Description

Optical interface management system, method, device, programmable logic device and storage medium

Technical Field

The embodiment of the invention relates to the technical field of network communication, in particular to an optical port management system, a method, a device, a programmable logic device and a storage medium.

Background

With the rapid development of internet technology, the bandwidth requirement is higher and higher, more and more transmission networks mainly based on twisted-pair copper cable connection mode are replaced by optical fiber media with low cost, easy deployment, high bandwidth, strong expandability and longer transmission distance, and the number of optical interfaces in network communication equipment such as switches and routers is continuously increased and accounts for more and more.

However, in embedded systems, especially network devices such as switches, which are designed using Application Specific Integrated Circuit (ASIC) chips, the hardware resources are very limited, for example, the network device monitors a signal of a single optical port through each input/output (IO) interface. A single optical port may have 5 kinds of signals at most to be monitored, but at most 32 IO interfaces that can be provided by the current network device exist, and if each optical port has 5 kinds of signals to be monitored, the network device can only manage about 6 optical ports at most, which is difficult to meet the actual requirement. In some scenarios, the number of optical ports that can be connected to the network device can also be increased by reducing the signal types monitored by a single optical port (e.g., only one or two signals are monitored for each optical port, and the other signals are not monitored), but the number of optical ports increased in this manner is very limited.

In summary, the conventional optical interface management system utilizes the IO interface to monitor each signal of a single optical interface, and the scalability of the number of optical interfaces is poor, so that it is impossible to realize comprehensive and efficient monitoring and management of a large number of optical interfaces and multiple signals.

Example one

Fig. 1 is a schematic structural diagram of an optical port management system according to an embodiment of the present invention. The present embodiment is applicable to a case where a plurality of optical ports are managed. As shown in fig. 1, the system includes: a network device 100, a programmable logic device 200, and a plurality of optical ports 300; the programmable logic device 200 is configured to monitor a signal state of each optical port 300 according to a value of the register and a register mapping relationship, and report an interrupt signal to the network device 100 when a signal state of any one optical port 300 is a preset state; wherein, the register mapping relation comprises: a single byte in the register of programmable logic device 200 corresponds to one signal and a single bit in the single byte corresponds to one optical port; each value of a single bit in a single byte corresponds to a signal state.

Specifically, the network device 100 may be a switch, a router, or a network device designed using an ASIC chip. Programmable Logic Device 200 may be a Complex Programmable Logic Device (CPLD).

The register of the programmable logic device 200 can be used to store the signal status of each signal of each optical port 300 to indicate whether each signal of each optical port 300 is in a normal state or an abnormal state, thereby monitoring each optical port 300. A single byte of the register corresponds to one signal, and a single bit in the single byte corresponds to one optical port, that is, a single byte (including 8 bits) can be used to store the state of at most one signal of 8 optical ports, on this basis, multiple bytes can be used to implement monitoring of multiple signals of multiple optical ports. Each value of a single bit in a single byte corresponds to a signal state, for example, a value of a bit in a byte is 0, the bit corresponds to an optical port 1, and the byte corresponds to an optical module presence signal, which indicates that the optical module presence signal of the optical port 1 is in a state; if the bit value in the byte is 0, it indicates that the optical module of the optical port 1 is in another state in the bit signal. Furthermore, when the number of optical ports to be monitored is large and the types of signals are large, the number of the optical ports and the types of the signals can be flexibly expanded by expanding bytes and bits used for storing the states of the signals in the register.

The preset state may refer to a recovery from a normal state or an abnormal state (an abnormal state may also be understood as a fault state, and may be one or more signals of the optical port are abnormal, for example, the optical module is not in place or the optical signal is lost, etc.). In some embodiments, the preset state may refer to a state after the signal of the optical port is switched, for example, the optical port is switched from a normal state to an abnormal state, or is switched from the abnormal state to the normal state.

According to the value of the register and the register mapping relationship, when detecting that the signal of any optical port 300 is in an abnormal state or recovers to a normal state, the programmable logic device 200 may report a corresponding interrupt signal to the network device 100 to notify the network device 100 of which optical port is interrupted and whether the signal of the optical port is normal, so that the network device 100 can use the optical port with normal signal to communicate with other devices in the network in real time.

Optionally, the signal of each optical port includes the following five types: an optical module presence signal (PRE); a LOSs of Optical Signal (LOS); an emitted optical signal failure signal (TX _ FAIL); transmitting an optical signal enable signal (TX _ DIS); and a RATE control signal (RATE).

