Abstract
A network intermediate device and method are provided. The network intermediate device according to an exemplary embodiment of the present invention comprises a data transmitting/receiving part which receives frames which have header error check information, and a control part which controls the data transmitting/receiving part to start forwarding the frame before the entire frame is received by determining whether there are errors in the header using the header error check information. In this case, the frame may comprise a first field in which header error check flag information is recorded to notify whether to perform the forwarding after checking for errors in the header, and a second field in which the header error check information is recorded. If it is confirmed that the check and forward method is applied by the header error check flag information, the control part may verify the header error check information to determine whether errors occur in the header. Therefore, the relay of the frame can be stably performed within the minimum time.
