Description

Bandwidth processing method and device

Technical Field

The present disclosure relates to the field of communications, and in particular, to a method and apparatus for processing bandwidth.

Background

For nodes in the network, it may send data (e.g., traffic data) to other nodes, or may receive data sent by other nodes. Wherein a node may communicate with other nodes via an interface.

For an interface, the bandwidth of the interface is limited, and how to guarantee the corresponding service quality (quality of service, qoS) of the service transmitted by the interface is a problem yet to be solved.

Disclosure of Invention

The embodiment of the application provides a bandwidth processing method, which can ensure the service quality provided for a service as far as possible under the condition that a plurality of communication devices send service data to a first interface of a second communication device.

In a first aspect, an embodiment of the present application provides a bandwidth processing method, which may be applied to a first communication device. In one example, the first communication device may obtain a first bandwidth weight, where the first bandwidth weight is used to instruct the first communication device to send data to a first interface of the second communication device, where the first interface bandwidth is a downlink bandwidth of the first interface. The first communication device may also acquire the first interface bandwidth. After the first communication device obtains the first bandwidth weight and the first interface bandwidth, the first bandwidth may be determined according to the first interface bandwidth and the first bandwidth weight. It can be seen that, by using the scheme of the embodiment of the present application, the first bandwidth of the data sent by the first communication device to the first interface may be determined according to the first bandwidth weight and the first interface bandwidth, in this manner, the first bandwidth may be "planned", and in one example, this planning manner may avoid that the first communication device sends a large amount of service data to the first interface, and accordingly, avoid that the actual downlink bandwidth of the first interface exceeds the first interface bandwidth, so that part of the service data is discarded; in yet another example, in this planning manner, the first bandwidth may ensure a bandwidth requirement of the first communication device for sending service data to the first interface, so that quality of service of a service corresponding to the service data sent by the first communication device to the first interface may be ensured.

In one possible implementation, the first communication device may receive a first bandwidth weight sent by a controller. After the first communication device receives the first bandwidth weight sent by the controller, the first bandwidth weight may be saved so as to determine the first bandwidth based on the first bandwidth weight.

In one possible implementation, the controller may send a message including an identification of the first interface and the first bandwidth weight to a first communication device, thereby enabling retransmission of the first bandwidth weight to the first communication device. The identifier of the first interface in the message is used for enabling the first communication device to determine that the first bandwidth weight is used for indicating a ratio between a first bandwidth of the first communication device for sending data to the first interface of the second communication device and the first interface bandwidth. In one example, the message may include a configuration template, where the configuration template includes the first bandwidth weight and the identification of the first interface. In other words, in one example, the first communication device receiving the first bandwidth weight sent by the controller may, when embodied, receive a configuration template sent by the controller, the configuration template including the first bandwidth weight and an identification of the first interface.

In one possible implementation manner, after the first communication device receives the configuration template, the first interface bandwidth sent by the second communication device and the first bandwidth weight in the configuration template may be associated by using the identifier of the first interface in the configuration target, that is: the first communication device may determine, based on the identification of the first interface, that the bandwidth of the first interface is a bandwidth of the first interface, and determine that a ratio of a bandwidth of itself sending service data to the first interface to the bandwidth of the first interface is a first bandwidth weight. After the first communication device associates the first interface bandwidth with the first bandwidth weight in the configuration template, the first bandwidth may be determined based on the first interface bandwidth and the first bandwidth weight.

In one possible implementation manner, in order to facilitate reasonable planning of the bandwidth of the service data sent to the first interface by the first communication device, the configuration template may further include: and the bandwidth corresponding to at least one service deployed on the first communication device. The at least one service mentioned here may be a service transmitted between the first communication device and the second communication device, or the at least one service mentioned here may be a service corresponding to service data sent by the first communication device to the first interface. In one example, the configuration template may include a specific value of bandwidth corresponding to at least one service deployed on the communication device. In yet another example, the configuration template may include a ratio between the bandwidth corresponding to the at least one service and the first bandwidth.

In one possible implementation, the first communication device may receive first information sent by the second communication device, so as to obtain the first interface bandwidth, where the first information may be used to indicate the first interface bandwidth. In one example, the first information may be the first interface bandwidth itself, and in yet another example, the first information may be other indication information that enables the first communication device to determine the first interface bandwidth. For example, the first communication device may store a correspondence between the first information and the first interface bandwidth, and after the first communication device receives the first information, the first communication device may determine the first interface bandwidth based on the first information and the correspondence.

In one possible implementation, the second communication device may send the first information to the first communication device in a control message. The embodiment of the application is not particularly limited to the control message, for example, a new control message may be redefined, and the second communication device carries the first information in the new control message and sends the new control message to the first communication device. As another example, an existing control message may be extended, extending a new field, such as a type length value (type length value, TLV), to carry the first information. For another example, the reserved field or other fields not yet used in the existing control message may be utilized to carry the first information.

In one possible implementation, the control message may be a border gateway protocol (Border Gateway Protocol, BGP) message. For this case, the second communication device may send the first interface bandwidth to the first communication device via the BGP message.

In one possible implementation, the BGP message is used to advertise BGP routes. In other words, BGP routes may be carried in the BGP message, and in this case, by sending the BGP message to the first communication device, the second communication device both announces the BGP route to the first communication device and transmits the first interface bandwidth to the first communication device.

