摘要
首先介绍了支持区分业务的光突发交换(DS-OBS)网络,然后在现有算法LAUC_VF的基础上提出了一种新的调度算法,它的主要思想是:对新来的数据突发首先运用LAUC_VF算法进行数据信道调度;如果调度不成功就采用重调度的机制,该重调度算法命名为:LAUC_VF_RESCHEDULE算法;当重调度不成功时,为了实现业务的区分就采用抢占机制,该抢占算法命名为:LAUC_VF_QIANGZHAN算法;仿真结果表明在大多数情况下该调度算法相对于LAUC_VF算法对网络性能的改善是比较大的。
The optical burst switching networks is introduced for IP differentiated services （DS-OBS）. Then a algorithm based on LAUC_ VF algorithm is discussed. Its key idea is to schedule a new data burst using LAUC_VF algorithm firstly. Ifscheduled not successfully, a rescheduling algorithm named as LAUC_VF RESCHEDULE is used. If this rescbeduling algorithm is failure, a preempted algorithm named as LAUC_VF_QIANGZHAN is used to realize differentiated services at last. The simulation result shows some performances of this algorithm are better than those of the existing LAUC_VF algorithm in most situations.
