Shahnaza Tursunova, Young-Tak Kim, “A Study on Service Discovery for Web Service based Network Management,” in Proceedings of JCCI’07, PyeongChang, Korea, 03 May. 2007, pp.-.
Abstract This paper reports on a study to investigate service discovery protocols, which can be used for Web Service based Network Management. We took traditional Universal Description, Discovery, and Integration (UDDI) with Web Services, Service Location Protocol (SLP) with Web-based Enterprise Management, and Universal Plug and Play (UPnP), which becomes well-known in […]

Igor Kim, Young Chul Jung, Young-Tak Kim, “Hybrid Admission Control for QoS Support in IEEE 802.11e EDCA,” in Proceedings of KNOM 2007, Jeju, Korea, 26 Apr. 2007, pp.65-70.
Abstract Although IEEE 802.11e provides features of QoS support, strict admission control mechanism is required to control the entrance of new stream into the system to protect QoS of the existing streams. This paper proposes Hybrid Admission Control (HAC), which is implemented in QoS Access Point (QAP) and QoS Stations […]

QiaoKe, Djakhongir Siradjev, Jeongki Park, Young-Tak Kim, “Source-End DDoS Protection with IXP2400 Network Processor,” in Proceedings of KNOM 2007, Jeju, Korea, 19 Apr. 2007, pp.-.
Abstract In this paper we design and implement a source-end DDoS protection system on IXP2400 network processor which monitors traffic from the source subnetwork and polices traffic at the source without affecting the traffic from other networks. Having started from the usual packet forwarder application, we designed three additional modules […]

서종철, 김영탁, “다수의 도메인 네트워크를 경유하는 품질보장형 DiffServ-over-MPLS 서비스 제공을 위한 WBEM/CIM 기반의 연결관리기법,” in Proceedings of KICS 2006, 제주, 대한민국, 05 Jul. 2006, pp.744-744.
Abstract 다수의 autonomous system (AS) 도메인 네트워크들을 통하여 품질보장형 차별화 서비스를 제공하기 위해서는 inter-AS 트래픽 엔지니어링 기술이 필수적으로 요구된다. Inter-AS 트래픽 엔지니어링을 위해서는 MO (Managed Object) 가 여러 개의 도메인 네트워크에서 공유될 수 있도록 표준화 되어야 하며 다른 네트워크 operator 들이 쉽게 접근할 수 있어야 한다. 본 논문에서는 inter-AS 간의 […]

Young-Chul Jung, Timur Allamiyarov, Jong-Cheol Seo, Young-Tak Kim, “SIP and RSVP-TE for QoS-guaranteed DiffServ Provisioning,” In Proceedings of KICS 2005, YongPyong, Korea, 30 Jun. 2005, pp.365-365.
Abstract For the past decade, a lot of research has been dedicated to provide Quality of Service (QoS) for multimedia communications. In order to provide QoS-guaranteed realtime multimedia services on IP-based networks, tightly interactions between session and connection management, is inalienable. The model, which provides both session and connection […]

윤승훈, 김영탁, “ForCES 구조에서 빠른 Link Failure Detection을 위한 Network Time Protocol과 Bidirectional Forwarding Detection의 적용 방안,” In Proceedings of KICS 2006, 제주, 대한민국, 05 Jul. 2006, pp.743-743.
Abstract 대용량 분산 패킷 처리가 가능한 차세대 인터넷 라우터의 기능 구현을 위하여 IETF에서는 ForCES (Forwarding and Control Element Separation) 기능 구조가 제안되었다[1, 2]. 하지만, IETF에서 제안된 ForCES 기능 구조에서는 link를 감시하고 제어하는 기능에 대해선 정의 되어 있지 않다. 따라서 link의 상태를 detection하고 관리하기 위한 방법이 필요하다. 최근에 IETF에서 forwarding plane […]

Djakhongir Siradjev, Seung-Hun Yoon, Sang-Heon Shin, Young-Tak Kim, “ForCES-based Distributed Packet Processing in Next Generation IP-GMPLS Router using Network Processor,” In Proceedings of KNOM 2005, Seoul, Korea, 29 May. 2005, pp.279-285.
Abstract This paper proposes a ForCES-based distributed packet processing and its control plane architecture in next generation IP/MPLS router using network processor. In the proposed IP/MPLS router architecture, we explain the implementation approaches for ForCES-based separated control plane functions, DiffServ-over-MPLS packet processing for QoS-guaranteed differentiated service provisioning, hierarchical traffic grooming, […]

Djakhongir Siradjev, Young-Tak Kim, “Fast Range Classification on Network Processor,” In Proceedings of IEMEK 2006, Daegu, Korea, 12 May. 2006, pp.2-5.
Abstract Packet classification is one of the key functions for applications that require recognition of separate packet flows such as firewalls, intrusion detection systems, and differentiated services. This paper proposes a scalable classifier architecture that does not require specific hardware search engines and can be implemented using network processor. The […]

Ivan Gurin, Young-Tak Kim, “Packet Scheduler for DiffServ-over-MPLS on Intel IXP2400 Platform,” In Proceddings of UECSM 2005, Daegu, Korea, 10 Nov. 2005, pp.149-155.
Abstract In this paper we introduce our model of DiffServ-over-MPLS packet scheduling on Intel IXP2400 network processor platform and the design of basic DiffServ-over-MPLS functionality. This application is expected to be used as the basis for further research on concerned networking technologies, and exploiting network processor computational power and flexibility […]
