Detailed Description
Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
It should be understood that in the description of the application, "at least one" means one or more than one, and "a plurality" means two or more than two. In addition, the words "first," "second," and the like, unless otherwise indicated, are used solely for the purposes of description and are not to be construed as indicating or implying a relative importance or order.
Fig. 1 is a flow chart of a method for allocating bus bandwidth resources according to an embodiment of the present application. As shown in fig. 1, the method includes the following steps.
Step S110: a first port and a plurality of devices hooked under the first port are determined.
Step S120: determining a port level maximum allowed bandwidth resource for the first port, and determining a device level minimum required bandwidth resource and a device level maximum allowed bandwidth resource for each of the plurality of devices.
Step S130: dividing the plurality of devices into at least two groups.
Wherein each of the at least two groups belongs to one of a plurality of group categories, each of the plurality of group categories having a group level maximum allowed bandwidth resource and a group level bandwidth resource allocation policy, a sum of the group level maximum allowed bandwidth resources of each of the at least two groups not exceeding a port level maximum allowed bandwidth resource of the first port, a sum of the device level maximum allowed bandwidth resources of the devices included in each of the at least two groups not exceeding the group level maximum allowed bandwidth resources of the group. The plurality of group categories comprise a first group category, a second group category, a third group category and a fourth group category, wherein the group-level bandwidth resource allocation policy of the first group category allocates bandwidth resources according to minimum required bandwidth resources of a device level, the group-level bandwidth resource allocation policy of the second group category allocates bandwidth resources through competition, the group-level bandwidth resource allocation policy of the third group category allocates bandwidth resources according to a combination of minimum required bandwidth resources and bandwidth resources through competition, and the group-level bandwidth resource allocation policy of the fourth group category allocates bandwidth resources according to maximum allowed bandwidth resources of the device level. The at least two groups include a first group and a second group, the first group belonging to the first group category, the second group belonging to the second group category, the third group category, or the fourth group category.
Referring to fig. 1, a first port and a plurality of devices hooked under the first port are determined at step S110. As such, any bus standard may be adapted, such as the peripheral component interconnect (PERIPHERAL COMPONENT INTERCONNECT, PCI) bus standard or the peripheral component interconnect express (PERIPHERAL COMPONENT INTERCONNECT EXPRESS, PCIe) bus standard. In general, the PCI bus is a tree structure and is independent of the CPU bus and is operable in parallel with the CPU bus. PCI equipment and PCI bridge pieces can be hung on a PCI bus, only one PCI master equipment is allowed on the PCI bus, the other PCI slave equipment is all available, and the read-write operation can only be carried out between the master equipment and the slave equipment, and the data exchange between the slave equipment needs to be transferred through the master equipment. PCIe bus is a layered protocol consisting of a transaction layer, a data link layer, and a physical layer. Through a data processing unit or a virtualization technology, a plurality of standard PCIe devices of different types can be simulated for the host machine, and the whole PCIe topology structure can be simulated, so that an operating system of the host machine enumerates the PCIe topology structure and the PCIe devices, and further driving is realized. PCIe topology and PCIe devices are hooked under a certain port. Thus, the first port is determined in step S110, and the plurality of devices hooked under the first port are all devices performing bus operations through the first port. The first port may be a port in a PCI bus, a PCIe bus, or any other suitable bus.
