Description

Dynamic link aggregation implementation method and device and computer storage medium

Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a dynamic link aggregation implementation method and apparatus, and a computer storage medium.

Background technique

Link aggregation is the combination of two or more data channels into a single channel that appears as a single, higher bandwidth logical link. The logical link is generally used to connect one or more devices with high bandwidth requirements, such as a server or server farm that connects to the backbone network.

LACP (Link Aggregation Control Protocol) is a protocol for dynamic link aggregation based on the IEEE802.3ad standard. The LACP exchanges information with the peer through the LACPDU (Link Aggregation Control Protocol Data Unit) and the peer to determine which ports can be activated as member ports of the link aggregation.

In the prior art, after the LACP standard protocol of a port is enabled, the port advertises its system priority, system MAC address, port priority, port number, and operation key to the peer through sending LACPDUs. After receiving the information, the peer compares the information with the information saved by the other ports to select the port that can be aggregated as the member port of the aggregation link. Therefore, the two parties can agree to join or exit the dynamic aggregation group.

The LACP standard protocol can only determine whether to add a port to an aggregation group based on the physical status of the port. The description of the aggregation condition of the LACP standard protocol only focuses on the physical attributes of the port, that is, the port duplex mode, link state, and rate. If the attributes are all in accordance with the aggregation conditions, they are immediately added to the aggregation group. Therefore, the method of controlling the aggregation group according to the LACP standard protocol is biased toward the physical state of the port. The flexibility is relatively low and the utilization of the member ports of the aggregation group cannot be controlled.

detailed description

The present invention will be further described in detail below with reference to the accompanying drawings.

Embodiment 1:

Referring to FIG. 1 , this embodiment provides a method for implementing dynamic link aggregation. When controlling link aggregation, traffic related information of the current access side may be taken into consideration. This ultimately enables dynamic control of the aggregation group member ports. The dynamic link aggregation implementation method in this embodiment includes:

S101. Configure a traffic adjustment policy.

S102. Dynamically obtain traffic parameter information of the current access side.

S103. Determine an aggregation group bandwidth adjustment requirement according to the traffic parameter information and the traffic adjustment policy. The aggregation group is a logical port formed by multiple physical ports being aggregated through links.

S104. Dynamically adjust the number of member ports in the aggregation group according to the bandwidth requirement of the aggregation group.

The member port is the physical port included in the aggregation group.

In this embodiment, the traffic adjustment policy can be understood as a policy based on data related to traffic on the access side. The data related to the traffic on the access side includes, but is not limited to, the maximum bandwidth on the access side, the actual traffic on the access side, the historical traffic on the access side, and the data on the access side. The traffic adjustment policy is used to determine the conditions that the adjusted aggregation group bandwidth should meet. In order to further determine how to adjust the bandwidth of the aggregation group, and the adjustment of the bandwidth of the aggregation group is made closer to the actual needs, the current access side needs to be considered for the bandwidth. Therefore, in the embodiment S102, the current access side is dynamically acquired. The traffic parameter information, where the traffic parameter information can be understood as the data related to the traffic on the access side, including but not limited to the current traffic on the access side, the maximum bandwidth requirement on the access side, and the history of the access side. Traffic, etc. After the current traffic parameter information and the traffic adjustment policy are obtained, the requirements of the current access side can be clarified, the bandwidth adjustment of the aggregation group can be clarified, and the number of member ports in the aggregation group can be dynamically adjusted. It is foreseen that in the embodiment, the physical state of the port that is added to the aggregation group needs to meet the conditions for joining the aggregation group. In this embodiment, the member ports that join the aggregation group are selected in the ports whose physical states meet the requirements of the aggregation group. of.

It can be foreseen that in practice, the transmission of the data amount on the access side is dynamically changed, so the demand for bandwidth on the access side is also dynamically changed, and may increase or decrease. The traffic parameter information obtained in the embodiment S102 reflects the bandwidth requirement of the current access side. The bandwidth adjustment requirements of the aggregation group determined according to the traffic parameter information and the traffic adjustment policy in S103 include adding member ports and deleting member ports, increasing and decreasing. The quantity is dynamically determined as the actual situation changes.

