[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0038] The following describes in detail the service processing method provided by the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0039] See Figure 1 , Figure 1 This is a flow chart of a service processing method provided by an embodiment of the present application, which is executed by a bearer device, such as an OTN device. Figure 1 As shown, the method includes the following steps:

[0040] Step 11: Receive service request information from the OLT device.

[0041] The service request information may optionally be service connection establishment request information. In addition to the service signal, the service request information may also include interaction information between an optical line terminal (OLT) and a bearer device, such as an OTN device. A physical connection, such as a 10GE or 100GE connection, may exist between the OLT and the OTN device for information exchange.

[0042] For example, the interaction information between OLT and OTN devices may include but is not limited to:

[0043] 1) Source IP (SIP) address: Optical Network Terminal (ONT) wide area network (WAN) port address;

[0044] 2) Destination IP (DIP) address: business service platform address, such as VR cloud platform address;

[0045] 3) Local IP address: OLT egress IP address; Next hop IP address: Cloud gateway address;

[0046] 4) Service Level Agreement (SLA): bandwidth, latency, priority, robustness, etc.

[0047] 5) Operation type: such as create, modify, delete, etc.

[0048] Step 12: According to the service connection establishment request information, determine the gateway device connected to the service service platform corresponding to the OLT device.

[0049] Optionally, the business service platform in the embodiment of the present application may be a cloud platform, and correspondingly, the gateway device connected thereto is a cloud gateway device.

[0050] Step 13: Based on the preset signaling channel, a service channel is established between the OLT device and the gateway device in the OTN.

[0051] In this embodiment, a preset signaling channel always exists. One end of the preset signaling channel is the OTN source node connected to the OLT device, and the other end is the OTN sink node connected to the gateway device. That is, the starting node is the OTN source node and sink node, and it is used to maintain the connection between the OLT device and the corresponding gateway device. The preset signaling channel is used to implement the IP routing protocol between the OLT device and the corresponding gateway device through the OTN, thereby establishing the OLT device and the corresponding gateway device as the next hop of each other. The preset signaling channel and the established service channel have the same source and sink nodes, that is, the preset signaling channel and the established service channel have the same OTN source node and OTN sink node.

[0052] Optionally, when establishing a service channel, a preset signaling channel can be used to implement signaling transmission required for establishing the service channel, such as bandwidth negotiation, between the OTN source node, the intermediate forwarding node, and the OTN sink node, thereby establishing the service channel. The intermediate forwarding node is a node between the OTN source node and the OTN sink node.

[0053] It should be noted that in the embodiment of the present application, multiple signaling channels can be preset in the OTN, and the starting nodes are different OTN source nodes and / or OTN sink nodes. The OTN source node is connected to the OLT device, and the OTN sink node is connected to the gateway device (such as a cloud gateway device). Figure 2 When the service is launched, the corresponding preset signaling channel is used, such as Figure 2 The signaling channel shown by the thick solid line can establish a service channel with the same source and destination. Figure 2 The OTN schematically only has 6 signaling channels, but the embodiments of the present application are not limited thereto. Dozens, hundreds, or even thousands of signaling channels can be preset based on actual needs.

[0054] The service processing method of the embodiment of the present application, after receiving service connection establishment request information from the OLT device, can determine the gateway device connected to the service service platform corresponding to the OLT device based on the service connection establishment request information, and establish a service channel between the OLT device and the gateway device in the OTN based on the preset signaling channel, with the signaling channel and the service channel having the same source and destination. As a result, the connection between the OLT device and the gateway device can be maintained through the preset signaling channel, and the service channel can be automatically added when the actual service goes online, thereby improving the timely response capability and configuration efficiency of service connection establishment, thereby improving the efficiency of service channel establishment, and meeting the efficient carrying requirements of specific application scenarios or specific services.

[0055] Furthermore, the service connection establishment request information may involve connection establishment requests for multiple services, thereby enabling rapid and accurate configuration when a large number of services are accessed simultaneously, thereby improving the efficiency of establishing service channels.

