A QoS providing method using an address system and an ARP(Address Resolution Protocol) are provided to simply reserve network resources required for QoS even without using a complicate protocol such as an RSVP(Resource ReserVation Protocol). When the current node receives a service request packet by using an address system and an ARP from a previous node, the current node checks QoS request information included in the request packet, and determines whether the requested QoS can be satisfied(S301,S303,S305). When the requested QoS cannot be satisfied, the current node includes the QoS request information in the service request packet and transmits it to the next node by using the address system and the ARP(S307). When a response packet with respect to the request packet is received from the next node, the current node determines whether the response packet satisfies the requested QoS(S309,S311). When the requested QoS is satisfied, the current node includes an address value of the current node satisfying the requested QoS in a response packet and transfers it to the previous node(S313).
