Description

Data processing method and device, electronic equipment and computer readable medium

Technical Field

The embodiment of the application relates to the technical field of internet, in particular to a data processing method and device, electronic equipment and a computer readable medium.

Background

BGP (Border Gateway Protocol) is a dynamic routing Protocol that can be used both between different ASs (Autonomous systems) and within the same AS. When BGP runs inside the same AS, it is called IBGP (Internal BGP); when BGP runs between different ases, it is called EBGP (External BGP). The AS is a group of routers which have the same routing strategy and belong to the same technical management department. The focus of BGP is to control the propagation of routes and to select the best route.

BGP GR (Graceful Restart) is a mechanism that ensures uninterrupted forwarding service when a BGP router is protocol restarted or switched between main and standby boards. Specifically, as shown in fig. 1A, when BGP router a establishes a BGP connection with BGP router B, a port of BGP router a and a port of BGP router B negotiate and determine an execution action of BGP GR. After determining the performing actions for BGP GR, BGP router B enters a mode that assists BGP router A in completing BGP GR. When the BGP router a and the BGP router B are disconnected from each other, the BGP router B keeps forwarding the service traffic to the BGP router a according to the routing information of the BGP router a, and cannot perceive a situation in which the BGP router a disconnects the BGP connection, that is, the BGP router B cannot distinguish whether the BGP router a disconnects the BGP connection normally or disconnects the BGP connection abnormally. When the BGP router A abnormally cuts off BGP connection due to failure, the BGP router B keeps the service flow continuously forwarded to the BGP router A, and the BGP router A cannot continuously forward the service flow due to failure, so that the problem of long-time service flow black holes is caused.

Therefore, how to effectively solve the problem of black holes in the traffic flow generated by the BGP routing device becomes a technical problem to be solved urgently at present.

Detailed Description

The present application will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1B, a flowchart illustrating steps of a data processing method according to a first embodiment of the present application is shown.

This embodiment explains the data processing method provided in this embodiment from the perspective of the first BGP routing device. Specifically, the data processing method provided by this embodiment includes the following steps:

in step S101, when it is detected that a graceful restart function of a second BGP routing device that establishes a BGP connection with a first BGP routing device needs to be started for an operation of the first BGP routing device, a first message for notifying that the graceful restart function of the second BGP routing device is started is sent to the second BGP routing device by using a dynamic capability message, so that the second BGP routing device forwards a traffic flow to the first BGP routing device based on routing information of the first BGP routing device when the first BGP routing device and the second BGP routing device are disconnected from each other.

In an embodiment of the present application, the operation for the first BGP routing device includes at least one of: upgrading operation aiming at the BGP process of the first BGP routing equipment, restarting operation aiming at the BGP process of the first BGP routing equipment and TCP connection operation aiming at the first BGP routing equipment. Specifically, the upgrade operation for the BGP process of the first BGP routing device may be an upgrade operation for the BGP process of the first BGP routing device by a user, for example, when the first BGP routing device prompts the user whether to upgrade for the BGP process of the first BGP routing device, the upgrade operation is executed for the BGP process of the first BGP routing device in response to a click operation for a determination control by the user. The upgrade operation for the BGP process of the first BGP routing device may also be an upgrade operation that the first BGP routing device automatically performs for the BGP process of the first BGP routing device, for example, when the first BGP routing device detects a new version of the BGP process, the upgrade operation is automatically performed for the BGP process of the first BGP routing device. In order to ensure that the first BGP routing device can continuously forward the traffic flow during the upgrade operation performed on the BGP process of the first BGP routing device, the graceful restart function of the second BGP routing device that establishes the BGP connection with the first BGP routing device needs to be started, so that when the BGP connection between the first BGP routing device and the second BGP routing device is disconnected due to the warm restart operation during the upgrade operation, the second BGP routing device forwards the traffic flow to the first BGP routing device based on the routing information of the first BGP routing device. The restart operation performed on the BGP process of the first BGP routing device may be a restart operation performed on the BGP process of the first BGP routing device by a user, for example, in response to the user pressing a restart key of the first BGP routing device when the user presses the restart key of the first BGP routing device, the restart operation performed on the BGP process of the first BGP routing device. In order to ensure that the first BGP routing device can continuously forward the service traffic, the graceful restart function of the second BGP routing device that establishes the BGP connection with the first BGP routing device needs to be started in the process of performing the restart operation for the BGP process of the first BGP routing device, so that when the BGP connection between the first BGP routing device and the second BGP routing device is disconnected due to the restart operation, the second BGP routing device forwards the service traffic to the first BGP routing device based on the routing information of the first BGP routing device. The TCP connection operation for the first BGP routing device may be an operation that, after the BGP connection is established between the first BGP routing device and the second BGP routing device, the TCP connection between the first BGP routing device and the second BGP routing device is disconnected, and the TCP connection needs to be executed for the first BGP routing device and the second BGP routing device. In the process of executing TCP connection operation for the first BGP routing device, in order to ensure that the first BGP routing device can continuously forward traffic, a graceful restart function of a second BGP routing device that establishes a BGP connection with the first BGP routing device needs to be started, so that when the first BGP routing device and the second BGP routing device do not establish a BGP connection, the second BGP routing device forwards traffic to the first BGP routing device based on the routing information of the first BGP routing device. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.

