CC* Integration: Enhancement and deployment of LDM7 for scientific data distribution

大学大气研究公司通过互联网数据分发系统向其250个联合体成员机构分发来自仪器和模拟的科学气象数据。用于此数据分发的软件程序称为本地数据管理器（LDM）。LDM 6是目前部署的版本，自2003年以来一直在使用。该项目旨在通过利用软件定义网络和OpenFlow技术创建一个更高性能的实时科学数据分发解决方案。该项目旨在（i）在跨校园和区域提供网络后，在多个校园部署LDM 7，并将它们连接到Internet 2上的多点VLAN。snetwork，（ii）为LDM 7添加安全和控制平面的新功能，（iii）将LDM 7与SDN控制器（OESS）客户端集成，以自动向多点VLAN添加/删除VLAN网段，（iv）收集信息并开发工具，以简化VLAN配置，并使用perfSONAR和其他工具测试L2路径连通性和性能，（v）对LDM 7进行广泛的性能和可靠性测试。

The University Corporation for Atmospheric Research (UCAR) distributes scientific weatherdata from instruments and simulations to its 250 consortium member institutions via the InternetData Distribution (IDD) system. The software program used for this data distribution is called Local Data Manager(LDM). LDM6, the current deployed version, has been in use since 2003. This project seeks tocreate a higher performing solution for real-time scientific data distribution by leveraging Software DefinedNetworking and OpenFlow technologies.This project seeks to (i) deploy LDM7 on multiple campuses after provisioningVLANs across campuses and regionals, and connecting them to a multipoint VLAN across Internet2?snetwork, (ii) add new features for security and control-plane to LDM7, (iii) integrate LDM7with an SDN controller (OESS) client for automated addition/deletion of VLAN segments to amultipoint VLAN, (iv) collect information, and develop tools for simplifying VLAN provisioningand testing L2 path connectivity and performance using perfSONAR and other tools, and (v)run extensive tests of LDM7 for performance and reliability.
