Detailed Description
Before describing the virtual link monitoring scheme of the embodiment of the present invention in detail, first, a Network Function Virtualization (NFV) is briefly introduced.
The aim of NFV is to replace proprietary dedicated network element equipment of a communication network by computing, storage and network switching equipment based on industry standards. The method has the advantages that on one hand, standard-based Information Technology (IT) equipment is low in cost and can save huge investment cost for operators, and on the other hand, an open Application Programming Interface (API) can help the operators to obtain more and more flexible network capacity. The functions of the network equipment can be independent of special hardware through software and hardware decoupling and function abstraction, resources can be shared fully and flexibly, rapid development and deployment of new services are achieved, and automatic deployment, elastic expansion, fault isolation, self-healing and the like are carried out based on actual service requirements.
When NFV is used for network design and deployment, VL refers to a set of connection points, including connectivity relationships between connection points and related target performance indicators, such as: quality of service (QoS) metrics such as bandwidth, delay, etc. The VL may interconnect two or more entities (which may be components inside a Virtualized Network Function (VNF), VNFs (VNFs represent a complex form of VNF), or Physical Network Function (PNF) modules), and the VL needs to be supported by a virtual Network (VN, virtual Network) of a Network Function Virtualization Infrastructure (NFVI).
As shown in fig. 1, two access points (pops) may be included in the NFVI, which are denoted as NFVI-PoP1 and NFVI-PoP 2; each connection point comprises at least one Network Controller (Network Controller); also included in each connection point are VNF components, denoted as VNF1 and VNF2, respectively. The logical concept of VL may be mapped to a virtual Network link, a Wide Area Network (WAN) link, and a physical link inside a data center (the data center in the embodiment of the present invention refers to a computer room providing NFV infrastructure) when a Network function is deployed, or may be a combination of the three specific links.
In addition, as shown in fig. 1, in addition to NFVI, a Virtualized Infrastructure Manager (VIM) is further included, each NFVI-PoP is connected to a VIM, and one or more VIMs are connected to NFVO; the network function module management system further comprises a virtualized network function module Manager (VNFM), wherein the VNFM is respectively connected with each VIM in a direct mode, and interacts with the VIM through NFVO in an indirect mode; in addition, the method further comprises the following steps: a PNF Endpoint (PNF Endpoint 1) (i.e., a physical link), where the PNF Endpoint 1 may be mixed with the VNF and located at the NFVI-PoP, or may be located at a Network access Point (Network Point of presence, N-PoP), and is connected to the VNF through a wide area Network link; the wide area network is managed by a wide area network Infrastructure Manager (WIM), which is connected to the NFVO; the system also comprises a Network Function Virtualization Orchestrator (NFVO), wherein the NFVO is respectively connected with the wide area Network infrastructure manager, the VIM and the VNFM.
In the process of network service instantiation or deployment, how to select a proper data center for VNF instantiation or deployment to ensure that an underlying network supporting VL implementation can meet the QoS requirements of VL is an important issue. In particular, when a VL requires multiple types of underlying network support implementations, how to guarantee in advance through measurements that the VL can meet performance requirements after instantiation or deployment.
To solve the above problem, as shown in fig. 1, currently, the performance indexes of all links inside a data center are measured by VIM, a wide area network Infrastructure Manager (WIM) measures the performance indexes of all links between different data centers, and an Element Management system (EM) measures the performance indexes of all links inside a physical (i.e. non-virtualized) room. Then, NFVO or a network management system (NM) needs to collect and combine the information of the three aspects, for example, the virtual link, the wan link performance, and the physical link in the data center are connected to form a potential VL, so as to obtain a performance index of a potential VL deployment mode. On one hand, the mode has very large measurement workload and low efficiency; on the other hand, the coordination between NFV arrangement and Management (MANO, Management and organization) and NM needs to be summarized and combined by one party, and the requirements on MANO and NM are high. In addition, the performance index measurement has high requirements on physical Network infrastructure, and needs to be supported by Software Defined Network (SDN) related functional devices, and then, the support of the existing Network of most operators to the SDN cannot meet the measurement requirements.
