Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a traffic transmission method, apparatus, computer equipment and storage medium. Background Art

[0002] The operator network is usually composed of multiple regional networks (for example, metropolitan area network, DC (Internet Data Center) network and backbone network, etc.), each of which can be regarded as a network domain. Interconnection between different regional networks is achieved through inter-domain network technology.

[0003] In the existing operator network, the metropolitan area network, IDC (Internet Data Center) network and backbone network are generally connected using the inter-domain network of the EBGP (External Border Gateway Protocol) protocol. The cross-metropolitan area network services are generally forwarded using the Native IP method. For reliability considerations, two or more egress router devices are generally deployed at the metropolitan area network egress or IDC network egress. When the metropolitan area network egress and the IDC network egress are interconnected with the backbone network, the link SLA (Service Level Agreement) quality between different nodes (i.e. router devices) is different.

[0004] Due to the lack of existing methods for link service quality monitoring and link optimization, when the service quality of the export link of a node deteriorates, due to the lack of an effective link quality monitoring method, the degradation of the link service quality cannot be identified in time, and even if the degradation of the link service quality is found, the link service quality cannot be optimized in time, resulting in the inability to guarantee the existing inter-domain network communication quality and business experience.

[0065] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0066] The flow transmission method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. After receiving the traffic to be transmitted, the current routing node determines the current transmission path and traffic type of the traffic to be transmitted. Determine the first path quality information of the current transmission path. Based on the traffic type and the first path quality information, determine the first path feasibility of the current transmission path. Determine the target transmission path based on the first path feasibility and the current transmission path. Transmit the traffic to be transmitted based on the target transmission path.

[0067] For example, if the metropolitan area network needs to transmit the traffic to be transmitted to the backbone network, the current routing node is the CR1 or CR2 node in the metropolitan area network. The CR1 and CR2 nodes are routing devices in the metropolitan area network. The C5 and C6 nodes are routing devices in the backbone network. Figure 1 There are two paths between the metropolitan area network and the backbone network that can be used to transmit traffic, namely the transmission path L1 between the CR1 and C5 nodes, and the transmission path L2 between the CR2 and C6 nodes.

[0068] In one embodiment, Figure 2 is a flow chart of a flow transmission method provided according to an embodiment of the present application, in which the method is applied to Figure 1 Taking the current routing node in as an example, the method includes the following steps:

[0069] S201, after receiving the traffic to be transmitted, determine the current transmission path and traffic type of the traffic to be transmitted.

[0070] The traffic to be transmitted refers to the traffic that needs to be transmitted, which is a continuous traffic. The current transmission path refers to the transmission path with the highest priority when the current routing node transmits the traffic to be transmitted, and also refers to the transmission path that transmits the traffic to be transmitted to the next hop node. The traffic type refers to the traffic attribute type of the traffic to be transmitted, such as game business traffic, cloud computer business traffic, video business traffic, intelligent computing business traffic, etc.

[0071] In this embodiment, after receiving the traffic to be transmitted, an optional implementation method for determining the current transmission path of the traffic to be transmitted is to determine the current transmission path of the traffic to be transmitted according to the traffic characteristics of the traffic to be transmitted. The traffic characteristics include but are not limited to at least one of the protocol type, port, source address, destination address, packet length, etc. Exemplarily, after receiving the traffic to be transmitted, the current routing node determines the routing table according to the destination address of the traffic to be transmitted. Based on the routing table, the current transmission path for transmitting the traffic to be transmitted is searched.

[0072] In this embodiment, an optional implementation method for determining the traffic type of the traffic to be transmitted is to parse the traffic characteristics carried by the traffic to be transmitted and obtain the traffic type of the traffic to be transmitted from the traffic characteristics. The traffic characteristics record the traffic type or an identifier corresponding to the traffic type.

[0073] Another optional implementation method for determining the traffic type of the traffic to be transmitted in this embodiment is to pre-configure an intelligent analysis model in the current routing node, and use the intelligent analysis model to intelligently identify the traffic to be transmitted to determine the traffic type of the traffic to be transmitted (for example, game business traffic, cloud computer business traffic, video business traffic, intelligent computing business traffic, etc.). The intelligent analysis model can be, but is not limited to, a neural network model.

[0074] S202: Determine first path quality information of a current transmission path.

[0075] The first path quality information refers to the path quality information of the current transmission path that has not been optimized, and also refers to the SLA (Service Level Agreement) indicator of the current transmission path. The SLA indicator includes at least indicators such as delay, bit error and packet loss.

