The scheme provided by the application can be applied to the network transmission process of a city, and can realize comprehensive management of different machine rooms and different professional equipment by adding the optical modules. For ease of understanding, the following first explains several terms referred to in this application.
Optical module (optical module): the optical module is used for converting an electric signal into an optical signal at a sending end and converting the optical signal into the electric signal at a receiving end.
Modulation: the original electrical signal at the transmitting end of a communication system typically has spectral components at very low frequencies and is generally not suitable for direct transmission in a channel. Therefore, it is usually necessary to convert the original signal into a high frequency signal whose frequency band is suitable for channel transmission, and this process is called modulation. The original signal can be subjected to spectrum shifting through modulation, the modulated signal is called as a modulated signal, and the modulated signal carries information and is suitable for being transmitted in a channel.
Adjusting the top: the top-tuning technique is to superimpose a low-frequency sine or cosine modulation with small amplitude on each wavelength at the transmitting end, and when the low-frequency sine or cosine signal is superimposed on the optical wavelength, there is a modulation amplitude at the top of the optical wavelength, so the signal is called a top-tuning signal. The low-speed channel associated signal based on the Pilot tone mode may be called a low-frequency perturbation (low-frequency) signal, and may also be called Pilot tone modulation (Pilot tone modulation)
Mac (media Access Control address) address: also called physical address or hardware address, for identifying the address of the network device location.
IIC (Inter-Integrated Circuit) bus: also known as an integrated circuit bus, a serial communication bus, uses a multi-master-slave architecture. It requires only two wires to transfer information between devices connected to the bus. The master device is used to initiate the bus to transfer data and to generate a clock to open up the devices that are transferring, when any addressed device is considered a slave device. If the host wants to send data to the slave device, the host addresses the slave device first, then actively sends the data to the slave device, and finally the host terminates the data transmission; the master device addresses the slave device first if the master device is to receive data from the slave device. The host is responsible for generating the timing clock and terminating the data transfer.
MDIO (Management Data Input/Output) bus: a simple two-wire serial communication bus that connects management devices (e.g., MAC controllers, microprocessors) to a transceiver with management capabilities (e.g., a multi-port gigabit Ethernet transceiver) to control the transceiver and collect status information from the transceiver. Collectible information includes link status, transmission speed and selection, power down, low power sleep state, auto-negotiation control, loop-back mode control, etc.
The cross-network data transmission method provided by the present application is described in detail below with reference to specific embodiments.
Fig. 1 schematically shows a flowchart of a cross-network data transmission method according to an embodiment of the present application. As shown in fig. 1, the cross-network data transmission method of the present application at least includes steps S110 to S140.
Step S110, writing location information of each source end device located at a source end into a source end optical module connected to the source end device, where the location information is network location information and physical location information that can characterize the source end device.
In an embodiment, the source end and the sink end are two independent management and control systems, respectively, and the source end may be understood as a sending end, and then each source end device located at the source end may be understood as a device located at the sending end. The sink can be understood as a receiving end, and each sink device located at the sink can be understood as a device located at the receiving end.
In an embodiment, the source device is connected to the source optical module through the low-speed management interface, for example, the source device is connected to the source optical module through an IIC bus, and the source device may also be connected to the source optical module through an MDIO bus. The source end may have a plurality of source end devices, but each source end device is connected to a source end optical module through a low-speed management interface. The source end may also have only one source end device, but the source end device has a plurality of ports, and each port is connected to one source end optical module through the low-speed management interface.
In an embodiment, the writing of the location information of the source end device into the source end optical module connected thereto may be writing the location information of the source end device into a designated register of the source end optical module. In general, it is understood that a register is a storage unit in a CPU, and is close to the CPU, so the CPU usually uses the register as a transfer station during operation. Register function: the data in the register may be subject to arithmetic and logical operations; the address stored in the register can be used to point to a certain location of the memory, i.e. addressing; the register can be used for reading and writing data to the peripheral equipment of the computer.