In one possible implementation, the BGP route may be a BGP EVPN route considering that both the first communication device and the second communication device may configure ethernet virtual private network (ethernet virtual private network, EVPN) traffic. In one example, the BGP EVPN route referred to herein may be a BGP EVPN route after expanding a standard BGP EVPN route. For example, in one example, a standard BGP EVPN route may be extended, with new fields being extended to carry the first information.

In one possible implementation manner, in order to improve the quality of service that the first communication device can provide for the service deployed on the first communication device as much as possible, the first communication device may dynamically adjust the first bandwidth according to an actual required bandwidth of the first communication device for sending service data to the first interface, so that the bandwidth of the first communication device for sending the service to the first interface better conforms to the actual required bandwidth, and accordingly, the quality of service that the first communication device can provide for the service deployed on the first communication device is improved.

In one possible implementation manner, if the actual required bandwidth is greater than the first bandwidth, the first communication device may increase the first bandwidth, so that the bandwidth of the service sent by the first communication device to the first interface better conforms to the actual required bandwidth.

In one possible implementation, it is contemplated that in addition to the first communication device sending traffic data to the first interface, other communication devices may also send traffic data to the first interface. Therefore, if the first communication device dynamically adjusts the first bandwidth based on its own actual required bandwidth, the actual downlink bandwidth of the first interface may exceed the first bandwidth of the first interface, and accordingly, the service quality of the first link may be degraded. For example, the delay of the first link is increased, the packet loss rate is increased, and so on. The first link is a link between the first communication device and the first interface, and the first communication device can send service data to the first interface through the first link. The service level agreement (service level agreement, SLA) parameters of the first link may represent the service quality of the first link, and the corresponding SLA parameters of the first link may represent whether the actual downlink bandwidth of the first interface exceeds the first bandwidth of the interface. Thus, in one example, the first communication device may dynamically adjust the first bandwidth based on the actual required bandwidth of the traffic data and the SLA parameters of the first link that the first communication device sends to the first interface.

In one possible implementation manner, if the actual required bandwidth of the first communication device is greater than the first bandwidth and the SLA parameter of the first link indicates that the service quality of the first link is not degraded, it is indicated that the actual downlink bandwidth of the first interface does not exceed the first interface bandwidth, and in this case, the first communication device may increase the first bandwidth, so as to meet the bandwidth requirement of the first communication device for sending service data to the first interface as much as possible.

In one possible implementation manner, if the actual required bandwidth of the first communication device is smaller than the first bandwidth and the SLA parameter of the first link indicates that the service quality of the first link is degraded, the first communication device may reduce the detection period of the SLA parameter of the first link, that is: the frequency of detecting SLA parameters is increased to further determine the cause of degradation in the quality of service of the first link, and thus the subsequent bandwidth adjustment policy.

In one possible implementation, if the SLA parameters detected by the first communication device in N detection periods after the detection period of the SLA parameters are reduced indicate that the service quality of the first link is degraded, it is indicated that the reason for the degradation of the service quality of the first link may be that the bandwidth of the first interface is reduced. For this case, the first communication device may reduce the first bandwidth, so as to avoid that the actual downlink bandwidth of the first interface exceeds the reduced first interface bandwidth, and accordingly, avoid that the service quality of the first link is degraded. Reference herein to N is an integer greater than or equal to 1, for example, where N is 10.

In one possible implementation manner, the second communication device may detect an actual downlink bandwidth of the first interface, and when the actual downlink bandwidth of the first interface is greater than the first interface bandwidth, the second communication device may send indication information to the first communication device, where the indication information is used to instruct the first communication device to dynamically adjust the first bandwidth. In one example, the second communication device may send an indication message carrying the indication information to the first communication device. The indication information may be carried in a header of the indication message, and when the indication information includes tunnel encapsulation information, the indication information may also be carried in the tunnel encapsulation information, which is not specifically limited in the embodiment of the present application. Correspondingly, the first communication device may receive the indication information sent by the second communication device, and dynamically adjust the first bandwidth further based on the indication information, so that after the first bandwidth is adjusted, the actual downlink bandwidth of the first interface is smaller than or equal to the first interface bandwidth.

In one possible implementation, the first communication device dynamically adjusts the first bandwidth based on the indication information, and when the first bandwidth is specific, the first communication device may reduce the first bandwidth to, for example, an initial value of the first bandwidth when the first bandwidth is greater than the initial value of the first bandwidth. Since the first bandwidth is reduced, the actual downlink bandwidth of the first interface is correspondingly reduced, and further, the actual downlink bandwidth of the first interface may be smaller than or equal to the first interface bandwidth.

In one possible implementation manner, in order to ensure the service quality of the first link as much as possible, the first communication device dynamically adjusts the first bandwidth based on the indication information, and when in specific implementation, the first bandwidth may be adjusted in combination with SLA parameters of the first link, that is: the quality of service of the first link is considered when the first bandwidth is adjusted, so that the quality of service of the first link is improved after the first bandwidth is adjusted.

In one possible implementation, if the SLA parameter indicates that the service quality of the first link is degraded and the first bandwidth is greater than an initial value of the first bandwidth, this indicates that the actual downlink bandwidth of the first interface exceeds the first interface bandwidth, which may be caused by the first communication device increasing the initial bandwidth to the first bandwidth, and in this case, the first communication device may decrease the first bandwidth in order to make the actual downlink bandwidth of the first interface smaller than or equal to the first interface bandwidth.

