Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to an end-to-end cross-machine fixed network service orchestration method. Background Art

[0002] At present, with the rapid development of communication technology, the communication network structure is becoming more and more complex, and the communication means and access means of fixed networks and mobile networks are increasing. Due to the requirements of security and confidentiality, different fixed networks are usually isolated from each other and communicate with each other in a controlled manner.

[0003] As the scale of the network increases, there is a need for interoperability between mobile network communication terminals and fixed network communication terminals. However, due to the complexity and isolation of the network, end-to-end service orchestration across mobile and fixed networks is difficult.

[0004] At present, it is usually realized by manual configuration by professional network managers. This method is complex and inefficient. It can be seen that there is a lack of an effective method in the prior art to orchestrate cross-machine fixed network services that can be managed and controlled. Summary of the invention

[0005] In view of this, the present invention proposes an end-to-end cross-machine fixed network service orchestration method. The present invention has the characteristics of universal method and convenient use, and is suitable for end-to-end cross-machine fixed network service orchestration.

[0006] The technical solution adopted by the present invention is:

[0007] An end-to-end cross-machine fixed network service orchestration method comprises the following steps:

[0008] (1) Initiate a network topology data synchronization request through the network topology collection module, and query network topology data information through the mobile network professional network management, fixed network professional network management, and inter-network exchange control system;

[0009] (2) The mobile network professional network management, fixed network professional network management, and inter-network switching control system actively register their own service orchestration policy control capabilities to the service orchestration capability registration module through the service orchestration capability registration interface. The service orchestration policy control capabilities include bandwidth limitation, delay limitation, jitter limitation, packet loss rate limitation, path optimization strategy, and primary and backup path capabilities. The service orchestration policy control capability is used as the input of the service cross-domain decomposition module to specify the service quality assurance strategy of the sub-service.

[0010] (3) The business demand receiving module realizes the manual input of end-to-end business demand, or receives the end-to-end business demand issued by the upper application system; analyzes the business demand and transmits the business demand to the business cross-domain decomposition module. The business cross-domain decomposition module plans a cross-network and cross-domain communication tunnel that meets the business demand based on the network topology data and the business arrangement strategy control capabilities of the mobile network professional network management and the fixed network professional network management; then, the business demand is decomposed according to different network domains, decomposed into the communication tunnels and inter-network data exchange strategies that need to be established for each network domain, that is, the sub-businesses that each professional network management needs to complete;

[0011] (4) The sub-service resource prediction module determines whether the current network meets the service requirements. The judgment includes: whether the remaining network bandwidth meets the service requirements, whether the network delay and packet loss parameters meet the service requirements, and whether the current policy conflicts with the existing policy. When all sub-services pass the resource prediction operation, it is considered that the current network environment has the conditions for opening the service and the sub-service can be issued. If there are sub-services that do not pass the resource prediction operation, it is considered that the current network environment does not have the conditions for opening the service. The service requirement adjustment module adjusts the service requirements and re-performs the cross-domain service decomposition and resource prediction after the adjustment.

[0012] (5) When all sub-services are determined by the resource pre-judgment operation to meet the resource requirements, the sub-service delivery operation is performed. The specific method is: the sub-service is delivered to the mobile network professional network management, the fixed network professional network management and the inter-network exchange control system through the collaborative control module. The professional network management performs the service orchestration in the domain and feeds back the orchestration results to the data collection module. The data collection module sends the domain orchestration results to the service orchestration result collection module to form an end-to-end service orchestration result.

[0013] (6) After the service is activated, the service operation quality monitoring module monitors the service operation indicators, including the real-time traffic, latency, jitter, and packet loss rate of the service. During the monitoring process, if the service operation quality does not meet the service requirements, the service demand adjustment module will be fed back to adjust the service requirements, re-decompose the service cross-domain and pre-judge the resources.