In the above embodiment, the optical module redefines some register address spaces for storing the location information of the source device. If the optical module writing function is not opened by the equipment network management, the optical module connected to the equipment can complete the position information input in a terminal access and command line mode (such as a Telnet protocol).
For any source end device, a pre-configuration operation is first performed to identify configuration parameters of physical location information of the device, where the location information may include, but is not limited to, information such as a machine room address, device manufacturer information, a device name and model, a device slot, a port, and a MAC address, and the location information further includes data related to the location information.
Step S120, converting the position information and the service data to be transmitted in the source optical module into an optical signal, and sending the optical signal to a sink optical module located at a sink via an optical fiber.
The position information stored in the register of the source optical module can generate an optical signal along with all or part of service data in the register of the source optical module, and the optical signal is sent to the host optical module located at the host through the optical fiber. It can be understood that the source optical module is connected to the corresponding sink optical module through an optical fiber, and transmits an optical signal to the corresponding sink optical module through the optical fiber.
Fig. 2 schematically shows a flowchart of an embodiment of step S120, and referring to fig. 2, in step S120, converting the position information and the traffic data that needs to be transmitted in the source optical module into an optical signal at least includes steps S121 to S122.
Step S121, converting the position information into a position electrical signal, and converting the service data into a service electrical signal.
In one embodiment, the position information is converted into a position electrical signal by modulation, and the service data is converted into a service electrical signal, wherein the modulation may be converting the position information into the position electrical signal by external modulation, and the service data is converted into the service electrical signal.
In another embodiment, the position information may be converted into a position electric signal by tuning, and the corresponding position electric signal belongs to the tuning signal.
It should be noted that the modulation includes external modulation and internal modulation, the internal modulation is to change a certain parameter of laser oscillation according to the rule of the modulation signal in the laser forming process, i.e. the modulation signal controls the laser forming, the modulation is to directly modulate the light source itself by the signal to change the oscillation parameter of the laser by the modulation signal, the output characteristic of the laser is changed to realize the modulation by the change of the bias current or the change of the cavity length of the laser tube, and the loading signal is performed in the laser oscillation process. The external modulation is a method of applying a modulation signal during oscillation of laser light formation, and the modulation is realized by changing the output characteristics of the laser light, which is called as internal modulation. After the laser is formed, the laser is modulated with a modulation signal, which does not change the parameters of the laser but changes the parameters of the laser beam that has been output. The inner modulation is directly input to the laser driving circuit modulation signal to control its output. Unlike external modulation, the laser is not controlled in external modulation, and only the output laser is modulated.
Step S122, converting the combined position electrical signal and the combined service electrical signal into the optical signal.
In one embodiment, a low-speed pilot signal (i.e., a position electrical signal) generated by pilot tuning is generated along with a high-speed main service electrical signal to generate an optical signal, and the source optical module transmits the optical signal to the sink optical module through an optical fiber.
In the transmission of networks (such as SDH networks and WDM networks), each channel typically transmits traffic information, while the present application can also transmit management-related information, i.e. location information.
For the service information, it is necessary to occupy the wavelength resource, but for the location information, whether to use an independent channel resource or attach to the service information transmission needs to be distinguished according to the specific application scenario. In the embodiment, the transmission of the position information is realized in the transmission process of the main service through the top-tuning technology without using an independent wave channel. Under the condition that the wavelength resource is deficient, the wavelength resource can be effectively saved.
In the WDM network, the top-tuning technique is to superimpose a low-frequency sine or cosine modulation with a small amplitude on each wavelength at the transmitting end, and when the low-frequency sine or cosine signal is superimposed on the optical wavelength, there is a modulation amplitude at the top of the optical wavelength, so it is called a top-tuning signal. The low-speed channel associated signal based on the Pilot tone method may be called a low-frequency perturbation (low-frequency) signal, and may also be called Pilot tone modulation (Pilot tone modulation).
