Background technique

The OXC (Optical Cross-connect) device is a multi-functional OTN (Optical Transport Network) transmission device that combines multiplexing, wiring, protection/recovery, monitoring, and network management. The basic use of optical cross-devices in the network is to conduct automated traffic grooming with a focus on the network. With the network scale and network protection/recovery strategy and the gradual upgrading of network reliability, the necessity and importance of optical cross-devices become more prominent.

So far, DWDM (Dense Wavelength Division Multiplexing) has become the all-optical communication technology mainly used in long-distance and metropolitan area network communication applications. Introducing OXC network elements in a user's growing network environment will help to flexibly use and distribute wavelengths. These new network elements can help operators reconfigure network traffic at the photonic layer to achieve optimal data transmission and recover quickly in the event of a link failure. All-optical networks will eventually discard slow and expensive opto-electrical converters, allowing future networks to operate in a faster and more economical manner.

By using an optical cross-connect device, an optical add-drop multiplexer (OADM) can select and remove a wavelength from a WDM (Wavelength Division Multiplexing) signal at a certain node of the network. Then add a new signal to the original wavelength to continue transmission to the next node. This capability greatly enhances the load management capabilities of all-optical networks.

detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the following description, the use of suffixes such as "module", "component" or "unit" for indicating an element is merely an explanation for facilitating the present invention, and has no specific meaning per se. Therefore, "module", "component" or "unit" can be used in combination.

As shown in FIG. 1 , an embodiment of the present invention provides a method for controlling an optical cross device, and the method in this embodiment includes:

Step S110, establishing a connection with the optical cross device according to the IP address of the optical cross device.

The technical solution of the embodiment can be implemented on the OTN device, and the OTN device is used as the management device to control the optical cross device. Specifically, the TCP (Transmission Control Protocol) is established through the Ethernet port communication based on the IP address of the optical cross device. Transmission Control Protocol) connections for management.

Step S120: Acquire device information of the optical cross device according to the IP address of the optical cross device.

In this embodiment, the information of an optical cross-device can be represented by an IP address. After establishing a connection with the optical cross-device, the device information of the optical cross-device can be determined by using the IP address, and no other information is needed. The method for determining the information of the optical cross device is additionally used; in this embodiment, the device information is not limited, for example, it may be the type of the device or the software and hardware information of the device.

Step S130: Send an instruction to the optical cross device according to the device information of the optical cross device.

In this embodiment, after the information of the optical cross-device is determined, the control instruction for the optical cross-device may be generated according to the device information, and the command is sent to the optical cross-device to enable the optical cross-device to execute the command to complete the light. Control of the cross device.

According to the technical solution of the embodiment, after the IP of the optical cross-device is set, the connection with the optical cross-device can be established and the information of the optical cross-device can be identified, and the optical cross-over device is not required to perform an additional adaptation function. After the information, the corresponding instruction can be issued, and the control of the optical cross device is completed by the instruction.

As shown in FIG. 2, an embodiment of the present invention provides a method for controlling an optical cross device, and the method in this embodiment includes:

Step S210: The optical cross-device is detected according to the IP address at a predetermined time interval, and when the optical cross-device responds to the detection, a connection is established with the optical cross-device.

In this embodiment, after the optical cross-connect device is connected through the Ethernet port, the function periodically sends a ping (Ping is a command under Windows, Unix, and Linux systems) packets to the optical cross-device. The IP address starts at 192.168.128.4 and is incremented by 192.168.129.4. Up to 20 optical cross-devices can be managed at the same time. The third field in which the IP is incremented indicates the subrack number, and the ping packet succeeds in two consecutive responses to establish a socket (the two programs on the network exchange data through a two-way communication connection, and one end of the connection is called a socket). . This feature updates some of the information in the preset device list:

DeviceIpDeviceIp	DeviceTypeDeviceType	socketSocket	LinkstateLinkstate
192.168.128.4192.168.128.4	DeviceADeviceA	11	OnlineOnline
192.168.129.4192.168.129.4	DeviceBDeviceB	NULLNULL	OfflineOffline
…...	…...	…...	…...

Among them, the first column represents the device IP. The second column indicates the type of device that distinguishes the optical cross device type through different ports. The third column indicates the socket value of the device. If the device successfully establishes a socket connection, the socket value is updated, and the socket value is not empty. The fourth column indicates the connection status of the device. If the device can respond to the ping packet, it is connected.

When the optical cross device fails to ping, the socket connection is closed, and the device linked list is updated to set the socket to NULL and Linkstate to offline. Finally, if the optical cross device is in the online state, the subrack number of the device is reported as the optical cross device is offline.

Step S220: Determine information about the subrack where the optical cross device is located according to the IP address of the optical cross device and the correspondence between the preset multiple IP addresses and the multiple subracks.

In this embodiment, the sub-rack of the optical cross-device is represented by the IP address, and the relationship between the multiple IP addresses and the sub-racks can be established in advance. After the connection is established, the sub-rack can be determined according to the IP address.

Further, the device type of the optical cross device is acquired when the connection is established, and the information of the micro control unit and/or the real board of the optical cross device is determined according to the device type.

