Guaranteeing quality of service (QoS) using bandwidth reservation in switch
First Claim
1. A method of guaranteeing Quality Of Service (QoS) using bandwidth reservation in a switch, the method comprising:
- establishing a MAC table including MAC addresses of terminals connected to each port of the switch and an identifier indicating whether or not the corresponding terminal is a Voice over Internet Protocol (VoIP) terminal;
calculating a VoIP bandwidth necessary for each port based on information of the MAC table, calculating a ratio of an entire bandwidth to a bandwidth equal to the entire bandwidth minus the VoIP bandwidth, and setting the ratio as a port ratio of the switch;
determining whether or not a corresponding packet is a VoIP packet by filtering the MAC address of the corresponding packet upon an arbitrary packet being input into the switch; and
passing the corresponding packet upon a determination that the corresponding packet is a VoIP packet, and passing the corresponding packet only when the bandwidth of the corresponding packet is within a permissible limit of the set port ratio by performing port ratio control upon a determination that the corresponding packet is not a VoIP packet.

Abstract
A method for guaranteeing Quality of Service (QoS) using bandwidth reservation in a switch includes: establishing a MAC table including MAC addresses of terminals connected to each port of the switch and an identifier indicating whether or not the corresponding terminal is a VoIP terminal; calculating a VoIP bandwidth necessary for each port based on information of the MAC table, calculating a ratio of an entire bandwidth to a bandwidth equal to the entire bandwidth minus the VoIP bandwidth, and setting the ratio as a port ratio of the switch; determining whether or not the corresponding packet is a VoIP packet by filtering the MAC address of the corresponding packet upon an arbitrary packet of the switch being input; and passing the corresponding packet upon a determination that the corresponding packet is a VoIP packet, and passing the corresponding packet only when the bandwidth of the corresponding packet is within a permissible limit of the set port ratio by performing port ratio control upon a determination that the corresponding packet is not a VoIP packet.

7. A communication system comprising:
-
a switching system adapted to establish a MAC table including MAC addresses of terminals connected to each port of a switch and an identifier indicating whether or not a corresponding terminal is a VoIP terminal, and adapted to process the corresponding packet by assigning a bandwidth reserved in the switch upon the corresponding packet being determined to be a VoIP packet on the basis of the MAC table by filtering an originating MAC address of the corresponding packet upon an arbitrary packet being input; and at least one VoIP terminal, the at least one VoIP terminal being assigned an IP address from the switching system by being connected to the switch of the switching system, and being guaranteed a Quality of Service (QoS) set using the bandwidth reserved in the switch of the switching system via the MAC address of the VoIP terminal registered in the MAC table of the switching system. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method of guaranteeing a Quality of Service (QoS) using bandwidth reservation in a switch, the method comprising:
-
establishing a MAC table including MAC addresses of terminals connected to each port of the switch and an identifier indicating whether or not a corresponding terminal is a specific terminal; calculating a reservation bandwidth necessary in each port based on information of the MAC table, calculating a ratio of an entire bandwidth to a bandwidth equal to the entire bandwidth minus the reservation bandwidth, and setting the ratio as a port ratio of the switch; determining whether or not the corresponding packet is a packet of the specific terminal by filtering a MAC address of the corresponding packet upon an arbitrary packet being inputted to the switch; and passing the corresponding packet upon a determination that the corresponding packet is the packet of the specific terminal, and passing the corresponding packet only when a bandwidth of the corresponding packet is within a permissible limit of the set port ratio by performing port ratio control upon a determination that the corresponding packet is not the packet of the specific terminal.

15. A communication system comprising:
-
a switching system adapted to establish a MAC table including MAC addresses of terminals connected to each port of a switch and an identifier indicating whether or not the corresponding terminal is a specific terminal, and adapted to process a corresponding packet when an arbitrary packet is inputted by assigning the bandwidth reserved in the switch when the corresponding packet is determined to be a packet of the specific terminal on the basis of the MAC table by filtering an originating MAC address of the corresponding packet; and at least one communication terminal adapted to being assigned an IP address from the switching system by being connected to the switch of the switching system, and adapted to being guaranteed QoS using a bandwidth reserved in the switch of the switching system via the MAC address of the VoIP terminal registered in the MAC table of the switching system.
