NWS 1: Network traffic monitoring, analysis and anomaly detection

Modern computer networks are increasingly pervasive, complex, and ever-evolving due to factors like enormous growth in the number of network users, continuous appearance of network applications, increasing amount of data transferred, and diversity of user behaviors. Understanding and measuring such a network is a difficult yet vital task for network management and diagnosis. Network traffic monitoring, analysis, and anomaly detection provide useful tools for understanding network behavior and determining network performance and reliability so as to effectively and promptly troubleshoot and resolve various issues in practice.

NWS 2: A Generic NFC-enabled Measurement System for Remote Monitoring and Control of Client-side Equipment

NFC technology can be integrated into existing systems to simplify and speed up the process of monitoring and control of these systems. In this paper we address a problem pertaining to the complexity of the monitoring and control of sensor or measurement equipment. Manual monitoring of measurement systems can be a tedious endeavor, especially in systems where the measurements are numerous and at regular intervals. A possible solution to the tediousness of manual monitoring is to link up measurement systems to a computer using a suitable communication protocol, but this becomes a problem if the monitoring needs to be done remotely or the measurement device needs to be mobile. We propose using NFC technology to facilitate the process of data acquisition from a measurement or sensor device. An existing measurement device can be fitted with an NFC interface to enable easy access to measurement data by simply touching the device with an NFC reader. By using an NFC-enabled mobile phone as a reader, the GPRS capabilities of the phone can be implemented to enable the transmission of acquired data to a remote location. The process is activated by simply bringing an NFC-enabled mobile phone into close proximity of an NFC-enabled measurement device. From a remote location, data from these devices can be processed and control commands can be sent to the devices, using an NFC-enabled mobile phone as an intermediary device. Applying NFC to measurement devices can save time and effort, and no specialized skills are needed by a person initiating the acquisition of data, as a simple "touch' is all that is required.

NWS 3: A Speech Remote Control System Realization Based on Computer Telecommunication Integration

Speech control is a hotspot in intelligent control technology. Automatic speech control means that machines can recognize the context of human's voice, and carry on the human's mind based on the recognition results. A speech remote control system is been realized based on computer telecommunication integration and Web Service in this project. And the system structure, technical implement and main function modules have been introduced in detail.

NWS 4: RITAS: Services for Randomized Intrusion Tolerance

Randomized agreement protocols have been around for more than two decades. Often assumed to be inefficient due to their high expected communication and computation complexities, they have remained overlooked by the community-at-large as a valid solution for the deployment of fault-tolerant distributed systems. This paper aims to demonstrate that randomization can be a very competitive approach even in hostile environments where arbitrary faults can occur. A stack of randomized intrusion-tolerant protocols is described and its performance evaluated under several settings in both local-area-network (LAN) and wide-area-network environments. The stack provides a set of relevant services ranging from basic communication primitives up to atomic broadcast. The experimental evaluation shows that the protocols are efficient, especially in LAN environments where no performance reduction is observed under certain Byzantine faults
