Description

TR 069-based network route optimization method and system

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a network route optimization method, system, processor, and storage medium based on TR 069.

Background

TR069 is fully named "Technical Report 069" and is a Technical specification revised by DSL Forum (a non-profit global industry consortium working on developing Broadband networks whose members include leading vendors in the industries of communications, equipment, computers, networks and service providers, now known as "Broadband Forum"), and the specification is a Management Protocol of application layer named "CPE wide area network Management Protocol".

TR069 defines a set of new network management system structure, including management model, interactive interface and basic management parameters, and can effectively implement the management TR069 to the home network device, where the network management Server is called ACS (Auto Configuration Server) and has special IP address and URL; the managed device obtains the URL of the ACS through the DHCP server, and after obtaining the network management IP, the managed device starts to establish the HTTP session according to the URL of the ACS. After the session is established, initialization is required for authentication, and the ACS is required to ensure the validity of the managed device. After the initialization is completed, the network management server can acquire various monitoring information from the CPE. The method has the advantages that: the SNMP function does not need to be configured on the managed device, and if the number of the managed devices exceeds 3000 or more, a large amount of configuration time of the monitored devices is saved. The advantages are two: TR069 is fast to collect information because it uses the HTTP protocol, itself, to transfer structured data information. Therefore, all the required information is collected once and returned once, while the SNMP itself cannot transfer the information, and the information is collected one by one and returned one by one.

With the gradual deepening of the digital development, the equipment in operation of each unit is gradually increased, and compared with the equipment increased by 10-100 times before ten years, even though the operation and maintenance is developed from manual operation and maintenance to tool operation and maintenance and platform operation and maintenance, the operation and maintenance requirements of the current large-scale networking on the operation and maintenance supervision still cannot be met. Meanwhile, the mass IPv6 addresses also increase more operation and maintenance pressure and technical problems for the current machine room operation and maintenance environment. On such a large scale, monitoring network equipment by manual experience and automation becomes a technical bottleneck restricting operation and maintenance work. In the prior art, the requirement on monitoring timeliness is difficult to meet, so that a more intelligent and efficient network route optimization method is introduced to improve the operation and maintenance guarantee capability of managing network equipment and routes.

The meaning of the above terms in this patent may be specifically understood by those of ordinary skill in the art.

The invention provides a TR 069-based network route optimization method, which is shown in a figure 1 and comprises the following steps:

s10: testing all router paths of a data packet transmission route passing from a source CPE to a target CPE through a traceroute command, and collecting an IP address and testing time of each router;

specifically, the traceroute command is a tool used by the linux system to detect the number of routers (gateways) that pass between a user terminal device (source CPE) that issues a packet and a target user terminal device (target CPE). the principle of traceroute is to try to send out a probe packet with the minimum TTL (time to live) to trace the data packet to the gateway through which the target user terminal device passes, and then listen to a response from the gateway ICMP (Internet control message protocol), which is a sub-protocol of the TCP/IP protocol family, for passing control messages between the IP host and the router. The size of the transmission packet is defaulted to 38 bytes. The result of executing traceroute command output includes the IP address and test time of the router, and it is generally default that the source CPE sends three data packets each time, and then the test time of each router includes three delay times, and the number of the sent data packets may be set according to the actual situation. In some cases, the output result may also include the name of the router, the output result being stored in a routing database.

