The method can upgrade the single-stage optical transmission network to the three-stage optical transmission network with resistance or the three-stage optical transmission network without resistance, reduce the influence of the upgrade process on the service and improve the usability of the network.
Example 1
Fig. 2 is a flowchart of an optical transport network cluster upgrading method provided in the first embodiment of the present application, where the embodiment is applicable to a situation of an upgraded single-stage optical transport network cluster, the method may be performed by an optical transport network cluster upgrading device, and the device may be implemented in a hardware and/or software manner, and referring to fig. 2, the method in the embodiment of the present application specifically includes the following steps:
Step 101, obtaining a target upgrade attribute and a target upgrade type of the optical transport network cluster.
The optical transport network cluster may be a cluster for providing an optical transport server, may include optical network elements connected together by optical fiber links, and may include only a single optical transport device; the target upgrade attribute may be a cluster attribute of an optical transport network cluster after upgrade, 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 transmission mode, a data processing mode, and the like of a cross board, and may specifically be a character string formed by characters, letters, numbers, and special symbols; the target upgrade type can be an optical transport network cluster type after the optical transport network cluster is upgraded, the target upgrade type can be obtained through user input, and the target upgrade type can comprise a resistive three-level optical transport network cluster, an unimpeded three-level optical transport network cluster and the like.
Specifically, before starting to upgrade the optical transport network cluster, the user may request to obtain a target upgrade attribute and a target upgrade type of the optical transport network, and input the corresponding target upgrade attribute and target upgrade type according to service requirements.
Step 102, updating the cluster cross attribute of the optical transport network cluster to the target upgrade attribute, and adding a new service frame and a new center frame into the optical transport network cluster.
The cluster cross attribute may be attribute information of cross transmission data in the optical transport network cluster, for example, may include cross transmission data in a service frame, cross transmission data across the service frame, and the like, and the cluster cross attribute may be set in the optical transport network cluster, and may be modified according to a target upgrade attribute when upgrading the optical transport network cluster; the newly added service frame and the newly added center frame may be hardware devices added to increase the data transmission capacity of the optical transport network cluster, so as to improve the data transmission capacity of the optical transport network cluster.
In the embodiment of the invention, the cluster cross attribute of the optical transport network cluster to be upgraded can be changed into the target upgrade attribute according to the acquired target upgrade attribute, for example, the cluster cross attribute of the optical transport network cluster before upgrading is a single-stage cross cluster, the target upgrade attribute is an unimpeded three-stage cluster, and the cluster cross attribute in the optical transport network cluster can be replaced by the unimpeded three-stage cluster; after the optical transport cluster modifies the cross attribute of the cluster according to the target upgrading attribute, the newly-added service frame and the newly-added center frame can be connected into the optical transport network cluster, and after the connection is successful, the newly-added service frame and the newly-added center frame can be powered on, so that the newly-added service frame and the newly-added center frame work normally in the optical transport network cluster.
And step 103, adding optical modules in the cross boards of the optical transport network cluster according to the target upgrading type.
The cross board can be hardware equipment for data exchange in the optical transport network cluster, the optical transport network cluster is a single-stage optical transport network cluster before upgrading, and the exchange board can realize data exchange through the serializer and/or the deserializer, so that the data transmission efficiency is lower; the optical module can be a hardware device for realizing optical fiber link connection, can mutually convert electric signals and optical signals, and can comprise an optoelectronic device, a functional circuit, an optical interface and other components.
Specifically, different target upgrade types may have different ways of adding the optical module in the optical transport network cluster, the target upgrade types and the ways of adding the optical module may be stored in advance, when the target upgrade types are obtained, the optical module may be added to the optical transport network cluster according to the different target upgrade types, for example, if the target upgrade types are resistive three-level optical transport clusters, the optical module may be semi-connected to the optical transport network cluster, so that the optical module does not perform data transmission with full power, and if the target upgrade types are non-resistive three-level optical transport clusters, the optical module may be fully connected to the optical transport network cluster, so that the optical module performs data transmission with full power.
And 104, configuring a transmission routing table corresponding to the target upgrading type by the service board of the optical transport network cluster after the optical module is added so as to finish the upgrading of the optical transport network cluster.
