Current means of providing loop-back recovery, which is widely used in SONET, relies on fiber-based recovery, where a fiber is used to back up another fiber. We present WDM-based loop-back recovery for optical networks where wavelengths are used to back up other wavelengths. We present two new algorithms for performing WDM-based loop-back over optical mesh networks. The first algorithm performs...

Most of the considerable work that has been done in the measurement of software complexity during thepast several years has addressed complexity measurement of source code or design languages. Here we describe techniques to measure the complexity of large (>lo0 000 source lines of code) systems during the software architecture phase, before major design decisions have been made. The techniques ...

The time transfer method of using passive listening and detection of SDH frame headers in fiberoptical networks has been presented earlier. Previous results, using commercialized equipment and commercial fiber-links, have shown that time transfer with a precision of the order of a few nanoseconds is possible over links with network distances exceeding 1100 km. The motivation of the work has bee...

The confinement of waves in a disordered medium—Anderson localization [1]—has been observed for electromagnetic [2, 3] and acoustic [4] waves in disordered dielectric structures, and for electron waves in condensed matter. Anderson localization arises as a result of the constructive interference between waves that follow time reversed paths as they loop back to a point as a result of scattering...

CDSS is a framework for the distribution of software installation media images and their contents over multiple file sharing protocols. The CDSS system provides a unique isolated server instance for every accessing user, even when another instance of that server is already running. CDSS uses the Linux host-based firewall system to transparently redirect inbound connections from each user to his...

Shared temporary storage space is often the constraining resource for clusters that serve as execution nodes in wide-area distributed systems. At least one large national-scale computing grid has reported a failure rate of as high as thirty percent of submitted jobs, often due to accidentally filled shared storage spaces. Previous systems have attacked this problem by adding space allocation to...

Due to exponential increase in communication speed when shifting from 4th Generation 4G 5G networks, there is a requirement redesign equipment support spectrum ranges 450 MHz 52.6 GHz, which makes them operate at very high speeds. In order maintain good performance while operating this bandwidth, millimeter waves (mmWaves) are used. As radius increases, the BER also increases linearly, limits r...

This paper presents the design and implementation of Modularly Optimized Round-robin ReadIntensive Storage (MORRIS), a file system which provides high throughput for read-intensive applications. NFSStripe, MORRIS’ primary component, is an NFS loopback server that achieves performance competitive with the traditional single-server model by distributing the task of data storage and retrieval over...

As the number of qubits in nascent quantum processing units increases, connectorized RF (radio frequency) analog circuits used first generation experiments become exceedingly complex. The physical size, cost and electrical failure rate all limiting factors extensibility control systems. We have developed a series compact mixing boards to address this challenge by integrating I/Q quadrature mixi...
