摘要

随着大数据、云服务和人工智能的发展，网络向着规模化与复杂化方向演进，网络发生故障的概率增加，需要为每个连接请求提供专用保护，减少因网络故障造成的损失。因此，在数据中心弹性光网络中，为了提高网络的生存性，采用带宽调整方法。文章提出了一种数据中心弹性光网络专用保护优化方法。仿真结果表明，文章所提专用保护优化方法能够有效降低网络的阻塞率，提高网络资源利用率，解决了网络生存性问题。

Abstract

With the development of big data

cloud services

and artificial intelligence

the optical network is developing towards scale and complexity

which suffers from larger probability of network failure. It is necessary to provide dedicated-path protection for each connection request to reduce the loss caused by the network failures. Therefore

in order to guarantee the network survivability

we propose a dedicated-path protection optimization method to improve the network resource efficiency in elastic optical networks with data centers. The simulation results show that the proposed dedicated-path protection optimization method can effectively reduce the blocking probability

improve the network resource utilization

and solve the survivability problem of elastic optical networks in data centers.
