The invention discloses an ALG (Application Layer Gateway) processing method and device, electronic equipment and a storage medium. The method comprises the steps that a control channel session table corresponding to a first message is detected, the control channel session table is used for recording a message load content length change difference value before and after a preset type of message is subjected to target conversion, and the preset type of message is a multi-channel protocol negotiation message based on a transmission control protocol; the target conversion is ALG application layer message information analysis and address conversion performed when passing through an NAT (Network Address Translation) router; determining a second message according to the type of the first message and a control channel session table corresponding to the first message, wherein the second message is a subsequent message which correspondingly needs to be forwarded after the first message; and carrying out forwarding processing on the second message. According to the technical scheme, the problem that the serial number operation consumption of the subsequent message after TCP message conversion in the NAT ALG scene is large is solved.

Systems and methods are described for providing an application-level gateway that allows computing devices to utilize an on-demand network code execution system. An on-demand network code execution system may allow users to submit code to be executed in a serverless environment, and may provide an interface for executing the user-submitted code on demand. The interface may require that users authenticate, provide input in a particular format, or meet other criteria when sending a request to execute the code. An application-level gateway may thus provide an interface that implements these functions, thereby allowing computing devices to interact with the code as though it were running on a server (e.g., by using the Hypertext Transport Protocol). The application-level gateway may also use on-demand code execution to provide load balancing for servers that are running the user-submitted code, and seamlessly provide access to code that runs on both server-based and serverless environments.

The method can be widely applied to visual quality control of geophysical prospecting data.

The invention relates to the technical field of logistics transportation industry, in particular to a loss assessment method and system based on a multi-modal large model, an AI Agent and an RAG. Although simple image recognition or a rule engine is used for loss assessment in a claim settlement loss assessment process for abnormal conditions such as goods damage and loss in the traditional logistics transportation industry, the intelligent degree is low, and ever-changing actual cases are difficult to deal with. The loss assessment system comprises a front-end application layer, an API gateway layer, a core processing engine layer, a capability component layer and a data and infrastructure layer, and the loss assessment method mainly comprises the steps of case input and evidence uploading; a step of task triggering and Agent scheduling; and a step of RAG knowledge enhancement. According to the method, the efficiency is greatly improved, the judgment standard is unified, the decision process is transparent and traceable, evolution and learning are continued, and the whole system is more intelligent through the RAG mechanism.

The invention relates to the technical field of network communication, in particular to a message processing method and device based on an application layer gateway, equipment and a medium. The method comprises the following steps: when an IP message to be processed is detected, determining a forwarding state of the IP message, determining tuple parameter information under the condition that the forwarding state is to be forwarded and the message transmission direction is uplink, and matching the tuple parameter information with a preset access control configuration blacklist to the IP message, and matching the tuple parameter information in a preset forwarding rule table under the condition that the tuple parameter information is not hit, and forwarding the IP message according to a matching result. According to the invention, the dependence of the gateway function on a specific system or hardware is solved, any network interface on the support equipment can be flexibly configured as the WAN port or the LAN port, and any IP address can be designated as the IP address of the WAN port, so that the purposes of simplifying the gateway configuration process and reducing the configuration difficulty are achieved, and the functionality and flexibility of the gateway are improved at the same time.

The present application provides a cross-cluster application access method, a gateway apparatus, and a related product, capable of realizing communication between cross-cluster applications and reducing the resource occupation of a network proxy component in a cluster. The method is applied to a multi-cluster system, the multi-cluster system comprises an application layer gateway, a first K8s cluster and a second K8s cluster, the first K8s cluster comprises a network proxy component and a first application, and the second K8s cluster comprises a second application. Specifically, the network proxy component intercepts an access request sent by the first application, and forwards the access request on the basis of a routing rule matching the request. When the routing rule instructs to perform application layer processing on the access request, the access request is sent to the application layer gateway, so that the application layer gateway performs application layer processing on the access request, and forwards the processed access request to the second application. When the routing rule instructs to perform transport layer processing on the access request, the access request is sent to the second application.
