Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and more particularly to a method for implementing a zero-touch activator based on FDA services. Background Art

[0002] FDA service (Fiber Dedicated Access) is an access service provided by an ISP to an operator, which allows the operator and its subscribers (end customers) to connect while the ISP remains transparent to the subscribers. It is a shared business model between the ISP and the operator. The ISP provides the last-mile access and bears the traffic, connecting up to the operator's POH. The operator can quickly provide services to customers and save the cost of deploying fiber optics.

[0003] FDA service is designed for enterprise customers, using L2 / L3 infrastructure to provide services, offering services such as MPLS L2 / L3 VPN, DIA, or VoIP to subscribed customers, and adding restrictions according to the bandwidth subscribed by the customers. The three main components provided by the ISP for this service are: access network (last mile), transport / backhaul network, and POH.

[0004] FDA service provides enterprise customers with an MPLS dedicated access service that combines high performance, high reliability, and high security, ensuring the stability and security of data transmission. It does not require customer network topology information and helps protect customer privacy. It seamlessly connects multiple sites of customers, constructs a hub-and-spoke architecture for branch-headquarters, branch-branch, and branch-multi-branch companies, demonstrating high business flexibility and adaptability to the market.

[0005] Currently, the FDA solutions commonly provided in the industry are: one is that the telecom vendor's NMS network management system manually performs resource configuration and activation; the other is to introduce a telecom general service activation management system, which is applicable to the single and fixed GPON service of traditional home broadband. However, the above solutions have problems such as bloated telecom industry products, high costs, lack of an FDA service adaptive intelligent control mechanism, and overly long time-to-market. Summary of the Invention

[0006] The technical task of the present invention is to provide a method for implementing a zero-touch activator based on FDA services to solve the problems of bloated telecom industry products, high costs, lack of an FDA service adaptive intelligent control mechanism, and overly long time-to-market.

[0007] The technical task of the present invention is achieved in the following manner. A method for implementing a zero-touch activator based on FDA services is as follows:

[0008] According to the connection requirements of the end - customer site, resource quotas are automatically allocated in advance to achieve zero - waiting FDA instance resource configuration; among them, the FDA instance resource configuration includes device ONT / NID configuration, primary / standby PE configuration, VPN configuration, and PE - CE configuration.

[0009] Based on the adaptive cruise control mechanism, zero - touch activation of FDA service device configuration is achieved.

[0010] Preferably, the ONT / NID devices owned by the ISP are installed at the customer's site as the demarcation point and configured as L2 / L3 devices; the operator or end - customer is responsible for installing the CE device and connecting the CE device to the ISP's ONT / NID device; the end - customer only subscribes to one bandwidth, and all VLANs (MGMT, data, and voice) must be provided by one bandwidth, and different QoS processing is performed for different VLANs.

[0011] More preferably, according to the connection requirements of the end - customer site, the specific method for automatically allocating resource quotas in advance to achieve zero - waiting FDA instance resource configuration is as follows:

[0012] The activator provides visual FDA resource models, attribute associations, and agile orchestration functions for resource quota policies, completing resource quota allocation with one key, reducing human - interaction errors, improving instantiation configuration efficiency, and enhancing the customer service experience.

[0013] The activator provides an Admin management page. Through the self - service FDA instance resource quota orchestration function, according to the connection types (semi - circuit or full - circuit) and access technologies of different sites, the resource attributes, required fields, filling methods, and resource quota policies of OLT / ONT / NID and primary / standby PE devices can be quickly defined and quota policy controlled.

[0014] The out - of - the - box FDA instance resource configuration template built into the activator supports automatic resource quota allocation. Customers do not need specific professional backgrounds and skills. They only need to simply check the integrity of the values filled in for resource attributes. The activator automatically verifies the accuracy of resource quotas, self - adjusts and corrects missing or incorrect resource configuration data, and customers can use it in seconds without any waiting or staying.

[0015] More preferably, based on the adaptive cruise control mechanism, the specific method for achieving zero - touch activation of FDA service device configuration is as follows:

[0016] The activator is directly connected to OLT / ONT / NID / PE devices through a pre-integrated interface. All devices need to provide available interface protocols and access permissions, and ensure that the network connection is reachable and stable. The activator supports activation process design, instruction execution, and fault tolerance functions to achieve zero-touch automatic activation. At the same time, in view of the enterprise dedicated line service provided by the ISP, the activator realizes activation request operations for different service types.

[0017] The activator API integration adopts multiple interface protocols such as REST / Telnet / SSH, supports connecting to multi-vendor and multi-model devices, and automatically executes FDA service configuration instructions on the devices, with no activation interaction with the device manufacturer's NMS network management.

[0018] More preferably, for the access requirements of multiple sites of the same end customer, the details are as follows:

[0019] The FDA service configuration supports specific grouping and sorting according to the operation type and the designed configuration process.

[0020] The task trigger issues the combined order of interrelated commands to different device groups in sequence.

[0021] Parse the execution result of the activation command, feedback success or failure according to the exception information code, and trigger the fault tolerance processing mechanism (such as network reconnection or command rollback operation, etc.) when an error occurs during activation.

