Description

CDN network function virtualization management method, device and system
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for managing CDN network function virtualization.
Background
The content delivery network (Content Delivery Network, CDN) in the related art has been used for many years in the fields of internet audio and video transmission, IPTV network media transmission, and the like. The core idea of a CDN is to push content onto the service node closest to the user so that the user has access to the content nearby. The CDN is used for media transmission, so that the corresponding speed of a user for media content acquisition can be greatly improved, and the bandwidth pressure of media content transmission on a backbone network is also greatly reduced. In recent years, various services of the internet enter a high-speed development stage, the quality requirements for audio and video are continuously improved, and future 4k,8k, multi-view and VR (virtual reality) video are possibly the main contents transmitted on the network. In addition, the internet is also continually pushing various new services, many of which require the CDN to perform accelerated services. As a result, CDN networks are increasingly becoming an infrastructure for operators.
However, conventional CDNs have grown in defects in the face of newly developed services and upgrade service requirements. Conventional CDNs are generally chimney-type designs, which face a single service, and the capability of different CDNs cannot be shared, and solutions such as a converged service platform are also generated for this problem in recent years. Secondly, node equipment of the CDN is generally special equipment, upgrading and reconstruction of the equipment, migration of special software and the like are limited on the equipment, and the method is very unfavorable for new service deployment. In addition, when the CDN provider provides a service for a customer, only a dedicated node device can be deployed generally, but due to different requirements of the customer and different services, the utilization of software and hardware resources of the node device cannot obtain optimal efficiency. For CDN operators, nodes are required to be increased or reduced according to the requirement of more services, manual configuration is required, and timely and efficient installation and maintenance cannot be guaranteed. In actual network deployment, different provinces and different operators can deploy own CDN networks, the CDNs are interconnected, the service operation and the content distribution are in mutually independent states, and the mode of acquiring the same content is greatly limited for users. For content providers, content distribution is also limited by different channels, which greatly increases the cost of content distribution.
From the network level, the location of conventional CDN nodes, and in particular edge nodes, is typically at the edge of the core network, and the arrival of content data at the user terminal also requires the convergence layer and the access layer. From the future video service development, the bandwidth requirement of the existing CDN edge node cannot meet the development requirement of the future video service, but the number of the needed nodes is increased by sinking the CDN node into the carrier network, but the interaction operation to be processed is also more refined, the deployment of physical devices is definitely required to increase a great deal of labor cost and equipment cost, and the deployment position and scale have great influence on the existing CDN network topology. In the case of the underlying transport network, the CDN is not logically aware of the underlying network, and therefore, the CDN cannot perceive the situation of the underlying network, so that there is a situation that the bandwidth utilization is not high in the path planning of the data transmission. However, due to the development of the technology of the underlying network in recent years, the capability of the underlying network is gradually opened, and it is also possible for the CDN to probe the situation of the underlying network, which also affects the design thought of the future CDN network.
In view of the above problems in the related art, no effective solution has been found yet.

