Description

Technical Field

[0001] The present invention relates to the technical field of cloud computing, and particularly to a method and system for implementing elastic public network IP shared bandwidth based on cloud computing. Background Art

[0002] The rapid development of Internet technology has greatly reshaped our daily life, learning methods, work patterns and entertainment activities, triggering profound changes in many traditional industries. With the continuous emergence of Internet applications and the increase in their complexity, the demand for computing resources has also risen sharply. This surge in demand poses challenges to the traditional data center model, because to meet the growing computing needs, more high-performance servers need to be continuously purchased, which not only increases the economic cost but also raises the industry threshold. At the same time, the operation and maintenance costs of data centers are also rising rapidly, and the limitations of traditional data centers become particularly obvious when dealing with failures. For example, in the server architecture of online games, once a server fails, manual intervention is required for switching or waiting for repair, which seriously affects the smooth operation of the game.

[0003] In this context, cloud computing emerged as an innovative solution. With the wide adoption of cloud computing, how to ensure that cloud resources can obtain stable public network access has become an urgent problem to be solved. Although traditional hardware firewalls can provide solutions, their operation process is complex. At the same time, the demand for network resources by different cloud resources usually varies at the same time.

[0058] Embodiment 2, based on Embodiment 1, proposes an implementation system for an elastic public network IP shared bandwidth implementation method based on cloud computing, including: a system management component, a service management component, and a monitoring and disaster recovery component. As Figure 1 。

[0059] The system management component is the basic functional component of the present invention, responsible for deploying the elastic public network IP service system and the shared bandwidth service system in the cloud computing platform. It is also responsible for the data backup work of the system.

[0060] The specific functions are as follows:

[0061] (1) Service deployment module: This module realizes the automated deployment function of the elastic public network IP service system and the shared bandwidth service system. This module will automatically create an elastic public network IP management node, a shared bandwidth management node, and an EIP cluster node on the cloud computing platform. Among them, the elastic public network IP management node and the shared bandwidth management node are deployed in the control network; the EIP cluster node is deployed in the management network and the business network. As Figure 2 。

[0062] (2) Data backup module: This module realizes the data backup function of the elastic public network IP service and the shared bandwidth service. Multiple backup methods such as manual backup, scheduled automatic backup, and automatic backup after important operations can be selected to back up the management data in the above management nodes and the business data in the EIP cluster nodes.

[0063] The service management component is the core functional module of the present invention, aiming to provide users with perfect elastic public network IP services and shared bandwidth services. This component consists of three sub-modules: an elastic public network IP module, a shared bandwidth module, and a bottom-layer communication module. Among them, the functions of the elastic public network IP module are managed by the elastic public network IP management node; the functions of the shared bandwidth module are managed by the shared bandwidth management node; the functions of the bottom-layer communication module are implemented by the EIP cluster node.

[0064] The specific functions are as follows:

[0065] (1) Elastic Public IP Module: This module is responsible for the user interaction of the Elastic Public IP service. Users manage Elastic Public IPs by operating the Elastic Public IP management node, and further distribute the service configurations of Elastic Public IPs to the EIP cluster nodes, thus realizing the network communication function of the cloud computing platform. For example, Figure 3 , it includes the following functions:

[0066] 1) Instance management function: Users can manage Elastic Public IP instances through this function. Users can create Elastic Public IP instances according to their needs (including specifying IP addresses, setting bandwidth values, etc.), and perform operations such as querying, deleting, and modifying bandwidth values on the instances.

[0067] 2) Service management function: Users can manage the service configurations of Elastic Public IPs through this function. Users can bind Elastic Public IPs to cloud servers that need to communicate over the public network, or unbind Elastic Public IPs that have been bound to cloud servers. The system distributes the service configurations of Elastic Public IPs to the EIP cluster nodes, and the EIP cluster nodes provide the underlying communication function.

[0068] 3) Data monitoring function: Users can monitor Elastic Public IP instances in real time through this module. Users can view the real-time monitoring data of Elastic Public IPs, including outbound traffic, inbound traffic, total number of outbound packets, total number of inbound packets, bandwidth usage ratio, etc.

