Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this
Bright it is described in further detail, it is clear that described embodiment is only a part of embodiment of the present invention,
Rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out all other embodiments obtained under creative work premise, broadly fall into the scope of protection of the invention.
It should be noted that the embodiment of the present invention is applicable to the net of the LAN of electrically-based line communication PLC
In network framework, in this LAN backbone, including the gateway device used as router, at least one expansion
Open up the gateway device in device equipment and multiple access device, and this LAN, at least one extender device altogether
With a multicast address, i.e. share all of equipment of this multicast address and all can receive any of which equipment and send out
The message of the multicast form sent.The network architecture of LAN based on PLC is not carried out specifically by the present invention
Limit, can be home network, it is also possible to the LAN constituted by large-scale remote power device cluster.
In order to solve in this PLC LAN, the IP address possessed due to access device is not at current local area network
IP address network segment in cause surfing the Net and need manual operation with solve problem, the present invention proposes
A kind of network collocating method, so that the IP address network segment in monitoring LAN obtains with access device
IP address inconsistent time, extender device can carry out network weight according to the network configuration message received
Open, thus so that the access device connecting this expander can disconnect and reconnect to this extender device
Access node, and then so that this access device can reacquire the IP address net in now LAN
IP in section, it is achieved upper net operation.
Below by specific embodiment, technical scheme involved in the present invention is described in detail, the present invention
Include, but are not limited to following example.
Owing to, in this LAN backbone, this network configuration scheme is to be worked in coordination with by gateway device and extender device
Realize, therefore, be described from gateway device and extender device respectively.
After extender device powers on, if gateway device powers on not yet, then access device is being set by expander
After standby acquisition IP address failure, may be by user setup one secondary ip address, then on gateway device
After electricity, access device now will not reacquire IP address, in order to avoid using due to access device
IP address do not cause, in the LAN IP address network segment, the problem that cannot surf the Net, can use with lower section
Formula, as it is shown in figure 1, a kind of network collocating method provided for the embodiment of the present invention, with gateway device side be
Example, the method includes:
Step 101: gateway device electrifying startup.
Step 102: gateway device sends the network configuration message of multicast form to each extender device, its
In, described gateway device and extender device share a multicast address, and described network configuration message is used for referring to
Show that extender device is restarted.
When gateway device completes electrifying startup, whether the access device no matter current extensions device equipment connects has
Standby IP address, gateway device all can be disappeared by the network configuration sending multicast form to each extender device
The mode of breath, it is achieved the network of extender device is restarted, thus, allow the connection node of extender device restart,
I.e. make extender device disconnect with access device, and re-establish connection.So, access device is the most permissible
Obtain IP address, and normally online.
Preferably, when gateway device completes electrifying startup, it is achieved that again joining each extender device
Put, but, after gateway device electrifying startup, it is possible that the operation of the artificial modified address network segment,
This manual operation also results in the IP address of the access device in current local area network not in the address of LAN
Cannot surf the Net in the network segment, therefore, after ensureing gateway device electrifying startup, access device keeps energy
The state of enough online, the embodiment of the present invention additionally provides another kind of network configuration scheme, as in figure 2 it is shown, should
Scheme comprises the following steps:
Step 201: send the net of multicast form when gateway device completes electrifying startup to each extender device
Network configuration message.
Step 202: after gateway device electrifying startup, is periodically detected the address network segment of current local area network.
Step 203: when gateway device detects that address network segment changes, send out to each extender device
Sending the network configuration message of multicast form, wherein, described gateway device and extender device share a multicast
Address, described network configuration message is used for indicating extender device to restart.
In embodiments of the present invention, gateway device as access this LAN router device, serve to
Close important effect.After each equipment all successful connections in this LAN, and access device is by dynamic
After the mode of state acquisition IP address gets IP address and online, gateway device needs this LAN
IP address is monitored, and can be detection the most automatically, it is also possible to triggered by some Action Events and carry out
Detection.If this LAN is home network, then this gateway device can be router device.
If this gateway device detects that the address network segment of this LAN changes (artificially changing address network segment),
Form the address network segment after a renewal, due to the ground the most in the updated, IP address of access device now
In the network segment of location, and owing to access device now has possessed IP address, therefore, can not reacquire
IP address in address network segment after renewal, such result is: the IP address that access device possesses is not
In the IP address network segment that LAN is current.Therefore, access device can be caused normally to surf the Net.
And in embodiments of the present invention, once gateway device detects that the address network segment of this LAN becomes
Change, then each extender device that can share multicast address in LAN based on PLC sends multicast shape
The network configuration message of formula, restarts to indicate each extender device to carry out network.Carry out at extender device
After network is restarted, access device will reconnect to corresponding extender device, and carries out network configuration,
I.e. obtain the IP address in the IP address network segment after updating, and then realize this access device and be connected to network
Purpose.
As it is shown on figure 3, the another kind of network collocating method provided for the embodiment of the present invention, with extender device
As a example by side, the method comprises the following steps:
Step 301: extender device receives the network configuration message of the multicast form that gateway device sends.
Step 302: extender device carries out network according to the network configuration message of this multicast form and restarts.
Wherein, the network configuration message of this multicast form powers at gateway device and sends afterwards.
Owing to the scheme of extender device side is corresponding with the scheme of gateway device side, can refer to gateway device side
