Disclosed herein are a method and apparatus for processing an application service. The method includes: registering a user using a visual network service and at least one physical entity supporting the visual network service; mapping at least one virtual entity corresponding to the at least one physical entity; in response to the user's entering a visual network service space, displaying the at least one virtual entity on a terminal device of the user; and confirming a user input for the at least one virtual entity and controlling an operation of the at least one physical entity corresponding to the at least one virtual entity.

Method and apparatus for processing visual network service

A trust reality service brokering apparatus located on an edge cloud receives a context rule, analyzes event data of at least one physical entity connected to the edge cloud based on the context rule, and transmits an action command to a physical entity or virtual entity corresponding to the event when it is determined that an event has occurred according to an analysis result.

Brokering apparatus and brokering method for trusted reality service

Disclosed are a method of controlling a process based on a network operation mode and an apparatus therefor. A process controlling method performed in a network device includes determining an operation mode for an operating system of the network device, determining an entity for controlling a process based on the determined operation mode, and controlling the process through the determined entity. According to the present invention, it is possible to control a process lifecycle through the same interface regardless of the network operation mode.

Method for controlling process based on network operation mode and apparatus therefor

Provided are a human-tracking method and a robot apparatus. The human-tracking method includes receiving an image frame including a color image and a depth image, determining whether user tracking was successful in a previous image frame, and determining a location of a user and a goal position to which a robot apparatus is to move based on the color image and the depth image in the image frame, when user tracking was successful in the previous frame. Accordingly, a current location of the user can be predicted from the depth image, user tracking can be quickly performed, and the user can be re-detected and tracked using user information acquired in user tracking when detection of the user fails due to obstacles or the like.

Human-tracking method and robot apparatus for performing the same

Disclosed are a system for managing virtual private networks (VPNs) includes: terminals configured to transmit user data; a manager configured to transmit information for concealing networks and managing the VPNs; border gateways configured to decrypt the user data and perform a network address translation (NAT) procedure and a filtering procedure on the decrypted user data based on the information; and servers configured to receive the user data subjected to the NAT procedure and the filtering procedure, wherein the filtering procedure is a procedure discarding the user data to be transferred to the servers that are not allowed so as to allow the terminals to access only the allowed servers, the NAT procedure is a procedure changing an Internet protocol (IP) address used in a first network to an IP address used in a second network, and the first network and the second network are different networks.

System for managing virtual private network and method thereof

Provided is a radio frequency identification (RFID) tag device. The RFID tag device includes memory which stores ID information and a second count value, and a certification unit which performs a certification process according to a keyed hash value received from the outside and a result of a comparison between first and second count values received from the outside, and adjusts the second count value.

RFID tag device and method of recognizing the same

A security method in a server-based mobile IP system is provided. Specifically, in the security method, general data is securely exchanged in addition to a control message that is exchanged between a mobile node and a server or between mobile nodes. Specifically, provided is a method of securely exchanging data by using a mobile node including an mPAK execution module generating necessary keys by exchanging key information with the server while performing a mutual authentication process and negotiating the security policy; and a security module setting a security policy that is negotiated with the corresponding node and applying the security policy to data according to the set security policy when transmitting the data.

Security method of mobile internet protocol based server

Provided is a method of establishing a user centric virtual network. The method includes: performing a first tunneling operation between a first tunnel end and an address translation device, which are connected to a first private network, and a tunnel relay device; performing a second tunneling operation between a second tunnel end and an address translation device, which are connected to a second private network, and the tunnel relay device; and performing a third tunneling operation between the tunnel relay device and an end client, wherein a virtual IP is allocated to each of the first and second tunnel ends, the address translation devices, the end client, and the tunnel relay device; and each of the first to third tunneling operations connects routing information on the virtual IP to a corresponding tunnel.

User centric virtual network and method of establishing the same

In a plurality of virtual tunnel routers including a first virtual tunnel router and a second virtual tunnel router, the first virtual tunnel router and the second virtual tunnel router request virtual network prefix information from a tunnel mapping controller. When the tunnel mapping controller generates virtual network prefix information of the first virtual tunnel router and the second virtual tunnel router, respectively, and transmits the same along with information of a list of adjacent virtual tunnel routers, the first virtual tunnel router and the second virtual tunnel router create a tunnel. With the tunnel established, the virtual network prefix information received by the first virtual tunnel router and second virtual tunnel router, respectively, is linked so that direct communication can be performed between the first virtual tunnel router and the second virtual tunnel router.

Method of network-based communication in virtual network environment

The present invention relates to tunneling an IPv6 packet through an IPIv4 network. In using a tunneling method upon transmitting an IPv6 packet in an IP network, when destination nodes desired to be communicated are located within the same IPv6 prefix network, IPv6 prefix information is added for the management of a tunnel entry. Hence, tunneling information on terminals located within the same IPv6 prefix network can be managed as one tunnel entry. Accordingly, the time consumed when retrieving a tunnel entry can be reduced.

Tunneling IPv6 packet through IPv4 network using a tunnel entry based on IPv6 prefix and tunneling IPv4 packet using a tunnel entry based on IPv4 prefix

The present invention provides a server load balancing apparatus using MPLS session labels. The server load balancing apparatus includes a packet analyzing unit, a load balancing processing unit, a session label switching unit, a session managing unit, and a session label managing unit. The packet analyzing unit inspects whether a session label has been attached to a received packet, analyzes header information of the received packet to learn session information, and attaches a session label to a header of the received packet. The load balancing processing unit assigns a server to a session of the received packet without the session label attached. The session label switching unit hardware-switches the received packet with the session label attached using only the session label information. The session managing unit manages and maintains relevant information and states of sessions. The session label managing unit manages the session label.