In addition, delay performance in VL performance index requirements may change greatly over time or under network load, and different services deployed on the virtualization platform have different requirements for delay performance accuracy. Therefore, if the above method is adopted, a policy needs to be performed according to the service with the most stringent requirement on the delay precision, and the cost of the virtualization infrastructure is greatly increased.
Based on this, the following examples of the present invention are proposed.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The embodiment of the invention provides a virtual link monitoring method. Fig. 2 is a schematic flowchart of a virtual link monitoring method according to an embodiment of the present invention; as shown in fig. 2, the method includes:
step 201: and screening the data centers to obtain a data center set with available resources meeting the requirements of the virtualized network functional resources.
Step 202: and obtaining a time delay measurement result of the virtual network function software and/or the embedded function software aiming at any data center in the data center set based on the deployed virtual network function software and/or the embedded function software for time delay measurement.
The embodiment of the invention is used for measuring and monitoring the time delay of the network resource before the virtual network function is instantiated or deployed.
In this embodiment, in order to reduce overhead and improve the efficiency of delay monitoring, delay monitoring is not performed on all data centers, but a data center set is formed by screening partial data centers whose available resources in all data centers can support the deployment of a virtualized network function, and delay measurement is performed on the data centers in the data center set.
As an embodiment, the screening the data centers includes: screening the data centers according to at least one of the following information: computing resources of the virtual network function, storage resources of the virtual network function, network bandwidth requirements, acceleration resources, geographic location of the data center.
In this embodiment, according to the requirement of the virtual network function resource, the method specifically includes: at least one of computing resources of the virtual network function, storage resources of the virtual network function, and network bandwidth requirements, and/or speeding up resource requirements and geographic location of the data center to screen the data center. In practical applications, a Virtual Network Function Descriptor (VNFD) is configured for a Virtual Network Function (VNF), where the VNFD includes resources required by the corresponding VNF, and the resources include at least one of computing resources, storage resources, and Network bandwidth requirements; in the process of screening the data centers, screening can be performed based on the resources required in the VNFD, so as to obtain the data centers capable of meeting the VNF requirements.
In another embodiment, in order to reduce the measurement overhead and improve the efficiency of the delay monitoring, the delay monitoring is not always performed on the data centers, except that the delay monitoring is not performed on all the data centers.
As an example, before obtaining the latency measurement of the virtual network function software and/or the embedded function software for any data center in the set of data centers, the method further comprises:
deploying virtual network function software and/or embedded function software for time delay measurement before instantiation or deployment of a virtual network function, so as to perform time delay measurement on any data center in the data center set based on the virtual network function software and/or the embedded function software; and the time interval between the first moment when the virtual network function software and/or the embedded function software starts the time delay measurement and the second moment when the virtual network function is instantiated or deployed is determined according to the time delay measurement requirement.
In this embodiment, in a first aspect, a time interval between a first time when a data center in a screened data center set is started to perform delay measurement and a second time when a virtual network function is instantiated or deployed is determined according to a delay measurement requirement, and it can be understood that the delay measurement of the data center is started a period of time before the virtual network function is instantiated or deployed, and specifically how long ahead of time can be determined according to the delay measurement requirement of the data center. As an example, if the delay measurement may be to observe the delay performance at least for the duration of T, then delay monitoring is initiated at least by advancing the duration of T.
Therefore, the embodiment of the invention does not monitor the time delay of all data centers or monitor the time delay of the data centers all the time, thereby achieving the effects of reducing the overhead and improving the efficiency of time delay monitoring.
In a second aspect, before instantiation or deployment of a virtual network function, the embodiment of the present invention deploys virtual network function software and/or embedded function software for latency measurement, so as to perform latency measurement on any data center in the set of data centers based on the virtual network function software and/or embedded function software.
As an embodiment, the deploying the virtual network function software and/or the embedded function software for latency measurement includes: if the data center provides the virtual network function, deploying virtual network function software in the data center; if the machine room which provides the virtual network function is the machine room in which the physical network function is located, embedded function software is deployed in the machine room in which the physical network function is located.
