Description

Message sending method and device

Technical field

This application relates to, but is not limited to, the field of communication technology.

Background technique

The devices in the communication network interact with each other through protocol packets. Through the sending and receiving of packets, the discovery of neighbor devices and the exchange of related information are completed. In order to be compatible with protocol communication between various vendors, it is usually possible to ensure interworking between different vendors by formulating common interaction rules and fixed protocol message formats.

In the related art, the protocol packet is sent to the receiving queue of the device port through the protocol process, and the protocol packet is sent by the receiving queue of the device port. In this way, a certain protocol process may generate a large number of protocol packets. For example, the routing protocol process may advertise a large amount of routing information, so that the receiving queue is filled with the protocol packet, causing the protocol packets sent by subsequent protocols to overflow. Discard, thereby affecting communication between other protocol processes.

As shown in FIG. 1, it is a schematic diagram for transmitting an image of a message in the related art. Assume that the service process 1 in the application scenario shown in FIG. 1 is an Intermediate System-to-Intermediate System (ISIS) process, and the service process 2 is a Border Gateway Protocol (referred to as BGP). The process, the service process 3 is a link state routing algorithm, and the algorithm may include an Open Shortest Path First (OSPF) process. In the application scenario shown in Figure 1, the service process 1 (ISIS process) sends a large number of protocol packets to the receive queue and the receive queue is filled. The neighbor keepalive (HELLO) message sent by service process 2 (BGP process) is received. If the queue is full and overflows, the neighboring keepalive (HELLO) packet of the service process 2 (BGP process) will not be sent. After a certain period of time, the BGP process of the peer device will not receive the BGP process of the local device. The neighboring keepalive (HELLO) packet is sent, and the neighbor relationship of the local device is deleted. As a result, all the previously advertised routing information is deleted, which affects the normal forwarding of device data packets.

Embodiments of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments herein may be arbitrarily combined with each other.

The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

The invention provides a message sending method.

Referring to FIG. 2, FIG. 2 is a flowchart of a method for sending a message according to an embodiment of the present invention.

In this embodiment, the packet sending method includes steps 10 to 30:

Step 10: When the first packet is sent, save the first packet in a cache space.

In order to save time for opening the cache space and quickly transmitting the generated message, the embodiment of the present invention may open a buffer space in the device memory or the storage space in advance, and in actual applications, the cache space may not be opened in advance. When a message is sent, for example, when a keep-alive message needs to be sent between the routing devices, the embodiment of the present invention first saves the generated message in a pre-opened cache space.

In step 20, a sending request is initiated to the receiving queue.

After the foregoing packet is saved in the buffer space, a request for sending a packet in the buffer space is initiated to the receiving queue. When receiving the sending request, the receiving queue determines whether the current receiving queue is full. If the current receiving queue is full, the information corresponding to the current receiving queue is full, for example, the feedback information is suspended information; if the current receiving queue is current, the current receiving queue is received. If it is empty, the feedback corresponds to the information that the current receiving queue is empty. Then step 30 is performed.

Step 30: When receiving the indication sending information sent by the receiving queue, send the information according to the indication to send a corresponding number of the first packet in the buffer space to the receiving queue, so that the receiving queue sends a corresponding number of the first packet.

The service process of sending the message performs corresponding processing according to the information fed back by the receiving queue, and pauses the sending of the message in the buffer space when the received feedback information is suspended.

Optionally, in the embodiment of the present invention, when receiving the indication sending information of the feedback of the receiving queue, the service process of sending the packet sends the information according to the indication fed back by the receiving queue, and sends the packet saved in the buffer space to the corresponding quantity. The packet is sent to the receiving queue, and includes: when the number of the packets stored in the buffer space is less than or equal to the number of packets that can be received by the receiving queue, all the packets stored in the buffer space are sent to the receiving queue; If the number of packets to be received is greater than the number of packets that can be received by the receiving queue, the number of packets corresponding to the number of packets that can be received by the receiving queue is sent, and the packet is sent after the sending queue sends the packet. A message left before being sent. In the actual application, the number of sent packets is mainly based on the receiving capability of the receiving queue. The number of sent packets cannot be greater than the number of packets that can be received by the receiving queue. When the number of packets is large, the number of packets corresponding to the receiving capability of the receiving queue is sent each time until all the packets in the buffer space are sent.

