Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
In the description of the present invention, "/" means "or" unless otherwise specified, for example, a/B may mean a or B. "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. Further, "at least one" means one or more, "a plurality" means two or more. The terms "first", "second", and the like do not necessarily limit the number and execution order, and the terms "first", "second", and the like do not necessarily limit the difference.
The inventive concept of the present invention is described below: currently, NFV is used to decouple the software and hardware of the telecommunication network element functions, and deploy various network functions on a general server, switch, and storage device to reduce the dependency on dedicated hardware. Specifically, NFV implements network functions by running software on a series of server hardware that conforms to industry standards, thereby changing the architecture of the network, and because these software can be dynamically moved or instantiated in different locations in the network as required without having to install new devices, it is possible to make network device functions no longer depend on dedicated hardware, resources can be shared sufficiently and flexibly, and rapid development and deployment of new services are achieved. In the NFV system architecture shown in fig. 1, a Management and organization system (MANO Network element) includes NFVO, virtual Network Function Manager (VNFM), and Virtualized Infrastructure Manager (VIM); in the instantiation process, the MANO Network element acquires an instantiation file from a Storage Network element (Virtual Storage) of a Network Function Virtualization Infrastructure (NFVI), and performs instantiation operation according to the acquired instantiation file, so that the MANO Network element needs to depend on the common cooperation of instantiation files such as an image file, a function installation package file, a template file and the like provided by a service provider in the instantiation process.
Based on the technology, the invention discovers that different types of instantiated files of different manufacturers are independently maintained in different NFVOs, the quantity is huge, file version updating cannot be traced, a file directory capable of carrying out consistency global management on the instantiated files is lacked, so that target instantiated files acquired by a MANO network element from a storage network element have the phenomena of inconsistent versions, tampering, damage and the like in the process of deployment, updating, capacity expansion and regeneration of a VNF, and instantiation failure is caused.
In view of the above technical problems, the present invention considers that when an instantiated file is registered, NFVO collects the registration information of the instantiated file, sends the registration information to a blockchain network, and stores the registration information of each instantiated file by using the technical characteristics of the blockchain network that can maintain in multiple ways, support tracing and cannot be tampered, so as to form a complete and real file directory of the instantiated file for MANO network elements to query and perform consistency check on the instantiated file.
Based on the above inventive concept, an embodiment of the present invention provides a method for managing virtual network functions, which is applied to the VNF management system 10 shown in fig. 2, where the VNF management system 10 includes an NFVO100, a blocking networking network 200, a storage network element 300, and a MANO network element 400; the blockchain network 200 includes a plurality of blockchain nodes (as shown in fig. 2, the plurality of blockchain nodes includes a blockchain node 201, a blockchain node 202, and a blockchain node 203, which are only exemplarily shown as three blockchain nodes, and there may be more or less blockchain nodes in the implementation).
The NFVO100 may be connected to any block link point in the block chain network, and the storage network element 300 is connected to the NFVO100 and the MANO network element 400, respectively. Illustratively, NFVO100 is connected to block link point 201.
It should be noted that, in the implementation process, the VNF management system 10 may have more NFVOs and multiple MANO network elements, but since each NFVO and each MANO network element perform the same function in the VNF management system 10 and the connection relationship is the same as the above connection relationship, only one NFVO100 and one MANO network element 400 are shown in fig. 2 by way of example.
As shown in fig. 3, the method includes S501-S505:
s501, the NFVO acquires the registration information of the first instantiation file.
The registration information is used for registering the first instantiation file in the NFVO.
Specifically, after publishing the new instantiated file, the VNF vendor sends the registration information of the new instantiated file to the NFVO, so that the NFVO performs a process of subsequently storing the instantiated file.
It should be noted that the instantiated file may include a VNF image file, a function installation package file, and a template file, the registration information may include a file name, a file size, a file type, a provider name, a version serial number, a validity period of use, authorization information, a disabled/available state, and the like of the instantiated file, and the instantiated file may be filled in on a preset interface when the VNF provider provides the first instantiated file to the NFVO.
Optionally, the registration information provided in the embodiment of the present invention may further include a target identification code, a download link, and a first hash value.
The object identification code is used for identifying the first instantiated file, the download link is used for downloading file data of the first instantiated file from the storage network element, and the first hash value is used for verifying the file data of the first instantiated file.
It should be noted that, in the registration information, the target identification code, the download link, and the first hash value correspond to each other.
As shown in fig. 4, S501 may specifically include S5011-S5013:
s5011, the NFVO generates the target identification code according to the first instantiation file.
Specifically, the target identifier is automatically generated by the NFVO according to the first instantiation file.
S5012, the NFVO generates a first hash value according to the file data of the first instantiated file based on a hash algorithm.
Specifically, the NFVO collects file data of the first instantiated file, and generates a first hash value based on a hash algorithm.
It should be noted that the first hash value may also be generated by the storage network element after the NFVO sends and stores the file data of the first instantiation file to the storage network element.