With continued reference to fig. 1, in step S120, a port level maximum allowed bandwidth resource of the first port is determined, and a device level minimum required bandwidth resource and a device level maximum allowed bandwidth resource of each of the plurality of devices are determined. In this way, on the basis of determining the first port and the plurality of devices that are hooked under the first port, bandwidth resource allocation information of a port level, that is, a port level maximum allowed bandwidth resource of the first port, may be determined. Here, the maximum allowed bandwidth resource at the port level of the first port represents the highest bandwidth resource that can be occupied by all devices that perform bus operations (e.g., process upstream and downstream traffic, issue interrupts, etc.) through the first port. In other words, regardless of how the PCIe topology hooked under the first port changes, how devices hooked under the first port add, delete, or change is limited by port-level bandwidth resource allocation information. In addition, bandwidth resource allocation information of a device level, that is, a minimum required bandwidth resource of a device level and a maximum allowed bandwidth resource of a device level of each of the plurality of devices is also determined at step S120. Here, the minimum bandwidth resource required at the device level of each of the plurality of devices represents the minimum bandwidth resource required for the devices to operate normally, and may be set according to factory settings, product specifications, and application scenarios. For example, the minimum required bandwidth resource at the device level of a certain network card device may be 100 Megabytes (MB). The maximum allowable bandwidth resources at the device level for each of the plurality of devices represents the highest bandwidth resources that the devices can occupy and may be set according to device performance and design constraints. For example, the minimum required bandwidth resource at the device level of a certain network card device may be 100 Megabytes (MB), while the maximum allowed bandwidth resource at the device level of the network card device may be 1 Gigabyte (GB).
With continued reference to fig. 1, on the basis of determining port-level bandwidth resource allocation information and device-level bandwidth resource allocation information, the group-level bandwidth resource allocation information can be set in combination with user requirements, application scenarios and the like, so that bandwidth resource allocation requirements under different device scales, user requirements and application scenarios can be flexibly adapted. At step S130, the plurality of devices are partitioned into at least two groups. Here, each of the at least two groups belongs to one of a plurality of group categories, each of the plurality of group categories has a group-level maximum allowed bandwidth resource and a group-level bandwidth resource allocation policy, a sum of the group-level maximum allowed bandwidth resources of each of the at least two groups does not exceed a port-level maximum allowed bandwidth resource of the first port, and a sum of the device-level maximum allowed bandwidth resources of the devices included in each of the at least two groups does not exceed the group-level maximum allowed bandwidth resource of the group. Thus, by means of a plurality of group categories, different group-level maximum allowed bandwidth resources and group-level bandwidth resource allocation policies are provided, such that by dividing the plurality of devices into the at least two groups, a specific group category and corresponding group-level maximum allowed bandwidth resources and group-level bandwidth resource allocation policies can be corresponded. By defining that the sum of the maximum allowed bandwidth resources of the group level of each of the at least two groups does not exceed the maximum allowed bandwidth resources of the port level of the first port, and defining that the sum of the maximum allowed bandwidth resources of the device level of the device included in each of the at least two groups does not exceed the maximum allowed bandwidth resources of the group level of the group, a three-level structure comprising the bandwidth resource allocation information of the port level, the bandwidth resource allocation information of the group level and the bandwidth resource allocation information of the device level is established at the global level, the limitation of upper-layer business on the related allocable bandwidth resources of the first port can be met, and therefore, the bandwidth resources occupied by the device under the first port during the startup and the initialization of the system and the operation process of the system are not exceeded the maximum allowed bandwidth resources of the port level of the first port can be ensured, and the business stability is improved. In addition, by establishing the bandwidth resource allocation information of the group level, as an intermediate layer between the bandwidth resource allocation information of the port level and the bandwidth resource allocation information of the device level, the minimum bandwidth resource required by the device level to ensure normal operation, that is, the minimum required bandwidth resource of the device level of each of the plurality of devices, can be satisfied on the premise of ensuring that the limitation of the upper layer service on the maximum allowed bandwidth resource of the port level of the first port is satisfied. The following is a detailed description.