When the first packet is sent, the first packet is saved in the buffer space, and the packet is sent to the receiving queue. When receiving the indication sending information sent by the receiving queue, Sending information according to the indication sends a corresponding number of first packets in the buffer space to the receiving queue, so that the receiving queue sends a corresponding number of first packets. In the foregoing manner, when sending a packet, the embodiment of the present invention first saves the packet in the buffer space, and then sends a corresponding number of packets to the receiving queue. For example, when the number of packets is relatively large, the receiving queue can receive the packet. The receiving capability of the packet, the number of packets corresponding to the receiving capability of the receiving queue is sent, and the legacy packet is sent next time, or when the number of packets is small, that is, the number of packets does not exceed the receiving capability of the receiving queue, all the packets are received. The text is sent to the receiving queue, so that the other packets are not discarded because the receiving queue is filled, which ensures normal communication between the devices.

Optionally, FIG. 3 is a flowchart of another method for sending a packet according to an embodiment of the present invention. Steps 11 to 12 in FIG. 3 are: when the first packet is sent, the first packet is saved in the cache space. (ie step 10) the process.

On the basis of the foregoing embodiment shown in FIG. 2, step 10 in this embodiment may include:

In step 11, when the first message is sent, the cache space is opened.

In step 12, the first message is saved in the cache space.

In order to reduce the space pressure of the memory or the storage module, the embodiment may also not open a buffer space in the memory or the storage module in advance, and when the message is sent, the buffer space is opened in the memory or the storage module, and then the packet to be sent is sent. Saved in this cache space.

Optionally, FIG. 4 is a flowchart of still another method for sending a message according to an embodiment of the present invention.

On the basis of the foregoing embodiment shown in FIG. 1, the method provided in this embodiment may further include steps 40 to 50:

Step 40: When the first packet of the first packet in the buffer space is sent to the receiving queue, it is determined whether the legacy packet of the first packet is stored in the buffer space.

Step 50: If the legacy message is stored in the buffer space, the corresponding number of the legacy message is sent to the receiving queue when the message is sent next time.

In this embodiment, after the packet in the buffer space is sent to the receiving queue, it is also determined whether the legacy packet of the sent packet is stored in the buffer space. If the result of the determination is that the legacy space is stored in the buffer space, When the next message is sent, the corresponding number of legacy messages are sent to the receiving queue. For example, a total of 9 keep-alive messages are stored in the buffer space, and the receiving capability of the receiving queue is 5 packets. When 5 packets are sent to the receiving queue, it is determined that there are 4 keep-alive messages left in the buffer space. For example, when the next message is sent, the remaining 4 keep-alive messages are sent. For example, a total of 11 keep-alive messages are stored in the buffer space, and 5 messages are sent to the receiving queue to determine the cache. In the space, there are still 6 keep-alive messages. When the next message is sent, the remaining 5 keep-alive messages are sent, and then it is judged whether there are still messages in the cache space, and it is judged that the cache space is still in the cache space. When there is one keep-alive message, the remaining one keep-alive message is sent when the message is sent for the third time.

