VNS is a multi-protocol switching architecture that provides COSsensitive packet switching, reduces the complexity of operating protocols like PPP and frame relay, provides logical networks and traffic segregation for Virtual Private Networks (VPNs), security and traffic engineering, enables efficient WAN broadcasting and multicasting, and reduces address space requirements. VNS reduces the num...

Practical experiments in a wide-area ATM network environment are essential to gain a better understanding of the factors affecting ATM performance. This article summarizes the main lessons learned through the authors' practical experiences with ATM and how these can be applied to performance tuning. In order to achieve maximum performance from an ATM WAN, factors ranging from the transport prot...

A simulation model is presented to analyze and evaluate the performance of VoIP based integrated wireless LAN/WAN with taking into account various voice encoding schemes. The network model was simulated using OPNET Modeler software. Different parameters that indicate the QoS like MOS, jitter, end to end delay, traffic send and traffic received are calculated and analyzed in Wireless LAN/WAN sce...

Many frameworks and packages exist for the development of robotic surgical systems. An important aspect of such packages involves the communication interfaces between various robotic devices. This paper discusses one such framework, the Surgical Assistant Workstation (SAW) developed at the Johns Hopkins University. SAW is a component-based framework, providing interfaces for the hardware and so...

Today, more and enterprises are embarking on a digital transformation where most of their applications hosted in the Cloud. As result, reliable Wide Area Network (WAN) has become primary need to interconnect distributed branch offices data centers that accommodate those applications. Software-Defined (SD-WAN) represents promising technology solution for next-generation enterprise networks, bein...

Integrating dedicated applications with a wireless LAN and WAN infrastructure, the COSMOS system provides "Construction Site Mobile Operations Support". In this paper, we focus on the approach taken in COSMOS for bandwidth management across the bottleneck satellite WAN link, particularly for supporting video conferencing between company headquarters and construction sites. We discuss the IETF Q...

We present ovulation that occurred after the administration of traditional Chinese herbal medicine for 3 months in a woman with premature ovarian failure (POF) and secondary amenorrhea for 8 years. Traditional Chinese medicine concentrated herbal extracts of cooked rehmannia, Chinese yam, wolfberry fruit, dogwood fruit, cyathula root, dodder seed, antler glue, tortoise-plastron glue, epimedium ...
