An Optical Transport Network (OTN) is a transport network that implements transport, multiplexing, routing, and monitoring of service signals in an optical domain, and ensures performance indexes and survivability thereof. In the current optical transport network, each device needs to configure a corresponding IP address to complete communication including management protocol and report message with the device management system.
In general, an SNMP protocol is adopted for communication between an optical transport network frame device and a device management system, where the protocol is a network management protocol based on UDP, the device management system reads and modifies configuration attributes of a device through a specified port (e.g., 161 port), and the device sends a message, such as event information and alarm information, generated on a network element to the device management system through a specified port (e.g., 162 port). Therefore, each device managed in the network needs to be assigned an IP address to communicate with the management system, so that when large-scale devices are managed, valuable IP address resources of clients are greatly consumed, and complexity of network planning and device management is increased.
In view of this, the present invention provides a system, a method, a device and a medium for managing multiple optical transport network devices by using a single IP address, which provides a technical solution for managing multiple devices by using a single IP address for an optical transport network, greatly reduces the number of IP addresses to be allocated and used for devices in a client network, simplifies network planning and management complexity in managing large-scale devices, facilitates the device management system to abstract physical devices into management objects for modeling, and introduces device frame numbers into the naming of the modeling objects for adaptive management.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention are further described in detail by the following embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
Fig. 1 is a schematic diagram illustrating a system architecture for managing multiple optical transport network devices by using a single IP address according to an embodiment of the present invention. It should be noted that the management system of this embodiment is based on the optimization of the existing otn device management system, and specifically includes a device management system 11, a gateway device 12, and one or more otns devices (in this embodiment, a plurality of otns devices are selected and respectively denoted as an otn device 13, an otn device 14, and an otn device 15).
In this embodiment, the device management system 11 only directly communicates with the gateway device 12, one port of the gateway device 12 is connected to the device management system 11, the other port is connected to the optical transport network device 13, the optical transport network device 13 is connected to the next optical transport network device 14, the optical transport network device 14 is connected to the next optical transport network device 15, and so on, all the optical transport network devices are connected in series in the chain structure.
Specifically, the gateway device 12 is configured with an IP address for SNMP communication with the device management system 11; the optical transport network device is configured with an internal IP address for communicating with the gateway device 12 to communicate with the device management system 11 through the gateway device 12.
In a preferred implementation of this embodiment, the gateway device 12 is configured with a fixed device subrack number; the optical transport network equipment generates a corresponding equipment machine frame number based on a hardware switch of the optical transport network equipment, and generates a corresponding internal IP address based on the equipment machine frame number; the equipment machine frame number, the internal IP address and the communication port number of the optical transport network equipment are in one-to-one correspondence. Namely, each optical transport network device is provided with a hardware switch, the hardware switch is read by software to generate a device subrack number Shelf _ ID, and an internal IP address is generated according to the device subrack number Shelf _ ID.
It should be noted that the equipment Shelf number Shelf _ ID of the gateway device is fixed (for example, may be fixed to 1), and the equipment Shelf numbers of other optical transport network devices may be flexibly configured, but the equipment Shelf numbers of the optical transport network devices belonging to the same gateway device may not be duplicated, so as to avoid communication confusion.
Specifically, the optical transport network equipment comprises a plurality of groups of dial switches, the on-off state of each group of dial switches is mapped into a corresponding on-off value, and the machine frame number of the equipment is calculated according to the on-off values of the plurality of groups of dial switches; and setting the last part of the internal IP address of the optical transport network equipment according to the equipment machine frame number. For example, each hardware dial switch is composed of 5 groups of independent switch switches, each switch has two switch states, the software reads the switch states and respectively maps the switch states into values 0 and 1, the values of the 5 groups of switch switches are read and the corresponding equipment machine frame number Shelf _ ID is calculated, and meanwhile, based on the calculated Shelf _ ID value, the last part of the internal IP address is set according to the equipment machine frame number Shelf _ ID and is used for internal communication between the equipment. The corresponding calculation table is as follows:
table 1: calculating Shelf _ ID value and internal IP corresponding table according to dial switch
As can be seen from table 1, the software calculates the number Shelf _ ID of the corresponding equipment subrack by reading the Switch value, for example: the read values of Switch 1-Switch 5 are 0,0,0,1,1, respectively, and the number Shelf _ ID of the corresponding equipment subrack is 3 (2)0+21). The last part of the internal IP address is set according to the calculated Shelf _ ID, if the Shelf _ ID value is 0, the internal IP address is reserved and not used, if the Shelf _ ID value is 1, the internal IP address is fixedly distributed to the gateway equipment, and Shelf _ ID values of other equipment machine frames can be set to be values between 2 and 31 at will, so that a very flexible mechanism is provided for expansion and change of a corresponding system.