S5013, the NFVO stores the file data of the first instantiation file in the storage network element, and acquires the download link generated by the storage network element.
The storage network element is used for providing centralized storage/backup and downloading services for the instantiated files.
Specifically, after receiving the file data of the first instantiated file, the storage network element generates a download link, and sends the download link to the NFVO.
S502, the NFVO sends the registration information to the block chain node.
Specifically, the NFVO sends the registration information to the blockchain node, so that the blockchain node generates first assigned value data according to the registration information, and stores the first assigned value data in the blockchain network by using a consensus mechanism.
Wherein the first assigned data includes data that is broadcast among a plurality of block chain nodes and is used to record registration information.
S503, the block chain node receives the registration information of the first instantiated file sent by the network function virtualization orchestrator NFVO.
And S504, generating first assigned value data by the block link points according to the registration information.
Optionally, S504 provided in the embodiment of the present invention may specifically include: and generating first assigned value data according to a preset data format.
The preset data format comprises various data which are in one-to-one correspondence with various data contained in the registration information.
Specifically, the block link points include Software Development Kit (SDK), and after receiving the registration information, the SDK extracts various data from the registration information, and performs assignment operation according to a preset data format agreed with NFVO to generate first assignment data.
S505, the block link point stores the first assigned data in the block link network by using a consensus mechanism.
Specifically, the first assigned data is stored in the blockchain network by the blockchain link point using a consensus mechanism, so that other blockchain link points in the blockchain network store the first assigned data.
Optionally, as shown in fig. 4, S505 provided in the embodiment of the present invention may specifically include S5051-S5052:
s5051, the block link node sends the first assigned data to a preset endorsement node in the block link network, so that the preset endorsement node confirms the first assigned data.
It should be noted that the preset endorsement node may be a supervision node of an operator, and if the block link node is allowed to store the first assigned data in the block link network, send the confirmation information to the block link node.
S5052, after receiving the confirmation information of the preset endorsement node, the block link point sends the first assigned data to a consensus node in the block chain network, so that the consensus node packages the first assigned data and broadcasts the first assigned data to other block chain nodes in the block chain network.
Optionally, in consideration that in some cases, the storage unit stores file data of an old version instantiated file in advance, and the blockchain network also stores registration information of the old version instantiated file, in order to update the file data of the old version instantiated file and prevent other NFVOs from tampering with existing assigned value data in the blockchain network, S505 provided in the embodiment of the present invention may specifically include S1 to S2:
s1, if second assigned data corresponding to the first instantiated file exist in the block chain network, determining whether the NFVO has the authority of modifying the first instantiated file by the block chain node.
Specifically, when the NFVO updates the existing second assigned data in the block chain network, the block chain node determines whether the NFVO has the authority to update the second assigned data.
In one implementation, determining whether the NFVO has the right to modify the first instantiated file may specifically include: if the target identification code corresponding to the second assigned data is generated by the NFVO, the NFVO has a right to modify the first instantiated file.
S2, if the NFVO has the right of modifying the first instantiation file, the block chain node updates the second assignment data into the first assignment data.
Specifically, the block link node updates the second assigned data stored in the node to the first assigned data, and stores the first assigned data in the block link network, so that other block link nodes in the block link network update the second assigned data to the first assigned data.
It should be noted that the block link point updates the second assigned value data to the first assigned value data, which can refer to the above steps S5051-S5052, and details are not described here.
Since the instantiated file in the storage network element may be read, written, and modified many times, in order to ensure that the instantiated file in the storage network element is complete and real in the instantiation process, as shown in fig. 4, optionally, after S505 provided by the embodiment of the present invention, S506 to S509 may be further included:
s506, the MANO network element inquires a download link and a first hash value in the first assigned data from the block link network according to the target identification code.
Specifically, after acquiring the first assigned value data from the blockchain network, the MANO network element analyzes the first assigned value data to acquire a download link and a first hash value in the first assigned value data.
And S507, the MANO network element acquires the target file data from the storage unit according to the download link.
And S508, the MANO network element generates a second hash value based on the hash algorithm according to the target file data.
S509, if the second hash value is matched with the first hash value, the MANO network element executes instantiation operation according to the target file data.
It should be noted that, if the second hash value does not match the first hash value, the instantiation operation is stopped.
In one implementation, if the MANO network element locally stores the file data of the target instantiation file in the instantiation operation, the MANO network element generates a second hash value based on a hash algorithm according to the locally stored file data, so as to verify the locally stored file data.
The embodiment of the invention provides a management method of a virtual network function, which is applied to a network function virtualization orchestrator NFVO, and comprises the following steps: acquiring registration information of a first instantiation file, sending the registration information to a block chain node, enabling the block chain node to generate first assigned value data according to the registration information, and storing the first assigned value data into a block chain network by using a consensus mechanism; by using the method, the registration information of the instantiated files can be sent to the block chain network, and an instantiated file directory for query can be formed, so that the global consistency management of the instantiated files is realized.