[0022] More preferably, when the network edge (CE) device of the user site is connected to the ISP network, according to key factors such as the site connection type, the number of site accesses, the site coverage, and the subscribed broadband, following the adaptive cruise control mechanism and closely collaborating with the FDA instance resource quota control, it can automatically adjust the combined sequence of device configurations during the FDA service activation process, while monitoring the dynamics of the internal or external device configuration combined sequence, and self-run the optimal service configuration activation process to ensure the safety and reliability of zero-touch FDA service activation.

[0023] More preferably, the adaptive cruise control mechanism performs activation according to the set device combined sequence, and dynamically determines to join or leave the combined sequence based on the resource quotas of internal and external devices (for example: if the resource utilization rate reaches the defined quota threshold, add other interfaces to the LAG), maintaining green and healthy activation management; and for the network connection scenarios of a single site (half circuit) or two sites (full circuit) of the same end customer, configure and activate according to the set device group order; for the interconnection scenarios between multiple sites of different end customers, adapt the FDA instance resource quota to achieve automatic cruise control activation of multiple device groups.

[0024] More preferably, the specific process of installing and activating the FDA service based on NID's MPLS and / or active Ethernet is as follows:

[0025] (1) Based on the connection bandwidth configuration, the required number of single or multi-interfaces (LAG) are provided on the NID;

[0026] (2) The NID ports connected to the CE and PE are configured as Trunk;

[0027] (3) The NID applies S-VLAN to all VLANs received from the CE device and forwards the traffic to the PE as QinQ;

[0028] (4) The PE receives the QinQ traffic, converts the external S-VLAN to O-VLAN, and pushes the traffic to the other side PE;

[0029] (5) According to the bearing services, create VPN instances and configure VRRP protection.

[0030] The implementation method of the FDA service zero-touch activator of the present invention has the following advantages:

[0031] (1) The activator of the present invention provides a zero-waiting, zero-touch, and low-cost device configuration agile management method for FDA services, serving small and medium-sized ISP enterprises, without any middleware platforms such as network element management or resource management systems, supporting flexible direct connection to network elements to achieve activation of multi-vendor and multi-model devices. The product has been verified and is professional and reliable, effectively reducing capital expenditure and operating costs;

[0032] (2) According to the characteristics of ISP's rapid and agile delivery, the present invention designs and optimizes the FDA instance resource configuration and device activation process, provides a comprehensive adaptive configuration activation system for enterprise customers, and realizes automated access management of enterprise end-users at multiple sites; sequentially configures and activates devices such as OLT / ONT / NID / PE for a single or two sites of the same customer, realizes adaptive cruise control activation for the interconnection services between multiple sites of different customers, and adds a fault tolerance mechanism based on transaction management to clearly record the instruction activation results in real time, improving the efficiency and agility of configuration activation, and significantly reducing enterprise IT capital expenditure and operating costs;

[0033] (3) Through the design and optimization of the FDA instance resource quota orchestration and device activation process, the present invention overall meets the high-efficiency, timeliness, and diversity requirements of FDA enterprise dedicated line services; if considering a more cost-effective integrated and automated solution, this solution has the advantages of lower capital expenditure and lower operating costs. The FDA service adaptive cruise control mechanism provides zero-waiting resource orchestration and zero-touch device configuration, realizes rapid deployment of FDA full connection and full services, and shortens the time to market;

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] Attached Figure 1 is a schematic diagram of a point-to-point semi-circuit FDA service;

[0039] Attached Figure 2 is a screenshot of the interface for automatic resource allocation of an FDA instance;

[0040] Attached Figure 3 is an architecture diagram of the adaptive cruise control mechanism for the FDA service. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0041] The method for implementing the zero-touch activator based on the FDA service of the present invention will be described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0042] Embodiment:

[0043] As shown in the attached Figure 3 figure, this embodiment provides a method for implementing a zero-touch activator based on the FDA service, and the method is as follows:

[0044] S1. According to the connection requirements of the end-customer site, automatically allocate resource quotas in advance to achieve zero-waiting FDA instance resource configuration; wherein, the FDA instance resource configuration includes device OLT / ONT / NID configuration, primary / backup PE configuration, VPN configuration, and PE-CE configuration;

[0045] S2. Based on the adaptive cruise control mechanism, achieve zero-touch activation of the FDA service device configuration.

[0046] In this embodiment, the ONT / NID devices owned by the ISP are installed at the customer site as the demarcation point and configured as L2 / L3 devices; the operator or end-customer is responsible for installing the CE device and connecting the CE device to the ISP's device ONT / NID; the end-customer only subscribes to one bandwidth, and all VLANs (MGMT, data, and voice) must be provided by one bandwidth, and different QoS processing is performed on different VLANs.

[0047] This embodiment does not limit the connection type or geographical area. Using the GPON infrastructure, the OLT may be equipped with a point-to-point active Ethernet card, whose function is similar to that of an Ethernet switch. If the bandwidth subscribed by the user is higher than 100M but lower than 1G, or for other service reasons, the user can use the installed P2P active Ethernet card for connection. However, in this case, the NID is installed at the user's location instead of the ONT.

