[0094] In order to better meet the service needs, in the related art, the forwarding path of the service data is calculated according to the network requirements of the service such as bandwidth and delay, and then the corresponding network resources are reserved on the forwarding path based on RSVP, for example, bandwidth resources are reserved. When the reserved network resources need to be released, the path removal message corresponding to the forwarding path needs to be sent first, and then the network resources can be released. Therefore, the end time of the reservation cannot be clearly defined, and therefore the start and end time of the reservation cannot be clearly defined when reserving network resources. In order to better meet the service quality (QoS, Quality of Service) requirements of the service, the research results of deterministic network research provide a network resource reservation mechanism, which can specify the start time and duration of network resource reservation, and can realize accurate reservation of network resources. However, the processing process of the service includes two parts: path transmission and node calculation, which correspond to the occupation of network resources and computing resources respectively. In the related art, it is still impossible to clarify the reservation start and end time of computing resources, resulting in the inability to coordinate network resources and computing resources to achieve resource reservation, and the inability to effectively guarantee service needs.

[0095] Based on this, the embodiments of the present application provide a network resource reservation method, device, network node, computing node and storage medium, wherein a first network node sends a first signaling to a first computing node, wherein the first signaling is at least used to request to reserve a first computing resource for a first data stream; the first signaling carries a first time parameter and a second time parameter; the first time parameter represents the reservation start time of the first computing resource; the second time parameter represents the reservation end time of the first computing resource. The first computing node reserves the first computing resource for the first data stream based on the first time parameter and the second time parameter, so that the business data can have sufficient computing power guarantee on the computing node, thereby further guaranteeing the business needs on the basis of network resource reservation.

[0096] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0097] The embodiment of the present application provides a resource reservation method, which is applied to a first network node. Here, the first network node may be a network control node (Controller), such as Figure 1 As shown, the method includes:

[0098] Step 101: Send a first signaling to a first computing node.

[0099] Among them, the first signaling is at least used to request to reserve a first computing resource for a first data stream; the first signaling carries a first time parameter and a second time parameter; the first time parameter represents the reservation start time of the first computing resource; the second time parameter represents the reservation end time of the first computing resource.

[0100] In actual application, before executing step 101, the terminal first initiates a service request to the first network node, and the service request carries the corresponding service demand. The first network node reserves resources for the corresponding service data flow based on the corresponding service demand. In the related art, resource reservation is a resource reservation for network resources, including indicating the network resource reservation amount and the reservation start and end time of the network resource based on RSVP. In the embodiment of the present application, the resource reservation scheme in the related art is extended. Specifically, the first network node maps the corresponding service demand to the network resource demand and the computing resource demand, and determines the corresponding network resource reservation strategy based on the network resource demand, and determines the corresponding computing resource reservation strategy based on the computing resource demand. In other words, on the basis of the resource reservation scheme in the related art, a resource reservation strategy for computing resources is extended, including the start time of the computing resource reservation and the end time of the computing resource reservation.

[0101] Here, the first network node sends a first signaling to the first computing node, and the first signaling is at least used to request to reserve a first computing resource for a first data flow, that is, a business data flow, and the first signaling carries a corresponding computing resource reservation strategy, which is determined based on the computing resource demand mapped by the corresponding business demand. In actual application, the first signaling can be an iPath signaling, and illustratively, the iPath message carries the reservation status information cookie (i, j) of the data flow i on the computing node j, wherein the cookie (i, j) represents the computing resource reservation strategy of the data flow i on the computing node j, including the start time and end time of the computing resources required by the data flow i on the computing node j.

[0102] That is, before executing step 101, it is necessary to determine the first time parameter and the second time parameter carried in the first signaling respectively.

[0103] Based on this, in one embodiment, before sending the first signaling to the first computing node, the method further includes:

[0104] The first time parameter is determined based on at least one of the following:

[0105] a reservation expiration time of the network resources corresponding to the first data flow;

[0106] Network status;

[0107] The running status of the first computing node.

[0108] Here, the computing resource reservation start time for the first data stream on the first computing node is determined based on the network resource reservation end time corresponding to the first data stream. Typically, the reservation start time of the computing resources on the first computing node is later than the reservation end time of the corresponding network resources on the forwarding path through which the first data stream is transmitted to the first computing node. Of course, it is understandable that the time represented by the first time parameter may also be earlier than the reservation end time of the corresponding network resource, or be the same as the reservation end time of the corresponding network resource.

