The following is Table 1 indicating the size of the required bandwidth of the application stored in the application information database 1140.

application category required bandwidth APP1, APP3, APP8 and APP 10 Video Streaming (VOD Apps) greatness APP2 and APP4 web browser medium, small APP5 and APP7 weather information littleness APP6 SNS (Social Network Service) middle APP9 search engine middle

Information on the size of the required bandwidth of the application included in the application information database 1140 may be updated whenever a new application is executed.

Meanwhile, here, the application information database 1140 may be located outside the device 1100 . However, this is only an embodiment, and according to another example, the application information database 1140 may be stored inside the device 1100 .

The communication session determiner 1120 according to an embodiment may include a module or hardware for identifying a communication session connected to the device 1100 .

communication device communication session channel first device 4G hot spot second device 3G hot spot third device 2G hot spot 4th device (LAN) 512 KBPS Ethernet cable

Meanwhile, the communication session database 1150 may be located outside the device 1100 . However, this is only one embodiment, and according to another example, the communication session database 1150 may be stored inside the device 1100 .

Dynamic communication session management unit 1130 according to an embodiment based on the size of the required bandwidth of the application determined by the application management unit 1110 and the size of the available bandwidth of the communication session determined by the communication session determining unit 1120, to the application At least one communication session may be allocated.

For example, in order to allocate at least one communication session to an application, the dynamic communication session management unit 1130 performs a sub-component that searches information of an available communication session (hereinafter, referred to as a first sub-component), the actual communication session. A sub-component that determines the size of available bandwidth (hereinafter, the second sub-component), a sub-component that creates an application-communication session mapping database (hereinafter, the third sub-component), and a sub that sets up and manages a virtual network - may include a component (hereinafter, referred to as a fourth sub-component).

The first sub-component according to an embodiment may retrieve information of an available communication session.

The second sub-component according to an embodiment may analyze available bandwidth that can actually be provided for a plurality of communication sessions. For example, assuming that the communication session provides 4G bandwidth, the 4G bandwidth may be shared with a plurality of other devices already connected through a hot spot. In this case, the available bandwidth may be lower than the available bandwidth of the actual communication session. Accordingly, the second sub-component may generate a database regarding the available bandwidth that may be actually provided by the device 1100 .

The available bandwidth may vary for each communication session. For example, device 1100 may determine available bandwidth by determining how many bits should be transmitted over a communication session. Some examples of mechanisms for determining the size of the available bandwidth that can be actually provided by the device 1100 are as follows.

1. Actual Available Bandwidth = Available Bandwidth Size/ Number of Connections Already Connected

2. Actual Available Bandwidth = Available Bandwidth/Number of Connected Applications

3. Actual available bandwidth = available bandwidth - data consumed per second of an existing connection or application

Referring to the following table, the second device and the third device may confirm that the size of the actual available bandwidth is smaller than the size of the available bandwidth. This situation may be due to a connection already present on the devices or applications already running on the device.

Meanwhile, the third sub-component according to an embodiment may create an application-communication database 1160 that stores information about at least one communication session allocated to an application.

The fourth sub-component may configure a virtual network and manage the configured virtual network. The fourth sub-component according to an embodiment may set a virtual IP address to an application based on information about a communication session allocated to the application. For example, the fourth sub-component may generate a plurality of virtual IP addresses based on a communication session allocated for each of the plurality of applications. Via the virtual IP address, the fourth sub-component may allocate a communication session to each of the plurality of running applications.

A virtual IP address (VIP or VIPA) may be assigned to each of a plurality of applications. Incoming traffic is routed to the actual network interface with the VIP address, the server IP address depends on the MAC address of the attached NIC, and only one logical IP address can be assigned to the card. However, the fourth sub-component may use the VIP address to allocate different communication sessions to different applications, respectively. The VIP may be determined according to, for example, Common Address Redundancy Protocol (CARP) and Proxy Address Resolution Protocol (ARP).

A network interface card (NIC) assigns an IP address to a TCP/IP network. Using a virtual IP address, one network interface card can communicate through multiple addresses, via the ifconfig Linux command. For example, an existing interface eth0 can use port 192.168.128.114 as follows.

saturn# ifconfig eth0

eth0 Link encap:Ethernet HWaddr 08:00:27:ce:5f:8e

Using the Iconfig command, the eth0 interface can listen for incoming traffic to the other port 192.168.128.130.

These commands can instruct Linux's TCP/IP stack to listen for packets coming to another port 192.168.128.130, such as packets coming to port 192.168.128.114.

For example, the application manager 1110 may create an application information database 1140 that stores information about an application through the first cloud server 1170 .

According to an embodiment, since processing of the large-capacity database may be delayed according to the hardware specifications of the device, the device 1100 may store the application information database 1140 in the first cloud server 1170 .

According to another example, the communication session determiner 1120 may generate the communication session database 1150 for storing information about the communication session through the second cloud server 1180 .
