Although IPv6 protocol has considered and implemented more security mechanisms compared with IPv4, there are still many security threatens in IPv6 networks. Being one of the key protocols in IPv6, the Internet control message protocol (ICMPv6) suffers from severe security risks. In this paper we construct an IPv6 attacking test system H6Proxy exploiting the ICMPv6 unreachable message, which shows...
Researching for practical network communication technology, this paper designs a network communication system running under the C/S (client/server) mode. Based on the socket communication, the network communication part adopts TCP/IP protocol and UDP protocol. By the system, users in LAN could communicate with each other in real time, conveniently and safely, the function of sending instructions and...
It is an important field of research to achieve precise time synchronization with precision time protocol in network. This paper mainly studies the kernel mechanism of synchronizing the clock between the host and slave devices with PTP, on which base the system is designed and realized through software simulation with the programming tool C#. The precision of synchronization reaches one millisecond...
In this paper we present empirical results from a study, examining the effects of environmental diversity on vehicle-to-vehicle link in vehicular ad hoc networks (VANET). And packet loss rate (PLR) and received signal strength indicator (RSSI) of the wireless link are measured. The results of the measurement indicate that environment affects the quality of the wireless link in VANET greatly; the average...