The bandwidth of each member port of the aggregation group can be the same or different. When the bandwidth of the member ports is different, the number of member ports in the aggregation group can be dynamically adjusted according to the port. For the bandwidth of the member port to be added, for example, the bandwidth requirement of the aggregation group is +8M, that is, the bandwidth of the port is increased by 8M. In this case, the bandwidth of the port that can be added to the aggregation group is 10M and 1M. In this embodiment, 8 1M can be added. The port is added to the aggregation group, and the port can be directly added to a 10M port. This embodiment does not limit this.

In this embodiment, when the traffic adjustment side policy is configured, the traffic adjustment policy may be configured based on the consideration of satisfying the maximum bandwidth of the access side. At this time, the traffic adjustment policy includes a bandwidth protection policy, where the bandwidth protection policy is used to ensure The aggregation group bandwidth meets the maximum bandwidth requirement of the access side. At this time, the traffic parameter information in S102 includes: the maximum bandwidth change amount information on the access side; in S103, determining the aggregation group bandwidth adjustment requirement according to the traffic parameter information and the traffic adjustment policy includes: when the maximum bandwidth change amount information is positive The aggregation group bandwidth adjustment requirement is to increase the bandwidth, and the increase amount is greater than or equal to the maximum bandwidth change amount information; when the maximum bandwidth change amount information is negative, the aggregation group bandwidth adjustment requirement is to reduce the bandwidth, and the decrease amount is less than or equal to the maximum bandwidth change amount. The absolute value of the information.

The maximum bandwidth change amount information may be the difference between the current maximum bandwidth and the maximum bandwidth when the latest adjustment is performed. When the difference is positive, the maximum bandwidth of the access side increases, and the aggregation group needs to increase the bandwidth accordingly. The bandwidth of the adjusted aggregation group is not lower than the maximum bandwidth of the access side. Similarly, when the difference is negative, the maximum bandwidth of the access side is reduced. In this case, to save bandwidth resources and port resources, the aggregation group is used. The bandwidth can be reduced accordingly, that is, the number of member ports is reduced. However, in order to meet the bandwidth requirement of the access side, the adjusted bandwidth still needs to be no less than the maximum bandwidth of the access side. Therefore, the bandwidth reduction of the aggregation group needs to meet the above requirements. Related conditions: The reduction is less than or equal to the absolute value of the maximum bandwidth variation information.

In this embodiment, when the traffic adjustment side policy is configured, the traffic adjustment policy may be configured according to the actual traffic of the access side based on the consideration of saving the port resources. At this time, the traffic adjustment policy includes a resource utilization policy, and the resource is used. The policy is used to ensure that the bandwidth of the aggregation group meets the protection multiple of the actual traffic on the access side. The protection multiple can be set according to the actual needs, for example, it is set to 2 times, 3 times, etc., which is not limited in this embodiment. In practice, it is more common to set the protection factor to 2 times.

Further, the protection multiple may also be determined by combining the traffic peak value of the access side in a certain period of time. For example, the current peak of the actual traffic on the access side is 12M in the previous day, and the number of times the peak occurs. More, the duration is longer. It can be inferred that the current actual traffic on the access side will peak to a large extent in the future. If the adjusted aggregation group bandwidth is lower than the peak value, it is likely to cause data stream loss, etc. The error occurs and eventually brings losses to the user. Based on this consideration, the setting of the protection multiple of the present embodiment may be determined by the peak value of the traffic frequently occurring in the most recent period and the current actual traffic value. For example, current access The actual traffic is 8M. To ensure that the bandwidth of the aggregation group can meet the peak traffic demand on the access side, set the protection multiplier to a value not lower than 12/8=1.5.

In addition, the protection multiple of the embodiment may be obtained according to other data, as long as the bandwidth of the aggregation group corresponding to the protection multiple is satisfied, and the transmission data of the access side is not required to be lost.

