This paper provides a way of HTTP authentication On Alcatel OmniSwitch 9700. Authenticated VLANs control user access to network resources based on VLAN assignment and user authentication. The user can be authenticated through the switch via any standard Web browser software. Web browser client displays the username and password prompts. Then a way for HTML forms can be given to pass HTTP authen...

We consider the server load balancing problem which is originated from optimal web hosting in cloud computing. We have developed VNS-based heuristic to tackle this problem. In order to improve the efficiency of the algorithm, we apply new exponential neighborhood based on the assignment problem. Computational experiments on real world and randomly generated test instances indicate the efficienc...

We study the dynamic assignment of flexible servers to stations in the presence of setup costs that are incurred when servers move between stations. We focus on tandem lines with two stations and two servers with the goal of maximizing the long-run average profit. We investigate how the optimal server assignment policy for such systems depends on the magnitude of the setup costs, as well as on ...

ARTICLE HISTORY: Received 24 October 2015 Revised 7 December 2015 Accepted 9 December 2015 This paper deals with the problem of user-server assignment in online social network systems. Online social network applications such as Facebook, Twitter, or Instagram are built on an infrastructure of servers that enables them to communicate with each other. A key factor that determines the facility of ...

a two server queueing system with single and batch service is considered in this paper. the arrival process is assumed to be poisson and the service rate follows an exponential distribution. server-i serves the customers in both single and batch service, while server-ii serves the customers in batch service only. the laplace transform of the transient and steady state behavior of the model is c...

in this paper, we present a novel algorithm for vanet using cloud computing. we accomplish processing, routing and traffic control in a centralized and parallel way by adding one or more server to the network. each car or node is considered a client, in such a manner that routing, traffic control, getting information from client and data processing and storing are performed by one or more serve...

We propose a multimedia server allocation problem in the 3G wireless networks as a generalized assignment problem (GAP) with an objective of minimizing the total multimedia applications access cost. Because the GAP is a well known NP hard problem, we use the Lagrangian relaxation (LR) heuristic to compute a lower bound on the total multimedia applications access cost. For small size problems, w...

Advances in storage technologies are making it feasible to design video servers that are capable of supporting continuous, real-time delivery of multiple video streams simultaneously. One of the major design considerations for a large-scale video server is scalability, to admit and service thousands of subscriber requests simultaneously. In this paper, we deene and formulate various policies th...

Distributed linearly separable computation, where a user asks some distributed servers to compute function, was recently formulated by the same authors and aims alleviate bottlenecks of stragglers communication cost in computation. The data center assigns subset input datasets each server an uncoded manner, computes coded packets on assigned datasets, which are then sent user. should recover ta...

A new approach to the deployment of public key infrastructure is presented, based on a separation between the issuing of certificates and the usage of certificates. Certificates are signed assertions by the issuer about the subject of the certificate (holder of corresponding secret key), not necessarily identifying the subject. Typical use of certificate is for access control decisions, to dete...
