Unidirectional lightweight encapsulation with header compression for IP based satellite communication over DVB-S

Abstract

The Multi-Protocol Encapsulation (MPE) is a standard method for encapsulating IP packets into MPEG-2 TS frames. However MPE has some disadvantages in simplicity and efficiency to support next generation network. The Unidirectional Lightweight Encapsulation (ULE) is a new solution to overcome limitations of MPE. In ULE, packets are layered directly into the payload field of MPEG-2 TS frames. This is a new encapsulation method for the transport of IPv4 and other network protocol packets directly over MPEG-2 TS. In this paper, we describe the principles and the benefits of ULE and we also proposed Robust Header Compression Scheme to work with ULE in order to enhance the performance of existing ULE. This paper also provides a simulation analysis to show that the new proposed method can offer a better performance in delay, throughput and overhead especially when the packet size is small. © Springer-Verlag Berlin Heidelberg 2007.
