Abstract

A method of virtualization of a network application in a network interface card is provided. The network application virtualization method includes: classifying an input packet; mapping the classified packet to a network application; creating a virtual port allocated to the network application; and switching the mapped packet to the virtual port.

Claims

1. A method of virtualization of a network application in a network interface card, comprising:

classifying an input packet;

mapping the classified packet to a network application;

creating a virtual port allocated to the network application; and

switching the mapped packet to the virtual port.

2. The method of claim 1, wherein the classifying of an input packet comprises classifying an input packet according to one or more of the following:

a method of classification by Ethernet type, a method of classification by IP address, a method of classification by MAC (media access control) address of a packet, a method of classification by TCP port, and a method of classification by UDP port.

3. The method of claim 1, wherein the mapping of the classified packet and a network application comprises mapping the classified packet and a network application with reference to available resource information of a physical server where the network application is executed.

4. The method of claim 1, wherein the switching of the mapped packet to the created virtual port comprises:

allocating the mapped packet to a queue;

if the packet length is greater than a queue length for virtualization, discarding the packet; and

if the packet length is less than the queue length for virtualization, switching the packet to the virtual port.

5. The method of claim 4, further comprising storing the number of packets switched to the virtual port or the number of discarded packets.

6. A network application virtualization system comprising:

a traffic classifier for classifying an input packet according to a set classification method;

an application manager for mapping the classified packet to a network application;

a resource manager for managing resources of hardware where the network application is executed; and

a virtual switch for switching the classified packet to the mapped network application based on hardware resource information.

7. The system of claim 6, wherein the set classification method comprises one or more of the following:

a method of classification by Ethernet type, a method of classification by IP address, a method of classification by MAC (media access control) address of a packet, a method of classification by TCP port, and a method of classification by UDP port.

8. The system of claim 6, wherein the application manager stores information on an executable network application.

9. The system of claim 6, wherein the resource manager provides statistics for a history of hardware resource use.

10. The system of claim 6, further comprising a command interface for receiving a command for changing the set classification method.

11. The system of claim 10, wherein the command interface receives a command for updating the functions of the traffic classifier, application manager, and resource manager.

12. The system of claim 6, wherein the virtual switch comprises:

a queue manager for managing a plurality of queues included in the virtual switch and analyzing at least one of the queue for the classified packet;

a scheduler for adjusting the transmission order of the classified packet; and

a port manager for managing matching information of a virtual port allocated to the mapped network application and a hardware port.
