Abstract
A buffer device includes at least one internal switching unit and at least one basic buffer unit. The internal switching unit includes at least two inputs and at least two outputs. The internal switching unit and the basic buffer unit form a closed connection by alternating with each other via one input of the two inputs and one output of the two outputs. Another one of the at least two inputs of the internal switching unit receives a light wave. The internal switching unit outputs the light wave according to a first control signal. The basic buffer unit buffers the lightwave from the internal switching unit. At the same time, a network node and a scheduling method are also provided. A network node with the buffer device has a small scale and is easy to realize, while the data packet loss rate is decreased and the head of line blocking is avoided.