With continued reference to fig. 1, the plurality of group categories includes a first group category, a second group category, a third group category, and a fourth group category. The bandwidth resources of the first group class are allocated according to minimum required bandwidth resources of the device class, the bandwidth resources of the second group class are allocated by competition, the bandwidth resources of the third group class are allocated according to the combination of minimum required bandwidth resources and bandwidth resources allocated by competition, and the bandwidth resources of the fourth group class are allocated according to maximum allowed bandwidth resources of the device class. Thus, by setting the group level bandwidth resource allocation policy for each of the plurality of group categories, the complex and variable bandwidth resource allocation needs can be flexibly adapted. Wherein the group level bandwidth resource allocation policy of the first group class allocates bandwidth resources according to the device level minimum required bandwidth resources, which means that the bandwidth resources allocated to the devices belonging to the group of the first group class are allocated according to the device level minimum required bandwidth resources of the respective devices. For example, the minimum required bandwidth resource at the device level of a certain network card device may be 100 megabytes, and if the network card device is divided into groups belonging to the first group category, the bandwidth resource occupied by the network card device is 100 megabytes. In this way, by the group level bandwidth resource allocation policy of the first group class, it is possible to ensure that the minimum bandwidth resource required by the device level to ensure normal operation, that is, the minimum required bandwidth resource at the device level of each of the plurality of devices, is satisfied. The group level bandwidth resource allocation policy of the second group class allocates bandwidth resources by contention, which means that the bandwidth resources allocated to devices belonging to the group of the second group class are allocated as a result of contention allocation by the respective devices, and some devices may have a faster speed such as remote direct memory access devices and thus may occupy most or all of the allocatable bandwidth resources. Therefore, the performance of the equipment can be fully exerted through the group-level bandwidth resource allocation strategy of the second group category, so that the equipment with higher speed can occupy more bandwidth resources, and the utilization rate of the bandwidth resources can be improved. The group level bandwidth resource allocation policy of the third group category is a combination of allocating bandwidth resources according to minimum required bandwidth resources and allocating bandwidth resources by contention, which means that the bandwidth resources allocated to the devices in the group of the third group category are allocated in part according to the minimum required bandwidth resources and in part according to the result of the contention allocation of the respective devices. For example, the minimum required bandwidth resource at the device level of a certain network card device may be 100 megabytes, and if the network card device is divided into groups belonging to the third group category, the bandwidth resource occupied by the network card device is 100 megabytes plus the result of competing allocation of the network card device with other devices in the same group. Therefore, through the group-level bandwidth resource allocation strategy of the third group category, the performance of the device can be fully exerted and the bandwidth resource utilization rate can be improved on the basis of ensuring that the minimum bandwidth resource required by the device level for ensuring normal operation, namely the minimum required bandwidth resource of the device level of each of the plurality of devices is met. The group level bandwidth resource allocation policy of the fourth group class is to allocate bandwidth resources according to the maximum allowed bandwidth resources of the device level, which means that the devices in the group of the fourth group class are allocated bandwidth resources according to the maximum allowed bandwidth resources of the device level of each device, which means that each device can occupy the highest bandwidth resources that it is allowed to occupy. Therefore, the performance of the equipment can be exerted to the maximum extent through the group-level bandwidth resource allocation strategy of the fourth group category, and the competition conflict among the equipment is avoided through the maximum allowed bandwidth resources of the equipment levels allocated to the equipment, so that the allocated bandwidth resources of different equipment are ensured to be independent. It can be seen that the group level bandwidth resource allocation policy is from the minimum required bandwidth resource allocation bandwidth resource according to the device level, to the bandwidth resource allocation by contention, to the combination of the bandwidth resource allocation according to the minimum required bandwidth resource and the bandwidth resource allocation by contention, and finally to the maximum allowed bandwidth resource allocation bandwidth resource according to the device level, from the first group category to the second group category to the third group category to the fourth group category. Therefore, by setting the group level bandwidth resource allocation policy for each of the plurality of group categories, on the premise of ensuring that the limitation of the upper layer service on the maximum allowed bandwidth resource of the port level of the first port is met, the minimum bandwidth resource