| 摘 要： | 引入广义光突发汇聚(GOBA)概念对传统光突发交换(OBS)进行扩展,形成新的广义OBS(GOBS)网络。针对GOBS的多业务承载目标,提出了一种支持多业务承载的GOBA机制,采用将业务最小时延要求作为汇聚时间的汇聚方式,将多种用户数据业务汇聚到不同粒度的广义数据突发(GDB)中。仿真结果表明,在GOBS环境下,与MSMAP(max burst-size max assembly period)机制相比,GOBA能够在满足较高数据成功接收率的基础上显著地减小约10%的总体数据超时率,同时降低约15%的突发碰撞率,并提高约20%信道利用率。

| Abstract: | A generalized optical burst assembly mechanism(GOBA) to support multi-service is addressed.Using the minimum tolerable time delay of all the service as the assembly time,this mechanism assembles these different services into a generalized data burst(GDB) with different granularities in the OBS edge node.Comparing with the MSMAP mechanism,the GOBA can significantly decrease the overtime rate of total services by about 10%,reduce the burst conflicting ratio by about 15%,and increase the channel utilization ra... |
