These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. Depending on the context, moreover, the word "if" is used may be interpreted as "at … …," or "when … …," or "in response to a determination.
In the embodiment of the present application, a network device (such as a router, a switch, a server, and the like) is provided, as shown in fig. 1, which is a schematic structural diagram of a network device, where the network device may include but is not limited to: the system comprises a main control board 10, a service card 20 and a backplane 30, wherein the main control board 10 and the service card 20 can be connected through the backplane 30.
The main control board 10 may include, but is not limited to: the power module 11 and the service processing module 12, the service processing module 12 may include a CPU121 and a switching chip 122, and certainly, the service processing module 12 may also include other sub-modules such as a memory, and the sub-modules of the service processing module 12 are not limited. The service cards 20 may include, but are not limited to: a detection module 21, a tank circuit 22, a logic device 23 and a physical chip 24.
In the embodiment of the present application, the service card 20 may be deployed in a network device, and the service card 20 may be connected to the main control board 10 through the backplane 30. Therefore, when the power module 11 of the main control board 10 is abnormal, the modules in the service card 20 may cooperate with each other, and finally, the notification information is sent to the monitoring host.
Referring to fig. 1, when the power module 11 is operating normally, the power module 11 can supply power to the service processing module 12 and the service card 20, and the power module 11 can store power in the energy storage circuit 22.
When the power module 11 is abnormal, the power module 11 cannot supply power to the service processing module 12 and the service card 20, but is supplied with power by the energy storage circuit 22. The tank circuit 22 only supplies power to the logic device 23 and the physical chip 24 in the service card 20 for a certain period of time when supplying power, so that the logic device 23 and the physical chip 24 send notification information to the monitoring host. However, when the energy storage circuit 22 supplies power, the main control board 10 is no longer supplied with power, that is, the service processing module 12 in the main control board 10 is not supplied with power, and since the service processing module 12 is not required to be supplied with power, the total power consumption of the network device is reduced, and the implementation difficulty and cost of the energy storage circuit 22 are reduced.
In summary, when the power module 11 works normally, the power module 11 supplies power to the service processing module 12 and the service card 20. When the power module 11 is abnormal, the power module 11 cannot supply power to the service processing module 12 and the service card 20, and the energy storage circuit 22 supplies power to the logic device 23 and the physical chip 24.
When the power module 11 works normally, the power module 11 can supply power to the service processing module 12 and the service card 20, and the power module 11 can store electric energy in the energy storage circuit 22, that is, when the power module 11 works normally, the energy storage circuit 22 can store electric energy. Because the power module 11 supplies power to the service processing module 12, the service processing module 12 can normally operate to normally receive and transmit messages.
Specifically, the CPU121 may send the message a to the switch chip 122 through the data bus, and after receiving the message a, the switch chip 122 may send the message a to the logic device 23 through the data bus. After receiving the message a, the logic device 23 may forward the message a to the physical chip 24 through the data bus, and the physical chip 24 may forward the message a to an external device, without limitation on the forwarding of the message a.
After receiving the message B sent by the external device, the physical chip 24 may send the message B to the logic device 23 through the data bus, after receiving the message B, the logic device 23 may forward the message B to the switch chip 122 through the data bus, and the switch chip 122 forwards the message B to the CPU121 through the data bus, so that the CPU121 processes the message B, and the forwarding process of the message B is not limited.
The CPU121 may also acquire notification information of the network device and transmit the notification information to the logic device 23 when the power module 11 is operating normally. The logic device 23 may store the notification information upon receiving the notification information, e.g., the logic device 23 may store the notification information in the present logic device 23.
The CPU121 may transmit the notification information to the logic device 23 via the management bus.
The notification information may include, but is not limited to, one or any combination of the following: the IP address of the network device, the device Information of the network device (such as MIB (Management Information Base) Information), the generation time of the notification Information, the IP address of the monitoring host, and the like, which are not limited herein.
The logic device 23 may include, but is not limited to: an FPGA (Field Programmable Gate Array) chip, and a CPLD (Complex Programmable Logic Device) chip. The logic device 23 may be other chips, which is not limited in this regard.
