Abstract: PURPOSE: A packet forwarding control method for improving a TCP(Transmission Control Protocol) performance is provided to allow a user to use a smooth handoff method and a RED(Random Early Detection) buffer management method in a mobile IP(Internet Protocol) path optimization process. CONSTITUTION: A portable terminal forwards packets received from a terminal corresponding to a first FA(Foreign Agent) to a second FA via a buffer of a base station. The corresponding terminal does not catch an access point of the portable terminal. The base station manages the first FA. The base station determines a forwarding process or a discarding process for packets based on RED state information.

Abstract: PURPOSE: An NRZ(Non Return to Zero) signal clock extraction method capable of using a two mode fiber is provided to perform the 3R(Retiming, Reshaping, Re-amplification) with the extracted clock signal by having a similar function with the previous clock signal. CONSTITUTION: An optical signal is modulated into an NRZ-DPSK(Differential Phase Shift Keying) signal through a modulator.
