[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0044] Network Function Virtualization (NFV) can provide a flexible and controllable network function platform to reduce the economic cost and operation and maintenance cost of the network.

[0045] In some related technologies, the NFV platform can be a three-layer architecture, for example, AWS HyperPlane NFV platform. The first layer is Top, which is used to establish network connections. Forwarding can be completed at the Top layer. The second layer is Flow Master, which is used to record network connection information. The third layer is Decider, which is used to implement network functions. For the Network Address Translation (NAT) function, Internet Protocol (IP) and transport layer port conversion are required.

[0046] In other related technologies, the NFV platform can be a two-layer architecture, including a session layer and a forwarding layer. The session layer, also known as the slow path (SP), is responsible for the implementation of business logic, creating and caching session information according to business requests; the forwarding layer, also known as the fast path (FP), forwards business traffic according to session information. It is stateless, and the number of cluster nodes can be horizontally expanded according to business needs. The session layer adopts the active-standby mode, and the forwarding layer adopts the distributed cluster deployment mode, and the session layer and the forwarding layer are deployed in different network elements respectively.

[0047] In the related art, whether it is a three-layer or two-layer architecture, network connection delays are prone to occur during data transmission due to the long forwarding path, the new network connection performance is poor, and more computing resources are consumed. To solve the above technical problems, the embodiments of the present invention provide an information processing method, apparatus and related equipment.

[0048] See also Figure 1 , Figure 1 is one of the flow charts of an information processing method provided by an embodiment of the present invention, which is applied to a network function virtualization platform, wherein the platform includes multiple network elements, and each network element includes a fast path FP module and a distributed slow path DSP module, such as Figure 1 As shown, the method comprises the following steps:

[0049] Step 101: When a first network element among the multiple network elements receives request information and session information corresponding to the request information is not found in a fast forwarding table of the first network element, the DSP module of the first network element is used to obtain session information corresponding to the request information;

[0050] In one example, for a cloud network NFV scenario, multiple network elements are set, each of which includes a fast path FP module and a distributed slow path (Distribution Slow Path, DSP) module, and each network element can be recorded as an FP-DSP network element, that is, an FD network element. The FP module is used to quickly forward the information to be processed, and the DSP module is used to build a fast forwarding table.

[0051] The first network element may be any network element among multiple FD network elements. When the first network element receives the request information, in the first network element, the FP module queries the request information based on the fast-forward table constructed by the DSP module. When the session information corresponding to the request information is not found in the fast-forward table, the session information corresponding to the request information may be obtained based on the DSP module of the first network element. Among them, there may be multiple ways to obtain the session information corresponding to the request information based on the DSP module of the first network element. For example, the DSP module of the first network element may create session information corresponding to the request information; the DSP module of the first network element may obtain session information corresponding to the request information from other network elements; the DSP module of the first network element may obtain session information corresponding to the request information from the Session Recovery (SR) module, and the SR module backs up the fast-forward tables created by the DSP modules of multiple network elements respectively.

[0052] In this example, the slow path is deployed in a distributed manner, and the fast path and the distributed slow path are modularized and deployed in the same network element. In other words, the same FD network element includes FP modules and DSP modules. This reduces the forwarding paths in the data transmission process, improves information forwarding efficiency, and reduces network connection delays.

[0053] Step 102: The FP module of the first network element forwards the message information corresponding to the request information based on the session information corresponding to the request information.

[0054] The message information may be a Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) message. The first network element may perform port address translation (PAT) on the message information to allow multiple devices to use the same public IP address on the internal network for Internet communication, but each connection may be distinguished by a different port number.

[0055] In the embodiment of the present invention, the FP module and the DSP module are deployed in the same network element, which reduces the communication between network elements. When the first network element among multiple network elements receives the request information, and the session information corresponding to the request information is not found in the fast forwarding table of the first network element, the DSP module of the first network element obtains the session information corresponding to the request information; the FP module of the first network element forwards the message information corresponding to the request information based on the session information corresponding to the request information. The forwarding path in the data transmission process is reduced, the information forwarding efficiency is improved, and the network connection delay is reduced.

[0056] Optionally, the DSP module based on the first network element obtains session information corresponding to the request information, including:

[0057] Obtaining local port information corresponding to the request information;

[0058] Based on the local port information and a preset global port mapping table, determining a second network element from the multiple network elements, wherein the fast forwarding table of the second network element includes session information corresponding to the request information;

[0059] Determining network element status information of the second network element;

[0060] When the network element status information indicates that the second network element is in an available state, the DSP module of the first network element receives the session information corresponding to the request information sent by the DSP module of the second network element.