The service board can be a hardware device for executing data exchange operation in the optical transport network cluster, the service board can be located in a service frame of the optical transport network cluster, and data in the optical transport network cluster can 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, and the transmission routing table may include a transmission link from the current service board to the target service board, where the transmission routing table may correspond to the service boards, and each service board may store the corresponding transmission routing table.
In the embodiment of the invention, a transmission routing table can be configured for an optical transmission network cluster, and because the generation modes of the transmission routing tables corresponding to different target upgrading types are different, the generation modes of the transmission routing tables can be determined according to the target upgrading types and the transmission routing tables can be generated according to the corresponding generation modes, for example, the target upgrading types are as follows; the transmission routing table can be configured to each service board of the optical transport network cluster, and after the optical transport network cluster is configured to complete the transmission routing table, the completion of the upgrade of the optical transport network cluster can be determined.
According to the technical scheme of the embodiment of the invention, the target upgrading attribute and the target upgrading type of the optical transport network cluster are obtained, the cluster intersection attribute of the optical transport network cluster is updated according to the target upgrading attribute, the newly-added service frame and the newly-added center frame are added in the optical transport network cluster, the optical module is added into the optical transport network cluster according to the target upgrading type, the transmission routing table corresponding to the target upgrading type is configured for each service board of the optical transport network cluster, smooth upgrading of the optical transport network is realized, the influence of the upgrading process on user service is reduced, the availability of the optical transport network cluster is improved, the target upgrading attribute and the target upgrading type are determined according to the cost, and the upgrading success can be reduced.
Example two
Fig. 3 is a flowchart of an optical transport network cluster upgrade method according to a second embodiment of the present application, where the embodiment of the present application is embodied based on the foregoing embodiment, and referring to fig. 3, the optical transport network cluster upgrade method according to the embodiment of the present application includes:
step 201, obtaining a target upgrade attribute and a target upgrade type of an optical transport network cluster.
Specifically, because the cost of the non-blocking three-level optical transport network cluster is too high, a user can determine whether to upgrade the optical transport network cluster to the non-blocking three-level optical transport network cluster or to the blocking three-level optical transport network cluster according to own service requirements, after the user upgrades the target of the optical transport network cluster, the target upgrading attribute and the target upgrading type of the user upgraded optical transport network cluster can be obtained, and the target upgrading attribute and the target upgrading type can be actively input by the user or can be determined by evaluating the width resource of the optical transport network cluster.
Step 202, updating the cluster cross attribute of the optical transport network cluster to the target upgrade attribute, and adding a new service frame and a new center frame into the optical transport network cluster.
Specifically, after the optical transport cluster modifies the cross attribute of the cluster according to the target upgrade attribute, the newly-added service frame and the newly-added center frame can be connected to the optical transport network cluster, and after the connection is successful, the newly-added service frame and the newly-added center frame can be powered on, 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 optical modules as target cross boards one by one.
The cross board can be hardware equipment for exchanging data between a service frame and a center frame in the optical transport network cluster, and the cross board before upgrading does not comprise an optical module, so that the data exchange efficiency is low; the target cross boards may be cross boards that perform operations for adding optical modules, and only one target cross board may perform operations for adding optical modules at a time in the optical transport network cluster.
In the embodiment of the invention, the cross board can be selected from the optical transport network cluster as the target cross board for adding the optical module, and the selected target cross board can be the cross board without adding the optical module.
Step 204, taking the target cross board off-line from the optical transport network cluster.
Offline may mean that other cross boards of the optical transport network no longer send data to the target cross board.
Specifically, the micro-motion button of the target cross board can be triggered, and after the service board in the optical transport network cluster acquires the signal of the micro-motion button, the service board can not send data to the target cross board. Fig. 4 is a schematic structural diagram of redundancy protection of an optical transport network cluster, which is provided in the second embodiment of the present application, referring to fig. 4, because there is a redundancy design of a transmission link between a service board and a cross board in the optical transport network cluster, after 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 bear an original service, so as to realize service lossless of the offline process of the target cross board.
Further, the taking the target cross board offline 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 inhibit sending data to the target cross board.
