    摘要： An apparatus and a method for providing a QoS for a multi protocol label switching (MPLS) traffic are provided. According to the apparatus and the method, a label and an experimental (EXP) are extracted from an MPLS packet input to an MPLS network system, and then applied to a predetermined hash function to generate at least one hash value. Also, a QoS policy is applied to an MPLS session, and the MPLS packet is forwarded. Therefore, the QoS for transmitting the MPLS packet input to the MPLS network system can be ensured.

    摘要： Technology for forming a virtual private network (VPN) is provided. A VPN gateway that supports mobility with a connection node having a virtual home address (HoA) and a care of address (CoA) includes a mobility support unit, a data security unit, and a virtual address converter. When a packet is transferred from the connection node, the mobility support unit sustains a binding relationship between a home address (HoA) of the connection node and the changed CoA, and processes a mobility tunnel for the packet, thereby generating a first conversion packet. The data security unit performs a security test of the first conversion packet. The virtual address converter converts the HoA of the connection node, which is a source address of the first conversion packet in which the security test is complete, to a private network internal address that can be used in the VPN, thereby generating a second conversion packet.

    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.