In one possible implementation, if the SLA parameter of the first link indicates that the service quality of the first link is not degraded, it indicates that the service quality of the first link can still be guaranteed although the actual downlink bandwidth of the first interface exceeds the first interface bandwidth. For this case, the first communication device may not make an adjustment to the first bandwidth. However, since the actual downlink bandwidth of the first interface exceeds the first interface bandwidth, the quality of service of the first link may be affected, and in this regard, in one example, the first communication device may reduce the detection period of the SLA parameter of the first link, that is: the detection frequency of the SLA parameters of the first link is quickened, so that when the service quality of the first link is changed, the first communication device can timely determine the change of the service quality, and then a subsequent bandwidth adjustment strategy is determined.

In one possible implementation manner, if the SLA parameters detected by the first communication device in N detection periods after the detection period of the SLA parameters are reduced indicate that the service quality of the first link is not degraded, it is indicated that the service quality of the first link is relatively stable. Whereas high frequency detection of the SLA parameters consumes excessive computing resources of the first communication device, the first communication device may for this case reduce the detection period for restoring the SLA parameters, thereby saving computing resources of the first communication device.

In one possible implementation, the first communication device is a central hub node and the second communication device is a branch spoke node. In this way, although the interface bandwidth of the hub node is far greater than the interface bandwidth of the spoke node (for example, the interface bandwidth of the hub node for the interface interacting with the spoke is far greater than the first interface bandwidth), by adopting the scheme, the bandwidth of the hub node for sending data to the spoke node can be planned, so that part of service data is discarded because the actual downlink bandwidth of the first interface of the spoke node exceeds the first interface bandwidth, and in addition, the service quality of the service corresponding to the service data sent to the first interface by the hub node can be ensured.

In one possible implementation, the first communication device may send data to a second interface of the third communication device in addition to the first interface, and accordingly, other communication devices may send data to the second interface. For this case, the first communication device may plan the bandwidth for transmitting traffic data to the second interface. As an example, the first communication device may obtain a second bandwidth weight and a second interface bandwidth, where the second bandwidth weight is used to instruct the first communication device to send data to a second interface of a third communication device, and the second interface bandwidth is a ratio between the second bandwidth and the second interface bandwidth, where the second interface bandwidth is a downlink bandwidth of the second interface; and determining the second bandwidth according to the second interface bandwidth and the second bandwidth weight.

In a second aspect, embodiments of the present application provide a bandwidth processing method, which may be applied to a second communication device. In one example, the second communication device may determine a first interface bandwidth, which is a downlink bandwidth of a first interface of the second communication device, through which the second communication device communicates with a first communication device, in other words, the first communication device may transmit traffic data to the first interface. After the second communication device determines the first interface bandwidth, the first interface bandwidth may be transmitted to the first communication device. In one example, the first communication device may plan a first bandwidth over which it sends traffic data to the first interface based on the first interface bandwidth, e.g., determine the first bandwidth based on the first interface bandwidth and a first bandwidth weight. In one example, the planning manner can avoid that the first communication device sends a large amount of service data to the first interface, and correspondingly, avoid that the actual downlink bandwidth of the first interface exceeds the bandwidth of the first interface so that part of the service data is discarded; in yet another example, in this planning manner, the first bandwidth may ensure a bandwidth requirement of the first communication device for sending service data to the first interface, so that quality of service of a service corresponding to the service data sent by the first communication device to the first interface may be ensured.

In one possible implementation manner, the sending the first interface bandwidth to the first communication device includes: and sending a control message to the first communication device, wherein the control message comprises the first interface bandwidth.

In one possible implementation, the method further includes: and sending indication information to the first communication device under the condition that the actual downlink bandwidth of the first interface is larger than the first interface bandwidth, wherein the indication information is used for indicating the first communication device to dynamically adjust the first bandwidth of the first communication device for sending data to the first interface.

In one possible implementation, in addition to processing the first communication device, the third communication device may also send data to the first interface, in which case the second communication device may also send the first interface bandwidth to the third communication device, so that the third communication device uses the first interface bandwidth to plan the bandwidth of itself sending data to the first interface.

In one possible implementation, the first communication device is a first central hub node, the third communication device is a second hub node, and the second communication device is a branch spoke node.

In a third aspect, embodiments of the present application provide a bandwidth processing method, which may be applied to a controller. In one example, the controller may obtain a first bandwidth weight that is used to instruct a first communication device to send data to a first interface of a second communication device, where the first interface bandwidth is a downlink bandwidth of the first interface. After acquiring the first bandwidth weight, the controller may retransmit the first bandwidth weight to the first communication device. In one example, the first communication device may plan a first bandwidth over which it sends traffic data to the first interface based on the first bandwidth weight, e.g., determine the first bandwidth from the first interface bandwidth and the first bandwidth weight. In one example, the planning manner can avoid that the first communication device sends a large amount of service data to the first interface, and correspondingly, avoid that the actual downlink bandwidth of the first interface exceeds the bandwidth of the first interface so that part of the service data is discarded; in yet another example, in this planning manner, the first bandwidth may ensure a bandwidth requirement of the first communication device for sending service data to the first interface, so that quality of service of a service corresponding to the service data sent by the first communication device to the first interface may be ensured.

In one possible implementation manner, the retransmitting the first bandwidth right to the first communication device includes: a configuration template is sent to the first communication device, the configuration template including the first bandwidth weight and an identification of the first interface.

In one possible implementation, the configuration template further includes: and the bandwidth corresponding to at least one service deployed on the first communication device.

