摘要： Provided is a network-based Internet Protocol (IP) multicast service reception controlling apparatus and method. Data corresponding to a multicast channel may be controlled based on a snooping table. The snooping table may be updated based on the service profile. The snooping table may be updated based on a control message, and the control message may be based on whether a user is subscribed to the multicast channel. Whether data corresponding to the multicast channel is to be transmitted may be determined based on whether the data is being transmitted to another user in response to a request from the other user.
摘要翻译：提供了一种基于网络的因特网协议（IP）多播服务接收控制装置和方法。可以基于窥探表来控制对应于组播信道的数据。可以基于服务简档更新窥探表。可以基于控制消息更新窥探表，并且控制消息可以基于用户是否订阅多播信道。是否要发送对应于组播信道的数据可以根据来自其他用户的请求是否正在向其他用户发送数据来确定。

摘要： 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.
摘要翻译：公开了一种用于管理虚拟专用网络（VPN）的系统，包括：被配置为传送用户数据的终端; 配置为传送隐藏网络和管理VPN的信息的管理器; 边界网关被配置为基于该信息解密用户数据并对解密的用户数据执行网络地址转换（NAT）过程和过滤程序; 以及被配置为接收经历了NAT过程和过滤过程的用户数据的服务器，其中，过滤程序是丢弃要传送到不允许的服务器的用户数据以允许终端仅访问允许的用户数据的过程服务器，NAT过程是将第一网络中使用的因特网协议（IP）地址改变为在第二网络中使用的IP地址的过程，并且第一网络和第二网络是不同的网络。

摘要： 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.
摘要翻译：提供了建立以用户为中心的虚拟网络的方法。该方法包括：在连接到第一专用网络的第一隧道端和地址转换设备之间执行第一隧道操作，以及隧道中继设备; 在与第二专用网相连的第二隧道端和地址转换设备之间执行第二隧道操作，以及所述隧道中继设备; 并且在所述隧道中继设备和终端客户端之间执行第三隧道操作，其中虚拟IP被分配给所述第一和第二隧道端中的每一个，所述地址转换设备，所述终端客户端和所述隧道中继设备; 并且第一到第三隧道操作中的每一个将虚拟IP上的路由信息连接到相应的隧道。