The resource utilization policy is used to ensure that the aggregation group bandwidth meets the protection multiple of the actual traffic on the access side; the traffic parameter information includes: actual traffic change amount information. The S103 determines the bandwidth adjustment requirement of the aggregation group according to the traffic parameter information and the traffic adjustment policy. When the actual traffic change amount information is positive, the bandwidth adjustment requirement of the aggregation group is increased bandwidth, and the increase amount is greater than or equal to the actual traffic change amount information and protection. The product of the multiples; when the actual flow change amount information is negative, the bandwidth adjustment requirement of the aggregation group is to reduce the bandwidth, and the decrease amount is less than or equal to the product of the absolute value of the actual flow change amount information and the protection multiple.

The current traffic change information reflects the current actual traffic change. The change must have a reference object. Considering that the adjustment of the bandwidth of the aggregation group is based on the bandwidth of the latest adjusted aggregation group, the actual traffic change information is obtained. It is reasonable to define the difference between the current actual traffic and the actual traffic when the aggregation group bandwidth was last adjusted.

When the difference is positive, the actual traffic on the access side increases. The aggregation group needs to increase the bandwidth to meet the bandwidth requirement of the access side. Similarly, when the difference is negative, the actual traffic on the access side decreases. In this case, in order to save bandwidth resources and port resources, the aggregation group can reduce the bandwidth accordingly, that is, reduce the number of member ports. It is to be noted that, in the last time, after the bandwidth of the aggregation group is adjusted, the bandwidth of the aggregation group at the time is required to meet the bandwidth of the access side. Therefore, in this embodiment, when the bandwidth of the aggregation group is currently adjusted, Only the correspondence between the bandwidth change amount of the aggregation group and the current traffic change amount information may be considered.

For example, when the actual traffic change is +4M, the current traffic on the access side is increased by 4M compared to the actual traffic on the previous aggregation group. In this case, the bandwidth of the aggregation group needs to be increased. 4M traffic transmission. Therefore, when the resource utilization policy ensures that the bandwidth of the aggregation group meets the protection ratio of the actual traffic on the access side, the bandwidth of the aggregation group can be increased according to the protection multiple and 4M. If the protection multiple is doubled, the aggregation group is used. The bandwidth adjustment requirement is that the increase of the bandwidth of the aggregation group is not less than 8M.

For example, when the actual traffic change is -4M, the current traffic on the access side is reduced by 4M compared to the actual traffic on the previous aggregation group. In this case, the bandwidth of the aggregation group needs to meet the actual traffic. Transmission. Therefore, when the resource utilization policy ensures that the bandwidth of the aggregation group meets the protection multiple of the actual traffic on the access side, the bandwidth reduction of the aggregation group needs to exceed the value obtained by multiplying the protection multiplier by the actual traffic change amount. If the protection ratio is doubled, the bandwidth adjustment requirement of the aggregation group is that the bandwidth reduction of the aggregation group does not exceed 8M.

In addition, in the embodiment, when the process adjustment policy is a resource utilization policy, if the aggregation group is adjusted last time, the bandwidth of the aggregation group is matched with the protection ratio of the actual traffic on the access side according to the resource utilization policy. The traffic parameter information may also include the current actual traffic on the access side, and the bandwidth value to be met by the current aggregation group bandwidth is calculated according to the protection multiple. For example, the current actual traffic on the access side is 5M, and the protection multiple is 2 times. The aggregation group bandwidth needs to be at least 10M, but the bandwidth of the previous aggregation group is 8M. Therefore, the bandwidth adjustment requirement of the aggregation group is to increase the bandwidth by at least 2M.

Referring to FIG. 2, FIG. 2 shows a schematic diagram of accessing an aggregation group on the aggregation side. In the figure, DUT1 and DUT2 are core switching devices, and physical ports in the middle are all connected by physical links. For convenience of description, FIG. 2 All the lines are 1G bandwidth links, and the physical state meets the requirements of joining the aggregation group. However, the 1G bandwidth is not to be understood as a limitation on the port bandwidth. The bandwidth of the port in this embodiment is not limited, and may be 10M, 100M, or the like. In this embodiment, the small-grain multi-connection flexible extension of the physical channel is implemented, and the aggregation group is adapted.