The notification information may include, but is not limited to: SNMP (Simple Network Management Protocol) alarm information (such as Trap information) or system log information (such as Syslog information). Specifically, the notification information may also be referred to as Dying Gasp (legacy information), which is information sent to the monitoring host after the network device is abnormally powered off, and may include SNMP alarm information (i.e., information generated in an SNMP format) or Syslog information (i.e., information generated in a Syslog format).
Among other things, the management bus may include, but is not limited to: a PCIE (Peripheral Component Interconnect Express) bus, an SMI (Serial Management Interface) bus, a local bus, and the like. Further, the data bus may include, but is not limited to: the ethernet bus may be, for example, a MII (Media Independent Interface) bus, a GMII (Gigabit Media Independent Interface) bus, an SGMII (Serial Gigabit Media Independent Interface) bus, or the like.
When the power module 11 is abnormal, the power module 11 cannot continue to supply power, so that the detection module 21 can detect that the power module 11 is abnormal, that is, a power failure abnormality occurs, and therefore, the first abnormality information can be sent to the energy storage circuit 22, and the second abnormality information can be sent to the logic device 23.
The tank circuit 22 may supply power to the logic device 23 and the physical chip 24 when receiving the first abnormality information. However, the tank circuit 22 disables power to the main control board 10, i.e., power is not required to the service processing module 12 in the main control board 10. Specifically, the energy storage circuit 22 learns that the power module 11 is abnormal when receiving the first abnormality information, and unlike the conventional manner, the energy storage circuit 22 does not need to supply power to the service processing module 12, but only supplies power to the logic device 23 and the physical chip 24. Because sub-modules such as the CPU121 and the memory in the service processing module 12 do not need to be powered, the implementation difficulty of the energy storage circuit 22 is reduced.
When receiving the second abnormality information, the logic device 23 may read notification information stored in advance from the logic device 23 and transmit the notification information to the physical chip 24. Further, the physical chip 24 may send the notification information to the monitoring host when receiving the notification information.
In the above embodiment, the physical chip 24 sends the notification information to the monitoring host, and in order to make the physical chip 24 know which egress interface to send the notification information to the monitoring host, the following manner may be adopted:
in the first mode, when the power module 11 normally works, the CPU121 may further obtain feature information, where the feature information is used to indicate that the notification information is on the output interface of the physical chip 24, and then send the feature information to the logic device 23; the logic device 23, upon receiving the characteristic information, may store the characteristic information.
The CPU121 may query the routing table by monitoring the IP address of the host, obtain an outgoing interface corresponding to the IP address, and send the outgoing interface to the logic device 23. Alternatively, when the IP address of the monitoring host changes, the CPU121 may query the routing table through the changed IP address to obtain an output interface corresponding to the changed IP address, and send the output interface to the logic device 23.
The logic device 23 may transmit the notification information to the physical chip 24 together with the characteristic information when receiving the second abnormality information. After receiving the notification information and the feature information, the physical chip 24 may send the notification information to the monitoring host through the output interface indicated by the feature information.
In the second method, the physical chip 24 is provided with an output interface of the notification information on the physical chip 24. When receiving the second abnormal information, the logic device 23 sends notification information to the physical chip 24; after receiving the notification information, the physical chip 24 sends the notification information to the monitoring host based on the pre-configured output interface.
Through the two ways, the physical chip 24 can send notification information to the monitoring host. Moreover, the notification information may also carry an IP address of the monitoring host, for example, a destination IP address of the notification information is the IP address of the monitoring host, so that each device between the network device and the monitoring host may send the notification information to the monitoring host by using the IP address of the monitoring host, and finally send the notification information to the monitoring host.
After receiving the notification information, the monitoring host can process the notification information because the destination IP address is the IP address of the monitoring host. For example, it is possible to learn that the network device is abnormally powered off according to the notification information, locate the location of the network device and the abnormal time, and shorten the time for recovering the network device from the abnormality.
In the above embodiment, the notification information may carry a generation time of the notification information, and in order to make the generation time the same as or close to the abnormal time of the power module 11, the following manner may be adopted:
in the method a, the CPU121 periodically generates notification information and transmits each generated notification information to the logic device 23, so that the logic device 23 stores the latest notification information, that is, replaces the already stored notification information each time a new notification information is received. Since the CPU121 periodically generates the notification information, that is, the generation time in the notification information is the current time, once the power module 11 is abnormal, the generation time in the notification information can be approximate to the abnormal time of the power module 11, and the accuracy of the generation time is ensured.