[0109] In actual application, when determining the first time parameter, in addition to referring to the reserved end time of the corresponding network resource, the network status and the operating status of the first node can also be combined to participate in the decision-making of multiple factors to determine the first time parameter.

[0110] Before sending the first signaling to the first computing node, the method further includes:

[0111] Based on the first information, the second time parameter is determined; wherein,

[0112] The first information represents the operating status of the first computing node.

[0113] In actual application, the first network node predicts the reserved time length for the first computing resource on the first computing node based on the running status of the first computing node, and on this basis, determines the second time parameter based on the first time parameter and the reserved time length.

[0114] In one embodiment, the method further comprises:

[0115] Receive a second signaling sent by the first computing node; the second signaling indicates that the first computing node confirms to reserve the first computing resource for the first data flow based on the first time parameter and the second time parameter.

[0116] Here, after receiving the first signaling carrying the computing resource reservation policy, the first computing node checks whether the computing node is conditionally capable of executing the corresponding computing resource reservation policy, and sends the second signaling in the reverse direction to the first network node after confirming that the first computing resource can be reserved for the first data flow based on the corresponding computing resource reservation policy. In actual application, the second signaling can be an iResv signaling, and the signaling carries the same reservation status information cookie (i, j) as that in the iPath signaling, so that after receiving the iResv signaling, the first network node can determine that computing node j confirms to execute the corresponding computing resource reservation policy based on the reservation status information cookie (i, j) carried in the iRESV signaling.

[0117] The above describes the process in which the first network node determines a computing resource reservation strategy based on the computing resource demand corresponding to the first data flow, transmits the computing resource reservation strategy to the first computing node, and the first computing node confirms the execution of the computing resource reservation strategy. It is easy to understand that in addition to formulating and issuing a computing resource reservation strategy, the first network node can also formulate and issue a network resource reservation strategy in accordance with relevant technologies. At this time, the first information is also used to indicate that network resources are reserved for the first data flow. In this way, the obtained network resource reservation strategy and computing resource reservation strategy can be represented as: (flow ID, reserved bandwidth, start time t1, end time t2): (flow ID, reserved computing resources, start time t3, end time t4), where "flow ID" represents the data flow of the first data flow, and usually, t3 is greater than or equal to t2.

[0118] After the first network node sends the resource reservation policy to the first computing node, since network resources and computing resources may be updated, the previously formulated resource reservation policy may not meet business needs after the update. Therefore, it is necessary to dynamically adjust the reservation duration of the reserved resources.

[0119] Based on this, in one embodiment, after sending the first signaling to the first computing node, the method further includes:

[0120] Send a third signaling; the third signaling is at least used to request adjustment of reserved resources corresponding to the first data flow.

[0121] Here, when the network state or the computing node state changes, the network node on the transmission path of the first data flow may initiate adjustment of the resource reservation policy. Here, the network node that may initiate adjustment of the resource reservation policy includes one of the following:

[0122] Control nodes;

[0123] Intermediate routing nodes;

[0124] Inter-domain router.

[0125] At this time, when the network node that initiates the adjustment of the resource reservation strategy is the first network node, that is, the control node, the first network node re-determines the resource reservation amount and the corresponding reservation start and end time based on the real-time network status and the operation status of the computing node. Specifically, when the real-time network delay is greater than the network delay when the network resource reservation strategy is initially formulated, it is necessary to apply for an extension of the network resource reservation, and the network resource reservation termination time is correspondingly postponed. At the same time, since the service data reaches the computing node after passing through the forwarding path, the delay of the network resource reservation termination time will also lead to the delay of the computing resource reservation termination time. In this case, both the network resource reservation termination time and the computing resource reservation termination time need to be adjusted accordingly; when the real-time computing delay is greater than the computing delay when the computing resource reservation strategy is initially formulated, it is necessary to apply for an extension of the computing resource reservation, and the computing resource reservation termination time is correspondingly postponed. In addition, when the status of the computing node changes, it may also lead to a change in the computing resource reservation amount, and the computing resource reservation amount needs to be adjusted accordingly.

[0126] Based on this, the third signaling carries at least one of the following:

[0127] A first adjustment amount; the first adjustment amount is used to adjust the resource amount of the first computing resource;

[0128] A fourth time parameter; the fourth time parameter represents the adjusted reservation expiration time of the first computing resource;

[0129] A fifth time parameter; the fifth time parameter represents the adjusted network resource reservation termination time corresponding to the first data flow.