Optionally, in the embodiment of the present invention, if there is a legacy message in the buffer space, the next time the message is sent, the legacy message is sent to the receiving queue and the corresponding number of the second message in the buffer space, where The second packet is a packet that is saved after the first packet is sent. Such as continuous in the device A variety of packets are generated. If there are multiple packets in each packet, multiple types and quantities of packets are stored in the cache space on a first-in-first-out basis. When sent to the receive queue, they are first-in, first-out. The principle is sent to the receiving queue, and the quantity sent each time is the number corresponding to the receiving capability of the receiving queue. For example, the receiving queue can receive 5 messages each time, and the service process that sends the message is sent to the receiving queue each time. For the five messages, the number of each message is filled with the receiving queue as the first principle. When the first message is sent, the second message is sent. In an actual application, when multiple types of packets are stored in the cache space, a plurality of packets are first sorted according to the time of entering the cache space, and when the packets are sent, the earliest entry into the cache space is first performed. The message is taken out, and the corresponding number of the received message is sent to the receiving queue according to the criterion of filling the receiving queue. When the received message is not sent, the received message has a legacy message. When the legacy message is placed in the cache space, the position after the various messages are sorted according to the entered time. By analogy, you can continue to cycle.

Optionally, in the embodiment of the present invention, in order to improve the timeliness of the message transmission and ensure the priority transmission of the important message, the next time the message is sent, according to the priority corresponding to the first message and the second report. The priority corresponding to the text sends a corresponding number of legacy messages and/or second packets to the receiving queue.

The priority can be set in advance for different packets. When multiple types of packets are saved in the cache space, the cache space sorts the saved multiple packets each time according to the priority level. For example, the first time When sending a packet, you can first send the packet with the highest priority in the cache space to fill the receiving queue. The maximum number of packets with the highest priority is sent to the receiving queue. The packets in the space are sent. In the actual application, when the number of packets with the highest priority is an integer multiple of the receiving capability of the receiving queue, the packets are sent in the order of the buffers, and then sent after the sending. The packet with the second highest priority in the space, and so on. When the number of packets with the highest priority is not an integer multiple of the receiving capability of the receiving queue, the packet is first sent in the order of the buffer, the last time. When the packet is sent, because the receiving queue is not filled, a corresponding number of packets with the second highest priority are sent in the buffer space to fill up. Receive queue, and so transmitted. In actual applications, if two or more types of packets are stored in the same cache with the same priority, they can be sent on a first-in, first-out basis. It can also be sent in other ways in more implementations.

The embodiment of the invention further provides a message sending device.

Referring to FIG. 5, FIG. 5 is a schematic structural diagram of a message sending apparatus according to an embodiment of the present invention.

The requesting module 20 is configured to: initiate a sending request to the receiving queue.

After the foregoing packet is saved in the buffer space, a request for sending a packet in the buffer space is initiated to the receiving queue. When receiving the sending request, the receiving queue determines whether the current receiving queue is full. If the current receiving queue is full, the information corresponding to the current receiving queue is full, for example, the feedback information is suspended information; if the current receiving queue is current, the current receiving queue is received. If it is empty, the feedback corresponds to the information that the current receiving queue is empty.

The sending module 30 is configured to: when receiving the indication sending information sent by the receiving queue, send, according to the indication sending information, the first number of the first packet saved by the saving module 10 to the buffer space to be sent to the receiving queue, so that the receiving queue Send the corresponding number of first messages.

Optionally, in the embodiment of the present invention, when receiving the indication sending information of the feedback of the receiving queue, the service process of sending the packet sends the information according to the indication fed back by the receiving queue, and sends the packet saved in the buffer space to the corresponding quantity. The packet is sent to the receiving queue, and includes: when the number of the packets stored in the buffer space is less than or equal to the number of packets that can be received by the receiving queue, all the packets stored in the buffer space are sent to the receiving queue; If the number of packets to be received is greater than the number of packets that can be received by the receiving queue, the number of packets corresponding to the number of packets that can be received by the receiving queue is sent, and the packet is sent after the sending queue sends the packet. A message left before being sent. In the actual application, the number of sent packets is mainly based on the receiving capability of the receiving queue. The number of sent packets cannot be greater than the number of packets that can be received by the receiving queue. When the number of packets is large, the number of packets corresponding to the receiving capability of the receiving queue is sent each time until all the packets in the buffer space are sent. When receiving the packet in the buffer space, the receiving queue sends the packet to the corresponding terminal.

