【摘要】：針對電力企業(yè)數(shù)據(jù)業(yè)務(wù)流量爆炸性增長所引發(fā)的骨干網(wǎng)絡(luò)帶寬資源瓶頸問題,在對國家電網(wǎng)公司光傳輸網(wǎng)(optical transport network,OTN)大容量骨干傳輸網(wǎng)絡(luò)承載業(yè)務(wù)需求分析基礎(chǔ)上,從頻譜管理方法、交叉連接設(shè)備、混合線速傳輸、控制平面等方面出發(fā),探索FlexGrid技術(shù)在電力通信網(wǎng)絡(luò)中的應(yīng)用模式,可為電力通信骨干網(wǎng)絡(luò)提供光層粒度的精細(xì)劃分與動態(tài)調(diào)整能力。在此基礎(chǔ)上,提出在多種約束條件下根據(jù)頻譜資源利用度動態(tài)調(diào)節(jié)調(diào)制的信道資源管理方法,可有效改善現(xiàn)有骨干傳輸網(wǎng)絡(luò)采用的固定帶寬分配和管理模式造成網(wǎng)絡(luò)靈活性差,帶寬資源利用效率低下的現(xiàn)狀。
[Abstract]:Aiming at the bottleneck of backbone network bandwidth caused by explosive growth of data traffic in electric power enterprises, this paper analyzes the demand of large capacity backbone transmission network of optical transmission network optical transport network of State Grid Company. From the aspects of spectrum management, cross-connection equipment, hybrid line speed transmission, control plane and so on, this paper explores the application mode of FlexGrid technology in electric power communication network. It can provide fine partition and dynamic adjustment ability of optical layer granularity for power communication backbone network. On this basis, a channel resource management method which dynamically adjusts modulation according to the utilization of spectrum resources under a variety of constraints is proposed, which can effectively improve the fixed bandwidth allocation and management mode used in the existing backbone transmission networks, resulting in poor network flexibility. The current situation of inefficient use of bandwidth resources.