In one possible implementation, for a third communication device that may send data to a first interface, the controller may further send a second bandwidth weight to the third communication device, the second bandwidth weight being used to indicate a ratio between a second bandwidth of the third communication device sending data to the first interface and the first interface bandwidth. Accordingly, the third communication device may plan a second bandwidth for transmitting data to the first interface based on the second bandwidth weight.

In one possible implementation, the first communication device may send data to the second interface of the fourth communication device in addition to the first interface. Similarly, other communication devices may also send data to the second interface. For this case, the controller may further transmit a third bandwidth weight to the first communication device, the third bandwidth weight being used to instruct the first communication device to transmit data to a second interface, the second interface bandwidth being a downstream bandwidth of the second interface, to a ratio between a third bandwidth of the second interface and a second interface bandwidth. Accordingly, the first communication device may plan a third bandwidth for transmitting data to the second interface based on the third bandwidth weight.

Detailed Description

For a node in the network, it may communicate with other nodes through interfaces. The interface bandwidth of the interface is limited, and at present, the uplink bandwidth of the interface can be planned. For example, when the uplink bandwidth is limited, service data of the high priority service is preferentially transmitted. As another example, the upstream bandwidth is divided, different bandwidth guarantees are provided for different departments, and so on.

However, in some scenarios, the above manner of planning the uplink bandwidth cannot guarantee the quality of service provided for the service. For example, it may be understood with reference to fig. 1, where fig. 1 is a schematic view of an exemplary application scenario provided in an embodiment of the present application.

In the scenario shown in fig. 1, both communication device 110 and communication device 120 may send traffic data to interface 131 of communication device 130. In one example, communication device 110 may send traffic data to interface 131 using interface 111 and communication device 120 may send traffic data to interface 131 using interface 121. If the total bandwidth of the traffic data transmitted from the communication device 110 and the communication device 120 to the interface 131 exceeds the downstream bandwidth of the interface 131, the forwarding apparatus discards a part of the traffic data when transmitting the traffic data transmitted from the communication device 110 and the communication device 120 to the interface 131. And, when the forwarding device discards the service data, the service priority corresponding to the discarded service data is not considered. Therefore, in this scenario, the service data of the high priority service may be discarded, so that the quality of service provided for the service corresponding to the service data received by the interface 131 may not be guaranteed, and in particular, the quality of service provided for the aforementioned high priority service may not be guaranteed.

In one example, communication device 110 and communication device 120 may each correspond to a hub node, and communication device 130 corresponds to a spoke node. For this case, because the interface bandwidth of hub nodes is relatively large, it is often much larger than the interface bandwidth of spoke nodes. Therefore, in this case, when the communication device 110 and the communication device 120 corresponding to the hub node send a large amount of service packets to the interface 131, the total bandwidth of the communication device 110 and the communication device 120 for sending service data to the interface 131 may be far greater than the downlink bandwidth of the interface 131, and accordingly, the service quality provided for the service corresponding to the service data received by the interface 131 may not be ensured, especially the service quality provided for the high priority service may not be ensured, because the forwarding device discards the service data regardless of the priority of the service.

In addition, the communication device 110 may transmit traffic data to other communication devices in addition to the communication device 130, and as shown in fig. 1, the communication device 110 may transmit traffic data to the interface 141 of the communication device 140 using the interface 112. Similarly, other communication devices, such as communication device 120 shown in FIG. 1, may also send traffic data to interface 141 using interface 121, or other communication devices not shown in FIG. 1 may also send data to interface 141. For this case, when the downstream traffic of the interface 141 exceeds the downstream bandwidth of the interface 141, the quality of service provided for the service corresponding to the service data received by the interface 141 cannot be guaranteed, and in particular, the quality of service provided for the high priority service may not be guaranteed.

In one example, the communication device 140 may correspond to a spoke node.

The interfaces mentioned in the embodiments of the present application may be physical interfaces.

It should be noted that fig. 1 is only one of the scenarios to which the present solution may be applied, and the scenario to which the solution provided in the embodiment of the present application is applicable is not limited to the scenario shown in fig. 1.

In order to solve the above-mentioned problem, the embodiment of the present application provides a bandwidth processing method, and next, with reference to fig. 2, the bandwidth processing method provided by the embodiment of the present application is described.

Before describing the method 100 shown in fig. 2, it should be noted that:

the communication apparatus (for example, the communication apparatus 1, the communication apparatus 2, and the like mentioned below) mentioned in the embodiment of the present application may be a network device such as a switch, a router, or a part of components on the network device, for example, a board, a line card, or a functional module on the network device, or a chip for implementing the method of the present application, and the embodiment of the present application is not specifically limited. The communication devices may be directly connected to each other, for example, but not limited to, via an ethernet cable or an optical cable.

Referring to fig. 2, fig. 2 is a signaling interaction diagram of a bandwidth processing method according to an embodiment of the present application. The bandwidth processing method 100 shown in fig. 2 may include, for example, the following S101-S107.

In one example, communication device 1 in method 100 may correspond to communication device 110 shown in fig. 1, communication device 2 in method 100 may correspond to communication device 130 shown in fig. 1, and interface 1 in method 100 may correspond to interface 131 shown in fig. 1.

In another example, communication device 1 in method 100 may correspond to communication device 110 shown in fig. 1, communication device 2 in method 100 may correspond to communication device 140 shown in fig. 1, and interface 1 in method 100 may correspond to interface 141 shown in fig. 1.

