Next, examples of the present application will be described in detail.

An embodiment of the present application provides a message speed limiting method, which is applied to an active main control board in a network device, and as shown in fig. 1, the method may include the following steps:

s11, acquiring the speed limit index and the speed limit value of the forwarding chip where the output interface of the target SRv6 tunnel is located.

S12, issuing the obtained speed limit index and the obtained speed limit value to all line card boards in the network equipment, so that when any line card board in the network equipment receives a first data message which needs to be forwarded by using a target SRv6 tunnel, the speed limit index is added into the first data message to obtain a second data message, an output interface of the second data message is determined, and when the determined output interface is on the line card board, according to the speed limit value corresponding to a forwarding chip where the determined output interface corresponding to the speed limit index is located, SRv6 message packaged based on the first data message obtained after deleting the speed limit index in the second data message is forwarded after speed limit processing; and when the determined output interface is not on the line card board, sending the second data message to the line card board where the determined output interface is located, and carrying out speed limit processing on the SRv6 message packaged by the first data message obtained by deleting the speed limit index in the second data message according to the speed limit value corresponding to the forwarding chip where the determined output interface corresponding to the speed limit index is located by the corresponding line card board and then forwarding the SRv6 message.

It should be noted that, for the line card board, when determining the outgoing interface of the second data message, if the outgoing interface of the target SRv6 tunnel is a physical port, it may be directly determined that the physical port is the outgoing interface of the second data message; if the egress interface of the target SRv6 tunnel is an aggregation port, it may be determined by a hashing algorithm which member port of the aggregation port the egress interface of the second data packet is.

In addition, the specific encapsulation process of the cable card board encapsulating the first data message obtained after deleting the speed limit index in the second data message into SRv6 message is the prior art, and details are not described herein.

Specifically, in step S11, the master board may obtain the speed limit index and the speed limit value of the forwarding chip on which the egress interface corresponding to the target SRv6 tunnel is located in the following manner:

when an output interface of a target SRv6 tunnel is a physical port, acquiring a speed limit value corresponding to the physical port, determining the acquired speed limit value as the speed limit value of a forwarding chip where the physical port is located, and applying for a unique speed limit index for the forwarding chip where the physical port is located from a preset speed limit index pool;

when the exit interface of the target SRv6 tunnel is an aggregation port, acquiring a speed limit value corresponding to the aggregation port, calculating the speed limit values of forwarding chips in which all member ports are located according to the bandwidth of the member ports belonging to the aggregation port on the forwarding chip in which all the member ports are located in the aggregation port, and applying for a unique speed limit index for the forwarding chips in which all the member ports are located in a preset speed limit index pool.

It should be noted that, in an example, the speed limit value of the forwarding chip where the output interface corresponding to the target SRv6 tunnel is located, which is acquired by the main control board, may be presented on a speed limit template, where different speed limit values are recorded on different speed limit templates, and the template IDs of the different speed limit templates are different. In this case, the speed limit value of the forwarding chip on which the output interface corresponding to the target SRv6 tunnel is located, which is acquired by the main control board, may be represented by a template Identifier (ID) of the speed limit template.

In addition, in the above acquisition process, the main control board may specifically calculate the speed limit values of the forwarding chips where all the member ports are located in the following manner:

aiming at each forwarding chip in the forwarding chips where all the member ports are located, performing product operation on the sum of the bandwidths of the member ports belonging to the aggregation port on the forwarding chip and the speed limit value corresponding to the aggregation port to obtain a first operation result;

summing the bandwidths of the member ports belonging to the aggregation port on the forwarding chip where all the member ports are located to obtain a second operation result;

and carrying out quotient calculation on the first calculation result and the second calculation result to obtain the speed limit value of the forwarding chip.

For example, it is assumed that the network device includes a main master control board 11, a line card board 1, a line card board 2, and a line card board 3. An outlet interface of a certain SRv6 tunnel on the network equipment is assumed to be an aggregation port 4, and a corresponding speed limit value is A; the aggregation port 4 has 4 member ports, namely a member port 41, a member port 42, a member port 43 and a member port 44; assuming that the member port 41 and the member port 42 are both on the forwarding chip 21 on the cable card board 2 in the network device, the bandwidth of the member port 41 is B, and the bandwidth of the member port 42 is C; assuming that the member port 43 is on the forwarding chip 22 on the cable card board 2 in the network device, the bandwidth of the member port 43 is D; assume that the member port 44 is on the forwarding chip 31 of the cable card board 3 in the network device, and the bandwidth of the member port 44 is E.

