An embodiment of the present application provides a network device (such as a router, a switch, a server, and the like), which is shown in fig. 1 and is a schematic structural diagram of the network device, where the network device may include but is not limited to: the power module 11, the detection module 12, the energy storage circuit 13 and the service processing module 14, and the service processing module 14 may include, but is not limited to: the logic device 141, the switch chip 142, and the CPU143, of course, the service processing module 14 may further include other sub-modules such as an internal memory, and the sub-modules of the service processing module 14 are not limited.
In this embodiment, the logic device 141 is disposed between the CPU143 and the switch chip 142, and the logic device 141 is configured to send notification information to the monitoring host when an abnormality occurs in the power module 11. Among them, the logic device 141 may include but is not limited to: an FPGA (Field Programmable Gate Array) chip, and a CPLD (Complex Programmable Logic Device) chip. Of course, the logic device 141 may be other types of chips, which is not limited in this respect.
Referring to fig. 1, when the power module 11 works normally, the power module 11 can supply power to the service processing module 14, and the power module 11 stores electric energy in the energy storage circuit 13. When the power module 11 is abnormal, the power module 11 cannot supply power to the service processing module 14, but the energy storage circuit 13 supplies power to the service processing module 14 for a period of time, so that the service processing module 14 sends notification information to the monitoring host.
When the energy storage circuit 13 supplies power to the service processing module 14, not all the sub-modules in the service processing module 14, but only the logic device 141 and the switch chip 142 in the service processing module 14, and since the power does not need to be supplied to the sub-modules such as the CPU143 and the memory in the service processing module 14, the total power consumption of the service processing module 14 can be reduced, and the implementation difficulty and cost of the energy storage circuit 13 can be reduced.
To sum up, in the embodiment of the present application, when the power module 11 works normally, the power module 11 supplies power to the service processing module 14. When the power module 11 is abnormal, the power module 11 cannot supply power to the service processing module 14, and the energy storage circuit 13 supplies power to the logic device 141 and the switch chip 142.
When the power module 11 works normally, the power module 11 can supply power to the service processing module 14, and the power module 11 can store electric energy in the energy storage circuit 13, that is, when the power module 11 works normally, the energy storage circuit 13 can store electric energy. Because the power module 11 supplies power to the service processing module 14, the service processing module 14 can work normally and can send messages normally.
Specifically, the CPU143 may send the message a to the logic device 141 through the data bus 1, the logic device 141 may forward the message a to the switch chip 142 through the data bus 2, and the switch chip 142 may forward the message a to an external device, which is not limited to the forwarding process of the message a.
In addition, after receiving the message B, the switch chip 142 may send the message B to the logic device 141 through the data bus 2, and the logic device 141 may forward the message B to the CPU143 through the data bus 1, so that the CPU143 processes the message B, and the forwarding process of the message B is not limited.
When the power module 11 is operating normally, the CPU143 may also obtain notification information and send the notification information to the logic device 141; the logic device 141 may store the notification information after receiving the notification information, and for example, the logic device 141 may store the notification information.
The CPU143 may transmit the notification information to the logic device 141 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 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, etc., and the data bus 1/data bus 2 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 12 can detect that the power module 11 is abnormal, that is, power failure abnormality occurs, and therefore, the first abnormal information can be sent to the energy storage circuit 13, and the second abnormal information can be sent to the logic device 141.
The energy storage circuit 13 may supply power to the logic device 141 and the switch chip 142 when receiving the first exception information, but the energy storage circuit 13 prohibits power supply to other sub-modules in the service processing module 14 except for the logic device 141 and the switch chip 142. Specifically, when the energy storage circuit 13 receives the first abnormality information, it is known that the power supply module 11 is abnormal, and different from the conventional manner, the energy storage circuit 13 supplies power to only the logic device 141 and the switch chip 142 instead of supplying power to all sub-modules in the service processing module 14, and does not supply power to other sub-modules (such as the CPU143 and the memory, etc.) in the service processing module 14. Because the power supply for the sub-modules such as the CPU143 and the memory is not needed, the implementation difficulty of the energy storage circuit 13 is reduced.
