Evaluating Web Traffic Performance over DVB-RCS2

The web has undergone a radical change over time. Changes not only in the volume of data transferred, but also the way content is delivered to the user. Current web server architectures are often highly distributed and adapted for user interaction, with transactions characterised by multiple connections to multiple servers. This paper discusses the implication of this new web on next generation two-way satellite systems. It seeks to answer the question of whether classical resource provisioning remains suitable for this traffic. It first presents a more representative simulation model that captures the key features of modern web traffic. It then uses simulation to evaluate the performance over the second generation of DVB-RCS, assessing the impact on performance for a range of bandwidth on demand methods. This paper may be used to formulate recommendations for how to support web traffic in DVB-RCS2.
