|
摘要
以节点传输(接入)设备和海缆链路的可靠性为评价指标,研究了海底观测网传输网络拓扑结构。根据传输网络结构特性,定义系统、链路、节点传输(接入)设备可靠性,提出了海底传输网络拓扑结构的评价指标以及设计目标,通过计算得出满足要求的若干拓扑结构,并根据计算结果,分析比较各拓扑结构优劣,给出了实际应用中网络拓扑的建议。
The topology of transmission network in a submarine observation network is studied by using the reliabilities of node transmission(access)equipment and submarine cable link as the evaluation specification.According to the structure characteristic of the transmission network,the reliabilities of the system,link and node transmission(access)equipment are defined,and the evaluation specification and design target of the topology in submarine transmission network are put forward.Several topologies which meet the requirements are got through calculation,the advantages and disadvantages of the topologies are analyzed and compared according to the calculated results,finally,the suggestions of the network topology in practical application are put forward.
