<p>Provided is a method of setting a QoS packet flow and processing a QoS packet for providing a QoS service. In the method of setting a QoS packet flow in the packet switching system, whether there are VOQs that are not pre-allocated is determined in response to a QoS packet flow setting request. If there are no VOQs that are not pre-allocated, it is determined whether there are VOQs that have not been used for a predetermined period. If there are VOQs that have not been used for the predetermined period, one of the VOQs is selected. Thereafter, an inactive state of a flow using the selected VOQ is indicated and QoS parameters set for the flow are released. Therefore, metro Ethernet services such as E-LINE and E-LAN can be provided in an Ethernet network and custom QoS services such as Diff Serv and ACL can be provided in an IP network. Also, limited resources can be efficiently used and thus costs can be reduced.</p> |
