Since the running speed of the cache is much faster than that of the memory, the function of the cache is to help the processing unit 112 run faster.

The memory (memory) 120 can provide a running space for the processes in the computer device 100. For example, the memory 120 stores a computer program (specifically, the code of the program) for generating the process. After the computer program is run by the processor to generate a process, the processor allocates a corresponding storage space for the process in the memory 120. Further, the aforementioned storage space further includes a text segment, an initialization data segment, a bit initialization data segment, a stack segment, a heap segment, and so on. The memory 120 stores data generated during the running of the process, such as intermediate data, or process data, in the storage space corresponding to the above process.

Optionally, the memory is also referred to as internal memory, and its function is to temporarily store operational data in the processor 110 and data exchanged with an external memory such as a hard disk. As long as the computer is running, the processor 110 transfers the data to be calculated into the memory for calculation, and the processing unit 112 transmits the result after the calculation is completed.

As an example and not a limitation, in the embodiment of the present application, the memory 120 is a volatile memory or a non-volatile memory, or may include both volatile and non-volatile memory. Among them, non-volatile memory is read-only memory (ROM), programmable read-only memory (programmable ROM, PROM), erasable programmable read-only memory (erasable PROM, EPROM), and electrically erasable Except for programmable read-only memory (electrically EPROM, EEPROM) or flash memory. Volatile memory is random access memory (RAM), which is used as an external cache. By way of exemplary but not restrictive description, many forms of RAM are available, such as static random access memory (static RAM, SRAM), dynamic random access memory (dynamic RAM, DRAM), and synchronous dynamic random access memory (synchronous DRAM, SDRAM), double data rate synchronous dynamic random access memory (double data rate SDRAM, DDR SDRAM), enhanced synchronous dynamic random access memory (enhanced SDRAM, ESDRAM), synchronous connection dynamic random access memory (synchlink DRAM, SLDRAM) ) And direct memory bus random access memory (direct rambus RAM, DR RAM). It should be noted that the memory 120 of the systems and methods described herein is intended to include, but is not limited to, these and any other suitable types of memory.

It should be understood that the structure of the computer device 100 listed above is only an exemplary description, and the present application is not limited thereto. The computer device 100 in the embodiment of the present application includes various hardware in a computer system in the prior art, for example, a computer device. 100 also includes other storage than the memory 120, for example, a disk storage and the like.

To facilitate understanding, the following first introduces related terms and concepts that may be involved in the embodiments of the present application.

1. Box-based router

The frame-type router includes a main control board, a switch fabric unit (SFU), and a line processing unit (LPU). Among them, SFU is the switching network version, which has the switching function. The LPU is the interface board, which has service processing and forwarding functions. The main control board is mainly responsible for the control and management of the system, for example, the out-of-band channel management SFU and LPU.

It should be understood that the out-of-band channel is a new network created by the local area network switch (LAN switch) module integrated on the main control board to control signal flow (for example, signaling signal flow, operation and maintenance signal flow, and clock signal flow). ) Will perform out-of-band management on the SFU and LPU through the out-of-band channel.

It should also be understood that the LAN switch module is a module with the function of a local area network switch.

2. Line card box

The line card box mainly undertakes the switching function in the network, which is similar to the switching processing unit SFU in the frame-based router, which has the switching function.

3. Exchange box

The switch box is mainly responsible for service processing and forwarding in the network, similar to the line processing unit LPU in the frame-based router, with service processing and forwarding functions.

It should be understood that the network formed between the line card box and the switch box can be used for data packet transmission. Specifically, the data packet of one switch box can be transmitted to other switch boxes through one or more line card boxes in the network. The data may be a message on the data plane, or may also be a control message on the management plane, which is not specifically limited in this application.

4. Control server

Responsible for the management and control of the line card box and the switch box, which is equivalent to the role of the main control board in the frame router.

The management functions of the control server can include, but are not limited to, one or more of the following: the online and offline of devices in the system, the power-on and power-off of boards, the opening and closing of ports, the management of software versions and software revisions of all boards in the system distribution.

