In Chapter 3, we show the DPI Abstract— Due to the development of the mobile network platform that is developed in Korea. Lastly, the conclusion and and the wide use of mobile devices, mobile traffic has contribution will be presented in Chapter 4. significantly increased. Most advanced countries including Korea have developed various technologies to reduce heavy mobile traffic. This research has developed and utilized the DPI (Deep Packet Inspection) platform that has been considered as a solution for enhancing the mobile traffic flow. In this paper, the hardware and software components of the platform are described with its four utilization fields. Keywords—Deep Packet Inspection, Mobile Traffic, High-speed Internet Traffic Control and Analysis Platform (HITCAP), Data Traffic Control Fig. 1 Mobile Data Traffic Profile (Europe, Wi-Fi) I. INTRODUCTION (Source: Sandvine, 2012) ECENTLY, mobile traffic has increased due to the R advance of mobile telecommunication technologies and II. RELATED WORKS the advent of the various connected devices. According to the research of Sandvine company, mobile data has the peak traffic A. Deep Packet Inspection around 2 PM in Europe (See Fig. 1) [1]. The Internet service The DPI technology was first introduced for network providers (ISP) and the mobile carriers spend their network security. As the representative security technology prior to the management budgets by decreasing the traffic in congestion introduction of DPI, Stateful Packet Inspection (SPI) time [2]. Therefore, the mobile carriers need to adopt the technology was widely used, which is the technology for Network Intelligence Technology for efficiently managing and detecting abnormal packets by inspecting the packet headers distributing the mobile traffic that constantly occurs in the (Layer 2-4) [6]. However, SPI is not able to detect new mobile network under limited spectrum resource environment network attacks, for example, NIDS Evasion and DDoS. [3, 4]. Accordingly, DPI was introduced and it became a new In order to enhance the mobile traffic situation in Korea, the technology to inspect the Payload, which means the contents of Electronics and Telecommunications Research Institute (ETRI) packets, by inspecting the entire layer of packets (Layer 2-7) has developed the Deep Packet Inspection (DPI) platform as (See Fig. 2) [7]. These days, the network enterprises embed the part of the development of Network Intelligence Technology technology into their equipment. The DPI provides operators [5]. This research describes the DPI platform which is with visibility into the data traffic needed to enable new service developed in Korea in respect to software and hardware. In models and pricing plans and to support new architectures like Chapter 2, we reviewed the concept of DPI and the current software-defined networks (SDNs) [8]. B.

CONCLUSIONS AND FUTURE WORKS Due to the dramatic increase of data traffic in mobile networks, lots of service providers are adopting the DPI equipment for securing the visibility of the data traffic. The DPI technology has become one of the key network intelligent technologies in order to manage the data traffic. Recently, Sandvine and Cisco, which are major network equipment enterprises, have released DPI equipment. The ETRI has also developed the DPI platform, i.e., HITCAP, as the representative Korean DPI platform.

  • Government-Wide Cyber Security
    White Paper Government-Wide Cyber Security Leveraging Network Intelligence Technology April 2009 Enabling True Network Intelligence Everywhere White Paper Government-Wide Cyber Security Executive Summary Governments and multi-government organizations can better support IT network security across applications and government functions with a common technology platform leveraging Network Intelligence building blocks. IT security continues to be the greatest challenge facing government CIOs worldwide. Most experts agree that governments require stronger partnerships between the public and private sectors for both better protection of government IT systems from intruders and for greater visibility into operators’ network traffic to fight crime. However, government systems and intelligence activities constitute a very sensitive information environment. Governments must proceed with caution when forming technology partnerships for hardening their IT network security. Melissa E. Hathaway, who in February 2009 was named to be the Obama Administration’s top cyber security official, points out how government IT organizations should be asking questions such as: Who designed the security technology? Who built the technology? Who operates and maintains the technology? Who upgrades the technology? Who retires the technology?1 Commercial-Off-The-Shelf (COTS) products are not always suited for government network security needs. Governments can better support network security across applications and government functions with a common technology platform consisting of reusable technology building blocks. Such a global approach would enable government organizations to control the development, performance and maintenance of security applications, while preserving the confidentiality of security mechanisms for detecting cyber criminals and protecting information. Qosmos Network Intelligence provides this capability. Qosmos Network Intelligence provides this capability with technology to extract detailed IP metadata from network traffic.

  • Understanding Packet Voice Protocols
    Understanding Packet Voice Protocols Introduction Over the past decade, the telecommunications industry has witnessed rapid changes in the way people and organizations communicate. Many of these changes spring from the explosive growth of the Internet and from applications based on the Internet Protocol (IP). The Internet has become a ubiquitous means of communication, and the total amount of packet-based network traffic has quickly surpassed traditional voice (circuit-switched) network traffic (DataQuest, 1998). In the wake of these technology advancements, it has become clear to telecommunications carriers, companies, and vendors that voice traffic and services will be one of the next major applications to take full advantage of IP. This expectation is based on the impact of a new set of technologies generally referred to as voice over IP (VoIP) or IP telephony. VoIP supplies many unique capabilities to the carriers and customers who depend on IP or other packet-based networks. The most important benefits include the following: · Cost Savings: By moving voice traffic to IP networks, companies can reduce or eliminate the toll charges associated with transporting calls over the public switched telephone network (PSTN). Service providers and end users can also conserve bandwidth by investing in additional capacity only when it is needed. This is made possible by the distributed nature of VoIP and by reduced operations costs as companies combine voice and data traffic onto one network. · Open Standards and Multivendor Interoperability: By adopting open standards, both businesses and service providers can purchase equipment from multiple vendors and eliminate their dependency on proprietary solutions. · Integrated Voice and Data Networks: By making voice "just another IP application," companies can build truly integrated networks for voice and data.

Nevertheless, the question of whether network operators should be prevented from blocking or prioritising certain network traffic or traffic from particular sources is a significant one for a wide range of stakeholders in the digital networked economy. Network operators contend that the build costs for the next generation of networks are so high that they must be permitted to monetise their control over this infrastructure as efficiently as possible. Meanwhile, an eclectic mix of interests including content and service providers, free speech and special interest groups and entertainers, argue that net neutrality re- gulation is necessary to guarantee that the Internet’s core values and social utility are preserved. This article offers an introduction to net neutrality from a UK perspective. The authors explain the technical, commercial, political and legal considerations that underpin the issue and suggest that, whilst net neutrality regulation in its strongest incarnation is not practical or desirable, a level of regulatory action designed to enhance the choices of end users is the best way forward. ª 2006 Baker; McKenzie LLP.
