Description

User-based traffic diversion method and device Technical Field

[0001] The present invention relates to the field of data communication technology, and in particular to a user-based traffic diversion method and device. Background Art

[0002] With the advent of the 5G and Internet of Things era, the Internet Protocol Version 6 segment IPv6, as the basic protocol, has also ushered in rapid development. The SRv6 Policy based on IPv6 has been planned and deployed in different user networks with its unique technical advantages. Internet Protocol Version 6 Segment Routing (SRv6) technology defines traffic steering rules and path selection. It achieves traffic steering and service links by mapping the SRv6 path identifier in the extension header of the IPv6 data packet to the nodes on the network path. Internet Protocol Version 6 Segment Routing Traffic Engineering Policy (SRv6-TE Policy) is a new tunnel diversion technology developed based on SRv6 technology. It provides users with functions such as path selection, path switching, and backup protection during traffic forwarding. It can also be used in combination with other network technologies and protocols (such as BGP, IS-IS, OSPF, etc.) to meet more complex network deployment and management needs.

[0003] In related technologies, when there are multiple forwarding paths corresponding to SRv6 TE Policies between a source node and a destination node, the headend device (i.e., the first node in the forwarding path) can select a target SRv6-TE Policy based on the Differentiated Services Code Point (DSCP) value in the tag field of the Layer 3 header of the message to be forwarded.

[0004] For example, the invention patent with publication number CN106204112A discloses a traffic diversion method and system based on user consumption sharing, including: the channel merchant server uses the exclusive channel identifier and the network address of the live broadcast platform to form a promotion link and push it to the channel merchant front end; when the user clicks the promotion link, the client jumps to the live broadcast platform front end corresponding to the promotion link; during a session between the client and the live broadcast platform front end, the live broadcast platform front end attaches the current channel identifier to all links visited by the user; when the user makes a consumption behavior during the current session, the live broadcast platform server records the current consumption behavior information and associates it with the current channel identifier.

[0005] For example, the invention patent with publication number CN107087017B discloses a method and device for business diversion, including: for a target business, obtaining historical behavior data of users who use the target business; analyzing the historical behavior data to obtain user characteristics of target users for limiting business diversion; selecting users who meet the user characteristics from users who do not use the target business as the target users; and sending business diversion information to the target users to guide the target users to use the target business.

[0006] However, in the process of implementing the technical solutions of the embodiments of the present application, the inventors of the present application discovered that the above technology has at least the following technical problems:

[0007] In the existing technology, SRv6-TE Policy technology is used to select a target SRv6-TE Policy from multiple SRv6-TE Policies to achieve communication between users, or the selection is made based on the 802.1Q priority of the Layer 2 message. This has the problem of low efficiency in communication between users.

[0032] The embodiments of the present application solve the problem of low efficiency of communication between users in the prior art by providing a user-based traffic diversion method and device. The communication user site path provided by the operator server is obtained by the sending communication user headquarters, the communication user mapping relationship is recorded, the sending communication user message transmitted by the communication user site path is received and the corresponding sending communication user and receiving communication user are determined. The sending communication user message is encapsulated and forwarded to the remote node according to the communication user mapping relationship, and the remote node forwards it to the receiving communication user headquarters. The receiving communication user headquarters then receives and processes the sending communication user message and sends it to the receiving communication user, thereby improving the efficiency of communication between users.

[0033] The technical solution in the embodiments of the present application is to solve the problem of low communication efficiency between users. The overall idea is as follows:

[0034] By sending the sending end communication user message to the sending end communication user headquarters via the communication user site path, the sending end communication user headquarters encapsulates the sending end communication user message according to the recorded communication user mapping relationship and forwards it to the receiving end communication user headquarters. The receiving end communication user headquarters receives and processes it and then sends it to the receiving end communication user, thereby achieving the effect of improving the communication efficiency between users.

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] As shown in Figure 1, a flow chart of a user-based traffic diversion method provided in an embodiment of the present application is provided. The method is applied to a user-based traffic diversion device, and the method includes the following steps: S1, communication user site path acquisition: the sending communication user headquarters obtains the communication user site path provided by the operator server; S2, communication user mapping relationship record: the sending communication user headquarters records the communication user, IPv6 segment routing traffic engineering policy and service sharing information model table entries; S3, message reception judgment: the sending communication user headquarters receives the sending communication user message transmitted by the communication user site path, and determines the sending communication user and the receiving communication user of the sending communication user message; S4, message encapsulation and transmission: the sending communication user headquarters encapsulates the sending communication user message according to the communication user, IPv6 segment routing traffic engineering policy and service sharing information model table entries, and then forwards the sending communication user message to the remote node, which is forwarded to the receiving communication user headquarters, and then the receiving communication user headquarters receives and processes the sending communication user message, and finally sends the sending communication user message to the receiving communication user through the communication user site path.

[0037] In this embodiment, the IPv6 segment routing traffic engineering strategy optimizes routing paths and traffic distribution according to the specific needs and priorities of the network, and preferentially routes important and sensitive traffic to more reliable and high-performance paths, thereby avoiding network congestion caused by overloading of certain paths and improving the efficiency of communication between users.

[0038] Furthermore, as shown in Figure 2, which is a communication user network structure diagram provided in an embodiment of the present application, the communication user site path in S1 is the path of the IPv6 segment routing traffic engineering strategy that meets the service level agreement, and is composed of two parts: the sending end communication user site path and the receiving end communication user site path. The communication user site path between communication users is a prerequisite for message transmission.

