摘要： The present invention relates to a method and apparatus for performing IPv6 over IPv4 transition to improve performance of a control server. When an edge router selected by the control server according to a tunnel creation request of an IPv6 terminal receives a tunnel creation request message from the control server, the edge router transmits a tunnel creation response message for the received tunnel creation request message to the IPv6 terminal through the control server, and the edge router performs IPv6 over IPv4 transition through a tunnel created by the IPv6 terminal that received the tunnel creation response message so as to improve the performance of the control server. Therefore, loads of the control server occurred because all terminals set control tunnels to the control server can be prevented, and service extensibility due to the increase in the number of subscribers can be guaranteed.

摘要： A tunneling-based mobility support method and apparatus is provided which supports a mobility of a mobile node in a heterogeneous network regardless of IP versions (IPv4/IPv6). The mobility support apparatus includes a load balancer, a plurality of mobility support servers, and a plurality of end routers each being TCP connected to each of the mobility support servers. When receiving a tunnel establishment request message from the mobile node, the load balancer selects one mobility supports server from a plurality of mobility support servers to control a mobility service for the mobile node. The selected mobility support server selects a plurality of tunnel end addresses of one end router from the plurality of end routers to establish an IP tunnel with the mobile node according to a predetermined criterion, forwards the tunnel establishment request message to the end router, and sends the mobile node a tunnel establishment response message including the tunnel end address of the selected end router.

摘要： 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.