The control function of the control server can include, but is not limited to, one or more of the following: provide a unified configuration interface, send configuration to each device in the system, save and restore configuration, run various communication protocols, and produce items under the table Send to each device of the system to control the forwarding behavior of the entire system.

5. Control messages

The message used to manage and control the entire router system is different from the data forwarded by the router. For example: devices in the system go online and offline, notify the messages generated by the management and control server, and the management server manages the messages generated by the devices in the system; the management and control server compares the software version of each device in the system, and distributes the data generated by the software version; the management server downloads The configuration data sent, the entry data generated by the communication protocol.

6. Control chip

The line card box and the switch box contain two parts of the chip, one is the hard forwarding chip, and the other is the management and control chip. In the embodiments of the present application, the management and control chip may also be referred to as a control chip.

7. In-band transmission

Control messages are generally not transmitted through the data plane network, but a new set of separate network transmission, which is out-of-band transmission; control messages are sent from the control server to the control chip, directly using the data plane network, called in-band transmission .

8. Time stamp synchronization

That is, time synchronization, the in-band network composed of line card boxes and switching boxes, in order to support more even load sharing, data packets will be fragmented and reorganized during transmission, fragment generation will carry a generation time, and the intermediate network will be based on the distribution. The time carried by the fragments is sorted to reduce the difficulty of fragment reorganization. This requires that the time of the equipment in the scale-out system is synchronized. If the time is not synchronized, fragmentation and reorganization will not be supported, and the data plane cannot be connected. The in-band transmission of control messages is to send data packets that do not need to be fragmented to avoid fragmentation and recombination, so that part of the control information can be transmitted in the in-band channel.

9. Box architecture router

The box architecture router may be, for example, a scale out switching network that is uniformly controlled by a management and control server, or may be referred to as a scale out router for short.

It should be understood that a scale out router is a router system composed of a scale out architecture network and the aforementioned management and control server. Among them, the scale-out architecture network includes the above-mentioned line card box and the above-mentioned switch box.

It should also be understood that the management and control server may be implemented by a certain server, or may also be implemented by any one of an exchange box or a line card box, which is not limited in this application. Specifically, taking the control server implemented by any one of the switch box or the line card box as an example, the control server may be located on the central processing unit (CPU) of the switch box or on the CPU of the line card box.

It should be noted that the management and control server can also be referred to as a server for short. The server in the following is the management and control server, which is mainly responsible for the control and management of the entire scale out router system.

Fig. 2 is a schematic block diagram of a possible scale-out router provided by an embodiment of the present application. As shown in FIG. 2, the scale out router includes a plurality of switching boxes 210, a plurality of line card boxes 220, and a management and control server 230.

Among them, the multiple line card boxes 220 are connected by a switch box 210. Specifically, the multiple line card boxes 220 may be connected by a data plane connection 240 between the boxes. The management and control server 230 is connected to the line card box 220, and is connected through the panel port connection 250 of the line card box 220.

It should be understood that the line card boxes 220 are not directly connected to each other, the exchange boxes 210 are not directly connected to each other, and the control server 230 is not directly connected to all boxes.

In related technical solutions, in the scale out router, the management and control server needs to be responsible for the management and control of the entire system. Since the management and control server 230 is not directly connected to all boxes, an additional switch is deployed in this solution. The switch implements the management and control server and each box (for example, multiple switch boxes 210 and multiple A line card box 220) is directly connected. The newly built network provides an out-of-band channel for the communication between the management and control server and each box. The management and control server can perform out-of-band management and control of each box through the out-of-band channel.

The embodiment of the application provides a data transmission method. In a scale out router system, the management and control server can directly send management and control messages to each box through the in-band channel formed by the port on the box panel to achieve in-band management and control communication. There is no need to build and maintain an additional external network to send management and control messages, which can reduce the cost and complexity of construction and maintenance.

The following describes in detail a data transmission method provided by an embodiment of the present application with reference to FIG. 3. The method is applied to a scale out switching network that is uniformly controlled by a management and control server, and is executed by the above-mentioned computer equipment. As shown in Fig. 3, the method may include steps 310-330, and steps 310-330 will be described in detail below.

Step 310: The first box receives the first management and control message sent by the management and control server.

