Description

Method and related device for adjusting switching port of forwarding processing thread

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a method and a related apparatus for adjusting a switch port of a forwarding processing thread.

Background

The virtualization technology is a decoupling technology for separating the bottom hardware device from the upper operating system and the application program, and as shown in fig. 1, a Virtual Machine Monitor (VMM) layer is introduced to manage the bottom hardware resources and create a Virtual Machine (VM) independent of the bottom hardware for the upper operating system and the application program.

Network Function Virtualization (NFV) technology can make mobile operators vary from day to day in how to build their own networks and implement new services. Through the virtualization technology, software and hardware separation is realized, and an operator can provide faster and better network service and is helped to compete with internet manufacturers. Among others, a final goal of applying NFV technology is to replace those proprietary dedicated network element devices of communication networks by x86 server, storage and switching devices based on industry standards. Therefore, network element devices such as a firewall, flow charging, routing service and the like which are operated originally can be migrated into the VM to operate in the NFV scene, so that the cost is saved, and the utilization rate of resources and the flexible control capability are improved. This puts higher demands on performance specifications such as the switching capability, packet loss rate, and delay of a Virtual Switch (vSwitch) in a virtualized scene.

In the NFV field, there is a Service chain (ServiceChain) mechanism, that is, at the edge of mobile, fixed broadband and data center networks, a specific Service flow of a specific user may need to be processed one by one through multiple Virtual Application Service (VAS) entities in sequence. For example, a service flow on a HyperText transfer protocol (HTTP) world wide Web (Web) needs to be sequentially connected with three VAS entities, namely a content filter, a cache service and a firewall, in series to perform corresponding processing, and then the processed service flow enters the Internet (Internet). In view of an operator, each user corresponds to one service package, one service package can correspond to one ServiceChain, and the content of the service package can be changed, namely, the used service or VAS sequence can be changed, so that the aim of flexible control can be achieved.

In the process of network virtualization, a service with high network throughput is transferred and operated in a VM in an NFV scenario, so that both a VM across a physical host and a VM with the physical host need high network traffic exchange capabilities, which are mainly provided by vSwitch. However, the vSwitch is responsible for network traffic switching, which may become a bottleneck if a single Central Processing Unit (CPU) is used, and therefore, the introduction of multi-core parallel Processing capability to improve network traffic switching performance of the vSwitch is considered in the industry.

Under the condition that the vSwitch uses a multi-core forwarding mechanism, multiple CPUs are used for processing at the same time, and each port (port) of each VM and an uplink port (uplink port) of a physical network card need to be handed to a certain CPU for processing, so that the processing capacity of the multiple CPUs can be utilized. Wherein each forwarding processing thread in vSwitch corresponds to a different CPU. As to which ports traffic needs to be handled by a CPU (corresponding to a forwarding processing thread), the prior art fixedly binds the CPU (corresponding to the forwarding processing thread) and the ports before the service runs, for example, CPU1 and Port1 are fixedly bound (equivalent to fixedly binding the forwarding processing thread corresponding to CPU1 and Port 1), and CPU2 and Port2 are fixedly bound (equivalent to fixedly binding the forwarding processing thread corresponding to CPU2 and Port 2). The inventor of the invention finds that in the research and practice process, the fixed binding of the forwarding processing thread and the Port in the prior art always makes the forwarding processing thread and the Port difficult to flexibly adapt to the change of network flow, and simultaneously influences the resource utilization efficiency.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for adjusting a switch port of a forwarding processing thread according to an embodiment of the present invention, where the method for adjusting a switch port of a forwarding processing thread according to an embodiment of the present invention may include:

301. the state attributes of K forwarding processing threads of a virtual switch (vSwitch) in a Host (Host) are detected.

The state attributes of the K forwarding processing threads of the vSwitch in the Host may be detected in real time or periodically, or may be detected under the trigger of some trigger conditions. The triggering condition may be, for example, a device restart, a component replacement, a virtual machine migration, or the like.

