Abstract: Weighted Fair Queuing (WFQ) is introduced into low earth orbit (LEO) satellite networks as scheduling discipline. Based on two bandwidth allocation schemes, two routing algorithms, i.e., Satellite Routing for End-to-end Delay (SRED) and High Performance Satellite Routing (HPSR), are put forward to provide guaranteed end-to-end delay bound for token bucket constrained connections for packet switched LEO satellite networks. The performance of SRED and HPSR is evaluated using a LEO satellite network model in NS2. The simulation results show that both SRED and HPSR are able to provide guaranteed end-to-end delay bound services. The system throughput depends on the traffic characteristics and target delay bound. SRED and HPSR are also able to support multi-class traffic services.
