Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a message processing method and a network device.
Background
Currently, network devices and components are physical entities connected into a network. The network device has a certain message processing capability, and in general, when the network device performs message processing, it is first necessary to send a message to a control layer through a data layer of the network device, and then the control layer in the network device processes the sent message.
In the prior art, the processing of the messages is to limit the number of the messages sent from the data layer to the control layer by setting a fixed sending threshold, and then the control layer processes a certain number of the messages sent from the data layer. However, in a complicated environment, such a method for setting a fixed uplink threshold is usually not reasonable, for example, when an uplink channel of a data layer is excessively suppressed to make an uplink message too small (i.e. the uplink threshold is small), the processing capability of the control layer is wasted, so that the resources of the control layer cannot be fully utilized, and the processing speed of a normal service is affected. When the uploading channel of the data layer is released to enable the number of the uploaded messages to be too large (namely the uploading threshold is large), the control layer of the network equipment faces a large processing pressure, continuous packet loss occurs, and due to the fact that a large number of messages are uploaded, resources of the control layer cannot meet the requirement of message processing, and therefore services cannot be normally developed.

The network equipment for data communication, which is applied by the message processing method provided by the invention, adopts a distributed system architecture, and the distributed system architecture comprises a main control board positioned at the uppermost layer and one or more layers of service boards. Wherein, each layer of service board can comprise one or more service boards. The main control board and the service board both include two layers, which are a data layer and a control layer.

Similarly, the control layer may also include various functional modules, such as a monitoring unit, a management unit, and a CPU).

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
An embodiment of the present invention provides a method for processing a packet, where as shown in fig. 1, the method includes:
101. and the data layer acquires the packet loss number of the message to be processed in the last time unit of the current time unit according to the message type of the message to be processed and sends the packet loss number of the message to be processed to the control layer.
The message types in the embodiment of the present invention include, but are not limited to: protocol type messages and/or service type messages.
For example, in step 101, the data layer obtains, according to the packet type of the packet to be processed, the packet loss number of the packet to be processed in the last time unit of the current time unit, which specifically includes the following contents:
101a, obtaining the message type of the message to be processed.
101b, reading the packet loss number of the message to be processed in the last time unit of the current time unit in the database according to the message type of the message to be processed.
Illustratively, based on the content in step 101, reading, in the database, the packet loss number of the to-be-processed packet in the last time unit of the current time unit according to the packet type of the to-be-processed packet specifically includes:
a1, obtaining the packet loss number of the message to be processed in the last time unit of the current time unit in the message packet loss number table according to the message type of the message to be processed.

