Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. Based on the embodiments herein, a person of ordinary skill in the art would be able to obtain all other embodiments based on the disclosure herein, which are within the scope of the disclosure herein.
The network device synchronizes and updates the routing information through the routing protocols such as OSPF (Open Shortest Path First ) protocol, ISIS (Intermediate System to Intermediate System, intermediate system to intermediate system) protocol, BGP (Border Gateway Protocol ) and the like, and calculates the corresponding routes based on the bandwidth, overhead (Cost), priority and the like of the links.
In addition, in the IPv4 network and the IPv6 network, the network device may also control the routing protocol to calculate, issue and receive the route through a routing policy formed by matching rules such as ACL (Access Control Lists, access control list) or IP address prefix list, so as to forward the IP packet (including the IPv4 packet and the IPv6 packet) based on the route. The network device simply forwards the IP message based on the route and does not care about the user data encapsulated inside the IP message.
But many network devices can forward IP messages, and also can perform advanced processing such as application performance monitoring, traffic recognition, video analysis, AI (Artificial Intelligence ) training and learning on user data encapsulated inside the IP messages. These advanced processes may occupy resources of the network device's CPU (Central Processing Unit ), GPU (Graph Processing Unit, graphics processor), memory, etc. In the related art, when the network device forwards the IP packet based on the route, the use condition of various resources in the network device is not considered, which has a high probability of causing overload of the network device, and further causing packet loss, service interruption and other situations.
In order to solve the above-mentioned problems, the embodiments of the present application provide a routing processing method, which is applied to a network device, where the network device may be a router, a switch, or a device with a routing function. In the routing processing method, the corresponding relation between the resource parameter threshold values of various monitoring objects and the overload routing policy is prestored in the network equipment. The network equipment monitors the resource parameters of various monitoring objects in the network equipment, acquires a target overload routing strategy matched with the use condition of the resources in the network equipment by utilizing the monitored resource parameters of various monitoring objects and the corresponding relation, further executes corresponding load shedding processing operation according to the target overload routing strategy, reduces the message processed by the network equipment, and further reduces the probability of packet loss, service interruption and other conditions caused by the overload of the network equipment.
The following describes in detail the routing processing method provided in the embodiment of the present application through a specific embodiment.
As shown in fig. 1, an embodiment of the present application provides a routing processing method, which is applied to a network device, and includes steps S11-S13.
Step S11, monitoring resource parameters of various monitoring objects in the network equipment.
In the embodiment of the application, the monitoring object in the network device may include, but is not limited to, objects such as traffic data, CPU, GPU, storage, and the like. The network device can monitor the flow data of the monitored object of the network device in real time and acquire the resource parameters of various flow data in the network device, such as the size of the flow data, the speed of the flow data, the CPU utilization, the GPU utilization, the storage space utilization and the like.
Step S12, if the resource parameter of the first monitoring object in the plurality of monitoring objects is monitored to be larger than the resource parameter threshold of the first monitoring object, a target overload routing strategy corresponding to the resource parameter threshold of the first monitoring object is obtained according to the corresponding relation between the pre-stored resource parameter threshold of the plurality of monitoring objects and the overload routing strategy, and the overload routing strategy is used for reducing the message processed by the network equipment.
In the embodiment of the application, the corresponding relation between the resource parameter threshold values of the various monitoring objects and the overload routing policy is prestored in the network equipment. For each monitoring object, the network device may set one or more resource parameter thresholds, and correspondingly set a corresponding overload routing policy for each resource parameter threshold of the monitoring object. For example, the network device sets 2 resource parameter thresholds for the CPU monitoring object, respectively, sets a corresponding overload routing policy 1 for the threshold a and a corresponding overload routing policy 2 for the threshold b.
The first monitoring object may be any one of a plurality of monitoring objects, which is not limited. In the process of monitoring the resource parameters of various monitoring objects in the network equipment, if the network equipment monitors that the resource parameters of a first monitoring object in the various monitoring objects are larger than the resource parameter threshold of the first monitoring object, searching the corresponding relation comprising the resource parameter threshold of the first monitoring object from the corresponding relation prestored in the network equipment, and taking the overload routing strategy comprising the searched corresponding relation as a target overload routing strategy.
The messages mentioned in the embodiments of the present application may be IPv4 messages or IPv6 messages, which are not limited.
