數據包過濾(Packet filtering)是一個用軟件或硬件設備對向網絡上傳或從網絡下載的數據流進行有選擇的控制過程。數據包過濾器通常是在將數據包從一個網站向另一個網絡傳送的過程中允許或阻止它們的通過(更為常見的是在從英特網向內部網絡傳輸數據時,或從內部網絡向英特網傳輸)。數據包過濾類防火墻對所有通過它進出的數據包進行檢查,并阻止那些不符合既定規則數據包的傳輸。

The goal of this thesis is the development of traffic engineering rules for cellular Packet radio networks based on GPRS and EDGE. They are based on traffic models for typical mobile applications. Load generators, representing these traffic models, are developed and integrated into a simulation environment with the prototypical implementation of the EGPRS protocols and models for the radio channel, which were also developed in the framework of this thesis. With this simulation tool a comprehensive performance evaluation is carried out that leads to the traffic engineering rules.

The outcome of the 3GPP SAE (system architecture evolution) technical study and specification work is a set of standards that specifies the evolution of the Packet core network for GSM/GPRS and WCDMA/HSPA to an all-IP architec- ture and enables a feature-rich ‘common Packet core’ for radio accesses devel- oped within 3GPP and also by other standardization fora.