Mode B, the CPU121 may generate notification information including the generation time (e.g., time a) and transmit the notification information to the logic device 23 to cause the logic device 23 to store the notification information. After the logic device 23 sends the notification information to the monitoring host, the monitoring host may obtain the generation time (for example, time a) from the notification information, but instead of taking time a as the abnormal time of the power module 11, the monitoring host may take the time (for example, time B) when the monitoring host receives the notification information as the abnormal time of the power module 11.
Mode C, the logic device 23 may further include a timer. The CPU121 may generate notification information, which may include a generation time (e.g., time a), and send the notification information to the logic device 23 to cause the logic device 23 to store the notification information and start a timer of the logic device 23.
When the logic device 23 needs to send the notification information to the monitoring host, the value of the timer may be read first, and if the value is 200 seconds, the logic device 23 may modify the generation time of the notification information to a time a +200 seconds, and send the modified notification information to the monitoring host, so that the generation time in the notification information may be the abnormal time of the power module 11, thereby ensuring the accuracy of the generation time.
Based on the above technical solution, in this embodiment, when the power module 11 is abnormal, the energy storage circuit 22 only supplies power to the logic device 23 and the physical chip 24 in the service card 20, and does not need to supply power to the main control board 10, that is, does not need to supply power to the service processing module 12 (such as the CPU121, the memory, the switch chip 122, and the like) in the main control board 10, so that the total power consumption of the network device can be reduced, and the implementation difficulty, the selection difficulty, and the cost of the energy storage circuit 22 are reduced. Further, the notification information can be sent to the monitoring host by the logic device 23 without relying on the CPU121 to send the notification information to the monitoring host, so that the transmission reliability of the notification information can be improved. In addition, the Dying Gasp function may be deployed on the service card 20, and the main control board 10 does not need to separately implement the Dying Gasp function, that is, even if a new main control board is added to the network device, the new main control board does not need to implement the Dying Gasp function, as long as the new main control board is connected to the service card 20.
In the above embodiment, the logic device 23 is referred to, and the structure of the logic device 23 will be described below.
Referring to fig. 2, the logic device 23 may include: a first queue submodule 231, a second queue submodule 232, a selector submodule 233 and a wrapper submodule 234. The First queue submodule 231 may be a First In First Out (FIFO) module, the second queue submodule 232 may also be a FIFO module, and the selector submodule 233 may be a switch module.
When the power module 11 works normally, the selector submodule 233 is configured to turn on the first queue submodule 231 and the second queue submodule 232, so that the first queue submodule 231 sends the message to the second queue submodule 232, and the second queue submodule 232 sends the message to the physical chip 24.
When the power module 11 is abnormal, the selector submodule 233 may turn on the packet transmitter submodule 234 and the second queue submodule 232 when receiving the second abnormal information, and turn off the first queue submodule 231 and the second queue submodule 232, so that the packet transmitter submodule 234 transmits the notification information to the second queue submodule 232, and the second queue submodule 232 transmits the notification information to the physical chip 24.
Referring to fig. 3, the logic device 23 may further include: a control register 235 and a message template sub-module 236, the control register 235 may be used to store the packet sending rate, and the message template sub-module 236 may be used to store notification information. On this basis, the packetizer sub-module 234 may read the packet sending rate from the control register 235 and may read the notification message from the message template sub-module 236, and then may send the notification message to the second queue sub-module 232 according to the packet sending rate, that is, the packetizer sub-module 234 may periodically send the notification message to the second queue sub-module 232 according to the packet sending rate. Further, each time the second queue submodule 232 receives a notification message, the notification message may be sent to the physical chip 24, and the physical chip 24 may send the notification message to the monitoring host.
The message template sub-module 236 may also be configured to store feature information and notification information, where the feature information indicates that the notification information is on the outgoing interface of the physical chip 24. For example, if the physical chip 24 is connected to the monitoring host through the interface 241, the feature information may be the interface 241.