In yet another example, communication device 1 in method 100 may correspond to communication device 120 shown in fig. 1, communication device 2 in method 100 may correspond to communication device 130 shown in fig. 1, and interface 1 in method 100 may correspond to interface 131 shown in fig. 1.

In another example, communication device 1 in method 100 may correspond to communication device 120 shown in fig. 1, communication device 2 in method 100 may correspond to communication device 140 shown in fig. 1, and interface 1 in method 100 may correspond to interface 141 shown in fig. 1.

S101: the controller obtains a bandwidth weight 1, where the bandwidth weight 1 is used to instruct the communication device 1 to send data to the interface 1 of the communication device 2, and the ratio between the bandwidth 1 of the interface and the bandwidth 1 of the interface, and the bandwidth 1 of the interface is the downlink bandwidth of the interface 1.

In one example, the bandwidth weight 1 may be user-specified, e.g., the controller may obtain user input of the bandwidth weight 1. The bandwidth weight 1 is not particularly limited, and the bandwidth weight 1 may be a value greater than 0 and less than 1, for example, the bandwidth weight 1 may be 0.6.

S102: the controller sends the bandwidth weight 1 to the communication device 1.

After the controller obtains the bandwidth weight 1, the bandwidth weight 1 may be sent to the communication device 1, so that the communication device 1 reasonably plans the bandwidth of sending the service data to the interface 1 based on the bandwidth weight 1.

In one example, the controller may send a message to the communication device 1 including the identification of the interface 1 and the bandwidth weight 1, thereby enabling the bandwidth weight 1 to be sent to the communication device 1. The identity of the interface 1 in the message is used to enable the communication device 1 to determine that the bandwidth weight 1 is used to instruct the communication device 1 to send data to the interface 1 of the communication device 2 and the ratio between the bandwidth 1 of the interface and the bandwidth 1 of the interface.

In one example, the foregoing message may include a configuration template, where the configuration template includes the identity of the interface 1 and the bandwidth weight 1.

In yet another example, in order to facilitate reasonable planning of the bandwidth of the service data sent to the interface 1 by the communication device 1, the configuration template may further include: bandwidth corresponding to at least one service deployed on the communication device 1. The at least one service deployed on the communication device 1 mentioned here may be a service transmitted between the communication device 1 and the communication device 2, or the at least one service deployed on the communication device 1 mentioned here may be a service corresponding to service data sent by the communication device 1 to the interface 1. In one example, the configuration template may include a specific value of bandwidth corresponding to at least one service deployed on the communication device. For this case, in one example, the specific value of the bandwidth corresponding to the high priority service may be larger than the specific value of the bandwidth corresponding to the low priority service, so that the communication apparatus 1 may preferentially guarantee the quality of service provided for the high priority service. In yet another example, the configuration template may include a ratio between the bandwidth corresponding to the at least one service and the bandwidth 1. For this case, in one example, the ratio corresponding to the high priority service is higher than the ratio corresponding to the low priority service, so that the communication apparatus 1 can preferentially secure the quality of service provided for the high priority service.

S103: the communication device 1 receives the bandwidth weight 1 transmitted by the controller.

The controller transmits the bandwidth weight 1 to the communication device 1, and accordingly, the communication device 1 may receive the bandwidth weight 1 transmitted by the controller. In one example, after receiving the bandwidth weight 1, the communication apparatus 1 may save the correspondence between the identification of the interface 1 and the bandwidth 1.

S104: the communication device 2 determines the interface bandwidth 1 of the interface 1.

In one example, the interface bandwidth 1 may be configured locally to the communication device 2, and thus, the communication device 2 may obtain the interface bandwidth 1 that is pre-configured.

In yet another example, the interface bandwidth 1 may be that which the controller sends to the communication device 2, for which case the communication device 2 may receive the interface bandwidth 1 sent by the controller.

S105: the communication device 2 transmits the interface bandwidth 1 to the communication device 1.

S106: the communication device 1 receives the interface bandwidth 1 transmitted by the communication device 2.

After the communication device 2 obtains the interface bandwidth 1, the interface bandwidth 1 may be sent to the communication device 1, so that the communication device 1 reasonably plans the bandwidth of sending service data to the interface 1 based on the bandwidth weight 1.

In one example, the communication device 2 may directly send the interface bandwidth 1 to the communication device 1, and the communication device 2 may also send the interface bandwidth 1 to the communication device 1 through other devices, which is not specifically limited in the embodiment of the present application. For example, in one example, the communication device 2 may send the interface bandwidth 1 to the communication device 1 through a Route Reflector (RR).

In one example, the communication device 2 may send information 1 indicative of the interface bandwidth 1 to the communication device 1, thereby enabling the interface bandwidth 1 to be sent to the communication device 1. In one example, the communication device 2 may send the information 1 carrying the interface bandwidth 1 to the communication device 1 in a control message. Accordingly, the communication device 1 may receive the control message including the information 1 sent by the communication device 2. The embodiment of the present application is not particularly limited to the control message, for example, a new control message may be redefined, and the information 1 is carried in the new control message and sent to the communication device 1. As another example, an existing control message may be extended, and a new field (e.g., TLV) may be extended to carry the information 1. For another example, the information 1 may be carried by a reserved field in an existing control message or other fields that have not yet been used. The information 1 mentioned here may be used to indicate the interface bandwidth 1, where the information 1 may be the interface bandwidth 1 itself, or may be other indication information that can be used to enable the communication device 1 to determine the interface bandwidth 1, and the embodiment of the present application is not specifically limited. For example, the communication device 1 may locally store a correspondence between the information 1 and the interface bandwidth 1, and after the communication device 1 receives the information 1, the interface bandwidth 1 may be determined based on the correspondence.