In this embodiment of the present application, the first BGP routing device and the second BGP routing device may both be understood as routing devices based on a BGP protocol, for example, BGP routers. The first BGP routing device and the second BGP routing device are located in at least one of the following networks: public cloud service networks, proprietary cloud service networks, hybrid cloud service networks, and multi-cloud service networks. The BGP connection may be understood as a connection established by the first BGP routing device and the second BGP routing device based on a BGP protocol. The TCP connection may be understood as a connection established by the first BGP routing device and the second BGP routing device based on the TCP protocol. The graceful restart function may be understood as a function for ensuring stability of a network without deleting corresponding routing information when a BGP routing device is disconnected for a short time. The dynamic capability message may be understood as a message used to dynamically send messages due to the dynamic capability. The dynamic capability message may have an initialization field, an acknowledgement request field, a reservation field, an action field, a sequence number field, a capability code field, a capability length field, a capability value field, and the like. In this embodiment, the dynamic capability message may be extended to support an attribute advertisement related to the graceful restart function, that is, to support an attribute of the graceful restart capability message related to the graceful restart function, so as to send a message notifying that the graceful restart function of the second BGP routing device is started or closed. The traffic may be multimedia traffic, such as video traffic, audio traffic, text traffic, image traffic. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.

In some optional embodiments, the first message carries an update parameter for updating a graceful restart function of the second BGP routing device. Such as a restart timeout, a restart flag, an address family flag, etc. Therefore, the graceful restart function of the second BGP routing equipment can be dynamically updated through the update parameter which is carried in the first message and used for updating the graceful restart function of the second BGP routing equipment. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.

In step S102, when the first BGP routing device disconnects from the second BGP routing device, the forwarded service traffic is received based on the routing information of the first BGP routing device by the second BGP routing device.

In some optional embodiments, the method further comprises: when the first BGP routing device reestablishes the BGP connection with the second BGP routing device, send, by using the dynamic capability message, a second message for notifying that the graceful restart function of the second BGP routing device is closed to the second BGP routing device, so that when the second BGP routing device disconnects the BGP connection with the first BGP routing device again, the second BGP routing device deletes the routing information of the first BGP routing device, and forwards the traffic to the other BGP routing devices based on the routing information of the other BGP routing devices. Specifically, when the graceful restart function of the second BGP routing device is turned off, if the second BGP routing device disconnects BGP from the first BGP routing device, the second BGP routing device may determine that the first BGP routing device abnormally disconnects BGP, for example, abnormally disconnects BGP due to a failure. At this time, the second BGP routing device may delete the routing information of the first BGP routing device. Thereby, routing information for the second BGP routing device can be converged quickly. The second BGP routing device may also forward the traffic to the other BGP routing devices based on the routing information of the other BGP routing devices, instead of continuously maintaining forwarding of the traffic to the first BGP routing device, so as to achieve a purpose of quickly recovering the network routing failure. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.

