Description

Technical Field

[0001] The present invention relates to the technical field of routing optimization, and particularly to an automatic routing optimization method and device. Background Art

[0002] Cloud-network integration is an important engine for promoting digital transformation. With the continuous maturity of the cloud computing industry, business needs and technological innovation drive the acceleration of profound changes in the network architecture in parallel. The cloud and the network are highly coordinated and no longer independent of each other. The development of cloud computing services requires strong network capabilities for support, and the optimization of network resources can also draw on the concept of cloud computing, which is the concept of cloud-network integration. At the same time, the definition of information infrastructure in the new infrastructure emphasizes the importance of computing power and communication network infrastructure, making cloud-network integration a development trend in the cloud computing field and further promoting the construction of network cloudification.

[0003] Currently, the most typical and thorough representative of network cloudification is the 5G core network. As the core functional entity of the communication network, the core network no longer has any dedicated hardware at all. It completely uses x86 general-purpose server hardware, and all services are built on virtual machines and containers, and virtual machines and containers also come from cloud computing technologies. The bearer network after the core network has even introduced SDN (Software Defined Network) technology, separating the routing and forwarding functions from the management and control functions, and building the SDN controller on the cloud platform to provide interface services to upper-layer users. As for the final access network, among the AAU, DU, and CU in the 5G access network, except for the AAU, both the DU and the CU can be built on a virtualization platform. And the international routing optimization system based on cloud-network integration is to build a management and control platform on the cloud platform to control and manage the received international routes on the cloud.

[0004] Currently, the BGP routing protocol is generally used in overseas network construction. In the BGP routing table, there may be multiple routes to the same destination. At this time, BGP will select one of the routes as the best route and only send this route to its peers. In order to select the best route, BGP will compare the BGP attributes of these routes in turn according to the BGP routing preference rules, and international routing optimization is to adjust the BGP routing attributes to achieve the purpose of adjusting the egress route. However, currently in the prior art, this operation is usually performed manually, and the operation process of manual switching is slow, resulting in the inability to quickly restore the network, the network quality cannot be visualized immediately, and the network segment optimization cannot be precise. Summary of the Invention

[0005] Embodiments of the present invention provide an automatic routing optimization method and device, which can automatically adjust the traffic data egress of the route, achieve rapid network restoration, and precisely optimize the received route network segments.

[0006] An embodiment of the present invention provides an automatic routing optimization method, including:

[0007] Real-time monitor the first delay parameter of the first exit of the routing traffic data. After the first delay parameter meets the preset abnormal condition, respectively obtain the second delay parameters of several other exits of the routing except the first exit;

[0008] After testing the several second delay parameters, compare the several second delay parameters with the first delay parameter to determine the second exit that meets the preset working standard;

[0009] Determine the number of abnormal network segments in the first network segment, and select a switching method according to the number of abnormal network segments to switch the traffic data exit of the routing from the first exit to the second exit; wherein, the first network segment is all network segments connected to the first exit in the routing.

[0010] Compared with the prior art, the automatic routing optimization method disclosed in the embodiment of the present invention can realize the rapid recovery of the network and the precise optimization of the routing network segment by real-time monitoring the delay parameter of the main exit of the routing traffic data, determining the standby exit that meets the working standard and automatically switching the traffic data exit of the routing to the standby exit according to the abnormal type after the delay parameter meets the preset abnormal condition.

[0011] Further, the real-time monitoring of the first delay parameter of the first exit of the routing traffic data, and after the first delay parameter meets the preset abnormal condition, respectively obtaining the second delay parameters of several other exits of the routing except the first exit specifically includes:

[0012] Real-time monitor the first delay time and the first packet loss rate of the first exit. When the first packet loss rate exceeds the preset percentage within the preset time period or the first delay time exceeds the preset value within the preset time period, respectively obtain the second delay time and the second packet loss rate of several other exits of the routing except the first exit.

[0013] Establish real-time monitoring for the main exit of the routing traffic data. When the main exit is abnormal, automatically detect the delay parameter of the standby exit, saving the manual judgment time and laying a foundation for rapid network recovery.

[0014] Further, the selecting a switching method according to the number of abnormal network segments to switch the traffic data exit of the routing from the first exit to the second exit specifically includes:

[0015] Detect the number of abnormal network segments. If the proportion of the number of abnormal network segments to the number of the first network segments does not exceed a preset proportion, adjust the egress prefix list of the route so that the traffic data egress of the route is switched from the first egress to the second egress; if the proportion of the number of abnormal network segments to the number of the first network segments exceeds the preset proportion and each of the abnormal network segments belongs to a different entity, adjust the overall cost value of the first egress so that the traffic data egress of the route is switched from the first egress to the second egress.

