Internet has played an important part in the success of information technologies. With growing and changing demands, there are many limitations faced by current Internet. A number of network test beds are created for solving a set of specific problems in Internet. Traditionally, these test beds are lacking of large scale network and flexibility. Therefore, it is necessary to design and implement a...
Recently, Cloud Computing is getting considerable attentions not only as the technology trend but also the new business model. Virtualization plays an extremely important role in Cloud Computing. Server virtualization has been achieved using virtualization hypervisor software such as VMware, Xen, and KVM,etc. Virtual Machines (VMs) created by hypervisors share the same physical environment with each...
Based on services-oriented architecture(SOA), perfSONAR is a web service infrastructure. The set of elementary functions have been isolated and can be provided by different services. A primary goal of perfSONAR is to make it easier to detect performance monitoring problems among different network domains. perfSONAR has been widely accepted as one of the web service standards by NRENs (National Research...
Network traffic demands grow explosively from multimedia, point-to-point, and E-Science applications. In order to meet such tremendous growth, optical networks has been introduced for exploring higher bandwidth and better QoS guarantee. Problems arise when integrating the whole new optical infrastructure with current IP backbone, including controlling data path and network management. In this paper,...
With the explosive growth of Internet, various applications are developed. Their common feature is the desire for higher network bandwidth than before. Network backbone has been upgraded from 155 Mbps with ATM technology to Gigabit Ethernet or 10 Gigabit Ethernet to meet this trend. Besides, some next-generation e-science applications such as video streaming, high-quality images, and grid computing...
A human HSMT3 cDNA encoding a homolog of the yeast SMT3, a suppressor of MIF2 mutations in a centromere protein gene, was identified and sequenced. The sequence of 95 amino acids deduced from the human HSMT3 cDNA exhibited 51.1% identity and 69.6% similarity to the yeast Smt3p sequence. The HSMT3 transcripts of 1.35Kb were found to be abundantly expressed in various human tissues.