In the above embodiment, if different wavelength identifiers are used, the frequency of the tuning signal is detected to identify different wavelength identifiers, and the tuning signal includes a frame preamble, a frame header, and a frame trailer. And the wavelength tracking function can be realized at the sink end according to the frequency identification. It should be noted that tuning can also be used to monitor various optical parameters of the WDM signal, such as optical power, wavelength, and optical signal-to-noise ratio (OSNR). The method does not need to use expensive demultiplexing filters (such as a tunable optical filter, a diffraction grating and the like), and has the advantage of saving construction cost.
But since the main task of the optical module is to transmit traffic signals. That is, if the pilot tone signal is too strong, resulting in too large disturbance, the waveform of the traffic signal may be damaged, parameters including signal-to-noise ratio (OSNR) and extinction ratio of the traffic signal may be adversely affected, and the sensitivity of the host optical module to receive the signal may be reduced. If the strength of the tune-to-cap is not sufficient, the tune-to-cap signal may be affected by the gain dynamics and eventually filtered out. Therefore, the frequency of the set-top signal is set between 10KHz and 1MHz, so that the problem that the set-top signal is too strong or insufficient in strength can be effectively solved.
Step S130, separating the position information from the optical signal, and writing the position information into the sink device connected to the sink optical module.
In an embodiment, the sink optical module is connected to the sink device through the low-speed management interface, and the specific connection manner is the same as that in the above embodiment, and repeated description is omitted here.
Fig. 3 schematically shows a flowchart of an embodiment of step S130, and referring to fig. 3, in step S130, separating the position information packet from the optical signal at least includes steps S131 to S132.
Step S131, converting the optical signal into an electrical signal.
In one embodiment, the sink optical module converts an optical signal into an electrical signal.
Step S132, separating the position electrical signal from the electrical signal, and converting the position electrical signal into the position information.
In an embodiment, the sink optical module separates a position electrical signal from the electrical signal, converts the position electrical signal into position information, which may be the position information stored in the source optical module restored by the sink optical module, and writes the position information into the sink device through the management interface.
Fig. 4 schematically shows a block diagram of a cross-network data transmission method according to another embodiment of the present application, as shown in fig. 4, a source end and a sink end are respectively two independent management and control systems, a source end management and control system 410 and a sink end management and control system 420, a source end device 411 writes position information of a source end device into a source end optical module 412 connected thereto through a low-speed management interface, and writes position information of the source end device 411 into a specified register of the source end optical module 412, where writing the position information into the register of the source end optical module has a non-volatile advantage. All or part of the service data stored in the register of the source-end optical module 412 can selectively generate a low-speed top-modulation electric signal through a top-modulation technology, the top-modulation electric signal generates an optical signal along with a main service electric signal, the source-end optical module 412 sends the optical signal to the sink-end optical module 422 through the optical fiber 430, the sink-end optical module 422 separates the top-modulation signal from the optical signal, restores the position information of the source-end device 411, and writes the position information into the sink-end device 421 through the management interface.
Step S140, storing a path mapping relationship between the location information of the source device and the sink device, and when a failure occurs in a transmission link of the service data, locating the failure according to the path mapping relationship.
In the networking mode of the all-optical network, when an inter-domain network fails, a network manager can often analyze the failure reason through an alarm reported by local equipment (namely, host equipment), but cannot know the failure position of a far end in time when the problem of the far end (namely, source equipment) is located, which is not beneficial to failure location and rapid service recovery. Therefore, the cross-network data transmission system can solve the problem of how to sense the optical fiber connection relation between different professional networks by storing the path mapping relation of the position information of the source end equipment and the sink end equipment.