[0014] (7) After receiving the service termination instruction, the service demand receiving module sends it to the service cross-domain decomposition module. The service cross-domain decomposition module sends the service termination instruction to the mobile network professional network management, fixed network professional network management, and inter-network exchange management and control system through the collaborative control module to release the corresponding network resources and complete the service life cycle management and control.

[0015] Furthermore, in step (1), the network topology data includes information about nodes, devices, links and ports. The network topology data is used as input to the service cross-domain decomposition module to determine whether there is a reachable connectivity path between communication terminals during service orchestration.

[0016] Furthermore, in step (3), the cross-network and cross-domain communication tunnel includes communication tunnel requirement parameters within each participating network domain and policy requirement parameters for cross-network data exchange between network domains; the communication tunnel requirement parameters are used to ensure communication quality, and the policy requirement parameters are used to ensure isolation between different networks and limit whether data packets can pass;

[0017] Furthermore, the end-to-end service requirements include: source IP address, source service port, destination IP address, destination service port, bandwidth, delay, and jitter.

[0018] Furthermore, the communication tunnel requirement parameters include: communication bandwidth, communication priority, link optimization strategy, and link primary and backup strategy.

[0019] Furthermore, the policy requirement parameters include: whitelist information, blacklist information, source address information, destination address information, communication service port information, communication protocol type, and communication guarantee time.

[0020] Compared with the background technology, the present invention has the following advantages:

[0021] 1. The present invention proposes an end-to-end cross-mobile fixed network service orchestration method, which can effectively meet the service orchestration requirements across mobile networks and fixed networks.

[0022] 2. The present invention can complete business arrangement under the premise of ensuring network isolation by decomposing cross-domain tasks into communication tunnel requirements and cross-network data exchange strategies. After the business life cycle ends, the network can be restored to an isolated state.

[0023] 3. The present invention can specify orchestration strategies according to the business orchestration capabilities supported by each professional network domain through unified processing of network topology data and business orchestration capability registration functions. It can not only accurately control service assurance strategies, but also has a resource prediction mechanism, which can effectively improve the success rate of business orchestration and has good universality and scalability.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] An end-to-end cross-machine fixed network service orchestration method, the method first performs inter-domain routing, then decomposes the end-to-end cross-network and cross-domain service orchestration requirements into the intra-domain service orchestration requirements of each participating network domain, then plans the communication tunnel within the network domain, and creates an inter-network data exchange strategy, thereby completing the end-to-end service orchestration across the machine fixed network through coordination with various professional network managers.

[0028] Reference Figure 1 The method is mainly implemented as business collaboration arrangement software 11, including the following steps:

[0029] (1) Network topology information is the basis of service orchestration. The network topology collection module 1 in the service collaborative orchestration software 11 initiates a network topology data synchronization request to query the mobile network professional network management 14, the fixed network professional network management 12, and the network exchange control system 13 for network topology data information. The network topology data includes information such as nodes, devices, links, and ports. The network topology data is used as the input of the service cross-domain decomposition module 4 to determine whether there is a reachable connection path between communication terminals during service orchestration.

[0030] (2) The service coordination and orchestration software 11 opens a service orchestration capability registration interface to support the mobile network professional network management 14, the fixed network professional network management 12, and the inter-network switching management and control system 13 to actively register their own service orchestration policy control capabilities with the service orchestration capability registration module 2. The service orchestration policy control capabilities include bandwidth limitation, delay limitation, jitter limitation, packet loss rate limitation, path optimization strategy, and primary and backup path capabilities. The service orchestration policy control capability is used as an input to the service cross-domain decomposition module 4 to specify the service quality assurance strategy of the sub-service.

