Abstract

The rapid development of onboard processing (OBP) pushes broadband satellite networks to carry on multimedia traffic. However, the function of onboard routing cannot be provided entirely in existing satellite networks with inter-satellite links (ISLs), and QoS of satellite networks cannot be reliably guaranteed because of great difficulties in processing of QoS services. In this paper, a two-layered low earth orbit (LEO) and medium earth orbit (MEO) satellite network (LMSN) is presented. Based on the idea of time-slot division, a novel dynamic hierarchical and distributed QoS routing protocol (HDRP) is investigated, and an adaptive bandwidth-constrained minimum-delay path (BMDP) algorithm is developed to calculate routing tables efficiently using the QoS metric information composed of delays and bandwidth. The performance of the LMSN and HDRP is also evaluated through simulations and theoretical analysis