Optionally, in some possible embodiments of the present invention, the state attribute of the forwarding processing thread includes at least one of the following state attributes: the method comprises the following steps of affinity between a processor of a forwarding processing thread and an exchange port served by the processor, a residual forwarding resource limit of the forwarding processing thread, a residual forwarding resource limit proportion of the forwarding processing thread, and a forwarding resource limit actually occupied by key traffic of the exchange port served by the forwarding processing thread (namely the forwarding resource limit actually occupied by the key traffic of the exchange port served by the forwarding processing thread), wherein the service priority of the key traffic is higher than a priority threshold.

302. And under the condition that the state attributes of K forwarding processing threads of the vSwitch are detected to meet preset adjustment triggering conditions, adjusting switching ports served by at least 1 forwarding processing thread in the K forwarding processing threads, wherein K is a positive integer.

The switching ports comprise virtual switching ports and/or physical switching ports, and the virtual switching ports are connected with virtual machines running on the host machines.

Wherein a virtual machine running on the host machine may provide a VAS.

Wherein adjusting the switch ports served by at least 1 of the K forwarding processing threads may include: adding, deleting and/or changing a switch port served by at least 1 of the K forwarding processing threads.

It can be seen that, in this embodiment, by detecting the state attributes of K forwarding processing threads of a vSwitch in a host, and when detecting that the state attributes of the K forwarding processing threads of the vSwitch meet a preset adjustment trigger condition, an exchange port served by at least 1 forwarding processing thread of the K forwarding processing threads is adjusted. Due to the introduction of the mechanism capable of adjusting the switching ports served by the forwarding processing threads according to the state attributes of the forwarding processing threads of the vSwitch, the switching ports served by the forwarding processing threads can be dynamically changed, and the traditional mechanism that the forwarding processing threads and the switching ports served by the forwarding processing threads are always fixedly bound is abandoned, so that the improvement of the utilization rate of forwarding resources and the adaptive capacity of network traffic change under the virtual architecture is facilitated.

Optionally, in some possible embodiments of the present invention, the adjustment triggering condition includes at least one of the following conditions: the difference between the forwarding resource limit actually occupied by the key traffic forwarded and processed by the forwarding processing thread and the forwarding resource limit nominally occupied by the key traffic exceeds a preset range, the affinity between the processor of the forwarding processing thread and the switching port served by the processor of the forwarding processing thread is lower than the preset range, and the load balance among the K forwarding processing threads is lower than the preset range.

Optionally, in some possible embodiments of the present invention, the adjusting the switch ports served by at least 1 forwarding processing thread of the K forwarding processing threads is performed such that at least one of the following conditions is satisfied: the difference between the forwarding resource quota actually occupied by the critical traffic forwarded and processed by at least 1 forwarding processing thread of the K forwarding processing threads and the forwarding resource quota nominally occupied by the critical traffic is reduced (for example, the difference between the forwarding resource quota actually occupied by the critical traffic forwarded and processed by the forwarding processing thread and the forwarding resource quota nominally occupied by the critical traffic does not exceed a preset range), the affinity between the processor of at least 1 forwarding processing thread of the K forwarding processing threads and the switching port served by the processor of the at least 1 forwarding processing thread is improved (for example, the affinity between the processor of the forwarding processing thread and the switching port served by the processor of the forwarding processing thread is higher than the preset range), and the load balance between the K forwarding processing threads is improved (for example, the load balance between the K forwarding processing threads is higher than the preset range).

For example, assume that the adjustment trigger condition includes the following conditions: if the difference between the forwarding resource quota actually occupied by the critical traffic forwarded by the forwarding processing thread and the forwarding resource quota nominally occupied by the critical traffic exceeds a preset range, then the switching port served by at least 1 of the K forwarding processing threads is adjusted, so that the difference between the forwarding resource quota actually occupied by the critical traffic forwarded by at least 1 of the K forwarding processing threads and the forwarding resource quota nominally occupied by the critical traffic is reduced (for example, the difference between the forwarding resource quota actually occupied by the critical traffic forwarded by the forwarding processing threads and the forwarding resource quota nominally occupied by the critical traffic does not exceed the preset range).