When receiving the second abnormality information, the logic device 141 may read notification information stored in advance from the logic device 141 and send the notification information to the switch chip 142. Further, the switch chip 142 may send the notification information to the monitoring host after receiving the notification information.
In the above embodiment, the switch chip 142 sends the notification information to the monitoring host, and in order to make the switch chip 142 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 CPU143 may further obtain feature information, where the feature information is used to indicate that the notification information is on the output interface of the switch chip 142, and then send the feature information to the logic device 141; logic device 141, upon receiving the characterization information, may store the characterization information.
The CPU143 may query the routing table by monitoring the IP address of the host, obtain an egress interface corresponding to the IP address, and send the egress interface to the logic device 141. Alternatively, when the IP address of the monitoring host changes, the CPU143 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 141.
The logic device 141, upon receiving the second abnormality information, may send the notification information to the switch chip 142 together with the feature information. After receiving the notification information and the feature information, the switch chip 142 may send the notification information to the monitoring host through the output interface indicated by the feature information.
In the second method, the output interface of the notification information on the switch chip 142 is configured in advance on the switch chip 142. When receiving the second abnormal information, the logic device 141 sends notification information to the switch chip 142; after receiving the notification information, the switch chip 142 sends the notification information to the monitoring host based on the pre-configured output interface.
Through the two manners, the switch chip 142 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 CPU143 periodically generates notification information and transmits each generated notification information to the logic device 141, so that the logic device 141 stores the latest notification information, that is, replaces the already stored notification information each time a new notification information is received. Since the CPU143 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, thereby ensuring the accuracy of the generation time.
Mode B, CPU143 may generate notification information that includes the generation time (e.g., time a) and send the notification information to logic device 141 to cause logic device 141 to store the notification information. After the logic device 141 sends the notification information to the monitoring host, the monitoring host may obtain the generation time (e.g., 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 receive the notification information (e.g., time B) as the abnormal time of the power module 11.
Mode C, the logic device 141 may further include a timer. CPU143 may generate notification information, which may include a generation time (e.g., time a), and send the notification information to logic device 141 to cause logic device 141 to store the notification information and start a timer of logic device 141. When the notification information needs to be sent to the monitoring host, the logic device 141 may first read the value of the timer, and if the value is 200 seconds, the logic device 141 may modify the generation time of the notification information to be 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 the embodiment of the present application, when the power module 11 is abnormal, the energy storage circuit 13 only needs to supply power to the logic device 141 and the switch chip 142 in the service processing module 14, and does not need to supply power to other sub-modules (e.g., the CPU143, the memory, etc.) in the service processing module 14, so that the total power consumption of the service processing module 14 is reduced, and the implementation difficulty, the selection difficulty, and the cost of the energy storage circuit 13 are greatly reduced. Further, the notification information can be transmitted to the monitoring host by the logic device 141 without relying on the CPU143 to transmit the notification information to the monitoring host, so that the transmission reliability of the notification information can be improved.
In the above embodiment, the logic device 141 is referred to, and the structure of the logic device 141 will be described below.
Referring to fig. 2, the logic device 141 may include: a first queue sub-module 1411, a second queue sub-module 1412, a selector sub-module 1413, and a transmitter sub-module 1414. The First queue submodule 1411 may be a First-in First-out (FIFO) module, the second queue submodule 1412 may also be a FIFO module, and the selector submodule 1413 may be a switch module.
When the power module 11 works normally, the selector sub-module 1413 is configured to conduct the first queue sub-module 1411 and the second queue sub-module 1412, so that the first queue sub-module 1411 sends the message to the second queue sub-module 1412, and the second queue sub-module 1412 sends the message to the switch chip 142.
When the power module 11 is abnormal, the selector sub-module 1413 may turn on the packet transmitter sub-module 1414 and the second queue sub-module 1412 when receiving the second abnormal information, and turn off the first queue sub-module 1411 and the second queue sub-module 1412, so that the packet transmitter sub-module 1414 sends the notification information to the second queue sub-module 1412, and the second queue sub-module 1412 sends the notification information to the switch chip 142.