[0076] As an optional implementation of the embodiment of the present application, based on the quality monitoring device on the current transmission path, the first path quality information of the current transmission path is determined. Specifically, a quality acquisition request is sent to the quality monitoring device, so that the quality monitoring device feeds back the first path quality information of the current transmission path to the current routing node based on the quality acquisition request.

[0077] As another optional implementation of the embodiment of the present application, the first path quality information of the current transmission path is determined according to the signal interaction information between different routing nodes in the current transmission path. Figure 1 L1 is the current transmission path, CR1 node is the current routing node, and the first path quality information of the current transmission path can be determined through the signal interaction information between CR1 and C5 nodes. Preferably, the first path quality information of the current transmission path can be determined based on the current routing node based on the Twamp (Two-Way Active Measurement Protocol, a network performance monitoring protocol) protocol or the BFD (Bidirectional Forwarding Detection, a protocol for quickly detecting and reporting network link or path failures) protocol.

[0078] S203: Determine the first path feasibility of the current transmission path based on the traffic type and the first path quality information.

[0079] Optionally, in this embodiment, the quality requirement of the traffic type for the transmission path is determined according to the traffic type. Whether the quality requirement is met is determined according to the first path quality information, and the first path feasibility of the current transmission path is determined according to the satisfaction. If the quality requirement can be met, the first path feasibility of the current transmission path is that the current transmission path is feasible. If the quality requirement cannot be met, the first path feasibility of the current transmission path is that the current transmission path is not feasible.

[0080] S204: Determine a target transmission path according to the feasibility of the first path and the current transmission path.

[0081] The target transmission path refers to the transmission path ultimately used to transmit the traffic to be transmitted.

[0082] As an optional implementation of the embodiment of the present application, when the feasibility of the first path is feasible, the current transmission path is used as the target transmission path.

[0083] As another optional implementation of the embodiment of the present application, when the feasibility of the first path is not feasible, the target transmission path is selected from other transmission paths. Among them, other transmission paths refer to transmission paths other than the current transmission path and can transmit the to-be-transmitted traffic to the destination address.

[0084] S205: Transmit the traffic to be transmitted based on the target transmission path.

[0085] As an optional implementation of the embodiment of the present application, when the target transmission path is the current transmission path, the current routing node can directly send the traffic to be transmitted to the current transmission path through the node exit to achieve the transmission of the traffic to be transmitted.

[0086] As another optional implementation method of the embodiment of the present application, when the target transmission path is not the current routing node, one method is: the current routing node is used as the main calling device to generate a BGP RPD route and publish the BGPRPD route. After the BGP RPD route takes effect, the priority of the prefix BGP RPD route of the current routing node is reduced, so as to achieve the transfer of the traffic to be transmitted to the target transmission path, and transmit the traffic to be transmitted based on the target transmission path. Another method is: the current routing node and the opposite routing node jointly publish the BGP RPD route, and the route is effective at the same time on the current routing node and the opposite routing node. After the BGP RPD route takes effect, the priority of the BGP RPD route of the corresponding prefix is ​​reduced, and the remote traffic is diverted based on the BGP RPD route, so as to achieve the transfer of the traffic to be transmitted to the target transmission path, and transmit the traffic to be transmitted based on the target transmission path. For example, assuming Figure 1The CR1 node is the current routing node, L1 is the current transmission path, L2 is the target transmission path, and the C5 node is the destination node. When the feasibility of the first path of L1 is that the current transmission path is not feasible, the CR1 node publishes the BGP RPD route. After the BGP RPD route publication takes effect, when the traffic to be transmitted is subsequently transmitted, the CR1 node forwards the traffic to be transmitted to the CR2 node, and then transmits it to the C6 node through L2. Finally, the C6 node transmits the traffic to be transmitted to the C5 node. This embodiment can flexibly select the corresponding transmission path for different types of traffic, effectively improve the communication service instructions, and greatly improve user satisfaction.

