摘　　要：由于流量工程协议和流量管理机制的系统配置会间接地对光传送网络设置的整体能量效率造成显著影响,为此研究评估了通用多协议标记交换(GMPLS)协议和光突发交换(OBS)技术中的管理配置问题。仿真结果表明:对于GMPLS链路捆绑机制,双向标记交换路径(LSP)的中间节点数量从4个增加到40个时,后者的功耗是前者的2.5倍;对于OBS技术,当增加每个突发中的分组数量时,OBS交换的功耗会下降。当每个突发的分组数量较小时,JET协议的能量效率更高;当每个突发包的数量更大时,TAW协议的能量效率更高。As the system configuration of traffic engineering protocol and traffic management mechanism, can signifi- cantly affect the overall energy efficiency of the optical transport network. Therefore, the management configuration problem of the general multiple protocol label switching （GMPLS） protocol and the optical burst switching （OBS） technology is studied and evaluated. Simulation results show that, for the GMPLS link bundling mechanism, when the num- ber of intermediate nodes in LSP increases from 4 to 40, the power consumption of the latter is 2.5 times as much as that of the former. For OBS technology, the power consumption of OBS switching will decrease when the number of packets in each burst is increased. When the number of burst packets is small, the energy efficiency of JET protocol is higher. And when the number of burst packets is larger, the energy efficiency of TAW protocol is higher.
