Provided is a method for providing quality of service (QoS) in a network including multiple nodes using an address system and an address resolution protocol (ARP). The method includes, at a current node, receiving a service request packet from a previous node using the address system and the ARP, checking whether the service request packet includes QoS request information, and determining whether the current node is capable of satisfying the QoS request. If the determination is affirmative, the current node transmits the service request packet with the QoS request information to a next node using the address system and the ARP. If the current node receives a reply packet from the next node, the current node determines whether the reply packet satisfies the QoS request. If the determination is affirmative, the reply packet including an address value of the current node is transmitted to the previous node.
