For this reason they are particularly useful in environment where no fixed network infrastructure is available. For example, they are well suitable for emergency application, when fixed telecommunication infrastructures, whereas present, can be seriously damaged or destroyed. Satellite networks also work without terrestrial infrastructure, excluding one gateway localized inside the footprint, and are easy to be set up too. For the same reasons also satellites can be fruitfully be utilized in case of emergency. Nevertheless, these two technologies are not in competition, as they might appear, but absolutely complementary. In fact, ad hoc mobile networks are characterized by very small terminals, low consumption, limited capacity per user terminals...

Most of the SPDY techniques (i.e. header compression, pushing and multiplexing) are usually included in satellite Performance Enhancing Proxies (PEPs) to optimize performance. Therefore, SPDY over satellite is expected to improve performance but without the need of any specific modification over the network. Proof of such an improvement is revolutionary for the role of satellite in the future Internet, since it could be considered as a transparent link, which does not need ad-hoc protocol adaptations. This paper addresses Web performance over satellite using the new SPDY protocol. Performance assessment relies on a satellite emulator that reproduces in software a DVB-RCS link while running real implementations of both TCP/IP stacks and SPDY.

To this aim, SPDY is a protocol engineered to reduce download times of content rich pages, as well as for managing links characterized by large Round Trip Times (RTTs) and high packet losses. With such features, it could be an efficient solution to cope with performance degradations of HTTP over satellite. In this perspective, this paper compares the behaviors of HTTP and SPDY over a DVB-RCS satellite link. To conduct a thorough set of tests over a realistic scenario, we used the Satellite Network Emulation Platform (SNEP). In addition, we evaluated how different Bandwidth on Demand (BoD) methods impact over the retrieval of a page. Results clearly indicate that SPDY could be an effective solution to deliver Web contents over satellites in a more �efficient manner.
