Description

Technical Field

[0001] The present invention relates to the technical field of broadband network construction, and is particularly applicable to a method for instantly generating a point-to-point network based on a broadband core network. Background Art

[0002] Point-to-point network can provide point-to-point and point-to-multipoint data, image, and voice transmission services, and can also be used as a data link for private networks such as frame relay networks and the Internet. At the same time, circuits can be opened for customers according to their needs. Point-to-point network dedicated lines have the advantages of rich network resources, standard terminal access equipment interfaces, transparent transmission channels and high transmission rates, the network itself has self-healing functions, and are relatively cheap.

[0003] Currently, telecom operators are unable to provide users with value-added services based on broadband networks to open point-to-point network dedicated lines in real time. This directly leads to the inability to obtain stable and high-speed network support in time when enterprises face urgent business needs, such as temporary large-scale data transmission and sudden remote video conferencing, resulting in business delays, missed business opportunities, and affecting the normal operation and market competitiveness of enterprises. In the face of emergencies such as natural disasters and public health events, when it is necessary to quickly establish reliable communication links to ensure rescue command, medical data transmission and other work, they cannot be carried out in a timely and efficient manner, which has an adverse impact on disaster relief and public safety.

[0004] From the perspective of users and enterprises, enterprises need to adopt other temporary network solutions, such as temporarily renting high-bandwidth Internet lines or using mobile data networks, which will increase enterprise operating costs. From the perspective of telecom operators, the inability to provide real-time point-to-point network dedicated line services may cause telecom operators' resources to be idle, reduce resource utilization efficiency, increase unit costs, and at the same time, make customers question the service quality of operators, reduce customer satisfaction and loyalty, and thus affect the market reputation and business expansion of operators.

[0005] Moreover, in today's era of information explosion, some projects involving multiple links and multi-party cooperation must be based on real-time point-to-point networks. If real-time point-to-point network services cannot be provided, the progress of some projects will be hindered, increasing project costs and risks, resulting in the inability to test and apply projects in a timely manner and losing market opportunities.

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The method for instant generation of a point-to-point network based on a broadband core network described in the present invention is based on a network architecture of a broadband core network.

[0024] The broadband core network BNC is mainly responsible for access control, service management and traffic forwarding of broadband services, and adopts a forwarding and control separation architecture. The broadband core network BNC includes the broadband core network control plane CP and the user plane CP, and is managed by a unified BNC management and control system, which is responsible for the management and operation of the BNC system, service status monitoring, alarm management, rapid fault location and demarcation, service configuration, etc.

[0025] The BNC control plane includes the control plane functions (CTRL, UPMNG, ACC, etc.) of the traditional broadband network gateway (BNG), AAA server, DHCP server, as well as CDN control plane, intelligent business analysis (CAM) and other network elements to realize functions such as user access control and business management. In the future, the control plane network elements should evolve towards a service-oriented architecture. The various control plane network elements should be interconnected using service-oriented interfaces, and the necessary control plane network elements should be selected and deployed according to the needs of network business development.

[0026] The BNC user plane is mainly responsible for user service traffic forwarding and traffic control. According to business development needs, it deploys SAC / SAD network elements on demand to provide business intelligent perception and value-added services, and deploys CDN resource pools to provide CDN services.

[0027] Each BNC network element and management and control system should support IPv4 / IPv6 dual-stack mode and IPv6 single-stack mode.

[0028] The main functions of the BNC control plane BNC-CP include CTRL, UPMNG, ACC, AAA, DHCP, CAM and CDN control plane modules. The main functions of each module are as follows: CTRL: Control module, responsible for allocating IP addresses to users and interacting with various servers.

[0029] UPMNG: Management module, responsible for UP device status management, sending configurations to UP, and creating and distributing forwarding table entries.

[0030] ACC: Access module, responsible for processing PPPoE and DHCP dial-up messages.

[0031] AAA: responsible for authentication, authorization and accounting functions.

[0032] DHCP: Address module, responsible for address management and allocation.

[0033] CAM: A central analysis platform that works with the intelligent traffic collection unit and is responsible for collecting user flow logs and policy coordination.

[0034] CDN control plane: responsible for CDN policy control, etc.

[0035] The main functions of the BNC user plane include BNC-UP, SAU, CDN and other modules. The main functions of each module are as follows: BNC-UP: UP module, responsible for completing functions such as user service traffic forwarding and traffic control, including: traffic forwarding, QoS, traffic statistics, unicast routing protocol, multicast routing protocol, SRv6 and other forwarding plane functions.

