Cluster-based server architectures combine good performance and low cost, and are commonly used for applications that generate heavy loads. Essentially, a cluster-based server consists of a front-end dispatcher and several back-end servers. The dispatcher receives incoming requests, and then assigns them to back-end servers, which are responsible for request processing. The many benefits of clu...

We consider a memoryless single station service system with servers S = {m1, . . . , mK}, and with job types C = {a, b, . . .}. Service is skill based, so that server mi can serve a subset of job types C(mi). Waiting jobs are served on a first come first served basis, while arriving jobs that find several idle servers are assigned to a feasible server randomly. We show that there exist assignme...

1. Motivation and description of demonstrated features Wireless mesh networks, comprised of nodes with multiple radio interfaces, are a promising technology for broadband residential Internet access or to provide connectivity for data transfer. In order to simplify network deployment, auto-configuration procedures that provide automatic network start-up, with minimum manual configuration of nod...

UNLABELLED Protein Structural Interactome map (PSIMAP) is a global interaction map that describes domain-domain and protein-protein interaction information for known Protein Data Bank structures. It calculates the Euclidean distance to determine interactions between possible pairs of structural domains in proteins. PSIbase is a database and file server for protein structural interaction informa...

The virtualization of Radio Access Networks (RANs) has been proposed as one of the important use cases of Network Function Virtualization (NFV). In Virtualized Radio Access Networks (VRANs), some functions from a Base Station (BS), such as those which make up the Base Band Unit (BBU), may be implemented in a shared infrastructure located at either a data center or distributed in network nodes. ...

We consider the problem of client assignment in a distributed system of content servers. We present a system called Webmapper for clustering IP addresses and assigning each cluster to an optimal content server. The system is passive in that the only information it uses comes from monitoring the TCP connections between the clients and the servers. It is also flexible in that it makes no a priori...

STRIDE is a software tool for secondary structure assignment from atomic resolution protein structures. It implements a knowledge-based algorithm that makes combined use of hydrogen bond energy and statistically derived backbone torsional angle information and is optimized to return resulting assignments in maximal agreement with crystallographers' designations. The STRIDE web server provides a...

One feature of Dynamic Host Configuration Protocol (DHCP) servers is the ability to assign static (fixed) IP Addresses for well-known clients in the Local Area Network (LAN) based on their Medium Access Control (MAC) addresses. This typically involves manual intervention by the network administrator to enter the correct MAC address and IP address information into the DHCP server configuration f...

In Distributed Virtual Environments (DVEs), where many simultaneous human users interact with each other in a shared, 3D virtual world, enhancing interactivity is of crucial importance, since the success of a DVE greatly depends on users’ perceptions. In general, enhancing interactivity for large-scale DVEs with thousands of geographically distributed users faces various challenges such as larg...

Maintaining the availability of critical servers and routers is an important concern for many organizations. At the lowest level, IP addresses represent the global namespace by which services are accessible on the Internet. We introduce Wackamole, a completely distributed software solution based on a provably correct algorithm that negotiates the assignment of IP addresses among the currently a...