When the first packet is sent, the first packet is saved in the buffer space, and the packet sending device sends a request to the receiving queue, and receives the indication sending message sent by the receiving queue. Sending information according to the indication sends a corresponding number of first packets in the buffer space to the receiving queue, so that the receiving queue sends a corresponding number of first packets. In the foregoing manner, when sending a packet, the embodiment of the present invention first saves the packet in the buffer space, and then sends a corresponding number of packets to the receiving queue. For example, when the number of packets is relatively large, the receiving queue can receive the packet. The receiving capability of the packet, the number of packets corresponding to the receiving capability of the receiving queue is sent, and the legacy packet is sent next time, or when the number of packets is small, that is, the number of packets does not exceed the receiving capability of the receiving queue, all the packets are received. The text is sent to the receiving queue, so that the other packets are not discarded because the receiving queue is filled, which ensures normal communication between the devices.

Optionally, the embodiment may further include: a determining module 50, configured to: when the first number of the first packet in the buffer space is sent to the receiving queue, determine whether the legacy packet of the first packet is stored in the buffer space. Text.

Correspondingly, the sending module 30 is further configured to: if a legacy message is stored in the buffer space, send a corresponding number of legacy messages to the receiving queue when the message is sent next time.

Optionally, the sending module 30 in this embodiment is further configured to: if the legacy packet is stored in the buffer space, send the legacy packet and the corresponding amount in the buffer space to the receiving queue when the packet is sent next time. Second message.

In this embodiment, after the packet in the buffer space is sent to the receiving queue, it is also determined whether the legacy packet of the sent packet is stored in the buffer space. If the result of the determination is that the legacy space is stored in the buffer space, When the next message is sent, the corresponding number of legacy messages are sent to the receiving queue. For example, a total of 9 keep-alive packets are stored in the buffer space, and the receiving capability of the receiving queue is 5 packets. When 5 packets are sent to the receiving queue, it is determined that there are 4 keep-alives left in the buffer space. The message is sent to the remaining 4 keep-alive messages when the next message is sent. For example, a total of 11 keep-alive messages are stored in the buffer space, and 5 messages are sent to the receiving queue to determine the message. In the cache space, there are still 6 keep-alive messages. When the next message is sent, the remaining 5 keep-alive messages are sent, and then it is determined whether there are still messages in the cache space, and the cache space is determined. When there is another keep-alive message, the remaining one keep-alive message is sent when the message is sent for the third time.

Optionally, in the embodiment of the present invention, if there is a legacy message in the buffer space, the next time the message is sent, the legacy message is sent to the receiving queue and the corresponding number of the second message in the buffer space, where The second packet is a packet that is saved after the first packet is sent. For example, if multiple packets are continuously generated in the device, and there are multiple packets in each device, multiple types and quantities of packets are stored in the cache space on a first-in-first-out basis, and are sent to the receiving queue. According to the principle of first-in first-out, the method is sent to the receiving queue, and the quantity sent each time is the number corresponding to the receiving capability of the receiving queue. For example, the receiving queue can receive 5 messages each time, and the service process of sending the message is The secondary receiving queue sends five packets, and the number of each transmission is to fill the receiving queue as the first principle. When the first packet is sent, the second packet is sent. In an actual application, when multiple types of packets are stored in the cache space, a plurality of packets are first sorted according to the time of entering the cache space, and when the packets are sent, the earliest entry into the cache space is first performed. The message is taken out to fill up The receiving queue is a criterion, and the corresponding quantity in the received message is sent to the receiving queue. When the received message is not sent, if the received message has a legacy message, the legacy message is placed. The position after sorting multiple messages in the cache space according to the time of entry. By analogy, you can continue to cycle.

Optionally, in the embodiment of the present invention, in order to improve the timeliness of the packet sending and ensure that the important packet is sent preferentially, the sending module 30 is configured to send the legacy packet to the receiving queue and the cache space in the next transmission. The corresponding number of the second packet may be used to: send the corresponding number of legacy packets to the receiving queue according to the priority corresponding to the first packet and the priority corresponding to the second packet when the packet is sent next time.