[0039] In this embodiment, the communication user site path is provided by the operator; the Service Level Agreement (SLA) refers to an agreement signed between the communication user and the operator, which stipulates the service level and quality standards that the service provider should provide, such as service availability, fault response time, service quality, etc., to reduce possible risks and uncertainties; the end-to-end service level agreement is achieved through the characteristics of the IPv6 segment routing traffic engineering strategy, thereby ensuring the reliability, bandwidth, and latency of the service quality between the sending end communication user headquarters and the receiving end communication user headquarters, and achieving improved accuracy and reliability of message sending and message receiving between communication users.

[0040] Furthermore, as shown in FIG3 , which is a sample diagram of table entries of communication users, IPv6 segment routing traffic engineering policies and service sharing information models provided in an embodiment of the present application, the table entries of communication users, IPv6 segment routing traffic engineering policies and service sharing information models in S2 are implemented by manual configuration, and the manual configuration methods are divided into two types: manual configuration in a controller-free scenario and manual configuration in a controller-based scenario, specifically as follows: The process of manual configuration in a controller-free scenario is: the sending end communication user device manually and statically configures the mapping relationship between the communication user, IPv6 segment routing traffic engineering policies and service sharing information models on the sending end broadband access server, through the communication user, The mapping relationship between the IPv6 segment routing traffic engineering policy and the service sharing information model guides the sending end communication user message to the receiving end communication user headquarters and the receiving end communication user. The table entries of the communication user, IPv6 segment routing traffic engineering policy and service sharing information model include the communication user's address, the communication user's IPv6 segment routing traffic engineering policy and the communication user's service sharing information model; the process of manual configuration in the controller scenario is called: the service sharing information model is sent to the controller through BGP-LS, and the controller sends the mapping relationship between the communication user, IPv6 segment routing traffic engineering policy and service sharing information model to the sending end broadband access server through the network configuration protocol.

[0041] In this embodiment, the Broadband Access Server (BAS) is a router; the service sharing information model is sent to the controller via BGP-LS. Specifically, the topology information discovered by the IGP protocol is summarized by the BGP protocol and then sent to the upper-layer controller, which reduces the computing power requirements of the upper-layer controller and is beneficial to path selection and calculation. The efficiency of topology collection of the service sharing information model is improved.

[0042] Furthermore, the service sharing information model is a sharing information model statically configured by the broadband access server at the sending end, and the service sharing information model includes a mapping relationship between the communication user site at the sending end and the sharing information model.

[0043] In this embodiment, the Shared Information Data / Model (SID) enables multiple communication users to access and share the same information simultaneously. Communication users can obtain the latest information in real time, thereby improving the efficiency of information access and sharing. It enables multiple communication users to collaborate and communicate simultaneously, and can eliminate repeated data collection and processing processes, thereby improving work efficiency and accuracy.

[0044] Furthermore, as shown in Figure 4, a message reception judgment flow chart is provided for an embodiment of the present application. The message reception judgment in S3 has the following specific process: the sending end communication user headquarters performs authentication on the sending end broadband access server; the sending end communication user headquarters receives the sending end communication user message; the sending end communication user headquarters checks the communication user information of the sending end communication user message; the sending end communication user headquarters determines the sending end communication user and the receiving end communication user of the sending end communication user message based on the communication user information.

[0045] In this embodiment, the communication user information of the sender communication user message includes information of the sender communication user and the receiver communication user of the sender communication user message, thereby improving the accuracy of message transmission between the sender communication user and the receiver communication user.

[0046] Furthermore, the communication user information will vary depending on the layer number of the communication user message at the sending end, as follows: when the communication user message at the sending end is a layer 2 message, the communication user information includes the corresponding MAC and VLAN content; when the communication user message at the sending end is a layer 3 message, the communication user information includes a layer 3 IP.

[0047] In this embodiment, the sending end communication user headquarters can determine the sending end communication user message through the communication user information without adopting different methods according to the number of layers of the sending end communication user message, thereby improving the sending and receiving efficiency of the sending end communication user message and improving the versatility of the user-based diversion method.

[0048] Furthermore, the specific process of encapsulation and forwarding in S4 is as follows: the sending end communication user headquarters encapsulates the sending end communication user message based on the communication user, IPv6 segment routing traffic engineering strategy and service sharing information model table, forms the IPv6 header and SRH header, and then forwards the sending end communication user message.

[0049] In this embodiment, the Segment Routing Header (SRH) is an extension of the IPv6 message. The Segment Routing Header specifies an SRv6 path SRH by carrying specific information, thereby enabling more accurate determination of the sending user and the receiving user of the sending user message.

[0050] Furthermore, the SRH header includes a mapping relationship between the communication user, the IPv6 segment routing traffic engineering policy, and the service sharing information model, and the receiving end communication user information is the address of the receiving end communication user.

[0051] In this embodiment, the SRH header information uniquely identifies the sending end communication user site, and the receiving end communication user information uniquely identifies the receiving end communication user, thereby achieving more accurate determination of the sending end communication user and the receiving end communication user of the sending end communication user message.

[0052] Furthermore, in S4, the receiving-end communication user headquarters receives and processes the sending-end communication user message. The specific process is as follows: the sending-end communication user message is received by the receiving-end communication user headquarters and authenticated on the receiving-end broadband access server; then the receiving-end communication user headquarters separates the SRH header of the sending-end communication user message according to the service sharing information model to obtain the communication user information.

[0053] In this embodiment, the communication user information obtained by the receiving communication user headquarters can uniquely determine the receiving communication user of the sending communication user message, thereby improving the transmission accuracy of the sending communication user message.