[0130] In actual application, when the resource reservation policy is initially issued, the reserved computing resources and the corresponding reservation duration are defined by extending the Object object in RSVP-TE, so that the first computing node can accurately reserve computing resources based on the corresponding computing resource reservation policy.

[0131] Based on this, in one embodiment, the CLASS NUM in the Object header of the first signaling is represented as a first type number; the first type number represents that the first signaling is used to request to reserve computing resources; or,

[0132] The first signaling is also used to request to reserve network resources for the first data flow; the CLASS NUM in the Object header of the first signaling represents a second type number; the second type number represents that the first signaling is used to request to reserve computing resources and network resources.

[0133] Here, the first signaling is characterized by different CLASS NUMs and is used to request to reserve computing resources and / or network resources.

[0134] In actual application, CLASS NUM=31 may be defined, and in this case, the first signaling is used to request the reserved computing resources separately. As shown in Table 1, the message body example specifies the start and end time of the reserved computing resources.

[0135] Table 1

[0136]

[0137] Alternatively, CLASS NUM=30 may be defined, in which case the first signaling is used to request to reserve computing resources and network resources at the same time. As shown in Table 2, the message body example specifies the start and end time of reserving network resources and the start and end time of reserving computing resources.

[0138] Table 2

[0139]

[0140] Alternatively, CLASS NUM=30 may be defined, in which case the first signaling is used to request to reserve computing resources and network resources at the same time. As shown in Table 2, the message body example specifies the start and end time of reserving network resources and the start and end time of reserving computing resources.

[0141] Based on the extended protocol format described above, when the network state or the running state of the computing node changes, the CLASS NUM of the Object header of the third signaling is the same as the CLASS NUM of the Object header of the first signaling; or,

[0142] The CLASS NUM in the Object header of the third signaling indicates a third type number; the third type number indicates that the third signaling is used to request adjustment of reserved resources.

[0143] That is, when adjusting reserved resources, the same CLASS NUM as that used when initially sending reserved resources may be used in the signaling; or, when adjusting reserved resources, a new CLASS NUM may be specified, which is used to mark the corresponding signaling for requesting adjustment of reserved resources.

[0144] In actual application, the signaling process of resource reservation adjustment is similar to the signaling process of initial resource reservation, including two types of signaling: rPath and rResv. The difference is that in the signaling process of resource reservation adjustment, the start time of the reserved resources of the rPath signaling is after the end time of the reserved resources in the previous rPath signaling, and the sending of the rPath signaling must be completed before the end time of the reserved resources in the previous rPath signaling.

[0145] When the reserved resources need to be removed in advance, a Teardown signaling needs to be sent from the computing node. The computing node first clears the computing resource reservation status of the data flow from the computing node, and then generates the corresponding cookie information and embeds it into the Teardown signaling, notifying the network nodes along the forwarding path to eliminate the resource reservation for the data flow.

[0146] Accordingly, the embodiment of the present application also provides a resource reservation method, which is applied to the first computing node, such as Figure 2 As shown, the method includes:

[0147] Step 201: Receive a first signaling sent by a first network node.

[0148] Among them, the first signaling is at least used to request to reserve a first computing resource for a first data stream; the first signaling carries a first time parameter and a second time parameter; the first time parameter represents the reservation start time of the first computing resource; the second time parameter represents the reservation end time of the first computing resource.

[0149] In actual application, before executing step 201, the terminal first initiates a service request to the first network node, and the service request carries the corresponding service demand. The first network node reserves resources for the corresponding service data flow based on the corresponding service demand. In an embodiment of the present application, the resource reservation scheme in the related technology is expanded. Specifically, the first network node maps the corresponding service demand to network resource demand and computing resource demand, and determines the corresponding network resource reservation strategy based on the network resource demand, and determines the corresponding computing resource reservation strategy based on the computing resource demand. In other words, on the basis of the resource reservation scheme in the related technology, a resource reservation strategy for computing resources is expanded, including the start time of computing resource reservation and the end time of computing resource reservation.

[0150] Here, the first network node sends a first signaling to the first computing node, and the first signaling is at least used to request to reserve a first computing resource for a first data flow, that is, a business data flow, and the first signaling carries a corresponding computing resource reservation strategy, which is determined based on the computing resource demand mapped by the corresponding business demand. In actual application, the first signaling can be an iPath signaling, and illustratively, the iPath message carries the reservation status information cookie (i, j) of the data flow i on the computing node j, wherein the cookie (i, j) represents the computing resource reservation strategy of the data flow i on the computing node j, including the start time and end time of the computing resources required by the data flow i on the computing node j.

