Wherein, the optical transport network cluster may be a cluster providing an optical transport server, and may include optical network elements connected together by optical fiber links, and the optical transport network cluster may include only a single optical transport device; the target upgrade attribute may be a cluster attribute after the optical transport network cluster is upgraded, and the target upgrade attribute may be recorded in the optical transport network cluster and may identify a current attribute state of the optical transport network cluster, for example, the target upgrade attribute may include a data transport manner, a data processing manner, and the like of a cross board, and specifically may be a character string composed of characters, letters, numbers, and special symbols; the target upgrading type may be an optical transport network cluster type after the optical transport network cluster is upgraded, the target upgrading type may be obtained through user input, and the target upgrading type may include a blocked three-level optical transport network cluster, an unimpeded three-level optical transport network cluster, and the like.
Specifically, before the optical transport network cluster is upgraded, a target upgrade attribute and a target upgrade type of the optical transport network may be requested to be obtained, and a user may input the corresponding target upgrade attribute and the target upgrade type according to a service requirement.

And 103, adding an optical module in a cross board of the optical transport network cluster according to the target upgrading type.
The cross board can be a hardware device for data exchange in the optical transport network cluster, the optical transport network cluster is a single-stage optical transport network cluster before upgrading, the exchange board can realize data exchange through a serializer and/or a deserializer, and the data transmission efficiency is low; the optical module may be a hardware device that implements optical fiber link connection, and may perform interconversion between electrical signals and optical signals, and the optical module may include components such as an optoelectronic device, a functional circuit, and an optical interface.
Specifically, different target upgrade types may be different in ways of adding an optical module in an optical transport network cluster, the target upgrade types and the ways of adding an optical module may be stored in advance, and when a target upgrade type is obtained, an optical module may be added to the optical transport network cluster according to different target upgrade types, for example, if the target upgrade type is a blocking three-stage optical transport cluster, the optical module may be half-connected to the optical transport network cluster, so that the optical module does not perform data transmission at full power, and if the target upgrade type is a blocking three-stage optical transport cluster, the optical module may be full-connected to the optical transport network cluster, so that the optical module performs data transmission at full power.
And 104, configuring a transmission routing table corresponding to the target upgrading type on the service board of the optical transport network cluster after the optical module is added so as to complete upgrading of the optical transport network cluster.
The service board may be a hardware device performing data exchange operation in the optical transport network cluster, the service board may be located in a service frame of the optical transport network cluster, and data in the optical transport network cluster may be transmitted according to a transmission routing table in the service board; the transmission routing table may be a basis for data exchange in the optical transport network, the transmission routing table may include transmission links from a current service board to a target service board, the transmission routing table may correspond to the service boards, and each service board may store a corresponding transmission routing table.
In the embodiment of the present invention, a transmission routing table may be configured for an optical transmission network cluster, and because the generation manners of the transmission routing tables corresponding to different target upgrade types are different, the generation manner of the transmission routing table may be determined according to the target upgrade type and the transmission routing table may be generated according to the corresponding generation manner, for example, the target upgrade type is; the transmission routing table may be configured to each service board of the optical transport network cluster, and the optical transport network cluster may determine to complete upgrading of the optical transport network cluster after completing configuring the transmission routing table.
The technical scheme of the embodiment of the invention updates the cluster cross attribute of the optical transport network cluster according to the target upgrading attribute by acquiring the target upgrading attribute and the target upgrading type of the optical transport network cluster, adds the newly-added service frame and the newly-added center frame in the optical transport cluster, adds the optical module into the optical transport network cluster according to the target upgrading type, configures a transmission routing table corresponding to the target upgrading type for each service board of the optical transport network cluster, realizes the smooth upgrading of the optical transport network, reduces the influence of the upgrading process on user services, improves the availability of the optical transport network cluster, determines the target upgrading attribute and the target upgrading type according to the cost, and can reduce the success of upgrading.
