Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method, apparatus, electronic device, and storage medium for switching time slot tables in a network. Background Technology

[0002] With the advancement of 5G network commercialization, Flexible Ethernet (FlexE), a key technology supporting 5G networks, is also being gradually improved. FlexE is used to dynamically adjust service bandwidth, which is achieved through two time slot tables, Calendar A and Calendar B.

[0003] However, in current network environments with multiple network elements, it is necessary to divide each network element into multiple segments and switch the Calendar A and Calendar B time slot tables within each segment. This method is inefficient, requires network elements to be switched segment by segment from two points, and if a switching error occurs at one point, the entire network service will malfunction. Furthermore, controlling the switching of multiple network elements separately increases the operational difficulty for maintenance personnel. Summary of the Invention

[0004] The main objective of this application is to propose a method, apparatus, electronic device, and storage medium for switching time slot tables in a network, aiming to quickly switch time slot tables in multi-network element networking scenarios, enhance the accuracy of time slot table switching, reduce the operational and maintenance difficulty of flexible Ethernet, and improve user experience.

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0020] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no inherent meaning. Therefore, "module," "part," or "unit" may be used interchangeably.

[0021] In order to achieve dynamic bandwidth adjustment without affecting services, the FlexE network introduces two time slot tables, Calendar A and Calendar B. When bandwidth needs to be adjusted, the current time slot table (main table) used by the service flow can be maintained, and the information in the other time slot table can be modified. By switching between the two time slot tables, the purpose of dynamically adjusting bandwidth under different service impact conditions can be achieved. Figure 1 This is an example diagram of the FlexE OH frame format in existing technology. FlexE OH frames carrying two time slot tables for services can be configured as follows: Figure 1 As shown, two nodes in the network receive and send data via FlexE OH frames. The upstream node sends the time slot table for service transmission to the downstream node in the FlexE OH frame. After receiving the data, the downstream node automatically extracts the time slot table from the FlexE OH frame and automatically configures the receiving side. However, when multiple network nodes switch time slot tables together, two adjacent nodes need to interact with each other via FlexE OH frames to achieve time slot table switching, resulting in extremely low switching efficiency and requiring maintenance personnel to be familiar with the operation of each network node to switch time slot tables. To achieve fast switching of time slot tables in flexible Ethernet networks with multiple network elements cross-networking, this application proposes a network time slot table switching method to improve switching efficiency and reduce the maintenance difficulty for maintenance personnel.

[0022] Figure 2 This is a flowchart illustrating a network time slot table switching method provided in an embodiment of this application. This embodiment is applicable to time slot table switching in Flexible Ethernet, where Flexible Ethernet can include service end nodes and intermediate service nodes. A typical three-point crossover Flexible Ethernet network can be as follows: Figure 3 As shown. This method can be executed by a network time slot table switching device, which can be implemented by software and / or hardware. The method in this embodiment specifically includes the following steps:

[0023] Step 110: Determine the communication line between the starting network element and the ending network element.

[0024] In this context, the originating and ending network elements can be network element nodes in a flexible Ethernet network that require time slot table switching. These elements can be determined by the service; for example, they could be service-end nodes of a service flow for which the operator requires bandwidth changes. Specifically, the originating and ending network elements can be the terminating service nodes of a cross-connected flexible Ethernet network. The communication line can be a communication link connecting the originating and ending network elements, and can include both software and hardware connections. The communication line can consist of one or more intermediate service nodes. It is understood that the originating and ending network elements can interact with each other through one or more intermediate service nodes in the communication line.

[0025] Specifically, when dynamically adjusting service bandwidth, the service endpoints corresponding to the service flows with adjusted bandwidth can be designated as the starting and ending network elements, respectively. Intermediate service nodes connecting these starting and ending network elements can be located within the flexible Ethernet network. These intermediate service nodes can be network elements in a cross-connected Ethernet network, and these network elements can be terminal devices that implement time slot cross-connection. The found intermediate service nodes can be arranged according to the connection order of hardware links or software connections to form communication lines.

