PURPOSE: An apparatus and a method for allocating resources according to path colors for a differentiated service is provided so that an ISP(Internet Service Provider) can provide a differentiated service to Internet users. CONSTITUTION: A bandwidth broker(300) comprises a user interface part(310), a determination part(320), a GUI part(330), a router interface part(340), a database(350), a routing protocol part(360), and an SNMP management part(370). The bandwidth broker(300) receives user requirements from a user terminal(380) through the user interface part(310), and delivers a resource allocation result to the user terminal(380) through the user interface part(310). The determination part(320) checks the user's contract observance items, based on the user requirements transferred from the user interface part(310), and determines whether the user's request is acceptable. In this case, the bandwidth broker(300) executes acceptance control, based on a path color. The database(350) stores user requirements, router setup conditions, network resource usage policy, router information, network configuration information, etc. The routing protocol part(360) collects network configuration information, stores it in the database(350), and uses stored information in setting up each path between edge routers. The SNMP management part(370) collects information from routers through an SNMP and stores it in the database(350).