By the data processing method provided by the embodiment of the application, when it is detected that a graceful restart function of a second BGP routing device establishing BGP connection with a first BGP routing device needs to be started for operation of the first BGP routing device, a first message for notifying the start of the graceful restart function of the second BGP routing device is sent to the second BGP routing device by using a dynamic capability message, so that when the first BGP routing device is disconnected from the second BGP routing device, the second BGP routing device forwards service traffic to the first BGP routing device based on routing information of the first BGP routing device; when the first BGP routing equipment and the second BGP routing equipment are disconnected from the BGP connection, receiving routing information and forwarded service flow of the second BGP routing equipment based on the first BGP routing equipment, and compared with the existing other modes, when detecting that the graceful restart function of the second BGP routing equipment establishing the BGP connection with the first BGP routing equipment needs to be started aiming at the operation of the first BGP routing equipment, sending a first message for informing the start of the graceful restart function of the second BGP routing equipment to the second BGP routing equipment by using a dynamic capability message, starting the graceful restart function of the second BGP routing equipment establishing the BGP connection with the first BGP routing equipment as required, and enabling the second BGP routing equipment to sense that the situation of the subsequent BGP connection disconnection of the first BGP routing equipment is normal through the first message, thereby effectively solving the problem of black holes of the service flow generated by the BGP routing equipment.

The dynamic capability message may have an initialization field, an acknowledgement request field, a reservation field, an action field, a sequence number field, a capability code field, a capability length field, a capability value field, etc. In this embodiment, the dynamic capability message may be extended to support an attribute advertisement related to the graceful restart function, that is, to support an attribute of the graceful restart capability message related to the graceful restart function, so as to send a message notifying that the graceful restart function of the second BGP routing device is started or closed. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.

In some optional embodiments, the first message carries an update parameter for updating a graceful restart function of the second BGP routing device, and before starting the graceful restart function of the second BGP routing device based on the first message, the method further includes: updating the graceful restart function of the second BGP routing device based on the update parameter carried in the first message, where starting the graceful restart function of the second BGP routing device based on the first message includes: and starting the updated graceful restart function of the second BGP routing equipment based on the first message. Wherein, the update parameter may be a restart timeout time, a restart identifier, an address family identifier, etc. Therefore, the graceful restart function of the second BGP routing device is updated based on the update parameter carried in the first message, and the graceful restart function of the second BGP routing device can be dynamically updated without renegotiation through a port of the BGP routing device.

Specifically, when the graceful restart function of the second BGP routing device is turned off, if the second BGP routing device disconnects BGP from the first BGP routing device, the second BGP routing device may determine that the first BGP routing device abnormally disconnects BGP, for example, abnormally disconnects BGP due to a failure. At this time, the second BGP routing device may delete the routing information of the first BGP routing device. Thereby, routing information for the second BGP routing device can be converged quickly.

Referring to fig. 3A, a flowchart of steps of a data processing method in the third embodiment of the present application is shown.

In this embodiment, the data processing method provided in this embodiment is described from the perspective of interaction between a first BGP routing device and a second BGP routing device. Specifically, the data processing method provided by this embodiment includes the following steps:

in step S301, when it is detected that a graceful restart function of a second BGP routing device that establishes a BGP connection with a first BGP routing device needs to be started for an operation of the first BGP routing device, a first message for notifying that the graceful restart function of the second BGP routing device is started is sent to the second BGP routing device by using a dynamic capability message.

When it is detected that a graceful restart function of a second BGP routing device that establishes a BGP connection with a first BGP routing device needs to be started for an upgrade operation of a BGP process of the first BGP routing device, a first message for notifying the start of the graceful restart function of the second BGP routing device may be sent to the second BGP routing device by using a dynamic capability message before the upgrade operation is performed for the BGP process of the first BGP routing device, and the second BGP routing device starts the graceful restart function according to the first message, that is, enters a mode assisting the first BGP routing device. After the graceful restart function is initiated, an acknowledgement message for the first message is sent to the first BGP routing device. And when the first BGP routing equipment is disconnected from the second BGP routing equipment due to hot restart operation in the upgrading operation process, the second BGP routing equipment forwards service traffic to the first BGP routing equipment based on the routing information of the first BGP routing equipment. After the hot restart operation in the upgrade operation process is completed, the first BGP routing device and the second BGP routing device reestablish BGP connection.

Referring to fig. 4, a flowchart of steps of a data processing method in the fourth embodiment of the present application is shown.