S20: testing all router paths of a data packet transmission route passing from a source CPE to a target CPE through a TR069 protocol, and collecting an IP address and testing time of each router;

the source CPE and the target CPE need to support TR069 protocol. When a user terminal device (CPE) is accessed to a network, the operation of carrying out communication authentication configuration on the CPE is actively executed through a program deployed by an ACS (automatic configuration server). And simultaneously, by utilizing the characteristic that the ACS and the CPE carry out interoperation through a Remote Procedure Call (RPC) method specific to the TR069 protocol, the ACS secondarily sends a configuration file of a request message conforming to the TR069 protocol RPC format to the target CPE, wherein the configuration file comprises IP addresses and test time of all routers passing through a data transmission line. Secondly, the target CPE analyzes the configuration file, acquires the IP address of the router and the test time and puts the IP address and the test time into the configuration file. The target CPE requests the configuration file to the ACS again, the ACS analyzes the configuration file to acquire the TR069 protocol, updates the IP address and the test time of the router from the source CPE to the target CPE, and stores the IP address and the test time into a routing database, wherein the IP address and the test time are acquired by the data acquisition according to the network topology static association stored by the target CPE.

S30: comparing the traceroute command with the test time of the same router IP address acquired by a TR069 protocol, and taking the minimum value of the test time as an optimal path of a data packet transmission route passing between the source CPE and the target CPE;

And comparing the data acquired by the two modes, comparing the delay time of the IP addresses of the same router, taking the minimum value of the delay time as the optimal selection of one path of the data packet transmission route passing between the source CPE and the target CPE, and adding an optimal mark in a routing database.

S40: and selecting the data route passing the most optimal path as the optimal network route.

And accessing the network topology database by taking the IP address of the path marked with the optimal mark in the routing database as a query condition to acquire all router paths of the data packet transmission path passing between the source CPE and the target CPE at this time. And selecting the data route with the most appeared optimal marks as the optimal route selection between the source CPE and the target CPE at this time.

Accordingly, the present invention proposes a TR 069-based network route optimization system, as shown in fig. 2, the system 100 includes: an information collection module 110, a data comparison module 120, a route determination module 130, a routing database 140, and a network topology database 150.

The information acquisition module 110 is configured to test all router paths of a data packet transmission route passing between a source CPE and a target CPE through a traceroute command and a TR069 protocol, and acquire an IP address and test time of each router; the result of executing traceroute command output includes the IP address and test time of the router, and it is generally default that the source CPE sends three data packets each time, and then the test time of each router includes three delay times, and the number of the sent data packets may be set according to the actual situation. In some cases, the output may also include the name of the router, which is stored in the routing database 140. When a user terminal device (CPE) is accessed to a network, the operation of carrying out communication authentication configuration on the CPE is actively executed through a program deployed by an ACS (automatic configuration server). And simultaneously, by utilizing the characteristic that the ACS and the CPE carry out interoperation through a Remote Procedure Call (RPC) method specific to the TR069 protocol, the ACS secondarily sends a configuration file of a request message conforming to the TR069 protocol RPC format to the target CPE, wherein the configuration file comprises IP addresses and test time of all routers passing through a data transmission line. Secondly, the target CPE analyzes the configuration file, acquires the IP address of the router and the test time and puts the IP address and the test time into the configuration file. The target CPE requests the configuration file to the ACS again, and the ACS parses the configuration file to obtain the TR069 protocol, updates the IP address and the test time of the router from the source CPE to the target CPE, which are acquired by the data acquisition, according to the network topology static association stored by the target CPE, and stores the IP address and the test time in the routing database 140.

The data comparison module 120 is configured to compare the traceroute command with test time of the same router IP address acquired by the TR069 protocol, and take the minimum test time as an optimal path of a data packet transmission route passing between the source CPE and the target CPE; comparing the data collected by the two methods, comparing the delay time of the IP addresses of the same router, taking the minimum value of the delay time as the optimal selection of one path of the data packet transmission route passing between the source CPE and the target CPE and adding the optimal mark in the route database

The route determining module 130 is configured to select the data route that has the most optimal route as the optimal network route. The network topology database 150 is accessed by taking the IP address of the path marked with the optimal mark in the routing database as a query condition to acquire all router paths of the data packet transmission path passing between the source CPE and the target CPE. The network topology database 150 stores the association relationship of the current overall network architecture and the IP address of the corresponding device. And finally, selecting the data route with the most appeared optimal marks as the optimal route from the source CPE to the target CPE.