Table 1 is a register mapping table provided in this embodiment. As shown in table 1, the register addresses of the programmable logic device 200 include 8 bits, and 256 addresses can be addressable at maximum, and each address can store one byte (i.e. 8 bits) of data; each optical port has 5 signals to be monitored, so each signal can occupy 1 byte for expression, and the states of the five signals of the optical port can be recorded by using 5 bytes. In addition, the monitoring requirements for 1-8 optical ports can be met in each byte.

TABLE 1 register mapping Table

Setting the address range of the registers to Reg _ addr [4 ] according to the register mapping relationship shown in table 1, so that 8 optical ports can be managed; the whole addressing space has 256 addresses, if 5 signals are monitored, the maximum manageable number of optical ports can reach as many as 400, thereby meeting the actual requirement.

In the optical interface management method provided by the embodiment of the present invention, by using a programmable logic device and reasonably designing a register mapping relationship, data exchange of multiple optical interfaces and monitoring of multiple signals are realized, expansion of the number of optical interfaces of a network device is supported, and management efficiency of multiple optical interfaces is improved.

Optionally, the preset state includes an abnormal state and a normal recovery state; correspondingly, the interrupt signal comprises a first interrupt signal and a second interrupt signal; the programmable logic device 200 is specifically configured to: under the condition that any bit in any byte is a first value, determining that the signal state of the corresponding type signal of the optical port corresponding to the bit in the byte is an abnormal state, and reporting a first interrupt signal to the network device 100; when any bit in any byte is changed to the second value, the signal state of the corresponding type of signal of the optical port corresponding to the bit in the byte is determined to be the recovered normal state, and a second interrupt signal is reported to the network device 100.

Exemplarily, a value of a certain bit in one byte is 1, the bit corresponds to an optical port 1, and the byte corresponds to an optical module presence signal, which indicates that the optical module presence signal (switched from a normal state) of the optical port 1 is in an abnormal state, at this time, the programmable logic device 200 may report a first interrupt signal to the network device 100, where the first interrupt signal may include an optical port identifier of the corresponding optical port and a signal type of the optical port, for example, an interrupt signal of a set time duration (e.g., 5 ms) to indicate which optical port is abnormal, and may also indicate which signal of the optical port is abnormal; if the bit value in the byte is changed to 0, it indicates that the optical module at optical port 1 recovers to a normal state in the bit signal (switched from an abnormal state), and at this time, the programmable logic device 200 may also report a second interrupt signal to the network device 100 to indicate which optical port recovers to the normal state, and may also indicate specifically which signal of the optical port recovers to the normal state.

It should be noted that, in the prior art, the system resources occupied when the optical interface is interrupted are too large. Specifically, when a fault occurs in the optical fiber line, the fault needs to be reported to the network device in time, so that the backup line can be switched in time, and communication interruption is avoided. However, the LOS signal of the optical port is a critical signal that needs to be reported to the network device, but the signal is only abnormal in a fixed level manner, and after such interruption occurs in one optical port, the interruption resource cannot be released, so that if there is interruption in another optical port, another interruption cannot be reported, and multiple optical ports cannot share the external interruption, that is, the network device cannot process multiple interruption events at the same time within a certain time period. In addition, the level is not reset to the initial state if a fault still exists after detection by software. Under the condition, a large amount of system resources are consumed to process the interrupt report, and if the interrupt report is not processed properly, the phenomena of system hang-up, system failure and system false-up are caused. However, the optical interface management system of this embodiment may implement data exchange and monitoring of multiple signals for multiple optical interfaces by using the programmable logic device, and when any optical interface is interrupted or recovered, the programmable logic device may report a corresponding interrupt signal to the network device, and the multiple optical interfaces may share an external interrupt, thereby improving the efficiency and reliability of optical interface management.

Optionally, the network device 100 is further configured to query the value of the register when receiving the interrupt signal, and use any optical port 300 whose bit in the corresponding byte is the second value for communication. On this basis, the network device 100 may manage the interrupt optical interface according to the value of the register and the register mapping relationship, and select an optical interface 300 with a normal signal for communication; if the signal state of the optical port for communication is abnormal, the optical port 300 with normal signal can be switched to in time, thereby ensuring the communication quality.