The present embodiment explains the data processing method provided in this embodiment from the perspective of the first BGP routing device. Specifically, the data processing method provided by this embodiment includes the following steps:

in step S401, when it is detected that a graceful restart function of a second BGP routing device that establishes a BGP connection with a first BGP routing device needs to be started for an upgrade operation of a BGP process of the first BGP routing device, a first message for notifying that the graceful restart function of the second BGP routing device is started is sent to the second BGP routing device by using a dynamic capability message, so that when the first BGP routing device and the second BGP routing device are disconnected from each other, the second BGP routing device forwards a traffic to the first BGP routing device based on routing information of the first BGP routing device.

In this embodiment of the present application, the upgrade operation for the BGP process of the first BGP routing device may be an upgrade operation for the BGP process of the first BGP routing device by a user, for example, when the first BGP routing device prompts the user whether to upgrade the BGP process of the first BGP routing device, the upgrade operation is executed for the BGP process of the first BGP routing device in response to a click operation of the user on the determination control. The upgrade operation for the BGP process of the first BGP routing device may also be an upgrade operation that is automatically performed by the first BGP routing device for the BGP process of the first BGP routing device, for example, when the first BGP routing device detects a new version of the BGP process, the upgrade operation is automatically performed for the BGP process of the first BGP routing device. In order to ensure that the first BGP routing device can continuously forward the traffic flow during the upgrade operation performed on the BGP process of the first BGP routing device, the graceful restart function of the second BGP routing device that establishes the BGP connection with the first BGP routing device needs to be started, so that when the BGP connection between the first BGP routing device and the second BGP routing device is disconnected due to the warm restart operation during the upgrade operation, the second BGP routing device forwards the traffic flow to the first BGP routing device based on the routing information of the first BGP routing device. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.

The first BGP routing device and the second BGP routing device are located in at least one of the following networks: public cloud service networks, proprietary cloud service networks, hybrid cloud service networks, multi-cloud service networks. The BGP connection may be understood as a connection established by the first BGP routing device and the second BGP routing device based on a BGP protocol. The graceful restart function may be understood as a function for ensuring stability of a network without deleting corresponding routing information when a BGP routing device is disconnected for a short time. The dynamic capability message may be understood as a message used to dynamically send messages due to the dynamic capability. The dynamic capability message may have an initialization field, an acknowledgement request field, a reservation field, an action field, a sequence number field, a capability code field, a capability length field, a capability value field, etc. In this embodiment, the dynamic capability message may be extended to support an attribute advertisement related to the graceful restart function, that is, to support an attribute of the graceful restart capability message related to the graceful restart function, so as to send a message notifying that the graceful restart function of the second BGP routing device is started or closed. The traffic may be multimedia traffic, such as video traffic, audio traffic, text traffic, image traffic. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.

In step S402, when the first BGP routing device disconnects from the second BGP routing device, the service traffic forwarded by the second BGP routing device based on the routing information of the first BGP routing device is received.

Since the embodiment of step S402 is similar to that of step S102, it is not repeated herein.

By the data processing method provided by the embodiment of the application, when it is detected that a graceful restart function of a second BGP routing device establishing BGP connection with a first BGP routing device needs to be started for upgrading operation of a BGP process of the first BGP routing device, a first message for notifying the start of the graceful restart function of the second BGP routing device is sent to the second BGP routing device by using a dynamic capability message, so that when the first BGP routing device is disconnected from the second BGP routing device, the second BGP routing device forwards service traffic to the first BGP routing device based on routing information of the first BGP routing device; when the first BGP routing equipment and the second BGP routing equipment are disconnected with each other, receiving routing information and forwarded service flow of the second BGP routing equipment based on the first BGP routing equipment, and compared with the existing other modes, when upgrading operation of a BGP process aiming at the first BGP routing equipment is detected and a graceful restart function of the second BGP routing equipment establishing BGP connection with the first BGP routing equipment needs to be started, sending a first message for informing the start of the graceful restart function of the second BGP routing equipment to the second BGP routing equipment by using a dynamic capability message, starting the graceful restart function of the second BGP routing equipment establishing BGP connection with the first BGP routing equipment as required, and enabling the second BGP routing equipment to sense that the situation of the subsequent BGP connection disconnection of the first BGP routing equipment is normal through the first message, thereby effectively solving the problem of black holes of the service flow generated by the BGP routing equipment.
