Description
Technical Field
The invention relates to the technical field of network equipment, in particular to a protocol high-availability protection system and a protection method.
Background
With the increasing network bandwidth, the demand of customers for high availability of control planes in network devices, especially network devices, is higher. Each oscillation and re-convergence of the control plane will cause network outage and looping before convergence is completed. The high-availability protection of the control plane means that main/standby switching is performed in a main control unit of the equipment, a protocol is kept uninterrupted, the condition that the flow forwarding of a forwarding plane is influenced by the oscillation and the re-convergence of the control plane is avoided, and the network service quality is improved.
There are several ways to achieve the high availability of the protocol:
1. each protocol of the control plane realizes the synchronization and switching protection of the main and standby states, and the method has high complexity and lacks the uniformity and the simplicity of the scheme.
2. The high availability protection of the control plane is achieved by means of a high availability database. The implementation of the database can be further subdivided into two ways:
(1) The weak consistency scheme of the main and standby main control units of the database can ensure the final consistency between the main and standby units, but the consistency is lack of strict guarantee. After the main control unit modifies the data, the data is synchronized to the front of the standby main control unit, and the data between the main control unit and the standby main control unit is inconsistent. The main/standby switching is initiated within this period of time, which will cause the function of the protocol to fail, thereby causing the oscillation and re-convergence of the control plane. All such schemes based on weak consistency have a limited range of application. Only high availability based on soft state protocols can be supported.
(2) The method for realizing the strong consistency is to adopt a blocking type synchronous copy mode, that is, after the content of the database is modified on the main control unit, the content must be synchronized to one or more protection nodes, and after response confirmation, the modification action can be successfully returned. This approach ensures strong consistency between the primary and standby master control units, but each modification involves data synchronization and waiting across nodes, which can lead to severe performance degradation of the database.
Therefore, how to ensure the high availability of the network protocol when the main control unit and the standby control unit are switched becomes a problem to be solved urgently.

However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a protocol high availability protection system, the specific structure of which is shown in fig. 1, and the protocol high availability protection system comprises: a first main control unit 10 and a second main control unit 20 connected with the first main control unit 10; the first main control unit 10 is configured to receive a message signal sent by another system, after receiving the message signal, the first main control unit 10 processes the message signal and obtains processing data, and then stores the obtained processing data in the first main control unit 10 and the second main control unit 20; after the second main control unit 20 obtains the processing data of the message signal, the first main control unit 10 sends a message reception confirmation signal to other systems. In addition, the line card unit 30 is connected to the first main control module 10, the line card unit 30 is connected to the second main control module 20, and the line card unit 30 is configured to receive the processing data and forward traffic according to the processing data.
Compared with the prior art, after the first main control unit 10 receives and processes the message signals sent by other systems, the processing data obtained by processing the message signals is stored in the first main control unit 10 and simultaneously synchronously stored in the second main control unit 20, and after the second main control unit 20 obtains the processing data, a message receiving confirmation signal is sent to other systems, so that the synchronization of the processing data of the message signals of the first main control unit 10 and the second main control unit 20 is realized, when the second main control unit 20 does not obtain the processing data of the message signals, if the main control units are switched, the first main control unit 10 is converted into the second main control unit 20, because the message receiving confirmation signal is not sent yet, other systems can resend the message signals, and the second main control unit 20 can also resend the message signals and process the message signals without reconvergence; after the second main control unit 20 obtains the processing data of the message signal, if the main control unit is switched, the first main control unit 10 is converted into the second main control unit 20, because the second main control unit 20 has stored the processing data of the message signal synchronously, the second main control unit 20 can continue to process the message signal according to the processing data of the message signal synchronously stored, and the re-convergence of the main control unit does not occur, thereby realizing the high availability of the protocol.
Specifically, as shown in fig. 2, the first master control unit 10 includes a first protocol component 11 and a first database 12 communicatively connected to the first protocol component 11, and the second master control unit 20 includes a second protocol component 21 and a second database 22 communicatively connected to the second protocol component 21. The first protocol component 11 is configured to receive a message signal, process the message signal to obtain processing data, store the processing data in the first database 12, and synchronously store the processing data in the second database 22; when a handover of the first master unit 10 and the second master unit 20 occurs, the second protocol component 21 may retrieve the stored processing data from the second database 22.
In addition, in the present application, the first database 12 includes a first sending module 13, and the first sending module 13 is configured to store and send a message reception confirmation signal to other systems. After the first protocol component 11 receives foreign language signals of other systems, a message reception confirmation signal is generated and stored in the first sending module 13, after the second main control unit 20 acquires processing data, the first sending module 13 sends the stored message reception confirmation signal to other systems, after the other systems receive the message reception confirmation signal, the sent message signal is not sent any more, if the second main control unit 20 does not acquire the processing data yet and the first main control unit 10 and the second main control unit 20 are switched, the message reception confirmation signal is stored in the first sending module 13 and is not sent yet, after the other systems do not receive the message reception confirmation signal after a period of time interval, the message signal is retransmitted, and at this time, the message signal can be received and reprocessed by the second protocol component 21 in the second main control unit 20, so that processing loss of the message signal is avoided, and the main control unit does not reconvergence, thereby realizing high availability of the protocol.