In one example, the control message may be a BGP message. For this case, in one example, BGP messages may be extended, extending a new extended community attribute to carry the interface bandwidth 1. In this way, the communication device 2 can transmit the interface bandwidth 1 to the communication device 1 using the BGP message.

In one example, the BGP message may be used to advertise BGP routes, in other words, the BGP message may carry BGP routes, in which case the communication device 2 both advertises BGP routes to the communication device 1 and communicates the interface bandwidth 1 to the communication device 1 by sending the BGP message to the communication device 1. The BGP route is not particularly limited in the embodiments of the present application, and in one example, it is considered that both the communication apparatus 1 and the communication apparatus 2 may configure EVPN traffic, and thus, the BGP route may be a BGP EVPN route. In one example, the BGP EVPN route referred to herein may be a BGP EVPN route after expanding a standard BGP EVPN route. For example, in one example, a standard BGP EVPN route may be extended, with a new field extended to carry information 1.

S107: the communication device 1 determines the bandwidth 1 of the communication device 1 for transmitting data to the interface 1 based on the received interface bandwidth 1 and the bandwidth weight 1.

After the communication device 1 receives the interface bandwidth 1 transmitted by the communication device 2 and the bandwidth weight 1 transmitted by the controller, the bandwidth 1 for transmitting service data to the interface 1 can be determined based on the interface bandwidth 1 and the bandwidth weight 1. In one example, the communication device 1 may determine the product of the interface bandwidth 1 and the bandwidth weight 1 as the bandwidth 1. For example, the interface bandwidth 1 is 100 megabytes per second (megabyte per second, mps) and the bandwidth weight 1 is 0.6, the communication device 1 can determine that the bandwidth in which it transmits traffic data to the interface 1 is 60Mps.

As previously described, in one example, the controller may send the communication device 1 a configuration template carrying an identification of the interface 1 and the bandwidth weight 1. For this case, in one example, the communication device 1 may associate the interface bandwidth 1 sent by the communication device 2 with the bandwidth weight 1 in the configuration template, i.e.: the communication device 1 may determine, based on the identification of the interface 1, that the bandwidth of the interface 1 is the interface bandwidth 1, and determine that the ratio of the bandwidth of itself sending service data to the interface 1 to the interface bandwidth 1 is the bandwidth weight 1. After the communication apparatus 1 associates the interface bandwidth 1 with the bandwidth weight 1 in the configuration template, the aforementioned bandwidth 1 may be determined based on the interface bandwidth 1 and the bandwidth weight 1.

It should be noted that the method 100 is only one implementation manner of the embodiment of the present application, and the solution provided by the embodiment of the present application is not limited to the embodiment shown in fig. 1. For example, in still another example, the aforementioned bandwidth weight 1 may be configured locally to the communication apparatus 1, and in this case, the communication apparatus 1 may acquire the bandwidth weight 1 configured locally in advance. In yet another example, the aforementioned interface bandwidth 1 may be configured locally to the communication device 1, in which case the communication device 1 may obtain the interface bandwidth 1 that is configured locally in advance.

In one example, in order to enhance the quality of service that the communication device 1 can provide for the service deployed on the communication device 1 as much as possible, the communication device 1 may dynamically adjust the bandwidth 1 according to the actual required bandwidth of the communication device 1 for sending the service data to the interface 1, so that the bandwidth of the communication device 1 for sending the service to the interface 1 better conforms to the actual required bandwidth, and accordingly, the quality of service that the communication device 1 can provide for the service deployed on the communication device 1 is enhanced.

In one example, if the aforementioned actual demand bandwidth is greater than the aforementioned bandwidth 1, the communication device 1 may increase the aforementioned bandwidth 1. For example, the bandwidth 1 is 60Mps, and the actual required bandwidth is 70Mps, the communication device 1 may increase the bandwidth 1 from 60Mps to 70Mps.

In one example, it is contemplated that other communication devices may send traffic data to interface 1 in addition to communication device 1 sending traffic data to interface 1. Therefore, if the communication device 1 dynamically adjusts the bandwidth 1 based on its own actual required bandwidth, the actual downlink bandwidth of the interface 1 may exceed the interface bandwidth 1, and accordingly, the service quality of the link 1 may be degraded. For example, the delay of the link 1 is increased, the packet loss rate is increased, and so on. The link 1 is a link between the communication device 1 and the interface 1, and the communication device 1 may send service data to the interface 1 through the link 1. The SLA parameter of the link 1 may represent the service quality of the link 1, and the corresponding SLA parameter of the link 1 may represent whether the actual downlink bandwidth of the interface 1 exceeds the aforementioned interface bandwidth 1.

Thus, in one example, the communication device 1 may dynamically adjust the first bandwidth based on the actual required bandwidth of the traffic data sent by the communication device 1 to the interface 1 and the SLA parameters of the link 1 as described above.

The link 1 mentioned in the embodiment of the present application may be a tunnel. The tunnel referred to herein may be an overlay tunnel, which may be a tunnel created on the basis of a tunnel provided by a service provider, which may correspond to a physical link, while the overlay tunnel does not perceive the physical link. overlay tunnels include, but are not limited to, virtual extended local area network (virtual extensible local area network, VXLAN) tunnels, generic routing encapsulation (generic routing encapsulation, GRE) tunnels, and internet protocol security (Internet Protocol Security, IPSec) based GRE tunnels, which may also be referred to as GRE over IPSec tunnels.

