Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method, apparatus, electronic device, and network node for ensuring network transmission. Background Technology

[0002] To provide users with a better Quality of Experience (QoE), networks need to offer fine-grained, even application-level, Service-Level Agreements (SLAs). Centralized solutions based on Software Defined Networking (SDN) rely on orchestrators to perceive application needs and orchestrate paths. However, long decision paths are unsuitable for applications with high timeliness requirements, and the interaction between numerous interfaces across systems is difficult. Figure 1 As shown. Furthermore, traditional network messages cannot carry sufficient information to indicate the diverse SLA requirements of various applications or services.

[0003] Therefore, the industry has proposed an Access Point Name (APN) architecture, such as... Figure 2 As shown, the message structure of APN is as follows: Figure 3 As shown.

[0004] In the APN mechanism, for example in the Headend node, it is possible to parse this accompanying APN information and provide services on demand.

[0005] The APN scheme requires defining entirely new message headers, resulting in significant changes; moreover, the requirements of applications (or services), users, and network demands are carried in each packet, leading to high overhead; furthermore, it does not consider computational information and cannot perform computation-network collaborative optimization; finally, the standardization progress of APN is slow due to security issues.

[0172] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, phrases such as "in one embodiment," "in one embodiment," or "in an alternative embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0173] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0174] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0175] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0176] To address the issues of high overhead and poor security in existing APN schemes, embodiments of the present invention provide a network transmission protection method, apparatus, electronic device, and network node.

[0177] like Figure 4 As shown, this embodiment of the invention provides a network transmission protection method applied to a first device, the method comprising:

[0178] Step 401: Send a request message to the second device, the request message being used to instruct the network node between the first device and the second device to perform a semantic action of a first target type; the first target type is a fine-grained type or an application-level service level agreement (SLA) guarantee type.

[0179] It should be noted that the number of network nodes between the first device and the second device is one, two or more, and is not limited in this embodiment of the invention.

[0180] In this embodiment of the invention, the first device is taken as a proxy device (client) and the second device is a centralized control device (centralized controller) for the following description.

[0181] In this step, the first device sends a request to the second device. The request type is a request for semantic actions with fine-grained or even application-level SLA guarantees from nodes along the route (network nodes).

[0182] Step 402: Send a target packet to the network node, the target packet carrying an address index;

[0183] Wherein, the address index is used to instruct the network node to look up the target semantic table according to the address index; the target semantic table is used to instruct the network node to perform the semantic action indicated by the target message; the target semantic table is sent by the second device to the target network node according to the request information.

[0184] In this step, after receiving the request information, the second device sends the target semantic table to each network node. The first device sends a service message (i.e., a target message) carrying an address index to each network node. After each network node receives the target message, it looks up the target semantic table according to the address index and executes the semantic action indicated by the target message according to the target semantic table.

[0185] As an optional embodiment of the present invention, before sending the target message to the network node, the method further includes:

[0186] The target message is determined based on the address index and the first information of the first update frequency, wherein the first update frequency is a high change update frequency, that is, in this embodiment, the target message carries the address index and the first information of the high change update frequency.

[0187] The address index includes at least one of the following:

[0188] User address index; Business address index; Application address index;

[0189] The first information includes at least one of the following:

[0190] Network information; computing information; energy consumption information.

[0191] In one embodiment of the present invention, the message format of the target message is defined as follows: the target message includes an address index and at least one of the following:

[0192] The second target type indicates the second information that the index target corresponding to the address index needs to protect;

[0193] Indicates the length of the Value required to represent the second information of the second target type;

[0194] Indicates the Value that represents the second type of information of the second target.

[0195] The address index includes at least one of the following:

[0196] User address index; Business address index; Application address index;

[0197] The indexing target includes at least one of the following:

[0198] Business; Application; User;

[0202] Differentiated Services Code Point (DSCP) priority type;

[0203] Queue priority type;

[0204] Queue buffer depth priority type;

[0205] Process priority type.

[0206] For example, in this embodiment, such as Figure 5 As shown, the target message uses the TLV (Type, Length, Value) format for easy and flexible expansion.

[0207] Figure 5 In this context, ADDR represents the address index: 4 bytes, used to retrieve the target semantic table of a network node and find the information of the index target (service, application, user) that the TLV needs to act on;

[0208] Type indicates the second target type: 2 bytes, indicating the type of the second information (service information, resource information) that the corresponding index target of ADDR needs to guarantee, such as DSCP type, queue priority type, queue buffer (Buffer) depth type, process priority type, etc.;

[0209] Length indicates the length of the Value: 2 bytes, indicating the length of the Value required to represent the second information of the second target type, with the length unit being bytes;

[0210] Value represents the value: Length bytes, indicating the specific value of the second information representing the second target type.

