Server consolidation is the hosting of multiple tenantson a server machine. Given a sequence of data analyticstenant loads defined by the amount of resources that thetenants require and a service-level agreement (SLA) between thecustomer and the cloud service provider, significant cost savingscan be achieved by consolidating multiple tenants. Since servermachines can fail causing their tenants to...
Cloud computing is now trending and more popular in these days for the computation and adopted by many companies like google, amazon, Microsoft etc., As the cloud size increases with increase in number of data center power consumption over a data center increases. As number of request over the data center increase with increase in load and power consumption of the data center. So the requests need...
Rendezvous is a necessary operation for cognitive users to establish communication links in cognitive radio networks (CRNs). To guarantee the rendezvous in finite time, all existing rendezvous algorithms generate CH (channel-hopping) sequences using the whole channel set and attempt rendezvous on each of the channels (i.e., both available channels and unavailable channels). In practice, the available...
The scale and complexity of online applications and e-business infrastructures has led service providers to rely on the capabilities of large-scale hosting platforms, i.e., data centers. Dynamic resource allocation (DRA) algorithms have been shown to allow server resource allocation to be matched with application workload, which can improve server resource utilisation and drive down costs for service...
The notion of probabilistic network has been used to characterize the unpredictable environment in wireless communication networks or other unstable networks. In this paper, we are interested in the problem of placing servers in probabilistic networks subject to budget constraint, so as to maximize the expected number of servable clients that can successfully connect to a server. We study this problem...
The broadcast problem including the plan design is considered. The data are inserted and numbered into customized size relations at a predefined order. The server ability to create a full, regular Broadcast Plan (RBP) with single and multiple channels, after some data transformations, is examined. The Basic Regular Algorithm (BRA) prepares an RBP and enables users to catch their items avoiding wasting...
In a P2P-based media distribution network (PMDN), content migration is one of the key problems that affect the overall performance of a system. In the system hierarchy, the content migration problem consists of two levels of migration: provider-level migration and user-level migration. In this paper, we focus on the former, provider-level migration, where the goal is to reduce data migration cost...
The skyline operator has received considerable attention from the database community, due to its importance in many applications including multi-criteria decision making, preference answering, and so forth. In many applications where uncertain data are inherently exist, i.e., data collected from different sources in distributed locations are usually with imprecise measurements, and thus exhibit kind...
The network topology discovery is the basis of network management. A hierarchical design model which includes access layer, distribution layer and core layer is widely used in a construction of a switched LAN. ??Layer 3 switching?? and VLAN is used in equipments from different vendors. This paper proposes an algorithm of physical topology discovery of heterogeneous IP networks with VLAN which is designed...
Distributed Virtual Environment (DVE) systems have become more and more important both in academic communities and the industries. To guarantee the load constrain, the physical world integrity and the virtual world integrity, the virtual environment should be divided into several parts and mapped to multiple servers, which are located in geographically different places. Many centralized algorithms...
This paper designs a framework for the new media services platform in China. By analyzing the functions of key modules, we establish an ontology semantic framework for description and organizing the heterogeneous new media resources of data, data flows, streams, and rules of the services detected from the user interactions context and node trust evaluation. Also we establish an optimal model for RSS...
With the increasing augment of visits and data exchange, improving the utilization ratio of servers inevitably become a block that in front of all system managers. Although the technology of load balancing algorithm find the way to solve this problem, traditional method contains several serious shortages, such as low utilization ratio, long response latency, etc. In this article, a new algorithm is...
