Extending HTTP models to Web 2.0 applications: the case of online social networks

摘要: Nowadays, Web 2.0 technologies are a core component of the internet. In fact, they key importance for many modern services, which demand high degree 'social' connectivity. this perspective, online social networks OSNs paradigmatic example new-wave applications, allowing to share user-generated contents, also with interactivity. Moreover, an appealing development platform since can reach vast user base. At same time, their features have been progressively ported cloud environments as produce interactive and collaborative services. However, introduce new usage patterns reflecting specific behaviours within resulting HTTP traffic. As consequence, classical models could fail properly capture essence features. The contribution paper is propose extension standard behavioural models, by explicitly considering elements characterising OSN applications. To aim, it introduces layer modelling defined 'looping'. prove correctness proposed approach, traffic analysis very popular presented.