Illustratively, based on the content of a1, the method further includes:
b1, obtaining packet loss numbers of different types of messages in each time unit to form a message packet loss number table, and storing the message packet loss number table into a database.
The following illustrates a process of acquiring the number of lost packets by the data layer in the embodiment of the present invention. Illustratively, the above-mentioned number of lost packets is obtained by timing with a timer of a data layer in the network device. Specifically, in a fixed time period, when the timer starts to time, the data layer starts to count the packet loss number, and when the time reaches, the data layer finishes counting the packet loss number.
Referring to the packet loss statistical flow chart shown in fig. 2, the data layer receives the uplink messages, then determines the received uplink messages, and when the number of the uplink messages exceeds a set value (i.e. the maximum number of protocol messages that can be transmitted), the data layer loses packets and counts the number of lost packets; otherwise, the data layer sends the report to the control layer.
Illustratively, the packet loss numbers of different types of messages in each time unit are counted through the process of obtaining packet loss, so as to obtain a message packet loss number table, and the message packet loss number table is stored in a database, so that the packet loss number of a certain message in a required time unit can be conveniently read subsequently.
102. And the data layer receiving control layer determines the uploading threshold of the message to be processed in the current time unit according to the packet loss number of the message to be processed and the uploading number of the message to be processed in the last time unit.
For example, the above-mentioned uploading threshold is a specific value for limiting the number of messages that can be uploaded to the control layer by the data layer in the network device.
For example, the step 102, the control layer determining, according to the packet loss number of the current packet and the uplink number of the current packet in the last time unit, the uplink threshold of the current packet in the current time unit specifically includes the following contents:
102a, substituting the packet loss number of the message to be processed and the uploading number of the message to be processed in the last time unit into an uploading threshold value calculation formula to obtain the uploading threshold value of the message to be processed in the current time unit.
Wherein, the calculation formula of the upper threshold is as follows:
u (t +1) ═ U (t) + kp e (t) + kd (e) (t) -e (t-1)) + ki (e) (t) + e (t-1)) (equation 1)
U (t) in the above formula is the number of messages to be processed in the last time unit, e (t) in the above formula is the number of packets lost in the messages to be processed in the last time unit, e (t-1) is the number of packets lost in the messages to be processed in the previous time unit of the last time unit, kp is the operator coefficient of the proportional controller, kd is the operator coefficient of the differential controller, and ki is the operator coefficient of the integral controller.
For example, the above-mentioned calculation formula of the upper threshold is obtained by an adaptive control algorithm adopted by the control layer, and the adaptive control algorithm is a control method of incremental negative feedback with adjustable parameters, and can dynamically set parameters according to the service characteristics, the actual processing capability of the network device, and the load degree of the control layer. As shown in fig. 3, a specific principle of an adaptive control algorithm of a control layer is described, in the adaptive algorithm, a packet loss number e (t) is used as an important parameter, a proportional controller, a differential controller, and an integral controller, which are obtained by a proportional control operator, a differential control operator, and an integral control operator, and U (t) allowed to be reported in a last time unit, are used to determine an uploading threshold, and a packet number U (t +1) currently required to be uploaded in a data layer is determined according to the uploading threshold, and a specific process may refer to a process shown in fig. 3.
It should be noted that the proportional controller, the derivative controller and the integral controller may be a fixed constant or a controller operation, such as integral, etc. Different manufacturers, different types of devices (e.g., a Service Router (SR), a Broadband Remote Access Server (BRAS), a Core Router (CR), a Switch (SW), etc.) may set different controllers, or different controllers may be set according to device configurations (e.g., resources such as a single-Core CPU, a multi-Core CPU, and a memory). Specifically, the proportional controller is adjusted by multiplying the packet loss number of the last time unit by a coefficient kp; the differential controller is adjusted by multiplying the difference between the number of lost packets of the previous time unit and the number of lost packets of the previous time unit by a coefficient kd; the integral controller is adjusted by multiplying a coefficient ki by the sum of the number of lost packets of the previous time unit and the number of lost packets of the previous time unit. The numerical values of the three coefficients kp, kd, and ki are set according to actual needs, and are not limited here.
103. And the data layer determines the number of the target messages uploaded in the current time unit according to the uploading threshold of the messages to be processed in the current time unit.
Illustratively, the step 103 specifically includes the following steps:
103a, when the number of the messages to be processed is smaller than the uploading threshold, the number of the target messages uploaded in the current time unit is the number of the messages to be processed.
103b, when the number of the messages to be processed is larger than the uploading threshold, the number of the target messages uploaded in the current time unit is the number of the messages to be processed corresponding to the uploading threshold, and the messages to be processed exceeding the uploading threshold are discarded.
Compared with the prior art that the number of messages sent to the control layer by the data layer is limited by setting a fixed sending threshold value, which can cause that the resources of the control layer cannot be fully utilized or the processing capacity of the control layer is too large to cause message loss, the sending threshold value in the scheme is not a fixed value, but the control layer determines the number of the messages to be sent to the data layer in an upward mode according to the packet loss number of the messages to be processed in the upward time unit of the current time unit and the sending number of the messages to be processed in the upward time unit, and the actual bearing capacity of the control layer is fully considered to determine the number of the messages to be processed which can be sent to the data layer, so that the problem that the messages are lost due to the waste of the resources of the control layer or the too. In addition, because the packet loss number corresponding to different types of messages and the number of messages uploaded in a last time unit are different, the uploading thresholds corresponding to different types of messages are also different, so that different uploading thresholds can be set according to different message types, and the scheme can adapt to application scenes of uploading various messages, thereby achieving the purpose of fully utilizing control layer resources and ensuring that services are developed in order and equipment runs stably.