[0087] The above-mentioned traffic transmission method determines the current transmission path and traffic type of the traffic to be transmitted after receiving the traffic to be transmitted. Determine the first path quality information of the current transmission path. Based on the traffic type and the first path quality information, determine the first path feasibility of the current transmission path. According to the first path feasibility and the current transmission path, determine the target transmission path. Transmit the traffic to be transmitted based on the target transmission path. After receiving the traffic to be transmitted, the current routing node of the present application can not only determine the first path quality information of the current transmission path of the traffic to be transmitted, but also determine the first path feasibility of the current transmission path based on the traffic type and the first path quality information of the traffic to be transmitted, and then determine the target transmission path based on the first path feasibility and the current transmission path. Transmit the traffic to be transmitted based on the target transmission path. The present application can not only determine the path quality information, but also determine the path feasibility in combination with the traffic type. While realizing path quality monitoring, it also effectively guarantees the quality of communication services and improves user experience. When determining the feasibility of the first path, the present application also takes the traffic type into consideration. Since the selection of the target transmission path needs to consider the feasibility of the first path, it can be seen that when determining the target transmission path, it is necessary to focus on the traffic type. Based on different traffic types, different transmission paths that meet the requirements of the traffic type can be flexibly selected, thereby further improving the communication service quality and user satisfaction.

[0088] In one embodiment, in order to improve the accuracy of determining the feasibility of the first path, such as Figure 3 As shown, an optional implementation method of determining the feasibility of the first path of the current transmission path based on the traffic type and the first path quality information in S203 includes:

[0089] S301, determining sensitive indicators of the traffic to be transmitted based on the traffic type.

[0090] The sensitive indicator refers to a key indicator in the traffic to be transmitted that affects the user experience, and includes but is not limited to at least one of a delay indicator, a bit error indicator, and a packet loss indicator.

[0091] Optionally, in this embodiment, based on the traffic type and traffic list, the sensitive indicator of the traffic to be transmitted is determined. The traffic list records each traffic type and the sensitive indicator corresponding to each traffic type. For example, if the traffic type is game business traffic, the sensitive indicator is the delay indicator; if the traffic type is cloud computer business traffic, the sensitive indicator is the delay jitter indicator; if the traffic type is intelligent computing business traffic, the sensitive indicator type is the packet loss indicator.

[0092] S302: Determine the first path feasibility of the current transmission path according to the sensitive indicator and the first path quality information.

[0093] Optionally, in this embodiment, an indicator value corresponding to the sensitive indicator is obtained from the first path quality information. Based on the magnitude relationship between the indicator value and the numerical threshold, the first path feasibility of the current transmission path is determined. Exemplarily, for example, if the sensitive indicator is a delay indicator, and the indicator value of the delay indicator is greater than the numerical threshold, the first path feasibility of the previous transmission path is determined to be infeasible for the current transmission path.

[0094] In this embodiment, based on the traffic type, the sensitive indicator of the traffic to be transmitted is determined. From the first path quality information, the indicator value corresponding to the sensitive indicator is obtained. Based on the relationship between the indicator value and the numerical threshold, the first path feasibility of the current transmission path is determined. In this embodiment, when determining the feasibility of the first path, the sensitive indicator of the traffic to be transmitted is taken into account, and the first path feasibility of the current transmission path is determined based on the relationship between the indicator value and the numerical threshold, so that the feasibility of the first path finally determined is strongly correlated with the sensitive indicator of the traffic to be transmitted, thereby strengthening the correlation between the feasibility of the first path and the user experience.

[0095] In one embodiment, in order to more accurately determine the target transmission path, such as Figure 4 As shown, an optional implementation manner of determining a target transmission path according to the feasibility of the first path and the current transmission path includes:

[0096] S401, when the first path feasibility indicates that the current transmission path is feasible, taking the current transmission path as the target transmission path.

[0097] S402, when the feasibility of the first path indicates that the current transmission path is not feasible, optimizing the traffic management of the current routing node to optimize the current transmission path, and determining the target transmission path according to the optimized current transmission path.

[0098] In this embodiment, the flow management of the current routing node is optimized to achieve the optional implementation of optimizing the current transmission path. The flow management of the current routing node can be optimized based on the BGP Flowspec protocol to achieve the optimization of the current transmission path.

[0099] Optionally, in this embodiment, according to the optimized current transmission path, an optional implementation method for determining the target transmission path is to determine the second path quality information of the optimized current transmission path. Based on the traffic type and the second path quality information, the feasibility of the second path of the optimized current transmission path is determined. According to the feasibility of the second path and the optimized current transmission path, the target transmission path is determined. For the specific implementation method, reference can be made to the method for determining the first path quality information and the feasibility of the second path in the above embodiment, which will not be repeated here.

[0100] On the basis of the above embodiment, an optional implementation method for determining the target transmission path according to the feasibility of the second path and the optimized current transmission path is to use the optimized current transmission path as the target transmission path when the feasibility of the second path is feasible for the optimized current transmission path.

