Abstract
The present disclosure provides a method and an apparatus for processing a packet, which are applied to a router in a Border Gateway Protocol (BGP) network, where the router may receive a first flow rule policy sent by a first device, and determine whether a target routing table corresponding to an address to be matched and a next hop address exists in a local routing table of the router. If the local routing table does not have the target routing table, the router forwards the target message of which the received target address is matched with the address to be matched according to the local routing table. Based on the above processing, even if only the first flow rule policy is received, when the local routing table does not have the target routing table, the router can forward the received message according to the local routing table, and does not forward the message according to the invalid flow rule policy, thereby avoiding service interruption.

The Flow Spec policy may be stored in the network device, and when a destination address of a certain message received by the network device matches with the address to be matched, the network device may forward the message according to the next hop address.
A Border Gateway Protocol (BGP) network may include a controller and a plurality of network devices. If a BGP connection exists between two network devices, the two network devices are BGP neighbors to each other. In the BGP network, after a certain network device receives a flow rule policy from a BGP neighbor or a controller, the network device needs to check the validity of an address to be matched and a next hop address in the flow rule policy to determine the validity of the flow rule policy. When determining the validity of the flow rule policy, the network device further needs to obtain, from the BGP neighbor or the controller, a routing table (which may be referred to as a first routing table) corresponding to the address to be matched and a routing table (which may be referred to as a second routing table) corresponding to the next hop address, and then, the network device performs validity check on the address to be matched and the next hop address according to the first routing table, the second routing table, the local routing table, and the longest mask matching rule, respectively.

Detailed Description
The technical solutions in the present disclosure will be described clearly and completely with reference to the accompanying drawings in the present disclosure, and it is to be understood that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The present disclosure provides a method and an apparatus for processing a packet, which may be applied to a router (which may be referred to as a target router), where the target router may be any router in a BGP network, and referring to fig. 1, fig. 1 is a framework diagram of a networking architecture provided by the present disclosure, which is a possible application scenario. The networking includes: router R1, router R2, router R3, router R4, router R5, and router R6. The router R1, the router R2, and the router R3 are boundary routers of 65000 Autonomous Systems (AS), and the router R1, the router R2, and the router R3 are neighbors of an Internal Border Gateway Protocol (IBGP). Router R4, router R5, and router R6 are border routers of AS 65001, and router R4, router R5, and router R6 are IBGP neighbors of each other. Router R1 and router R4 are External Border Gateway Protocol (EBGP) neighbors to each other, router R2 and router R5 are EBGP neighbors to each other, and router R3 and router R6 are EBGP neighbors to each other. The router R1 may be set as a general control router, i.e. all messages need to pass through the router R1. When the router R1 fails, the message can be processed by the router R2 and the router R3. The routing table corresponding to a certain destination address Dest1 in the autonomous domain 65001 is issued to the autonomous domain 65000 through three links of the router R4-the router R1, the router R5-the router R2 and the router R6-the router R1.
Because the controller is not usually configured with a routing table, the router can only receive the flow rule policy issued by the controller. The router can determine the effectiveness of the flow rule policy according to the address to be matched and the next hop address in the local routing table and the flow rule policy. When the local routing table of the router does not have a routing table (i.e. a target routing table) corresponding to the address to be matched and the next hop address in the flow rule policy, that is, the flow rule policy is invalid, the router forwards the received message according to the local routing table. Based on the above processing, even if only the flow rule policy is received, when the local routing table does not have the target routing table, the router can forward the received message according to the local routing table, and does not forward the message according to the invalid flow rule policy, thereby avoiding service interruption.
Referring to fig. 2, fig. 2 is a flowchart of a message processing method provided by the present disclosure, where the method is applied to a target router in a BGP network, and the method may include the following steps.
S201: and receiving a first flow rule strategy sent by the first equipment.
The first flow rule strategy comprises an address to be matched and a next hop address. The address to be matched and the next hop address can be set by technical personnel according to business requirements and used for controlling the transmission of the message of which the destination address is matched with the address to be matched according to a specified path, and the address to be matched can be an interface address of a certain network device or a network address of a subnet containing a plurality of network devices. The first device may be an EBGP neighbor of the target router, an IBGP neighbor of the target router, or a controller.
In an embodiment of the present disclosure, the target router may receive a flow rule policy (i.e., a first flow rule policy) sent by the first device. For example, the target router may receive the first flow rule policy from its EBGP neighbor, may receive the first flow rule policy from its IBGP neighbor, and may receive the first flow rule policy directly from the controller.
S202: and judging whether a target routing table corresponding to the address to be matched and the next hop address exists in a local routing table of the target router.
Wherein the target router may receive Update messages for BGP neighbors, including EBGP neighbors and IEBGP neighbors, to generate the local routing table. When a link in the network fails, the target router may also receive an Update message of a BGP neighbor to delete the routing table corresponding to the link.
