This Chapter describes a number of di¿erent techniques, approaches and architectures for cross-layer design. It also seeks to position the work presented throughout this book with respect to current and anticipated standards, indicating opportunities for future standardization. The challenge to be faced is the design of cross-layer mechanisms that can optimize the overall end-to-end application performance over satellite links, while minimizing the utilized radio resources. This optimization can also require additional signaling between the protocol layers. This new area of work is consistent with the end-to-end argument , provided that system-level implications are understood . Suitable methods are expected to improve signi¿cantly the performance of applications in the next generation of satellite systems, but will require changes to the design of protocols and systems, with implications on the related standards. The discussion in this Chapter utilizes some basic ideas introduced in the previous Chapters 1 and 4.