By way of further example, assume that the adjustment trigger condition includes the following conditions: if the affinity between the processor of the forwarding processing thread and the switch port served by the processor is lower than the preset range, the switch port served by at least 1 of the K forwarding processing threads is adjusted, so that the affinity between the processor of at least 1 of the K forwarding processing threads and the switch port served by the processor of the at least 1 of the K forwarding processing threads is increased (if the affinity between the processor of the forwarding processing thread and the switch port served by the processor of the forwarding processing thread is higher than the preset range).

By way of further example, assume that the adjustment trigger condition includes the following conditions: if the load balance among the K forwarding processing threads is lower than the preset range, the load balance among the K forwarding processing threads is improved (for example, the load balance among the K forwarding processing threads is higher than the preset range).

In a case that it is detected that the state attributes of the K forwarding processing threads of the vSwitch satisfy a preset adjustment triggering condition, a specific implementation manner of adjusting the switch port served by at least 1 forwarding processing thread of the K forwarding processing threads may be various, and some possible implementation manners are exemplified below.

Optionally, in some possible embodiments of the present invention, the status attribute of the forwarding processing thread may include, for example, a remaining forwarding resource quota and/or a remaining forwarding resource quota occupation ratio of the forwarding processing thread; wherein, in the case that it is detected that the state attributes of the K forwarding processing threads of the vSwitch satisfy a preset adjustment triggering condition, adjusting the switch ports served by at least 1 forwarding processing thread of the K forwarding processing threads may include:

For example, a higher load balance indicates more balanced load, and a lower load balance indicates more unbalanced load. The second threshold may be, for example, 0.5, 0.6, 0.8, 0.9 or other values, assuming that the value range of the load balancing degree is 0-1.

For example, the load balancing degree may also be represented by a variance of remaining forwarding resource quota of K forwarding processing threads, where a larger variance indicates a lower load balancing degree, and a larger variance indicates a higher load balancing degree, and so on.

It can be understood that the load balance among the K forwarding processing threads is improved by adjusting the switching ports served by at least 1 forwarding processing thread of the K forwarding processing threads, which is beneficial to improving the forwarding resource utilization rate and the adaptive capacity of network traffic change under the virtual architecture.

Optionally, in some possible embodiments of the present invention, the status attribute of the forwarding processing thread includes a remaining forwarding resource quota of the forwarding processing thread; wherein, when detecting that the state attributes of the K forwarding processing threads of the vSwitch satisfy a preset adjustment trigger condition, adjusting the switch ports served by at least 1 forwarding processing thread of the K forwarding processing threads comprises:

or,

The value of the third threshold may be determined according to the total forwarding resource quota of the forwarding processing thread. Assuming that the total forwarding resource quota of the forwarding processing threads (forwarding processing threads x1 or x2) is 100, the third threshold may be equal to 10, 16, 8, 20, or other values, and so on.

It can be understood that when the remaining forwarding resource quota of the forwarding processing thread is small, the switching port served by the forwarding processing thread is adjusted (e.g., reduced or replaced), which is beneficial to improving the load balance among the K forwarding processing threads, and is beneficial to improving the forwarding resource utilization rate under the virtual architecture and the adaptive capability of network traffic change.

Optionally, in some possible embodiments of the present invention, the status attribute of the forwarding processing thread includes a remaining forwarding resource quota occupation ratio of the forwarding processing thread; wherein, when detecting that the state attributes of the K forwarding processing threads of the vSwitch satisfy a preset adjustment trigger condition, adjusting the switch ports served by at least 1 forwarding processing thread of the K forwarding processing threads comprises:

or,

Wherein, the ratio of the surplus forwarding resource line is the ratio of the surplus forwarding resource line to the total forwarding resource line. Wherein the fourth threshold may be, for example, equal to 5%, 10%, 15, 17%, 9%, 20%, 25%, or other values.

It can be understood that when the remaining forwarding resource quota of the forwarding processing thread is relatively small, the switching port served by the forwarding processing thread is adjusted (e.g., reduced or replaced), which is beneficial to improving the load balance among the K forwarding processing threads, and is beneficial to improving the forwarding resource utilization rate under the virtual architecture and the adaptive capacity of the network traffic change.

