Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for processing a message.
Background
Bidirectional forwarding detection (Bidirectional Forwarding Detection, BFD) is a generic, standardized, media independent and protocol independent fast failure detection mechanism for detecting link connectivity conditions in IP networks, ensuring that communication failures can be detected quickly between network devices in order to take relevant measures in time, ensuring continued operation of the service. BFD may rapidly detect failures of bi-directional forwarding paths between two network devices for various upper layer protocols (e.g., routing protocols, etc.). The upper layer protocol typically employs a Hello message mechanism to detect faults and may provide millisecond level detection.
In the case that the network device is a routing device, thousands of BFD sessions, even tens of thousands of BFD sessions, are often maintained, and a message transmission interval of BFD messages corresponding to each BFD session is typically between 10ms and 100ms, if the BFD sessions are processed by a central processing unit (Central Processing Unit, CPU) in the routing device in a conventional manner, a large number of BFD sessions cannot be processed at a shorter message transmission interval due to limited message processing performance of the CPU.
Therefore, the CPU in the routing device generally compares the first message sending interval with the second message sending interval of the BFD message corresponding to the BFD session configured locally after obtaining the first message sending interval of the BFD message corresponding to any BFD session between the opposite-end routing device and the local-end routing device; under the condition that the comparison result is that the first message sending interval is not smaller than the second message sending interval, a corresponding network processor (Network Processor, NP) sends corresponding BFD messages to opposite-end routing equipment according to the first message sending interval; under the condition that the comparison result is that the first message sending interval is smaller than the second message sending interval, judging whether the first message sending interval is the NP-supported message sending interval in the local end routing equipment; when the judgment result is yes, the corresponding NP sends corresponding BFD messages to the opposite-end routing equipment according to the first message sending interval; and if the judgment result is negative, the CPU sends corresponding BFD messages to the opposite-end routing equipment according to the first message sending interval.
However, in the above processing manner, there still exists a phenomenon that a CPU in the routing device needs to process a large number of BFD sessions, and thus a problem that a related BFD packet is lost and a related BFD session oscillates occurs.

The embodiments of the present application will be described in detail.
The embodiment of the application provides a message processing method, which is applied to a CPU in routing equipment, as shown in figure 1, and can comprise the following steps:
s11, receiving a first BFD message of which the state of the BFD session is not ready DOWN, which is sent by opposite-end routing equipment and aims at target bidirectional forwarding detection.
In this step, the first BFD packet carries a first packet sending interval. Of course, other contents are carried in the first BFD packet, which are all of the prior art and are not listed here.
S12, if the second message sending interval of the second BFD message corresponding to the target BFD session configured locally is smaller than the first message sending interval, judging whether the first message sending interval is the NP-supported message sending interval corresponding to the target BFD session in the routing equipment; if not, executing step S13; if the determination result is yes, the conventional flow is executed, that is, steps S19 to S20 are executed.
S13, judging whether the current BFD session load value of the CPU reaches a set threshold value; if the judgment result is negative, executing the steps S14 to S15; when the determination result is yes, step S16 is performed.
In this step, the current BFD session load value is a quantity value of the third BFD packet received by the CPU within a set period of time before the first BFD packet is received.
S14, sending a second BFD message with the INIT state and carrying the first message sending interval to the opposite-end routing equipment.
And S15, when the state of the target BFD session is the UP state, sending a second BFD message which is in the UP state and carries the first message sending interval to opposite-end routing equipment according to the first message sending interval.
S16, selecting a third message sending interval meeting preset conditions from all message sending intervals supported by the NP.
In this step, the third packet transmission interval is smaller than the first packet transmission interval.
S17, generating first session information at least comprising a first message sending interval, a third message sending interval and a first session timeout time calculated based on the first message sending interval, and sending a second BFD message with the state INIT and carrying the first message sending interval to opposite-end routing equipment.
And S18, when the state of the target BFD session is the UP state, the first session information is sent to the NP so that the NP can send a second BFD message which is the UP state and carries the first message sending interval to the opposite terminal routing equipment according to the third message sending interval.
S19, generating third session information at least comprising a first message sending interval and a first session timeout time, and sending a second BFD message with the state INIT and carrying the first message sending interval to opposite-end routing equipment.
And S20, when the state of the target BFD session is the UP state, third session information is sent to the NP so that the NP can send a second BFD message which is the UP state and carries the first message sending interval to the opposite-end routing equipment according to the first message sending interval.
In step S12, the determination method of the NP corresponding to the target BFD session is a prior art, and is not described in detail herein. Here, for the NP corresponding to the target BFD session, other BFD sessions may also be corresponding.
In the step S13, the set threshold and the set duration may be set according to the actual requirement of the network where the routing device is located.
Specifically, in the above step S16, when the CPU selects the third packet transmission interval satisfying the preset condition from all the packet transmission intervals supported by the NP, the CPU may implement the following procedure:
and selecting a message transmission interval which is smaller than the first message transmission interval and has the smallest absolute value of the difference value between the first message transmission interval and the first message transmission interval from all message transmission intervals supported by the NP, and taking the message transmission interval as a third message transmission interval.
In step S17 described above, the CPU may calculate the first session timeout time in accordance with existing calculation methods. For example, the CPU calculates a first message transmission interval N times, and uses the calculated result as a first session timeout time. Here, the value of N may be set according to the actual requirement of the network where the routing device is located, for example, the value of N is 3, etc.
