【摘要】：基于高性能云服務(High Performance Cloud Services, HPCS)架構的遙感應用系統(tǒng)旨在將遙感信息產(chǎn)品通過統(tǒng)一快捷有效的方式提供給用戶。HPCS架構通過高性能集群實現(xiàn)高性能計算,同時通過“云中心-云端”通信對外提供云服務。在基于HPCS架構的遙感應用系統(tǒng)中,系統(tǒng)程序可能分布在不同云中的計算節(jié)點上,因此必須解決系統(tǒng)通信問題以滿足遙感應用系統(tǒng)的低耦合性、插件式需求。 本文對基于HPCS架構的遙感應用系統(tǒng)中的消息通信進行了設計與實現(xiàn)。根據(jù)低耦合性、插件式的系統(tǒng)需求,利用Windows通訊接口(Windows Communication Foundation,WCF)對云內(nèi)部高性能集群進行統(tǒng)一的配置管理以及監(jiān)控；根據(jù)云端與云中心的異構關系以及潛在的離線需求,利用微軟消息隊列(Microsoft Messaging Queue, MSMQ)設計云與云之間的通信；以及為了保障訂單的穩(wěn)定性,對下單以及訂單的查詢采用MSMQ設計,為了實現(xiàn)生產(chǎn)服務器和運行管理服務器的低耦合性,兩者之間的通信均采用WCF進行設計。 在基于HPCS架構的遙感應用系統(tǒng)的消息通信開發(fā)中,云內(nèi)集群的通信采用面向服務思想,解決了高性能集群內(nèi)部的低耦合,插件式需求；云之間的通信滿足了系統(tǒng)的可擴展性和可用性要求；遙感產(chǎn)品生產(chǎn)流程中的通信滿足了遙感產(chǎn)品的實現(xiàn)生產(chǎn)的方式的多樣性需求。
[Abstract]:The remote sensing application system based on high performance cloud service (High Performance Cloud Services, HPCS) architecture aims to provide remote sensing information products to users in a unified, fast and effective way. HPCS architecture realizes high performance computing through high performance cluster. At the same time through the "cloud center-cloud" communications to provide cloud services. In the remote sensing application system based on HPCS architecture, the system program may be distributed on computing nodes in different clouds, so it is necessary to solve the problem of system communication to meet the low coupling and plug-in requirements of remote sensing application system. In this paper, the message communication in remote sensing application system based on HPCS architecture is designed and implemented. According to the requirement of low coupling and plug-in system, the Windows communication interface (Windows Communication Foundation,WCF) is used to manage and monitor the high performance cluster in the cloud. According to the heterogeneous relationship between cloud and cloud center and the potential offline requirements, Microsoft message queue (Microsoft Messaging Queue, MSMQ) is used to design the communication between cloud and cloud. In order to ensure the stability of the order, MSMQ is used to design the order and order query. In order to realize the low coupling between the production server and the operation management server, the communication between the two is designed by WCF. In the development of message communication in remote sensing application system based on HPCS architecture, the communication of cloud cluster adopts service-oriented thought, which solves the low coupling and plug-in requirement of high performance cluster. The communication between the clouds meets the requirements of scalability and availability of the system, and the communication in the production process of remote sensing products meets the diverse requirements of the ways in which remote sensing products can be produced.
