“…At the same time, we need visibility tools for the operators to troubleshoot when the developers face problems during their experiments. Currently, we have OF@TEIN SDN Experimenter UI from previous work [4] which shows allocated resources and running experiment, and then we also add experiment result visualization based on the specific measurements criteria (e.g., Round-trip time for ping test, maximum available bandwidth for bandwidth measurement experiment, and bit rate and decoded frames for video-streaming experiment). However, sometime the executed experiments and associated visualizations are not running smoothly as expected.…”

One key challenge in operating virtualized Future Internet testbed is how to monitor various experiments running on the top of it. Among multiple visibility levels for resources, flows, and services, flow-centric visibility is becoming crucial. In this paper, in order to monitor lifecycle experiments over OF@TEIN OpenFlow-based SDN testbed, we are working on flow-centric visibility. The main idea behind flow-centric visibility is duplicating specific packets from OpenFlow-enabled switches and redirecting those packets via a visibility fabric. The duplicated and redirected packets are processed to provide basic visualization about flow information. The flow tapping, implemented for the virtual switches of OF@TEIN SmartX Boxes, is preliminary verified by utilizing it to monitor the targeted lifecycle experiments.

“…We are also required to support the users to play with predefined or others tools/scripts for their own experiments. This paper tries to extend our previous 'workflowbased control of experiment' work [3], by implementing the automated resource provisioning (i.e., installation/configuration of utilized resources) and automating the experiment execution via easy-to-use scripting. As a result, we can provide fast and efficient realization of lifecycle experiments over OF@TEIN.…”
