Design issues for the Generic Stream Encapsulation (GSE) of IP datagrams over DVB-S2

The DVB-S2 standard has brought an unprecedented degree of novelty and flexibility in the way IP datagrams or other network level packets can be transmitted over DVB satellite links, with the introduction of an IP-friendly link layer - he continuous Generic Streams - and the adaptive combination of advanced error coding, modulation and spectrum management techniques. Recently approved by the DVB, the Generic Stream Encapsulation (GSE) used for carrying IP datagrams over DVBS2 implements solutions stemmed from a design rationale quite different from the one behind IP encapsulation schemes over its predecessor DVB-S. This paper highlights GSE's original design choices under the perspective of DVB-S2's innovative features and possibilities

Cell Multiplexing and Adaptive Scheduling for Wide Area ATM Networks

The ATM UBR, GFR over ABR service categories have been designed for data. However several studies have responded poor TCP performance over satellite ATM resources. We first discuss the various design options available for TCP end systems, IP-ATM switches for long latency connections. We discuss the buffer management policies generated and rate services and the virtual stores destination options in ATM. We present comparison of ATM service categories for TCP transport over satellite links. Keywords: Video Teleconferencing, Adaptive Schedulin
