After studying the current principle andarchitecture of antivirus gateway for Web security detection, we found that the conventional virus scan is based on filescanning, which takes significant processing time. Whenscanning big size files, it may often cause disconnection of filetransferring with a time-out error message prompted out. Tosolve the problem of slow file virus scan, we propose a newmethod...
We present a cloud resources integrated provisioning architecture utilizing coordinated virtualization of distributed datacenters and operator's multi-domain software define optical network. The overall feasibility and efficiency of two proposed virtual network composition schemes are investigated on our testbed.
Cloud computing provide scalability and high availability for web applications using such techniques as distributed caching and clustering. As one database offloading strategy, elastic caching platforms (ECPs) are introduced to speed up the performance or handle application state management with fault tolerance. Several cache strtegies for ECPs have been proposed, say replicated strategy, partitioned...
Selective regression testing involves retesting of software systems with a subset of the test suites to verify that modifications have not adversely impacted existing functions. Although this problem has been heavily researched, it has never been discussed in the context of SaaS (Software as a service). This paper presents the specific requirements, challenges and benefits in delivering regression...
With the rapid growth of both information and users, how to effectively improve the quality of network service becomes an urgent problem to be addressed. Load balancing is to overcome this problem in an effective way. At present it is mainly achieved by the load-balancing hardware and software, but there are also many problems, such as unscientific and inaccurate algorithm, imperfect and impractical...
