Description
Technical Field
The present invention relates to the field of broadband access communication technologies, and in particular, to a method and an apparatus for network interconnection.
Background
The home gateway is a network device located in a user home, is a hub for connecting an external network and the user home network, and provides rich and efficient network services for daily life of people. In order to increase the number of home gateway access devices or improve the coverage and signal strength of a wireless Network, many users may connect a router to a Local Area Network (LAN) port of a home gateway, where the router is located at a relatively far position from the home gateway, and a part of the access devices directly access the home gateway, and another part of the access devices access the home gateway through the router. As shown in fig. 3, the home gateway allocates an address to the access device, the PC1 obtains a private Network address 192.168.1.2 allocated to the home gateway, the router establishes a WAN (Wide Area Network) connection to obtain a private Network address 192.168.1.3 allocated to the home gateway, and the PC2 obtains a private Network address 192.168.2.2 allocated to the router. The WAN connection refers to a virtual channel established when the router accesses an external network. When the PC1 accesses an external network, the message is directly sent to the home gateway, and the Internet is accessed through the home gateway. When the PC2 accesses an external network, the message is sent to the router firstly, and then the message is sent to the home gateway through WAN connection of the router to realize internet access through the router. When the PC1 accesses the PC2, the PC1 first sends the packet to the home gateway, the home gateway searches for the route to 192.168.2.2, finds the default route entry, and forwards the packet to the WAN side, that is, to the external network, and the PC1 fails to access the PC 2.
In order to solve the problem of failure of accessing the PC2 by the PC1, a method for configuring a static route on the LAN side is provided, that is, a static route entry is configured on the home gateway, and the routing entry indicates that all messages with destination addresses of 192.168.2.2 are forwarded from 192.168.1.3, so that the PC1 can access the PC 2. Although this approach enables the PC1 to access the PC2, there are two disadvantages: one is that the PC1 sends a message to the PC2, which has three layers, i.e., an IP layer, to search for a route, and after a route entry is searched, three layers of forwarding are performed. In fact, the PC1 and the router are both down-hanging devices of the home gateway, and the message sent by the PC1 to the router can be directly forwarded by the second-layer bridge without going to the third layer, i.e., the IP layer, to search for a routing entry; a second problem is that once the address acquired by the router WAN connection changes, the user must manually configure a static route, which is inconvenient for the user.

Fig. 3 is a scenario diagram of a home gateway access device according to an embodiment of the present invention, as shown in fig. 3, a PC1 obtains a private network address 192.168.1.2 allocated to a home gateway, a router WAN connects to obtain a private network address 192.168.1.3 allocated to the home gateway, and a PC2 obtains a private network address 192.168.2.2 allocated to the router.
The embodiment of the invention adopts the following method: the home gateway DHCP Server assigns an IP address, e.g., 192.168.1.3, to the router WAN connection. After the WAN connection of the router is allocated with the address, the DHCP Server generates the extension content of the Option121 according to the IP address 192.168.1.3 allocated to the router and the address pool segment of the router, for example, if the address pool segment of the router is 192.168.2.X, the subnet mask is 255.255.255.0, the destination descriptor of the generation Option121 is 24.192.168.2, and the next address is 192.168.1.3. The access device of other LAN ports of the home gateway acquires the address in a DHCP mode, the DHCP Server issues the Option121 content and information such as an IP address, a DNS (Domain Name System), a gateway and the like to the access device, and the access device analyzes the Option121 content and configures the static routing entry into a routing table.
The invention relates to a DHCP Server module, which is a software module in a home gateway. The DHCP Server module monitors a DHCP request message sent by the LAN side access equipment, replies the request message sent by the access equipment, allocates an available private network IP address for the access equipment, simultaneously carries extension option information such as DNS and gateway, and maintains the allocated IP address information and the access equipment information.
The invention relates to a DHCP Option module which is a software module in a home gateway. And the DHCP Option module generates the extension information content of each Option. Before the DHCP Server replies the message to the access equipment, the module acquires all the Option contents and adds the Option contents into the message, and replies the message to the access equipment.
When the WAN connection address of the router changes, the content of the Option of the Option121 is regenerated and is sent to the access equipment again, and the access equipment automatically updates the static routing entry, so that the trouble of configuring the static routing by the user is avoided, and better use experience is brought to the user.

step 204: the DHCP Server sends the IP address allocated to the WAN connection of the router to a DHCP Option module;
step 205: the WAN connection IP address of the router is the next hop IP address of the Option121, and the DHCP Option module generates complete Option121 expansion information by using the destination descriptor and the next hop IP address generated in the step 201;
step 206: the PC1 sends a DHCP Request message, an Option55 requests a List Request List to carry an Option121, and requests to acquire Option121 Option information; the Option55 is an Option carried in a request message sent by the client, and the content in the Option is an Option that the client wants to obtain the extension information from the DHCP server;
step 207: the DHCP Server selects an available IP address and obtains the Option information requested to be obtained by the PC1 from the DHCP Option module;
step 208: the DHCP Option module returns all the Option information requested to be acquired by the PC1, including Option121 options;
step 209: the DHCP Server adds the distributed IP address and all Option information into a reply message;
step 210: the DHCP Server sends the reply message to the PC 1;
step 211: the PC1 receives the DHCP message, analyzes all Option options, and configures the static route in the Option121 Option content into the routing table.

step 303: the destination address is not 192.168.2.X, which shows that the application program accesses the external network, and the next hop IP address of the message is 192.168.1.1 of the IP address of the home gateway;
step 304: the PC1 sends the message to the home gateway;
step 305: the home gateway searches for routing entries and forwards the message from the corresponding WAN connection to the external network;
step 306: matching the upper static directory entry, the next hop IP address of the message is IP address 192.168.1.3 for router WAN connection;
step 307: the PC1 directly sends the message to the router WAN for connection;
step 308: the router WAN connection receives the message and forwards the message to the PC 2.
