Terms related to embodiments of the present disclosure are explained below.
Passive optical network (Passive Optical Network, PON): a single fiber bi-directional optical access network employing a point-to-multipoint (P2 MP) architecture.
Network cutting: network cutover, also called network migration, refers to the operation of a physical or logical change to the network, typically the operation of the line or device being used, directly affects the traffic carried thereon.
The broadband remote access server (Broadband Remote Access Server, BRAS) is an access gateway for broadband network application, is a bridge between the broadband access network and the backbone network, and provides a basic access means and management functions of the broadband access network.
Fort machine: in a specific network environment, in order to ensure that the network and data are not invaded and damaged by external and internal users, various technical means are used to monitor and record the operation behaviors of operation and maintenance personnel on devices such as servers, network devices, security devices, databases and the like in the network.
An optical modem: also called a single port optical transceiver, optical modem, is a device similar to a baseband digital modem, except that the baseband digital modem is accessed by a dedicated optical fiber line, which is an optical signal. The optical signal conversion and the interface protocol conversion are connected to the router after the conversion, so long as the optical fiber exists, the optical cat is required to convert the optical signal.
As described above, when a broadband service sharing one PON port with a private line service fails, the PON port may be cut to remove the failure of the broadband service, and the information of the virtual local area network (Virtual Local Area Network, VLAN) on the inner layer or outer layer of the PON port may be changed, so that the private line service is interrupted, in the related art, only the private line user can wait for reporting the service interruption, and then arrange the engineers for on-site positioning, so that the average time for resolving a single user failure is approximately 3 hours, the time for resolving the failure is longer, and the satisfaction of the private line user is reduced.
Therefore, the present disclosure provides a network connection control method, by acquiring online status information of a private line IP address of a target user equipment accessing a network in a private line manner, determining whether the private line IP address is online, and acquiring broadband dialing virtual local area network information of the target user equipment accessing the network in a broadband dialing manner using the same passive optical network interface when the target user equipment accesses the network in the private line manner, and controlling the target user equipment to access the network in the private line manner by using the private line IP address according to the broadband dialing virtual local area network information under the condition that the private line IP address is not online, it is possible to automatically obtain a change of the broadband dialing virtual local area network information and automatically repair the private line service according to the change, thereby improving efficiency of solving the private line service fault.
Fig. 1 is a flowchart illustrating a network connection control method according to an exemplary embodiment. The method shown in fig. 1 may be applied, for example, to a device interaction fort in the system of fig. 2.
Referring to fig. 1, a method 10 provided by an embodiment of the present disclosure may include the following steps.
In step S102, online status information of a private line internet protocol IP address of the target user equipment accessing the network in a private line manner is obtained.
In some embodiments, for example, in a conventional metropolitan area network system, when a target user device accesses the network in a private line manner, the target user device accesses the network via a target private line broadband remote access server, and the device interaction fort can collect online status information of a private line IP address in the target private line broadband remote access server at a first preset frequency. Specific embodiments of network connection control in a conventional metropolitan area network system can be seen with reference to fig. 3A, 3B and 4.
In other embodiments, for example, in the novel metropolitan area network system, when the target user equipment accesses the network in a private line manner, the target user equipment accesses the network via the pooled broadband remote access server, and the device interaction fort can collect the online state information of the private line IP address in the pooled broadband remote access server at a third preset frequency. Specific embodiments of network connection control in a new metropolitan area network system can be seen with reference to fig. 5 and 6.
In some embodiments, for example, the online status of the private line IP address may be obtained based on an address resolution protocol (Address Resolution Protocol, ARP) protocol.
In step S104, the first virtual local area network information of the target user equipment accessed to the network in the broadband dialing mode is obtained, and the same passive optical network interface is adopted when the target user equipment accesses to the network in the private line mode and when the target user equipment accesses to the network in the broadband dialing mode.
In some embodiments, for example, in a conventional metropolitan area network system, when the target user equipment accesses the network in a broadband dialing mode, the target user equipment accesses the network via a target dialing broadband remote access server, and the device interaction fort may collect an online record of a broadband dialing account number of the target user equipment from the target dialing broadband remote access server at a second preset frequency, so as to obtain broadband dialing virtual local area network information (i.e., first virtual local area network information) of the target user equipment.
In other embodiments, for example, in the novel metropolitan area network system, when the target user equipment accesses the network in a broadband dialing mode, the target user equipment accesses the network via the pooled broadband remote access server, and the device interaction bastion machine may collect an online record of the broadband dialing account number of the target user equipment from the pooled broadband remote access server at a fourth preset frequency, so as to obtain broadband dialing virtual local area network information of the target user equipment.
In some embodiments, for example, when a PON access private line service is opened for a target user, before installation on site, a broadband dial-up account corresponding to the private line service one-to-one may be opened on a server of a local remote user dial-in authentication service (Remote Authentication Dial In User Service, radius) so that the target user accesses the network through the private line and the broadband dial-up at the same time. The specific embodiments can be seen in fig. 4 and 6.
