基于控制器集群的SDON多域互联互通技术

SDON multi-domain connectivity technology based on cluster controller

针对软件定义光网络(SDON)多控制域互联互通的需求,在对多控制域信息交互协同控制进行分析研究的基础上,利用负载均衡的思想,提出了一种基于控制器集群的SDON多控制域互联互通架构,包含集群间和集群内两个互联层次。利用集群间控制器迁移和集群内主从控制器切换机制,实现光网络中多控制域间的协同互联和负载均衡,提升网络服务质量。

In order to interconnect for multi-domain software defined optical network （SDON）, this paper pro- poses a controller cluster-based interconnecting framework based on load balancing after the analysis of infor- mation interaction and coordinated control across domains. This framework includes two revels of controller coordination, which are inter-cluster and intra-cluster interconnection. Moreover, migrating the controller be- tween clusters and switching primary and secondary controller of an optical switching equipment achieve the collaborative interconnection and load balancing in multiple domains. It improves quality of service at the same time.