In addition, in the step S17, the first session information may further include the IP address of the routing device, the IP address of the opposite-end routing device, the local identifier (Local Discriminator, LD) of the target BFD session, the remote identifier (Remote Discriminator, RD) of the target BFD session, and the like, which are not listed here.
After the step of "sending the second BFD packet with the status of INIT and the first packet sending interval to the peer routing device" in step S17, the CPU performs the existing procedure until the status of the target BFD session is UP. The specific flow is as follows: the CPU receives a first BFD message which is sent by opposite terminal equipment, has INIT and carries a first message sending interval; and finally, when receiving the first BFD message which is sent by the opposite terminal equipment and is in the state of UP and carries the first message sending interval, the CPU determines that the state of the target BFD session is in the UP state.
After the CPU performs the above step S18, for the NP corresponding to the target BFD session, the CPU performs the step of sending, to the peer routing device, the second BFD packet having the UP state and carrying the first packet sending interval according to the third packet sending interval, and monitors, according to the first session timeout time included in the first session information, the first BFD packet having the UP state from the peer device.
It should be further noted that, in the embodiment of the present application, after receiving the first BFD packet, the CPU may further perform the following existing operations:
if the second message sending interval is not smaller than the first message sending interval, generating second session information at least comprising the second message sending interval and a second session timeout time calculated by the CPU based on the second message sending interval, and sending a second BFD message with INIT and carrying the second message sending interval to opposite-end routing equipment;
and when the state of the target BFD session is the UP state, sending second session information to the NP so that the NP sends a second BFD message which is in the UP state and carries the second message sending interval to the opposite-end routing equipment according to the second message sending interval.
The above message processing method is described in detail below with reference to specific embodiments.
Assume that a routing device 1 and a routing device 2 in a certain network need to establish a BFD session 1. The message sending interval 1 of the BFD message 1 corresponding to the BFD session 1 configured by the CPU2 in the routing equipment 2 is 33ms, and the message sending intervals supported by all NPs in the routing equipment 2 are 11ms, 22ms, 33ms and 44ms; the message transmission interval 2 of the BFD message 2 corresponding to the BFD session 1 configured by the CPU1 in the routing device 1 is 30ms, and all NP-supported message transmission intervals in the routing device 1 are 10ms, 20ms, 30ms, and 40ms.
Assume that CPU1 in routing device 1 receives BFD message 1 sent by routing device 2 for BFD session 1 having a state of DOWN and carrying message sending interval 1.
The CPU1 finds that the message transmission interval 2 is smaller than the message transmission interval 1, at this time, the CPU1 determines whether the message transmission interval 1 is a message transmission interval supported by NP (for example, NP 1) corresponding to the BFD session 1 in the routing apparatus 1.
Since the message sending intervals supported by NP1 are 10ms, 20ms, 30ms and 40ms, the judgment result is no, and in this case, the CPU1 further judges whether the current BFD session load value of the CPU reaches the set threshold.
Assuming that the current BFD session load value is a value of the number of BFD messages received by the CPU1 within 1 second before receiving the BFD message 1 with the state DOWN sent by the routing device 2, and assuming that the determination result is yes, at this time, the CPU1 selects, as the message transmission interval 3, a message transmission interval (i.e., 30ms, which can be understood as a message transmission interval closest to 33 ms) that is smaller than 33ms and has the smallest absolute value of the difference value from 33ms, from all message transmission intervals (i.e., 10ms, 20ms, 30ms, and 40 ms) supported by the NP 1.
Next, the CPU1 generates session information 1 including at least a message transmission interval 1 (i.e., 33 ms), a message transmission interval 3 (i.e., 30 ms), and a session timeout time 1 (e.g., 99ms,3 times the message transmission interval 1) calculated by the CPU based on the message transmission interval 1, and transmits a BFD message 2 having the state INIT and carrying the message transmission interval 1 to the routing device 2.
Finally, when the state of the BFD session 1 is UP, the CPU1 sends session information 1 to the NP1 in the routing apparatus 1, so that the NP1 sends, to the routing apparatus 2, a BFD packet 2 having UP and carrying a packet sending interval 1 (i.e., 33 ms) at a third packet sending interval 3 (i.e., 30 ms), and subsequently, if the BFD packet 1 having UP sent by the routing apparatus 2 is not received when the session timeout time 1 (i.e., 99 ms) arrives, a failure notification message is reported to the CPU 1.
As can be seen from the above technical solutions, in the embodiments of the present application, for a CPU in a routing device, when a first BFD packet sent by an opposite-end routing device and aiming at a target BFD session is received and the state of the target BFD session is DOWN and the first BFD packet carries a first packet sending interval, and the second packet sending interval of a locally configured second BFD packet corresponding to the target BFD session is smaller than the first packet sending interval, once it is determined that the first packet sending interval is not the packet sending interval supported by an NP corresponding to the target BFD session in the routing device, the CPU does not directly send the corresponding second BFD packet according to the first packet sending interval, but further determines whether the current BFD session load value of the CPU reaches a set threshold, and if the determination result is yes, the corresponding BFD packet is still sent by the corresponding NP according to the packet sending interval selected by the CPU, so that the CPU needs to process a large number of BFD sessions can be avoided, and the problem of lost packets of related BFD packets and related BFD sessions are avoided.