In Fig. 2, the lines corresponding to a1, a2, a3, ..., and c1, c2, c3, ..., can be understood as links for data transmission on the access side, corresponding to the access side. The ports corresponding to b1, b2, b3, ... in Figure 2 can be understood as the physical link on the aggregation side, corresponding to multiple physical ports provided by DUT1 and DTU2 on the aggregation side, where b1, b2 The physical state of the corresponding physical port of b3····· is consistent with the requirements of joining the aggregation group.

When the access side is connected to the aggregation side, the aggregation group makes a decision, and the aggregation port is added to the aggregation group. The idle port that satisfies the aggregation condition is the port corresponding to the thick line in b1, b2, b3, . . . The member port of the aggregation group is the port corresponding to the dotted line.

The following example shows how to dynamically adjust the number of member ports in an aggregation group when the traffic policy is a bandwidth protection policy.

The maximum bandwidth of the access side on the left side of FIG. 2 is 4G, and the port on the access side is the port corresponding to lines a1, a2, a3, and a4. At this time, four 1G member ports are added to the aggregation group, and the thick line b1 is added. The ports of DTU1 corresponding to b2, b3, and b4 realize the requirement of completely satisfying the peak bandwidth usage without loss. When the access bandwidth of the access side changes, for example, the access side is connected to two new ports, the access side ports corresponding to lines a5 and a6, and the maximum access bandwidth becomes 6G, the aggregation group needs to Select two of the available ports that are free to be added as member ports to achieve real-time bandwidth expansion. In Figure 2, the ports of DUT1 corresponding to the dotted lines b5 and b6 are selected. At this time, the bandwidth of the aggregation group becomes 6G, which is not lower than the access. The maximum bandwidth of the side.

The following example shows how to dynamically adjust the member end of an aggregation group when the traffic adjustment policy is a resource utilization policy. Number of mouths.

The maximum bandwidth of the access side on the right side of Figure 2 is 4G, but the real-time traffic of the aggregation group is only 800M. In this case, if the bandwidth of the aggregation group is not less than 1.6M, the aggregation group can be configured. Just join the 2 member ports, b7, b8 correspond to the DTU2 port. When the real-time traffic on the access side changes, for example, the access side is connected to two new ports, or the traffic of the original port is increased. The real-time traffic in the aggregation group is expanded to 1.2G, and the bandwidth is expanded by 0.4G. The bandwidth increase of the group needs to be no less than 0.8M. In this case, the port of the DTU2 corresponding to b9 is added as a member port to realize the bandwidth of the aggregation group to 2.4G in real time.

In addition, the traffic adjustment policy of this embodiment may further include a threshold policy and a traffic expectation policy.

The threshold policy is used to ensure that the actual traffic on the access side does not exceed the set threshold. At this time, the traffic parameter information includes the current actual traffic on the access side. The S103 determines the bandwidth adjustment requirement of the aggregation group according to the traffic parameter information and the traffic adjustment policy. When the actual traffic on the access side exceeds the threshold, the bandwidth adjustment requirement of the aggregation group is increased, and the idle port that meets the requirements of the aggregation group is added. In the aggregation group, when the actual traffic on the access side falls from the threshold to the threshold, the previously added port can be deleted and restored to the idle port to provide services for the service or other services.

The threshold value may be set to be the maximum bandwidth of the access side, or the protection multiple of the average of the access side traffic within a certain actual range. The bandwidth added during the bandwidth adjustment of the aggregation group is not lower than the part where the actual traffic on the access side exceeds the threshold.

The traffic expectation policy is used to ensure that the bandwidth of the aggregation group meets the traffic demand of the access side bandwidth. The aggregation group can record the historical traffic of the access side, that is, the traffic of a certain historical time on the access side. For historical traffic reliability, the general historical time. The closer to the current time, the better. When the traffic on the access side is steadily increasing according to the historical traffic, it can be estimated that the traffic on the access side may also increase in a certain period of time in the future, which increases the bandwidth of the aggregation group in advance and adapts to possible future changes.

Further, when the traffic adjustment policy is configured only according to the actual traffic on the access side, if the actual traffic change amount information obtained is a negative number, the aggregation group bandwidth needs to be reduced. However, if the historical traffic on the access side is found to have a steady growth trend, the actual traffic on the access side may be contingent. The actual traffic on the access side may be in the future. It will return to the previous level and continue to grow. At this time, it is obviously inappropriate to reduce the bandwidth of the aggregation group based on the actual traffic change information, which cannot meet the growth trend of the future traffic of the access side.