Specifically, in the present embodiment, the first database 12 is communicatively connected to the second database 22, and the first database 12 is configured to receive the processing data from the first protocol component 11 and transmit the processing data to the second database 22. The processed data is transmitted to the second database 22 through the first database 12, when the processed data needs to be compressed or stored after being processed in other manners in the storage process, the first database 12 can directly transmit the processed data to the second database 22, and the second database 22 can directly store the processed data without processing the processed data, so that the transmission and storage efficiency of the processed data is effectively improved. It should be understood that the foregoing transmission of the processing data to the second database 22 through the first database 12 is only an example in this embodiment, and is not limited thereto, and in other embodiments of the present invention, other manners such as transmission of the processing data to the first database 12 and the second database 22 through the first protocol component 11 may also be used, and the configuration may be flexibly set according to actual needs.
In addition, the second database 22 includes a second transmitting module 23, and the second transmitting module 23 is configured to transmit a processed data reception confirmation signal to the first database 12 after the second database 22 receives the processed data; after the first database 12 receives the processed data receiving confirmation signal, the first sending module 13 sends the stored message receiving confirmation signal to other systems. The second sending module 23 is configured to send a processed data receiving confirmation signal to the first database 12, so as to ensure that the second database 22 has received the processed data of the message signal when the first sending module 13 sends the stored message receiving confirmation signal to another system, thereby ensuring that the data of the first database 12 and the second database 22 are synchronized.
Preferably, in the present embodiment, the network Protocol run by the First Protocol component 11 is the same as the network Protocol run by the second Protocol component 21, for example, the First Protocol component 11 and the second Protocol component 21 may run a network communication Protocol such as TCP (Transmission Control Protocol) or OSPF (Open Shortest Path First). When the first main control unit 10 and the second main control unit 20 are switched, the network protocol run by the first protocol component 11 is the same as the network protocol run by the second protocol component 21, which can ensure the continuous processing of the message signal, thereby further realizing the high availability of the protocol.
Preferably, in this embodiment, the first database and the second database are both SDDMs (Shared-Memory Distributed Data Manager). The SDDM is a distributed data storage system based on a shared memory, and the system can provide extremely high read-write performance through the shared memory, simultaneously ensure data synchronization, time sequence linkage and time sequence cooperation between a first database and a second database, and ensure strict consistency of information between the first database and the second database.
A second embodiment of the present invention provides a protocol high availability protection method, which is applied to a protocol high availability protection system including a first main control unit and a second main control unit, and as shown in fig. 2, the method includes the following steps:
step S101: the first main control unit receives message signals sent by other systems.
Specifically, in this embodiment, the other system may be another system operating on a terminal different from the protocol high availability protection system, or another system operating on the same terminal as the protocol high availability protection system, and may be flexibly set according to actual needs. For example, when the network protocol running in the first main control unit is a TCP protocol, the other system may be a client of the current terminal; when the network protocol running in the first master control unit is the OSPF protocol, the other system may be an LSA advertisement network topology running on the other terminal.
Step S102: the first main control unit processes the message signal to acquire processing data.
Specifically, in this embodiment, the first main control unit processes the received message signal through the network protocol operated by the first main control unit, and during the protocol processing, corresponding processing data, such as change data of the protocol state and the like, may be generated, where the change data of the protocol state includes state data required by the protocol itself for processing, and also includes a forwarding information entry calculated according to the protocol message and used for guiding the forwarding plane to work.
Step S103: the first master control unit stores the processing data to the first master control unit and the second master control unit.
Step S104: and the first main control unit sends message receiving confirmation signals to other systems after the second main control unit acquires the processing data.
Specifically, in this embodiment, after the second main control unit obtains the processed data, the second main control unit generates and sends a processed data reception confirmation signal to the first main control unit, and after the first main control unit receives the processed data reception confirmation signal sent by the second main control unit, the step of sending a message reception confirmation signal to another system is executed, so as to ensure synchronization of the processed data between the first main control unit and the second main control unit.
Step S105: and the first main control unit or the second main control unit sends processing data to the line card unit.
Specifically, in this embodiment, after sending a message reception acknowledgement signal to another system, the first main control unit sends the processing data to the line card unit, and the line card unit performs traffic forwarding according to the processing data.
It should be noted that, in this embodiment, as long as the first main control unit completes processing of one message signal, all processing data of the message signal is obtained, and whether the processing data and the second main control unit complete synchronous storage or not, the second main control unit may continue to receive another message signal for processing, so as to ensure that no fault occurs in the processing process of the message signal, and improve the processing efficiency of the message.
It should be understood that this embodiment is an example of a protocol highly available protection method corresponding to the first embodiment, and this embodiment may be implemented in cooperation with the first embodiment. The related technical details and technical effects mentioned in the first embodiment are still valid in this embodiment, and are not described herein again in order to reduce repetition. Accordingly, the related technical details and technical effects mentioned in the present embodiment can also be applied to the first embodiment.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the steps contain the same logical relationship, which is within the protection scope of the present patent; it is within the scope of this patent to add insignificant modifications or introduce insignificant designs to the algorithms or processes, but not to change the core designs of the algorithms and processes.
