Example Embodiment

[0052] In the preferred embodiment 1, the elastic scaling of VM resources when the above-mentioned first node is a VM:

[0053] After the most downstream VM resources have created the elastic scaling rules, each VM is bound together to form a virtualized network function (Virtualised Network Function, referred to as VNF) through Server Load Balancing (referred to as SLB), which refers to network elements. On the other hand, compared to monitoring the index information of the VNF level, monitoring the index information of each VM under the VNF is more accurate and timely. The VM monitoring index here is mainly composed of system information such as memory, CPU, hard disk, and bandwidth. Each VM performs real-time status monitoring, and judges whether it meets the elastic scaling conditions by itself. If the VM itself cannot judge whether the elastic scaling rule conditions are met, the monitored information data is handed over to the upstream VNF node for judgment. If the scaling ...

Example Embodiment

[0066] Preferred Embodiment 2 VM resource elastic scaling processing when the above-mentioned first node is a VNF

[0067] In addition to the possibility of judging the downstream VM indicator information, the VNF node also needs to judge and monitor its own indicator information at the same time. The monitoring indicators here mainly involve system information such as memory, CPU, hard disk, bandwidth, and business indicators carried on the network element side. Information, such as the number of transactions per second (TransactionsPerSecond, referred to as TPS), the load of a certain business, etc. If the VNF itself cannot determine whether the conditions of the elastic scaling rule are met, all the monitored information and data will be forwarded to the upstream The VNFM node judges, if the scaling conditions are met, the VNF performs elastic scaling processing and sends related requests to the VNFM. When the overall system load is low, if the scaling conditions are reached, t...

Example Embodiment

[0080] Preferred embodiment three: VM resource elastic scaling processing when the above-mentioned first node is a VNFM:

[0081] In addition to the possibility of judging downstream VNF indicator information, VNFM nodes also need to judge and monitor their own indicator information. The monitoring indicators here mainly involve system information such as memory, CPU, hard disk, bandwidth, and network element processing capabilities. If it reaches scalability If the condition is met, the elastic scaling process is performed. When the overall system load is low, if the shrinking condition is reached, an elastic scaling request is triggered, and a VM resource request change message is sent to NFVO, and a series of state transition operations are performed on the VM. Release VM resources, and then perform SLB processing on the VNFM to reduce the system TCO; when the overall load of the system is high, if the expansion conditions are met, an elastic scaling request is triggered, and a...

Abstract

The invention provides an elastically telescopic processing method, device and system for VM resources. The method comprise that according to VM indication information in a first node, the first node or an adjacent upstream node thereof determines that the first node reaches a preset threshold for VM resource elastically telescopic processing; and the upstream node of the first node is used to carry out VM resource elastically telescopic processing on the first node. The problems that interaction of NFVO information is too much and the impact is large in the prior art are solved, and thus, information interaction of NFVO is reduced, and impact on the NFVO is reduced.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method, device and system for elastically scaling virtual machine VM resources. Background technique [0002] In the current communications field, how to build efficient and reliable elastic scaling services in telecom equipment is an important and core problem facing the industry. [0003] Most of the current solutions are not perfect in terms of security and reliability, especially the virtual machine (Virtual Machine, referred to as VM) elastic scaling index monitoring part. Currently, the monitoring of virtual machine index information is mostly based on a centralized single point The monitoring method is the main method, in which the monitoring nodes are mostly placed upstream, and most of them are Network Functions Virtualization Orchestrator (NFVO for short). This situation has too much impact on NFVO. single point of failure. [0004] figure 1 It is a r...