[0016] Select different switching methods according to the number of abnormal network segments connected to the main egress of the route, and use the different switching methods to switch the traffic data egress of the route to the standby egress, realizing the rapid recovery of the network and the precise optimization of the network segments.

[0017] Further, after switching the traffic data egress of the route from the first egress to the second egress, it further includes testing whether the traffic data egress is successfully switched. Specifically:

[0018] Perform an MTR test on the second egress. If the egress interconnection IP data exists in the network segment path of the second egress, it is determined that the traffic data egress is successfully switched; if the egress interconnection IP data does not exist in the network segment path of the second egress, it is determined that the traffic data egress is switched failed; wherein, the egress interconnection IP data is the IP data pre-entered in the background.

[0019] Determine whether the traffic data egress is successfully switched by testing the IP data in the standby egress, improving the reliability of route optimization.

[0024] When it is determined that the traffic data egress is switched failed or the second egress meeting the preset working standard is not found when testing the second delay parameter, send an alarm message to the user so that the user can manually intervene to troubleshoot after receiving the alarm message.

[0025] If a problem occurs in the export switch, an automatic alarm is sent to notify the administrator to intervene manually for regulation, further ensuring the reliability of route optimization.

[0026] Furthermore, after the export switch of the traffic data of the route is completed, it further includes:

[0027] Real-time monitor the third delay parameter of the first transmission link. When the first delay parameter meets the preset abnormal condition, obtain the fourth delay parameter of the standby link;

[0028] If the fourth delay parameter is less than the third delay parameter, obtain the real-time traffic data, and expand the standby link according to the real-time traffic data with a preset expansion standard;

[0029] Respectively adjust the cost values of the first transmission link and the standby link, so that the traffic data is switched from the first transmission link to the standby link.

[0035] Compared with the prior art, the automatic routing optimization device disclosed in the embodiments of the present invention monitors the delay parameter of the main outlet of the traffic data of the route in real time. After the delay parameter meets the preset abnormal condition, it determines a standby outlet that meets the working standard and automatically switches the traffic data outlet of the route to the standby outlet according to the type of abnormality, which can achieve the rapid recovery of the network and the precise optimization of the route network segment.

[0036] Further, the monitoring module is used to monitor the first delay parameter of the first outlet of the route traffic data in real time.

[0044] Figure 5 It is a schematic structural diagram of an automatic routing optimization device provided by an embodiment of the present invention. Specific embodiments

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] See Figure 1 , which is a schematic flowchart of an automatic routing optimization method provided by an embodiment of the present invention, including:

[0047] S101: Real-time monitor the first delay parameter of the first outlet of the routing traffic data. When the first delay parameter meets the preset abnormal condition, respectively obtain the second delay parameters of several other outlets of the routing except the first outlet;

[0048] S102: When the several second delay parameters are obtained by testing, compare the several second delay parameters with the first delay parameter to determine the second outlet that meets the preset working standard;

[0049] S103: Determine the number of abnormal network segments in the first network segment, and select a switching method according to the number of abnormal network segments to switch the traffic data outlet of the routing from the first outlet to the second outlet; wherein, the first network segment is all network segments connected to the first outlet in the routing.

[0050] An automatic routing optimization method provided by an embodiment of the present invention can realize the rapid recovery of the network and the precise optimization of the routing network segment by real-time monitoring the delay parameter of the main outlet of the routing traffic data. When the delay parameter meets the preset abnormal condition, it determines the standby outlet that meets the working standard and automatically switches the traffic data outlet of the routing to the standby outlet according to the type of abnormality.

[0051] For step S101, specifically, the real-time monitoring of the first delay parameter of the first outlet of the routing traffic data, when the first delay parameter meets the preset abnormal condition, respectively obtaining the second delay parameters of several other outlets of the routing except the first outlet specifically includes:

[0052] Monitor the first delay time and the first packet loss rate of the first exit in real time. When the first packet loss rate exceeds the preset percentage within the preset duration or the first delay time exceeds the preset value within the preset duration, obtain the second delay time and the second packet loss rate of several other exits of the route except the first exit respectively.

[0053] In a preferred embodiment, refer to Figure 2 , for overseas common services, establish real-time monitoring for the traffic data exit of the received route. When the main exit of the traffic data has a 10% packet loss continuously for 5 minutes or the delay increases by more than 20 ms, trigger the international route optimization program.

[0054] After triggering the optimization program, perform a ping test on the abnormal IP, compare the delays and packet losses of different traffic data exits, and synchronously compare and judge whether there is a better upstream exit, then determine the switching target of the traffic data exit as this upstream exit.

[0055] Compared with the prior art, the present invention establishes real-time monitoring for the main exit of the traffic data of the route. When the main exit is abnormal, automatically detect the delay parameters of the standby exit, saving the manual judgment time and laying a foundation for rapid network recovery.

