Internet evolves into the huge network with new nodes inserted or deleted depending on specific situations. A new model of network topology is needed in order to analyze time-varying Internet more realistically and effectively. In this study the non-monotony models are proposed which can describe topological changes of Internet such as node insertion and deletion, and can be used for predicting its future topology. Simulation is performed to analyze the topology generated by our model. Simulation results show that our proposed model conform the power law of realistic Internet better than conventional ones. The non-monotony model can be utilized for designing Internet protocols and networks with better security.

'Enhanced Cooperation', which was the mandate of Tunis Agenda in 2005, was the product of political compromise after failing to reach a consensus on global internet governance mechanism. In 2012, UN General Assembly decided to establish CSTD 'Working Group on Enhanced Cooperation (WGEC)' to find out what could and should be done to implement the Tunis Agenda. After a first meeting, WGEC sent out a questionnaire to collect extensive opinions from internet communities. Replies to the questionnaire showed a broad spectrum of perspectives on the problem of existing internet governance arrangement and how to improve it. This article analysed different perspectives, based on replies, especially regarding the concept and implementation of the Tunis Agenda, public policy issue and possible mechanisms, and the role of stakeholders including government. The recommendation of WGEC will be submitted to UN GA passing through CSTD and ECOSOC, in 2014, which is expected to have great impact on the future of internet governance.

This study investigates the relationship among interactivity, telepresence, flow, and future behavior intention in internet shopping. Respondents were female consumers age 20 to 30. These consumers are regarded to have experience in internet shopping. 500 samples were used in this research. For data analysis, descriptive statistics, factor analysis, ANOVA, and multiple regression analysis were used for this study. As the result, interactivity, telepresence, and flow affect future behavior intention. Flow is the most influential variable affecting the future behavior intention. It implies that hedonic shopping experience (aroused by flow) can increase the future behavior intention of consumers. Consumers can operate and change the product image with convenience by encouraging interactivity between the internet fashion shopping mall and consumers. Through the technology, the experience 'flow' of consumers can provide a sense of telepresence as if they were shopping in a real store. Consumers may feel unconscious of the passage of time and feel fun, free, and original. Therefore, the internet shopping mall should pay attention to what customers demand and reflect it through e-mail, real time chatting, and text messages. In addition, rich product information such as detailed images should be supplied to help customers visualize looks.

Recently, new network systems have begun to emerge (for instance, 5G, IoT, and ICN) that require capabilities beyond that provided by existing IP networking. To fulfill the requirements, some new networking technologies are being proposed. The promising approach of the new networking technology is to try to overcome the architectural limitations of IP networking by adopting an identifier (ID)-based networking concept in which communication objects are identified independently from a specific location and mechanism. However, we note that existing ID-based networking proposals only partially meet the requirements of emerging and future networks. This paper proposes a new ID-based networking architecture and mechanisms, named IDNet, to meet all of the requirements of emerging and future networks. IDNet is designed with four major functional blocks-routing, forwarding, mapping system, and application interface. For the proof of concept, we develop numeric models for IDNet and implement a prototype of IDNet.

The Internet is becoming increasingly diverse and complex, the needs of user's convenience is also various and increased. The task forces have been working on how to design the future Internet in satisfaction of user's require and mobility management is one of the key issues to be considered. mobility management in the future Internet is still being designed in an "all-in-one" way where all management functions are tightly kept at a single location and this results in cost inefficiency that can be an obstruction to constructing flexible systems. In this paper, we propose a cost-effective function-distributed mobility management scheme that can enable more flexible future Internet construction. Furthermore, we show the effectiveness of our proposed system via a cost analysis and computer simulation with a random walk mobility model.

In this paper, we examine the problems of the current Internet due to the development of network services and the expansion of network bandwidth. The current Internet has been used for a long time because it is composed of TCP / IP, but fundamental problems such as bandwidth, transmission rate, and security have not been solved. Therefore, the future network must be prepared through continuous investment and maintenance. In order to overcome this problem, we will propose a way to overcome the above problems and upgrade by converting the current Internet Protocol into the next generation network. Currently, many researches on next-generation networks have been conducted, but there are not many studies in Korea, and research on next-generation networks will be a very important task for the future development of the Internet service industry at the national level. In this paper, we propose an advanced internet environment through the advantages of various next generation protocols.

Recently, research activities on the future internet are being actively performed in foreign and domestic. In domestic, ETRI and 4 universities are focused on implementation of a testbed for research on the future internet named as 'FiRST(Future Internet Research for Sustainable Testbed)'. In the 'FiRST' project, 4 universities are performing a project in collaboration named as 'FiRST@PC' project that is for an implementation of the testbed using the programmable platform-based openflow switches. Currently, the research on the virtualization of the testbed is being performed that has a purpose for supporting an isolated network to individual researcher. In this paper, we implemented a traffic scheduler for providing QoS by using the programmable platform that performs a hardware-based packet processing and we are implemented a testbed using that traffic scheduler. We perform a performance evaluation of the traffic scheduler on the testbed. As a result, we show that the hardware-based NetFPGA scheduler can provide reliable and stable QoS to virtualized networks of the Future Internet Testbed.

Building a large-scale testbed for Future Internet is very important to evaluate a new protocol and new network architecture designed by clean-slate approach. In Korea, new Future Internet testbed project, called FIRST (Future Internet Research for Sustainable Testbed), has been started since Mar. 2009 to design and test new protocols. This project is working together with ETRI and 5 universities. The FIRST@PC is to implement a virtualized hardware-accelerated PC-node by extending the functions of NetFPGA card and build a Future Internet testbed on the KOREN and KREONET for evaluating newly designed protocols and interesting applications. In this paper, we first briefly introduce FIRST@PC project and explain a 'MAC in IP Capsulator' user-space program using raw-socket in Linux to interconnect OpenFlow enabled switch sites on the KOREN and KREONET. After that, we address test results for TCP throughput performance for varying packet size. The test results show that the software based capsulator can support a reasonable bandwidth performance for most of applications.
