Framing ATM Cells for Satellite Onboard Switching

1. Introduction There argon many reasons to interconnect broadcast and ATM net sounds, in the main the fortuity of rattling fast deployment of large-scale broadband service over widely geographical areas. However, several problems arise that prevents a seamless consolidation of these two technologies. For example, the electric cell transport method acting should be adapted to the burst error characteristics of send links, which are rattling different to those of fiber optic; the link memory bother schemes should be optimized for ATM technology; more elaborate dealings management procedures are necessary in cast to encourage the QoS of ATM connections over satellite channels; etc.[1] Several of these problems nominate be better dealt with if we allow for onboard processing. In fact, the requirement of crummy and minuscular user terminals has been satisfied by the use of octuple beams, which suggests the possibility of some form of teddy between beams. Of course, the berth milieu imposes several constraints to the onboard switches, which should be added to the typical system requirements open in terrestrial networks. These constraints include, mainly, lightweight to meet the size, mass and index limitations of the satellite, and increase fault tolerance to meet the expected brio reliableness of the satellite.

[2] For all these reasons, it has been asked if terrestrial ATM cells should be sort out into frames in the first place transmission over satellite channels for onboard displacement [3]. In effect, if to each one user sends its cells directly to the satellite, the contention will work in a cell basis as soundly as the onboard switch ing operations, i.e., one contention and one! switching operation per cell slot. But if we form clusters of users within each spot beam, sort out their cells into frames according to their destination and sending these frames to the satellite, and then the hail of contenders, the number of contentions and the number of switching...
