DYNAMIC BANDWIDTH ALLOCATION AND JITTER HANDLING IN MULTI-TIERED SATELLITE NETWORKS

Abstract: systems and methods for dynamic bandwidth allocation and jitter handling in multi-tiered satellite networks such as virtual communication networks and/or physical communication networks. the system includes bandwidth distributing (bd) unit, in-route group managers (igms), in-route bandwidth manager (ibm). the system functions in multi-tier network entity management mode, and multi-beam management mode. the system operates by periodically collecting bandwidth reports from igms. the bd unit analyzes data in report and compares aggregated bandwidth demand with pre-defined thresholds. if thresholds are exceeded, system switches to multi-tier network entity management mode. in this mode, bd unit determines individual bandwidth adjustments for virtual network and beams and allocates bandwidth for individual devices within virtual network. further, bd unit transmits this information to ibm, which applies allocations, and receives and transmits a scaling factor back to igm indicating utilization of allocated bandwidth. further, bd unit switches back to multi-beam management mode based on comparison result.