required by the device level for ensuring normal operation, that is, the minimum bandwidth resource required by the device level of each of the plurality of devices, is also met, and by dividing a device into groups belonging to a specific group category, the self performance of the device can be controlled to be exerted to the greatest extent, and whether independent bandwidth resources are provided for the device can be selected, so that the flexible adaptation of the bandwidth resource allocation needs with complex and variable requirements is facilitated. For example, when a particular device is partitioned to determine the groups in which the particular device is located, the group-level bandwidth resource allocation policy for each group and the priority of user demand may be combined. For users with lower priority demands, such as users of virtual storage devices like virtual hard disks, the virtual storage devices have a low probability of being required to initiate storage operation requests at the same time, so that only a part of the virtual storage devices generally need to utilize bandwidth resources for data reading and writing at the same time, so that the virtual storage devices can be divided into groups belonging to a second group category, bandwidth resources are allocated by competition, and the maximum allowable bandwidth resources at the group level can be fully utilized. For higher priority users, such as users of storage devices for data centers, games, video, who have high latency requirements and want stable data transmission performance, i.e. the fluctuation of bandwidth resources is as small as possible, so that these storage devices can be divided into groups belonging to the fourth group category, and bandwidth resources are allocated according to the maximum allowable bandwidth resources at the device level, so that it can be ensured that the allocated bandwidth resources of these storage devices are independent of each other, thus reducing the fluctuation of bandwidth resources, which is beneficial to ensuring satisfaction of latency requirements and stability requirements of data transmission performance.
With continued reference to fig. 1, on the basis of determining port-level bandwidth resource allocation information and device-level bandwidth resource allocation information, and on the basis of flexibly adapting to complex and diverse bandwidth resource allocation needs by setting group-level bandwidth resource allocation information, by defining the at least two groups to include a first group belonging to the first group category and a second group belonging to the second group category, the third group category or the fourth group category. By establishing the bandwidth resource allocation information of the group level as an intermediate hierarchy between the bandwidth resource allocation information of the port level and the bandwidth resource allocation information of the device level, the minimum bandwidth resource required by the device level to ensure normal operation, that is, the minimum required bandwidth resource of the device level of each of the plurality of devices, can be satisfied on the premise of ensuring that the limitation of the upper layer service on the maximum allowed bandwidth resource of the port level of the first port is satisfied. The first group belongs to the first group category, the second group belongs to the second group category, the third group category or the fourth group category, so that a hierarchical group level bandwidth resource allocation strategy of the at least two groups is established, and the maximum allowed bandwidth resources of the at least two groups are combined, so that a three-level structure comprising port level bandwidth resource allocation information, group level bandwidth resource allocation information and device level bandwidth resource allocation information is established on a global level, and the limitation of upper layer business on the related allocable bandwidth resources of the first port can be met, and therefore, the bandwidth resources occupied by equipment under the first port can not exceed the maximum allowed bandwidth resources of the port level of the first port during the system operation process, and the business stability is improved.
In summary, the method for bus bandwidth resource allocation shown in fig. 1 establishes a three-level structure including port-level bandwidth resource allocation information, group-level bandwidth resource allocation information and device-level bandwidth resource allocation information on a global level, thereby implementing the limitation of meeting the upper layer service on the first port-related allocable bandwidth resources, ensuring that the bandwidth resources occupied by devices under the first port do not exceed the maximum allowed bandwidth resources of the port level of the first port when the system is on-line and initialized and in the running process of the system, and improving the service stability; and, by establishing the bandwidth resource allocation information at the group level, as an intermediate hierarchy between the bandwidth resource allocation information at the port level and the bandwidth resource allocation information at the device level, not only the minimum bandwidth resource required by the device level in order to ensure normal operation, that is, the minimum bandwidth resource required at the device level of each of the plurality of devices, but also how much to exert the self-performance of the device by dividing a specific device into groups belonging to the specific group category can be controlled, and whether to provide independent bandwidth resources for the device can be selected, which is helpful for flexibly adapting to the complex and variable bandwidth resource allocation needs and adapting to the increasing device scale.