Optionally, in some possible embodiments of the present invention, the state attribute of the forwarding processing thread includes an affinity between a processor of the forwarding processing thread and a switch port served by the processor;

The inventor researches and realizes that the data transfer efficiency between the processors and the switching ports belonging to the same affinity node is generally higher than the data transfer efficiency between the processors and the switching ports belonging to different affinity nodes, so that the processors of the forwarding processing threads and the switching ports served by the processors belong to the same affinity node as much as possible by adjusting the forwarding processing threads serving the switching ports, and the related data transfer efficiency is improved.

Optionally, in some possible embodiments of the present invention, the affinity node may be a Non-Uniform Memory Access Architecture (NUMA) node or other nodes that can describe object affinity.

Optionally, in some possible embodiments of the present invention, the status attribute of the forwarding processing thread includes a forwarding resource quota actually occupied by critical traffic of an exchange port served by the forwarding processing thread.

or,

if it is detected that the forwarding resource quota actually occupied by the critical traffic of the switching port j5 served by the forwarding processing thread x1 among the K forwarding processing threads is smaller than the forwarding resource quota nominally occupied by the critical traffic of the switching port j5, and it is detected that the remaining forwarding resource quota of the forwarding processing thread x2 among the K forwarding processing threads is greater than or equal to the forwarding resource quota nominally occupied by the critical traffic of the switching port j5, the switching port served by the forwarding processing thread x1 includes a switching port j5 and a switching port j6, and the forwarding processing thread served by the switching port j6 is adjusted to be the forwarding processing thread x2 by the forwarding processing thread x 1.

The priority threshold may be equal to 1 or 2, for example, assuming there are 3 priority levels of traffic, i.e. level 1, level 2 and level 3, assuming there are 4 priority levels of traffic, i.e. level 1, level 2, level 3 and level 4, the priority threshold may be equal to 1, 2 or 3, for example, and so on. The value of the priority threshold can be determined according to specific needs.

It will be appreciated that the above example introduces a possible mechanism that is advantageous for ensuring the forwarding resource quota for high priority traffic. For example, the priority level of the heartbeat packet is usually higher than the priority levels of other flows, so the mechanism based on the above example is favorable for ensuring the forwarding resource amount of the heartbeat packet as much as possible, and for example, the priority level of some core service flows is usually higher than the priority level of common service flows, so the mechanism based on the above example is favorable for ensuring the forwarding resource amount of the core service flows as much as possible, and is favorable for improving the effective utilization rate of the forwarding resources under the virtual architecture and the adaptive capacity of network flow change.

It is to be understood that the foregoing examples only show some possible implementations of adjusting the switch ports served by at least 1 forwarding processing thread of the K forwarding processing threads when it is detected that the state attributes of the K forwarding processing threads of the vSwitch satisfy the preset adjustment trigger condition, and certainly, there may be other possible implementations of adjusting.

To facilitate a better understanding and an implementation of the above-described aspects of the embodiments of the present invention, some specific scenarios are illustrated below.

Referring to fig. 4-a, fig. 4-a is a flowchart illustrating a method for adjusting a switch port of a forwarding processing thread according to another embodiment of the present invention, where the method for adjusting a switch port of a forwarding processing thread according to another embodiment of the present invention may include:

401. after the computing node is powered on, the Host in the computing node initially configures the switching port served by the forwarding processing thread in the vSwitch in the Host.

Wherein one forwarding processing thread may serve one or more switch ports.

Wherein the service relationship between one forwarding processing thread in vSwitch and a switch port may be as shown in fig. 4-b for example.

Among them, in a ServiceChain scenario in the NFV field, there are often adjustments and changes of VAS sequences, such as: a physical host operated by the VAS has a software upgrade scenario and a hardware failure scenario, and at this time, a VM on the physical host needs to be migrated. In a migration scenario of a VAS in ServiceChain, a forwarding flow policy on a vSwitch where the VAS is located needs to be migrated to a target vSwitch where the VAS is migrated. Also for example, the VAS itself may be out of service during operation due to traffic regulations, or due to internal anomalies. For another example, if a certain VAS processing capability becomes a performance bottleneck along with the development of a service, such VAS with the same function needs to be added to the service, and the service processing capability is improved through load balancing.