Example two
Fig. 3 is a flowchart of an optical transport network cluster upgrading method provided in the second embodiment of the present application, which is embodied based on the foregoing embodiment, and referring to fig. 3, the method for upgrading an optical transport network cluster in the second embodiment of the present application includes:
Specifically, because the cost of the unobstructed three-level optical transport network cluster is too high, a user can determine whether to upgrade the optical transport network cluster to the unobstructed three-level optical transport network cluster or to upgrade to the obstructed three-level optical transport network cluster according to the service requirement of the user, and after the user upgrades the target of the optical transport network cluster, the target upgrade attribute and the target upgrade type of the user upgraded optical transport network cluster can be obtained, and the target upgrade attribute and the target upgrade type can be actively input by the user or determined by evaluating the width resource of the optical transport network cluster.
Specifically, after the optical transport cluster modifies the cluster crossing attribute according to the target upgrade attribute, the newly added service frame and the newly added center frame may be connected to the optical transport network cluster, and the newly added service frame and the newly added center frame may be powered on after the connection is successful, so that the newly added service frame and the newly added center frame work normally in the optical transport network cluster.
And 203, taking the cross boards without the added optical modules in the optical transport network cluster as target cross boards one by one.
The cross board can be a hardware device for exchanging data between the service frame and the central frame in the optical transport network cluster, and the cross board does not include an optical module before being upgraded, so that the data exchange efficiency is low; the target cross board may be a cross board for performing an operation of adding an optical module, and the operation of adding an optical module may be performed only on one target cross board at a time in the optical transport network cluster.
In the embodiment of the present invention, a cross board may be selected in the optical transport network cluster as a target cross board to which an optical module is added, and the cross board selected as the target cross board may be a cross board to which the optical module is not added.
And 204, taking the target cross board off line from the optical transport network cluster.
The off-line may mean that other cross boards of the optical transport network do not send data to the target cross board any more.
Specifically, a jog button of the target cross board may be triggered, and after the service board in the optical transport network cluster acquires a signal of the jog button, data may not be sent to the target cross board any more. Fig. 4 is a schematic structural diagram of redundancy protection of an optical transport network cluster according to a second embodiment of the present application, and referring to fig. 4, because a transmission link between a service board and a cross board in the optical transport network cluster has a redundancy design, when a target cross board is offline from the optical transport network cluster, the transmission link between the remaining cross board and the service board can still carry an original service, so that service loss during the offline process of the target cross board is realized.
Further, the taking the target cross board off-line from the optical transport network cluster includes:
after determining the offline request of the target cross board, sending an offline message to the cross board to be notified; and sending the offline message to a service board connected with the cross board to be notified through the cross board to be notified so as to prohibit sending data to a target cross board.
Wherein the offline request may be a request for an offline target cross board, for example, may be a request for activation of a micro-switch on the target cross board; the offline message may be a message for notifying the service board in the optical transport network cluster that the data is no longer sent to the target cross board; the cross board to be notified may be a cross board located at the same position as the target cross board, the target cross board may not belong to the same service frame as the cross board to be notified, and the cross board to be notified may send the offline message to the target cross board; the service board can exchange data with the target cross board.
In the embodiment of the present invention, after determining that the offline request of the target cross board is obtained, the offline message may be sent to all service boards connected to the target cross board, the target cross board may be connected to the service board through the cross board to be notified, the offline message is sent to the service board through the cross board to be notified, the service board may be notified that the service board does not send data to the target cross board any more, and the offline of the target cross board is achieved through the offline message.
And step 205, adding an optical module in the target cross board according to the target upgrading type after determining that the optical transport network cluster does not send data to the target cross board any more.
In the embodiment of the present invention, before adding an optical module to a target cross board, it is necessary to determine that the target cross board has been successfully offline in an optical transport network cluster, and the optical transport network cluster may no longer send data to the target cross board as a sign that the target cross board is successfully offline, for example, an indicator lamp may be disposed on the target cross board, and when the target cross board no longer receives the data, the indicator lamp may be turned on to represent that the target cross board is successfully offline. After the target cross board is determined to be offline successfully, adding the optical module in the target cross board does not affect the service operation of the optical transport network cluster, and the optical module of the target cross board can be connected according to the target upgrading type because the target upgrading type of the optical transport network cluster corresponds to different optical module connection modes.