[0036] SAU: Service Awareness Unit, responsible for completing service collection, analysis and reporting functions, including: SAC (plug-in service awareness unit) and SAD (stand-alone service awareness unit).

[0037] CDN: Content provision module, responsible for providing content services to users.

[0038] In the broadband core network architecture, the access network construction realizes the construction of fiber to the home FTTH and distributes ONU (optical modem) to home users. The bearer network includes BNC-UP, BNC-CP, BSS, OSS and other related systems.

[0039] After the home user ONU (optical modem) device is powered on, the PON link layer registration authentication is started. First, the OLT in the PON optical network unit broadcasts a discovery GATE message to notify the ONU of the discovery window period. The ONU sends a registration request message containing the MAC address to implement ONU registration, and allocates and formulates LLID for the ONU, binding MAC and LLID.

[0040] If it is a non-PON access network (i.e., a home / enterprise gateway is used), the ONU is substituted for the home / enterprise gateway. After the link connection between the OLT and the ONU is completed, the ONU starts to authenticate the terminal management system, in order to enable the RMS terminal management system to manage and configure various CPEs (including the business services of ONUs of various manufacturers without distinction). The TR069 protocol is currently commonly used.

[0041] After the above two steps, the optical modem ONU has established a network connection to the bearer network, the user plane UP and control plane CP of the broadband core network have established a data link, and have established a connection with the management system of the relevant access network, such as the RMS optical modem management system.

[0042] After that, the user activates the basic broadband Internet access service and realizes basic broadband Internet access through PPPOE dial-up authentication. On the control plane, the home user ONU (optical modem) starts the PPPOE process and broadcasts the PADI message to the broadband core network pool end UP. The broadband core network UP encapsulates the message into the VXLAN tunnel and sends it to the broadband core network CP for judgment. The broadband core network CP selects a suitable broadband core network UP to carry the ONU's service; then unicast replies to the ONU with PADO, and subsequent PADR / PADS messages are all unicast and sent between the designated broadband core network UP and the home user ONU (optical modem).

[0043] The ONU starts the PPP three-stage negotiation process, and the AAA server interacts with the ONU for authentication to complete the ONU authentication. The AAA server notifies the DHCP server to allocate an IP address to the ONU, completing the three-stage negotiation process. After the three-stage negotiation process is completed, the operator's AAA server notifies the broadband core network CP to send the forwarding flow table to the broadband core network UP, and the broadband core network UP converts the received flow table into a local forwarding table entry. The AAA server notifies the CP to start the billing process.

[0044] On the data plane, the ONU receives service traffic within the LAN (home local area network), sets the destination MAC to the broadband core network UP virtual MAC, the source IP to the ONU itself, and sends it to the corresponding broadband core network UP through the access network. After receiving it, the broadband core network UP looks up the routing table of the bearer network and forwards it (NAT conversion address lookup table forwarding) to the CR (core router), and the CR public network forwards it to the bearer network.

[0045] In the method for instant generation of a point-to-point network based on a broadband core network of the present invention, both parties of the instant point-to-point network, namely the initiating user and the target user, need to access the access network and the access network management system through the optical modem ONU, establish data links with the user plane UP and the control plane CP of the broadband core network, and activate basic broadband Internet access services. Then, the initiating user can initiate the instant point-to-point network application, activation and cancellation process through the BNC network service mall system.

[0046] Among them, the BNC network business mall system presets the instant point-to-point network tariffs and establishes connections with the broadband core network control plane CP, BSS system, OSS system and AAA system.

[0047] like Figure 1 As shown, the instant point-to-point network application process includes: S1.1, the initiating user enters the BNC network business mall system through the client.

[0048] S1.2, the BNC network business mall system obtains the broadband line account of the initiating user.

[0049] The method of entering the BNC network business mall system and obtaining the broadband line account of the initiating user is as follows: a) Pre-set the QR code, which is bound to the BNC network business mall system and the user's broadband line account. The initiating user's mobile phone scans the code to enter the BNC network business mall system, and the user's broadband line account is linked to the QR code.

[0050] b) The initiating user logs in to the BNC network business mall system website. The BNC network business mall system website reads the initiating user's optical modem information and queries the OSS system (Operations Support System) to obtain the user's broadband line account.