In the embodiment of the present application, the management and control server is mainly responsible for the control and management of the entire scale out router system, and the first management and control message is a message sent when the management and control server manages and controls the second box. For example, responsible for the software version management, configuration management, equipment management, control protocol, etc. of the entire system. As an example, the management and control server needs to manage and control the second box, and it can send the first management and control message to the second box. The first management and control message sent by the management and control server to the second box is used to manage and control the second box.

As an example, the first management control message in this application may include, but is not limited to, one or more of the following: software version message, resource configuration message, service configuration message, device management message, and table entry message.

It should be understood that the first management and control message sent by the management and control server to the second box needs to be sent to the control chip of the second box, and the control chip of the second box performs specific management and control actions.

Specifically, if the second box is not directly connected to the management and control server, in the embodiment of the present application, the management and control server wants to send the first management and control message to the second box, and it needs to select a proxy box. When the control server sends the first control message to the second box that is not directly connected to it, it can first send it to the proxy box, and the proxy box forwards it to the second box. It should be understood that if the first box is used as a proxy box, the second box can be used as a non-proxy box.

It should be understood that, in the embodiment of the present application, the proxy box can directly send management and control messages with the management and control server, while the non-agent box and the management and control server cannot directly send management and control messages. If a non-agent box needs to send a control message to the control server, or the control server needs to send a control message to a non-agent box, it can be sent to the agent box first, and the agent box forwards it to the non-agent box or to the control server.

It should also be understood that the foregoing management and control message may be a non-fragmented message. In the Internet protocol, when a data packet is larger than the maximum transmission unit of the link, the data packet can be broken down into many small enough fragments so as to be able to be transmitted on the link. However, the management and control message in this application may be a non-fragmented message, and the management and control message does not need to be decomposed into many small enough fragments to be transmitted on the link.

In other words, before the time stamp synchronization, the above-mentioned management and control message may be a non-fragmented message. After the time stamp is synchronized, the management and control message may be a fragmented message. For the specific method of time stamp synchronization, please refer to the description below, which will not be detailed here.

In this application, the first box directly connected to the control server is selected as the proxy box, and the first box is responsible for receiving the first control message sent by the control server to the second box through the panel port, for example, the connection 250 in FIG. And it is sent to the second box through the channel to the second box (also called a scale out switching network).

It should be understood that the above-mentioned first box and the second box may be the line card box 220. For the specific description of the line card box, please refer to the above description, which will not be repeated here.

Step 320: The first box determines that the first management and control message is sent to the second box.

After the first box receives the first management and control message sent by the management and control server, it needs to determine which box the first management and control message is sent to. Specifically, the first management and control message may include the information of the second box, and the first box may determine that the first management and control message is sent to the second box according to the information of the second box.

There are several ways of implementation. In a possible implementation way, the first management and control message includes an identifier of the second box, and the first box can determine based on the identifier that the first management and control message is sent to the second box. In another possible implementation manner, the first management and control message also includes information about the control chip in the second box, and the first box can determine that the first management and control message is sent to the second box based on the information about the control chip in the second box. of.

As an example, the information of the control chip in this application includes the Internet Protocol IP address of the control chip in the second box and/or the port number of the control chip.

It should be understood that the second box may include multiple chips. The control chip is a chip responsible for management and control. The second box is managed and controlled.

Step 330: The first box sends the first management and control message to the second box according to the first forwarding entry.

The first forwarding entry includes an identifier of the second box, information of a control chip in the second box, and a port number for the first box to send the first management control message to the second box.

The first box determines that the first control message is sent by the control server to the second box. The first box can send the first box to the second box through the first box in the first forwarding entry. The port number of the control message, the first control message is sent to the control chip in the second box.

Optionally, before step 330, the first box may also establish the first forwarding entry. Specifically, the first box may receive the first message sent by the second box, and the first message includes the identifier of the second box and the information of the control chip in the second box. The first box can establish a first forwarding entry according to the received first message, and the first forwarding entry can also be referred to as forwarding information.