As shown in table 1 below, which is a path mapping relationship between location information of a source device and a sink device, in table 1, the source device is located at a source location, and the source location may be X1Ground Y1Machine room Z1Device number 1 port number 1Optical module with path mapping destination position X2Ground Y2Machine room Z2Device number 1 port number 1 optical module. For example, the source end position is the optical module of No. 1 device port 1 of the IP machine room No. 1 in the baean area, and the destination end position of the path mapping is the optical module of No. 1 device port 1 of the transmission machine room No. 2 device in the south and mountainous areas. The source position may also be X1Ground Y1Machine room Z1The destination end position of the path mapping of the optical module No. 2 port of the equipment is X2Ground Y2Machine room Z2Device number 2 port number 2 optical module. For example, the source end position is the optical module of the IP machine room No. 1 device No. 2 port No. 2 in the baean area, and the destination end position of the path mapping is the optical module of the transmission machine room No. 2 device No. 2 port No. 2 in the south and mountainous areas. As can be seen from the above two examples, the source end position and the sink end position respectively belong to a mapping relationship in which one device has multiple ports, and then the mapping relationship in which the source end position and the sink end position respectively have multiple devices is described.
The source position may be X3Ground Y3Machine room M3The number 1 port of the number 1 optical module of the equipment has a path mapping destination end position of X4Ground Y4Machine room M4Device number 1 port number 1 optical module. For example, the source end position is the optical module of the IP machine room No. 3 device No. 1 port No. 1 in the baean area, and the destination end position of the path mapping is the optical module of the transmission machine room No. 4 device No. 1 port No. 1 in the south and mountainous areas. The source position may also be X3Ground Y3Computer lab N3The number 1 port of the number 1 optical module of the equipment has a path mapping destination end position of X4Ground Y4Computer lab N4Device number 1 port number 1 optical module. For example, the source end position is the optical module of the device No. 1 port No. 3 of the IP machine room in the bright area, and the destination end position of the path mapping is the optical module of the device No. 1 port No. 4 of the transmission machine room in the plateau and mountain area.
It should be noted that an IP room is generally used for IP management and control and analysis, if a fault occurs, the whole telecommunication network cannot be used, and a transmission room belongs to a room of a telecommunication incoming line and is generally used for distribution networks in other places.
Table 1 path mapping relationship of location information of source device and sink device
In an embodiment, after writing the location information to the sink device connected to the sink optical module, the method further includes: storing the position information on the host equipment, and setting a survival time value corresponding to the position information; determining whether the storage time length of the position information on the sink end equipment reaches the survival time value; and if the storage time of the position information on the host equipment reaches the survival time value, updating the position information.
By setting a Time To Live (TTL) value, location information stored by the sink device can be intermittently updated, for example, when the time length for storing the location information on the sink device reaches the TTL value, that is, the TTL is equal to 0, the sink device will update the location information of the source device, that is, the path mapping relationship will also be updated.
It can be understood that the path mapping relationship between the source end device and the sink end device may also be updated in real time, that is, the source end optical module and the sink end optical module continuously send the position information.
It should be noted that the time-to-live refers to the time of persistence of a domain name resolution record in the server. When servers in various places receive the resolution request, the resolution request is sent to an authoritative domain name server appointed by the domain name so as to obtain a resolution record; after obtaining the record, the record will be stored in the cache servers (also called recursive domain name servers) at various places for a period of time, and if receiving the resolution request of the domain name again in the period of time, the servers at various places will not send the request to the authoritative domain name server any more, but directly return to the record obtained just before; and the time that this record remains on the server is the TTL value.
In an embodiment, the method further comprises: and if the optical module is switched to be connected with other source end equipment at the source end, updating the position information into the position information of the other source end equipment.
The optical module is switched to be connected with other source end devices at the source end, that is, when the path mapping relationship between the source end device and the sink end device changes, the sink end device position information is updated to the position information of the other source end devices, that is, the path mapping relationship between the source end device and the sink end device is also updated. For example, the path mapping relationship between the source device and the sink device is the source device No. 1 and the sink device No. 2, and when the source optical module is switched from the source device No. 1 to the source device No. 3, the path mapping relationship between the source device and the sink device is updated to the source device No. 3 and the sink device No. 2.
