Analysis of performance issues in point-to-multipoint data transport for big data

This paper describes the state of contemporary open-source reliable multicast solutions and reveals deficiencies regarding their use for massive data transport in Content Delivery Networks (CDN). A performance analysis of the three most popular open-source solutions - UDP-based File Transport Protocol, NACK-oriented Reliable Multicast and Pragmatic General Multicast in multi-gigabit IP-based networks has been performed in the 10Gigabit-WAN laboratory of the Future Internet Lab Anhalt of Anhalt University of Applied Sciences. This evaluation has been performed under the real-world scenario of heavyweight content distribution in Wide Area Networks. Performance evaluation presented in this paper reveals bottlenecks and deficiencies in current approaches. On this basis we propose new ideas for improvements and further development of the reliable multicast data delivery protocols family.
