<p><P>PROBLEM TO BE SOLVED: To solve problems that emulation of an ATM network by a LAN network requires a line for synchronizing clock transmission and fluctuations in the LAN network cause no warrant of transmission along with a cell interval. <P>SOLUTION: An emulation synchronization system disclosed herein includes: a synchronizing information extract means that extracts a synchronizing clock from the ATM network; a transmission reception means that transmits/receives the synchronizing clock extracted by the synchronizing information extract means as synchronization information via the LAN network; and a synchronization information recovery means that recovers the synchronizing clock from the received synchronizing information and outputs the clock to the ATM network. Further, the system is provided with a data interval measurement means for measuring an input interval of transmission data received from the ATM network, and the transmission reception means transmits/receives the data interval information measured by the data interval measurement means and the transmission data are outputted to the ATM network at the data interval denoted by the received data interval information. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
