaboratively join together to form a mobile peer-to-peer streaming (MPPS) CDN to assist video broadcasting. Several unique features are introduced to address the vulnerable connectivity issues in a mobile networking environment. The simulation result show that MPPS can agilely adapt to versatile mobile networks to offer stable video broadcast service to a large number of mobile users. The system is under prototyping in a test bed operated by ELTA TV.
