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...
Visibility measurement and associated visualization are essential for monitoring the operation of emerging converged software-defined infrastructure (SDI). However, most of existing monitoring tools are not yet ready to cover systematically whole visibility workflow. Thus, in this paper, we present an integrated design for multi-layered visibility workflow, denoted as 'SmartX MultiView Visibility...
Infrastructure visualization based on monitored resource status is essential for the effective operation of modern SDN (Software-Defined Networking)-enabled cloud. More specifically, collecting and visualizing visibility information about both physical & virtual (p+v) types of resources is one of key requirement for multi-site cloud operators. However, most existing visualization tools fall short...
In recent years, there have been an increasing number of attacks on networks, such as the distributed denial-of-service attack. However, the traditional network is not sufficiently flexible to control the huge amount of traffic that now passes through an intrusion detection system. With SDN, which separates control planes and data planes for programmability, elasticity, and simplicity, it becomes...
This paper shows a prototyping and operating effort for a federated multisite SDN-Cloud playground that leverages open-source software such as OpenStack cloud, ONOS SDN controller, and Quagga router. A SDN-based federation possibility for distributed multisite cloud is verified by providing an open playground over three international sites under separate administrative domains.
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...
The lifecycle management of service realization is very challenging. With virtualized playgrounds over Future Internet testbeds, the lifecycle experiments could be easily exercised so that all tasks and responsibilities are well-defined for entire experiment stages among developers and operators. Also, the dynamic provisioning of hyper-convergent compute/networking/storage resources is appropriately...
Managing the lifecycle of service-realization experiments in Future Internet testbed environments is very challenging due to the unbounded scope of user-driven experiments. The lifecycle of experiments should be carefully designed and managed among users and operators so that tasks and responsibilities are well-defined for all experiment stages. The states of involved resources should also be appropriately...
The Future Internet architecture shall be advanced and flexible with regard to service requirements. The new paradigm, called as Software-Defined Networking (SDN) is an architecture for enabling rapid innovation while hiding much of the complexity on the networking design. SDN is a promising solution for network virtualization that decouples control from forwarding or data plane. SDN can be implemented...
TCP/IP (IPv4) protocol standard which had been used over twenty years can't handle Internet network growth in the coming future, so a new protocol standard, IPv6 or IP Next Generation (IPng) has been developed. Because the IPv6 can't be implemented directly to replace IPv4, the transition mechanisms are needed, such as Dual IP Stack, Protocol Translation, and Tunneling. The IPv6 Tunnel Broker is one...
