On the Impact of Virtual Machine Overhead on Tcp Performance
نویسنده
چکیده
Virtual Machine (VM) based systems are widely used in the Internet and in corporate networks. In previous work we presented evidence that the virtualization overhead in a VM system perturbs TCP connections such that network performance deteriorates as compared to a non-VM system subject to the same user load. In this paper, we provide an explanation for these results. We show that that the underlying cause is due to VM overhead which induces ACK-compression resulting in highly bursty send behavior by a VM serving as a TCP end-point.

A hybrid model based on machine learning and genetic algorithm for detecting fraud in financial statements
Financial statement fraud has increasingly become a serious problem for business, government, and investors. In fact, this threatens the reliability of capital markets, corporate heads, and even the audit profession. Auditors in particular face their apparent inability to detect large-scale fraud, and there are various ways to identify this problem. In order to identify this problem, the majori...
متن کاملReducing deadline miss rate for grid workloads running in virtual machines : a deadline-aware and adaptive approach
This thesis explores three major areas of research; integration of virutalization into scientific grid infrastructures, evaluation of the virtualization overhead on HPC grid job’s performance, and optimization of job execution times to increase their throughput by reducing job deadline miss rate. Integration of the virtualization into the grid to deploy on-demand virtual machines for jobs in a ...
متن کاملCommunication-Aware Traffic Stream Optimization for Virtual Machine Placement in Cloud Datacenters with VL2 Topology
By pervasiveness of cloud computing, a colossal amount of applications from gigantic organizations increasingly tend to rely on cloud services. These demands caused a great number of applications in form of couple of virtual machines (VMs) requests to be executed on data centers’ servers. Some of applications are as big as not possible to be processed upon a single VM. Also, there exists severa...
متن کاملA Cross-Layer Optimization Semantic for Improving the Performance of TCP over CDMA Networks
In this paper a novel joint power and rate adaptation scheme for CDMA networks is proposed that integrate information from the TCP state machine. The impetus behind this cross layer optimization approach is twofold. Firstly, to minimize the Round Trip Time (RTT) variation, by tracking the varying transmission rate of TCP flows under a minimum power assignment. Secondly and most apropos, to adap...