[0056] For step S103, specifically, the method of selecting the switching method according to the number of abnormal network segments to switch the traffic data exit of the route from the first exit to the second exit specifically includes:

[0057] Detect the number of abnormal network segments. If the proportion of the number of abnormal network segments in the number of the first network segments does not exceed the preset proportion, adjust the exit prefix list of the route so that the traffic data exit of the route switches from the first exit to the second exit; if the proportion of the number of abnormal network segments in the number of the first network segments exceeds the preset proportion and each of the abnormal network segments belongs to different entities, adjust the overall cost value of the first exit so that the traffic data exit of the route switches from the first exit to the second exit.

[0058] In a preferred embodiment, refer to Figure 2 , before performing the exit switch, it is also necessary to judge the abnormal type of the traffic data main exit, and then select the switching method according to different abnormal types. Specifically:

[0059] If the number of abnormal network segments does not exceed 20% of the total number of monitored IPs as a whole, it is judged as partial route abnormality or peer-end abnormality, and the exit prefix list is adjusted to complete the adjustment of the outgoing traffic of the individual route segment;

[0060] If the number of abnormal network segments exceeds 20% of the overall monitored IPs, and each abnormal network segment belongs to a different entity, it is determined that there is an abnormality in the operator's export, and the overall cost of the main export is adjusted to complete the overall switching of the traffic data export.

[0061] Compared with the prior art, the present invention selects different switching methods according to the number of abnormal network segments connecting to the main export of the route, and uses the different switching methods to switch the traffic data export of the route to the standby export, realizing the rapid recovery of the network and the precise optimization of the network segment.

[0062] For step S103, further, after switching the traffic data export of the route from the first export to the second export, it further includes testing whether the traffic data export is successfully switched, specifically:

[0063] Perform an MTR test on the second export. If the export interconnection IP data exists in the network segment path of the second export, it is determined that the traffic data export is successfully switched; if the export interconnection IP data does not exist in the network segment path of the second export, it is determined that the traffic data export is switched failed; wherein, the export interconnection IP data is the IP data pre-entered in the background.

[0064] In a preferred embodiment, refer to Figure 2 , after the switching operation is completed, perform an MTR test on the standby export to detect whether the export interconnection IP in the library is included in the path to determine whether the traffic data export is successfully switched.

[0065] Compared with the prior art, the present invention determines whether the traffic data export is successfully switched by testing the IP data in the standby export, improving the reliability of route optimization.

[0066] For step S103, further, after determining that the traffic data export is successfully switched, continuously monitor the first delay parameter of the first export. When it is detected that the first delay parameter is less than the preset threshold range, switch the traffic data export of the route from the second export to the first export.

[0067] Compared with the prior art, the present invention continuously monitors the network quality of the main export of the route after the traffic data export is successfully switched, and switches the route export back to the main export again when the network quality of the main export is restored, which can reduce resource consumption and save operation costs.

[0068] For step S103, further, when it is determined that the traffic data export is switched failed or the second export meeting the preset working standard is not found when testing the second delay parameter, send an alarm message to the user so that the user can manually intervene to troubleshoot after receiving the alarm message.

[0069] As a preferred embodiment, refer to Figure 2 , if the following situations occur during the routing optimization process, the system automatically alarms the on-duty administrator, and the administrator manually accesses to troubleshoot:

[0070] If there is no egress with better network quality, the administrator checks whether the peer is abnormal or the internal network is abnormal;

[0071] If the egress adjustment fails, the administrator checks the device's received routes.

[0072] Compared with the prior art, when an abnormality occurs during the routing switch process, an automatic alarm notifies the administrator, and the administrator determines the type of abnormality based on the alarm information and intervenes to troubleshoot, ensuring the reliability of routing optimization.

[0073] Further, refer to Figure 3 , after the traffic data egress of the route is successfully switched, it further includes:

[0074] S301: Real-time monitor the third delay parameter of the first transmission link. When the first delay parameter meets the preset abnormal condition, obtain the fourth delay parameter of the standby link;

[0075] S302: If the fourth delay parameter is less than the third delay parameter, obtain the real-time traffic data, and expand the standby link according to the real-time traffic data with a preset expansion standard;

[0076] S303: Adjust the cost values of the first transmission link and the standby link respectively, so that the traffic data is switched from the first transmission link to the standby link.

