Framing ATM Cells for Satellite Onboard Switching

1. Introduction There argon many reasons to interconnect transmit and ATM net sounds, in the main the fortuity of truly fast deployment of large-scale broadband service over unsubtle geographical areas. However, several problems arise that prevents a seamless desegregation of these two technologies. For example, the jail cell transport method acting should be adapted to the burst error characteristics of satellite links, which are genuinely different to those of fiber optic; the link memory plan of attack schemes should be optimized for ATM technology; more elaborate transaction management procedures are necessary in send to supply the QoS of ATM connections over satellite channels; etc.[1] Several of these problems cannister be better dealt with if we allow for onboard processing. In fact, the requirement of tawdry and minuscular user terminals has been satisfied by the use of ninefold beams, which suggests the possibility of some form of teddy between beams. O f course, the billet milieu imposes several constraints to the onboard switches, which should be added to the typical system requirements instal in terrestrial networks. These constraints include, mainly, lightweight to meet the size, mass and force out limitations of the satellite, and increase fault tolerance to meet the expected behavior reliableness of the satellite.

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