Description

Technical Field

[0001] The present invention relates to the technical field of computer networks, and specifically provides a service gateway and a deployment method and device. Background Art

[0002] Computing network has emerged as a new type of technical research topic, aiming to solve the problem of coordinated scheduling of ubiquitous computing power and network. At present, most research results and technical solutions introduce computing routing protocols on the routing and forwarding equipment of the bearer network to support the notification of computing information, and use Layer 3 and Layer 4 destination address redirection and address port translation (DNAT) to schedule service traffic to the appropriate computing node.

[0003] This type of computing power information often only contains the resource status data of the computing power nodes, but does not include the status data and performance data of the service layer. In actual application scenarios, the computing power information may be normal but the service may be unavailable due to failure of the service component, causing serious reliability problems.

[0004] In addition, the traffic scheduling mechanism based on DNAT uses flow as the scheduling unit, which has a coarse granularity and is difficult to distinguish different segmented services and businesses in the same flow to perform accurate scheduling; since the service status is not perceived, session stickiness relies on the flow table aging mechanism to achieve, which has poor flexibility.

[0005] Therefore, it is urgent to improve the functionality, flexibility and reliability of the computing network by supporting the service layer reverse proxy function.

[0006] In the current computing network, service traffic scheduling and load distribution are generally implemented based on DNAT, and the metrics used for scheduling depend on the resource status data of the computing nodes, resulting in coarse granularity and inaccurate scheduling of service traffic. Summary of the invention

[0007] The present invention aims at the above-mentioned deficiencies of the prior art and provides a service gateway and a deployment method with strong practicality.

[0008] A further technical task of the present invention is to provide a service gateway and deployment device that is reasonably designed, safe and applicable.

[0009] The technical solution adopted by the present invention to solve its technical problem is:

[0010] A service gateway and deployment method, the method is used for a computing network, the service gateway has at least three logical network interfaces, namely a control plane interface, a user side interface and a service side interface;

[0011] The control plane interface is responsible for connecting with the control function entity to obtain service configuration information;

[0012] The user-side interface load is connected to the user access network to receive service requests from users;

[0013] The service side interface is responsible for connecting to the computing power service node through an IP bearer network or a bearer network based on SRv6 or MPLS, periodically checking the service status, and distributing service requests from users to the computing power service node.

[0014] Further, the specific steps are as follows:

[0015] S1. The service gateway obtains service configuration information of multiple computing service nodes from the control plane through the control plane interface;

[0016] S2, the service gateway carries the data connection of the service layer reverse proxy session on the service side interface;

[0017] S3. Check the health status and performance status of the computing power service node based on the service detection time of the above service configuration information;

[0018] S4. When the user-side interface receives a service request from the user, the service request from the user is forwarded to the computing power service node.

[0019] Furthermore, in step S1, the service configuration information includes the computing power service node IP address, protocol and port number, service URL information, associated data plane tunnel information and service detection time interval information, and is stored locally to form a service information table.

[0020] Furthermore, in step S2, based on the computing power service node IP address and the associated data plane tunnel information in the above service configuration information, the service gateway uses SRv6, MPLS or IPSec protocol on the service side interface to establish and maintain a data plane forwarding tunnel with the computing power service node, which is used to carry the data connection of the service layer reverse proxy session.

[0021] Further, in step S3, after establishing the above-mentioned data plane forwarding tunnel, the service gateway establishes a reverse proxy session connection with the computing power service node based on the computing power service node IP address, protocol and port number, and service URL information in the above-mentioned service configuration information, and periodically checks the health status and performance status of the computing power service node based on the service detection time interval in the above-mentioned service configuration information;

[0022] The health and performance status data will be stored in the service information table and associated with the corresponding computing service node.

[0023] Furthermore, in step S4, when the user-side interface receives a service request from the user, the service gateway retrieves the service information table, searches for the computing power service node associated with the requested target service, and filters the health and performance status data associated with these computing power service nodes based on the preconfigured load balancing strategy, and selects and forwards the service request from the user to the computing power service node through the above-mentioned data plane forwarding tunnel.

[0024] Further, in step S4, the service gateway is deployed at the user access network egress side, including the DN egress side of the mobile network UPF or P-GW, or the broadband network BRAS device egress side;

[0025] Configuring the user-side interface of the service gateway as an anycast address, and configuring a diversion strategy or a routing strategy for the anycast address on the user access network side;

[0026] The DNS resolution result of the service domain name of the service gateway proxy is statically configured as an anycast address.

[0027] A service gateway and deployment device, comprising: at least one memory and at least one processor;

[0028] The at least one memory is used to store a machine-readable program;

[0029] The at least one processor is used to call the machine-readable program to execute a service gateway and deployment method and device.

[0030] Compared with the prior art, the service gateway and deployment method and device of the present invention have the following outstanding beneficial effects:

[0031] The present invention can realize fine-grained accurate service traffic scheduling and ensure service continuity during node switching, while ensuring that user service requests are always routed nearby with low latency. BRIEF DESCRIPTION OF THE DRAWINGS