In this embodiment, in order to measure the delay performance of the virtual link, the delay monitoring function needs to be respectively deployed at the positions of the two connection points corresponding to the virtual link. As an example, if two connection points corresponding to the virtual link are both mapped to the data center, the delay monitoring function is deployed in each of the two data centers. As another example, if two connection points corresponding to the virtual link are respectively mapped to a data center and a machine room where the physical network function is located, the time delay monitoring function is respectively deployed in the data center and the machine room where the physical network function is located.
In this embodiment, if the infrastructure providing the virtual network function is a data center, that is, the connection point of the virtual link is mapped to the data center, the virtual network function software is deployed in the data center, and the virtual network function software may be lightweight function software, that is, software occupying a small amount of computing resources and storage resources. The virtual network function software can be configured in advance according to the precision requirement of the virtual network function on the time delay, and different time delay monitoring methods and monitoring intervals can be designed based on different data centers to obtain time delay monitoring results. If the infrastructure providing the virtual network function is a machine room where the physical network function is located, that is, the connection point of the virtual link is located in the machine room where the physical network function is located, the deployment of the delay monitoring function can be completed only by the support of NM and EM, and therefore, the measurement of the delay needs to be realized by deploying embedded functional software (that is, functional software carried by a hardware entity).
In this embodiment, the delay measurement result is sent by the virtual network function software and/or the embedded function software, and sequentially reaches the network function virtualization orchestrator via the network element management system and the network management system; or the time delay measurement result is sent by the virtual network function software and/or the embedded function software and reaches the network function virtualization orchestrator through the network function virtualization manager.
It is understood that the virtual link monitoring method of this embodiment may be applied to a network function virtualization orchestrator, or may be applied to monitoring equipment including a network element management system, a network management system, and a network function virtualization orchestrator, or may also be applied to monitoring equipment including a network function virtualization manager and a network function virtualization orchestrator.
In an embodiment, the method further comprises: and selecting a data center meeting the instantiation or deployment requirement of the virtual network function and virtualized resources of the data center according to the time delay measurement result.
In this embodiment, after the deployment of the delay function is completed, that is, after the deployment of the virtual network function software and/or the embedded function software for delay measurement is completed, the delay measurement function of the virtual network function software and/or the embedded function software may be started. The measurement scheme of the embodiment of the invention has no extra requirements on network infrastructure, for example, no extra SDN function is required to be supported, and the measurement can be carried out based on the existing network. On the other hand, the measurement scheme of the embodiment of the invention performs measurement based on the virtual network function, and compared with the traditional VIM, the measured time delay performance is closer to the actual application situation after the virtual network function is instantiated.
In the embodiment of the invention, as an implementation mode, time delay measurement can be started simultaneously for all data centers in a data center set; accordingly, the delay measurement for different data centers requires that the delay measurement results be obtained sequentially.
As another embodiment, the selecting, based on the deployed virtual network function software and/or embedded function software for latency measurement, a data center and virtualized resources of the data center that meet the instantiation or deployment requirement of a virtual network function according to the latency measurement result includes: sorting the data centers in the data center set according to priority based on a deployment strategy; the time delay measurement results are sequentially obtained based on the priority ranking result; and if the obtained time delay measurement result meets the requirement of instantiation or deployment of the virtual network function, terminating the time delay measurement of the data center in the data center set.
In the embodiment, the data centers in the data center set are sorted according to the priority based on the deployment strategy; sequentially starting time delay measurement of the data center based on the priority ranking result to obtain a time delay measurement result; if the obtained time delay measurement result meets the virtual network function instantiation or deployment requirement, the time delay measurement is terminated, that is, the time delay measurement of all data centers in the data center set does not need to be completed, and the data center which can meet the virtual network function instantiation or deployment requirement is found. The embodiment can also reduce the overhead and improve the efficiency of time delay monitoring.