[0026] Step 120: Sequentially switch the time slot table of the intermediate service node on the communication line and the time slot table of the endpoint network element.

[0027] Among them, the intermediate service node can be a service node configured with time slot cross-connection in flexible Ethernet, which can forward service flows to the starting network element and the ending network element, or specifically a cross-connection service node in cross-networking.

[0028] In this embodiment of the invention, the time slot table currently in use at the intermediate service nodes can be switched to another spare time slot table sequentially according to the arrangement order of the communication lines. After the intermediate service nodes switch their time slot tables, the time slot table currently in use at the destination network element can be switched to the spare time slot table. For example, the communication line from the starting network element PE1 to the destination network element PE2 is composed of intermediate service nodes P1, P2, P3, and P4 in sequence. When switching the time slot table, the time slot tables of P1, P2, P3, P4, and PE2 can be switched sequentially according to the arrangement order of the intermediate service nodes of the communication line.

[0029] In this embodiment, by determining the communication lines corresponding to the starting and ending network elements, the operation difficulty of switching the time slot tables of intermediate service nodes and the ending network element is reduced and the speed of time slot table switching is improved by controlling the switching of the time slot tables of the intermediate service nodes and the ending network element according to the communication lines, thereby enhancing the user experience.

[0030] Furthermore, based on the above-mentioned application embodiments, it also includes: determining that the communication line between the starting network element and the ending network element is communicating normally.

[0031] In this embodiment of the application, before switching the time slot table through the communication line, the communication line can be detected to determine whether the starting network element and the ending network element can communicate normally through the communication line. The starting network element can send a detection message to the ending network element through the communication line. When the starting network element receives the feedback message generated by the ending network element based on the detection message, it is determined that the starting network element and the ending network element can communicate normally through the communication line.

[0032] Figure 4This is a flowchart of another network time slot table switching method provided in this application embodiment. This application embodiment is a specific embodiment based on the above embodiment. See also... Figure 4 The method proposed in this application specifically includes the following steps:

[0033] Step 210: Determine the starting and ending network elements in the service-side nodes of the Flexible Ethernet.

[0034] In this embodiment, a service flow undergoing bandwidth adjustment can be obtained. The service-end nodes of the service flow can be used as the starting network element and the ending network element, respectively. One node can be selected from the service-end nodes of the service flow as the starting network element for initiating the time slot table switch. Correspondingly, other nodes of the service-end nodes of the service flow can be used as the ending network elements. The ending network element can be identified by custom recognition through the OAM protocol.

[0035] Step 220: Determine the communication line between the physical port of the starting network element and the physical port of the ending network element.

[0036] Specifically, the starting network element and the ending network element are connected through fixed physical ports in the flexible Ethernet underlay Sh IM. The starting network element and the ending network element can have a unique communication link. The corresponding communication link can be found by looking up the physical port of the starting network element and the physical port of the ending network element, which is the communication line corresponding to the starting network element and the ending network element.

[0037] Step 230: Control the starting network element to send a status confirmation request message to the ending network element along the communication line.

[0038] In this embodiment of the application, the starting network element can be controlled to send a status confirmation request message to the ending network element. The status confirmation request message can be sent down to the ending network element through intermediate service nodes in the communication line. It can be understood that the starting network element can send the status confirmation request message to the ending network element through the Operation Administration and Maintenance (OAM) protocol message.

[0039] Step 240: If the endpoint network element receives a time slot table switching request message, control the endpoint network element to send a status confirmation message back to the starting network element through the communication line.

[0040] Specifically, the endpoint network element can receive status confirmation request messages transmitted in the communication line. After receiving the status confirmation request message, the endpoint network element can send a status confirmation message back to the originating network element. Correspondingly, the endpoint network element can also send the status confirmation message back to the originating network element through the OAM protocol.