The SLA parameters in the embodiments of the present application include, but are not limited to, one or more of delay, packet loss, jitter, and the like.

In one example, if the actual required bandwidth of the communication device 1 is greater than the bandwidth 1 and the SLA parameter of the link 1 indicates that the service quality of the link 1 is not degraded, it is indicated that the actual downlink bandwidth of the interface 1 does not exceed the interface bandwidth 1, and in this case, the communication device 1 may increase the bandwidth 1, so as to meet the bandwidth requirement of the communication device 1 for sending service data to the interface 1 as much as possible.

In one example, the communication device 1 may gradually increase the bandwidth 1, e.g., the communication device 1 may gradually increase the bandwidth 1 according to a preset weight. As an example, each time the communication device 1 increases the bandwidth 1, it is determined whether to continue to increase the bandwidth 1 based on the SLA parameter of the link 1, and if the SLA parameter indicates that the service quality of the link 1 is not degraded, the communication device 1 may continue to increase the bandwidth 1. The preset weights mentioned here may be weights with respect to the interface bandwidth 1. Illustrating:

the interface bandwidth 1 is 100Mps, the preset weight is 5%, the initial value of the bandwidth 1 is 60Mps, the communication device 1 firstly adjusts the bandwidth 1 to 65Mps, if the SLA parameter of the link 1 indicates that the service quality of the link 1 is not degraded after adjusting the bandwidth 1 to 65Mps, the communication device 1 continues to adjust the bandwidth 1 to 70Mps, and so on.

As described above, in addition to the communication apparatus 1 transmitting the service data to the interface 1, other communication apparatuses may transmit the service data to the interface 1. Therefore, if the bandwidth 1 increases without limitation, and the bandwidth approaches the interface bandwidth 1, the actual downstream bandwidth of the interface 1 may exceed the interface bandwidth 1. Thus, in one example, the bandwidth 1 may have an upper bandwidth limit that the increased bandwidth 1 cannot exceed when the communication device 1 increases the bandwidth 1. For example, the upper bandwidth limit is 80% of the interface bandwidth 1.

With respect to the preset weight and the bandwidth upper limit, it should be noted that, in one example, the preset weight and the bandwidth upper limit may be preconfigured on the communication device 1 or may be sent to the communication device 1 by the controller. For example, the controller may send the preset weight and the bandwidth weight 1' to the communication device 1 in a configuration template, where the bandwidth weight 1' is referred to herein, to indicate a bandwidth upper limit corresponding to the bandwidth 1, for example, the bandwidth upper limit is equal to a product of the bandwidth weight 1' and the interface bandwidth 1.

In one example, if the actual required bandwidth of the communication device 1 is smaller than the bandwidth 1 and the SLA parameter of the link 1 indicates that the service quality of the link 1 is degraded, the communication device 1 may reduce the detection period of the SLA parameter of the link 1, that is: the frequency of detecting SLA parameters is increased to further determine the cause of degradation in the quality of service of link 1 and thus the subsequent bandwidth adjustment policy.

In one example, if the SLA parameters detected by the communication apparatus 1 in N detection periods after the detection period of the SLA parameters are reduced indicate that the service quality of the link 1 is degraded, it may be stated that the reason for the degradation of the service quality of the link 1 is that the interface bandwidth 1 is reduced. For this case, the communication device 1 may reduce the bandwidth 1, so as to avoid that the actual downlink bandwidth of the interface 1 exceeds the reduced interface bandwidth 1, and accordingly, avoid that the service quality of the link 1 is degraded. Reference herein to N is an integer greater than or equal to 1, for example, where N is 10.

In one example, the communication device 1 may decrease the bandwidth 1 in a specific implementation, for example, the bandwidth 1 may be gradually decreased, for example, the communication device 1 may gradually decrease the bandwidth 1 according to a preset weight. As an example, each time the communication device 1 decreases the bandwidth 1, it is determined whether to continue to decrease the bandwidth 1 based on the SLA parameter of the link 1, and if the SLA parameter indicates that the service quality of the link 1 is degraded, the communication device 1 may continue to decrease the bandwidth 1. Illustrating:

the interface bandwidth 1 is 100Mps, the preset weight is 5%, the initial value of the bandwidth 1 is 60Mps, the communication device 1 firstly adjusts the bandwidth 1 to 55Mps, if the SLA parameter of the link 1 indicates that the service quality of the link 1 is degraded after adjusting the bandwidth 1 to 55Mps, the communication device 1 continues to adjust the bandwidth 1 to 50Mps, and so on.

In one example, it is considered that if the bandwidth 1 is infinitely reduced, for example to approximately 0, the communication device 1 cannot generate traffic data to the interface 1, resulting in an interruption of traffic data transmission. To avoid this problem, in one example, the bandwidth 1 may be provided with a bandwidth lower limit, and when the communication apparatus 1 decreases the bandwidth 1, the decreased bandwidth 1 cannot be lower than the bandwidth lower limit. For example, the lower bandwidth limit is 20% of the interface bandwidth 1.