[0051] The OSS system contains the terminal ID of the RMS system (which manages ONU, home / enterprise gateways and other terminals) and the user's broadband line account, fiber-optic IoT line and port and other related information.

[0052] c) The initiating user logs into the BNC network business mall system and manually enters the user's broadband line account.

[0053] S1.3, the initiating user enters the instant point-to-point dedicated line service module in the BNC network service mall system, fills in the instant point-to-point network service information and target user information, and initiates the instant point-to-point network application.

[0054] The target user information reporting method includes: inputting the target user's broadband line account, standard address or access network terminal ID; inputting the target user's location on the GIS map. Since the BNC network business mall system is connected with the BSS system, OSS system and AAA system, the OSS system contains the terminal ID of the RMS system (managing ONU, home / enterprise gateway and other terminals) and the user's broadband line account, optical fiber IoT line and port and other related information. The BSS system contains the standard address and the user and broadband line user account and other related information, so the target user can be determined through data mutual query.

[0055] The BNC network business mall system can also display the status of the existing services of the initiating user, such as the upstream and downstream rates, service level SLA, etc. Service level SLA includes fixed bandwidth, guaranteed bandwidth or best effort. The definition of fixed bandwidth is that the bandwidth must be reserved for the customer regardless of whether the user uses it or not, and other customers cannot use it; the definition of guaranteed bandwidth is that the bandwidth is given priority to the customer, that is, the customer has the highest priority, and when the customer does not use it, it can also be used by other customers.

[0056] The real-time point-to-point network service information that needs to be reported includes the upstream and downstream speeds of establishing the real-time point-to-point network, service level SLA, purchase duration (year, month, day, etc.) and the broadband line account of the initiating user.

[0057] S1.4, the BNC network service mall system checks whether the broadband line accounts of the initiating user and the target user exist and have been activated; if both exist, the tariff is confirmed to the initiating user based on the instant point-to-point network service information. If any broadband line account of the initiating user and the target user does not exist or has not activated the basic broadband service, the instant point-to-point network cannot be activated.

[0058] S1.5, after the initiating user confirms, the BNC online business mall system submits payment confirmation to the BSS system.

[0059] S1.6, after the settlement is completed, the BSS system and the BNC network service mall system start the instant point-to-point network service and retain the original service information of the initiating user and the target user.

[0060] The opening of the instant point-to-point network includes respectively slicing the bearer network segment, slicing the access network segment and setting the user gateway for the initiating user and the target user, setting the bearer network segment slice interface, access network segment slice interface and user gateway WAN interface of the initiating user and the target user respectively as the only associated channel, controlling the bearer network exports of the initiating user and the target user through the BNC network service mall system to form FlexE time slot docking, and binding the LAG ports corresponding to the bearer network exports of the initiating user and the target user to a warm standby group, so as to open up the instant point-to-point network from the initiating user to the target user.

[0061] like Figure 2 As shown, the bearer network segment slice includes: S2.1.1, according to the information of the instant point-to-point network service, the uplink and downlink rate configuration parameters are respectively sent to the BNC-UP where the initiating user and the target user are located through the BNC-CP where the initiating user and the target user are located.

[0062] S2.1.2, the BNC-UP where the initiating user and the target user are located respectively queries the entire forwarding table entry from the initiating user to the target user's bearer network.

[0063] S2.1.3, the BNC-UP where the initiating user and the target user are located respectively enables the FlexE function for the bearer devices hop by hop from the initiating user to the target user's bearer network egress. Each interface of each bearer device hop by hop is divided into N FlexE interfaces.

[0064] FlexE (Flexible Ethernet) technology is a technology based on high-speed Ethernet interfaces. By decoupling the Ethernet MAC layer from the PHY layer, it can flexibly control the interface rate to adapt to different network transmission structures. FlexE technology can flexibly adjust the channel bandwidth in different network transmission structures, thereby achieving efficient bearing and better compatibility.

[0065] S2.1.4, the BNC-UP where the initiating user and the target user are located respectively selects the FlexE interfaces of different physical ports of the same subcard of the bearer network device to form a LAG port. Warm standby means that the backup resource is in standby state, but not in operation. Only after the main resource fails, the backup resource will be started, synchronized, and then take over the work. LAG (link aggregation) is a technology that combines multiple Ethernet links into a single logical link in parallel. By combining multiple physical links into one logical link, LAG can improve the bandwidth and reliability of the link while providing load balancing function.

