Purpose – This paper aims to present the outcome of the i2CAT Foundations’ research and innovation projects that use JXTA P2P technology to share audiovisual content. Design/methodology/approach – The project consisted of designing and developing a distributed application named eRuc that allows management and sharing of audiovisual content. Findings – The paper finds that JXTA is suitable to develop P2P applications that share audiovisual files or that interact with different kind of devices. JXTA services and protocols provide an easy integration with other P2P services and a gain of independence from the topology of the physical network (NAT, firewalls, etc.). Research limitations/implications – High-quality streaming requires specifically designed P2P architectures. Further testing needs to be performed to evaluate whether the use of JXTA, together with proven, efficient P2P streaming architectures, affect the efficiency of the P2P streaming system. Practical/implications – P2P technologies have proven to be very efficient for some kind of applications. However, there are no standard frameworks for interoperability and application development may become difficult. JXTA P2P technologies facilitate application development and integration. The authors have used JXTA in different scenarios related with audiovisual content sharing and have proven its suitability. The current work is focused in P2P streaming. Previous literature suggests that there are some proven architectures for P2P life streaming. Using JXTA together with them may prove if JTXA is suitable for applications that require high bandwidth and minimum delay. Originality/value – The paper provides information of value to information management and technology professionals.