Referring to fig. 3, the logic device 141 may further include: a control register 1415 and a message template sub-module 1416, the control register 1415 being for storing the packet transmission rate, the message template sub-module 1416 being for storing the notification information. On this basis, the packetizer sub-module 1414 may read the packet sending rate from the control register 1415 and may read the notification information from the message template sub-module 1416, and may then send the notification information to the second queue sub-module 1412 according to the packet sending rate, that is, the packetizer sub-module 1414 may periodically send the notification information to the second queue sub-module 1412 according to the packet sending rate. Further, each time the second queue sub-module 1412 receives a notification message, the notification message is sent to the switch chip 142, and the switch chip 142 sends the notification message to the monitoring host.
The message template sub-module 1416 is further configured to store feature information and notification information, where the feature information is used to indicate that the notification information is on the outgoing interface of the switch chip 142; for example, if the switch chip 142 is connected to the monitoring host through the interface 1421, the characteristic information may be the interface 1421.
On this basis, the packet sender sub-module 1414 can read the feature information and the notification information from the message template sub-module 1416 and send the feature information and the notification information to the second queue sub-module 1412 according to the packet sending rate. The second queue sub-module 1412 may send the characteristic information and the notification information to the switch chip 142 after receiving the characteristic information and the notification information. After receiving the feature information and the notification information, the switch chip 142 may send the notification information according to the feature information; for example, if the feature information is the interface 1421, the switch chip 142 may send the notification information through the interface 1421.
Referring to fig. 4, the logic device 141 may further include: a management submodule 1417; the management submodule 1417 is configured to obtain a packet sending rate, feature information, and notification information, store the packet sending rate in the control register 1415, and store the feature information and the notification information in the message template submodule 1416.
On the basis of the logic device 141 of fig. 4, the above-described scheme is explained below with reference to specific embodiments.
When the power module 11 works normally, the CPU143 may send a message a (a data message that needs to be sent to an external device for a normal service) to the first queue submodule 1411 of the logic device 141 through the data bus 1, and as the selector submodule 1413 conducts the first queue submodule 1411 and the second queue submodule 1412, after receiving the message a through the data bus 1, the first queue submodule 1411 sends the message a to the second queue submodule 1412, and the second queue submodule 1412 may forward the message a to the switch chip 142 through the data bus 2, and the switch chip 142 may forward the message a to the external device.
After receiving the message B (i.e., the data message sent by the external device of the normal service to the network device), the switch chip 142 may send the message B to the second queue submodule 1412 of the logic device 141 through the data bus 2, and as the selector submodule 1413 conducts the first queue submodule 1411 and the second queue submodule 1412, after receiving the message B through the data bus 2, the second queue submodule 1412 sends the message B to the first queue submodule 1411, and the first queue submodule 1411 forwards the message B to the CPU143 through the data bus 1, so that the CPU143 processes the message B.
CPU143 may also obtain notification information and send the notification information to management submodule 1417 of logic device 141 via the management bus, and after receiving the notification information, management submodule 1417 stores the notification information in message template submodule 1416. The CPU143 may further obtain the feature information, and send the feature information to the management sub-module 1417 of the logic device 141 through the management bus, and after receiving the feature information, the management sub-module 1417 stores the feature information in the message template sub-module 1416.
The characteristic information is used to indicate that the notification information is output from the interface of the switch chip 142, for example, if the switch chip 142 is connected to the monitoring host through the interface 1421, the characteristic information may be the interface 1421.
The management submodule 1417 may also obtain a packet transmission rate for the notification information and store the packet transmission rate in the control register 1415, indicating that the notification information is periodically transmitted at the packet transmission rate. The packet sending rate may be generated by the CPU143 according to actual needs and sent to the management submodule 1417, or the management submodule 1417 itself may be generated according to actual needs, which is not limited herein.
The management sub-module 1417 may further obtain working parameters (e.g., a working rate, a duplex mode, a queue length, etc.) of the first queue sub-module 1411, and store the working parameters of the first queue sub-module 1411 in the control register 1415, which indicates that the first queue sub-module 1411 works according to the working parameters. Also, the first queue submodule 1411 may be coupled to the control register 1415 and read operating parameters of the first queue submodule 1411 from the control register 1415.