It should be noted that, in this embodiment of the application, the first box serves as a proxy box. On the one hand, the management and control server can send the management and control messages sent to other boxes to the first box as the proxy box through the panel port, and the first box forwards it to the other boxes through the scale out switching network. On the other hand, other boxes, such as the second box, need to send a second control message to the control server. The second box can be sent to the first box of the proxy box through the scale out switching network, and the first box will transfer the message through the panel port. The second management and control message is sent to the management and control server.

It should be understood that the second management and control message is a non-fragmented message sent by the control chip in the second box to the management and control server. The second management and control message includes one or more of the following: hardware messages, software messages, and protocol messages, where the hardware messages include: hardware information and hardware status reported by the second box to the management and control server Information, the hardware information includes the model of the control chip in the second box information, the number of interfaces in the second box, the hardware status information includes faulty interface information on the second box, and the protocol message includes The protocol used by the second box to send the second management control message.

Specifically, take the second box sending the second management and control message to the management and control server as an example. The second box needs to establish a second forwarding entry (also called proxy information), and send the second management and control message to the first box according to the proxy information. It should be understood that the proxy information includes the identification ID of the proxy box (for example, the first box), the Internet Protocol IP address and/or the media access control MAC address of the management and control server, and the destination IP address and/or of the second management and control message The destination MAC address is the IP address and/or MAC address of the management and control server.

It should be understood that in the embodiment of the present application, in one implementation, the above-mentioned second management and control message is used to send some status information of the device to the management and control server. In another implementation, the above-mentioned second management and control message is used to send to the management and control server. Control response message. The second management and control message may include, but is not limited to: the version of the device, the interface information on the device (for example, the state of the interface and the number of interfaces), and the chip information on the device (for example, the number of chips and the version of the chip).

Optionally, before the second box establishes proxy information, the second box will also receive a second message sent by the first box. The second message includes the IP address and/or MAC address of the management and control server and indication information. The instruction information indicates that the first box is a proxy box. The second box establishes proxy information according to the second message, and when sending the second control message to the control server, it can determine the destination IP address and/or of the second control message according to the IP address and/or MAC address of the control server in the proxy information Destination MAC address, and according to the identification ID of the agent box (for example, the first box) in the agent information, send the second control message to the agent box (for example, the first box).

In the above technical solution, when other boxes need to send management and control messages to the management and control server, they can send the management and control messages to the agent box first. In this way, even if the management and control server is not online, it will not affect the startup and work of the entire scale out router system. , Improve the work efficiency of scale-out routers.

The specific implementation process of a data transmission method according to an embodiment of the present application will be described in detail below with reference to FIG. 4. It should be noted that the example in FIG. 4 is only to help those skilled in the art understand the embodiments of the present application, and is not intended to limit the application embodiments to the specific values or specific scenarios illustrated in FIG. 4. Those skilled in the art can obviously make various equivalent modifications or changes based on the example given in FIG. 4, and such modifications and changes also fall within the scope of the embodiments of the present application.

FIG. 4 is a schematic flowchart of another data transmission method provided by an embodiment of the present application. The method shown in FIG. 4 may include steps 410-420, and steps 410-420 will be described in detail below.

It should be understood that, for ease of description, the line card box is taken as an example for description in FIG. 4.

Step 410: After the new line card box is online, open the channel from the newly online line card box to other online line card boxes.

When a new line card box is launched in the scale out router system, in-band broadcast announcements and unicast responses are used to open the channel from the new line card box to other line card boxes.

As an example, take Fig. 5 as an example to illustrate the process of opening a channel from a new line card box to other line card boxes.

It should be understood that the newly launched line card box may also be referred to as the new line card box for short. For ease of description, the new line card box is used for description below.

1. After the new line card box 2 is connected to the system, it broadcasts the information of the new line card box 2 to other online line card boxes.

After the new line card box 2 is connected to the system, the unicast channel between it and other online line card boxes (for example, line card box 0 and line card box 1) has not been opened yet. The new line card box 2 can send broadcast messages to other online line card boxes (for example, line card box 0 and line card box 1) through the in-band switching network. The broadcast message includes the information of the new line card box 2.

It should be noted that the in-band switching network may be a network composed of multiple switching boxes, and each line card box is connected or communicating through the in-band switching network.

The information of the new line card box 2 may be one or more of the following: the identity (ID) port number of the new line card box 2.