In this embodiment, after the socket connection of the optical cross-connect device is successfully established, the corresponding sub-rack number of the optical cross-device is calculated according to the IP address in the device linked list, and it is determined that the corresponding optical cross-device is online, and management can be performed. Then, according to the "device type" field, the MCU (micro control unit) address of the device, the type of the real board, the hardware version of the real board, and the software version of the real board are determined.

Step S230, issuing an instruction to the optical cross device according to the device information of the optical cross device.

Step S240, detecting whether the response of the optical cross-device to the command is received within a predetermined time range, and omitting the instruction when the determination result is no.

Step S250, receiving a response of the optical cross-device to the instruction, and acquiring a callback function processing response corresponding to the optical cross-device.

In this embodiment, after the socket connection is successfully established, two sub-modules of two processing messages implemented according to the embodiment are started. The module A is responsible for processing the commands sent to the optical cross-device, and the module B is responsible for processing the packets that the optical cross-device answers and the commands that are actively reported.

CmdCodeCmdCode	CallidCallid	BoardAddrBoardAddr	CachePosCachePos	TickTick
2A102A10	0x00010x0001	11	11	5050
2A1D2A1D	0x00020x0002	11	22	5050
1A691A69	0x00030x0003	11	33	5050
1A701A70	0x00040x0004	11	44	100100
…...	…...	…...	…...	…...

Each chained optical cross device will have a list of commands, with the first column indicating the command code. The second column represents the message id, which is unique in the message list of a device. When the device answers, it can find a unique device callback function for processing. The third column is the device address, indicating the location of the current optical cross device. The fourth column is the command cursor, which indicates the position of the current optical cross device in the command list. The fifth column is the command timeout period, which will time out if the device does not answer within the specified time.

When the OTN device sends a command, the main control board saves the command code, message id, board address, and timeout time in the command list. The command content is then converted into a TL1 (a management protocol widely used in the telecommunications field) format that the optical cross-device can recognize and sent to the device via TCP communication. At the same time, the timer will poll all messages in the message list for a timeout period. If the device times out, the optical cross-device timeout error will be acknowledged.

After the optical cross-device successfully responds, the command code in the command list is obtained according to the device id in the device list, and the content in the TL1 format is converted into the content that can be recognized by the OTN device and sent to the network management.

According to the technical solution of the embodiment, an optical cross-device can be implemented, which has a main control board, for example, as shown in FIG. 3, and establishes a TCP connection through Ethernet port communication to implement management. After the connection is established, the heartbeat is detected by pinging the packet, and the crossover capability of the optical cross device and the management status of each port are set/queried through the TL1 interface. The user only needs to simply configure the device IP to establish a connection with the optical cross device, and does not require the optical cross device to perform additional adaptation functions. And can connect and manage multiple optical cross-devices from different manufacturers at the same time.

As shown in FIG. 4, an embodiment of the present invention provides an optical cross-device control apparatus. The apparatus of this embodiment includes:

The connection establishing module 410 establishes a connection with the optical cross device according to the IP address of the optical cross device.

The device information obtaining module 420 acquires device information of the optical cross device according to the IP address of the optical cross device.

The command sending module 430 issues an instruction to the optical cross device according to the device information of the optical cross device.

As shown in FIG. 5, an embodiment of the present invention provides an optical cross-device control apparatus. The apparatus of this embodiment includes:

The connection establishing module 510 detects the optical cross device according to the IP address at a predetermined time interval, and establishes a connection with the optical cross device when receiving the response of the optical cross device to the detection.

In this embodiment, the IP address of the optical cross-device and the message queue of the management command and the device queue of the management device status are first initialized. Send a ping packet to the optical cross device and try to establish a socket connection. Specifically, the message queue is cleared at initialization and the queues in the device queue are set to be broken. After the socket connection is successfully established, the login command can be sent to the optical cross-connection, and the TL1 packet sent by the optical cross-device can be received and processed. The OTN device can parse the content of the TL1 packet according to the command code of the message queue and convert it into a corresponding format report.

The device information obtaining module 520 determines the information of the subrack where the optical cross device is located according to the IP address of the optical cross device and the correspondence between the preset multiple IP addresses and the multiple subracks.

The command sending module 530 sends an instruction to the optical cross device according to the device information of the optical cross device.

The timeout processing module 540 detects whether the optical cross-device response to the command is received within a predetermined time range, and ignores the command when the determination result is no.

In this embodiment, two task timers are created, and a timer TIMER1 is used to periodically send a ping packet to all optical cross-devices, and the in-position state and the sub-rack information are updated according to the result of the ping packet. TIMER2 is used to periodically poll the status of the command list. TIMER1 periodically sends a ping packet to the optical cross device. If pinging, the status of the device linked list is updated to the connection state and the ping packet is repeatedly sent. Otherwise, the device linked list status is broken and the message list is cleared. Another timer TIMER2 periodically clears the timeout message in the message list and responds with a timeout. The flow of the two timers working together is shown in FIG. 6.

The response processing module 550 receives the response of the optical cross device to the command, and acquires a callback function corresponding to the optical cross device to process the response.

In this embodiment, the message response time can be set and the message list can be updated while the message of the OTN device is converted into the TL1 format and sent to the optical cross device.