With respect to the bandwidth lower limit, it should be noted that, in an example, the bandwidth lower limit may be preconfigured on the communication apparatus 1 or may be sent to the communication apparatus 1 by the controller. For example, the controller may send a bandwidth weight 1 "carried in a configuration template to the communication device 1, where bandwidth weight 1" is referred to herein, for indicating a bandwidth lower limit corresponding to bandwidth 1, e.g. equal to the product of bandwidth weight 1 "and interface bandwidth 1.

In one example, the communication device 2 may detect an actual downlink bandwidth of the interface 1, and when the actual downlink bandwidth of the interface 1 is greater than the interface bandwidth 1, the communication device 2 may send indication information to the communication device 1, where the indication information is used to instruct the communication device 1 to dynamically adjust the bandwidth 1. In one example, the communication device 2 may send an indication message carrying the indication information to the communication device 1. The indication information may be carried in a header of the indication message, and when the indication information includes tunnel encapsulation information, the indication information may also be carried in the tunnel encapsulation information, which is not specifically limited in the embodiment of the present application.

Correspondingly, the communication device 1 may receive the indication information sent by the communication device 2, and dynamically adjust the bandwidth 1 further based on the indication information, so that after the bandwidth 1 is adjusted, the actual downlink bandwidth of the interface 1 is smaller than or equal to the interface bandwidth 1.

In one example, the communication device 1 dynamically adjusts the bandwidth 1 based on the indication information, and when the bandwidth 1 is greater than the initial value of the bandwidth 1, the communication device 1 may reduce the bandwidth 1, for example, to reduce the bandwidth 1 to the initial value of the bandwidth 1. Since bandwidth 1 is reduced, the actual downstream bandwidth of the interface 1 is correspondingly reduced, and further, the actual downstream bandwidth of the interface 1 may be smaller than or equal to the interface bandwidth 1. For example, bandwidth 1 is 75Mps, and the initial value of bandwidth 1 is 60Mps, bandwidth 1 may be reduced, for example, bandwidth 1 may be reduced to 60Mps. The initial value of bandwidth 1 may also be referred to as the initial bandwidth.

In one example, in order to guarantee the quality of service of the link 1 as much as possible, the communication device 1 dynamically adjusts the bandwidth 1 based on the indication information, which in a specific implementation can be adjusted in combination with SLA parameters of the link 1, namely: the quality of service of link 1 is taken into account when adjusting bandwidth 1, so that the quality of service of link 1 is improved after bandwidth 1 is adjusted.

As an example, if the SLA parameter indicates that the quality of service of the link 1 is degraded and the bandwidth 1 is greater than the initial value of the bandwidth 1, for this case, it is explained that the actual downstream bandwidth of the interface 1 exceeds the interface bandwidth 1, possibly because the communication device 1 increases the initial bandwidth to the bandwidth 1, for this case, the communication device 1 may decrease the bandwidth 1 in order to make the actual downstream bandwidth of the interface 1 smaller than or equal to the interface bandwidth 1. For example, the communication apparatus 1 may reduce the bandwidth 1 to an initial value of the bandwidth 1. As another example, the communication device 1 may gradually decrease the bandwidth 1 according to a preset weight, which is not specifically limited in the embodiment of the present application. As for a specific implementation in which the communication apparatus 1 may gradually decrease the bandwidth 1 according to a preset weight, reference may be made to the above related description section, and the description is not repeated here.

As yet another example, if the SLA parameter of the link 1 indicates that the service quality of the link 1 is not degraded, it is indicated that the service quality of the link 1 can be guaranteed although the actual downlink bandwidth of the interface 1 exceeds the interface bandwidth 1. For this case, the communication apparatus 1 may not adjust the bandwidth 1. However, since the actual downstream bandwidth of the interface 1 exceeds the interface bandwidth 1, the quality of service of the link 1 may be affected, and in view of this, in one example, the communication device 1 may reduce the detection period of the SLA parameters of the link 1, namely: the detection frequency of the SLA parameters of the link 1 is accelerated so that when the quality of service of the link 1 changes, the communication device 1 can determine the change of the quality of service in time, thereby determining a subsequent bandwidth adjustment strategy. For example, when it is determined that the quality of service of the link 1 is degraded, the bandwidth 1 is reduced.

In one example, if the SLA parameters detected by the communication device 1 in N detection periods after the detection period of the SLA parameters are reduced indicate that the service quality of the link 1 is not degraded, it is indicated that the service quality of the link 1 is relatively stable. Whereas detecting the SLA parameter at high frequency consumes excessive computing resources of the communication device 1, the communication device 1 may reduce the detection period for recovering the SLA parameter for this case, thereby saving computing resources of the communication device 1.

As can be seen from the above description, by using the bandwidth adjustment method provided by the embodiments of the present application, the bandwidth 1 of the data sent by the communication device 1 to the interface 1 may be determined according to the bandwidth weight 1 and the interface bandwidth 1, in this manner, the bandwidth 1 may be "planned", and in one example, when the hub node corresponding to the communication device 1 and the spoke node corresponding to the communication device 2 correspond to the spoke node, even if the interface bandwidth corresponding to the hub node is far greater than the interface bandwidth 1 of the spoke node, the communication device 1 may be prevented from sending a large amount of service data to the interface 1, so that the actual downlink bandwidth of the interface 1 exceeds the interface bandwidth 1, and the service data is discarded. In yet another example, in this way, the bandwidth 1 may ensure the bandwidth requirement of the communication device 1 for sending service data to the interface 1, so that the service quality of the service corresponding to the service data sent by the communication device 1 to the interface 1 can be ensured.