In some embodiments, for example, the virtual local area network VLAN information may be a logical port identification or the like.
In step S106, in the case that it is determined that the private IP address is not on-line according to the on-line status information of the private IP address, the second virtual local area network information of the target user equipment accessed to the network in the broadband dialing manner is obtained.
In some embodiments, when the private line IP address is found to be not on-line, the virtual local area network information (i.e., the second virtual local area network information) of the currently on-line broadband dialing may be obtained, and the current broadband dialing virtual local area network information of the target user equipment may be obtained from the on-line record of the broadband dialing account number. For example, the device interaction fort may collect, from the target dial-up broadband remote access server, an online record of the broadband dial-up account number of the target user device at a second preset frequency, and obtain broadband dial-up virtual local area network information (i.e., second virtual local area network information) of the target user device from the online record.
In other embodiments, for example, in the novel metropolitan area network system, the device interaction fort machine may collect, from the pooled broadband remote access server, an online record of the broadband dialing account number of the target user device at a fourth preset frequency, and obtain the broadband dialing virtual local area network information of the target user device from the online record.
In step S108, the target ue is controlled to access the network in a private line manner by using the private line IP address according to the first vlan information and the second vlan information.
In some embodiments, it may be determined whether the second vlan information is the same as the first vlan information, that is, the vlan information of the broadband dialing after the private IP address is not on-line may be compared with the vlan information of the broadband dialing when the private IP address is on-line, to determine whether the vlan information of the broadband dialing has changed. And under the condition that the second virtual local area network information is different from the first virtual local area network information, namely the broadband dialing virtual local area network information is changed before and after the disconnection of the private line IP address, modifying the virtual local area network information in the private line configuration information corresponding to the target user equipment according to the second virtual local area network information, for example, modifying the virtual local area network information in the private line configuration information into the second virtual local area network information, so that the target user equipment can access the network in a private line mode again by utilizing the private line IP address according to the modified virtual local area network information.
According to the network connection control method provided by the embodiment of the disclosure, by acquiring the online state information of the private line Internet Protocol (IP) address of the network accessed by the target user equipment in a private line mode, judging whether the private line IP address is online or not, and acquiring the broadband dialing virtual local area network information of the network accessed by the same passive optical network interface in a broadband dialing mode when the target user equipment is accessed by the network in the private line mode, under the condition that the private line IP address is not online, controlling the target user equipment to access the network in the private line mode by utilizing the private line IP address according to the broadband dialing virtual local area network information, automatically finding whether the private line service of the PON access mode is blocked or not through timing, and automatically recovering the PON access private line service blocked by the uplink logic link change can be realized, so that the efficiency of solving the private line service fault can be improved, the duration of single user fault can be reduced from 180 minutes to within 5 minutes, and the satisfaction of the private line user can be improved.
Fig. 2 is a schematic diagram illustrating a network connection control system according to an exemplary embodiment. As shown in fig. 2, the system includes: devices connected through the network interact with the fort 202, the target user modem 204, and the remote user dial-in authentication server 206, for example, may be connected through a fiber optic broadband network.
The device interaction fort 202 may be configured to perform the method shown in fig. 1, for example, the device interaction fort may poll the BRAS device every five minutes (the first preset frequency, the second preset frequency, the third preset frequency, and the fourth preset frequency may be different, for example, 60 seconds, 50 seconds, 120 seconds, and 80 seconds, respectively, or the same, for example, 4 minutes, 5 minutes, or 6 minutes, etc.), collect the online IP address of the PON access private line service and VLAN information in the online dialing account, and if the IP address of the private line service is found to be not online and the VLAN information in the online record of the dialing account is changed, actively modify the data configuration (mainly the VLAN information therein) of the private line service in the private line BRAS.
The remote user dial-in verification server 206 is configured to obtain, according to the identification information of the target user equipment for accessing the network in the private line manner, the identification information of the target user equipment for accessing the network in the broadband dial-in manner.
The target subscriber modem 204 may also be coupled to the target subscriber device (e.g., a subscriber router) for configuring the target subscriber device to access identification information of the network in a broadband dial-up manner. The PON of the subscriber is connected to the optical modem, for example, by a single-uplink connection to a single OLT, and the specific connection method may refer to fig. 3A and fig. 5. The dialing account numbers corresponding to the private line service one by one can be opened in the local radius server 206, and the dialing account numbers are set in the PON access optical modem of the user.
In some embodiments, the target user device accesses the network through the dedicated line based on a bridge mode in a target user modem to which it is connected, and accesses the network through the broadband dial-up based on a routing mode in the target user modem. In the field installation link of the PON access private line service, the PON access optical modem may be set to a "route+bridge" mode, so that both the IP address and the dial-up account number of the private line user may be set, and for a specific embodiment, refer to fig. 4 and fig. 6.
