Patent ID: 7633883

Claim:
A network traffic controlling method being progressed by a switching control module individually mounted to each switches connected to other switches through ports, the method comprising the steps of: building a neighborship according to frames transmitted from certain neighbor switches among the other switches; synchronizing switch state information, wherein switch state information retained by the other switches is real-time exchanged whenever the information is changed; updating a switching table according to the synchronized switch state information; and processing a data frame, wherein after a data frame is received, the received data frame is switched or flooded to a port connecting to a destination depending on the frame types, with reference to the switching table, wherein the step of building the neighborship comprises sub-steps of: determining whether a hello frame is received from the neighbor switches while sending a self hello frame to all activated ports; when the hello frame is received from the neighbor switches, determining whether a self switch ID is included in the neighbor switch list of the received hello frame; and when the self switch ID is included in the neighbor switch list of the hello frame, recording information of a neighbor switch having transmitted the hello frame to a neighbor switch D/B.
