Title:
NETWORK REPEATER
Document Type and Number:
Japanese Patent JP2013168832
Kind Code:
A
Abstract:

To provide a technology for specifying the generation source of a microburst, while reducing the processing load in a control unit as much as possible.

In order to classify the frames received by a reception port into three groups, a first reference value and a second reference value are defined in advance as the reference values related to the reception amount (reception band). The reception amount of frame is classified to a first nonspecific group (green region) when it does not exceed the first reference value, classified to a specific group (yellow region) when it does not exceed the second reference value, and classified to a second nonspecific group (red region) when it exceeds the second reference value. When a determination is made that a frame received by a reception port belongs to a specific group (yellow region), the content of a frame received by a reception port is copied and transmitted to a control unit for controlling a network repeater.