Fig. 2 is a schematic diagram of a shortcut peripheral device interconnection topology according to an embodiment of the present application. As shown in fig. 2, the plurality of devices that are hooked under the port 202 are divided into three groups. The three groups are group A210, group B220, and group C230, respectively. The devices in group a210 include a storage device a211, a graphics processor a212, a storage device B213, and a network device E214. The devices in group B220 include graphics processor B221, remote direct memory access device 222, network device F223, storage device C224. The devices in group C230 include network device a231, network device B232, network device C233, and network device D234. It can be seen that the devices in the same group may be of the same type, may be of different types, may be of the same system or may be of different systems. Referring to the method for bus bandwidth resource allocation shown in fig. 1 above, the sum of the group level maximum allowed bandwidth resources of each of the at least two groups does not exceed the port level maximum allowed bandwidth resources of the first port. Thus, the sum of the group level maximum allowed bandwidth resources for each of group a210, group B220, and group C230 does not exceed the port level maximum allowed bandwidth resources for port 202. This ensures that regardless of changes in at least two groups that are hooked under the port 202, such as changes in PCIe topology, devices that are hooked under the port 202 are limited by port-level bandwidth resource allocation information. In addition, the sum of the device-level maximum allowable bandwidth resources of the devices included in each of the at least two groups does not exceed the group-level maximum allowable bandwidth resources of the group, and thus, the sum of the device-level maximum allowable bandwidth resources of the devices included in each of the group a210, the group B220, and the group C230 does not exceed the group-level maximum allowable bandwidth resources of the group. For example, the devices in group C230, i.e., network device a231, network device B232, network device C233, and network device D234 each have a device level maximum allowable bandwidth resource that does not exceed the sum of the maximum allowable bandwidth resources of group C230.
With continued reference to fig. 2, the group-level bandwidth resource allocation policy is from minimum required bandwidth resources allocation bandwidth resources according to the device level, to bandwidth resources allocation by contention, to bandwidth resources allocation by combination of minimum required bandwidth resources and bandwidth resources allocation by contention, and finally to bandwidth resources allocation by maximum allowed bandwidth resources at the device level, so that devices are bandwidth resources that are allowed to exert their own performance to a greater degree and also have higher independence, in order from the first group class to the fourth group class. In some embodiments, the group level maximum allowed bandwidth resources are incremented in order from the first group category to the fourth group category. For example, let port 202 have a port level maximum allowed bandwidth resource of 100 gigabytes, where group A210 belongs to a first group class and group A210 has a group level maximum allowed bandwidth resource of 10 gigabytes, group B220 belongs to a second group class and group B220 has a group level maximum allowed bandwidth resource of 30 gigabytes, group C230 belongs to a fourth group class and group C230 has a group level maximum allowed bandwidth resource of 60 gigabytes. Thus, under the design purpose of maximizing bandwidth resource utilization, the maximum bandwidth of an upper-layer service adaptation port and the bandwidth resource allocation requirement of the lower-layer equipment can be fully met by flexibly adjusting the allocated actual bandwidth resource of each equipment or enabling the equipment to self-contend for the bandwidth resource or combining the two, and dividing each equipment into a specific group with a specific group-level maximum allowable bandwidth resource and a specific group-level bandwidth resource allocation strategy at a more macroscopic level.
