Abstract
There are provided a QoS Ethernet switch and a flow QoS processing method using the same. More particularly, there is provided a technology that can easily ensure IP service quality at low cost by introducing IP flow QoS function to an Ethernet switch.
Claims5
A flow QoS Ethernet switch comprising:
- a packet switch performing Ethernet layer switching;
- and
- a plurality of flow QoS line cards located at an input terminal or an output terminal of the packet switch and providing QoS for IP flows passing through the packet switch.
A flow QoS processing method using an Ethernet switch supporting IP flow QoS, the method comprising:
- determining whether packets input through an external interface or a packet switch correspond to traffic subject to flow QoS;
- determining whether the input packets are IP packets when the input packets correspond to traffic subject to flow QoS;
- accessing flow QoS profile information about the IP packets subject to flow QoS;
- and
- applying flow QoS to the IP packets subject to flow QoS according to the flow QoS profile information.
