Web Security Gateway (WSG) is a new type of network security product that maintains the security of trusted networks. In this paper, a WSG model for evaluating WSG performance is presented. This paper advances discussion of previous studies on series services under multiple service windows. The proposed model consists of a two-stage queuing system. The first stage is a network layer simulation. The...
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...
In recent years, with the wisdom of the city promote and research in the field of geographic space unceasingly thoroughly, the mass spatial data storage management and multiple concurrent access has become the research hotspot in the field of geosciences. Traditional spatial data storage is based on relational database, modeling, index mechanism, cache management and task scheduling method to realize...
Compared with the traditional data mining system algorithms library, the introduction of Web Service technology into data mining system algorithm library realizes the separation of data, algorithm and interface. The loose and interconnected mode greatly reduces the complexity of the development for the algorithms library in data mining system and is convenient for the dynamic management of data mining...