[0077] As a preferred embodiment, refer to Figure 4 , the specific operations for optimizing the transmission link after the routing egress is successfully switched include:

[0078] Real-time monitor the delay and packet loss parameters of the main transmission link. When there is a 10% packet loss for 5 consecutive minutes or the delay increases by more than 10 ms, obtain the delay and packet loss parameters of the standby link; wherein, the standby link maintains a 10M bandwidth when not in use;

[0079] If the delay and packet loss parameters of the standby link are less than those of the main transmission link, obtain the real-time traffic data through SNMP, and expand the standby link according to the real-time traffic data with a redundancy standard of 20%.

[0080] Adjust the cost values of the main transmission link and the standby link respectively, so that the traffic data is switched from the main transmission link to the standby link.

[0081] Further, after the link switching operation is completed, perform an MTR test on the standby link, and determine whether the transmission link is successfully switched according to the transmission interconnection IP pre-entered into the library.

[0082] If the transmission link is successfully switched, continuously monitor the bandwidth of the standby link and perform real-time capacity expansion adjustment on the standby link according to the real-time traffic data. At the same time, continuously compare the delay parameters of the main transmission link and the standby link. When it is detected that the delay parameters of the main transmission link reach the normal working standard, switch the traffic data to the main transmission link. After the traffic data is switched from the standby link to the main transmission link, continuously monitor the main transmission link for 10 minutes. If it is detected that the delay parameters of the main transmission link do not exceed the preset abnormal conditions, reduce the capacity of the standby link to 10M.

[0083] If the transmission link switching fails or it is detected that the delay parameters of the standby link also exceed the preset abnormal conditions, automatically alarm the administrator, and the administrator will manually intervene to troubleshoot the problem according to the alarm information.

[0084] Compared with the prior art, the present invention can realize the rapid recovery of network data transmission by continuously monitoring the delay parameters of the main transmission link. When the delay parameters meet the preset abnormal conditions, expand the capacity of the standby link and automatically switch the traffic data from the main transmission link to the standby link.

[0085] See Figure 5 , which is a schematic structural diagram of an automatic routing optimization device provided by an embodiment of the present invention, including: a monitoring module, a comparison module, and a switching module;

[0086] The monitoring module is used to continuously monitor the first delay parameter of the first exit of the routing traffic data. When the first delay parameter meets the preset abnormal conditions, respectively obtain the second delay parameters of several other exits of the routing except the first exit;

[0087] The comparison module is used to compare the several second delay parameters with the first delay parameter when the several second delay parameters are obtained by testing, and determine the second exit that meets the preset working standard;

[0088] The switching module is used to determine the number of abnormal network segments in the first network segment, and select a switching method according to the number of abnormal network segments so that the traffic data exit of the routing is switched from the first exit to the second exit; wherein, the first network segment is all network segments connected to the first exit in the routing.

[0089] Compared with the prior art, the automatic routing optimization device disclosed in the embodiments of the present invention can realize the rapid recovery of the network and the precise optimization of the routing network segment by monitoring the delay parameter of the main outlet of the routing traffic data in real time, determining a standby outlet meeting the working standard and automatically switching the traffic data outlet of the routing to the standby outlet according to the type of abnormality when the delay parameter meets the preset abnormal condition.

[0090] Further, the monitoring module is used to monitor the first delay parameter of the first outlet of the routing traffic data in real time. When the first delay parameter meets the preset abnormal condition, the second delay parameters of several other outlets of the routing except the first outlet are respectively obtained, specifically including:

[0091] Monitor the first delay time and the first packet loss rate of the first outlet in real time. When the first packet loss rate exceeds the preset percentage within the preset time period or the first delay time exceeds the preset value within the preset time period, respectively obtain the second delay time and the second packet loss rate of several other outlets of the routing except the first outlet.

[0092] Further, the method for selecting the switching method according to the number of abnormal network segments to switch the traffic data outlet of the routing from the first outlet to the second outlet specifically includes:

[0093] Detect the number of abnormal network segments. If the proportion of the number of abnormal network segments in the number of the first network segments does not exceed the preset proportion, adjust the outlet prefix list of the routing so that the traffic data outlet of the routing is switched from the first outlet to the second outlet; if the proportion of the number of abnormal network segments in the number of the first network segments exceeds the preset proportion and each of the abnormal network segments belongs to a different entity, adjust the overall cost value of the first outlet so that the traffic data outlet of the routing is switched from the first outlet to the second outlet.

[0094] Further, after switching the traffic data outlet of the routing from the first outlet to the second outlet, it also includes testing whether the traffic data outlet is successfully switched, specifically:

[0095] Perform an MTR test on the second outlet. If it is detected that there is outlet interconnection IP data in the network segment path of the second outlet, it is determined that the traffic data outlet is successfully switched; if it is detected that there is no outlet interconnection IP data in the network segment path of the second outlet, it is determined that the traffic data outlet is switched failed; wherein, the outlet interconnection IP data is the IP data pre-entered in the background.