In the embodiment of the present disclosure, after receiving the first flow rule policy, the target router may analyze the first flow rule policy to obtain an address to be matched and a next hop address in the first flow rule policy. Then, the target router may determine whether a routing table (i.e., a target routing table) corresponding to the address to be matched and the next-hop address exists in its local routing table. When the target router determines that the target routing table exists in the local routing table, the target router may determine that the address to be matched and the next hop address are valid, that is, may determine that the first flow rule policy is valid. When the target router judges that the target routing table does not exist in the local routing table, the first flow rule strategy is invalid at the moment.
S203: if the local routing table does not have the target routing table, forwarding the target message of which the received destination address is matched with the address to be matched according to the local routing table.
In the embodiment of the present disclosure, when the target router determines that the target routing table does not exist in the local routing table, if the target router receives a message (i.e., a target message) whose destination address is matched with the address to be matched, that is, the destination address of the target message is the address to be matched, or the destination address of the target message belongs to a subnet corresponding to the address to be matched. At this time, the target router needs to forward the target packet according to the local routing table.
Optionally, the target router may forward the target packet according to the optimal routing table in the local routing table, so as to improve packet forwarding efficiency. Step S203 may include the following processing procedures: determining a routing table to be selected matched with a destination address of a target message in a local routing table; determining an optimal routing table in the routing table to be selected according to a preset routing table lookup rule; and sending the target message to an interface corresponding to the next hop address in the optimal routing table to complete the forwarding processing of the target message.
The preset routing table lookup rule can be set by a technician according to experience. For example, the preset routing table lookup rule may be determined according to the longest mask matching rule, or the preset routing table lookup rule may also be determined according to the management distance of the routing table and the metric value of the routing table, and the number of routing tables matching the destination address in the local routing table of the target router may be multiple.
In the embodiment of the present disclosure, the target router may first query the local routing table to obtain each routing table (i.e., the routing table to be selected) matching the destination address of the target packet. Then, the target router can determine the optimal routing table in the routing table to be selected according to the preset routing table lookup rule. Finally, the target router can send the target message to the interface corresponding to the next hop address in the optimal routing table, so that the target message is transmitted from the interface to the network device connected with the interface, and the forwarding processing of the target message is completed.
When determining the optimal routing table, the target router may first determine the temporary routing table in the to-be-selected routing table according to the longest mask matching rule. If the temporary routing table is one, the target router can take the temporary routing table as the optimal routing table; if the number of the temporary routing tables is multiple, the target router can determine the temporary routing table with the minimum management distance from the multiple temporary routing tables as the preferred routing table. If the preferred routing table is one, the target router can take the preferred routing table as the optimal routing table; if the preferred routing table is multiple, the target router may determine the preferred routing table with the smallest metric value from the multiple preferred routing tables as the optimal routing table.
Optionally, when the first flow rule policy is valid, the target router may forward the received packet according to the first flow rule policy. The method may further comprise the steps of: if the local routing list has the target routing list, the received target message is forwarded according to the first flow rule strategy.
In the embodiment of the present disclosure, when the target router determines that the target routing table exists in the local routing table, that is, the first flow rule policy is valid at this time. If the target router receives the target message, the target router can forward the target message according to the first flow rule policy.
When the target packet is forwarded, the target router may send the target packet to an interface corresponding to the next hop address in the first flow rule policy, so that the target packet is transmitted from the interface to a network device connected to the interface, thereby completing forwarding processing of the target packet. The next hop address in the first flow rule policy is usually the network address of a certain interface of the target router.
The target router can also send the first flow rule policy to other network devices when the first flow rule policy is valid, so as to implement automatic deployment of the flow rule policy. Accordingly, if the target routing table exists in the local routing table of the target router, the method may further include the following processing steps.
Step one, a next hop address in the first flow rule strategy and a next hop address in the target routing table are modified into a network address of an interface between the target router and the second device.
The second device is a device having a BGP neighbor relationship with the target router, and the second device may be one or multiple devices.
When the target router determines that the target routing table exists in the local routing table, that is, the first flow rule policy is valid, the target router may modify a next hop address in the first flow rule policy and a next hop address in the target routing table into a network address of an interface connected to the second device.
For example, referring to fig. 1, when the target router is router R1, at this time, the second devices may be router R2 and router R3, and router R1 may modify the next hop address in the first flow rule policy and the next hop address in the target routing table to the network address of the interface connected to router R2 itself, and at the same time, modify the next hop address in the first flow rule policy and the next hop address in the target routing table to the network address of the interface connected to router R3 itself.
And step two, sending the modified first flow rule strategy and the modified target routing table to the second equipment, so that the second equipment can forward the received message according to the modified first flow rule strategy and the modified target routing table.
In the embodiment of the present disclosure, the target router may send the modified first flow rule policy and the modified target routing table to the second device, so that the second device forwards the received packet according to the modified first flow rule policy and the modified target routing table.
