该文提出了一种用于OBS网络的绝对区分服务实现机制PSPJET.该机制结合使用额外偏移时间和Burst抢占/Burst主动分段丢弃技术
既能确保保证业务的数据丢失率不高于要求的最大丢失率
还能有效降低非保证业务的数据丢失率
提高网络性能.和现有的APJET机制相比
PSPJET机制对高业务强度的承受能力更好
还具有无需使用光缓存的优点.
This paper presented an absolute diffserv scheme called PSPJET for OBS networks.The scheme combines the extra offset time and Burst Preemption/Burst active segment dropping.This scheme can ensure that the data loss rate of the guaranteed traffic will not exceed a maximum and the data loss rate of the non-guaranteed traffic is kept to minimum.Compared with the APJET scheme
this scheme can endure higher traffic intensity and needs no optical buffers.