Step S13, according to the target overload routing strategy, the load shedding processing operation for the route in the network equipment is executed.
In the embodiment of the present application, the target overload routing policy is used to reduce a packet processed by the network device, and correspondingly, according to a load shedding processing operation executed by the target overload routing policy, the load shedding processing operation is a processing operation for reducing a packet processed by the network device, that is, a processing operation for reducing a load of the network device.
After the target overload routing strategy is obtained, the network equipment executes load shedding processing operation on the routes in the network equipment according to the target overload routing strategy so as to achieve the aim of reducing the load of the network equipment by adjusting the route.
In the technical scheme provided by the embodiment of the application, the corresponding relation between the resource parameter threshold values of the various monitoring objects and the overload routing strategy is prestored in the network equipment. The network equipment monitors the resource parameters of various monitoring objects in the network equipment, acquires a target overload routing strategy matched with the use condition of the resources in the network equipment by utilizing the monitored resource parameters of various monitoring objects and the corresponding relation, further executes corresponding load shedding processing operation according to the target overload routing strategy, reduces the message processed by the network equipment, and reduces the probability of packet loss, service interruption and other conditions caused by the overload of the network equipment.
In some embodiments, the number of first monitoring objects may be a plurality, i.e. the network device monitors that the resource parameter of the plurality of first monitoring objects is greater than the resource parameter threshold of the corresponding first monitoring object. In this case, in the step S12, according to the pre-stored correspondence between the resource parameter thresholds of the multiple monitoring objects and the overload routing policies, the obtaining the target overload routing policy corresponding to the resource parameter threshold of the first monitoring object may be: acquiring candidate overload routing strategies corresponding to the resource parameter thresholds of each first monitoring object according to the corresponding relation between the resource parameter thresholds of the plurality of monitoring objects and the overload routing strategies; and selecting the candidate overload routing strategy with the highest priority as a target overload routing strategy.
In the embodiment of the application, the network device sets priority for each overload routing policy. The priority may be set according to the number of devices involved in the overload routing policy, i.e. the greater the number of devices involved in the overload routing policy, the higher the priority, and conversely the lower the priority. Because, the larger the number of devices involved in the overload routing policy, the greater the impact on the network, and the more obvious the effect of alleviating the messages processed by the network devices.
For example, when the load shedding operation is performed according to the overload routing policy 1, the number of devices involved in the overload routing policy 1 is 2, and when the load shedding operation is performed according to the overload routing policy 2, the number of devices involved in the overload routing policy 2 is 1,2>1, so that the priority of the overload routing policy 1 is greater than the priority of the overload routing policy 2.
The priority can also be set according to the number of routes related to the overload routing strategy, so long as the higher the priority is ensured, the more obvious the effect of lightening the message processed by the network equipment is.
In the embodiment of the application, when the resource parameters of the plurality of first monitoring objects are stored to be greater than the corresponding resource parameter thresholds, the overload routing strategy with the highest priority (namely the candidate overload routing strategy) is selected and used as the target overload routing strategy, so that the message processed by the network equipment can be rapidly lightened, and the probability of occurrence of the situations of packet loss, service interruption and the like caused by overload of the network equipment is further reduced.
In the embodiment of the application, the overload routing policy may include at least one of the following:
1) Stopping receiving and releasing new routes;
2) Cancelling the partial route;
3) Lowering the priority of the next hop as the route of the network equipment;
4) Stopping processing the user data in the message;
5) And outputting alarm information.
The overload routing policy may also include other routing policies, as long as the purpose of reducing the packet processed by the network device can be achieved, which is not limited.
Based on the above overload routing policy, when the determined target overload routing policy indicates to stop receiving and issuing a new route, the embodiment of the application further provides a route processing method, as shown in fig. 2, applied to a network device, which may include the following steps:
step S21, monitoring resource parameters of various monitoring objects in the network equipment. See for details the relevant description of step S11 section.
Step S22, if the resource parameter of the first monitoring object in the plurality of monitoring objects is monitored to be larger than the resource parameter threshold of the first monitoring object, a target overload routing strategy corresponding to the resource parameter threshold of the first monitoring object is obtained according to the corresponding relation between the pre-stored resource parameter threshold of the plurality of monitoring objects and the overload routing strategy, and the overload routing strategy is used for reducing the message processed by the network equipment. See for details the relevant description of step S12 section.