[0151] Step 202: Based on the first time parameter and the second time parameter, reserve the first computing resource for the first data flow.

[0152] In one embodiment, the method further comprises:

[0153] Sending a second signaling to the first network node; the second signaling indicates that the first computing node confirms reserving the first computing resource for the first data flow based on the first time parameter and the second time parameter.

[0154] Here, after receiving the first signaling carrying the computing resource reservation policy, the first computing node checks whether the computing node is conditionally capable of executing the corresponding computing resource reservation policy, and sends the second signaling in the reverse direction to the first network node after confirming that the first computing resource can be reserved for the first data flow based on the corresponding computing resource reservation policy. In actual application, the second signaling can be an iResv signaling, and the signaling carries the same reservation status information cookie (i, j) as that in the iPath signaling, so that after receiving the iResv signaling, the first network node can determine that computing node j confirms to execute the corresponding computing resource reservation policy based on the reservation status information cookie (i, j) carried in the iRESV signaling.

[0155] In the embodiment of the present application, after the first computing node confirms the execution of the corresponding computing resource reservation policy, the computing resource reservation schedule is maintained locally at the first computing node. Figure 3 The left figure shows a schematic diagram of network resource reservation, where each rectangular bar in the figure represents a network resource reservation strategy for a service data flow, wherein the height of the rectangular bar in the vertical axis direction represents the reserved bandwidth, and the span of the rectangular bar in the horizontal axis direction represents the start time and end time of the reserved bandwidth; Figure 3The right figure shows a schematic diagram of computing resource reservation, where each rectangular bar in the figure represents a computing resource reservation strategy for a business data flow, where the height of the rectangular bar in the vertical axis represents the reserved computing resources, and the span of the rectangular bar in the horizontal axis represents the start time and end time of the reserved computing resources.

[0156] After the first network node sends the resource reservation policy to the first computing node, since network resources and computing resources may be updated, the previously formulated resource reservation policy may not meet business needs after the update. Therefore, it is necessary to dynamically adjust the reservation duration of the reserved resources.

[0157] Based on this, in one embodiment, after reserving the first computing resource for the first data flow, the method further includes:

[0158] receiving a third signaling; the third signaling being used to request adjustment of reserved resources corresponding to the first data flow;

[0159] Based on the third signaling, the reservation of the first computing resource is adjusted.

[0160] In one embodiment, the third signaling carries at least one of the following:

[0161] A first adjustment amount; the first adjustment amount is used to adjust the resource amount of the first computing resource;

[0162] A fourth time parameter; the fourth time parameter represents the adjusted reservation expiration time of the first computing resource;

[0163] A fifth time parameter; the fifth time parameter represents the adjusted network resource reservation termination time corresponding to the first data flow.

[0164] In this way, after receiving the third signaling, the first computing node adjusts the resource amount of the reserved first computing resource based on the first adjustment amount carried in the third signaling, and adjusts the reserved termination time of the first computing resource based on the fourth time parameter carried in the third signaling.

[0165] In actual application, when the resource reservation policy is initially issued, the reserved computing resources and the corresponding reservation duration are defined by extending the Object object in RSVP-TE, so that the first computing node can accurately reserve computing resources based on the corresponding computing resource reservation policy.

[0166] Based on this, in one embodiment, the CLASS NUM in the Object header of the first signaling is represented as a first type number; the first type number represents that the first signaling is used to request to reserve computing resources; or,

[0167] The first signaling is also used to request to reserve network resources for the first data flow; the CLASS NUM in the Object header of the first signaling represents a second type number; the second type number represents that the first signaling is used to request to reserve computing resources and network resources.

[0168] Based on the extended protocol format described above, when the network state or the running state of the computing node changes, the CLASS NUM of the Object header of the third signaling is the same as the CLASS NUM of the Object header of the first signaling; or,

[0169] The CLASS NUM in the Object header of the third signaling indicates a third type number; the third type number indicates that the third signaling is used to request adjustment of reserved resources.

[0170] Accordingly, the embodiment of the present application also provides a resource reservation method, which is applied to the second network node, such as Figure 4 As shown, the method includes:

[0171] Step 401: After the first network node sends the first signaling to the first computing node, the third signaling is sent; the third signaling is used to request adjustment of the reserved resources corresponding to the first data flow; wherein,

[0172] The first signaling is at least used to request to reserve a first computing resource for a first data stream; the first signaling carries a first time parameter and a second time parameter; the first time parameter represents a reservation start time of the first computing resource; and the second time parameter represents a reservation end time of the first computing resource.

