Description

Technical Field

[0001] The present invention relates to the fields of cloud computing and network virtualization, and in particular to an IPv6 routing synchronization and high-availability scheduling system based on Neutron's BGP dynamic routing. Background Art

[0002] With the rapid development of information technology, cloud computing has become the core driving force for the digital transformation of enterprises. The flexibility, scalability and efficiency provided by cloud computing have made it widely used in various application scenarios, including big data processing, artificial intelligence, and the Internet of Things (IoT). In a cloud computing environment, the network is a key component for realizing resource virtualization and service delivery. OpenStack is an open cloud computing platform, and its Neutron module focuses on providing network services, allowing users to flexibly create and manage virtual networks through APIs.

[0003] In the cloud computing environment, the introduction of network virtualization technology makes the management of network resources more flexible and efficient. Virtual networks can be quickly configured and adjusted according to different application requirements, supporting multi-tenant isolation and resource sharing. However, with the complexity brought by network virtualization, traditional static routing methods can no longer meet dynamic and real-time network requirements. This has prompted the widespread application of dynamic routing protocols.

[0004] Border Gateway Protocol (BGP) is the core routing protocol in the Internet, mainly used for exchanging routing information between different autonomous systems. The dynamic routing characteristics of BGP make it of great application value in cloud computing environments, especially when real-time updates of network status are required.

[0005] In the cloud computing environment, with the popularization of virtualization technology and the promotion of IPv6, the demand for dynamic routing has become more urgent. The combination of BGP dynamic routing and IPv6 can effectively solve the following problems:

[0006] 1. Efficient routing management

[0007] The dynamic characteristics of BGP can reflect the changes of IPv6 addresses in real time, ensuring that the network traffic of virtual machines in the cloud computing environment can be routed to the correct destination in a timely manner. This is the basis for ensuring the quality of service for large-scale cloud platforms.

[0008] 2. Dealing with complex network topology

[0009] With the increasing number of cloud computing applications, network topology has become more complex. Dynamic routing can automatically adapt to changes in network topology, ensure network flexibility and scalability, and support the simultaneous operation of multiple tenants and multiple business scenarios.

[0010] 3. Improve resource utilization

[0011] Dynamic routing can effectively manage network traffic, reduce redundant routing and unnecessary network overhead, and improve resource utilization efficiency. For cloud service providers, this means higher economic benefits and lower operating costs.

[0012] In the cloud computing environment, the combination of dynamic routing and IPv6 is an inevitable trend in the future network development. The application of BGP dynamic routing will provide a solid foundation for the flexibility, high availability and reliability of cloud services, and will also promote the full deployment and application of IPv6. By continuously optimizing the network architecture and management mechanism, the cloud computing platform can better adapt to future challenges and opportunities. Summary of the invention

[0013] In order to solve the above technical problems, the present invention provides an IPv6 routing synchronization and high-availability scheduling system based on Neutron's BGP dynamic routing, which meets the strict requirements for flexibility and reliability in modern cloud computing environments by realizing efficient IPv6 routing synchronization and high-availability scheduling functions. By ensuring that the IPv6 address of the virtual machine can stably access the outbound traffic and improving the fault tolerance of the system through intelligent scheduling, the present invention not only optimizes the management of network resources, but also promotes the efficient operation of the cloud platform in a multi-tenant environment, and promotes the sustainable development of cloud computing and the widespread application of IPv6.