In the following, the network protocols run in the first protocol component and the second protocol component will be exemplified, specifically as follows.
When the network protocol running in the first protocol component and the second protocol component is TCP, TCP is a network transport layer protocol that enables reliable transmission of information over a network through a send-acknowledge-sliding window mechanism. Reliable transmission of TCP is divided into two directions, sending and receiving, which are described as follows:
the TCP sending process is shown in fig. 3, and includes:
step S201: the first protocol assembly receives a message signal sent by a client.
Step S202: the first protocol assembly processes the message signal to obtain the content of the sending window, and stores the content of the sending window in the first database.
Step S203: the first protocol assembly generates a message receiving confirmation signal and stores the message receiving confirmation signal in the first message sending module.
Step S204: the first database synchronizes the contents of the send window to the second database.
Step S205: and after receiving the contents of the sending window, the second database stores the contents of the sending window and sends a data receiving confirmation signal for processing to the first database through the second sending module.
Step S206: after the first database receives the processed data receiving confirmation signal, the first message sending module sends the stored message receiving confirmation signal to the client.
Step S207: the first protocol component transmits the contents of the transmission window stored in the first database to the line card unit.
Step S208: and after receiving the content of the sending window, the line card unit sends a response message to the first protocol component.
Step S209: and the first protocol component updates the content of the sending window stored in the first database according to the response message.
Step S210: the first database synchronizes the updated contents of the send window to the second database.
Therefore, in the process, the conversion main control unit can ensure that the TCP link is not interrupted and information is not lost at any time. If the master control unit is converted before step S206, the first sending module does not send the stored message receiving confirmation signal to the client, and the client will send the message signal to the converted master control module again if the client does not receive the message receiving confirmation signal for a certain time; if the main control unit is switched after step S206, the sliding window information is already synchronized to the second database, and the second protocol component in the second main control module after switching can acquire the contents of the sending window from the second database and continue processing, thereby ensuring the reliability of TCP transmission.
The TCP receiving process is shown in fig. 4, and includes:
step S301: the first protocol assembly receives a message signal sent by an external terminal.
Step S302: the first protocol assembly processes the message signal to obtain the content of the sending window, and stores the content of the sending window in the first database.
Step S303: the first protocol assembly generates a message receiving confirmation signal and stores the message receiving confirmation signal in the first message sending module.
Step S304: the first database synchronizes the send window content to the second database.
Step S305: and after receiving the contents of the sending window, the second database stores the contents of the sending window and sends a data receiving confirmation signal for processing to the first database through the second sending module.
Step S306: after the first database receives the processed data receiving confirmation signal, the first message sending module sends the stored message receiving confirmation signal to the client.
Step S307: the first protocol component transmits the contents of the transmission window stored in the first database to the line card unit.
Therefore, in the process, the conversion main control unit can ensure that the TCP link is not interrupted and information is not lost at any time. If the main control unit is converted before step S307, the first sending module does not send the stored message reception confirmation signal to the external terminal, and the external terminal sends the message signal to the converted main control module again if the external terminal does not receive the message reception confirmation signal for a certain time. Therefore, the reliability of TCP transmission in the conversion process of the main control module is ensured.
When the network protocol operated in the first protocol component and the second protocol component is the OSPF protocol, the OSPF protocol is an IP network routing protocol, and the protocol collects and advertises the network topology through the LSA, and calculates a route according to the network topology, so as to guide the forwarding engine to send the traffic. The specific steps are shown in fig. 5, and include:
step S401: the external terminal sends a message signal including the network topology to the first protocol component through the LSA, and the first protocol component receives the LSA.
Step S402: the first protocol component stores the LSA information into a first database, simultaneously starts Shortest Path First (SPF) routing calculation, and stores the calculated routing information into the first database.
Step S403: the first protocol assembly generates a message receiving confirmation signal and stores the message receiving confirmation signal in the first message sending module.
Step S404: the first database synchronizes the LSA information and the routing information to the second database.
Step S405: after receiving the LSA information and the routing information, the second database stores the LSA information and the routing information, and sends a data receiving and confirming signal for processing to the first database through the second sending module.
Step S406: after the first database receives the processed data receiving confirmation signal, the first message sending module sends the stored message receiving confirmation signal to the client.
Step S407: the first protocol component transmits the contents of the transmission window stored in the first database to the line card unit.
Therefore, in the process, the switching main control unit can ensure that the routing information in the OSPF is not lost at any time. If the main control unit is converted before step S407, the first sending module does not send the stored message reception confirmation signal to the external terminal, and the external terminal will send a message signal to the converted main control module again if it does not receive the message reception confirmation signal for a certain time. Therefore, the reliability of OSPF transmission in the conversion process of the main control module is ensured.
It should be noted that each module referred to in this embodiment is a logical module, and in practical applications, one logical unit may be one physical unit, may be a part of one physical unit, and may be implemented by a combination of multiple physical units.
