Design of a Lightweight Packet Classifier and Its Application in LBS
摘要
Abstract
A lightweight implementation of finite-state general-purpose datagram matehers with linear matching cost is proposed. The given matcher provides plug-in-and-play function by exposing software object slots, as a result message classifying and data process are isolated and software scalability is ensured. After that, through aggregation technology, a multi-classifier is presented to automatically recognize kinds of message types and effectively help extract valid data. In the end, the C ++ programming language is used to implement the design, and it is used in LBS system for processing NMEA0183 datagram from GPS receivers.关键词
