Characterizing datasets like this can be helpful to others. The use of looking glass servers gives very up-to-date sets of links. This paper demonstrates that it also provides a large data set, whereas prior work appears to have only used LG servers to verify data collected from other sources. The study highlights the utility of the looking glass servers for collecting this additional informati...

Policy iteration techniques for multiple-server dispatching rely on the computation of value functions. In this context, we consider continuous-space M/G/1-FCFS queue endowed with an arbitrarily designed cost function waiting times incoming jobs. The associated relative is a solution Poisson’s equation Markov chains, which in work solve Laplace transform domain by considering ancillary, underly...

This paper analyzes an M/M/2 queueing system with two heterogeneous servers. Both servers goes on vacation when there is no customers waiting for service after this server 1 is always available but the other goes on vacation whenever server 2 is idle. The vacationing server however, returns to serve at a low rate as an arrival finds the other server busy. The system is analyzed in the steady st...

the probability of losing a customer in m/g/n/0 and gi/m/n/0 loss queuing systems withheterogeneous servers is minimized. the first system uses a queue discipline in which a customer who arriveswhen there are free servers chooses any one of them with equal probability, but is lost otherwise. providedthat the sum of the servers rates are fixed, loss probability in this system attains minimum val...

The increasing need for rapid introduction of new services and highly customised service offerings poses additional management challenges for today's networks. In this paper we propose a flexible distributed management system based on role driven policies and active layer networking that addresses these demands. Management information is distributed via a hierarchy of Information Servers which ...

There is an increasing demand for IT resources in growing business enterprises. Data center virtualization helps to meet this by driving higher server utilization and utilizing un-used CPU cycles without causes much increase new servers. Reduction infrastructure complexities, Optimization of cost system management, power cooling are some the additional benefits virtualization. Virtualization al...