[0061] In some optional embodiments, each network element may store a pre-set global port mapping table (GPMT), which includes a network element identifier (ID), network element status information, network element IP, and a port list. The network element ID of each network element may be a continuous number starting from 0; the network element status information may include an available state (Active), an unavailable state (Inactive), and a deleted state (Deleting); the network element IP is used for communication between network elements; each port can only appear in one port list, and each network element can use its own port list to allocate ports.

[0062] like Figure 2As shown, in this example, ① when the first network element receives the request information, in the first network element, the FP module queries the request information based on the fast-forward table constructed by the DSP module. When the session information corresponding to the request information is not found in the fast-forward table of the first network element, that is, when the message fails to query the session in the FP module of the first network element, the local port information (local port) corresponding to the request information is obtained. ② Based on the local port and GPMT, the second network element is determined from multiple network elements, and the fast-forward table of the second network element includes the session information corresponding to the request information; when it is determined that the network element status information of the second network element indicates that the second network element is in an available state (that is, the network element status information of the second network element is Active), the DSP module of the first network element receives the session information corresponding to the request information sent by the DSP module of the second network element. Specifically, the target DSP module can be determined based on GPMT and the local port corresponding to the request information. The target DSP module is the DSP module of the second network element. The DSP module of the second network element performs two actions at the same time: ③ The message information corresponding to the request information is handed over to the FP module of the second network element, and the message is forwarded through the FP module of the second network element; ④ The session information corresponding to the request information is sent to the DSP module of the first network element, and the DSP module of the first network element establishes a fast forwarding table associated with the current session information to quickly forward subsequent messages and improve the message forwarding efficiency.

[0063] After the configuration of each network element is completed, a local IP address table will be generated. The IP in the local IP address table can be the local IP configured by the server load balancing (SLB) network element or the public IP address of the NAT network element. If the destination IP corresponding to the request information is in the local IP address table, the local port is the destination port of the request information. After obtaining the local port corresponding to the request information, the network element ID corresponding to the local port can be searched in GPMT, so that the second network element can be determined among multiple network elements.

[0064] In this way, the DSP module of the first network element obtains the session information corresponding to the request information from the DSP module of the second network element, and establishes a fast forwarding table associated with the current session information to quickly forward subsequent messages, thereby improving the message forwarding efficiency; and locates the message session to create a network element based on the destination IP and port, thereby improving the efficiency of querying the second network element, reducing network connection delays, and improving the performance of new network connections; at the same time, reducing the computing resources required to be consumed.

[0065] Optionally, the platform further includes a session recovery SR module;

[0066] After determining the network element status information of the second network element, the method further includes:

[0067] When the network element status information indicates that the second network element is in an unavailable state, the DSP module of the first network element receives the session information corresponding to the request information sent by the SR module.

[0068] In some optional embodiments, a session recovery (SR) module is also provided. The SR module is used to restore the session when an abnormality occurs in a certain network element, so that the platform has high availability. The SR module can be integrated in a certain network element among multiple network elements, or deployed in the NFV architecture.

[0069] like Figure 3 As shown, in this example, ① when the first network element receives the request information, in the first network element, the FP module queries the request information based on the fast forwarding table constructed by the DSP module. When the session information corresponding to the request information is not found in the fast forwarding table of the first network element, that is, when the message fails to query the session in the FP module of the first network element, the local port corresponding to the request information is obtained. ② Based on the local port and GPMT, the second network element is determined from multiple network elements. When it is determined that the network element status information of the second network element indicates that the second network element is in an unavailable state (that is, the network element status information of the second network element is Inactive), the DSP module of the first network element receives the session information corresponding to the request information sent by the SR module. ③ The DSP module of the first network element establishes a fast forwarding table associated with the current session information based on the session information sent by the SR module. ④ The message information corresponding to the request information is forwarded through the FP module of the first network element.

[0070] In this way, the DSP module of the first network element obtains the backup session information corresponding to the request information from the SR module to quickly forward subsequent messages, thereby improving the message forwarding efficiency; and, when there is an abnormality in the second network element, causing the second network element to be unavailable, the SR module can be set to restore the session, thereby reducing the network connection failure and improving the performance of the network connection.

[0071] Optionally, the DSP module based on the first network element obtains session information corresponding to the request information, including:

[0072] The DSP module of the first network element creates session information corresponding to the request information.