On this basis, the packetizer sub-module 234 may read the characteristic information and the notification information from the packet template sub-module 236 and send the characteristic information and the notification information to the second queue sub-module 232 according to the packet sending rate. The second queue submodule 232 may send the characteristic information and the notification information to the physical chip 24 after receiving the characteristic information and the notification information. The physical chip 24 may send the notification information according to the feature information after receiving the feature information and the notification information. For example, if the feature information is the interface 241, the physical chip 24 may send the notification information through the interface 241.
Referring to fig. 4, the logic device 23 may further include: a management submodule 237; the management submodule 237 is configured to obtain a packet sending rate, feature information and notification information, and then store the packet sending rate in the control register 235, and store the feature information and the notification information in the message template submodule 236.
On the basis of the logic device 23 of fig. 4, the above-described scheme is explained below with reference to a specific embodiment.
When the power module 11 works normally, the CPU121 may send a message a (a data message that needs to be sent to an external device in a normal service) to the switch chip 122 through the data bus, after receiving the message a, the switch chip 122 may send the message a to the first queue submodule 231 of the logic device 23 through the data bus, and since the selector submodule 233 conducts the first queue submodule 231 and the second queue submodule 232, the first queue submodule 231 may send the message a to the second queue submodule 232 after receiving the message a through the data bus, and the second queue submodule 232 may forward the message a to the physical chip 24 through the data bus, and the physical chip 24 may forward the message a to the external device.
After receiving the message B (i.e., a data message sent by an external device), the physical chip 24 may send the message B to the second queue submodule 232 of the logic device 23 through the data bus, and since the selector submodule 233 connects the first queue submodule 231 and the second queue submodule 232, the second queue submodule 232 may send the message B to the first queue submodule 231 after receiving the message B through the data bus, and the first queue submodule 231 may forward the message B to the switch chip 122 through the data bus, and the switch chip 122 forwards the message B to the CPU121 through the data bus, so that the CPU121 processes the message B.
The CPU121 may further obtain the notification information, and send the notification information to the management submodule 237 of the logic device 23 through the management bus, and after receiving the notification information, the management submodule 237 stores the notification information in the message template submodule 236. The CPU121 may further obtain the feature information, and send the feature information to the management submodule 237 of the logic device 23 through the management bus, and after receiving the feature information, the management submodule 237 stores the feature information in the message template submodule 236.
The characteristic information is used to indicate that the notification information is output from the physical chip 24, for example, if the physical chip 24 is connected to the monitoring host through the interface 241, the characteristic information may be the interface 241.
The management submodule 237 may also obtain a packet sending rate of the notification information and store the packet sending rate in the control register 235, indicating that the notification information is sent periodically according to the packet sending rate. The packet sending rate may be generated by the CPU121 according to actual needs and sent to the management submodule 237, or the management submodule 237 itself may be generated according to actual needs, which is not limited to this.
The management sub-module 237 may also obtain operating parameters (e.g., operating parameters such as operating speed, duplex mode, queue length, etc.) of the first queue sub-module 231, and store the operating parameters of the first queue sub-module 231 in the control register 235, indicating that the first queue sub-module 231 operates according to the operating parameters. Also, the first queue submodule 231 may be connected to the control register 235, and read the operating parameter of the first queue submodule 231 from the control register 235. The working parameters of the first queue submodule 231 may be generated by the CPU121 according to actual needs and sent to the management submodule 237, or may be generated by the management submodule 237 according to actual needs, which is not limited to this.
The management submodule 237 may further obtain a working parameter of the second queue submodule 232, and store the working parameter of the second queue submodule 232 in the control register 235, which indicates that the second queue submodule 232 works according to the working parameter. The second queue submodule 232 may be coupled to the control register 235 and read the operating parameters of the second queue submodule 232 from the control register 235. The working parameters of the second queue submodule 232 may be generated by the CPU121 according to actual needs and sent to the management submodule 237, or may be generated by the management submodule 237 according to actual needs.
When the power module 11 is abnormal, the detection module 21 can detect that the power module 11 is abnormal, send the first abnormal information to the energy storage circuit 22, and send the second abnormal information to the selector submodule 233 of the logic device 23. The tank circuit 22 may supply power to the logic device 23 and the physical chip 24 when receiving the first anomaly information sent by the detection module 21.