[0031] (3) The business collaborative orchestration software 11 provides end-to-end business demand manual input or receives end-to-end business demand issued by the upper application system through the business demand receiving module 3, analyzes the business demand, and transmits the business demand to the business cross-domain decomposition module 4. The business cross-domain decomposition module 4 plans a communication tunnel that meets the required business demand based on the full network topology data and the business orchestration capabilities of the mobile network professional network management 14 and the fixed network professional network management 12. A complete cross-network and cross-domain communication tunnel includes the communication tunnel requirement parameters within each participating network domain and the policy requirement parameters for cross-network data exchange between network domains. The communication tunnel requirement parameters are used to ensure the quality of communication, and the policy requirement parameters for cross-network data exchange are used to ensure the isolation between different networks and limit whether data packets can pass. The business demand is decomposed according to different network domains, and decomposed into the communication tunnels and inter-network data exchange policies that need to be established for each network domain, that is, the sub-businesses that each professional network management needs to complete.

[0032] Among them, end-to-end service requirements include: source IP address, source service port, destination IP address, destination service port, bandwidth, delay, jitter, etc.

[0033] The communication tunnel requirement parameters within each participating network domain include: communication bandwidth, communication priority, link optimization strategy, link primary and backup strategy, etc.

[0034] The policy requirement parameters responsible for cross-network data exchange between domains include: whitelist information, blacklist information, source address information, destination address information, communication service port information, communication protocol type, communication guarantee time, etc.

[0035] (4) End-to-end fixed network service orchestration requires the cooperation of service collaborative orchestration software 11 and fixed network professional network management 12, fixed network Internet management 13 and mobile network professional network management 14. Therefore, resource pre-judgment operation is required before issuing sub-service requirements to professional network management 15. Sub-service resource pre-judgment module 5 determines whether the current network meets the service requirements. The judgment content includes whether the remaining network bandwidth meets the service requirements, whether parameters such as network delay and packet loss meet the service requirements, and whether the current strategy conflicts with the existing strategy. When all sub-services pass the resource pre-judgment operation, it is considered that the current network environment has the conditions for opening the service, and the sub-service issuance operation can be performed. If there are sub-services that do not pass the resource pre-judgment operation, it is considered that the current network environment does not have the conditions for opening the service. The service demand adjustment module 7 adjusts the service demand, and after the adjustment, the cross-domain service decomposition and resource pre-judgment are re-performed.

[0036] (5) When all sub-services are determined to meet resource requirements by the resource pre-judgment operation, the sub-service delivery operation is performed. The sub-service is delivered to the corresponding professional network manager 15 through the collaborative control module 6. The professional network manager 15 performs service orchestration within the domain and feeds back the orchestration results to the data collection module 8. The data collection module 8 sends the domain orchestration results to the service orchestration result aggregation module 9, forming an end-to-end service orchestration result.

[0037] (6) After the service is activated, the service operation quality monitoring module 10 monitors the service operation indicators, including the real-time traffic, delay, jitter, packet loss rate and other information of the service. During the monitoring process, if the service operation quality does not meet the service requirements, it will be fed back to the service requirement adjustment module 7 to adjust the service requirements and re-perform service cross-domain decomposition and resource pre-judgment.

[0038] (7) After receiving the service end instruction, the service demand receiving module 3 sends it to the service cross-domain decomposition module 4. The service cross-domain decomposition module 4 sends the service end instruction to the professional network manager 15 through the collaborative control module 6 to release the corresponding network resources and complete the service life cycle management.

[0039] The above-mentioned embodiment uses a general software framework structure and a professional network management system that accesses mobile networks, fixed networks and inter-network data exchange to decompose the end-to-end cross-network and cross-domain business orchestration requirements into sub-business orchestration requirements for each participating network domain, plans the communication tunnel orchestration requirements within the network domain, creates an inter-network data exchange strategy, and ultimately completes end-to-end cross-machine fixed network business collaborative orchestration through the cooperation of business collaborative orchestration software and various professional network managers.

[0040] In summary, the present invention solves the difficulty of service orchestration between heterogeneous networks and isolated networks, and facilitates the full life cycle management of the orchestration, activation, adjustment and termination of end-to-end cross-machine fixed network services. The present invention has the characteristics of universal method and easy use, and is suitable for end-to-end cross-machine fixed network service orchestration.