[0056] Optionally, the services involved in the embodiments of the present application include but are not limited to cloud virtual reality (VR) services. The characteristics of cloud VR services are strong randomness of service access, large user access bandwidth, concentrated number of user access, strong rigid bandwidth guarantee, etc. When terminal users initiate service connection establishment requests in a concentrated manner, such as watching a hot video, the number of service connections established can reach more than tens of thousands. Therefore, by establishing a service channel with the help of the solution in this application, the timely response capability and configuration efficiency of service connection establishment can be greatly improved, thereby improving the efficiency of service channel establishment and meeting the efficient carrying requirements of cloud VR services.

[0057] In the embodiments of the present application, OTN can use time-division multiplexing technology to carry and transmit data at the metro core, metro aggregation, and metro access levels. OTN can use Optical Service Unit (OSU) technology to enable OTN equipment to support OSU functions, thereby meeting requirements such as diversified service rates. In this case, the preset signaling channel in this embodiment is the OSU signaling channel, which is always present and can have a relatively small bandwidth, such as 2 Mbit / s.

[0058] Optionally, the service request information may include, in addition to the service connection establishment request information, service connection deletion request information, service bandwidth adjustment request information, and request information on whether or not to protect a link.

[0059] As an optional embodiment, when the above service request information includes service connection deletion request information, the bearer device can determine the service channel to be deleted based on the service connection deletion request information and delete the service channel to be deleted, thereby ensuring the throughput capacity of the OTN.

[0060] As an optional embodiment, when the above-mentioned service request information includes service bandwidth adjustment request information, the bearer device can determine the target bandwidth and the service channel to be adjusted based on the service bandwidth adjustment request information, and use the target bandwidth to adjust the service channel to be adjusted, thereby meeting diverse service needs.

[0061] The present application is described below with reference to the accompanying drawings and specific embodiments.

[0062] like Figure 3 As shown, the service access process in the embodiment of the present application may include the following steps:

[0063] Step 31: The ONT device is responsible for service perception, accessing the terminal's service signal, and initiating a service request to the OLT device.

[0064] Step 32: The OLT device receives service requests from the ONT device and aggregates multiple service requests, including but not limited to service connection establishment requests, service connection deletion requests, service bandwidth adjustment requests, and requests for link protection, and sends the service requests to the OTN device through the existing physical connection.

[0065] Step 33: The OTN device establishes a service channel, deletes a service channel, and / or adjusts the service channel bandwidth according to the received service request.

[0066] Step 34: The OTN device feeds back the bandwidth provision result.

[0067] Step 35: The OLT device returns the request result to the ONT device.

[0068] like Figure 4 As shown, the service connection establishment process in the embodiment of the present application may include the following steps:

[0069] Step 41: The terminal initiates a service connection establishment request.

[0070] Step 42: The ONT device receives the request initiated by the terminal and initiates a service connection establishment request to the OLT device, including information such as the destination and bandwidth.

[0071] Step 43: The OLT device receives and aggregates the service connection establishment request information from the terminal, and transmits the service connection establishment request information to the OTN device connected thereto.

[0072] Step 44: The OTN device uses the pre-defined signaling channel to establish a service channel between the OLT and the cloud gateway device within the OTN and adjusts bandwidth to deliver services to the cloud platform. The cloud gateway device is connected to the cloud platform that serves the services. The pre-defined signaling channel and the established service channel share the same source and destination. The pre-defined signaling channel can be used to transmit the signaling required to establish the service channel based on the route mapping. The details of the pre-defined signaling channel are described above and will not be elaborated here.

[0073] As you can imagine, after a service goes online, OTN equipment can detect the increase in service traffic in real time through service access cards. These cards receive service requests and trigger the OTN equipment to establish a service connection with sufficient bandwidth for the service. For example, a VR service typically has a bandwidth of approximately 130 Mbit / s. As services increase or decrease, the OLT and OTN equipment interact to request the establishment or deletion of service channels, automatically triggering the OTN equipment to create or delete service channels to deliver the service. OTN equipment can dynamically adjust the number of service channels based on the number of services going online.
