The era of cloud based multimedia applications has lead to a huge increase in the no. of requests on cloud. The increased no. of requests on cloud leads to an increased workload, making workload balancing an important QoS Parameter. Workload Balancing also leads to a judicious use of resources like electricity etc. and thus promotes the concept of Green IT. The paper presents a new Load Balanced Resource...
In a typical cloud based data centre, several physical machines (PM) host dozens of virtual machines (VM), which run various applications and services. VM load varies according to the different type of users' applications and traffic, and sometime this traffic may overwhelm VM's resources. Physical machines that host many VMs have limited capacity and if they are overloaded their performance might...
Distributed Denial of Service (DoS) attacks is one of the major threats and among the hardest security problems in the Internet world. In this paper, we study the impact of a UDP flood attack on TCP throughputs, round-trip time, and CPU utilization on the latest version of Windows and Linux platforms, namely, Windows Server 2012 and Linux Ubuntu 13. This paper also evaluates several defense mechanisms...
Data centers are becoming a significant energy consumer. Server workload, cooling, and supporting infrastructure represents large loads for the grid. This paper intends to present a comprehensive literature review that account for generation, loads, storage, and topology of data centers. It is shown that green data centers are emerging which incorporate renewable energy sources to cap their carbon...
Cloud computing has officially entered the commercial application stage, which puts forward higher requirements on network load balancing. Leveraging effective load distribution and traffic scheduling algorithm to reasonably allocate the request data between every processing nods to achieve optimal processing capacity of the system is one of the effective ways to improve the utilization of network...
Social networks and other clouding applications should require a fast response from datacenter's infrastructure. One of the techniques that has been widely used for achieving such requirements is the employment of In-Memory Key-Value Storage (IMKVS) as caching mechanisms in order to improve overall user experience. Memcached and Redis are applications that use IMKVS approach. Commonly IMKVS clients...
Cloud technologies have become an integral component in all aspects of the internet operation. In order to optimize the access to their services and infrastructures the cloud providers have implemented various techniques to load balance the globally spread datacenters and reduce the services latency. This paper analyses the technologies that are used in the cloud today and their applicability to local...
“The University Consortium for e-Learning, Shikoku Center” is a parent organization of Cooperative University e-Learning Project for the Shikoku Area. The organization consists of five national universities in Shikoku area of Japan. Kagawa University takes the initiative of this project. The aim of this organization is to improve the educational quality in the five universities using e-Learning technology...
This paper studies the load balancing problem in distributed systems designed for massively multiplayer online role-playing games (MMORPGs). More concretely, we consider a distributed system of master-worker type in which each worker is associated with a particular region in the game field, and propose a scheme to balance the load of workers as much as possible. The basic idea of the proposed scheme...
In a distributed system, there is always a question of how to distribute any data across the constituent systems. Consistent hashing is often used to get this system mapping based on a hash function and the data. Hence it becomes solely responsible for the distribution of the workload across the different systems. The default consistent hashing partitioning scheme doesn't factor in the load distribution...
With rapid increasing demand of cloud computing technology, energy efficiency has become highly important in cloud computing infrastructures. Cloud computing concept offers low cost and high level of availability. However, it still has some challenging problems, such as resource management and power consumption. In this concept, reducing energy consumption and maximize resource utilization, became...
Resource allocation and management in Cloud Computing is a very complex task. This is mainly due to the scale of the cloud and the number of services deployed in it. Since cloud users and service providers are given access to supercomputerlevel resources, their effect over the cloud's overall performance is greater than ever. This raises multiple research questions related to the management and performance...
Machine Type Communications (MTC) has been paid much attention as a new communication paradigm to increase mobile network traffic. Most of MTC terminals are time-driven, that is, they send and receive data periodically. Therefore, network access requests on mobile core networks are concentrated at a specific timing, which results in instantaneous increase in network load. Considering the fact that...
The Flemish project Linear was a large scale residential demand response pilot that aims to validate innovative smart grid technology building on the rollout of information and communication technologies in the power grid. For this pilot a scalable, reliable and interoperable ICT infrastructure was set up, interconnecting 240 residential power grid customers with the backend systems of energy service...
These days our networks have to handle large amount of traffic, serve thousands of clients. It is very difficult for a single server to handle such huge load. The solution is to use multiple servers with load balancer acting as a front end. The clients will send the requests to the load balancer. The load balancer will forward the client requests to different servers depending upon load balancing...
To facilitate researchers and scientists an ePPMS (electronic Project proposal Management system) is implemented using spring and Hibernate and designed using HTML5 and CSS3.PostgreSQL database was used as back end. The developed system has overcome the time consuming process of research proposal submission, scrutiny,review, obtaining required reports and certificates, monitoring etc. The Model-View-Controller...
Demand response offers financial incentives for consumers who are willing to relocate some or all of their electricity demand during peak periods. In price based demand response programs, utility companies can use energy pricing as an effective control signal to reschedule electricity demand from peak hours to off-peak periods. A real-time (RT) residential time-of-use pricing system with closed-loop...
With the continuous development of cloud computing, bigger and bigger data processing run in the cloud computing environment. In generally, large companies or organizations have the demand of big data processing. However, these companies or organizations do not want to expose their business processes and data to third parties (Amazon, Google, etc.). The private cloud could meet their needs. In private...
Cloud computing is a new platform in the field of information technology which faces the problem of load balancing as one among the other problems such as security and privacy. Efficient load balancing guarantees efficient utilization of resources by allocating the resources to users on demand. This paper presents a survey on various load balancing techniques and various task scheduling algorithms...
The cloud computing applications has key building blocks in distributed file system based on Map Reduced programming. Nodes serve computing features and storage. A file is divided into chunks and that can be allocated in the nodes. As files can be created, moved, updated and deleted. This leads to load imbalance in the file system. It is necessary to distribute the file chunks uniformly across the...