Step S23, stopping receiving the new route sent by the downstream device to the network device, and stopping issuing the new route to the upstream device.
In this embodiment of the present application, the downstream device is the next hop of the network device on the path from the source device to the destination device, and the upstream device is the last hop of the network device on the path from the source device to the destination device.
When the target overload routing policy indicates to stop receiving and releasing a new route, the network device stops receiving the new route sent by the downstream device to the network device through the routing protocol, i.e. when the new route is received, the update of the new route into the routing table is refused, such as discarding the new route. In addition, when the target overload routing policy indicates to stop receiving and releasing a new route, the network device stops releasing the new route to the upstream device through the routing protocol.
In the technical scheme provided by the embodiment of the application, the network equipment stops receiving, releasing and introducing the new route, so that the network equipment does not introduce new traffic, further the resource consumption of the network equipment is not increased continuously, and the probability of occurrence of packet loss, service interruption and the like caused by overload of the network equipment is further reduced.
Based on the above overload routing policy, when the determined target overload routing policy indicates to cancel part of the routes, the embodiment of the application further provides a routing processing method, as shown in fig. 3, applied to the network device, which may include the following steps:
step S31, monitoring resource parameters of various monitoring objects in the network equipment. See for details the relevant description of step S11 section.
Step S32, if the resource parameter of the first monitoring object in the plurality of monitoring objects is monitored to be larger than the resource parameter threshold of the first monitoring object, a target overload routing strategy corresponding to the resource parameter threshold of the first monitoring object is obtained according to the corresponding relation between the pre-stored resource parameter threshold of the plurality of monitoring objects and the overload routing strategy, and the overload routing strategy is used for reducing the message processed by the network equipment. See for details the relevant description of step S12 section.
Step S33, the first route is withdrawn, and a first route update message is sent to the upstream device, so that the upstream device adds a preset identifier to a second route in the upstream device according to the first route update message, the second route is identical to the destination address of the first route, the next hop indicated by the second route is the network device, and the preset identifier indicates that the second route is invalid.
In this embodiment of the present application, the upstream device is a previous hop of the network device on the path from the source device to the destination device. The first route may be any route in the network device, and the number of first routes may be one or more. The specific number can be defined according to actual requirements. For example, the number of first routes may be 1, 2, 3, or the like. The first route update message may be implemented by using LSA (Link State Advertisement ) messages, or may be implemented by using other messages, which is not limited.
When the target overload routing policy indicates to withdraw part of the routes, the network device withdraws the first route through the routing protocol and sends a first route update message to the upstream device. The first route update message indicates that the network device has withdrawn the first route. After the upstream device receives the first route update message, the network device is determined to cancel the first route, and then a second route of which the next hop in the upstream device is the network device is acquired, and a preset identifier is added for the second route.
In the technical scheme provided by the embodiment of the application, the network device sends the first route update message to the upstream device, so that the upstream device adds the preset identifier for the second route of which the next hop is the network device. In this way, when the subsequent upstream device receives the IP packet sent to the destination address in the second route, the second route adds the preset identifier, that is, the second route is invalid, so that the upstream device does not send the IP packet to the network device through the second route, thereby reducing resource consumption of the network device, and further reducing the probability of occurrence of packet loss, service interruption and other situations caused by overload of the network device.
In this embodiment of the present application, in order to determine that an IP packet can be sent to a device corresponding to a destination address in a second route, an upstream device may receive a first route update message, and may also recalculate a route, determine that an address of an entry is the same as the destination address in the second route, and that a next hop is a route of another network device, so as to ensure that the IP packet can be sent to a device corresponding to the destination address in the second route.
Based on the above overload routing policy, when the determined target overload routing policy indicates to lower the priority of the route of the next hop to the network device, the embodiment of the application further provides a route processing method, as shown in fig. 4, applied to the network device, which may include the following steps:
step S41, monitoring resource parameters of various monitoring objects in the network equipment. See for details the relevant description of step S11 section.
Step S42, if the resource parameter of the first monitoring object in the plurality of monitoring objects is monitored to be larger than the resource parameter threshold of the first monitoring object, a target overload routing strategy corresponding to the resource parameter threshold of the first monitoring object is obtained according to the corresponding relation between the pre-stored resource parameter threshold of the plurality of monitoring objects and the overload routing strategy, and the overload routing strategy is used for reducing the message processed by the network equipment. See for details the relevant description of step S12 section.