Further, adding an optical module in the target cross board according to the target upgrade type includes:
when the target upgrading type is a three-level optical transport network cluster with resistance, connecting the switching chips with threshold number in the target cross board with the optical modules, setting the switching chips connected with the optical modules to be in a cascaded three-level mode, and setting the switching chips not connected with the optical modules to be in a single-level mode; and when the target upgrading type is the unobstructed three-level optical transport network cluster, connecting all the switching chips in the target cross board with the optical module, and setting the switching chips to be in a cascade three-level mode.
The optical modules configured in the optical transport network clusters with the three levels of resistance do not run at full power, cross boards in the optical transport network clusters with the three levels of resistance are not all connected with each other, and data cannot arrive by any transmission link when being sent in the optical transport network clusters with the three levels of resistance; the resistless three-level optical transport network cluster is a cluster for transmitting data based on optical links, optical modules configured in the resistless three-level optical transport network cluster run at full power, cross plates in the resistless three-level optical transport network cluster are all connected with each other, and data can arrive by any transmission link when being transmitted in the resistless three-level optical transport network cluster; the switching chip may be a chip for data exchange on the optical transport network cluster cross board, and the switching chip may be connected to the optical module.
Specifically, if the target upgrade type of the otn cluster is a blocked three-stage otn cluster, the switching chips with the threshold number selected in the target cross board may be connected to the optical module, where the threshold number may be a preset number, for example, half of the number of the switching chips in the target cross board, the switching chips connected to the optical module in the target cross board may be set to be in a cascaded three-stage mode, and the remaining switching chips not connected to the optical module are set to be in a single-stage mode; if the target upgrading type of the optical transport network cluster is the unobstructed three-level optical transport network cluster, all the switch chips in the target cross board can be connected with the optical module, and after the connection, the switch chips can be set to be in a cascade three-level mode.
And step 206, acquiring data packets corresponding to each transmission link of the service board in the optical transport network cluster.
The service board may be a hardware device for sending data in the optical transport network cluster, the service board may be connected to other service boards in the optical transport network cluster through a transmission link, the transmission link may include a cross board and an optical module, and data in the transmission link is transmitted in the form of a data packet.
Specifically, for each service board in the optical transport network cluster, a corresponding data packet is obtained, where the data packet may be a data packet transmitted through different transmission links, for example, the data packet may be labeled for a transmission link of the service board, and the data packet transmitted through different transmission links may include a label of the corresponding transmission link.
The timestamp can be information used for identifying the clock of the optical transport network, which is generated when the service board sends the data packet, because the lengths of the transmission links in the optical transport network cluster are different, the transmission speeds of the data packet at the transmission links are different, the timestamps of the data packet received by the service board may not be synchronous, and in order to ensure the consistency of the data packet processed by the service board, the transmission links need to be controlled so that the timestamps of the data packet processed by the service board are consistent.
In the embodiment of the present invention, when a service board of an optical transport network cluster acquires a data packet, a timestamp of each data packet may be acquired, and if the timestamp of the data packet is inconsistent with the timestamps of other data packets, the length of a transmission link through which the data packet passes is different from the lengths of other transmission links, which may control the transmission link.
Specifically, the transmission routing tables configured for the service boards in the optical transport network clusters of different target upgrade types are different, when the target upgrade type is a non-blocking three-level optical transport network cluster, the unicast routing tables of each service board can be directly obtained, the unicast routing tables are subjected to the same operation to obtain the same routing table information, the routing table information is stored as the transmission routing table, when the target upgrade type is a blocking three-level optical transport network cluster, the service carried by the service boards in the optical transport network cluster needs bidirectional data transmission, in the blocking three-level optical transport network cluster, when the service boards realize data interaction across the service frames, the data interaction is actually realized only through a part of transmission links, if only the unicast routing tables are used to generate the transmission routing tables, the traffic of the service boards in the corresponding service frames may be damaged, and the traffic transmission in the corresponding service frames can only reach the traffic bandwidth across the service frames, and one more multicast routing table can be generated to realize the traffic transmission of the cross service frame.
