The demands for reliable large data transfer increases and it becomes more likely to happen soon as the technologies such as optical burst switching (OBS) and high speed TCP mature. In this paper, we consider high speed TCPs over OBS networks. We evaluate variants of high speed TCP over OBS networks; point out a performance problem when these two technologies are combined; propose a transport level solution based on pacing. The effectiveness of the proposed solution is validated through the simulation using the OBS-ns simulator

Recently, there are many paradigms for supporting convergence for both networks and computing. Grid computing offers high levels of computational, storage and network capacity on the wide area environment. Optic based network is a good candidate for supporting the grid application. In this paper, we proposed a novel contention resolution scheme which is differentiated by specific application and their job type for supporting grid services in the OBS network

IEEE 802.16 issued standards for the new PHY and MAC for providing broadband wireless access network. It is characterized by very high data rates and wider range which are different from existing wireless access technologies such as IEEE 802.11 or 3G. Accordingly, the use of IPv6 over IEEE 802.16 network is currently undefined. There are several issues to be considered in deploying IPv6 over IEEE 802.16 networks. Among them, this document will describe issues related to NDP (neighbor discovery protocol) over IEEE 802.16 networks

In this paper, we propose a simple but tough method for confirming response packets to detect DRDoS attack packets. In DRDoS attacks, the victim suffers from reflected response packets from legitimate hosts, and it is difficult to distinguish attack packets from legitimate packets. We focus on the fact that the types of packet used for DRDoS are limited and predictable. Thus, the proposed method uses only a pair of request/response, and does not need complicated state management like the stateful inspection method. We demonstrate that the proposed method can accurately detect DRDoS packets with fewer cost

A critical design issue of TCP is its congestion control that allows the protocol to adjust the end-to-end communication rate to the bandwidth on the bottleneck link. However, TCP congestion control may function poorly in high bandwidth-delay product networks because of its slow response with large congestion windows. In this paper, we propose an improved version of TCP Vegas called quick Vegas, in which we present an efficient congestion window control algorithm for a TCP source. Our algorithm is based on the increment history and estimated amount of extra data to update the congestion window intelligently. Simulation results show that quick Vegas significantly improve the performance of connections as well as remain fair and stable when the bandwidth-delay product increases

Mobile and wireless communications are rapidly developing, "what lies ahead for cellular technology?" published by George Lawton (G. Lawton, June 2005) shows this concern. Binary receiver in wireless fading channels is one of important issues in the digital wireless communications. The error probability of binary in Nakagami-m fading channels was investigated in this paper. In particularly, the application for optimum binary receiver was carefully presented for the so called optimum threshold for an error probability. At the same time, the related Nakagami-m parameter fading channels were also estimated by closed forms, which can be applied to the based estimation for the digital communication systems with various noises. As one application, the error probability was used to estimate the bottom line of binary communication systems. Other digital coding systems are discussed in separated papers

This paper proposes a VPN accelerator board (VPN-AB), a virtual private network (VPN) protocol designed for trust channel security system (TCSS). The TCSS supports safety communication channel between security nodes in Internet. It furnishes authentication, confidentiality, integrity, and access control to the security node to transmit data packets with IPsec protocol. TCSS consists of Internet key exchange block, and security association block, IPsec engine block. The Internet key exchange block negotiates crypto algorithm and key used in IPsec engine block. Security association blocks setting-up and manages security association information. IPsec engine block treats IPsec packets and consists of networking functions for communication. The IPsec engine block should be embodied by HAV and in-line mode transaction for high speed IPsec processing. Our VPN-AB is implemented with high speed security processor that supports many cryptographic algorithms and in-line mode. We evaluate a small TCSS communication environment, and measure a performance of VPN-AB in the environment. The experiment results show that VPN-AB gets a performance throughput of maximum 15.645 Gbps when we set the IPsec protocol with 3DES-HMAC-MD5 tunnel mode
