摘要： According to an example, to access a surveillance network through a Layer 2 Tunnel Protocol (L2TP) includes a private network IP address is assigned to a public network user device, and a route of a surveillance segment is transmitted to the public network user device, such that, after the route of the surveillance segment is received by the public network user device, an IP address of the L2TP virtual interface of the public network user device is configured as a next-hop of the route. When an access request to a surveillance device in the private network is initiated, a routing table of the public network user device is searched to find a matching route of the surveillance segment according to an IP address of the surveillance device. The access request is transmitted to an L2TP server through the L2TP virtual interface, and forwarded to the surveillance device.

摘要： According to an example, to load balance a group of servers, a service access request message is sent by a client terminal and is received at a load balancing device, wherein a source Internet Protocol address of the request message is an Internet Protocol address of the client terminal of a first protocol version. A server is selected from the group of servers to send the request message. A determination is made as to whether the first protocol version is same as a second protocol version of an IP address of the selected server. If the versions are the same, the request message is sent to the selected server. Otherwise, network address translation is performed to replace the source Internet Protocol address of the request message with an Internet Protocol address of the second protocol version to send the request message.

摘要： A method for detecting an IP address. An access router releases the routes of a detected IP address via a first interface and a second interface, and sets the priority of the route released via said first interface lower than that of the route released via said second interface. After having received by said access router a WEB request by the user via said first interface, the method comprises searching a session record corresponding to said WEB request; establishing by said access router the session record corresponding to said WEB request when the corresponding session record is not found, and returning a redirecting message taking said detected IP address as the re-directed destination IP address; and after having received by said access router via said second interface the message taking said detected IP address as the destination IP address, determining that the user who sent said message is an illegal user.