Step S43, the second route update message is sent to the upstream device, so that the upstream device adjusts the priority of the third route of which the next hop is the network device according to the second route update message, the adjusted priority of the third route is lower than the priority of the fourth route, and the destination address of the fourth route is the same as that of the third route.
In this embodiment of the present application, the upstream device is a previous hop of the network device on the path from the source device to the destination device. The second route update message may be implemented using LSA (Link State Advertisement ) messages, or other messages, which is not limited.
When the target overload routing policy indicates to lower the priority of the next hop as the route of the network device, the network device sends a second route update message to the upstream device through the routing protocol. The second route update message indicates to turn down the next hop as a priority for the network device's route. After the upstream device receives the second route update message, it determines that the next hop is the third route of the network device, and determines a fourth route identical to the destination address of the third route, that is, the third route and the fourth route are equivalent routes. The upstream device adjusts the priority of the third route such that the adjusted priority of the third route is lower than the priority of the fourth route.
Thus, when the upstream device receives the IP packet sent to the destination address in the third route, the priority of the third route is lower than that of the fourth route, so that the upstream device preferentially selects the fourth route and sends the IP packet to the next hop of the fourth route instead of sending the IP packet to the next hop of the third route (i.e., the network device), thereby reducing the resource consumption of the network device and further reducing the probability of packet loss, service interruption and other situations caused by overload of the network device.
In this embodiment of the present application, in order to determine that an IP packet can be sent to a device corresponding to a destination address in a second route, an upstream device may further recalculate a route, and determine that an address of an entry is the same as the destination address in a third route, and a next hop is a route of another network device, so as to ensure that the IP packet can be sent to a device corresponding to the destination address in the third route.
Based on the above overload routing policy, when the determined target overload routing policy indicates to stop processing the user data in the message, the embodiment of the application further provides a routing processing method, as shown in fig. 5, applied to the network device, which may include the following steps:
Step S51, monitoring resource parameters of various monitoring objects in the network equipment. See for details the relevant description of step S11 section.
Step S52, if the resource parameter of the first monitoring object in the plurality of monitoring objects is monitored to be larger than the resource parameter threshold of the first monitoring object, a target overload routing strategy corresponding to the resource parameter threshold of the first monitoring object is obtained according to the corresponding relation between the pre-stored resource parameter threshold of the plurality of monitoring objects and the overload routing strategy, and the overload routing strategy is used for reducing the message processed by the network equipment. See for details the relevant description of step S12 section.
And step S53, the upper layer application module in the network equipment is instructed to stop processing the user data in the message.
In the embodiment of the present application, the consumption of various resources in the network device is mostly caused by advanced processing such as application performance monitoring, traffic identification, video analysis, AI training and learning performed on the user data encapsulated inside the IP packet by the upper layer application module.
In the technical scheme provided by the embodiment of the application, when the network equipment is determined to be overloaded, that is, the resource parameter of the first monitoring object is larger than the resource parameter threshold of the first monitoring object, the network equipment indicates the upper layer application module of the network equipment to stop processing the user data in the message, so that the resource consumption of the network equipment can be greatly reduced, and the occurrence probability of packet loss, service interruption and other conditions caused by the overload of the network equipment is further reduced.
In addition, the network device only instructs the upper layer application module to stop processing the user data in the message, so that the basic forwarding function of the network device is reserved, and the most basic forwarding function is prevented from being influenced due to resource exhaustion.
Based on the above overload routing policy, when the determined target overload routing policy indicates to output alarm information, the embodiment of the application further provides a routing processing method, as shown in fig. 6, applied to a network device, which may include the following steps:
step S61, monitoring resource parameters of various monitoring objects in the network device. See for details the relevant description of step S11 section.
Step S62, if the resource parameter of the first monitoring object in the plurality of monitoring objects is monitored to be larger than the resource parameter threshold of the first monitoring object, a target overload routing strategy corresponding to the resource parameter threshold of the first monitoring object is obtained according to the corresponding relation between the pre-stored resource parameter threshold of the plurality of monitoring objects and the overload routing strategy, and the overload routing strategy is used for reducing the message processed by the network equipment. See for details the relevant description of step S12 section.
Step S63, outputting alarm information indicating network equipment overload to a preset terminal.