[0041] Step 250: If the starting network element receives the status confirmation message within the preset time, the communication line will communicate normally; otherwise, a status confirmation timeout alarm will be triggered.

[0042] The preset time can be the maximum waiting time for the destination network element. If the starting network element does not receive a status confirmation message from the destination network element within the preset time range, it can be determined that the starting network element and the destination network element cannot communicate normally.

[0043] In an exemplary implementation, after sending a status confirmation request message, the starting network element can start a timer to record a preset time. If a status confirmation message is received from the ending network element within the preset time range, it is determined that the communication between the starting network element and the ending network element is normal and can be switched. If no status confirmation message is received from the ending network element within the preset time, it is determined that the starting network element and the ending network element cannot communicate normally, and an alarm notification of status confirmation timeout can be sent to the network management system.

[0044] Step 260: Control the starting network element to transmit the time slot table switching request to the ending network element through the communication line.

[0045] Specifically, after confirming that the communication between the starting network element and the ending network element is normal, the starting network element can send a time slot table switching request to the ending network element through the communication line. The time slot table switching request can be transmitted one by one through the intermediate service nodes in the communication line until the time slot table switching request is sent to the ending network element. It can be understood that during the transmission of the time slot table switching request, the intermediate service nodes only need to send the time slot table switching request to the next intermediate service node, without modifying the time slot table switching request.

[0046] Step 270: During the transmission of the time slot table switching request, when the endpoint network element or intermediate service node receives the time slot table switching request, the current time slot table of the endpoint network element or intermediate service node is switched to the backup time slot table.

[0047] The current timeslot table can be the timeslot table currently in use by each network device in Flexible Ethernet, and the spare timeslot table can be the timeslot table used by each network device in Flexible Ethernet for switching. The information in the timeslot table can correspond to the bandwidth after the switch.

[0048] In this embodiment, during the process of transmitting the time slot table switching request to the destination network element via a switching communication route, each time the time slot table switching request reaches an intermediate service node, the intermediate service node can switch its local current time slot table to a backup time slot table. It can be understood that the backup time slot table can be modified to correspond to the adjusted service bandwidth. As the time slot table switching request is transmitted node by node through the intermediate service nodes to the destination network element, time slot table switching can be performed on each intermediate service node until the time slot table switching request reaches the destination network element. Finally, the destination network element switches its currently used current time slot table to a backup time slot table according to the time slot table switching request.

[0049] Step 280: Control the endpoint network element to send the handover completion information back to the originating network element, and complete the time slot table handover when the originating network element receives the handover completion information.

[0050] The handover completion information can be a notification sent by the endpoint network element to the originating network element to complete the time slot table handover. It can be sent via a message, for example, the handover completion information can be carried in an OAM protocol message.

[0051] Specifically, after the endpoint network element completes the time slot table switch, it can generate switch completion information and feed this switch completion information back to the originating network element. When the originating network element completes the switch, the time slot table of the originating network element to the endpoint network element is switched.

[0052] Furthermore, based on the above-mentioned application embodiments, the step of controlling the endpoint network element to feed back handover completion information to the originating network element, and completing the time slot table handover upon the originating network element receiving the handover completion information, includes:

[0053] After the endpoint network element completes the time slot table switch, it sends a completion message to the starting network element through the communication line. The completion message includes switch completion information. If the starting network element receives the completion message, it notifies the network management system to complete the time slot table switch.

[0054] In this embodiment, after switching the time slot table, the endpoint network element sends a handover completion message to the originating network element via a completion message. This completion message can be an OAM protocol message. Specifically, the completion message can be sent from the endpoint network element to the originating network element along intermediate service nodes of the communication line. The handover completion information can be sent to the originating network element via this completion message. When the originating network element receives the completion message, it can determine that all nodes from the originating network element to the endpoint network element have completed the time slot table switch. At this time, it can send a notification message to the network management system to inform it that the flexible Ethernet time slot table switch is complete.

