PACKET PROCESSOR AND PACKET PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To reduce a memory capacity for packet accumulation to be provided within a packet selection device. SOLUTION: The processor is provided with the packet selection device 101 for determining whether a packet needs modifying, a write buffer 103 for accumulating the packet and a packet modifying device 111 for modifying the packet. The buffer 103 receives the packet from the device 101 to accumulate it and resends a packet write address to the device 101. The device 101 receives a packet write address from the buffer 103 and sends the packet and the packet write address to the device 111. The device 111 modifies the packet and writes the modified packet in the write buffer 103, in accordance with to the packet write address.