Then, the forwarding chips where the egress interfaces of the SRv6 tunnel are located are the forwarding chip 21, the forwarding chip 22, and the forwarding chip 31. The main control board 11 can calculate the speed limit value of the forwarding chip 21 as

The main control board 11 can calculate the speed limit value of the forwarding chip 22 as

The main control board 11 can calculate the speed limit value of the forwarding chip 31 as

It should be further noted that, in order to ensure that the network device can normally operate when the main control board fails, after the main control board obtains the speed limit index and the speed limit value of the forwarding chip where the output interface of the target SRv6 tunnel is located, the main control board may also synchronize the obtained speed limit index and the obtained speed limit value of the forwarding chip where the output interface of the target SRv6 tunnel is located with the standby main control board in the network device, so as to be conveniently used when the main control board fails.

The embodiment of the application provides a message speed limiting method, which is applied to any line card board in network equipment, and as shown in fig. 2, the method can include the following steps:

and S21, receiving a speed limit index and a speed limit value of a forwarding chip where an output interface of the target SRv6 tunnel is located, which are obtained by the master control board sent by the master control board in the network device.

S22, when the first data message is received and the target SRv6 tunnel is needed to be used for forwarding the first data message, adding the speed limit index into the first data message to obtain a second data message, and determining an output interface of the second data message;

s23, judging whether the determined outlet interface is on the cable clamping board; if the determination result is yes, step S24 is executed, and if the determination result is no, step S25 is executed.

And S24, according to the speed limit value corresponding to the determined forwarding chip where the output interface is located and corresponding to the speed limit index, performing speed limit processing on the SRv6 message packaged based on the first data message obtained after deleting the speed limit index in the second data message, and then forwarding the message.

And S25, sending the second data message to the line card board where the determined outlet interface is located, so that the corresponding line card board performs speed limit processing on the SRv6 message packaged by the first data message obtained by deleting the speed limit index in the second data message according to the speed limit value corresponding to the forwarding chip where the determined outlet interface is located and corresponding to the speed limit index, and then forwards the message.

It should be noted that, for the line card board, how to determine the outgoing interface of the second data message and how to encapsulate the first data message obtained after deleting the speed limit index in the second data message into SRv6 messages is described when the master board side describes the message speed limit method, and details are not described here.

In addition, for the main master control board, how to obtain the speed limit index and the speed limit value of the forwarding chip where the egress interface of the target SRv6 tunnel is located has also been described when the message speed limit method is described on the main master control board side, and details are not described here.

It can be seen from the above technical solutions that, in the embodiment of the present application, a message speed limit flow is added in the process of forwarding a data message using an SRv6 tunnel, and the specific flow is as follows:

firstly, a main control board in the network equipment acquires a speed limit index and a speed limit value of a forwarding chip where an output interface of a target SRv6 tunnel is located, and transmits the acquired speed limit index and speed limit value to all line card boards in the network equipment; then, when any line card board in the network equipment receives a first data message which needs to be forwarded by using a target SRv6 tunnel, adding a speed limit index into the first data message to obtain a second data message, determining an output interface of the second data message, and when the determined output interface is on the line card board, carrying out speed limit processing on a SRv6 message encapsulated on the basis of the first data message obtained by deleting the speed limit index in the second data message according to a speed limit value corresponding to a forwarding chip where the determined output interface is located and corresponding to the speed limit index, and then forwarding the SRv6 message; and when the determined output interface is not on the line card board, sending the second data message to the line card board where the determined output interface is located, and carrying out speed limit processing on the SRv6 message packaged by the first data message obtained by deleting the speed limit index in the second data message according to the speed limit value corresponding to the forwarding chip where the determined output interface corresponding to the speed limit index is located by the corresponding line card board and then forwarding the SRv6 message.

Therefore, the problem of network congestion can be avoided to a certain extent through the message speed-limiting flow, and network experience is improved.
