P88/1 Dynamic bandwidth allocation for LAN2LAN interconnection

This paper proposes architecture to interconnect remotely located heterogeneous terrestrial distribution nodes in a mesh topology. The meshed topology was achieved through the use of an on board regenerative satellite. An emulated DVB-S regenerative environment was created using an actual transparent GEO satellite. Furthermore a dynamic bandwidth mechanism is proposed, applied directly on the DVB-S stream of the uplink of each distribution node was performed to achieve efficient usage of the available bandwidth. This dynamic bandwidth mechanism enables the provision of interactive IP based multimedia services, at a guaranteed QoS. An actual GEO satellite link has been used to demonstrate the interoperability of DVB-S, DVB-T and WLAN networks, to validate the performance of the network architecture and the bandwidth management mechanism
