In an embodiment, referring to fig. 2, fig. 2 is a flowchart illustrating a service recovery method according to an embodiment of the present invention. As shown in fig. 2, the service recovery method includes:
step S10, starting lossless bandwidth adjustment on a link, and storing original time slot information of each ODUflex node participating in adjustment on the link and target time slot information expected to be adjusted;
in this embodiment, after starting lossless bandwidth adjustment on a link, original timeslot information of each ODUflex node participating in adjustment on the link and target timeslot information that is expected to be adjusted by the lossless bandwidth adjustment this time are acquired, and the original timeslot information of each ODUflex node participating in adjustment on the link and the target timeslot information that is expected to be adjusted are stored.
Step S20, in the lossless bandwidth adjustment process, if the service borne by the link is interrupted, adjust the timeslot of each ODUflex node to the timeslot corresponding to the target timeslot information of each ODUflex node according to the state of each ODUflex node, and the original timeslot information and target timeslot information of each ODUflex node.
In this embodiment, in the lossless bandwidth adjustment process, if a service carried by the link is interrupted, the timeslot of each ODUflex node is adjusted to the timeslot corresponding to the target timeslot information of each ODUflex node according to the stored original timeslot information of each ODUflex node participating in adjustment on the link and the target timeslot information that is expected to be adjusted. Since the states of the ODUflex nodes are not uniform, the timeslot of each ODUflex node needs to be adjusted to the timeslot corresponding to the target timeslot information in a corresponding manner according to the state of each ODUflex node. For example, if the state of an ODUflex node is a state waiting for lossless bandwidth adjustment, waiting is stopped, the current service cross configuration is cleared according to the stored original timeslot information of the ODUflex node, and then service cross is reconstructed according to the stored target timeslot information of the ODUflex node. And if the ODUflex node is in lossless bandwidth adjustment, forcibly quitting the lossless bandwidth adjustment, clearing the current service cross configuration according to the stored original time slot information of the ODUflex node, and then reconstructing service cross according to the stored target time slot information of the ODUflex node. If an ODUflex node has completed lossless bandwidth adjustment, the timeslot of the ODUflex node has been adjusted to the timeslot corresponding to the target timeslot information, and no operation is required.
After lossless bandwidth adjustment of a link is started, the state of each ODUflex node is stored, and when the state of the ODUflex node changes, the state of the ODUflex node is updated.
In this embodiment, lossless bandwidth adjustment on a link is started, and original timeslot information of each ODUflex node participating in adjustment on the link and target timeslot information that is expected to be adjusted are stored; in the lossless bandwidth adjustment process, if the service carried by the link is interrupted, the timeslot of each ODUflex node is adjusted to the timeslot corresponding to the target timeslot information of each ODUflex node according to the state of each ODUflex node, the original timeslot information of each ODUflex node, and the target timeslot information. Through the embodiment, in the lossless bandwidth adjustment process, if a service is interrupted, the timeslot of each ODUflex node is directly adjusted to the timeslot corresponding to the target timeslot information of each ODUflex node, so that the bandwidth of the whole link is adjusted to the bandwidth to which the lossless bandwidth adjustment is expected to be started, and thus, the rapid recovery of the service is realized.

In this embodiment, if the state of the ODUflex node is a waiting state, the waiting is stopped, the existing mapping of the board card corresponding to the ODUflex node is released according to the original timeslot information of the ODUflex node, the released mapping is reconstructed according to the target timeslot information of the ODUflex node, and the cross is recovered; if the state of the ODUflex node is in the adjustment state, firstly quitting lossless bandwidth adjustment, then removing the existing mapping of the board card corresponding to the ODUflex node according to the original time slot information of the ODUflex node, reconstructing the removed mapping according to the target time slot information of the ODUflex node, and recovering the cross; if the state of the ODUflex node is the adjustment end state, the timeslot of the ODUflex node is adjusted to the timeslot corresponding to the target timeslot information, and no operation is required.
Further, in an embodiment, the service recovery method further includes:
detecting whether an ODUflex node with the state being an in-adjustment state or an adjustment ending state exists according to the state of each ODUflex node;
when there is an ODUflex node whose state is the in-tuning state or the tuning end state, step S201 is performed.
In this embodiment, in the lossless bandwidth adjustment process, if a service carried by a link is interrupted, whether an ODUflex node whose state is an in-adjustment state or an adjustment termination state exists is detected according to the state of each ODUflex node at this time, and when an ODUflex node whose state is an in-adjustment state or an adjustment termination state exists, step S201 is performed, so that a timeslot of each ODUflex node is adjusted to a timeslot corresponding to target timeslot information of each ODUflex node, and thus the bandwidth of the entire link is adjusted to a bandwidth to which the lossless bandwidth adjustment is expected to be started, thereby achieving rapid restoration of the service.
Further, in an embodiment, after the step of detecting, according to the state of each ODUflex node, whether there is an ODUflex node whose state is an in-tuning state or an end-tuning state, the method further includes:
and when the ODUflex node with the state being the adjustment state or the adjustment ending state does not exist, stopping waiting if the state of the ODUflex node is the waiting state.

Further, in an embodiment, after the step of initiating the lossless bandwidth adjustment on the link, the method further includes:
determining and storing the board card type corresponding to each ODUflex node according to the service type corresponding to each ODUflex node, wherein when the service type corresponding to the ODUflex node is an Ethernet OTU service, the corresponding board card type is a branch board card, when the service type corresponding to the ODUflex node is the OTU service of the OTU, the corresponding board card type is a line OTU board card, and when the service type corresponding to the ODUflex node is the packet service of the OTU, the corresponding board card type is a line packet board card.
In this embodiment, after the lossless bandwidth adjustment of the link is started, the board card type corresponding to each ODUflex node participating in the adjustment on the link needs to be stored. And determining and storing the board card type corresponding to each ODUflex node according to the service type corresponding to each ODUflex node. For example, if a service type corresponding to an ODUflex node is an ethernet OTU service, the corresponding board card type is a branch board card; if the service type corresponding to one ODUflex node is the OTU service of the OTU, the corresponding board card type is a line OTU board card; and if the service type corresponding to one ODUflex node is the OTU packet service, the corresponding board card type is the circuit packet board card.

In this embodiment, different mappings are established for different board card types. Therefore, the existing mapping needs to be released according to the board card type corresponding to the ODUflex node and the original timeslot information. For example, when the board card type corresponding to the ODUflex node is a tributary board card, the existing client map mapping is released according to the original time slot information of the ODUflex node; when the type of the board card corresponding to the ODUflex node is a line OTU board card, removing the existing oduk mux mapping according to the original time slot information of the ODUflex node; and when the type of the board card corresponding to the ODUflex node is a circuit grouping board card, the existing client map and odukmux mapping are released according to the original time slot information of the ODUflex node.
