The large deployment of Internet resources has facilitated the accelerated development of Intelligent Transport Systems (ITS) including a large diversity of distributed applications such as non-safety infotainment vehicular applications. In vehicular networks, nodes can connect to Internet using Road Side Units (RSUs), but the complete deployment of RSUs along all the transport network seems unfeasible. So, we can take advantage of multihomed devices using complementary access network technologies, such as satellite networks, in order to maintain the connectivity. Several solutions have been implemented in order to take advantage of multihoming and multipath capabilities of mobile nodes. However, in dynamic network scenarios involving multipath communication channels, the QoS requirements of these applications is not always globally managed and guaranteed. Moreover, specific multimedia semantics of the transmitted data is not usually considered by the available transmission mechanisms and protocols. In this work, we present a Multipath TCP communication architecture that take full advantage of the intrinsic multimedia QoS semantics based in Deep Packet Inspection in order to self-manage the available resources and to provide a more compliant e2e transport service.

This paper introduces a Web services based approach that extends resource reservation mechanism for interactive multimedia applications over multimedia satellite systems. It proposes a flexible and extensible scheme for the discovery of services in the network and the configuration of the satellite terminal when resources are requested. It finally presents experimental results of the proposed scheme over a realistic DVB-S2/RCS emulation platform.

This paper introduces a SIP-based approach to offer QoS guaranties to interactive multimedia applications over an efficient DVB-S2/RCS satellite access assignment scheme (on-demand). It focuses both on the communication opening which represents the weakness of on-demand capacity allocation and optimizes the remaining communication in the satellite context (due to important delays). It finally presents analytical and experimental results of the various proposed enhancements.

In the context of multimedia and real-time communication, this paper introduces a standardized way for the packet QoS properties to be represented, in order to allow any of the underlying communication mechanisms to access and use these QoS properties. The QoSxLabel (quality of service cross-layer label) proposes a common syntax expressing the QoS properties. This label is not necessarily added as a new field in the packets but deduced from existing fields according to a well-defined set of rules. The use of the QoSxLabel by some of the mechanisms situated at different levels of the communication architecture allows a fine optimization of the communication services regarding the real application data requirements.

This paper introduces a global XML-based QoS specification language, called XQoS and an associated architecture. The design of this language is driven by the need of a global QoS description language, able to supply a complete description of applications QoS needs that can be easily mapped towards transport, network and system QoS oriented services. Moreover we propose a communication architecture that provides an efficient support to multimedia application of which the QoS needs are explicitly or implicitly expressed from the XQoS approach. This architecture allows a dynamic mapping to be done between the applicative QoS needs and the various available underlying services. An experiment illustrates how XQoS can be used for creating dynamically a protocol architecture that satisfies audio and video on demand applications QoS requirements.
