Abstract

A circuit emulation method with garbage removal is used to convert a circuit-switched network for packet-switched transmissions while reusing as much of the existing circuit-switched infrastructure as possible. The garbage removal function removes unnecessary information from a packet before it can be transported, which increases the transport efficiency and decreases the transport delay.
