ABSTRACT:
A network connection device with improved processing speed for exchanging a frame including content addressable memories (CAMs), each having predetermined data stored in each of a plurality of entries in advance, for checking whether or not the predetermined data of each entry conforms to data of the frame transmitted from a sender network. The device also includes a table memory, provided to correspond to each entry of the CAM, for storing data of the other CAM to be searched next or an address of a destination sender network. The device further includes a data continuous search processing circuit for obtaining the address of the destination network of the frame from the sender network by use of data and the address stored in the table memory and a checking means when the CAM checks that the predetermined data conforms to data from the sender network, for setting the address of the frame from the sender network having the address of the frame from the sender network obtained, and for transmitting the frame having the address of the destination network set to the sender network. The checking means is continuously accessed based on data sent from the storing means, so that the address of the network can be obtained. The device achieves improved processing speed by use of the continuous search.