In some embodiments, the new line card box 2 may be a switching network interface card (FIC) ID. It should be understood that the FIC ID is the identification of the new line card box 2 in the in-band switching network.

In the embodiment of the present application, the broadcast message may be, for example, a broadcast heartbeat message. The new line card box 2 broadcasts the information of the new line card box 2 to other online line card boxes through a heartbeat message.

2. Open the unicast channel between other online card boxes and the new line card box 2.

After other online line card boxes (for example, line card box 0 and line card box 1) receive the information broadcast by the new line card box 2, the information of the new line card box 2 is recorded locally and opened with the new line card Unicast channel between box 2.

Take line card box 0 as an example. After line card box 0 receives the information broadcast by new line card box 2, it can open the corresponding unicast channel according to the ID and/or port number of new line card box 2, and open line card box 0 and new line card box. Unicast channel between line card box 2 (0->2).

It should be understood that in the embodiment of the present application, the line card box 0 can also initialize the unicast channel (0->2) between the line card box 0 and the new line card box 2. For example, the line card box can perform unicast queues. Some other settings, for example, setting some parameters of the queue, recording some related information (for example, the FIC ID received from which channel), etc.

Similarly, the online line card box 1 can also open the unicast channel (1->2) between the line card box 1 and the new line card box 2 according to the above method. For details, please refer to the above description, here No longer.

3. Other online line card boxes send unicast response information to the new line card box 2.

Other online line card boxes (for example, line card box 0 and line card box 1) can also send unicasts to new line card box 2 after opening the unicast channels between them and new line card box 2 respectively. Response information.

Take line card box 0 as an example. After line card box 0 opens the unicast channel (0->2) between it and new line card box 2, it sends a unicast response message to new line card box 2. The unicast response message includes line card box 0 ID, port number (port number).

Similarly, the online line card box 1 can also send a unicast response message to the new line card box 2. For details, please refer to the above description, which will not be repeated here.

In the embodiment of the present application, the unicast response message may be, for example, a unicast heartbeat confirmation message.

4. After the new line card box 2 receives the unicast response message sent by other online line card boxes, it opens the unicast channel between it and other online line card boxes.

After the new line card box 2 receives the unicast response message sent by other online line card boxes, it opens the line between it and other online line card boxes according to the ID and port number of the line card box in the unicast response message Unicast channel.

Take the new line card box 2 receiving the unicast response message sent by the line card box 0 as an example. The new line card box 2 can open the corresponding unicast channel according to the ID and/or port number of the line card box 0, and open the unicast channel between the new line card box 2 and the line card box 0 (2->0).

Similarly, after the new line card box 2 receives the unicast response message sent by the online line card box 1, it can also open the unicast channel between the new line card box 2 and the line card box 1 (2- >1). For details, please refer to the above description, which will not be repeated here.

Step 420: Realize the communication connection between the line card box in the system and the management and control server.

It should be understood that, in step 410, the channels between the various line card boxes are opened, so that the communication connection between the various line card boxes can be realized. The channel may be, for example, a management and control channel, which is used to send management and control messages (also referred to as management and control messages) between various line card boxes.

Since the control server and the control channel are not directly connected, the line card box cannot directly find the control server. Similarly, the control server cannot directly find all the line card boxes. Therefore, in this embodiment of the application, a box can be designated as a proxy box. All other line card boxes need to communicate with the control server, and only need to send the information to the agent box, and then transfer the information from the agent box to the control server. Similarly, the management and control server must communicate with other line card boxes, and also send information to the agent box, and the agent box transfers the information to other line card boxes.

In this way, on the one hand, only the agent box needs to know the location of the control server and the location of other boxes, and the other boxes and the control server do not need to care about the location of the other party, thereby reducing the complexity of the system. On the other hand, in the scale out router, after the proxy box is selected, the other line card boxes need to communicate with the control server, and only need to send the information to the proxy box, without worrying about whether the control server is online, thereby improving the flexibility of the system , Reduce the delay.

The embodiment of the present application does not specifically limit the implementation of selecting the proxy box from all the boxes. In a possible implementation, the box directly connected to the control server is selected as the proxy box.

