APPARATUS AND METHOD FOR LIMITING PACKET TRANSMISSION RATE IN COMMUNICATION SYSTEM
First Claim
Patent Images
1. A method for limiting a transmission rate of a packet in a communication system, the method comprising:
- creating an amount of tokens corresponding to a target transmission rate limit of the packet; and
at least one of dropping and providing the packet in consideration of an amount of the tokens created and a size of the packet.

Abstract
In a communication system, a token manager corresponding to a generated or arriving packet is determined, tokens corresponding to a target transmission rate limit are generated, and a corresponding packet is at least one of dropped and provided in consideration of the amount of the tokens created and the size of the generated packet. Through such a method, a packet transmission rate can be limited to the target transmission rate. In addition, when there is traffic of various service classes, service can be differentially provided according to the priorities of the service classes.

9. A method for packet scheduling in a communication system, the method comprising:
-
classifying one or more packets to be provided into classes; creating one or more tokens corresponding to a target transmission rate limit for each packet; and at least one of dropping and providing one or more packets of at least one class in consideration of threshold values set differently according to each of the classes when an amount of the tokens created is equal to or greater than a total size of the packets to be provided. - View Dependent Claims (10, 11, 12, 13, 14)