In this embodiment of the present application, the network device is associated with one or more terminals, that is, preset terminals. The preset terminal may be a mobile terminal or a server, etc.
When the network equipment is determined to be overloaded, that is, the resource parameter of the first monitoring object is larger than the resource parameter threshold of the first monitoring object, the network equipment outputs alarm information to the preset terminal, and the alarm information indicates the network equipment to be overloaded, so that the purpose of informing an administrator that the use ratio of the monitoring object exceeds the threshold or is exhausted is achieved, the user can process the information in time, and the probability of occurrence of packet loss, service interruption and the like caused by the overload of the network equipment is avoided.
In some embodiments, if it is monitored that the resource parameter of each monitored object in the plurality of monitored objects is less than or equal to the resource parameter threshold of the monitored object, it indicates that the current network device is idle, the network device cancels the execution of load shedding processing operations, such as receiving and releasing a new route, recovering the withdrawn part of routes, lowering the priority of the route of which the next hop is the network device, processing the user data in the message, rejecting to output alarm information, and the like.
By canceling the load shedding processing operation, the network device can process more traffic and user data in the message, so that load balancing in the network is achieved, the resource utilization rate in the network device is improved, and the data processing requirement of the user on the network device is met.
The following describes in detail the routing processing method provided in the embodiment of the present application with reference to the network architecture shown in fig. 7. In fig. 7, server a is the source device, server B and server C are the destination devices, and devices a-D are intermediate network devices. The IP address of server a is 1.1.1.1, the IP address of server B is 2.2.2.2, and the IP address of server C is 3.3.3.3. The routes learned by device a are shown in table 1 and the routes learned by device C are shown in table 2.
TABLE 1
| Destination address | Next hop |
| 2.2.2.2 | Device D |
| 3.3.3.3 | Device D |
TABLE 2
| Destination address | Next hop |
| 2.2.2.2 | Device A |
| 2.2.2.2 | Device B |
| 3.3.3.3 | Device A |
| 3.3.3.3 | Device B |
Taking the communication between the server a and the server B as an example, the path of the communication between the server a and the server B is shown as a path 1-2 shown by the curves of two arrows in fig. 7. The device A adopts OSPF routing, and sets two resource parameter thresholds for GPU utilization, namely 70% and 90% respectively. 70% of the corresponding overloaded routing policies a1 are for stopping receiving and releasing new routes, and 90% of the corresponding overloaded routing policies a2 are for cancelling part of the routes.
If the device a monitors that the GPU utilization of the device a exceeds 70%, the OSPF module of the device a is notified to stop receiving the new route, and does not forward the new route, so that the upstream device (i.e., the device C) does not forward the traffic corresponding to the new route to the device a, but the traffic of the original route (as shown in table 1) continues to be processed normally.
If device a monitors that device a's GPU utilization exceeds 90%, the OSPF module of device a is notified to withdraw some of the routes, e.g., withdraw the route of the first row in table 1 (i.e., the destination address is 2.2.2.2, the next hop is the route of device D), and the withdrawn routes are shown in table 3.
TABLE 3 Table 3
| Destination address | Next hop |
| 3.3.3.3 | Device D |
In addition, the OSPF module of the device a notifies the upstream device (i.e., the device C) to withdraw the corresponding route (i.e., the destination address is 2.2.2.2, and the next hop is the route of the device a) by issuing the LSA message, and the withdrawn route is shown in table 4.
TABLE 4 Table 4
| Destination address | Next hop |
| 2.2.2.2 | Device B |
| 3.3.3.3 | Device A |
| 3.3.3.3 | Device B |
In this way device C no longer forwards traffic with destination address 2.2.2.2 to device a. In addition, device C will recalculate the route after receiving the LSA update message and forward the traffic on the alternate path (path 2 as shown in fig. 7).
In the technical scheme provided by the embodiment of the application, the routing strategy of the network equipment is adjusted by monitoring the resource parameters of the monitored object, so that the flow in the network is guided, and the resources such as the bandwidth, the CPU, the GPU, the storage and the like of the network equipment are reasonably used, thereby avoiding overload. The route update message is issued through the route protocol to trigger the peripheral network equipment to recalculate the route, and the user data is automatically shunted to other network equipment, so that the loads of a plurality of network equipment are balanced, and the resource utilization rate of the network equipment is improved.