[0069] (2) Shared Bandwidth Module: This module is responsible for the user interaction of the shared bandwidth service. Users manage shared bandwidth by operating the shared bandwidth management node, and further distribute the service configurations of shared bandwidth to the EIP cluster nodes, thus realizing the actual service function of the shared bandwidth service. For example, Figure 4 , it includes the following functions:

[0070] 1) Instance management function: Users can manage shared bandwidth instances through this function. Users can create shared bandwidth instances according to their needs (mainly setting bandwidth values, etc.), and perform operations such as querying, deleting, and modifying bandwidth values on the instances.

[0071] 2) Business management function: Users can manage the service configuration of shared bandwidth through this function. Users can add the Elastic Public IP instances created by the Elastic Public IP module to the created shared bandwidth instance, or remove the Elastic Public IP instances that have been added to the shared bandwidth from the shared bandwidth. The bandwidth value configuration of the Elastic Public IP instances added to the shared bandwidth will become invalid, and instead share the network bandwidth value of the same shared bandwidth instance with other Elastic Public IP instances belonging to the same shared bandwidth instance. Further, users can also make individual configurations for a certain Elastic Public IP instance belonging to the shared bandwidth instance to limit the maximum or minimum bandwidth value that it can use, so as to prevent a single Elastic Public IP instance within the shared bandwidth from occupying too much bandwidth.

[0072] 3) Data monitoring function: Users can monitor the shared bandwidth instance in real time through this module. Users can view the real-time monitoring data of the shared bandwidth instance, including outbound traffic, inbound traffic, total number of outbound packets, total number of inbound packets, bandwidth usage ratio, etc.

[0073] (3) Underlying communication module: This module is the business core of the Elastic Public IP service and the shared bandwidth service. According to the commands issued by users on the management node, it configures the Elastic Public IP or the shared bandwidth on the EIP cluster nodes, so as to meet the public network access requirements of the cloud computing platform. Such as Figure 5 , provides the following functions:

[0074] 1) NAT mapping function: According to the commands issued by the Elastic Public IP management node, it performs NAT conversion on the Elastic Public IP (i.e., EIP) and the floating IP (i.e., FIP) of the cloud computing resources, so as to realize the public network access of the cloud computing resources. Such as Figure 6 .

[0075] 2) Qos rate limiting function: According to the bandwidth values set for the Elastic Public IP instances or the shared bandwidth instances by the Elastic Public IP management node or the shared bandwidth management node, it performs Qos rate limiting on the Elastic Public IP instances or the shared bandwidth instances, so as to realize the bandwidth limiting ability of the cloud computing platform network communication.

[0076] The monitoring and disaster recovery component is an important part of the present invention. It provides strong support for the Elastic Public IP shared bandwidth system to ensure the stability and reliability of the system. This component includes the following three key modules:

[0077] The specific functions are as follows:

[0078] (1) Real-time Monitoring Module: The real-time monitoring module is the guardian for the normal operation of the system. It is responsible for real-time monitoring of the operating status of the Elastic Public Network IP management node, the shared bandwidth management node, and the EIP cluster node, including but not limited to resource usage, response time, and system load. Users can obtain detailed server operation reports through this module, so as to have an intuitive understanding of the health status of the system.

[0079] (2) Fault Alarm Module: The fault alarm module is the early warning system of the system. When the real-time monitoring module detects a fault in the Elastic Public Network IP management node, the shared bandwidth management node, or the EIP cluster node, such as server downtime or network anomaly, or the monitoring metrics exceed the preset warning line, this module will immediately send alarm information to the system administrator and relevant personnel. The alarm can be carried out in various ways, including but not limited to emails, text messages, phone calls, etc., to ensure timely notification and response.

[0080] (3) Disaster Recovery and Switching Module: The disaster recovery and switching module provides the system with the ability to quickly troubleshoot. When the system encounters abnormal situations such as service interruption, this module can quickly execute the disaster recovery and switching strategy. For the faulty management node or EIP cluster node, the module will adopt the latest backup information to restart a new node to take over the service, so as to achieve the quick troubleshooting of the elastic public network IP shared bandwidth system.

[0081] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
