Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of port technology, and in particular, to a port resource allocation method, apparatus, device and storage medium. Background Art
[0002] With the development of computer networks, almost all walks of life have important connections with computer networks. Whether it is corporate office, commercial product promotion, or leisure life, they are all closely related to computer networks. The same is true in cloud computing scenarios. Cloud computing provides various services for external access, and cloud hosts can also be used as office computers to access external networks. In order to implement various cloud service-related businesses, multiple network elements are required to provide different traffic processing functions, such as stateless network elements providing EIP product services and stateful network elements providing NAT service product services.
[0003] Stateful network elements need to record access information by flow for NAT services, which is used to modify and restore NAT data. For example, when the client sends a request in the outbound direction, the network element creates a six-tuple of information for the outbound session record access, and creates an inbound session record for restoring NAT information. The return traffic is sent to the client, and finally forward and reverse access of the traffic is achieved. The six-tuple information in the outbound session includes sip, dip, sport, dport, protocol, and vni. Taking snat as an example, sip is the public network IP used for NAT, and sport is a target port on this public network IP. There are generally two solutions to obtain available sport information, port segmentation management and port global management. Port segmentation management is to evenly distribute the target ports of an IP according to the number of business threads. When a business thread creates a session, it can take one of the ports from the target port pool of the current thread. Port global management is to manage all the target ports of an IP in a unified manner, and each thread applies from the global port pool when applying.
[0004] However, in the above two methods, the utilization rate of port segment management is low. When the traffic distribution is uneven, port waste and port exhaustion may occur. The global port management performance is low, and there is performance loss caused by competition among multiple threads, which makes it impossible to improve port utilization and leads to traffic interruption.

[0060] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.
[0061] It should be noted that in the embodiments of the present application, reference is made to Figure 4 , 5 , 6. Port segmentation module, competition management module, and port borrowing module.
[0062] In addition, there is a port mapping module, that is, a port management solution that combines the advantages of global port management and port segmentation management in the embodiment of the present application, mainly including a port segmentation module, a port mapping module, a competition management module, and a port borrowing module. The four modules work together to fully utilize the NAT port.
[0063] Among them, refer to Figure 4 , port segmentation module, each NAT IP has 1-65535 available port resources, and the port segmentation module evenly distributes port resources according to the number of business threads, ensuring that the segment resources of each thread are basically consistent and the ports are continuous.
[0064] For example, if there are three business threads, the segmentation results are: thread 1 port segment: 1 to 21845; thread 2 port segment: 21846 to 43690; thread 3 port segment: 43691 to 65535.
[0065] Port mapping module, each thread has its own port mapping space, using bitmap mode. After the port application is completed, the corresponding bit is set, and the bit is cleared after the port is released. The bitmap offset of each thread starts from 0 to avoid memory waste. If the available bit applied by thread 1 is 0, the available port after mapping is 1 (the port range of thread 1 is 1-21845).
[0066] Therefore, the starting port of the thread plus the bit offset equals the actual available port.
[0067] Reference Figure 5,Content management module, each NAT IP has a thread-level contention management structure, which uses a spin lock mechanism to handle the port resource competition relationship within the thread. When accessing other thread port resources, the target thread port resources are locked, and the critical section resources are released after the access is completed.
[0068] When the resource is released, the target thread port resource continues to be locked, and the critical section resource is released after the access is completed.
[0069] Reference Figure 6 The port borrowing module only uses the port resources in the current thread when the port resources in the current thread are available. When the port resources in the thread are exhausted, the port borrowing function is automatically enabled to borrow ports from other available threads. After the port is released, it is recycled to the original thread. After the port borrowing mode is enabled, it cooperates with the competition management module to lock the critical area resources and realize multi-thread competition access control.
[0070] Therefore, based on the above four modules, the network element can process the service request, refer to Figure 7 During this period, the port allocation, management and use are carried out, please refer to the following explanation for details.