In the service scenarios illustrated above, the ports related to the VM corresponding to the VAS are embodied as operations of adding, deleting, and changing traffic on the vSwitch, and then the mechanism of this embodiment may be introduced to adjust the deployment.

The detected trigger condition may include, for example, that the VM running on the Host is increased, decreased, or changed. Or a VM adds, reduces or changes its switch port, a forwarding processing thread in a vSwitch adds, reduces or changes, although not limited to the above examples.

402. And the Host detects the state attributes of K forwarding processing threads of the vSwitch in the Host, wherein the state attributes of the forwarding processing threads comprise the remaining forwarding resource quota of the forwarding processing threads and/or the remaining forwarding resource quota occupation ratio of the forwarding processing threads.

Wherein, K forwarding processing threads in the vSwitch are in one-to-one correspondence with K processors in the compute nodes.

403. And under the condition that the state attributes of the K forwarding processing threads of the vSwitch are detected to meet a preset adjustment triggering condition, Host adjusts the switching ports served by at least 1 forwarding processing thread in the K forwarding processing threads, wherein K is a positive integer.

or,

It can be seen that, in this embodiment, by detecting state attributes of K forwarding processing threads of a vSwitch in a host, for example, a remaining forwarding resource amount of the forwarding processing thread and/or a remaining forwarding resource amount proportion of the forwarding processing thread, and on the condition that the state attributes of the K forwarding processing threads of the vSwitch are detected to meet a preset adjustment trigger condition, an exchange port served by at least 1 forwarding processing thread of the K forwarding processing threads is adjusted. Due to the introduction of the mechanism capable of adjusting the switching ports served by the forwarding processing threads according to the state attributes of the forwarding processing threads of the vSwitch, the switching ports served by the forwarding processing threads can be dynamically changed, and the traditional mechanism that the forwarding processing threads and the switching ports served by the forwarding processing threads are always fixedly bound is abandoned, so that the improvement of the utilization rate of forwarding resources and the adaptive capacity of network traffic change under the virtual architecture is facilitated.

Referring to fig. 5, fig. 5 is a flowchart illustrating a method for adjusting a switch port of a forwarding processing thread according to another embodiment of the present invention, where the method for adjusting a switch port of a forwarding processing thread according to another embodiment of the present invention may include:

501. after the computing node is powered on, the Host in the computing node initially configures the switching port served by the forwarding processing thread in the vSwitch in the Host.

Wherein one forwarding processing thread may serve one or more switch ports.

In some computing node configurations for running ServiceChain services, an intelligent physical network card of an Intel or other manufacturer is generally selected as a device for VAS external communication, and in some environments, the physical network card has affinity with a specific NUMA node of a server, so a CPU for processing IO of the physical network card needs to ensure that the physical network card has the same NUMA node, and the performance can be optimal, otherwise, performance degradation of about 30% may occur due to cross-NUMA IO access.

Similarly, virtual switch ports also suffer from NUMA node ownership issues, and virtual switch ports can also suffer performance degradation due to cross-NUMA IO accesses.

The detected trigger condition may include, for example, that the VM running on Host has been added, subtracted, or changed. Or the VM increases, decreases or changes its switching port, or the forwarding processing thread in the vSwitch increases, decreases or changes, or the computing node changes or adds a physical network card, etc., which is not limited to the above examples.

502. The Host detects state attributes of K forwarding processing threads of the vSwitch in the Host, wherein the state attributes of the forwarding processing threads comprise the affinity between processors of the forwarding processing threads and the switching ports served by the processors.

503. And under the condition that the state attributes of the K forwarding processing threads of the vSwitch are detected to meet a preset adjustment triggering condition, Host adjusts the switching ports served by at least 1 forwarding processing thread in the K forwarding processing threads, wherein K is a positive integer.