As an example, taking FIG. 6 as an example, a detailed description will be given of the specific implementation manner of the communication connection between the line card box and the management and control server in the system.

It should be understood that, for ease of description, in FIG. 6, the line card box 0 directly connected to the management and control server is used as a proxy box, and other boxes (for example, line card box 1 and line card box 2) are used as non-agent boxes for illustration.

1. The line card box 0 as the proxy box passes through the channel to other non-agent boxes and sends unicast message 1 to the other non-agent boxes respectively.

Specifically, the line card box 0 can pass through the channel opened with other non-agent boxes (for example, line card box 1 and line card box 2), to other non-agent boxes (for example, line card box 1 and line card box 2) Send a unicast message 1. The unicast message 1 includes the information of the management and control server, the port number of the line card box 0 connected to the management and control server, and indicates that the line card box 0 is a proxy box.

For example, the unicast message 1 includes: a box role (box role) field, a server target port (server target port, server TP) field, and a server information (server information, server info) field. Among them, the box role field is set to "master agent", the server TP field is set to the port number of the line card box 0 local and the control server connection, and the server info field is set to the server's internet protocol (IP) address and media access control (media access control, MAC) address, etc.

2. Other non-agent boxes generate agent information according to the unicast message 1 sent by the line card box 0 as the agent box.

Other non-agent boxes (for example, line card box 1 and line card box 2), after receiving the unicast message 1 sent by the line card box 0 as the proxy box, can be generated locally according to the information included in the unicast message 1 respectively Agency information.

Take the line card box 1 in the non-agent box as an example. The agent information generated by the line card box 1 according to the information included in the unicast message 1 includes: agent ID, server TP, IP address and MAC address of the management and control server.

Similarly, the line card box 2 as a non-agent box can also generate proxy information based on the information included in the unicast message 1. For details, please refer to the above description, which will not be repeated here.

3. Other non-agent boxes respectively send unicast message 2 to line card box 0 as the agent box.

Specifically, other non-agent boxes can respectively send unicast message 2 to line card box 0 through the channel opened with line card box 0 as a proxy box. The unicast message 2 includes the local control port of the non-agent box. information.

Take the line card box 1 in the non-agent box as an example. Line card box 1 can send unicast message 2 to line card box 0. The unicast message 2 includes: a box role field and a control target port (control TP, ctrl TP) field. Among them, the box role field is set to "non-agent", and the ctrl TP field is set to the IP address of the local control port of the line card box 1 and the TP of the local control port.

Similarly, line card box 2 as a non-agent box can also send unicast message 2 to line card box 0. For details, please refer to the above description, which will not be repeated here.

It should be understood that the local control port information of the box can be understood as the information of the chip controlled by the box, for example, the IP address of the chip and the TP of the chip.

4. The line card box 0 as a proxy box generates forwarding information according to the unicast message 2 sent by other non-proxy boxes.

After the line card box 0 receives the unicast message 2 respectively sent by other non-agent boxes (for example, the line card box 1 and the line card box 2), the forwarding information can be locally generated according to the information included in the unicast message 2 respectively.

Take the line card box 0 receiving the unicast message 2 sent by the line card box 1 as an example. The proxy information generated by the line card box 0 according to the information included in the unicast message 2 includes: the ID of the line card box 1, the IP address of the local control port of the line card box 1, and the TP of the local control port.

In the above, the proxy box establishes the forwarding information locally, and the non-agent box establishes the agent information locally. In this way, the control server has a control message to be sent to other proxy boxes, which can be sent to the proxy box, and the proxy box forwards the control message to the corresponding non-agent box according to the established forwarding information. Similarly, other proxy boxes have control messages to be sent to the control server, which can be sent to the proxy box based on their locally established proxy information, and the proxy box forwards it to the control server directly connected to it.

As an example, the management and control server has a management and control message 1 sent to the non-agent line card box 1. The control server can send the control message 1 to the line card box 0 as the proxy box through the panel port, and the control message 1 indicates that the message is sent to the line card box 1. The control server can determine the IP address of the local control port of the line card box 1 and the TP of the local control port according to the control message 1 and the forwarding information. And according to the IP address of the local control port of the line card box 1 and the TP of the local control port, the control message 1 is unicast forwarded to the line card box 1 through the in-band switching network (the channel opened between each box).