[0211] In an optional embodiment of the present invention, sending the target message to the network node includes:

[0212] The target message is sent to the network node through the target protocol data plane; that is, the target message can be carried on the target protocol data plane.

[0213] The target protocol data plane is one of the following:

[0214] Multiprotocol Label Switching (MPLS); Internet Protocol version 4 (IPv4); Internet Protocol version 6 (IPv6); Segmentation Routing Protocol version 6 (SRv6).

[0215] In this embodiment of the invention, the SRv6 protocol extension is used as an example for description:

[0216] like Figure 6 As shown, the Segment Routing Header (SRH) extension header supports multiple segment identifiers (SIDs), each SID being 128 bits long and containing three parts: Locator, Function, and Argument. The bit width of each part can be flexibly defined, such as... Figure 7 As shown, it has excellent programmability.

[0217] The target message ADDR provided in this embodiment of the invention occupies the Function and Argument part of one SID, totaling 32 bits, with the remaining 96 bits used for the Locator. The target message TLV is carried through the Optional TLV variable field in the SRH extension header, as shown in Table 1 below.

[0219]

[0220] like Figure 8 As shown, this embodiment of the invention provides a network transmission protection method applied to a second device, the method comprising:

[0221] Step 801: Receive request information sent by the first device, the request information being used to instruct the network node between the first device and the second device to perform a semantic action of a first target type; the first target type is a fine-grained type or an application-level service level agreement (SLA) guarantee type.

[0226] In this step, after receiving the request information, the second device sends the target semantic table to each network node. The first device sends a service message (i.e., a target message) carrying an address index to each network node. After each network node receives the target message, it looks up the target semantic table according to the address index and executes the semantic action indicated by the target message according to the target semantic table.

[0236] The optional fields include at least one of the following:

[0237] The bandwidth to be guaranteed; the maximum tolerable latency; the maximum tolerable jitter; and the minimum computing resources required.

[0238] The target semantic table also includes an extensible part.

[0239] For example, an embodiment of the target semantic table provided by the present invention is shown in Table 2 below:

[0240] Table 2 Target Semantic Table

[0241]

[0242] Among them, ADDR, APP-Group-ID and USER-Group-ID are required fields of the target semantic table, while Bandwidth, Delay, Jitter and Computing Capacity are optional fields (opt). The target semantic table can also be expanded with more fields as needed.

[0243] In an optional embodiment of the present invention, the target semantic table can be distributed and configured in a centralized, distributed, or hybrid manner, or it can be configured manually.

[0244] In this embodiment, sending the target semantic table to the network node includes at least one of the following:

[0245] The target semantic table is sent to the network node via the southbound interface of the central controller;

[0246] The target semantic table is sent to the network node via a distributed routing protocol;

[0247] Based on the relationship between the network domains of the first device and the second device, the target semantic table is sent to the network node in a targeted manner. The targeted manner can be through the southbound interface of the centralized controller or through a distributed routing protocol. Specifically, if the network domains of the first device and the second device are the same, the target semantic table is sent to the network node through the southbound interface of the centralized controller; if the network domains of the first device and the second device are different, the target semantic table is sent to the network node through a distributed routing protocol.

[0248] The details are as follows, centralized:

[0249] Semantic actions that require fine-grained or even application-level SLA guarantees from nodes along the route (network nodes) are distributed to each node along the route through the southbound interface of the centralized controller (such as a Software Defined Network (SDN) controller).

[0250] distributed:

[0251] Semantic actions requiring fine-grained or even application-level SLA guarantees from nodes along the route (network nodes) are advertised to each node along the route through distributed routing protocols (such as Open Shortest Path First (OSPF) routing protocol, Border Gateway Protocol (BGP) etc.).

[0252] Hybrid:

[0253] Semantic actions requiring fine-grained or even application-level SLA guarantees from nodes (network nodes) along the route are centrally distributed within the domain and announced through distributed distribution between domains.

[0254] It should also be noted that the method by which network nodes obtain the content of the target semantic table is not limited in the embodiments of the present invention. It can be that the user, application or service actively announces to each network node in the network through the northbound interface of the controller or orchestrator or through the distributed routing protocol. Alternatively, it can be that the network edge node passively senses and announces to each network node in the network through methods such as Deep Packet Inspection (DPI).

