PACKET SENDING DEVICE AND PACKET SENDING PROCESSING METHOD

摘要

PURPOSE: A packet sending device and a packet sending processing method are provided to perform priority control with excellent transmission quality while assuring a contracted bandwidth. CONSTITUTION: An identifier assigning section(214) assigns one of the first to third identifiers to a received packet after receiving the packet transferred over each input link. The first identifier indicates that the packet has a relatively high priority and does not exceed an assured bandwidth which is determined with a predetermined method. The second identifier indicates that the packet has relatively low priority and does not exceed the assured bandwidth. The third identifier at least indicates that the packet exceeds the assured bandwidth. A packet transmitting section(28) performs a necessary process on the packet assigned with one of the first to third identifiers by the identifier assigning section(214), and outputs the processed packet to an output link.