[0173] Here, when the network state or the computing node state changes, the network node on the transmission path of the first data flow may initiate adjustment of the resource reservation policy. Here, the network node that may initiate adjustment of the resource reservation policy includes one of the following:

[0174] Control nodes;

[0175] Intermediate routing nodes;

[0176] Inter-domain router.

[0177] Here, the second network node re-determines the resource reservation amount and the corresponding reservation start and end time based on the real-time network status and the operation status of the computing node. Specifically, when the real-time network delay is greater than the network delay when the network resource reservation strategy is initially formulated, it is necessary to apply for an extension of the network resource reservation, and the network resource reservation termination time is correspondingly postponed. At the same time, since the service data reaches the computing node only after passing through the forwarding path, the delay of the network resource reservation termination time will also lead to the delay of the computing resource reservation termination time. In this case, both the network resource reservation termination time and the computing resource reservation termination time need to be adjusted accordingly; when the real-time computing delay is greater than the computing delay when the computing resource reservation strategy is initially formulated, it is necessary to apply for an extension of the computing resource reservation, and the computing resource reservation termination time is correspondingly postponed. In addition, when the status of the computing node changes, it may also bring about a change in the computing resource reservation amount, and the computing resource reservation amount needs to be adjusted accordingly.

[0178] Based on this, the third signaling carries at least one of the following:

[0179] A first adjustment amount; the first adjustment amount is used to adjust the resource amount of the first computing resource reserved for the first data flow;

[0180] A fourth time parameter; the fourth time parameter represents the adjusted reservation expiration time of the first computing resource;

[0181] A fifth time parameter; the fifth time parameter represents the adjusted network resource reservation termination time corresponding to the first data flow.

[0182] Based on the extended protocol format above, when the network state or the running state of the computing node changes, the CLASS NUM of the Object header of the third signaling is the same as the CLASS NUM of the Object header of the first signaling; the first signaling is used to request to reserve a first computing resource and / or network resource for the first data flow; or,

[0183] The CLASS NUM in the Object header of the third signaling indicates a third type number; the third type number indicates that the third signaling is used to request adjustment of reserved resources.

[0184] Figure 5 The schematic diagram of the implementation process of the resource reservation method provided by the application embodiment of the present application is shown. Figure 5 , the implementation process includes:

[0185] Step 1: The terminal sends a service request to the Controller, which carries the corresponding service requirements.

[0186] Step 2: The Controller maps business requirements into network resource requirements and computing resource requirements.

[0187] Step 3: The Controller determines the corresponding network resource reservation strategy and computing resource reservation strategy based on the mapped network resource requirements and computing resource requirements.

[0188] Step 4: The Controller sends the network resource reservation policy and computing resource reservation policy. The policy includes the corresponding network resource reservation start and end time and computing resource reservation start and end time.

[0189] Step 5: Based on the issued network resource reservation policy, the network resources on the forwarding path return a reservation success response to the Controller and maintain the corresponding network resource reservation table locally to achieve accurate reservation of network resources based on the network resource reservation table.

[0190] Step 6: Based on the computing resource reservation policy issued, the computing node returns a reservation success response to the Controller and maintains the corresponding computing resource reservation table locally to achieve accurate reservation of computing resources based on the computing resource reservation table.

[0191] The resource reservation method provided in the embodiment of the present application is that the first network node sends a first signaling to the first computing node, wherein the first signaling is at least used to request to reserve computing resources for the first data flow; the first signaling is at least used to request to reserve the first computing resource for the first data flow; the first signaling carries a first time parameter and a second time parameter; the first time parameter represents the reservation start time of the first computing resource; the second time parameter represents the reservation end time of the first computing resource. The first computing node reserves the first computing resource for the first data flow based on the first time parameter and the second time parameter. Through the reservation of computing resources, the business data can have sufficient computing power guarantee on the computing node. And, in combination with business needs and network status, the running status of the computing node, the accurate reservation of computing resources can be achieved. In addition, by dynamically adjusting the resource reservation strategy, the autonomy of the network node in the business process is increased, and timely adjustments can be made based on the real-time network status and the running status of the computing node, thereby further guaranteeing the business needs on the basis of network resource reservation, while improving the utilization rate of network resources and computing resources.