[0055] In this embodiment, by determining the starting and ending network elements in the service-side nodes of the time slot table to be switched in Flexible Ethernet, and determining the physical ports of the starting and ending network elements to establish a communication line, the starting network element sends a status confirmation request message along the communication line. After receiving the status confirmation request message, the ending network element sends back a status confirmation message. If the starting network element receives the status confirmation message within a preset time, it is determined that the communication is normal; otherwise, a status confirmation timeout alarm is triggered. The starting network element transmits a time slot table switching request to the ending network element through the communication line. When the intermediate cross nodes in the communication line receive the time slot table switching request, they perform the time slot table switching and continue to transmit the time slot table switching request until the ending network element completes the time slot table switching. The ending network element sends a completion message back to the starting network element. After the starting network element receives the completion message, the time slot table switching of Flexible Ethernet is completed. This improves the speed of time slot table switching, reduces the operational difficulty for maintenance personnel in performing time slot table switching, and enhances the user experience.

[0056] Furthermore, based on the above application embodiments, at least one of the status confirmation request message, the status confirmation message, and the completion message is implemented by marking reserved bits in the OAM operation maintenance management basic code block.

[0057] In this embodiment of the application, the OAM operation and maintenance management basic code block can be used to send status confirmation request messages, status confirmation messages, and feedback completion messages. Figure 5 This is a schematic diagram of the structure of a basic code block for OAM operation and maintenance management provided in an embodiment of this application. See also... Figure 5 The reserved bits of the OAM operation, maintenance and management basic code block can be marked. Different marking bits represent different messages. The first marking bit can be used as the marking bit of the status confirmation request message CR, the second marking bit can be used as the marking bit of the status confirmation message CA, and the third marking bit can be used as the marking bit of the completion message Done. Message generation is achieved by marking the corresponding marking bits as 1 or 0.

[0058] In one exemplary implementation, in a flexible Ethernet, terminating service nodes PE1 and PE2 are connected via a cross-connect service node P, and the switching method for timeslot table A and timeslot table B may include the following steps:

[0059] Step 1: Determine the starting and ending network elements for flexible Ethernet timeslot table switching.

[0060] (1) The starting network element can be the initiator of the time slot table A and time slot table B switching. If the time slot table switching is initiated from the PE1 node, then PE1 will be the starting network element of the time slot table switching. The ending network element can be identified through the OAM custom protocol.

[0061] (2) PE1 node sends a CR request message (CR=1|CA=0|Done=0) through the OAM custom protocol, and then passes it through the cross-service node P to the destination network element PE2.

[0062] (3) After receiving the OAM custom protocol message, the PE2 node replies with a CA reply message (CR=0|CA=1|Done=0).

[0063] (4) If the PE1 node does not receive a CA reply message within 3 consecutive OAM cycles, it reports a CA timeout alarm to the network management system.

[0064] (5) After PE1 receives the CA message from PE2 within 3 OAM cycles, it proceeds to step 2.

[0065] Step 2: The starting network element initiates a time slot table switching request to downstream nodes segment by segment.

[0066] (1) PE1 initiates a time slot table switching request to the downstream cross-service node P in accordance with the FlexE standard protocol.

[0067] (2) After the cross-connect service node P completes the time slot table switch, the outgoing physical port of the cross-connect can be found through the software.

[0068] (3) Cross-service node P initiates a time slot switching request to the downstream PE2 node through the outgoing physical port.

[0069] (4) After the PE2 node completes the time slot switching, proceed to step 3.

[0070] Step 3: Notify the PE1 node that the time slot switching is complete via a custom OAM protocol.

[0071] (1) The PE2 node replies with a Done message to notify PE1 that the time slot table switch is complete (CR=0|CA=1|Done=1).

[0072] (2) After receiving the Done message from PE2, PE1 notifies the network management system that the entire handover process is complete.
