摘要

综合考虑了突发包所经历跳数和突发包的长度等因素

文章给出了一种新型的支持服务质量（QoS）的光突发交换（OBS）数据信道调度协议——考虑跳数的改进型JET模式下的优先级抢占（H-PPJET）协议。文章在OBS网络环境中对H-PPJET协议进行了仿真

并与JET模式下的优先级抢占（PPJET）协议进行了对比

仿真结果表明

H-PPJET协议改善了网络的吞吐量和丢包率性能。

Abstract

In comprehensive consideration of such factors as the hops and length of bursting packets

a novel QoS-guaranteed Optical Burst Switching（OBS）-based data scheduling protocol named Hops-Preemptive Prioritized Just Enough Time（H-PPJET） protocol is proposed in this paper.H-PPJET is simulated in the OBS network scenario and compared with PPJET protocol.The simulation results show that the H-PPJET protocol outperforms PPJET in terms of network throughput and packet loss rate.