When the traffic adjustment policy is configured based on the maximum bandwidth of the access side, the bandwidth of the general aggregation group must be met. The maximum bandwidth requirement. At this time, if the historical traffic information is found, the historical traffic on the access side does not exceed a certain fixed value, and the historical traffic on the access side may decrease or may fluctuate up and down within a certain range. Generally, the traffic on the access side may not exceed the fixed value in a certain period of time. When the difference between the fixed value and the maximum bandwidth is large, the bandwidth of the aggregation group is limited or not. The maximum bandwidth obviously causes the bandwidth of the aggregation group to be wasted, which is not conducive to improving the utilization of the port.

Therefore, in order to make the aggregation group bandwidth more flexible and more suitable, and to cope with more complex networking requirements and improve port utilization, this embodiment also provides a more complex traffic adjustment strategy: comprehensive consideration strategy, comprehensive The policy considers that the bandwidth of the aggregation group meets the calculation value of the preset function established by the historical traffic, the actual traffic, and the maximum bandwidth on the access side; the traffic parameter information includes: actual traffic information and maximum bandwidth information; and is determined according to the traffic parameter information and the traffic adjustment policy. The bandwidth adjustment requirement of the aggregation group includes: determining the bandwidth adjustment requirement of the aggregation group according to the actual traffic information, the maximum bandwidth information, and the traffic adjustment policy.

The following figure illustrates the process of determining the calculated value of the preset function. If the historical traffic on the access side is the historical traffic of the first 3 days of the current time, the historical traffic is always floating between 5M and 8M, and the maximum bandwidth on the access side is 15M. The current actual traffic on the access side is 7M. It can be foreseen that the actual traffic on the access side may not exceed 8M in the future. The default function calculation value is not less than 8M, or it can be set at 8M. Between 15M, if it is in historical traffic, the peak value of traffic has reached 9M, and the number of peak occurrences is large. In order to meet the peak traffic, the data on the access side has no loss requirement, and the calculated function value can be set to be low. For the value of 9M, in the consideration of saving port resources, the calculation value of the prediction function can be set to a value between 9M and 15M.

Further, in this embodiment, a plurality of physical link domains are separated on the aggregation side, and each physical link domain is configured with one aggregation group. The number of member ports in the aggregation group is dynamically adjusted according to the bandwidth requirement of the aggregation group. The aggregation group bandwidth requirement dynamically adjusts the number of member ports in the aggregation group in the physical link domain corresponding to the aggregation group. The aggregation group bandwidth requirement here can be determined in the manner described above in the embodiment.

It is foreseen that when the aggregation side needs to be isolated by multiple physical channels, the configuration of the aggregation group is the best choice. In this embodiment, the configuration on the aggregation side is very simple and easy to maintain. When the traffic on the access side changes, The aggregation group can be automatically expanded and contracted without additional configuration, so as to fully utilize the port resources on the aggregation side.

The dynamic link aggregation implementation method of the embodiment may be configured to configure a traffic adjustment policy, obtain traffic parameter information of the current access side, determine a bandwidth adjustment requirement of the aggregation group according to the traffic adjustment policy and the traffic parameter information, and then adjust the aggregation group according to the requirement. The number of member ports. In this embodiment, the adjustment of the member port needs to consider the current connection. The traffic parameter information on the inbound side is more suitable for the current transmission needs of the access side. Compared with the prior art, the method determines whether the aggregation group needs to be added to the aggregation group according to the physical correlation attribute of the port. In this embodiment, the bandwidth adjustment requirement of the aggregation group can be flexibly determined according to the current traffic parameter information of the access side to ensure that the dynamic change of the aggregation group is satisfied. Access side requirements. Therefore, the dynamic link aggregation implementation method of the present invention has higher flexibility, can improve the utilization of the physical port, reduce the maintenance cost, simplify the networking complexity, achieve the requirement of optimizing the layout in the software, and improve the user satisfaction.
