本文分析了$1+1$路径保护的弹性光网络(EONs)中采用路径交换的碎片整理方案的性能,该方案旨在提高网络中的业务可接纳性。碎片整理方案重新分配备份路径的频谱时隙,并允许重新路由备份路径。碎片整理方案的路径交换功能使主路径成为备份状态,而备份路径成为主路径。仿真结果表明,采用路径交换和重路由的碎片整理方案在业务容许性和时隙利用率方面优于传统的方案。
This paper analyses the performance of the defragmentation scheme using path exchanging in $1+1$ path protected elastic optical networks (EONs), which is intended to improve the traffic admissibility in the network. The defragmentation scheme reallocates spectrum slots of backup paths and allows to reroute the backup paths. The path exchange function of the defragmentation scheme makes the primary paths become the backup state while the backup paths become the primary. The simulation results show that the defragmentation scheme with path exchanging and rerouting outperforms the conventional schemes in terms of traffic admissibility and slot utilization.