As an example, in the embodiment of the present application, the management and control message 1 may include one or more of the following: software version of the box, control information for the box, configuration information for the box, entry information generated by the management and control server, and so on.

As another example, the non-agent line card box 1 has a control message 2 sent to the control server. The line card box 1 can unicast the control message 2 to the line card box 0 as the proxy box through the in-band switching network (the channel opened between each box) according to the proxy ID in the proxy information stored locally. The destination IP address in the message is the IP address of the server, and TP is the TP of the server. After line card box 0 receives the control message 2, according to the destination IP address as the server's IP address, and TP is the server's TP, it unicasts the control message 2 to the control server through the panel port connected to the control server.

It should be understood that, in this embodiment of the present application, the management and control message 2 may be a non-agent box restore management and control confirmation message to the management and control server, or report the status information of the device.

Optionally, in some embodiments, in the scale out router, each box has its own time stamp. In the process of sending data packets through the in-band channel of the scale out router, if the time stamp of each box is inconsistent, It will cause fragmentation of packets, and disorder will occur during reorganization. Therefore, in a scale out router, if a data message is sent, each box needs to synchronize the time stamp.

In the embodiment of the present application, through the in-band control plane, a master time stamp box is negotiated among the line card boxes that have been online, and the remaining boxes are follower boxes. For example, referring to Figure 7, the main time-scale box periodically broadcasts its own time-scale, makes time-scale notifications, and the follow-up box receives the time-scale notification, and synchronizes its own time-scale. Among them, the content notified by the main time stamp box may include: own time stamp and own box ID (Box ID).

There are many ways to select the main time-scale box, which is not specifically limited in this application. In one possible implementation, the box directly connected to the management server can be selected as the main time stamp box. In another possible implementation, the box with the largest or smallest Box ID can also be selected as the main time stamp box.

Optionally, in some embodiments, a box directly connected to the selection and control server is selected as the main time stamp box as an example. When the connection relationship between the control server and the boxes in the system changes, there will be multiple boxes with the role of "direct connection" in a short period of time. In other words, in a short period of time, there will be multiple master time stamp boxes. At this point, you need to wait for N cycles, and then set yourself as the main time stamp box.

The specific implementation of how to synchronize time stamps when there are multiple master time stamp boxes will be described in detail below with reference to FIGS. 8-9.

FIG. 8 is a schematic flowchart of a method for time stamp synchronization when there are multiple master time stamp boxes provided by an embodiment of the present application. The execution subject of the method shown in FIG. 8 is the box A directly connected to the management and control server in the scale out router. As shown in Fig. 8, the method may include steps 810-880, and steps 810-880 will be described in detail below.

Step 805: Box A determines that there is no master time stamp box in the scale out router, and the time stamp is initialized synchronously.

In the case of box A in the scale out router, if it is determined that there is no master time stamp box in the scale out router, the time stamp of this box A does not change with the time stamps of other boxes.

Step 810: Box A receives the notification sent by the data plane management module UC module, and promotes itself to a directly connected box.

Step 815: Box A sets itself as the main time stamp box.

Step 820: Box A judges whether there are two master time stamp boxes in the scale out router.

Specifically, if there are other boxes besides box A in the scale out router that are master time stamp boxes, then this box A will receive the time stamp channels sent by other master time stamp boxes. If box A receives the time stamp channel sent by other master time stamp boxes, it can be determined that there are two master time stamp boxes in the scale out router.

Step 823: Maintain the time stamp initialization state for N cycles.

In this embodiment of the application, regardless of whether there are two master time stamp boxes in the scale out router, the time stamp initialization state is maintained for N cycles.

Step 825: If the box A determines that there are multiple synchronization areas, it can be delayed for a period of time.

Step 830: If box A determines that the previous box is disconnected from the box directly connected to the control server, there should be only one box A and one directly connected box at this time.

Step 835: Box A determines whether the time scale it follows is its own time scale.

If the time scale followed by box A is not its own time scale, step 840 is executed.