Fig. 2 is a flowchart for managing an optical interrupt according to a second embodiment of the present invention. Taking a network device as a switching chip and a programmable logic device as a CPLD as an example, as shown in fig. 2, the CPLD continuously monitors signals of n optical ports; when any one or more optical ports are interrupted, the CPLD writes an interruption event into a register, namely, updates the values of corresponding bytes and corresponding bits in the register, and reports an interruption signal to a switching chip, wherein the register is used for storing the interrupted optical ports and signal states, if the optical port signal is interrupted caused by an abnormal state, the values of the corresponding bytes and the corresponding bits are first values, and if the optical port signal is interrupted caused by recovering the normal state, the values of the corresponding bytes and the corresponding bits are second values; after the switching chip receives the interrupt signal, the switching chip can access the register through the SPI bus, inquire the optical port in which the interrupt occurs, then switch the optical port, and use any optical port (namely any optical port in which the signal is in a normal state) with the bit in the corresponding byte as the second value for communication so as to ensure the normal operation of optical fiber communication. Therefore, whether the interrupt signal of the optical interface is removed or not, the normal work and the line switching of the system cannot be influenced, the reporting among the interrupts of the optical interfaces is not influenced, and after the interrupted optical interface returns to normal, the system can not process the line in a closed loop manner, so that the expandability and the reliability of the system are ensured.

Optionally, the number of programmable logic devices 200 is at least two; the system further comprises: the relay device 400 is configured to analyze a command of the network device 100 to determine the programmable logic device 200 corresponding to the command, and forward the command to the corresponding programmable logic device 200, so that the corresponding programmable logic device 200 performs an operation on a corresponding optical port according to the command; and is further configured to combine the interrupt signals of the programmable logic devices 200 into one interrupt signal and report the interrupt signal to the network device 100.

There may be a plurality of programmable logic devices 200, and each programmable logic device 200 may be configured to monitor signals of at least one optical port 300. On this basis, the number of optical ports can be further expanded by expanding the number of the programmable logic devices 200, and large-scale optical port communication is realized. The relay device 400 may also be implemented by a CPLD.

The relay device 400 is connected to the network device 100 and each programmable logic device 200, and when receiving a command from the network device 100, the relay device 400 may determine to which programmable logic device or devices 200 the command needs to be sent by analyzing the command, thereby implementing the distribution of the command. Specifically, the command of the network device 100 may be for one or more programmable logic devices 200, and may be a read command or a write command. Commands for different programmable logic devices 200 may be distinguished by different identification or numbering, etc. For example, a command of the network device 100 may be sent through a data packet or a message, an identification field may be carried in a header of the data packet or a header of the message, where the identification field is used to indicate a unique identifier or a number of the programmable logic device 200, and after receiving the command, the relay device 400 may identify which programmable logic device 200 the receiving end of the command is according to the identification field, and forward the command to the corresponding programmable logic device 200, so that the editable logic device 200 performs corresponding operations on the relevant optical interface according to the command, for example: read or write operations to the optical port data.

In addition, there may be a plurality of programmable logic devices 200 reporting the interrupt signal, and the relay device 400 may combine the interrupt signals reported by the plurality of programmable logic devices 200 into one interrupt signal (according to the set frequency) and uniformly send the one interrupt signal to the network device 100, so as to reduce network resources occupied by frequently reporting the interrupt signal and also reduce the operating pressure of the network device 100. The merging may refer to that, in one interrupt signal, the optical port identifier of the optical port in the abnormal state or the normal state recovery of the plurality of programmable logic devices 200 and the signal type of each optical port are carried, for example, the optical module in the optical port a of the programmable logic device 1 recovers the normal state in place, and the optical signal loss signal of the optical port B of the programmable logic device 2 is the normal state recovery, so that the interrupt signal generated by the programmable logic device 1 and the interrupt signal generated by the programmable logic device 2 may be merged into one interrupt signal and reported to the network device 100. For another example, the interrupt signal may be reported once per second to notify the network device 100 which optical port the interrupt occurs in the second and whether the signal of the optical port is normal, so that the network device 100 uses the optical port with the normal signal to communicate with other devices in the network in real time.

Fig. 3 is a schematic structural diagram of an optical port management system according to an embodiment of the present invention. As shown in fig. 3, the network device 100 may be a switch chip (ASIC chip), and the programmable logic device 200 and the relay device 400 are both CPLDs. Expansion of IO and interrupt resources is performed by means of a Serial bus, such as a Serial Peripheral Interface (SPI) bus, an Inter-Integrated Circuit (I2C) bus, even a 1wire bus, and the like, which is externally hung with a CPLD programmable logic device. x denotes the number of serial data buses, m denotes the number of SMI buses, n denotes the number of optical ports, and p denotes the number of programmable logic devices (CPLD chips) used in the system.

In fig. 3, a DDR RAM (Double Data Rate Access Memory), a non-volatile Flash Memory (NOR Flash), a NAND Flash Memory (NAND Flash), a USB interface, and the like constitute a hardware subsystem 500 for running software. In addition, the system also comprises an Ethernet Physical layer (PHY) chip; a Direct current-Direct current (DC-DC) power supply and a clock generator may also be included.