Referring to fig. 1 and 2, in one possible implementation, dividing the plurality of devices into the at least two groups includes:
dividing the plurality of devices into the at least two groups based on respective bandwidth allocation priorities of the plurality of devices and respective group-level bandwidth resource allocation policies of the at least two groups. The group level bandwidth resource allocation policy is from minimum required bandwidth resources allocation bandwidth resources according to device level, to bandwidth resources allocation by contention, to bandwidth resources allocation by combination of minimum required bandwidth resources allocation bandwidth resources and bandwidth resources allocation by contention, and finally to bandwidth resources allocation by maximum allowed bandwidth resources according to device level, so that devices are bandwidth resources which are allowed to exert their own performance to a greater degree and also have higher independence in the order from the first group class to the fourth group class. Thus, based on the bandwidth allocation priority of a device, it can be determined how much self-performance the device is allowed to exert and how highly independent bandwidth resources are provided. In this way, the devices with higher bandwidth allocation priorities can be divided into the groups belonging to the fourth group category by combining the bandwidth allocation priorities of the devices and the group-level bandwidth resource allocation policies of the at least two groups, so that bandwidth resources are allocated according to the maximum allowable bandwidth resources of the device level, the performance of the devices can be exerted to the maximum extent, and the independence of the allocated bandwidth resources of the devices can be ensured. In addition, the devices with lower bandwidth allocation priority can be divided into groups belonging to the first group category, so that bandwidth resources are allocated according to minimum required bandwidth resources of the device level, thus ensuring that the minimum bandwidth resources required by the device level in order to ensure normal operation, namely the minimum required bandwidth resources of the device levels of the devices, can provide more bandwidth resources for the devices with higher bandwidth allocation priority under the condition of limited maximum allowed bandwidth resources of the port level, and can better match the bandwidth allocation priority of each device. As such, flexible adaptation to complex and diverse bandwidth resource allocation needs is facilitated as well as to an increasing device size.
In some embodiments, the plurality of devices includes a first device that is partitioned into the first group when the bandwidth allocation priority of the first device is a low bandwidth allocation priority, and is partitioned into the second group when the bandwidth allocation priority of the first device is a high bandwidth allocation priority. In this way, the bandwidth allocation priorities of the devices and the group-level bandwidth resource allocation policies of the at least two groups are combined, and the first group belongs to the first group category and the second group belongs to the second group category, the third group category or the fourth group category, which is combined, so that the flexible adaptation of complex and changeable bandwidth resource allocation needs and the adaptation of the increasing device scale are facilitated.
In some embodiments, the bandwidth allocation priority of the first device is a low bandwidth allocation priority when the first device is a storage device for non-real time communications, and a high bandwidth allocation priority when the first device is a network device for data centers, games or video. In this manner, the group-level bandwidth resource allocation policy for each group and the priority of user demand may be integrated into consideration when partitioning a particular device to determine the group in which the particular device is located. Storage devices that communicate in non-real time typically only occupy a portion of the bandwidth resources for bus operations at the same time, and the associated user demands relatively little time scalability. Network devices for data centers, games or video often need to handle large-scale data traffic for concurrency, and the associated user demands relatively high temporal ductility. As such, flexible adaptation to complex and diverse bandwidth resource allocation needs is facilitated as well as to an increasing device size.
In a possible embodiment, the devices comprised by each of the at least two groups have the same device type or different device types. The devices in the same group may be of the same type, may be of different types, may be of the same system or may be of different systems. Thus, under the design purpose of maximizing bandwidth resource utilization, by flexibly adjusting the actual bandwidth resource allocated to each device or letting the device self-contend for the bandwidth resource, or both, and by dividing each device into a specific group with a specific group-level maximum allowable bandwidth resource and a specific group-level bandwidth resource allocation strategy at a more macroscopic level, the maximum bandwidth of an upper-layer service adaptation port and the bandwidth resource allocation requirements of the lower-layer device can be fully met.
In a possible implementation, the bandwidth resources allocated by each of the devices included in the group belonging to the second group category of the at least two groups are all obtained by competing for the group-level maximum allowed bandwidth resources of the group. Therefore, the performance of the equipment can be fully exerted through the group-level bandwidth resource allocation strategy of the second group category, so that the equipment with higher speed can occupy more bandwidth resources, and the utilization rate of the bandwidth resources can be improved.
