Network Function Virtualization (NFV) brings a cloud service automation paradigm to demand-driven elastic flexing of infrastructure resources. Thus, it is essential to characterize the impact of hardware and virtualization options on the virtual network function (VNF) performance, and on the load on underlying infrastructure. In this paper, we present VNF(More)
Malicious website attacks including phishing, malware, and drive-by downloads have become a huge security threat to today's Internet. Various studies have been focused on approaches to prevent users from being attacked by malicious websites. However, there exist few studies that focus on the prevalence and temporal characteristics of such attack traffic. In(More)
OBJECTIVE To highlight concepts critical to achieving successful diagnosis and endoscopic therapy for lateral recess of the sphenoid sinus (LRSS) lesions, operative techniques, and avoiding complications in the treatment were discussed. METHOD Pathology within a lateral recess of a widely pneumatized sphenoid sinus is difficult to access with the use of(More)
Query by humming (QBH) means to search a piece of music by singing or humming. Given melodies hummed by the users, query by humming systems will return an ordered list of songs according to the similarity between hummings and target songs. Although there are many searching techniques for query by humming, our project is building a web-based query-by-humming(More)
Dynamic and elastic resource allocation to Virtual Network Functions (VNFs) in accordance with varying workloads is a must for realizing promised reductions in capital and operational expenses in Network Functions Virtualization (NFV). However, workload heterogeneity and complex relationships between resources allocated to a VNF and the resulting capacity(More)
OBJECTIVE To investigate the feasibility of image navigation technology in endoscopic skull base surgery. METHODS This study consisted of 75 patients who underwent the endoscopic operations with the help of the image navigation system by the same surgeon between March 2010 and March 2013. The time to prepair image navigation system, identifying anatomical(More)
In this paper, we make a case for using lightweight containers for fine-grained resource flexing for Virtualized Network Functions (VNFs) to meet the demands of varying workloads. We quantitatively compare the VNF performance and infrastructure resource usage of three instantiations (bare metal, virtual machine, and container) of three selected VNFs. The(More)