In this embodiment, since only the gateway device is directly connected to the device management system, and the other optical transport network devices are indirectly connected to the device management system, only the gateway device needs to configure an IP address for communicating with the device management system, and the optical transport network device configures an internal IP address for communicating with the gateway device, and forwards a communication message between the other device and the management system by the gateway device. The specific communication mechanism is as follows:
1) SNMP communication between the gateway device and the device management system uses the 161 port, i.e. the device management system reads and modifies the configuration attributes of the device through the 161 port.
2) The SNMP communication IP addresses between the otn device and the device management system all adopt the IP address of the gateway device, and the communication ports correspond to the serial number Shelf _ ID of the device frame one by one, as shown in table 2. The gateway device forwards the SNMP message received by a specific port (e.g., the 161 port) to the device 161 port corresponding to the corresponding internal IP address according to the correspondence in table 2.
Table 2: shelf _ ID and internal IP and SNMP communication port corresponding table
3) When the optical transport network equipment reports a message (such as event information or alarm information generated on a network element), the reported message adopts a port 162, the gateway equipment only needs to modify a source IP address in the source message into a self address and forward the self address to the equipment management system, and a Shelf _ ID field is introduced into a format of the reported message, so that the equipment management system can determine which equipment machine frame the reported message specifically comes from through the Shelf _ ID field. Specifically, the message format is shown in table 3 below:
table 3: device reporting information format
| Shelf_ID | Message header | Message body |
In a preferred implementation manner of this embodiment, the gateway device forwards communication information between other optical transport network devices and the device management system, the message forwarding process includes an SNMP message forwarding processing process and a device report message forwarding processing process, and the forwarding mechanism defines a rule in the post output chain to modify and complete forwarding of the content of the forwarded message packet based on the iptables function of linux.
In the process of message distribution, after receiving the message distributed by the device management system, the gateway device queries corresponding internal IP address information according to the target port number information in the distributed message, and forwards the distributed message to corresponding optical transport network devices. After receiving the SNMP message sent by the device management system, the gateway device queries the corresponding relation with the internal IP address according to the SNMP communication port number, modifies the destination address into the internal IP address, modifies the port number into a 161 port, and forwards the message to the corresponding device for processing.
Taking the SNMP message forwarding processing flow shown in fig. 2A as an example, the device management system (IP address is 192.168.21.8) communicates with the gateway device (IP address is 192.168.21.7, internal IP address is 1.1.1.1), the gateway device is connected to the device 2 (internal IP address is 1.1.1.2), and the device 2 is connected to the device 3 (internal IP address is 1.1.1.3). If the gateway device receives a message from the SNMP communication port with the port number 16102, the gateway device forwards the received message to the port 161 of the optical transport network device with the internal IP address 1.1.1.2 according to the correspondence between the SNMP communication port number and the internal IP address; if the gateway device receives a message from the SNMP communication port with the port number 16103, the gateway device forwards the received message to the port 161 of the optical transport network with the internal IP address 1.1.1.3 according to the correspondence between the SNMP communication port number and the internal IP address.