The offline request may be a request for offline target cross board, for example, may be a trigger request of a micro switch on the target cross board; the offline message may be a message for notifying the service board that data is no longer sent to the target cross board within the optical transport network cluster; the to-be-notified cross board can be a cross board which is positioned at the same position as the target cross board, the target cross board and the to-be-notified cross board do not belong to the same service frame, and the to-be-notified cross board can send an offline message to the target cross board; the service board may exchange data with the target cross board.
In the embodiment of the invention, after the offline request of the target cross board is obtained, the offline message can be sent to all the service boards connected with the target cross board, the target cross board can 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 can be notified not to send data to the target cross board any more, and the offline of the target cross board is realized through the offline message.
Step 205, after determining that the optical transport network cluster does not send data to the target cross board any more, adding an optical module in the target cross board according to the target upgrade type.
In the embodiment of the invention, before the optical module is added to the target cross board, it needs to be determined that the target cross board has succeeded in offline in the optical transport network cluster, and the optical transport network cluster can no longer send data to the target cross board as a sign of successful offline of the target cross board. After the offline success of the target cross board is determined, the service operation of the optical transport network cluster is not affected by adding the optical modules into the target cross board, and the optical modules 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 blocked three-level optical transmission network cluster, connecting a threshold number of exchange chips in the target cross board with the optical modules, setting the exchange chips connected with the optical modules into a cascade three-level mode, and setting the exchange chips not connected with the optical modules into a single-level mode; when the target upgrading type is an unimpeded three-stage optical transmission network cluster, all the exchange chips in the target cross board are connected with the optical module, and the exchange chips are set to be in a cascade three-stage mode.
The optical modules configured in the blocked three-level optical transport network clusters do not operate at full power, cross boards in the blocked three-level optical transport network clusters are not all connected with each other, and data cannot be reached by any transmission link when being sent in the blocked three-level optical transport network clusters; the optical modules configured in the non-blocking three-level optical transmission network cluster run at full power, all cross boards in the non-blocking three-level optical transmission network cluster are connected with each other, and data can be reached by any transmission link when being sent in the non-blocking three-level optical transmission network cluster; the exchange chip can be used for carrying out the chip of data exchange on the optical transmission network cluster cross board, and the exchange chip can be connected with the optical module.
Specifically, if the target upgrade type of the optical transport network cluster is a blocked three-stage optical transport network cluster, a threshold number of switching chips selected from the target cross board may be connected to the optical modules, where the threshold number may be a preset number, for example, may be half of the number of switching chips in the target cross board, the switching chips connected to the optical modules in the target cross board may be set to a cascaded three-stage mode, and the remaining switching chips not connected to the optical modules are set to a single-stage mode; if the target upgrading type of the optical transport network cluster is the unimpeded three-stage optical transport network cluster, all the switching chips in the target cross board can be connected with the optical module, and the switching chips can be set to be in a cascade three-stage mode after connection.
Step 206, obtaining the 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, and may be connected to other service boards in the optical transport network cluster through a transmission link, where the transmission link may include a cross board and an optical module, and data in the transmission link is transmitted in a 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 a different transmission link, for example, the data packet may be a reference number of the transmission link of the service board, and the data packet transmitted through the different transmission link may include the reference number of the corresponding transmission link.
Step 207, if the time stamps of the data packets are different, performing synchronization control on the transmission links so that the time stamps are the same.
The time stamp may be information for identifying an optical transport network clock generated when the data packet is sent by the service board, and because the lengths of the transmission links in the optical transport network cluster are different, the transmission speeds of the data packet in the transmission links may be different, and the time stamps of the data packets received by the service board may not be synchronous, so that the consistency of the data packets processed by the service board needs to be controlled by the transmission links to ensure that the time stamps of the data packets processed by the service board are consistent.
In the embodiment of the present invention, when a service board of an optical transport network cluster obtains a data packet, a timestamp of each data packet may be obtained, if there is a timestamp of a data packet inconsistent with a timestamp of another data packet, a length of a transmission link through which the data packet passes is different from a length of another transmission link, and the transmission link may be controlled.
And step 208, configuring a transmission routing table corresponding to the target upgrading type by the service board of the optical transport network cluster after the optical module is added so as to finish the upgrading of the optical transport network cluster.