Optionally, in some possible embodiments of the present invention, in a case that it is detected that the state attributes of the K forwarding processing threads of the vSwitch meet a preset adjustment trigger condition, adjusting the switch ports served by at least 1 forwarding processing thread of the K forwarding processing threads may include:

Specifically, for example, the adjusting of the forwarding processing thread serving the switch port j4 to the forwarding processing thread x4 by the forwarding processing thread x3 includes: and when the remaining forwarding resource limit of the forwarding processing thread x4 is greater than the forwarding resource limit occupied by the traffic of the switching port j4, adjusting the forwarding processing thread serving for the switching port j4 from the forwarding processing thread x3 to the forwarding processing thread x 4.

Optionally, in some possible embodiments of the invention, the affinity node may be a non-uniform memory access architecture (NUMA) node or other node that can describe object affinity.

It can be seen that, in this embodiment, by detecting state attributes of K forwarding processing threads of a vSwitch in a host, for example, affinity between a processor of the forwarding processing thread and a switching port served by the processor, and the like, and in a case that it is detected that the state attributes of the K forwarding processing threads of the vSwitch satisfy a preset adjustment trigger condition, an switching port served by at least 1 forwarding processing thread of the K forwarding processing threads is adjusted. Due to the introduction of the mechanism capable of adjusting the switching ports served by the forwarding processing threads according to the state attributes of the forwarding processing threads of the vSwitch, the switching ports served by the forwarding processing threads can be dynamically changed, and the traditional mechanism that the forwarding processing threads and the switching ports served by the forwarding processing threads are always fixedly bound is abandoned, so that the improvement of the utilization rate of forwarding resources and the adaptive capacity of network traffic change under the virtual architecture is facilitated.

Referring to fig. 6, fig. 6 is a flowchart illustrating a method for adjusting a switch port of a forwarding processing thread according to another embodiment of the present invention, where the method for adjusting a switch port of a forwarding processing thread according to another embodiment of the present invention may include:

601. after the computing node is powered on, the Host in the computing node initially configures the switching port served by the forwarding processing thread in the vSwitch in the Host.

When the Host initially configures the switching port served by the forwarding processing thread, the forwarding processing thread can be preferentially configured for the switching port with higher traffic priority.

Wherein one forwarding processing thread may serve one or more switch ports.

For example, in a ServiceChain scenario, the VM supports the VAS function, and simultaneously needs a virtual network card of another network plane for management and environment configuration. Because the number of hardware network cards of the compute node is limited, a virtual network card of a management plane of the VM may be connected to a port of the vSwitch, and at this time, the service traffic and the management traffic are completed on the same vSwitch, although the traffic of the management plane is not large, the basic capability of the management plane needs to be guaranteed for processing, otherwise, the VAS may be affected by heartbeat interruption. Therefore, the ports associated with such management plane have higher priority, and the forwarding resource amount of such high-priority ports needs to be guaranteed as much as possible.

Of course, the forwarding resource quota of some core services should be guaranteed as much as possible.

602. The method comprises the steps that the Host detects state attributes of K forwarding processing threads of vSwitch in the Host, wherein the state attributes of the forwarding processing threads comprise forwarding resource limits actually occupied by key flow of an exchange port served by the forwarding processing threads.

The priority threshold may be equal to 1 or 2, assuming there are 3 priority levels of traffic, i.e. level 1, level 2 and level 3, assuming there are 4 priority levels of traffic, i.e. level 1, level 2, level 3 and level 4, the priority threshold may be equal to 1, 2 or 3, for example, and so on. The value of the priority threshold can be determined according to specific needs.