[0255] like Figure 9 As shown, this embodiment of the invention provides a network transmission guarantee method applied to a network node, the method comprising:

[0256] Step 901: Receive the target semantic table sent by the second device according to the request information; the request information is sent by the first device to the second device; the request information is used to indicate that the network node between the first device and the second device needs to perform a semantic action of a first target type; the first target type is a fine-grained type or an application-level service level agreement (SLA) guarantee type.

[0257] It should be noted that the number of network nodes between the first device and the second device is one, two, or more network nodes, and is not limited in this embodiment of the invention.

[0258] In this embodiment of the invention, the network node is any network node between the first device and the second device.

[0259] In this embodiment of the invention, the first device is taken as a proxy device (client) and the second device is a centralized control device (centralized controller) for the following description.

[0260] In this step, the first device sends a request to the second device. The request type is a request for nodes along the route (network nodes) to perform semantic actions with fine-grained or even application-level SLA guarantees. After receiving the request, the second device sends the target semantic table to each network node.

[0261] Step 902: Receive the target message sent by the first device, the target message carrying an address index.

[0262] In this step, the first device sends a service message (i.e., a target message) carrying an address index to each network node, and the network nodes receive the target message sent by the first device.

[0263] Step 903: Look up the target semantic table according to the address index, and execute the semantic action indicated by the target message according to the target semantic table.

[0264] In this step, after the network node receives the target message and target semantic table, it looks up the target semantic table according to the address index and executes the semantic action indicated by the target message according to the target semantic table.

[0265] In an optional embodiment of the present invention, the target message further includes at least one of the following:

[0266] The second target type indicates the second information that the index target corresponding to the address index needs to protect;

[0267] Indicates the length of the Value required to represent the second information of the second target type;

[0268] Indicates the Value that represents the second type of information of the second target.

[0269] The address index includes at least one of the following:

[0270] User address index; Business address index; Application address index;

[0271] The indexing target includes at least one of the following:

[0272] Business; Application; User;

[0273] The second information includes at least one of the following:

[0274] Service information; resource information.

[0275] In an optional embodiment of the present invention, the second target type includes at least one of the following:

[0276] Differential service code point DSCP priority type;

[0277] Queue priority type;

[0278] Queue buffer depth priority type;

[0279] Process priority type.

[0280] In an optional embodiment of the present invention, the target semantic table includes required fields and optional fields;

[0281] The required fields include at least one of the following:

[0282] Index address; application group identification information; user group identification information;

[0283] The optional fields include at least one of the following:

[0284] The bandwidth to be guaranteed; the maximum tolerable latency; the maximum tolerable jitter; and the minimum computing resources required.

[0285] The following is combined Figure 10 Taking a pair of client and server, two intermediate network nodes (node1 and node2), and a centralized controller (controller(opt)) as an example, the specific process of the network transmission guarantee method provided in this embodiment of the invention is explained in detail:

[0286] Step 1: The client sends a corresponding request to the controller. The request type is "Request to perform semantic actions with fine-grained or even application-level SLA guarantees along the way".

[0287] Step 2: The controller sends the target semantic table to each network node.

[0288] Step 3: The client sends service messages (target messages) with message headers to each network node.

[0289] Step 4: After each network node receives the above service message, it searches the target semantic table and executes the semantic action indicated by the TLV in the target message.

[0290] The network transmission assurance method provided in this invention proposes a solution where the target packet carries an address index and information with high update frequency, or only carries address index information, while the specific semantics of information with low update frequency are maintained at the forwarding node (network node). The target packet, as it passes through network nodes along the route, executes the corresponding strategy by "looking up the target semantic table" based on the index address. This approach provides fine-grained or even application-level SLA assurance and overcomes the overhead and security issues associated with solutions like APN.

[0291] The network transmission assurance method provided in this invention can provide fine-grained or even application-level SLA assurance with low overhead based on existing protocols. It adopts the standard TLV method to flexibly carry the guarantee requirements of services or users for network, computing or energy consumption resources, and provides a general way for joint optimization of resources and energy consumption. It does not directly carry application information, service information or user information, and solves the security and privacy issues encountered in the standardization process of IETF APN scheme.

[0292] With the popularization of SRv6 and programmable networks, networks will become more flexible. This invention can be implemented with only minor modifications, thereby significantly improving network transmission efficiency, opening up more computing and network capabilities to services or applications, and enhancing network value. The market potential of cloud-network convergence and computing-network convergence is huge, and this invention has a large market space to expand and has the potential for IETF standardization.
