Abstract

A resource monitoring method comprises the steps of: generating process information including a process identifier, process user, process name, CPU usage, and IO usage; determining at least one first process having the same process user and process name from among a plurality of processes currently being executed; generating first group process information including a group process identifier, total CPU usage, and total IO usage of the determined at least one first process; and monitoring resources of the computing device in units of the generated first group process information.

Claims

1. A SBC (Session Boarder Controller) operating method being performed on a SBC apparatus, the SBC apparatus passing a NAT (Network Address Translation) to be operated in a cloud network accessible to Internet, the SBC apparatus being connectable with a SSW (Soft Switch) through the Internet and performing a predetermined address translation for offering a VoIP (Voice over Internet Protocol), the method comprising:

(a) checking an own public IP address being separated by an association with an own private IP (Internet Protocol) address and the NAT being used in the cloud network; and

(b) analyzing a packet for a VoIP communication when the packet is received from a source VoIP terminal, applying and updating the own public IP address to address information associated with a channel, the address information associated with the channel forming a channel with a target VoIP terminal being included in the packet.

2. The method of claim 1, wherein the step (a) includes

(a-1) checking an own private IP address internally being assigned in the cloud network when a SBC instance is generated;

(a-2) requesting the public IP address accessible to itself from an outside of the cloud network to the NAT; and

(a-3) associating and storing the public IP address being provided from the NAT with the private IP address.

3. The method of claim 1, wherein the step (b) includes at least one of

(b-1) forming a signaling channel associating a URI (Uniform Resource Identifier) address of the source VoIP terminal with the own public IP address to be registered in the SSW;

and

(b-2) forming a media stream channel for generating a call between the source VoIP terminal and the target VoIP terminal.

4. The method of claim 1, wherein the packet includes at least one of source address information of a corresponding packet, destination address information, source URI information, destination URI information and the address information associated with the channel.

5. The method of claim 4, wherein the address information associated with the channel corresponds to address information being used for the registration or forming the signaling channel and is represented by using the own public IP address.

6. The method of claim 4, wherein the step (b-1) includes

changing and determining the destination address information being associated with own address to an address of SSW;

and

applying the own public IP address to update the address information associated with the channel of the corresponding packet.

7. The method of claim 6, wherein the step (b-1) further includes applying the own private IP address to update the source address information of the packet.

8. The method of claim 6, the packet stores a URI (Uniform Resource identifier) of the source VoIP terminal as the source URI information and the destination URI information of the packet.

9. The method of claim 4, wherein the step (b-2) further includes analyzing a response packet provided from the target VoIP terminal and applying and updating own public IP address to the address information associated with the channel of the response packet.

10. The method of claim 9, wherein the step (b-2) further includes

applying and updating the own private IP address to the source address information being associated with the address of SSW;

11. A SBC(Session Boarder Controller) apparatus passing NAT (Network Address Translation) to be operated in a cloud network accessible to Internet, the SBC apparatus being connectable with the SSW (Soft Switch) through the Internet and performing a predetermined address translation for offering VoIP (Voice over Internet Protocol), the apparatus comprising

an IP address checking unit configured to check a own public IP (Internet Protocol) address being separated by being associated with an own private IP address and the NAT being used in the cloud network;

and

a packet updating unit configured to analyze a packet for a VoIP communication when the packet is received from a source VoIP terminal and to update an own public IP address to address information associated with a channel, the address information associated with the channel forming a channel with a target VoIP terminal being included in the packet.

12. The apparatus of claim 11, wherein the IP address checking unit uses the NAT to check to check own private IP address internally being assigned in the cloud network and the public IP address accessible to itself from the outside of the cloud network.

13. The apparatus of claim 12, further comprising:

an IP address storing unit configured to match and store the private IP address checked by the IP address checking unit and the public IP address and

wherein the IP address checking unit applies a change when the change for at least one of the private IP address and the public IP address is generated to provide the changed IP address to the IP address storing unit.

14. The apparatus of claim 11, wherein the packet includes at least one of source address information, destination address information, source URI information, destination URI information and address information associated with the channel.

15. The apparatus of claim 14, wherein the packet analyzes the packet to check whether it is a corresponding packet for a registration, applies the own public IP address and when it is a corresponding packet for a registration and updates the source address information of the packet and the address information associated with the channel to provide the updated source address information and address information to the SSW.

16. The apparatus of claim 15, wherein the packet updating unit decides a corresponding packet as a packet for registering the IP address when the source URI information of the packet and the destination URI information are same.

17. The apparatus of claim 14, wherein the packet updating unit analyzes the packet to check whether it is a packet for forming a signaling channel generating a call between the source VoIP terminal and the target VoIP terminal and applies the own public IP address when it is a packet for forming a signaling channel generating a call between the source VoIP terminal and the target VoIP terminal to update the address information associated with the channel.

18. The apparatus of claim 17, wherein the packet updating unit stores the public IP address of the other SBC apparatus being stored in the address information associated with the channel of a corresponding response packet, when a response packet being corresponded to the packet is received from the target VoIP terminal.

19. The apparatus of claim 18, wherein the packet updating unit stores the public IP address of the other SBC apparatus as the address information associated with the channel when the signaling channel is successfully formed.

20. A storage medium recording a program, the program executing a SBC (Session Boarder Controller) operating method, the SBC operating method being performed on a SBC apparatus, the SBC apparatus passing NAT (Network Address Translation) to be operated in a cloud network accessible to Internet, the SBC apparatus being connectable with the SSW (Soft Switch) through the Internet and performing a predetermined address translation for offering VoIP (Voice over Internet Protocol), the program comprising:

(a) checking an own public IP address being separated by an association with an own private IP (Internet Protocol) address and the NAT being used in the cloud network; and

(b) analyzing a packet for a VoIP communication when the packet is received from a source VoIP terminal, applying and updating the own public IP address to address information associated with a channel, the address information associated with the channel forming a channel with a target VoIP terminal being included in the packet.
