Signaling Technogies to Support QoS in IPv6-Based NGN
Found in: Future Generation Communication and Networking
By Gyu Myoung Lee, Jun Kyun Choi, Hyoung Jun Kim
Issue Date:December 2007
pp. 553-556
For emerging IPv6-based Next Generation Network (NGN), this paper describes the needs and applications of IPv6 signaling to support Quality of Service (QoS). In particular, we identify several IPv6 features for QoS signaling. Then, we present QoS provision...
Performance of a Partial Burst Retransmission Mechanism in OBS Networks
Found in: Networking and Services, International conference on
By Tai-Won Um, Jun Kyun Choi, Seong Gon Choi, Won Ryu
Issue Date:July 2006
pp. 108
We investigate the effects on performance of using a partial retransmission mechanism in Optical Burst Switched (OBS) networks. In our scheme, the lost segments of a burst are retransmitted in the OBS layer. We also propose an optical resource reservation ...
Centralized Resource Allocation for Time-Slotted OBS Networks
Found in: Networking and Services, International conference on
By Tai-Won Um, Jun Kyun Choi, Seong Gon Choi, Won Ryu
Issue Date:July 2006
pp. 40
This paper proposes a centralized control architecture and a time-slot assignment procedure for time-slotted optical burst switched (OBS) networks in which ingress OBS nodes request time-slots necessary to transmit optical bursts, and a centralized control...
Improving Energy Saving in Time-Division Multiplexing Passive Optical Networks
Found in: IEEE Internet Computing
By S.H.S. Newaz,Angel Cuevas, Gyu Myoung Lee,N. Crespi, Jun Kyun Choi
Issue Date:January 2013
pp. 23-31
This article proposes a time-division multiplexing passive optical network (TDM-PON) architecture in which optical network units (ONUs) enter active mode only when the optical line terminal has traffic to deliver. The authors use a hybrid ONU (H-ONU) equip...
Abstract state machine based next generation IPv6 network
Found in: Proceedings. ITCC 2005 International Conference on Information Technology: Coding and Computing
By Dipnarayan Guha,Jun Kyun Choi
Issue Date:October 2012
pp. 787,788
We show the design of a network processing system in an IPv6 based media gateway based on abstract state machine (ASM) logic and show how the design features may help in scalability realization for end-to-end QoS issues in next generation networks. The nov...
A Study of Flow-based Traffic Admission Control Algorithm in the ATM-based MPLS Network
Found in: Information Networking, International Conference on
By Gyu Myoung Lee, Jun Kyun Choi
Issue Date:February 2001
pp. 213
This paper presents the Differentiated Services (DiffServ) over ATM based Multiprotocol Label Switching (MPLS) core network architecture. This network supports the Integrated Services (IntServ) as well as DiffServ through ATM shortcut connection or MPLS la...
Proactive crossover router discovery with FMIPv6
Found in: Proceedings of the international workshop on Mobility management and wireless access (MobiWac '06)
By Dipnarayan Guha, Doan Huy Cuong, Hyoung Jun Kim, Jin Ho Hahm, Jun Kyun Choi, Jung Soo Park
Issue Date:October 2006
pp. 104-107
This paper presents an enhanced fast handover scheme in Mobile IPv6 named Cross based Fast handover Mobile IPv6 (X-FMIPv6). We propose Proactive Crossover Router Discovery scheme that allow us to locate Crossover Router in advance, before MN actually makes...
QoS Mapping over Hybrid Optical and Wireless Access Networks
Found in: Evolving Internet, International Conference on
By Jongmin Lee, S. H. Shah Newaz, Jun kyun Choi, Gyu Myung Lee, Noel Crespi
Issue Date:August 2009
pp. 139-141
In this paper, we propose a mechanism to provide Quality of Service (QoS) consistency over hybrid optical and wireless access networks. The proposed scheme utilizes QoS allocations by considering heterogeneous wireless service flows in the Passive Optical ...
