Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
Example 1
The method aims to solve the problem of automatic address allocation according to the access conditions of a wired WAN port, an uplink optical port and a WIFI MESH in a bridge mode. For the condition that the wired WAN port, the uplink optical port and the WIFI MESH of the FTTR sub optical cat are not accessed, the embodiment of the invention provides the following core technical scheme:
step 101, detecting whether the FTTR sub-optical cat wired WAN port, the uplink optical port and the WIFI MESH are connected to the FTTR main cat in real time.
Step 102, when the wired WAN port, the uplink optical port and the WIFI MESH of the FTTR sub optical cat are not connected to the FTTR main cat, the FTTR sub optical cat starts a DHCP service of the FTTR sub optical cat and distributes addresses for the down-hanging PC; and forces Down/Up (off-first-on operation) wired LAN PHY and WiFi interfaces to cause the Down terminal release/re (release-first-acquisition operation) to reacquire IP.
Step 103, the address allocated by the down-hanging terminal and the FTTR sub-cat are in the same network segment, and at this time, the configuration management of the device can be performed by using the allocated address.
Example 2
The method aims to solve the problem of automatic address allocation according to the access conditions of a wired WAN port, an uplink optical port and a WIFI MESH in a bridge mode. Whether the wired WAN port, the uplink optical port and the WIFI MESH are connected or not, the corresponding different addresses can be automatically allocated according to the access conditions of the wired WAN port, the uplink optical port and the WIFI MESH, and the technical scheme is as follows:
referring to fig. 1, a specific implementation procedure of embodiment 2 of the present invention is shown.
When a user uses a specific FTTR sub-cat, a PC is prepared to be connected to the LAN port of the FTTR sub-cat for configuration management. The device is powered on, and the FTTR sub-cat is operated in the bridge mode.
Step 201: and detecting whether the wired WAN port, the uplink optical port and the WIFI MESH of the FTTR sub optical cat are accessed to the FTTR main cat in real time.
Step 202: if the FTTR sub-optical cat is not connected with the wired WAN port, the uplink optical port and the WIFI MESH and is not networked, the FTTR sub-optical cat starts the DHCP service of the FTTR sub-optical cat to distribute addresses to the Down-hanging PC, forces the Down/Up wired LAN PHY and the WiFi interface, and prompts the Down-hanging terminal release/release to acquire the IP again. The address allocated by the down-hanging terminal is in the same network segment with the FTTR sub-modem, and the user PC can use the allocated address to perform configuration management on equipment.
Step 203: if the wired WAN port or the uplink optical port or the WIFI MESH of the FTTR sub optical cat is accessed to the FTTR main cat, the FTTR sub optical cat can close the DHCP service of the FTTR sub optical cat, the equipment does not provide any DHCP service, the FTTR main cat takes over the allocation address, and releases the address originally acquired by the lower hanging terminal, so that the lower hanging terminal requests the FTTR main cat for new address allocation again, namely, the Down/Up wired LAN PHY and the WiFi interface are forced, and the lower hanging terminal release/update is prompted to acquire IP from the FTTR main cat again. The FTTR sub-optical cat bridge interface also acquires the main cat IP, at the moment, the addresses distributed by the FTTR sub-optical cat bridge interface and the lower hanging terminal are in the same network segment with the FTTR main cat, the configuration management of the FTTR sub-optical cat is carried out by accessing the address of the FTTR sub-optical cat bridge interface, and the internet surfing can also be carried out.
Step 204: when the wired WAN port or the uplink optical port or the WIFI MESH is accessed, the network cable or the optical fiber is dialed or the WIFI MESH networking is disconnected, and the system detects that the wired WAN port or the uplink optical port and the WIFI MESH are not connected in any mode and can acquire a DHCP OFFER or a DHCP ACK packet, at the moment, the FTTR sub optical cat equipment is started to provide an address allocation service for the down-hanging terminal, and the original acquired FTTR main cat address of the down-hanging terminal is released, so that the down-hanging terminal requests new address allocation to the FTTR sub optical cat again.
Step 205: when the hot plug of the wired WAN port or the uplink optical port of the device or the WIFI MESH networking fails or succeeds, the networking conditions of the wired WAN port, the uplink optical port and the WIFI MESH are automatically detected, and the actions of step 202 and step 203 are repeated to realize an automatic allocation switching mechanism.
For embodiment 1 and/or embodiment 2 above, the DHCP service centrally manages all IP network configuration data and is responsible for DHCP requests for the down-hanging terminals, but the IP network generally provides only an IP address auto-configuration function in the routing mode, and does not provide an IP address auto-configuration function in the bridging mode.
In this regard, the present application uses the PC as a bridge between the DHCP service in the FTTR main cat and the FTTR sub-cat and the down-hanging terminal (i.e., the PC receives the DHCP request of the down-hanging terminal, sends the DHCP request to the DHCP server in the FTTR main cat or the FTTR sub-cat, and sends the IP address allocation information corresponding to the DHCP server to the down-hanging terminal), thereby implementing accurate and rapid automatic allocation of the IP address.
For the above embodiment 1 and/or embodiment 2, when the DHCP server allocates an IP address to the down-hanging terminal, the allocation time is limited, and beyond this time, the DHCP server will withdraw the IP address, and if the DHCP server needs to continue to allocate the IP address, the IP address may change, thereby affecting the efficiency of receiving the address by the down-hanging terminal, and possibly causing other problems of confusion and discomfort to the user; also, in embodiment 2, the down-hanging terminal may receive the address allocated by any DHCP server from the FTTR main cat or the FTTR sub-cat, but if the addresses allocated by the two servers are inconsistent, the efficiency of receiving the address by the down-hanging terminal is also affected, which may also cause a problem of discomfort to the user.
In contrast, the address recognition module and the address synchronization module are arranged in the PC, and the address recognition module is used for recognizing and recording the IP addresses allocated to each lower hanging terminal for the first time when the FTTR sub-cat is in the bridge mode; and the address synchronization module is used for modifying the IP address content distributed by the DHCP server to enable the IP address content corresponding to each down-hanging terminal recorded by the address identification module to be consistent when any DHCP server of the FTTR main cat or the FTTR sub-cat distributes an address, and sending the synchronized IP address to the corresponding down-hanging terminal, thereby solving the problem that the IP address is possibly changed for the same down-hanging terminal.

the FTTR sub-optical cat is connected with a PC; when address allocation of the down-hanging terminal is carried out through DHCP service of the main cat of the FTTR, a bridge port of the sub-optical cat of the FTTR and the address allocated by the down-hanging terminal are in the same network segment with the main cat of the FTTR, and the PC carries out configuration management on the sub-optical cat of the FTTR by accessing the bridge port address of the sub-optical cat;
the PC is used as a bridge between a DHCP service in the FTTR main cat and the FTTR sub-cat and a DHCP request of the down-hanging terminal, the PC receives the DHCP request of the down-hanging terminal, sends the DHCP request to a DHCP server in the FTTR main cat or the FTTR sub-cat, and sends IP address allocation information of the corresponding DHCP server to the down-hanging terminal;
an address identification module and an address synchronization module are arranged in the PC, and the address identification module is used for identifying and recording the IP address which is allocated to each down-hanging terminal for the first time when the FTTR sub-cat is in the bridge mode; and the address synchronization module is used for modifying the IP address content distributed by the DHCP server to enable the IP address content corresponding to each down-hanging terminal recorded by the address identification module to be consistent when any DHCP server of the FTTR main cat or the FTTR sub-cat distributes an address, and sending the synchronized IP address to the corresponding down-hanging terminal.
