Abstract

A transmitter, a communication system, and a communication method capable of realizing communication of more than a set bandwidth with respect to a packet communication with a bandwidth guarantee set therefore by using a set bandwidth as the minimum guaranteed bandwidth, wherein when a transmitter transmits packet data, it decides whether or not packet communication guarantees a bandwidth based on a guaranteed bandwidth set in advance, and adds a first identifier to the packet data when guaranteeing bandwidth, and adds a second identifier when not guaranteeing the bandwidth.

Claims

1-6. -6. (canceled)

8. A transmitter for transferring packet data from a transmitter side to a receiver side via a network, comprising:

identifier adding means for deciding whether or not the packet data is transmitted exceeding a guaranteed bandwidth based on a preset guaranteed bandwidth set in advance with respect to the transfer of the packet data and adding a first identifier to the packet data when the packet data is transmitted without exceeding the guaranteed bandwidth, and adding a second identifier to the packet data when the packet data is transmitted exceeding the guaranteed bandwidth,

transmitting means for transmitting the packet data to which the identifier has been added to the network,

registering means for registering identifiers corresponding to packet data to be transferred without exceeding the preset guaranteed bandwidth and guaranteed widths. and

receiving means for receiving packet data transferred via the network.

7. A transmitter as set forth in claim 8 wherein the identifier adding means decides whether or not the packet data received by the receiving means has been transmitted exceeding the preset guaranteed bandwidth, and, in accordance with the decision, adding one of a first identifier and second identifier to the packet data.