[0101] On the basis of the above embodiments, an optional implementation method for determining the target transmission path according to the feasibility of the second path and the optimized current transmission path is to obtain the third path quality information of the candidate transmission path when the feasibility of the second path is not feasible for the optimized current transmission path. The third path quality information is sent to the current routing node by other routing nodes; other routing nodes are routing nodes other than the current routing node in the regional network. The target transmission path is selected from the candidate transmission paths according to the indicator value corresponding to the sensitive indicator of the traffic to be transmitted in the third path quality information. Optionally, in this embodiment, the current routing node can receive a Border Gateway Protocol BGP-LS protocol message sent by other routing nodes; wherein the BGP-LS protocol message carries the third path quality information. That is to say, routing nodes of different transmission paths can transmit corresponding path quality information to each other through BGP-LS protocol messages. Exemplarily, with Figure 1 For example, the CR2 node and the CR1 node can exchange information in the form of BGP-LS protocol messages and transmit L1 and L2 path quality information to each other.

[0102] In this embodiment, an optional implementation method of selecting a target transmission path from candidate transmission paths based on the indicator value corresponding to the sensitive indicator of the traffic to be transmitted in the third path quality information is as follows: if there are multiple candidate transmission paths, first determine whether there is a candidate transmission path among the candidate transmission paths whose indicator value of the sensitive indicator is higher than the indicator value of the sensitive indicator of the optimized current transmission path; if so, select the candidate transmission path with the largest indicator value of the sensitive indicator as the target transmission path.

[0103] In this embodiment, when the feasibility of the first path is that the current transmission path is feasible, the current transmission path is used as the target transmission path. When the feasibility of the first path is that the current transmission path is not feasible, the traffic management of the current routing node is optimized to optimize the current transmission path, and determine the second path quality information of the optimized current transmission path. Based on the traffic type and the second path quality information, the feasibility of the second path of the optimized current transmission path is determined. When the feasibility of the second path is that the optimized current transmission path is not feasible, the third path quality information of the candidate transmission path is obtained; wherein the third path quality information is sent to the current routing node by other routing nodes; other routing nodes are routing nodes other than the current routing node in the regional network. According to the indicator value corresponding to the sensitive indicator of the traffic to be transmitted in the third path quality information, the target transmission path is selected from the candidate transmission paths. Based on this embodiment, a target transmission path that meets the requirements more accurately can be selected.

[0104] In one embodiment, if Figure 5 As shown, another optional implementation of a traffic transmission method includes:

[0105] S501, after receiving the traffic to be transmitted, determine the current transmission path and traffic type of the traffic to be transmitted.

[0106] S502: Determine first path quality information of the current transmission path according to signal interaction information between different routing nodes in the current transmission path.

[0109] S505: Determine the feasibility of a first path of the current transmission path based on a relationship between the indicator value and the numerical threshold.

[0112] S508: Determine the second path quality information of the optimized current transmission path.

[0113] S509: Determine the feasibility of the second path of the optimized current transmission path based on the traffic type and the second path quality information.

[0114] S510, when the second path feasibility is that the optimized current transmission path is not feasible, obtain third path quality information of the candidate transmission path. The third path quality information is sent to the current routing node by other routing nodes; the other routing nodes are routing nodes other than the current routing node in the regional network.

[0115] S511, select a target transmission path from candidate transmission paths according to the indicator value corresponding to the sensitive indicator of the to-be-transmitted traffic in the third path quality information. The third path quality information is recorded in a BGP-LS protocol message; the BGP-LS protocol message is sent by other routing nodes to the current routing node.

[0116] S512, transmitting the traffic to be transmitted based on the target transmission path.

[0117] In this embodiment, after receiving the traffic to be transmitted, the current transmission path and traffic type of the traffic to be transmitted are determined. The first path quality information of the current transmission path is determined. Based on the traffic type and the first path quality information, the first path feasibility of the current transmission path is determined. According to the first path feasibility and the current transmission path, the target transmission path is determined. The traffic to be transmitted is transmitted based on the target transmission path. After receiving the traffic to be transmitted, the current routing node of the present application can not only determine the first path quality information of the current transmission path of the traffic to be transmitted, but also determine the first path feasibility of the current transmission path based on the traffic type and the first path quality information of the traffic to be transmitted, and then determine the target transmission path based on the first path feasibility and the current transmission path. The traffic to be transmitted is transmitted based on the target transmission path. The present application can not only determine the path quality information, but also determine the path feasibility in combination with the traffic type. While realizing path quality monitoring, it also effectively guarantees the quality of communication services and improves user experience.
