Network Functions (NFs) are deployed in networks for a variety of purposes, e.g. monitoring, security, or performance optimization. During packet processing, NF maintains the states of processed packets and/or manipulates packets based on these states. Some of these states are per-flow states while others are multi-flow states. With the emerging of network function virtualization (NFV), it is common...
With the high-speed development of the network, the web platform has been wildly applied to various kinds of industries. The paper analyses MVC pattern framework, which can truly achieve a complete separation of the view, controller and model, implement the separation of business logic and presentation layer, and improve the development efficiency and software reusability. The research is designed...
Location-Based Service (LBS) has become pervasive, riding along the trend of mobile application proliferation. Given its high utility value, LBS, however, present serious privacy concerns for cautious users. In this paper, we investigate privacy preserving for location-based information survey application, which calculates the geographic distribution of user's information. The design objective is...
Along with collaborative development in Java development, collaborative remote debug without sharing all the source code becomes a new requirement. Current approach wastes too much time in network communication and is also constrained by network port. This paper proposes a system and method to support multiple-party collaborative remote debug without sharing all the source code and without port constraint...
Web map service is a new map service mode actualized by the use of internet technology, computer technology and GIS technology. This article applies Web map service to the release of land use information, and tries to use Google Maps API and XML to build a network release system of regional land use information. The system integrates Google Maps data and user data effectively, carries out the display...
On the basis of the estimation process of crop output potential and taking county as a unit, the paper sorted out attribute data of meteorology, soil, and society production, and spatial data in 30 counties of Henan Province, built the integrated space-attribute database, designed system structure by adopting C/S and B/S, and developed GIS-based estimation system about wheat output potential in county...
The throughput of Peer-to-Peer (P2P) Video-on-Demand (VoD) systems is typically capped by the users' aggregate upload bandwidth [1]. The drastic increase in the popularity of VoD and the demand of higher quality content has thus placed substantial burden on the content servers. We investigate a novel P2P VoD architecture that leverages idle Internet resources, which we call helpers, to provide a scalable...
Recently in-depth analysis of network security vulnerability must consider attacker exploits not just in isolation, but also in combination. The general approach to this problem is to compute attack graphs using a variety of graph-based algorithms. However, such methods generally suffer the exponential state space problem. Therefore, this paper brings forward two conceptions of vulnerability correlation...
IP address shortage over IPv4 is a big problem now, therefore the more massive deployment of NAT equipments is coming. One of the urgent problems for P2P is that how can each peer behind NAT find others and can establish direct connection to others. This paper discusses a TCP-based traversal model on the foundation of existing traversal methods having been analyzed, designs and presents the details...
The turbo-generator unit is very important equipments for electric power production, which has a high rate of fault and causes a lot of harm because of the structural complexity and the special circumstance. With the increasing of the capacity of the unit, the condition monitoring and fault diagnosis plays an important role to ensure safe operation and guarantee the efficiency. Therefore, the real-time...
