Transition techniques play a vital role during the evolvement process of the Internet from IPv4 to IPv6. However, packet length change during the forwarding process may result in fragmentation and reassembly of a large number of packets, which greatly impacts the forwarding performance. In addition, different Maximum Transmission Unit (MTU) mechanisms of IPv4 and IPv6 have also brought lots of troubles...
With the development of the Internet, the requirement of the unified network computing and storage will continue to increase, which will make the high speed transmitting technology to be adopted more widely. With the advantages of high speed and reliable, InfiniBand technology could load other protocol data units, and bring the convergence of InfiniBand and Ethernet. In this paper the conversion technologies...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