If the time scale followed by box A is its own time scale, step 845 may be executed.

Step 840: An error is reported, and the time stamp synchronization is initialized.

If the time stamp followed by box A is not its own time stamp, after an error is reported, the time stamp synchronization is initialized, and step 823 is continued.

Step 845: If Box A determines that there is no synchronization zone, inform UC that a heartbeat message can be sent.

It should be understood that if box A determines that there is no synchronization zone, it can be understood that there is only one directly connected box in the scale out router. This directly connected box can be used as the main time stamp box to send heartbeat messages to other follow time stamp boxes for Mark the box at any time to notify its own main time stamp.

Step 850: There is only one directly connected box, and the system works normally.

Step 855: Box A disconnects the server.

Step 860: Before the UC detects the local disconnection, it determines whether there are other boxes directly connected to the control server.

If UC determines that there are other boxes directly connected to the management and control server before the local connection is disconnected, step 865 is executed.

If the UC determines that no other boxes are directly connected to the management and control server before the local connection is disconnected, step 870 is executed.

Step 865: Make sure that there are two directly connected boxes and two main time stamp boxes in the system.

Step 867: It can be determined that there are multiple synchronization areas in the system at this time.

Step 870: UC detects that box A is a non-primary time-scale box, and channel box A reduces itself to a non-primary time-scale box.

Step 875: Box A notifies UC to stop sending heartbeat messages.

It should be understood that if box A is a non-primary time stamp box, box A cannot advertise its own time stamp to other boxes in the system. Therefore, box A can notify UC to stop sending heartbeat messages.

Step 880: Determine whether there are other boxes in the system directly connected to the control server.

If it is determined that there are other boxes in the system directly connected to the control server, proceed to step 850.

If it is determined that no other boxes in the system are directly connected to the control server, proceed to step 805.

FIG. 9 is a schematic flowchart of another method for time stamp synchronization when there are multiple master time stamp boxes according to an embodiment of the present application. The execution subject of the method shown in FIG. 9 is box B in the scale out router that is not directly connected to the management and control server. As shown in FIG. 9, the method may include steps 910-950, and steps 910-950 will be described in detail below.

Step 910: Box B determines that there is no master time stamp box in the scale out router, and the time stamp is initialized synchronously.

Step 920: Box B periodically detects the local time stamp following state.

Step 930: Box B judges whether it follows other main time stamp boxes.

If box B judges that it follows other main time stamp boxes, step 940 is executed.

If box B determines that it does not follow other main time stamp boxes, step 950 is executed.

Step 940: Box B notifies UC that a heartbeat message can be sent.

If box B follows other main time stamp boxes, time stamp synchronization can be realized, thereby sending a heartbeat message and opening a data channel to facilitate sending data messages through the data channel.

Step 950: Box B notifies UC to stop sending heartbeat messages.

If box B does not follow other main time stamp boxes, time stamp synchronization is not achieved between box B and other boxes, data channels cannot be opened between the boxes, and data messages cannot be sent. Therefore, UC can be notified to stop sending heartbeat messages.

Optionally, in some embodiments, a dual channel is abstracted on the data link between the line card box and the switch box. For example, referring to Figure 9, the physical link between the line card box and the switch box abstracts a data channel and a control channel. Among them, the data channel uses data packets, and the control channel uses management and control information. The server uses this control channel when it manages and controls the line card box and the switch box.

In the embodiments of the present application, a new control heart cell type can be added to the message to distinguish between data messages and control messages. Among them, the data message can also be called data information, and it takes the data channel. Control messages can also be referred to as management and control information, and go through the management and control channel.

Optionally, in some embodiments, it is also possible to force the control message to be encapsulated in one cell, so that the control message does not need to be split and reassembled, thereby eliminating the need to rely on time stamp synchronization. That is to say, in this case, there is no need to select the main time-scale box, and there is no need to synchronize the time-scales between the following boxes according to the information of the main time-scale.

It should be noted that, in the embodiment of the present application, the management and control server, the line card box, and the switching box are interconnected through the management and control channel, and the management and control channel will not be disconnected even when the data channel is disconnected due to the time stamp asynchronous.
