现有校园网络基础设施的设计不能有效处理大数据集的传输。这些网络中的性能下降通常是由中间设备引起的-这些设备通过深入检查通过网络的所有流量（包括大数据传输）来执行校园范围的策略。我们正在为我们的校园网络开发软件定义网络（SDN）解决方案，通过动态计算绕过某些中间盒的路由来赠款科学流特权，以避免它们造成的瓶颈。使用SDN控制器提供的全局网络信息，我们正在开发图形数据库方法来计算自定义路径，这些自定义路径不仅绕过中间盒来实现某些要求（例如，等待时间、带宽、跳数），而且还插入逐跳修改分组的规则，以创建标准路由/转发的假象，而不管分组正在被重新路由的事实。在一些情况下，需要使用网络功能虚拟化（NFV）技术（例如，NAT）。为了确保路径计算是在拓扑的最新快照上运行的，我们引入了一种版本控制机制，该机制允许仅在发生“重要”网络更改并由大数据流请求时才进行延迟拓扑更新。
Existing campus network infrastructure is not designed to effectively handle the transmission of big data sets. Performance degradation in these networks is often caused by middleboxes -- appliances that enforce campus-wide policies by deeply inspecting all traffic going through the network (including big data transmissions). We are developing a Software-Defined Networking (SDN) solution for our campus network that grants privilege to science flows by dynamically calculating routes that bypass certain middleboxes to avoid the bottlenecks they create. Using the global network information provided by an SDN controller, we are developing graph databases approaches to compute custom paths that not only bypass middleboxes to achieve certain requirements (e.g., latency, bandwidth, hop-count) but also insert rules that modify packets hop-by-hop to create the illusion of standard routing/forward despite the fact that packets are being rerouted. In some cases, additional functionality needs to be added to the path using network function virtualization (NFV) techniques (e.g., NAT). To ensure that path computations are run on an up-to-date snapshot of the topology, we introduce a versioning mechanism that allows for lazy topology updates that occur only when "important" network changes take place and are requested by big data flows.
