A single platform structure for a POS(Packet Over SDH(Synchronous Digital Hierarchy)) and EOS(Ethernet Over SDH), and a frame formatting method of the same are provided to be applied for a packet over WDM(Wavelength Division Multiplexing) technique and easily applied for a high capacity system environment. An SDH connecting and processing unit(100) selectively processes a POS or an EOS. A frame processing unit(200) selectively processes a frame of the POS or the EOS. A QoS control and packet I/O(Input/Output) processing unit(300) is connected with the frame processing unit(200) through an SPi(Synchronous Physical Interface). A frame switch unit(400) is connected with the QoS control and packet I/O processing unit(300). Each port of the frame switch unit(400) is connected with the QoS control and packet I/O processing unit(300) through eight ports, and connected with a backplane through sixteen ports. |