It should be noted that, the network device may generally provide an SPI bus, which may be used to read software programs stored in the external Flash on one hand, and provide an additional bus chip on the other hand, so that the network device may be used to extend other external devices based on the SPI interface. In this embodiment, in order to enable the network device to perform data interaction with the programmable logic device through the SPI interface, an access protocol with a set format is defined to describe a timing sequence of the SPI bus interface, and on this basis, a communication mechanism is established between the switching chip and the CPLD through the SPI bus.

Optionally, the programmable logic device 200 is further configured to receive a command of the network device 100, analyze the command to obtain an operation instruction, an optical port corresponding to the operation instruction, and optical port data of the optical port, and process the optical port data of the corresponding optical port according to the operation instruction.

In this embodiment, the network device 100 and the programmable logic device 200 communicate with each other by using an access protocol with a set format, and with this unified access protocol format, the programmable logic device 200 may analyze a command of the network device 100, and determine an operation instruction indicated by the command, where the operation instruction mainly includes two types: a read instruction and a write instruction; the optical port corresponding to the operation instruction may also be determined, for example, a register address is indicated in the command, each optical port corresponds to a unique register address, and the programmable logic device 200 may determine which optical port the operation instruction is executed on according to the register address indicated in the command; the port data for that port in the command may also be determined. On this basis, the network device 100 may perform optical interface data exchange with each optical interface 300, including writing optical interface data from the network device 100 to the corresponding optical interface 300, or reading optical interface data from the corresponding optical interface 300 and feeding back the optical interface data to the network device 100.

Optionally, the command of the network device 100 includes an address field, a register address field, and an optical interface data field, where the address field is used to determine the type of the operation instruction, the register address field is used to determine the optical interface corresponding to the operation instruction and the register address thereof, and the optical interface data field is used to determine the optical interface data carried in the command.

The address field determines whether the type of the operation instruction is a read instruction or a write instruction; the register address field is used for indicating an optical port corresponding to the operation instruction and a register address thereof, namely a register address for reading or writing data of the optical port, the register addresses corresponding to different optical ports are different, and the optical port corresponding to the operation instruction can be uniquely determined according to the register address; the optical interface address field is used to carry optical interface data, where the first optical interface data may be optical interface data that is sent by the network device 100 and is to be written into the corresponding optical interface 300, and the second optical interface data may be optical interface data that is stored in the corresponding optical interface 300 and needs to be read out and fed back to the network device 100.

In one case, the operation instruction is a write instruction. In this case, the programmable logic device 200 is configured to extract the first optical port data sent by the network device from the optical port data field according to the write instruction, and store the first optical port data in the register address of the optical port corresponding to the register address field. On the basis of the data exchange, the data exchange in the direction from the network device 100 to the optical interface 300 can be realized.

Alternatively, the operation instruction is a read instruction. In this case, the programmable logic device 200 is configured to read the second optical port data from the register address of the optical port corresponding to the register address field according to the read instruction, and send the second optical port data carried in the optical port data field to the network device. On the basis of the data exchange, the data exchange of the optical interface from the optical interface 300 to the network device 100 can be realized.

In an embodiment, the address fields may further include a first address field and a second address field that together determine the kind of command of the network device 100.

Table 2 is a definition table of bits of an access protocol of a set format. In this embodiment, the data exchanged by a single bus access may be 4 bytes (32 bits), and the functions represented by these 4 bytes are shown in table 2. The first address field and the second address field jointly determine whether the operation instruction is a read instruction or a write instruction; the register address field of the optical port is used for determining the optical port and the register address for reading or writing the data of the optical port; the optical port address field is used to determine optical port data for the optical port.

Optionally, if the address in the first address field and the address in the second address field are the first combined address, the operation instruction is a write instruction; the programmable logic device is used for receiving first optical port data sent by the network equipment according to the writing instruction and storing the first optical port data into a register address of an optical port corresponding to the register address field.

Wherein, the writing instruction can be expressed as: and 0xad 0x1c Reg _addrReg _data, wherein the bit width of the register address field (Reg _ addr) is 8 bits, and the bit width of the optical interface data (Reg _ data) is 8 bits. And after receiving the commands, the programmable logic device receives the optical interface data sent by the SPI bus and stores the optical interface data in a register with the address Reg _ addr.

Optionally, if the address in the first address field and the address in the second address field are the second combined address, the operation instruction is a read instruction; and the programmable logic device is used for sending second optical interface data to the network equipment according to the reading instruction, and the second optical interface data is stored in the register address of the optical interface corresponding to the register address field.
