Abstract
A network relaying apparatus and a network relaying method for securing a high communication quality (QoS), a high reliability and security. A transfer engine stores the packets received through at least a network interface in a packet buffer, and the header information in a header RAM. A search engine searches for the transfer control information such as the destination information and the action information based on the header information, and writes them in the header RAM. The transfer engine prepares an output packet based on the information stored in the packet buffer and the header RAM, and outputs the output packet to the destination. A switch switches the output packet to the routing processor of the destination. Each header RAM is asynchronously accessible independently of the packet buffer and suppresses the competition for access between the transfer engine and the search engine.