603. And under the condition that the state attributes of the K forwarding processing threads of the vSwitch are detected to meet a preset adjustment triggering condition, Host adjusts the switching ports served by at least 1 forwarding processing thread in the K forwarding processing threads, wherein K is a positive integer.

or,

It can be seen that, in this embodiment, by detecting state attributes of K forwarding processing threads of a vSwitch in a host, the state attributes of the forwarding processing threads include forwarding resource amounts actually occupied by critical traffic of an exchange port served by the forwarding processing threads, and when it is detected that the state attributes of the K forwarding processing threads of the vSwitch meet a preset adjustment triggering condition, an exchange port served by at least 1 forwarding processing thread of the K forwarding processing threads is adjusted. Due to the introduction of the mechanism which can adjust the switching ports served by the forwarding processing threads according to the state attributes of the forwarding processing threads of the vSwitch, the switching ports served by the forwarding processing threads can be dynamically changed, and the traditional mechanism that the forwarding processing threads and the switching ports served by the forwarding processing threads are always fixedly bound is abandoned, so that the improvement of the utilization rate of forwarding resources and the adaptive capacity of network traffic change under the virtual architecture is facilitated.

Among other things, the above examples introduce possible mechanisms that are advantageous for ensuring the forwarding resource quota for high priority traffic. For example, the priority level of the heartbeat packet is usually higher than the priority levels of other flows, so the mechanism based on the above example is favorable for ensuring the forwarding resource amount of the heartbeat packet as much as possible, and for example, the priority level of some core service flows is usually higher than the priority level of common service flows, so the mechanism based on the above example is favorable for ensuring the forwarding resource amount of the core service flows as much as possible, and is favorable for improving the effective utilization rate of the forwarding resources under the virtual architecture and the adaptive capacity of network flow change.

The embodiment of the invention also provides a relevant device for implementing the scheme.

Referring to fig. 7-a, an apparatus 700 for adjusting a switch port of a forwarding processing thread according to an embodiment of the present invention may include:

a detecting unit 710, configured to detect state attributes of K forwarding processing threads of a virtual switch vSwitch in a host;

or, the adjusting unit 720 is specifically configured to, if it is detected that the remaining proportion of forwarding resource quota of forwarding processing thread x1 in the K forwarding processing threads is smaller than or equal to a fourth threshold, and it is detected that the proportion of remaining forwarding resource quota of forwarding processing thread x2 in the K forwarding processing threads is larger than the fourth threshold, and in a case that the forwarding processing thread serving K3 switching ports of the vSwitch is adjusted to the forwarding processing thread x2 by the forwarding processing thread x1, and the forwarding processing thread serving K4 switching ports of the vSwitch is adjusted to the forwarding processing thread x1 by the forwarding processing thread x2, enable the remaining proportions of forwarding resource quota of the forwarding processing thread x2 and the forwarding processing thread x1 to be both larger than the fourth threshold, adjust the forwarding processing threads serving K3 switching ports to the forwarding processing thread x1 to the forwarding processing thread x2, and adjusting the forwarding processing threads serving the k4 switching ports to be the forwarding processing thread x1 by the forwarding processing thread x2, wherein the k3 and the k4 are positive integers.

the adjusting unit 720 is specifically configured to, when it is detected that the processor of the forwarding processing thread x3 in the K forwarding processing threads and the switch port j4 of the vSwitch that the processor serves do not belong to the same affinity node, adjust the forwarding processing thread serving for the switch port j4 from the forwarding processing thread x3 to the forwarding processing thread x4, where the processor of the forwarding processing thread x4 and the switch port j4 belong to the same affinity node.

For example, the adjusting unit 720 is specifically configured to, when it is detected that the processor of the forwarding processing thread x3 in the K forwarding processing threads and the switching port j4 of the vSwitch that the processor serves do not belong to the same affinity node, and when it is detected that the remaining forwarding resource quota of the forwarding processing thread x4 is greater than the forwarding resource quota occupied by the traffic of the switching port j4, adjust the forwarding processing thread serving for the switching port j4 from the forwarding processing thread x3 to the forwarding processing thread x4, where the processor of the forwarding processing thread x4 and the switching port j4 belong to the same affinity node.

Optionally, in some possible embodiments of the present invention, the affinity node is a non-uniform memory access NUMA node.