Fig. 3 is a schematic diagram of a data transmission path in a virtual link monitoring method according to an embodiment of the present invention; as shown in fig. 3, two paths are reported for the delay measurement result: firstly, a time delay measurement result is reported to an NM through an EM, the NM sends the time delay measurement result to an NFVO through modes of geographic position information indication and the like, and the NFVO determines resources instantiated by virtual network functions; secondly, the delay measurement result is reported to the NFVO through the VNFM, and the NFVO determines the resources instantiated by the virtual network function.
The following describes a virtual link monitoring method according to an embodiment of the present invention with reference to a specific example.
Fig. 4 is a schematic diagram of an application of the virtual link monitoring method according to the embodiment of the present invention; as shown in fig. 4, a Radio Access Network (RAN) is based on a Centralized Unit (CU) and Distributed Unit (DU) architecture discussed in the third generation partnership Project (3 GPP), where CUs may be deployed in the form of VNFs, referred to as virtual central units (vcus), and currently DU functionality tends to be implemented using legacy proprietary equipment and deployed in the form of PNFs. The links between the vcus and the DUs may include Virtual links (Virtual links) and Physical links (Physical links), which may include, for example, Virtual Link # 1 and Virtual Link # 2; the Physical links may include, for example, Physical Link # 1 and Physical Link # 2, as shown in detail with reference to the upper half of fig. 4. The corresponding logical relationship may be as shown in the lower half of fig. 4, and for the virtual link, may include a virtual Network Resource 1(virtual Network Resource #1) corresponding to the infrastructure (e.g., in the machine room) where the vCU is located and a virtual Network Resource 2(virtual Network Resource #2) corresponding to the wide area Network; for a Physical link, only the Physical Network (Physical Network) within the infrastructure where the DU is located is included.
When RAN is deployed, there is a high requirement for network transmission delay between CU and DU, which is in the order of milliseconds (ms), and as an example, the delay requirement may be 3-5 ms. Before the vCU is instantiated or deployed, network delay needs to be monitored to ensure transmission requirements between the CU and the DU. Usually the transmission between CUs and DUs is across a wide area network, as mentioned before, NFV infrastructure delay measurements are difficult to achieve, especially with delay accuracy of the order of ms. The specific situation in which this scheme is applied to this embodiment is as follows:
1) for CUs, based on subscription information of VIM, NFVO screens data centers according to the computing resource requirements of the CU virtual network function and the geographical position relationship of the machine room where the DU physical network function is located, and a data center set capable of deploying the CU virtual network function is obtained.
2) And respectively designing delay measurement function software according to the delay requirements of the CU and the DU, wherein the delay measurement function software corresponding to the CU is virtual network function software, and the delay measurement function software corresponding to the DU is embedded function software. Here, the latency monitoring software may also be provided by the suppliers of the CU virtual network function and the DU physical network function, respectively.
3) And respectively deploying the time delay measurement function software corresponding to the CU in the screened data center by the NFVO or the NM, deploying the time delay measurement function software corresponding to the DU in the DU physical network function or a machine room where the DU physical network function is located, and starting time delay measurement monitoring.
4) After the time delay measurement monitoring is completed, one mode is that the time delay measurement result can be reported to NM through EM and sent to NFVO by NM; the other mode is that the time delay measurement result is reported to the NFVO through the VNFM, and finally the NFVO determines the resources instantiated or deployed by the CU virtual network function to complete the CU instantiation and the establishment of the RAN network service.
By adopting the technical scheme of the embodiment of the invention, on one hand, the data center is screened, the time delay measurement range is reduced, the measurement overhead is reduced, and the time delay monitoring efficiency is improved; on the other hand, the delay measurement is completed through the functional software (namely, the virtual network functional software and/or the embedded functional software) for the delay measurement, no additional requirement is required on network infrastructure, and the delay performance is closer to the application condition of the virtual network function instantiation.
The embodiment of the invention also provides a virtual link monitoring device.

the obtaining unit 32 is configured to obtain a delay measurement result of the virtual network function software and/or the embedded function software for any data center in the data center set based on the deployed virtual network function software and/or the embedded function software for delay measurement.
