CC-NIE Networking Infrastructure: Data Intensive e-Science and SDN at NCSU

北卡罗来纳州州立大学正在部署下一代可扩展网络架构，以支持跨多个学科的教师、员工和学生，这是由NSF CC-NIE网络基础设施增强资助实现的。 这种架构在校园网络的战略点引入了新的设备和流程，并提供了一个多功能的基础设施，以支持e-Science，Computing-in-X和网络研究。 它还利用软件定义网络（SDN）等敏捷技术来满足园区社区当前和未来的需求，同时最大限度地减少资本支出和运营支出。新架构消除了瓶颈，显著增加了几个战略位置的接入层带宽，以支持大数据和高级分析。 该项目利用SDN技术不仅支持网络研究，还构建了一个动态的“虚拟科学DMZ”，为校园研究社区提供增强的网络连接。 这为研究人员在校内和校外交换数据提供了一条优化的、易于采用的路径。 该项目从北卡罗来纳州州立大学的路线图开始，该路线图允许该机构随着数据传输需求的增长和发展，逐步将这些敏捷和高带宽服务扩展到更多种类的校园研究人员。 未来，通过与北卡罗来纳州研究和教育网络合作扩展SDN功能，该机构将为其他地区大学和Internet 2高级第2层研究网络提供SDN支持的带宽，最终提高进行前沿研究的能力。

North Carolina State University is deploying a next generation extensible network architecture in support of faculty, staff and students across multiple disciplines, enabled by an NSF CC-NIE networking infrastructure enhancement grant. This architecture introduces new equipment and processes at strategic points in the campus network, and provides a versatile infrastructure in support of e-Science, computing-in-X, and networking research. It also leverages agile techniques like Software Defined Networking (SDN) to meet current and future needs of the campus community, while minimizing capex and opex.The new architecture eliminates bottlenecks, significantly increasing access layer bandwidth in a few strategic locations, to support big data and advanced analytics. This provides immediate benefit to researchers across diverse disciplines who are generating, processing and sharing more data than ever before.The project leverages SDN techniques not only in support of networking research, but also for the construction of a dynamic "Virtualized Science DMZ" to provide enhanced network connectivity to the campus research community. This provides an optimized, easily adopted path for researchers to exchange data on- and off-campus. This project starts North Carolina State University on a roadmap that allows the institution to extend these agile and high-bandwidth services progressively to a larger variety of campus researchers as data transfer needs grow and evolve. In the future, by extending SDN capabilities in partnership with the North Carolina Research and Education Network, the institution will provide SDN capable bandwidth available to other regional universities and the Internet2 Advanced Layer 2 Research Network, ultimately improving the ability to conduct leading edge research.