[0073] like Figure 4As shown, in this example, ① when the first network element receives the request information, in the first network element, the FP module queries the request information based on the fast-forward table constructed by the DSP module. ② When the session information corresponding to the request information is not found in the fast-forward table of the first network element, that is, when the message fails to query the session in the FP module of the first network element, the session information corresponding to the request information can be created based on the DSP module of the first network element. Afterwards, the DSP module of the first network element performs two actions simultaneously: ③ The message information corresponding to the request information is handed over to the FP module of the first network element, and the message is forwarded through the FP module of the first network element; ④ The session information corresponding to the request information is sent to the SR module to create the current session backup information in the SR module.

[0074] In this way, the DSP module of the first network element creates session information corresponding to the request information to quickly forward subsequent messages, thereby improving the message forwarding efficiency; and, when there is an abnormality in the first network element, causing the first network element to be unavailable, the session can be restored by setting the SR module, thereby reducing the number of network connection failures and improving the performance of the network connection.

[0075] Optionally, the FP module of the first network element forwards the message information corresponding to the request information based on the session information corresponding to the request information, including:

[0076] The DSP module of the first network element updates the fast forwarding table of the first network element based on the session information corresponding to the request information to obtain a target fast forwarding table;

[0077] The FP module of the first network element forwards the message information corresponding to the request information based on the target fast forwarding table.

[0078] In this embodiment, when the first network element receives the request information, in the first network element, the FP module queries the request information based on the first fast-forward table constructed by the DSP module. When the session information corresponding to the request information is not found in the first fast-forward table, the session information corresponding to the request information can be obtained based on the DSP module of the first network element. Among them, there can be multiple ways to obtain the session information corresponding to the request information based on the DSP module of the first network element. For example, the DSP module of the first network element can create session information corresponding to the request information; the DSP module of the first network element can obtain session information corresponding to the request information from other network elements; the DSP module of the first network element can obtain session information corresponding to the request information from the SR module. Please refer to the above content for details, which will not be repeated here.

[0079] In one example, after the first network element obtains the session information corresponding to the request information, the DSP module of the first network element can update the first fast forward table based on the session information corresponding to the request information to obtain the target fast forward table. In another example, after the first network element obtains the session information corresponding to the request information, the DSP module of the first network element can also directly establish the target fast forward table based on the session information corresponding to the request information.

[0080] Then, the FP module of the first network element forwards the corresponding message information of the request information based on the target fast forwarding table, which improves the forwarding efficiency of the first network element for subsequent messages; and the first network element can store the target fast forwarding table in the SR module, which is convenient for other network elements to obtain the target fast forwarding table, and also improves the forwarding efficiency of other network elements for related messages. Thereby improving the efficiency of the NFV platform and making the platform more robust.

[0081] Optionally, the method further comprises:

[0082] When a first network element among the multiple network elements receives the request information and session information corresponding to the request information is queried in the fast forwarding table of the first network element, message information corresponding to the request information is forwarded based on the fast forwarding table of the first network element.

[0083] like Figure 5 As shown, in this example, ① when the first network element receives the request information, in the first network element, the FP module queries the request information based on the fast forwarding table constructed by the DSP module. ② When the session information corresponding to the request information is queried in the fast forwarding table of the first network element, that is, when the message successfully queries the session in the FP module of the first network element, the message information corresponding to the request information is forwarded based on the FP module of the first network element. In this way, the FP module and the DSP module are deployed in the same network element, which reduces the communication between network elements. The forwarding path in the data transmission process is reduced, the information forwarding efficiency is improved, and the network connection delay is reduced.

[0084] Optionally, the platform further includes a network element controller, and the network element controller is used to add or delete network elements.

[0085] In some optional examples, network elements can be added (or expanded) through the network element controller to meet the forwarding requirements of greater traffic. Figure 6 As shown, the following steps may be specifically included:

[0086] ① The NE controller creates a new NE and assigns a NE ID; ② Generates a new global port mapping table (GPMT), the NE status of the newly added NE is inactive, and sends the GPMT to each NE (in order to avoid synchronization of existing NE sessions, the port list of existing NEs is only reduced but not increased); ③ Based on the new GPMT, the new NE requests session synchronization from the SR module; ④ The SR module synchronizes the session to the newly added NE; ⑤ After the synchronization is completed, the NE controller is notified; ⑥ The NE controller updates the GPMT table, changes the NE status of the newly added NE to active, and sends it to all NEs; ⑦ Enables the NE and directs traffic to the new FD NE.

[0087] In some optional examples, the network element controller may delete (or shrink) the network element to reduce the waste of resources. Figure 7 As shown, the following steps may be specifically included:

[0088] ① The NE controller updates GPMT: the state of the NE being reduced is deleting, and is sent to each NE; ② Switch traffic; ③ Delete the NE. The state represented by the ID of the reduced NE can remain deleting until it can be reused for the next expansion. This improves the utilization of CPU resources.