Optionally, in some possible embodiments of the present invention, the status attribute of the forwarding processing thread includes a forwarding resource quota actually occupied by the critical traffic of the forwarding processing thread,

the adjusting unit 720 is specifically configured to, if it is detected that a forwarding resource quota actually occupied by a critical traffic of an exchange port j5 served by a forwarding processing thread x1 in the K forwarding processing threads is smaller than a forwarding resource quota nominally occupied by a critical traffic of the exchange port j5, an exchange port served by the forwarding processing thread x1 includes an exchange port j5 and an exchange port j6, and adjust the forwarding processing thread served by the exchange port j6 from the forwarding processing thread x1 to a forwarding processing thread x 2;

or,

the adjusting unit 720 is specifically configured to, if it is detected that a forwarding resource quota actually occupied by a critical traffic of an exchange port j5 served by a forwarding processing thread x1 in the K forwarding processing threads is smaller than a forwarding resource quota nominally occupied by a critical traffic of the exchange port j5, and it is detected that a remaining forwarding resource quota of a forwarding processing thread x2 in the K forwarding processing threads is greater than or equal to a forwarding resource quota nominally occupied by a critical traffic of the exchange port j5, an exchange port served by the forwarding processing thread x1 includes an exchange port j5 and an exchange port j6, and adjust the forwarding processing thread served by the exchange port j6 to be the forwarding processing thread x2 by the forwarding processing thread x 1.

It can be understood that the functions of the modules of the apparatus 700 for adjusting the switch port of the forwarding processing thread in this embodiment may be specifically implemented according to the method described in the foregoing embodiment, and the specific implementation process of the method may refer to the relevant description in the foregoing embodiment, which is not described herein again. The means 700 for adjusting the switch port of the forwarding processing thread may be, for example, Host or vSwitch, or as shown in fig. 7-b for example, the means 700 for adjusting the switch port of the forwarding processing thread may be deployed in Host, or as shown in fig. 7-c for example, the means 700 for adjusting the switch port of the forwarding processing thread may be deployed in vSwitch.

Due to the introduction of the mechanism capable of adjusting the switching ports served by the forwarding processing threads according to the state attributes of the forwarding processing threads of the vSwitch, the switching ports served by the forwarding processing threads can be dynamically changed, and the traditional mechanism that the forwarding processing threads and the switching ports served by the forwarding processing threads are always fixedly bound is abandoned, so that the improvement of the utilization rate of forwarding resources and the adaptive capacity of network traffic change under the virtual architecture is facilitated.

Optionally, in some possible embodiments of the present invention, the status attribute of the forwarding processing thread includes a remaining forwarding resource quota occupation ratio of the forwarding processing thread; wherein, in the aspect of adjusting the switch ports served by at least 1 forwarding processing thread of the K forwarding processing threads when detecting that the state attributes of the K forwarding processing threads of the vSwitch meet a preset adjustment trigger condition, the host 820 may specifically be configured to:

or,

wherein, in the aspect of adjusting the switch ports served by at least 1 forwarding processing thread of the K forwarding processing threads when detecting that the state attributes of the K forwarding processing threads of the vSwitch meet a preset adjustment trigger condition, the host 820 may specifically be configured to:

Optionally, in some possible embodiments of the present invention, the status attribute of the forwarding processing thread includes a forwarding resource quota actually occupied by the critical traffic forwarded by the forwarding processing thread.

or,

The priority threshold may for example be equal to 1 or 2, assuming there are 3 priority levels of traffic, i.e. level 1, level 2 and level 3, assuming there are 4 priority levels of traffic, i.e. level 1, level 2, level 3 and level 4, the priority threshold may for example be equal to 1, 2 or 3, and so on. The value of the priority threshold can be determined according to specific needs.

Due to the introduction of the mechanism capable of adjusting the switching ports served by the forwarding processing threads according to the state attributes of the forwarding processing threads of the vSwitch, the switching ports served by the forwarding processing threads can be dynamically changed, and the traditional mechanism that the forwarding processing threads and the switching ports served by the forwarding processing threads are always fixedly bound is abandoned, so that the improvement of the utilization rate of forwarding resources and the adaptive capacity of network traffic change under the virtual architecture is facilitated.