Specifically, the transmission routing tables configured by the service boards in the optical transport network clusters of different target upgrading types are different, when the target upgrading type is a non-blocking three-level optical transport network cluster, unicast routing tables of each service board can be directly obtained, the unicast routing tables are subjected to operation to obtain the same routing table information, the routing table information is stored as the transmission routing table, when the target upgrading 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, and when the service boards realize data interaction across service frames in the blocking three-level optical transport network cluster, data interaction is actually realized only through a part of transmission links, if the unicast routing tables are only used for generating the transmission routing tables, traffic of the service boards in the corresponding service frames is possibly damaged, traffic transmission in the corresponding service frames can only reach traffic bandwidth across the service frames, and one multicast traffic routing table can be generated for realizing the transmission across the service frames.
Further, when the target upgrade type is a blocked three-level optical transport network cluster, acquiring a local frame unicast routing table corresponding to each service frame for the service frame in the optical transport network cluster, storing the same routing information in each local frame unicast routing table as a multicast routing table, and configuring the multicast routing table to each service board as a transmission routing table.
The unicast routing table of the frame may be a routing table of the service board for performing data transmission in a service frame to which the service board belongs, and may be generated according to an initial route 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 the frame. The multicast routing table may be a routing table used by the service board for performing cross-service frame data interaction, and may be generated by performing and processing on the unicast routing table of each service frame.
In the embodiment of the present invention, when the target upgrade type is a blocked three-level optical transport network cluster, the local frame unicast routing table corresponding to each service frame in the optical transport network cluster may be acquired, the local frame unicast routing table may be stored in each service board of the service frame, the local frame unicast routing table of one service board may be randomly acquired for each service frame, and the acquired local frame unicast routing tables may be subjected to and operation, and all the same routing information in each local frame unicast routing table may be acquired and stored as a multicast routing table, for example, the local frame unicast routing table a stores three pieces of routing information a1, a2 and a3, the local frame unicast routing table B stores two pieces of routing information a1 and B1, the local frame unicast routing table C stores two pieces of routing information a1 and C2, and the same routing information in the local frame unicast routing tables A, B and C is a1, and the local frame unicast routing table a1 may be stored as a multicast routing table. After the multicast routing table is obtained, the multicast routing table can be configured as a transmission routing table in a service board of each service frame in the optical transport network cluster, when the service board sends data of a cross service frame, the service board can rely on the multicast routing table to transfer data, it can be understood that the service board can still rely on the unicast routing table of the frame when sending the data of the service frame, and in the three-level optical transport cluster with resistance, the transmission routing table configured in the service board can comprise the multicast routing table and the unicast routing table of the frame.
According to the technical scheme, the target upgrading attribute and the target upgrading type of the optical transport network cluster are obtained, the cluster intersection attribute of the optical transport network cluster is updated according to the target upgrading attribute, the newly-added service frame and the newly-added center frame are connected into the optical transport network cluster, the cross boards without added optical modules are used as the target cross boards one by one, the offline target cross boards are used, the optical modules are added in the target cross boards, synchronous control is carried out on the data packets according to the transmission links, so that the time stamps of the data packets processed by the service boards of the optical transport network cluster are consistent, the transmission routing table is configured for the service boards according to the target upgrading type, smooth upgrading of the optical transport network cluster is achieved, the influence of an 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 the user requirements, and the upgrading cost of the optical transport network cluster is reduced on the premise of increasing the flow bandwidth.
Furthermore, on the basis of the embodiment of the invention, the position of the cross board to be notified in the service frame is the same as the position of the target cross board in the service frame.
In the embodiment of the invention, when a target cross board is offline in an optical transport network cluster, the optical transport network cluster which is not updated is not completed, the target cross board can only be connected with the cross board in the service frame, the cross board which is in cross-service frame communication needs to pass through the cross board of the center frame, when the target cross board is offline, the cross board which is in cross-service frame and is to be notified can not actively sense that the target cross board is offline, offline information needs to be acquired by the cross board which is to be notified and the offline of the target cross board is realized, the cross board which is to be notified can have the same position as the target cross board, that is, the position of the cross board which is 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 the cross board in the X slot position of the I-th service frame in the optical transport network cluster, and the cross board which is to be notified can be the cross board in the X slot position of other I-1 service frames in the optical transport network cluster.
