With the growth of network traffic volume, link congestion cannot be avoided efficiently with conventional routing protocols. By utilizing the single shortest‐path routing algorithm from link state advertisement information, standard routing protocols lack of global awareness and are difficult to be modified in a traditional network environment. Re...

An Internet eXchange Point (IXP) is a central aggregation point where Internet Service Providers interconnect with each other using the Border Gateway Protocol (BGP) to peer with Autonomous System (AS). An IXP is also the most critical part of the Internet’s infrastructure. By incorporating Software Defined Network (SDN) technology, Software Define...
Article
In a multi-tenancy SDN environment, physical devices such as switches are shared among tenants. In addition to a centralized controller, each tenant has his own controller that manages resources allocated to the tenant. Hence, the centralized controller performs SDN resource virtualization among tenants and acts as proxy between physical resources...
Chapter
Many important societal activities are global in scope, and as these activities continually expand world-wide, they are increasingly based on a foundation of advanced communication services and underlying innovative network architecture, technology, and core infrastructure. To continue progress in these areas, research activities cannot be limited...
Conference Paper
Recently, the Future Internet technology becomes a popular research topic. To solve the problems caused in traditional network, most researchers propose various new network architectures. One of the famous architectures is Software-defined network (SDN), which can help users develop their own strategies freely without the limited functions on physi...
Article
Internet has played an important part in the success of information technologies. With the growing and changing demands, there are many limitations faced by current Internet. A number of network testbeds are created for solving a set of specific problems in Internet. Traditionally, these testbeds are lacking of large scale network and flexibility....
Conference Paper
Due to rapid development of Internet, the amount of users around the globe is fast-growing in the past 30 years. It leads to the appearance of many problems, such as lack of IPaddresses, worse quality of service, and so on. In order to resolve these problems, many researchers start to design and implement innovative network architectures, which we...
Conference Paper
Large scale data intensive science requires global collaboration and sophisticated high capacity data management. Traditionally, mismatches between the requirements of large scale science and the restrictions of generally deployed networks have been problematic. However, the emergence of more flexible networking, for example, using techniques based...

Article
In part because of the limitations of the TCP/IPprotocols used by the current Internet, the Future Internet has become an attractive network research topic. Recently, several projects focused on the Future Internet have been launched around the globe based on the Open Flow platform, such as those that are part of the GENI project in the U.S., the O...
Article
Defender Cloud is a cloud based backbone network defending system having full scope over the whole backbone network. Rather than detecting suspicious network activities on a local area network, it collects and integrates the flow data from all connecting members and all entrances of a backbone network. After analyzing by a proposed cloud based dist...
Article
Recently, Cloud Computing is getting considerable attentions not only as the technology trend but also the new business model. Virtualization plays an extremely important role in Cloud Computing. Server virtualization has been achieved using virtualization hypervisor software such as VMware, Xen, and KVM,etc. Virtual Machines (VMs) created by hyper...
Article
Currently, support for digital media is one of the fastest growing requirements of the Internet as demand transitions from services designed to support primarily text and images to those intended also to support rich, high quality streaming multi-media. In response to the need to address this important 21st century communications challenge, an inte...
Article
The concepts of cloud computing and Internet applications have expanded gradually and have become more and more important. Researchers need a new, high-speed network to build experimental environments for testing new network protocolswithout affecting existing traffic. In this paper, we describe a way to integrate NetFPGA platform, OpenFlow concept...
Article
Alarm Notification is a service that addresses devices and users with messages to be processed immediately or at a specific time. In this paper, we propose an efficient alarm notification algorithm for earthquake early warning system in Taiwan. Due to the lack of multicast support in the general IP network, we try to deliver notification messages t...
Conference Paper
Due to the rapid development of Internet, there are extensive amount of applications that require fast and stable network communication. However, the infrastructure of Internet is limited by TCP/IP protocol. The Future Internet has become a hot network research topic, such as GENI project in U.S. and FIRST project in Korea. Most of these projects a...
Conference Paper
This study designs and implements a cross-platform, cross-domain P2P multimedia sharing system in the Taiwan Advance Research and Education Network. The system allows users to easily access the multimedia resources of the entire network from any network node, and all multimedia providers can share local multimedia resources from any location on the...
Conference Paper
Based on services-oriented architecture(SOA), perfSONAR is a web service infrastructure. The set of elementary functions have been isolated and can be provided by different services. A primary goal of perfSONAR is to make it easier to detect performance monitoring problems among different network domains. perfSONAR has been widely accepted as one o...
Conference Paper
Network traffic demands grow explosively from multimedia, point-to-point, and E-Science applications. In order to meet such tremendous growth, optical networks has been introduced for exploring higher bandwidth and better QoS guarantee. Problems arise when integrating the whole new optical infrastructure with current IP backbone, including controll...
Conference Paper
With the explosive growth of Internet, various applications are developed. Their common feature is the desire for higher network bandwidth than before. Network backbone has been upgraded from 155 Mbps with ATM technology to Gigabit Ethernet or 10 Gigabit Ethernet to meet this trend. Besides, some next-generation e-science applications such as video...
Conference Paper
With the evolution of technology, it has been a long- term mission for governments to always conform its own national-wide research network backbone to e-Science research applications. The Taiwan Advanced Research and Education Network (TWAREN) not only plays the role of a research network but also offers commodity Internet to universities and rese...