[0071] Figure 1 is a flow chart of the steps of a port resource allocation method provided by an embodiment of the present application, such as Figure 1 As shown, the method may include:
[0072] Step 101, when a service flow request is received, obtaining a network address translation IP address corresponding to the service flow request, wherein the network address translation IP address includes port resources allocated according to different service threads;
[0073] Further, when receiving a service traffic request, obtaining a network address translation IP address corresponding to the service traffic request includes:
[0074] When a service flow request is received, query the configuration information corresponding to the service flow request;
[0075] According to the configuration information, a network address translation IP address corresponding to the service traffic request is obtained.
[0076] It should be noted that in the embodiment of the present application, when a service traffic request is received, the system will first obtain the network address translation IP address (NAT IP address) corresponding to the request, which is not only used to identify the source or target of the request, but also includes port resources allocated according to different service threads. These port resources are used for port mapping during the NAT process to ensure that each service thread can independently manage and use its port resources, thereby achieving efficient network address translation and traffic processing.
[0077] Specifically, when a service traffic request is received, the system will first query the configuration information corresponding to the request. This configuration information may include NAT rules, port mapping policies, etc. Based on the queried configuration information, the system can obtain the network address translation IP address (NAT IP address) corresponding to the service traffic request. This NAT IP address is used to identify the source or destination of the request and is key information for port mapping during the NAT process. In this way, the system can ensure that each service traffic request can be correctly network-addressed, thereby achieving efficient traffic processing.
[0078] Step 102, when the service traffic request is in the first service thread, determining whether there is a target port in the port resource pool of the first service thread of the network address translation IP address;
[0079] It should be noted that in an embodiment of the present application, when a service flow request is in the first service thread, the system will first determine the network address translation IP address (NAT IP address) corresponding to the request. Then, the system will check the port resource pool of the first service thread of the NAT IP address to determine whether there is a target port therein. This process is to ensure that when processing a service flow request, an available port can be found for port mapping, thereby achieving network address translation. If the target port exists in the port resource pool, the system will use the port for subsequent processing; if not, the system will take other measures (such as borrowing port resources from other threads) to meet the request.
[0080] Step 103: If not, borrow the target port in the port resource pool of the second service thread of the network address translation IP address, and process the service traffic request through the target port of the second service thread.
[0081] If the target port does not exist in the port resource pool of the first business thread, the system will adopt a borrowing strategy. Specifically, the system will borrow the target port in the port resource pool of the second business thread associated with the network address translation IP address (NAT IP address). In this way, the system can ensure that business traffic requests are processed in a timely manner, even if the port resources of the first business thread are insufficient. After borrowing the port, the system will use the target port of the second business thread to process the business traffic request, thereby achieving efficient network address translation and traffic processing. This mechanism can improve resource utilization and ensure that the system can still run stably in high concurrency scenarios.
[0082] It should be noted that the second service thread may be any thread in the port segmentation module except the first thread, and is not limited to a specific thread.
[0083] Further, the borrowing of the target port in the port resource pool of the second service thread of the network address translation IP address and processing the service traffic request through the target port of the second service thread includes:
[0084] Searching whether the target port exists in the port resource pool of the second service thread of the network address translation IP address;
[0085] If so, the service traffic request is processed through the target port of the second service thread.
[0086] Further, searching for the target port in the port resource pool of the second service thread of the network address translation IP address includes:
[0087] If yes, locking the critical section when accessing the port resource pool of the second service thread;
[0088] A search is performed to determine whether the target port exists in the port resource pool of the second service thread of the network address translation IP address.
[0089] It should be noted that, for example, the first business thread of the port needs to access the port resources of the second business thread, the first business thread obtains the spin lock of the second business thread, locks the port resources of the second business thread, the first business thread checks the port resource pool of the second business thread, finds an available port resource, the first business thread uses the port resource and records it in the NAT table, the first business thread releases the spin lock of the second business thread, and allows other threads to access the port resources of the second business thread.