After the second device receives the modified first-flow rule policy and the modified target routing table, because the target router uniformly modifies the first-flow rule policy and the next-hop address of the target routing table, the second device can also determine that the modified first-flow rule policy is valid, and then can forward the received message according to the modified first-flow rule policy.
In addition, when a link failure occurs in the BGP network, the target router updates the local routing table according to the Update message of the BGP neighbor, which may cause the target router to determine that the first flow rule policy is invalid according to the local routing table, and at this time, the target router sends the Update message for the target routing table to the BGP neighbor. After receiving the Update message, the BGP neighbor may determine that the modified first flow rule policy is invalid.
Therefore, the method and the device can realize the automatic deployment of the flow rule strategy, and further realize the transmission of the BGP network control message according to the specified path.
Referring to fig. 3, fig. 3 is a flowchart of an example of a message processing method provided by the present disclosure, where the method may be applied to the router R4 in fig. 1, and is described as an example of issuing a first flow rule policy to the router R4 by a controller, where the method may include the following steps.
S301: and receiving the first flow rule strategy sent by the controller.
The first flow rule policy includes an address Dest1 to be matched and a corresponding next hop address (a network address of an interface between the router R4 and the router R5 is referred to as a first interface address).
S302: and judging whether a target routing table corresponding to the address Dest1 to be matched and the first interface address exists in the local routing table, if the target routing table does not exist in the local routing table, executing S303-S305, and if the target routing table exists in the local routing table, executing S306-S308.
S303: when a target message with the destination address matched with the address Dest1 to be matched is received, a routing table to be selected matched with the destination address of the target message is determined in the local routing table.
S304: and determining the optimal routing table in the routing table to be selected according to a preset routing table lookup rule.
S305: and sending the target message to an interface corresponding to the next hop address in the optimal routing table to complete the forwarding processing of the target message.

S307: and modifying the first interface address in the first flow rule policy and the first interface address in the target routing table into the network address of the interface connected with the router R1.
S308: and sending the modified first flow rule strategy and the modified target routing table to the router R1, so that the router R1 forwards the received message according to the modified first flow rule strategy and the modified target routing table.
Referring to fig. 4, fig. 4 is a flowchart of an example of a message processing method provided by the present disclosure, where the method may be applied to the router R1 in fig. 1, and is described as an example of issuing a second flow rule policy to the router R1 by a controller, where the method may include the following steps.
S401: and receiving the second flow rule strategy sent by the controller.
The second flow rule policy includes the address Dest1 to be matched and a corresponding next hop address (the network address of the interface between the router R1 and the router R4 is referred to as a second interface address).
S402: and judging whether a target routing table corresponding to the address Dest1 to be matched and the second interface address exists in the local routing table, if the target routing table does not exist in the local routing table, executing S403-S405, and if the target routing table exists in the local routing table, executing S406-S408.
S403: when a target message with the destination address matched with the address Dest1 to be matched is received, a routing table to be selected matched with the destination address of the target message is determined in the local routing table.
S404: and determining the optimal routing table in the routing table to be selected according to a preset routing table lookup rule.
S405: and sending the target message to an interface corresponding to the next hop address in the optimal routing table to complete the forwarding processing of the target message.
S406: and when a target message with the destination address matched with the address Dest1 to be matched is received, sending the target message to an interface corresponding to the second interface address so as to complete the forwarding processing of the target message.
S407: and modifying the second interface address in the second flow rule policy and the second interface address in the target routing table into the network address of the interface connected with the router R2, and sending the modified second flow rule policy and the modified target routing table to the router R2, so that the router R2 forwards the received message according to the modified second flow rule policy and the modified target routing table.
S408: and modifying the second interface address in the second flow rule policy and the second interface address in the target routing table into the network address of the interface connected with the router R3, and sending the modified second flow rule policy and the modified target routing table to the router R3, so that the router R3 forwards the received message according to the modified second flow rule policy and the modified target routing table.
The present disclosure does not limit the execution order of step S407 and step S408.
As can be seen from the above, based on the message processing method of the present disclosure, the router may receive the first flow rule policy sent by the first device, and determine whether a target routing table corresponding to the address to be matched and the next hop address exists in the local routing table of the router. If the local routing table does not have the target routing table, the router forwards the target message of which the received target address is matched with the address to be matched according to the local routing table. Based on the above processing, even if only the first flow rule policy is received, when the local routing table does not have the target routing table, the router can forward the received message according to the local routing table, and does not forward the message according to the invalid flow rule policy, thereby avoiding service interruption.

As can be seen from the above, based on the message processing apparatus of the present disclosure, the router may receive the first flow rule policy sent by the first device, and determine whether a target routing table corresponding to the address to be matched and the next hop address exists in the local routing table of the router. If the local routing table does not have the target routing table, the router forwards the target message of which the received target address is matched with the address to be matched according to the local routing table. Based on the above processing, even if only the first flow rule policy is received, when the local routing table does not have the target routing table, the router can forward the received message according to the local routing table, and does not forward the message according to the invalid flow rule policy, thereby avoiding service interruption.
