Whitepaper: The Location-Based Services in Local Area Using Wireless LAN

by Electronics and Telecommunications Research InstituteJan 01, 2008

This paper published by Electronics and Telecommunications Research Institute describes that location-based services using location information of mobile devices in wireless LAN are applicable to in-door, hotspot, and downtown areas. The gathering module on signal strength of Access Points (AP), a Positing Determination Server (PDS), and LBS applications in WLAN are presented in this paper. Moreover, the server provides the applications with GIS maps and location of the mobile device in the form


Whitepaper: End-to-End Flow Monitoring With IPFIX

by Electronics and Telecommunications Research InstituteJan 01, 2008

End-to-End (E2E) flow monitoring is helpful for observing performance of networks such as throughput, loss rate, and jitter. However, in a large-scale network, the end-host approach for performance measurement may not be easily implemented because of expensive costs and high administrative overheads. This white paper presents a new E2E flow monitoring method based on IP Flow Information eXport (IPFIX) that could provide QoS metrics such as throughput, retransmission rate, delay and jitter for
