Abstract
In the Integrated Space and Onboard Network, transmission demands arrive randomly. In addition, the routing algorithm calculate the end-to-end paths the average occupied bandwidth over a period of time, causing microburst of data at the forwarding nodes. The existing queue scheduling methods usually queue the burst data and discard the amount of data which exceed the length of queues, which will cause more severe congestion with the re-transmission of discarded data. In order to solve this problem, a multi-queue scheduling method is proposed to guarantee reliable transmission without loss. Specifically, a token-based mechanism is designed to process the irregular data which has not been sent on time or has been over time in the queue. This mechanism will arrange new transmission opportunities for the data which miss them, avoiding data loss and retransmission. The simulation results show that the proposed reliable transmission mechanism can significantly decrease the network packet loss rate by about 80%, compared to existing queue scheduling methods.
