A3: routing rule reverts to the routing rule before access of virtual home gateway.
After the embodiment can guarantee that user no longer needs corresponding business, setting is voluntarily released, or in virtual home
After gateway breaks down, the business under home gateway still is able to operate normally by the access of original link.Work as user first
Cancel corresponding business, mistake occur in the corresponding virtual home gateway of operator's closing or virtual home gateway can not be normal
Operation.It is unreachable to the link of virtual home gateway for entity home gateway real-time detection, at this time by DNS and routing rule
Restore that the state before virtual home gateway is added, so that entity home gateway still is able to run in the way of before,
Upper business can also be run by original network connection.
For example, as shown in figure 5, the configuration process of entity home gateway is as follows when access is superimposed virtual channel:
Step 101, the business such as existing TR069, VOIP, IPTV, Internet are normal on entity home gateway, under hang
The standby DHCP Server by entity home gateway obtains IP address, Gateway (such as: 192.168.1.1), DNS
Server (such as: 192.168.1.1)；
Step 102, after opening virtual service, virtual home gateway will be initialised, complete DNS Relay, NAT and its
The configuration of its network function, and establish the double layer channel with entity home gateway；
Step 103, entity home gateway establish with after the double layer channel of virtual home gateway, entity home gateway (such as:
192.168.1.1 unlatching arrives the heartbeat inspecting of virtual home gateway (such as: 192.168.1.254/253) (such as: ARP on)
ping)；
Step 104, when between entity home gateway and virtual home gateway link up to when, on entity home gateway more
New rule:
The DNS Relay on virtual home gateway is classified as first DNS Server (such as: will in DNS Relay
192.168.1.253 be set as/etc/resolv.conf in first)；
Be arranged routing rule, legal message by policybased routing to physical virtual gateway (such as:
192.168.1.254), remaining message will walk default route (such as: will stamp from wlan0 mouthfuls of message using ebtables
Mark, the message using iptables by destination port for 8080 TCP stamp mark, and the message for stamping mark will pass through vRG
It is routed)；
Step 105, entity home gateway is received hangs standby data message under, and is handled and turned according to rule
Hair；
Step 106, when link is unreachable between entity home gateway and virtual home gateway, on entity home gateway
Update rule:
Restoring the acquired DNS Server of Internet routing WAN connection in DNS Relay is first DNS
Server；
Routing rule is deleted, all messages restore to walk default route；
Step 107, entity home gateway receives and hangs standby data message under, and is carried out according to updated rule
Processing and forwarding.
By the above method and implement to be able to solve entity home gateway to be smoothly linked into while retaining existing network service
The problem of virtual home gateway, simultaneously as the introducing of the business framework of virtual home gateway, provides for subsequent development new business
Guarantee and possibility.
Further, specifically, three kinds of messages can be divided into inside entity home gateway: DNS request, IP packet and its
His message.Wherein DNS message needs the dns server in gateway to be handled, and in this application, DNS message first passes around DNS
The gateway that Relay is opened is forwarded, and is forwarded from dns server；Further, IP packet is then by inquiring road in the application
It is legal by virtual home gateway access internet by table, be not inconsistent normally then by entity home gateway, according to
Original path access.It for other messages, is then handled in such a way that those skilled in the art note, the present invention is herein not
It does and is unfolded.

Go to step 202；If the message is IP packet, 206 are gone to step；If it is other messages, 210 are gone to step；
Step 202, the DNS Relay on entity home gateway receives DNS Request message；If in DNS Relay
First DNS Server is the address DNS Relay (such as: 192.168.1.253) in virtual home gateway, then turns 204；Such as
First DNS Server is the DNS Server acquired by Internet routing WAN connection in fruit DNS Relay, then turns
205；
Step 203, DNS Request will be sent to virtual home gateway by entity home gateway, by virtual home gateway
DNS Relay the DNS Request is further processed；
Step 204, DNS Request will be sent to acquired in Internet routing WAN connection by entity home gateway
DNS Server, is further processed；
Step 205, entity home gateway receives the IP packet for being not intended for the machine (such as: 192.168.1.1), query routing
Table；
Step 206, it if message is labeled with mark, and is then gone to step for the mark there are effective routing rule
208, otherwise go to step 209；
Step 207, IP packet is sent to virtual home gateway (192.168.1.254), and by virtual home gateway do into
The processing of one step；
Step 208, IP packet is sent to destination address by Internet routing WAN connection；
Step 209, it is handled in the way of defaulting in entity home gateway.
It should be noted that all DNS Request message defaults are sent to virtual family in above-mentioned entity home gateway
Front yard gateway is handled, when virtual home gateway is unreachable, according to the configuration method of step 106 in a upper example, DNS
Request message handles automatic fall-back to by the acquired DNS Server of Internet routing WAN connection.Entity man
Legal feature message default is sent to virtual home gateway in the gateway of front yard to handle, when virtual home gateway is unreachable
When, according to the configuration of step 106 in a upper example, such message by automatic fall-back to by Internet routing WAN connect into
Row processing.
IP is distributed by the network equipment that virtual home gateway is lower extension and virtual home gateway, and DNS network address is set.This
