In this paper, we describe the concept of utilizing packet tracing and collection for 3rd-party packet-precise inspection to assist the secure operation of SDN-enabled multisite cloud environment. The proposed packet tracing and collection is designed and prototyped by utilizing open-source IO Visor project's tools. To verify its feasibility for remotely distributed multiple boxes, we apply it to...
Resource-level monitoring and visualization are important operation activities for OF@TEIN (OpenFlow @ Trans-Eurasian Information Network) SDN-enabled multi-site cloud. The SDN/Cloud integrated environment demands considerably different resource-level visibility solution from traditional ones. A distinctive, component-based, data-oriented approach is required for resource-level visibility of OF@TEIN...
In OF@TEIN (OpenFlow @ Trans-Eurasian Information Network) SDN-enabled distributed cloud testbed, the resource-level visibility is extremely critical to ensure high availability of Physical+Virtual resources and identifying key performance bottlenecks which can significantly degrade testbed operation. Among multiple visibility levels for resources, flows and services, resource-level visibility is...
