Description
Technical Field
The invention relates to the technical field of home gateways, in particular to a system design and implementation for automatically diagnosing and recovering faults of a home gateway.
Background
With the rapid development of network technology, the digital popularization of home electronic equipment, and the home gateway, as a bridge for connecting various digital equipment to an external network, has become an indispensable part of life, and when encountering network faults, users are most concerned about how to simply and rapidly recover the faults.
At present, network failure occurs in home gateway equipment, network diagnosis depends on a customer service center of a user calling an electric operator, and under the condition that a TR069 network management port is normally controllable, a technician can remotely control the home gateway through a network side management platform. Once the TR069 management port cannot be connected, customer service personnel generally enable users to restart the gateway, the problem that a network is unavailable due to factors such as suspended processes of certain application programs, leakage of memory, overhigh CPU and the like can be solved, the general restarting can solve most of non-configuration problems, if the problem is caused by network configuration change, the restarting cannot be solved, only time can be scheduled for the technicians to go to the gate for checking, and at the moment, the user experience is not good, and the maintenance pressure on a network operator is also great.

Detailed Description
The technical scheme of the patent is further described in detail below with reference to the specific embodiments.
Referring to fig. 1, a system for automatically diagnosing and recovering a fault of a home gateway, when a network fault occurs in a client, a client internet surfing page including a mobile phone, a computer and a tablet is automatically redirected and jumped to a diagnosis page, a user can select a 'device restarting and recovering' button, and the gateway is automatically restarted and invokes a fault recovering module to recover; the system can also select a faulty WAN interface for diagnosis (such as surfing the Internet, voice, IPTV and TR 069) without restarting, firstly judges whether the linking mode of the WAN interface is PPPoE or IPoE according to the diagnosis request of a user for the designated WAN interface, executes corresponding diagnosis, and if dialing or acquiring IP fails according to the current configuration information or acquiring IP but PING gateway fails, automatically starts a fault recovery module and carries out network repair according to the preconfiguration information stored in the configuration file of the gateway system.
The whole framework of the system for automatically diagnosing and recovering the fault of the home gateway is composed of three modules: the system comprises a PPPoE diagnosis module, an IPoE diagnosis module and a fault recovery module.
PPPoE diagnostic module: if the designated diagnosis WAN is PPPoE dialing mode, firstly judging whether the current connection mode is a routing mode or a bridging mode, directly calling the current configuration information to enable the pppd process to dial, calling the PING application program to detect the network of the gateway or other designated IP, and if the PING fails or the dialing fails, enabling the fault recovery module to attempt repairing.
If the current connection mode is the bridge mode, converting the bridge mode into a route mode to start pppd process dialing, and recovering to the bridge mode after diagnosis is finished.
IPoE diagnostic module: if the designated WAN is diagnosed into IPoE mode, firstly judging whether the current connection mode is a route mode or a bridge mode, the route mode directly calls the current configuration information to enable the udhcpc process addressing, and after the IP is taken, calls the PING application program to perform network detection on the gateway or other designated IP, and if the PING fails or the addressing fails, enables the fault recovery module to perform trial repair.
If the current connection is a bridge mode, converting the bridge mode into a routing mode, starting the udhcpc process addressing, and recovering to the bridge mode after diagnosis is finished.
As shown in the flow chart of the fault recovery module in fig. 2, the fault recovery module configures and stores a group of storage nodes for information detection of fault recovery to a configuration file system according to network environments for different service types (for example, internet surfing, voice, IPTV and TR 069), and the storage nodes comprise three parameters: WAN service names, VLAN lists (for example, 46,47,100,201,1024, a plurality of different VLAN IDs are separated by commas), account number and password lists (eg: admin/1234, adminisp/adminis, a plurality of different accounts are separated by commas and are used only in a PPPoE link mode), and each list can be updated and maintained in real time through a TR069 remote management platform to ensure that the lists are consistent with the latest network environment.
The user fails to connect the network by using the current WAN configuration information, can select the corresponding WAN interface to diagnose, re-dial or address, if the network is still not connected, the system automatically calls the fault recovery module, and detects VLAN ID or account password in the preset list in sequence.
Firstly, a first VLAN ID is taken from a VLAN list of a corresponding storage node to create a virtual network interface, a process is started to detect and diagnose, for PPPoE mode, if a diagnosis result returned by the pppd process is Timeout, which indicates that the VLAN line is not connected or a PPPoE server is not available, the next VLAN ID in the list is selected to continue detection, if the result is not Timeout, the diagnosis result returned by the pppd process is judged under the condition that dialing is failed or successful but PING gateway is failed, if parameter negotiation is failed, the current authentication type is automatically modified, and if PAP is changed into CHAP to be redialed; if the user authentication fails, the system automatically and sequentially reads account information from the account password list of the corresponding storage node, replaces the current user name and password to dial again until the detection is successful, and stores the current available configuration information into the storage file system.
For IPoE mode, if the diagnosis result returned by the udhcpc process is "failure in sending DHCP message", which indicates that the VLAN line is not passed or there is no DHCP server, the next VLAN ID in the list is selected to continue to be detected until the addressing is successful and the PING gateway is enabled, and the current available configuration information is stored in the storage file system.
When a fault occurs, if a user selects a 'device restart and restore' button, the system automatically restarts and invokes the fault restore module to perform VLAN detection and diagnosis restoration on each WAN respectively, and the selection can eliminate some problems caused by non-configuration, so that the possibility of network fault restoration is higher.
While the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes may be made without departing from the spirit of the present patent within the knowledge of one of ordinary skill in the art.