[0066] S2.1.5, the BNC-UP where the initiating user and the target user are located determines the LAG port bandwidth according to the downlink rate configuration parameters sent by the corresponding BNC-CP. On the large pipe physical port, several sub-channel ports are divided through FlexE time slot multiplexing, and these sub-channel port slices are divided into different slices of the network slice. Through hardware time slot multiplexing, the services between each slice are completely isolated at the forwarding level. The services between slices do not affect each other.

[0067] The newly added slicing implementation of the BNC-UP device complies with the general protocol standard. The basic slicing capabilities are the same as those of intelligent metropolitan area network devices and can be connected to the bearer network devices of different manufacturers in the existing network.

[0068] like Figure 3 As shown, the access network segment slice includes: S2.2.1, the BNC network service mall system issues a slicing instruction to the OSS system, along with configuration parameters for the uplink and downlink rates of real-time point-to-point network services; S 2.2.2, OSS sends instructions to the PON network management system to define the fiber broadband logical layer slice from the OLT device to the home gateway device (optical modem), and sets relevant parameters according to user-defined requirements, including QOS-related parameters (fixed bandwidth, guaranteed bandwidth, latency, upstream and downstream rates, packet loss rate, jitter, etc.), business-related parameters (security isolation), etc.

[0069] Logical layer slicing refers to dividing logical slices through the dynamic bandwidth allocation (DBA) algorithm, which allows bandwidth allocation to be dynamically adjusted according to service requirements.

[0070] like Figure 4 As shown, the user gateway setting includes: S2.3.1, the BNC network service mall system issues an instant point-to-point network generation instruction to the RMS home gateway management system.

[0071] S2.3.2, the RMS home gateway management system issues point-to-point network configuration settings to the home gateway or ONU, including adding a new WAN port, including upstream and downstream rates and intranet LAN port settings and parameters.

[0072] Afterwards, the bearer network segment slice interface, access network segment slice interface and user gateway WAN interface of the initiating user end are set as associated channels. The bearer network segment slice interface, access network segment slice interface and user gateway WAN interface of the target user end are set as associated channels.

[0073] Then, the BNC network service mall system controls the export IoT interface between the bearer network of the initiating user end and the bearer network of the target user end, forms a FlexE time slot connection, and enables the LAG ports of the initiating user end and the target user end, and binds the two LAG ports to a warm standby group. At this point, the point-to-point full-course dedicated line channel between the initiating user and the target user is opened.

[0074] The above-mentioned opening process of the present invention also uses and establishes a point-to-multipoint network channel between an initiating user and multiple target users, and the implementation process is exactly the same.

[0075] Meanwhile, if the initiating user and the target user are in the same BNC-CP and BNC-UP, the process of generating the instant point-to-point network described in the present invention is relatively simplified. It only requires the BNC network service mall system to control the same group of BNC-CP to issue instructions to the same group of BNC-UP in the BNC network service mall system.

[0076] like Figure 5 As shown, the instant point-to-point network cancellation process includes: S3.1, the initiating user initiates a termination application to the BNC network business mall system through the client, or the BNC network business mall system initiates it automatically.

[0077] S3.2, the BNC network business mall system queries the initiating user's broadband line account and real-time point-to-point network business data, and sends a confirmation cancellation message to the user.

[0078] S3.3, after the user confirms the termination, the BNC network business mall system submits the termination confirmation to the BSS system.

[0079] S3.4, after the BSS system returns the cancellation confirmation, the BNC network service mall system sends a cancellation instruction of the instant point-to-point network to the AAA system and the RMS home gateway management system, and carries the original rate parameters of the user's broadband line account.

[0080] S3.5, the BNC network service mall system cancels the LAG and Flex ports of the bearer network where the initiating user and the target user are located through the BNC-CP where the initiating user and the target user are located to send instructions to the corresponding BNC-UP.

[0081] S3.6, the BNC network service mall system cancels the optical fiber broadband logic layer slice from the OLT device to the user's home gateway through the OSS system instructions corresponding to the initiating user and the target user.

[0082] S3.7, the BNC network service mall system instructs the RMS home gateway management system where the initiating user and the target user are located to delete the WAN port respectively.

[0083] The home gateway described in the present invention includes LAN upstream gateway and home router products, and also includes passive optical network PON upstream gateway and router products. The PON network covers Gigabit passive optical network GPON, Ethernet-based passive optical network EPON, 10G EPON, next NGPON (10G GPON and subsequent versions) and WDMPON, etc., and the specific implementation methods are completely consistent.
