Abstract
In this paper, we combine optical burst switching (OBS) for managing congestions and multiprotocol label switching (MPLS) for handling routing and quality of service (QoS). The performance of two control plane mechanisms such as MPLS explicit routing and interior gateway protocol (IGP) shortest path are examined and numerical results are presented on the throughput and the round trip time (RTT). Using MPLS explicit routing the throughput is 42 percent higher than that for the IGP protocol and the RTT demonstrates an improvement of 57 percent compared IGP shortest path. In addition, the average RTT time for IGP is six times higher with the explicit routing MPLS. Therefore, it is proven that improved QoS for IP over OBS-WDM networks is achieved using MPLS explicit routing.
本文将光突发交换(OBS)与多协议标签交换(MPLS)相结合，用于管理拥塞和处理路由和服务质量(QoS)。研究了MPLS显式路由和IGP最短路径两种控制平面机制的性能，并给出了吞吐量和往返时间的数值计算结果。使用MPLS显式路由的吞吐量比使用IGP协议的吞吐量高42%，RTT比使用IGP最短路径的吞吐量提高57%。此外，IGP的平均RTT时间是显式路由MPLS的6倍。因此，证明了使用MPLS显式路由可以提高IP over OBS-WDM网络的QoS。