Further, when the target upgrade type is a blocked three-level optical transport network cluster, a local unicast routing table corresponding to each service frame is acquired for the service frames in the optical transport network cluster, the same routing information in each local unicast routing table is stored as a multicast routing table, and the multicast routing table is configured to each service board as a transmission routing table.
The unicast routing table of this frame may be a routing table used by the service board for performing data transmission in the service frame to which the service board belongs, and the unicast routing table of this frame may be generated according to an initial routing generation rule, for example, when a data packet in the service frame to which the service board belongs is acquired, a transmission link and a source address of the data packet may be stored in the unicast routing table of this frame. The multicast routing table may be a routing table used by the service board for performing data interaction between service frames, and may be generated by processing a unicast routing table of a local frame of each service frame.
In the embodiment of the invention, when the target upgrading type is a blocked three-level optical transport network cluster, the frame unicast routing table corresponding to each service frame in the optical transport network cluster can be obtained, the frame unicast routing table can be stored in the respective service board of the service frame, the frame unicast routing table of one service board can be randomly obtained for each service frame, the obtained unicast routing table of each frame can be subjected to AND operation, all the same routing information in the unicast routing table of each frame can be obtained and stored as a multicast routing table, for example, the present unicast routing table a stores three pieces of routing information, a1, a2, and a3, the present unicast routing table B stores two pieces of routing information, a1 and B1, the present unicast routing table C stores two pieces of routing information, a1 and C2, the same routing information in the present unicast routing tables A, B and C is a1, and a1 may be stored as a multicast routing table. After the multicast routing table is obtained, the multicast routing table may be configured as a transmission routing table to a service board of each service frame in the optical transport network cluster, and when the service board sends data that spans the service frames, data transmission may be performed by depending on the multicast routing table.
The technical proposal of the embodiment of the invention obtains the target upgrading attribute and the target upgrading type of the optical transport network cluster, updating the cluster crossing attribute of the optical transport network cluster according to the target upgrading attribute, connecting the newly added service frame and the newly added center frame into the optical transport network cluster, taking the cross boards without the added optical modules as target cross boards one by one, taking the target cross boards off line and adding the optical modules in the target cross boards, synchronously controlling the data packets according to the transmission link to ensure that the time stamps of the data packets processed by each optical transport network cluster service board are consistent, the method and the device have the advantages that the transmission routing table is configured for the service board according to the target upgrading type, smooth upgrading of the optical transport network cluster is achieved, the influence of the upgrading process on user services is reduced, the usability of the optical transport network is improved, the target upgrading type and the target upgrading attribute are determined based on user requirements, and the upgrading cost of the optical transport network cluster is reduced on the premise of increasing the flow bandwidth.
Further, on the basis of the above embodiment of the present invention, the position of the cross board to be notified in the belonging business frame is the same as the position of the target cross board in the belonging business frame.
In the embodiment of the invention, when the target cross board in the optical transport network cluster is offline, the optical transport network cluster which is not upgraded is not finished, the target cross board can only be connected with the cross board in the service frame to which the target cross board belongs, the communication with the cross board of the cross service frame needs to pass through the cross board of the central frame, when the target cross board is off-line, the cross board to be notified of the cross service frame cannot actively sense that the target cross board is off-line, the cross board to be notified needs to acquire an off-line message and realize the off-line of the target cross board, the cross board to be notified can have the same position as the target cross board, that is, the position of the cross board to be notified in the corresponding service frame is the same as the position of the target cross board in the corresponding service frame, for example, the target cross board is a cross board at an X slot of the I-th service frame in the optical transport network cluster, and the cross board to be notified may be a cross board at an X slot of other I-1 service frames in the optical transport network cluster.
