Integrated Signalling for All-IP Convergence Network Research
(Security/QoS/Mobility/Connection/VPN/Emergency Call) Technology
We are developing a Fixed Mobile Convergence (FMC) Network Layer-based Integrated Signaling System Technology that is optimized for the IP packet exchange, which is designed to eliminate the unnecessary complexity of the features of the IP Network Technology due to its imperfect evolution and offer multi-media all-IP mobile communication service .
To compensate the limitation of the current IP Network technology and guarantee a high quality FMC service, we are developing an Integrated Signaling technology that can guarantee end-to-end Seamless Secured Service Continuity on all IP service sessions without using a SIP or IMS-based control signal.
Through the Integrated Signaling technology, we can enable the following features to guarantee a secure FMC communication without IPsec, to allow Global IP session mobility control independent of the access technology (WiFi, HSDPA, LTE, 4G, etc.), to establish a multimedia FMC Smart Work environment, just as in LAN environment without any remote VPN protocol, to offer various CUG services without any separate application software, to guarantee a real-time Mobile VPN environment to mobile users, and to guarantee end-to-end QoS by interacting with LISP-based routers.

Development of Next Generation Fixed Mobile Convergence Gateway Technology
As the diverse converged services are emerging, networks evolve towards All-IP based fixed-mobile converged networks too.
We are developing a fixed mobile convergence gateway(C-GW) to provide seamless mobile IPTV services through the next generation network, where multi mode smart terminals move across diverse access networks. The C-GW provides various functions such that mobility, multicast, QoS mapping and authentication. Also, we are developing VMR(Vehicle Mobile Router) and MCP(Mobile Control Platform). The mobile platform can support IP based seamless mobility between heterogeneous networks.
With researches and developments of these key technologies we are getting the initiative in the next generation network equipments market and helping domestic industry. Also, we are not only trying to acquire intellectual properties but also actively contributing to international standardization meetings.

Development of Smart Border Router for Enterprise
We are developing a smart border router(SBR) for enterprise networks, based on OmniFlow technology. OmniFlow is a circuit-like IP delivery technology providing QoS, security, and routing control per flow using L2~L7 information. The SBR can understand applications, subscribers, policy, and furthermore, dynamic flow behavior changes.
It enforces proper traffic management actions based on those awareness. Also, we are developing adaptive flow translation and flow control protocol to propagate traffic management information to the legacy network to achieve end-to-end policy based QoS guarantee.
We can aggressively use this capability to solve a wide range of network problems, application-aware routing, address hiding and privacy protection, threat mitigation, closed and semi-porous P2P networks and so on.

Development of Application Service Aware Network Switch and Platform
In 2008, Korea became the first country in the world to commercialize a Quality Assurance QoS Router family that guarantees communication quality per service session to prepare for the age of communication/broadcast convergence service a part of the BcN Project.
Flow-aware networking technology, obtained through the development of flow-based QoS router, is a world-leading technology that is emerging as a key component in the era where broadcast/communication convergence services, such as IPTV, VOIP, and etc. are becoming popular. Therefore, a situation-aware service switch that classifies IP packets into different sessions according to the packets' contents, and enables Static & Dynamic contents switching and load-balancing of network, media server and VPN traffics using ETRI's Flow-based QoS technology, is an essential piece in the next-generation network equipment market.
Managed network equipment using Flow-based quality assurance technology Through the joint research between ETRI and Ericsson-Redback to develop the Managed network equipment, which utilizes the Flow-based quality assurance technology, ETRI will produce a network equipment total solution and will attempt to enter into the foreign market by using the marketing capability and marketing network of a global company.

Development of Scalable Micro Flow Processing Technology
As computers are closely combined with networks, it necessitates that personalized services and guaranteed QoS of convergence services should be implemented in a cost effective way. These services involve the strict management of huge number of flows that have never been imagined before, including the status of the connection of the flows. Furthermore, each flow is required to be classified over whole protocol layers up to L7, not confined to traditional network layers of L2 to L3. Eventually, those requirements drive us to develop an OmniFlow Processor.
The OmniFlow Processor inspects the status of the connection of all the packet flows through physical links using SI(Stateful Inspection) and DPI(Deep Packet Inspection), which must be very useful to predict DoS. In addition to process multiple protocol layers required of L3 router and L2 switch, it has an ability to distribute the power of packet processing to each protocol layer flexibly in proportion to the performance required, which is called as a scalable layer-packet processing. Most of all, it has a remarkable traffic control function to include traffic congestion control and connection management for several million number of packet flows per link.
The OmniFlow Processor coupled with General Purpose Processors expands its application area of a mere router to L7 systems such as a fire wall and web switch etc. The integrated devices provide a way to easily develop upper layer applications by using the same software development platform as general CPUs.
Development of Flow Processing Engine for Supplying Telecommunication Equipments
This project is to develop a next-generation software development environment to boost the network equipment industry. Vitalizing the domestic network equipment industry by overcoming the weak infrastructure in developing next-generation networking equipments through the development of a Software Development Kit (SDK) based on OmniFlow for high quality personalized service is the project’s main purpose.
The rapid growth in various multimedia convergence service demands the necessity of accurate analysis and control of the network traffic. To meet this demand, Flow technology and Deep Packet Inspection (DPI) technology are emerging as the solution; however, we do not have a Flow Processor technology that supports policy control per individual user yet.
Therefore, providing a general-purpose development environment for the next-generation network equipment that requires detailed QoS control and traffic control for traffic exchange, security control for VPN, and etc based on in-depth analysis capability is a key factor in promoting the domestic network industry.
Through the project we can expect the following contributions on the network industry:
By supporting High-level Software Development Environment for the use of OmniFlow Process, we expect the network equipment manufacturing companies to occupy the market share in advance or increase their market share by rapidly developing new personalized business models.
- Provide customized solution that meets the needs of the user, company, network and content provider, and government.

- Enable quick responses for future services, such as web-based video service.
- Provide various business application services for company intranet
