Abstract
Abstract
The edge nodes of the satellite optical burst switching network are the interface devices of the ground network and the satellite optical burst network. Ground network data needs to be classified, assembled, and generated bursts at the edge nodes. The burst will be transmitted on different wavelength channels. Reasonable selection of the assembly algorithm of the edge nodes can reduce the design complexity and improve the forwarding performance and QoS capability of the satellite optical burst switching network. In this paper, an adaptive assembly algorithm is proposed to adjust the length threshold and time threshold dynamically. The basic principle is to evaluate current network traffic depend on the actual burst parameters of previous bursts, and then determine the specific value of length threshold and time threshold. The algorithm is implemented on a Xilinx’s XC7VX690T-2FFG1927I FPGA, and verified by Modelsim SE 10.6d.