In the process of reporting the message, after the gateway equipment receives the information reported by the optical transport network equipment, the source IP address in the reported message is modified into the IP address of the gateway equipment, and the message is reported to the equipment management system after the equipment machine frame number corresponding to the source IP address is introduced into the reported message. Namely, after receiving the report message of other devices, the gateway device modifies the source IP address in the message packet and forwards the message to the device management system, wherein the report message includes the device machine frame number Shelf _ ID field, and the device management system determines which device machine frame the report message specifically comes from according to the information of the field.
Taking the SNMP message reporting processing flow shown in fig. 2B as an example, the device management system (IP address is 192.168.21.8) communicates with the gateway device (IP address is 192.168.21.7, internal IP address is 1.1.1.1) through the router, the gateway device is connected to the device 2 (internal IP address is 1.1.1.2), and the device 2 is connected to the device 3 (internal IP address is 1.1.1.3). If the otn device reports a message using 162 port, for example, device 2 (internal IP address is 1.1.1.2) reports a message, the gateway device modifies the source IP address in the source message to its own IP address 192.168.21.7, introduces Shelf _ ID field in the format of the report message, and forwards the message to the device management system; for example, the device 3 (the internal IP address is 1.1.1.3) reports the message, the gateway device modifies the source IP address in the source message to its own IP address 192.168.21.7, introduces the Shelf _ ID field in the format of the report message, and forwards the message to the device management system.
In a preferred implementation of this embodiment, the device management system abstracts and models physical devices into management objects, including but not limited to devices, subracks, channels, boards, or ports, etc. Aiming at the condition that a single IP address manages a plurality of optical transport network devices, a machine frame number is introduced into the name of a modeling object for adaptation, so that the management object corresponds to the physical device one by one. Wherein, the shelf represents the frame id, the slotid represents the channel id, the cardtype represents the board type, the port id represents the port id, and the naming rule of the management object is specifically as shown in the following table 4:
table 4: naming rules for managing objects
Before the equipment management system issues the SNMP message, according to the mapping relation between the equipment machine frame number Shelf _ ID and the communication port, the destination address of the SNMP message is set as gateway equipment, the destination port is set as a corresponding port, and as described above, the gateway equipment forwards the message to the corresponding equipment machine frame; when the equipment management system receives the report message sent by the gateway equipment, the specific equipment machine frame for reporting the message is determined to carry out corresponding processing according to the Shelf _ ID field in the message.
As can be seen from the above, the system for managing multiple optical transport network devices by using a single IP address provided in this embodiment greatly reduces the number of IP addresses that need to be allocated to devices in a client network, simplifies network planning and management complexity in managing large-scale devices, and facilitates the device management system to abstract physical devices into a management object for modeling, and introduces a device machine frame number into the naming of the modeling object for adaptive management.
Example two
Fig. 3 is a schematic flow chart illustrating a method for managing multiple optical transport network devices by using a single IP address according to an embodiment of the present invention. The method provided by the present embodiment includes steps S31 and S32, which are applied to a gateway device in a system in which a single IP address manages a plurality of optical transport network devices.
Step S31: an IP address is configured for communication with a device management system.
Step S32: and communicating with the optical transport network equipment based on the internal IP address configured by the optical transport network equipment so as to forward the information issued by the equipment management system to the corresponding optical transport network equipment and transmit the information reported by the optical transport network equipment to the equipment management system.
Specifically, the gateway device is configured with a fixed device subrack number; the optical transport network equipment generates a corresponding equipment machine frame number based on a hardware switch of the optical transport network equipment, and generates a corresponding internal IP address based on the equipment machine frame number; the optical transport network equipment comprises an optical transport network equipment frame, an internal IP address and an SNMP port number, wherein the equipment frame number, the internal IP address and the SNMP port number of the optical transport network equipment correspond to one another one to one.
After receiving the message issued by the device management system, inquiring corresponding internal IP address information according to the target port number information in the issued message, and forwarding the issued message to corresponding optical transport network equipment. After receiving the SNMP message sent by the device management system, the gateway device queries the corresponding relationship with the internal IP address according to the SNMP port number, modifies the destination address to the internal IP address, modifies the port number (for example, 161 port), and forwards the message to the corresponding device for processing.