In a possible implementation, the bandwidth resources each allocated by a device comprised by a group belonging to the third group category of the at least two groups comprises a device-level minimum required bandwidth resource and is obtained at least in part by competing for a group-level maximum allowed bandwidth resource of the group. Therefore, through the group-level bandwidth resource allocation strategy of the third group category, the performance of the device can be fully exerted and the bandwidth resource utilization rate can be improved on the basis of ensuring that the minimum bandwidth resource required by the device level for ensuring normal operation, namely the minimum required bandwidth resource of the device level of each of the plurality of devices is met.
In one possible implementation, the plurality of devices includes a second device that is partitioned into a third group of the at least two groups based on a bandwidth allocation priority of the second device, the method further comprising: and transferring the second device from the third group to a fourth group of the at least two groups based on the bandwidth usage degree of the second device, and reallocating bandwidth resources to the second device according to a group-level maximum allowed bandwidth resource and a group-level bandwidth resource allocation policy of the fourth group, wherein the group category of the fourth group is different from the group category of the third group. As mentioned above, the plurality of devices are partitioned into the at least two groups based on their respective bandwidth allocation priorities and their respective group-level bandwidth resource allocation policies. Thus, devices are bandwidth resources that are allowed to exert their own performance to a greater degree and also have a higher independence, in order from the first group category to the fourth group category. Based on the bandwidth allocation priority of a device, it can be determined how much self-performance the device is allowed to perform and how highly independent bandwidth resources are provided. Here, an adjustment may be made to a previous division result based on a bandwidth usage degree of the second device, the second device is transferred from the third group to a fourth group of the at least two groups, and bandwidth resources are reallocated to the second device according to a group-level maximum allowable bandwidth resource and a group-level bandwidth resource allocation policy of the fourth group. And, the group class to which the fourth group belongs is different from the group class to which the third group belongs, which means that the group-level bandwidth resource allocation policies of different group classes are sequentially applicable to the second device. Thus, the method is beneficial to improving the utilization rate of the whole bandwidth resources by combining the actual application condition of the bandwidth resources of the equipment.
In some embodiments, the first group category, the second group category, the third group category, and the fourth group category are ranked by group level priority from low to high, the group level priority of the group category to which the fourth group belongs being higher than the group level priority of the group category to which the third group belongs when the bandwidth usage level of the second device is above a first threshold, and the group level priority of the group category to which the fourth group belongs being lower than the group level priority of the group category to which the third group belongs when the bandwidth usage level of the second device is below a second threshold. Thus, the method is beneficial to improving the utilization rate of the whole bandwidth resources by combining the actual application condition of the bandwidth resources of the equipment.
In some embodiments, the bandwidth usage degree of the second device is a bandwidth resource utilization rate of the second device in a specified period of time, or a transceiving traffic of the second device in the specified period of time. Thus, the method is beneficial to improving the utilization rate of the whole bandwidth resources by combining the actual application condition of the bandwidth resources of the equipment.
In one possible implementation, the device types of each of the plurality of devices include: storage device type, network device type, remote direct memory access device type, central processor device type, graphics processor device type. Therefore, the maximum bandwidth of the upper layer service adaptation port and the bandwidth resource allocation requirement of the lower layer equipment can be fully met.
In one possible embodiment, the plurality of devices includes at least one physical device or at least one virtual device, the at least one virtual device being generated by the data processing unit simulation. Therefore, the maximum bandwidth of the upper layer service adaptation port and the bandwidth resource allocation requirement of the lower layer equipment can be fully met. It should be appreciated that the virtual device may be provided by the data processing unit or any suitable virtualization technique, or may be hooked up to a physical device that is actually present, such as a slot of a board card inserted into the data processing unit.
In one possible implementation, the first port belongs to a first bus, which is a peripheral device interconnect bus, a fast peripheral device interconnect bus, an advanced extensible interface bus (Advanced eXtensible Interface, AXI) or a computer high-speed interconnect bus (Compute Express Link, CXL). Therefore, any bus standard can be adapted, and the maximum bandwidth of an upper-layer service adaptation port and the bandwidth resource allocation requirement of lower-layer equipment can be fully met.
