内容梗概 (abstract) Each application running on a network infrastructure may have different requirements. For example, the secure shell protocol requires as little latency as possible, while the file transfer protocol requires more bandwidth for faster file transfer. To achieve the best performance, the underlying network infrastructure should be able to take the requirements of each application into account and optimize its services accordingly. As network usually has multiple paths from one point to the other, each performs differently. One path may provide higher bandwidth while the other may provide smaller latency.

With Software-defined Networking (SDN) [1], it is possible to dynamically control routes (flows) in the network. Using an SDN implementation such as OpenFlow [2], it is now possible to implement application-aware networking without being limited by traditional paradigm of network analysis, which relied on line-rate packet analysis. [3]

Overseer is our proposed solution to take advantage of the aforementioned property of network using SDN [4]. It is a bandwidth and latency aware OpenFlow controller. It exposes APIs to let network monitoring tools such as Overlord [4] report current status of the network and let applications define flow preference for each connection. Overseer then uses this information to determine a route for each connection accordingly.

In this demo, we will demonstrate the practicality of bandwidth and latency aware network by deploying Overseer on PRAGMA-ENT, a global scale OpenFlow testbed. We will also demonstrate Overseer performance compared to the traditional routing mechanism with minimal spanning tree.
