“…Several methods exist since the algorithms can have different degree of sophistication and can use different input information. We can mention the following possibilities: * The requests are based on the length and the input rate to the M\AC queues, as proposed in [2] and [3]. * Instead of using the length and the input rate to the EAC queues, the algorithm uses information from the IP queues.…”

ABSTRACT1The bandwidth-on-demand (BoD) access mechanism plays a key role in DVB-RCS satellite systems in order to optimize bandwidth utilization. Two algorithms intervene in this mechanism, namely the bandwidth allocation algorithm and the bandwidth request algorithm. In this paper a bandwidth request algorithm is proposed. An adaptive version of the algorithm is also presented, which allows for an easy control of the queue size at the terminal even in changing traffic conditions. An event-driven simulator of the BoD loop has been developed and used to evaluate the performance of the proposed algorithm. Simulations have carried out for different combinations of Poisson and VoIP traffic. They show that the algorithm reacts correctly to sudden changes of the input rate and of the received allocation.

“…As DVB-RCS system manufacturers do not make their specific implementation details publicly available, DAMA mechanisms used for this work (operating under the general scheme depicted in Figure 2) have been built on the basis of academic sources [31] and adapted in order to follow SatLabs System Recommendations v2 QoS [30]. The specific implementation has a big impact on the performance, as shown by the experimental results, and it is explained in detail in the following sections.…”

Satellite is often used as an access network in the Next Generation Networks landscape, where multimedia and real-time services are supported by return channels. However, these satellite return channels are a very limited resource with many terminal stations competing for its use, making its efficient assignation one of the key problems to solve in order to increase network performance. This article presents an innovative implementation of the resource allocation mechanism demand assigned multiple access (DAMA) applied to satellite return channel assignment, which provides support for dynamic allocation and quality-of-service. This resource allocation mechanism has been validated with the special purpose advanced Internet network emulator, using the test lab implementation to optimize traffic mapping and queue parameters directly in the field. The numerical results for the different test cases considered are presented, showing that the DAMA algorithm provided is an efficient way of assigning resources, and also helping in the comparison of the different capacity request mechanisms described in the standard.

Emulation is a cost effective and efficient tool to perform performances evaluation and innovative access and network techniques validation. Its ability to interconnect real equipments with real applications provides excellent demonstrations means. The main problem is to overcome the emulation weakness which is the accuracy of the model reproducing the systems to be evaluated. Owing to its modular design and implementation, the PLATINE satellite emulation platform, presented in this paper, is able to emulate a complete DVB-RCS (Digital Video Broadcasting -Return Channel via Satellite)-DVB-S2 (Digital Video Broadcasting -Second) system in a realistic and flexible way. It is possible to configure the platform to emulate a transparent DVB-RCS system dimensioned around a single Hub, or to emulate a system using a regenerative satellite with an onboard switching matrix. Different DVB-RCS protocol stacks are implemented, and the adaptive physical layer is emulated in real time thanks to precalculated DRA schemes and MODCOD files. A DiffServ-like QoS Architecture that couples MAC and IP-Layer QoS mechanisms and Layer 2 security framework are currently under development. At the network side, IPv4 and IPv6 are fully supported as well as IPv6 mobility and dynamic multicast. In this paper, we mainly focus on the emulation platform and the tools developed to help the performance analysis of the emulated system.
