Abstract
In a transmission apparatus, a shaping circuit shapes a packet output from a switch in a band of predetermined granularity. A packet generation circuit generates a band correction packet in a band smaller than the band of the predetermined granularity of the shaping circuit and inputs the band correction packet to the shaping circuit.
Claims7
A transmission apparatus which transmits user packets, comprising:
- a shaping circuit configured to shape traffic of packets within a limited shaping rate that is specified from among discrete values with a predetermined granularity;
- a packet generation circuit configured to generate band correction packets whose rate is smaller than the predetermined granularity, and enter the generated band correction packets to the shaping circuit, as part the traffic of packets to be shaped;
- and
- a queue circuit, as part of the shaping circuit, configured to store the packets to be shaped which include both the user packets to be transmitted and the band correction packets entered from the packet generation circuit.
