Abstract: Disclosed herein is an apparatus and method for scheduling packets using a credit based round robin in a high-speed communication network in which packets are transmitted to and received from a plurality of connections having respective speeds of service. The scheduling apparatus includes a packet pool 33 for storing input packets 31; a token queue 35 for storing tokens 36 each having a connection identifier (ID) of an input packet 31 stored in said packet pool 33, the round number (RN) of the connection, and a credit value (CV) for service; and a connection management unit 34 for transmitting the input packets 31 to said packet pool 33, reading the packets stored in said packet pool 33, generating the tokens 36 each having a connection identifier (ID) of an input packet 31 stored in said packet pool 33, the round number (RN) of the connection, and a credit value (CV) for service and transmitting them to said token queue 35, and servicing the packets of said packet pool designated by the token 36 stored in said token queue 35.