[0048] "Half-circuit" refers to the connection from the end-customer device to the operator's POH. When both ends of the customer link need to be connected through the ISP network, it is called a "full-circuit". In this scenario, two sites of a customer communicate directly through the ISP network without transmitting traffic through the POH or the operator's network. Two different access technologies can be used at both ends of the full-circuit link. For example, one end of the link can use GPON connection and the other end can use MPLS / active Ethernet. As shown in the appendix Figure 1 Point-to-point half-circuit FDA service.

[0049] In step S1 of this embodiment, according to the connection requirements of the end-customer site, automatically allocate resource quotas in advance to achieve zero-waiting FDA instance resource configuration as follows:

[0050] S101. Provide an agile orchestration function for the visual FDA resource model, attribute association, and resource quota policy through the activator, complete resource quota allocation with one key, reduce human interaction errors, improve instantiation configuration efficiency, and enhance the customer service experience;

[0051] S102. Provide an Admin management page through the activator. Through the self-service FDA instance resource quota orchestration function, flexibly define and control the resource attributes, mandatory fields, filling methods, and resource quota policies of OLT / ONT / NID and primary / backup PE devices according to the connection type (half-circuit or full-circuit) and access technology of different sites;

[0052] The FDA instance resource definition and quota policy are as shown in the following table:

[0053]

[0054]

[0055] The out-of-the-box FDA instance resource configuration template built into the activator supports automatic completion of resource quota allocation. Customers do not need specific professional backgrounds and skills. They only need to simply check the integrity of the resource attribute filling values. The activator automatically verifies the accuracy of the resource quota, self-adjusts and corrects the missing or incorrect resource configuration data. Customers do not need to wait or stay at all and can use it within seconds, as shown in the appendix Figure 2As shown

[0056] In this embodiment, the zero-touch activation of the FDA service device configuration based on the adaptive cruise control mechanism in step S2 is specifically as follows:

[0057] S201. The activator is directly connected to the OLT / ONT / NID / PE device through a pre-integrated interface. All devices need to provide available interface protocols and access permissions, and ensure that the network connection is reachable and stable. The activator supports activation process design, instruction execution, and fault tolerance functions to achieve zero-touch automatic activation. At the same time, considering the enterprise dedicated line service provided by the ISP, the activator implements activation request operations for different service types;

[0058] Among them, the types of FDA service activation operations are shown in the following table:

[0059]

[0060] S202. The activator API integration adopts multiple interface protocols such as REST / Telnet / SSH, supports connecting to multi-vendor and multi-model devices, and automatically executes FDA service configuration instructions on the devices, without any activation interaction with the device manufacturer's NMS network management.

[0061] In this embodiment, for the access requirements of multiple sites of the same end customer, it is specifically as follows:

[0064] ③ Analyze the execution results of the activation commands, feedback as successful or failed according to the exception information code, and trigger a fault tolerance processing mechanism (such as network reconnection or command rollback operations) when an error occurs during activation.

[0065] In this embodiment, when the user site network edge (CE) device is connected to the ISP network, according to key factors such as site connection type, site access quantity, site coverage, and subscribed broadband, following the adaptive cruise control mechanism and closely collaborating with the FDA instance resource quota control, it can automatically adjust the combined sequence of device configurations during the FDA service activation process, monitor the dynamic of the internal or external device configuration combined sequence, and self-run the optimal service configuration activation process to ensure the safety and reliability of zero-touch FDA service activation.

[0066] In this embodiment, the adaptive cruise control mechanism is activated according to the set device combination sequence, and dynamically determines to join or leave the combination sequence based on the resource quotas of internal and external devices (for example: if the resource utilization rate reaches the threshold of the defined quota, other interfaces are added to the LAG), maintaining green and healthy activation management; and for the network connection scenarios of a single site (half circuit) or two sites (full circuit) of the same terminal customer, activation is configured according to the set device group order; for the interconnection scenarios between multiple sites of different terminal customers, the resource quotas of the adaptive FDA instances are adjusted to achieve automatic cruise control activation of multiple device groups.

[0067] In this embodiment, the installation and activation process of the MPLS and / or active Ethernet FDA service based on NID is as follows:

[0068] (1) Provide the required number of single or multiple interfaces (LAG) on the NID according to the connection bandwidth configuration;

[0069] (2) Configure the NID ports connected to the CE and PE as Trunk;

[0072] (5) Create a VPN instance according to the bearer service and configure VRRP protection;

[0073] Or, create a Redundancy instance according to the service SLA level and configure VRRP protection.

[0074] Remarks:

[0075] ① The full circuit is equivalent to the connection of two independent half circuits, and the device groups at both ends of the link can be activated according to different connection technologies;

[0076] ② Provide AA / AS redundancy service options, such as Last Mile / Gold SLA: 1 NID, 2 fiber optic routes, 1 POP, Dual Homing / Diamond SLA: 2 NIDs, 2 fiber optic lines, 2 POPs, applicable to all scenarios except the ONT scenario.