[0090] In addition, when the port resources are released, the first business thread releases a used port resource, the first business thread obtains the spin lock of the second business thread, locks the port resources of the second business thread, and the first business thread calculates the corresponding bit offset according to the port number, clears the corresponding bit (sets it to 0), indicating that the port has been released, and the first business thread releases the spin lock of the second business thread, allowing other threads to access the port of the second business thread.
[0091] Further, the processing of the service traffic request through the target port of the second service thread includes:
[0092] Setting an unused bit corresponding to the target port in a bitmap data structure;
[0093] The service traffic request is processed through the target port of the second service thread.
[0094] It should be noted that in the embodiment of the present application, when the network element receives a service flow request, it queries the relevant configuration and finds the relevant NAT IP to apply for port resources. When the port resources of this thread are available, it enters the port mapping module to apply for the port. When the port resources are not available, it enters the port borrowing module to query whether other threads have available resources. If available, it enters the contention management module, locks the thread critical section, and handles thread contention. Then it continues to perform port mapping of the borrowed thread and apply for an available port.
[0095] Therefore, in the process of applying for available ports, port mapping needs to be performed through the port mapping module.
[0096] Specifically, each thread has its own port mapping space, which means that each thread can manage and allocate port resources independently without interfering with each other. The port mapping space uses a bitmap data structure to represent the usage of the port. Each bit represents the state of a port (used or unused). For example, if the port range of a thread is 1 to 21845, the size of the bitmap will be 21845 bits.
[0097] Therefore, when a thread applies for a port, the port mapping module will find an unused bit in the bitmap and set it (to 1), indicating that the port is occupied. When the port is released, the corresponding bit will be cleared (set to 0), indicating that the port has been released.
[0098] In addition, in the embodiment of the present application, the bitmap offset of each thread starts from 0, which means that the first bit of the bitmap corresponds to the first port of the thread, and the calculation formula of the actual available port is the following formula 1:
[0099] Actual available port = thread start port + bit offset (Formula 1)
[0100] For example, if the starting port of thread 1 is 1 and the available bit requested is 0, then the actual available port is 1 (i.e. 1+0).
[0101] Further, after step 102, that is, after the step of determining whether there is a target port in the port resource pool of the first service thread of the network address translation IP address when the service traffic request is in the first service thread, the method includes:
[0102] If so, the service traffic request is processed through the target port of the first service thread.
[0103] Further, processing the service traffic request through the target port of the first service thread includes:
[0104] Setting an unused bit corresponding to the target port in a bitmap data structure;
[0105] The service traffic request is processed through the target port of the first service thread.
[0106] It should be noted that if the port resource corresponding to the current thread is available at the beginning, you can directly enter the port mapping module to apply for the port.
[0107] In addition, in an embodiment of the present application, the first-level distribution module inside the network element receives the service message data, and distributes it to the target service thread for service processing according to the five-tuple information or port segment information. After receiving the message, the service thread queries the service configuration according to the target IP, target port and other information, and performs basic data inspection. After the inspection is completed, the inbound and outbound session records are created. The port applied for in the outbound session record is completed by the port segmentation module, the port mapping module, the contention management module, and the port borrowing module. Finally, the outbound traffic performs the NAT service, and the return traffic returns to the client through the query session and reverse NAT recovery. Finally, normal traffic access is achieved.
[0108] In an embodiment of the present application, when a service traffic request is received, the network address translation IP address corresponding to the service traffic request is obtained, and the network address translation IP address includes port resources allocated according to different service threads; when the service traffic request is in the first service thread, it is determined whether there is a target port in the port resource pool of the first service thread of the network address translation IP address; if not, the target port in the port resource pool of the second service thread of the network address translation IP address is borrowed, and the service traffic request is processed through the target port of the second service thread. That is, the embodiment of the present application realizes efficient port resource management and allocation by allocating an independent port resource pool to each network address translation IP address and adopting a thread-level competition management mechanism. When the port resources of the first service thread are insufficient, the port resources of the second service thread can be dynamically borrowed to ensure that the service traffic request is processed in a timely manner, thereby improving the processing capacity and resource utilization of the network equipment and enhancing the stability and reliability of the system.