Example 3
This embodiment is an alternative embodiment according to this embodiment, and is used to make detailed and supplementary descriptions of the present application in conjunction with specific examples:
by means of virtualization, deployment of CDN virtual functions on a general physical device is an important evolution direction in the future. Network function virtualization (NFV-network function virtualization) and software defined networking (SDN-software defined network) are two network evolution technologies that are currently popular. NFV is a virtualization technology that simulates some network elements in a traditional network to a dedicated virtual machine (VM-virtual machine), and implements the functions of the original network elements in a software manner.
The network devices in the related art are relatively fixed in performance, and once they are occupied by CDN nodes, the network resources thereof are difficult to adjust, and the efficiency in terms of efficient use performance is poor. Such as insufficient bandwidth resource utilization, and the path cannot be dynamically adjusted when the network is congested. The SDN uses a dedicated SDN protocol to perform overall arrangement on nodes of the entire network (nodes supporting the SDN), so that data can be forwarded with optimal efficiency all the time in the forwarding process, and in addition, resources of the network can be dynamically arranged and adjusted, so that the utilization efficiency of network resources is greatly improved.
The embodiment provides a method and a system for realizing node function virtualization and deployment of a CDN supporting an SDN controller of a third party by utilizing a network function virtualization technology, so as to at least solve the problem that the CDN cannot perform optimal configuration and dynamic adjustment on resources of a bottom network when in virtualization creation and deployment in the related art.
According to one aspect of the present embodiment, there is provided a network function virtualization management server (MANO) capable of accepting a service request instruction from a content distribution network operation support system (Business Support System, BSS) or a service support system (Operation Support System, OSS) and generating necessary virtualization function modules supporting normal operation of a service according to service description information.
Further, the network function virtualization management server (MANO) is capable of analyzing a request instruction from the content delivery network operation and maintenance system, and arranging and managing necessary CDN node software logic modules and resources required for supporting the CDN node software logic modules according to the instruction.
Further, the network function virtualization management server (MANO) needs to support the north interface function of the SDN so as to communicate with the SDN control plane. The function supporting the north interface of the SDN refers to that the internal function of the MANO system needs to be embedded with an API of the north interface of the SDN or is realized through an external interface machine.
Further, the network function virtualization management server (MANO) can send resource arrangement information required by the software logic module supporting the virtualization to the resource virtualization platform for resource application and reservation.
Further, the MANO can utilize the logical resource allocation planned by the network function virtualization management server to call the logical resource from the resource virtualization platform, and instantiate the required (center node/edge node) logical function of the CDN into the form of application software to run on a Virtual Machine (VM).
Further, the MANO can support maintenance and management of lifecycle of the generated virtualized CDN application software.
According to another aspect of the present embodiment, there is also provided a resource virtualization platform (NFVI). The resource virtualization platform consists of one or more servers, can collect all physical service resources controllable in the whole network, virtualizes the physical service resources into virtual logic service resources, and can be discovered and called for allocation by a network function virtualization management server. The physical resources include software resources and/or hardware resources of the physical device. The software resources and/or hardware resources include at least computing resources and/or storage resources and/or network resources such as storage devices, network routers, switches, gateways, virtual machine servers, and application software and operating systems running on these devices.
In accordance with another aspect of the present embodiment, there is also provided a virtual CDN application software program and related application manager (EM). The application management program maintains and configures the business logic functions of the CDN software. In practical applications, EM may accept system service instructions from OSS/BSS to adjust the service functions of CDN application software.
The CDN node software logic module includes, but is not limited to: the system comprises a (central node) content preprocessing module, a content injection module, a content distribution module, a node service load balancing module (routing module), a storage/cache module and an operation and maintenance management module. The system comprises a (edge node) content service module, a service control module, a node business load balancing module (routing module), a storage/cache module, a content processing module and an operation and maintenance management module.
Furthermore, in addition to the logical functions of the CDN nodes, the functions APP of a logical network device, such as virtual switches and routers, may be virtualized. The application capabilities of the switch and router can be dynamically adjusted as needed.
Further, the virtual CDN nodes may implement the functionality of a standard SDN northbound interface so that after creation, communication with SDN controllers of third parties may continue.
Further, if a standard SDN north interface protocol is not used between the CDN node service function and the SDN control plane, the CDN node is not considered an SDN APP. At this time, a VNF of another SDN APP needs to be virtualized, where the VNF implements an SDN northbound interface supporting a standard, and functions to implement repackaging of communication content from the CDN to the VNF into content of an SDN northbound interface communication protocol. The communication protocol between the VNF and CDN node functions may use a proprietary protocol.
According to another aspect of the present embodiment, there is also provided an SDN controller (SDN controller) of a third party. The third party SDN controller is an SDN controller with a development function which operates outside the virtual CDN operation environment and can communicate with the third party SDN controller through a standard SDN northbound interface. The functional structure of the SDN controller of the third party does not fall within the scope of this embodiment.

Further, if the GSLB needs to be able to directly issue resource changes or orchestration instructions to the MANO system, the GSLB is required to implement an os-ma interface with the MANO system.
According to another aspect of the present embodiment, there is also provided a node function virtualization and deployment method for implementing a content distribution network using a network function virtualization technology, including: the MANO system performs planning and arrangement of the computing capacity and the storage capacity of the target node according to the service requirement of the CDN, and performs application and reservation of resources on the virtualized resource platform according to the arranged resource requirement. The MANO system requests the needed network resources from the SDN controller of the third party and reserves the needed network resources. And virtualizing the functions of the CDN target nodes by using all the applied resources, and updating the node information after the virtualization on an operation and maintenance system and a global load balancing server of the CDN.

Step S5, the same as above
Fig. 10 is a schematic diagram of a logic function architecture of an SDN controller supporting a third party and a virtual CDN node according to the present embodiment, and as shown in fig. 10, the main logic function of the virtual CDN node is an SDN virtual network device mainly composed of software (VNF) running on one or more Virtual Machines (VMs). While the SDN controller of the third party is located outside the operating environment of the virtual system and in an independent SDN operating domain, fig. 10 shows each functional module and its interrelation, including:
1) The native CDN service system comprises an operation and maintenance management platform (OSS/BSS), wherein the network management function is also included in the operation and maintenance system.
2) The load balancing system (also called as a routing system) has the main functions of monitoring the state of servers in the whole network, balancing the load of service routing and providing the final service CDN node address for users.
The GSLB and OSS/BSS platforms may use the existing CDN system scheme, but require an interface for adding and virtualizing a system, for example, an NFV system, and an OS-MA interface needs to be implemented. For example, in implementation, the GSLB may directly send a network bandwidth change request to the MANO, or may perform load balancing interaction with a virtual CDN node on a virtual application platform. These interfaces may be interfaces that emulate traditional CDN nodes, or interfaces with SLB agents on virtual CDN nodes. As to which interface is implemented, it is up to the designer to decide.
After node virtualization, the operation and maintenance of the virtual node can still adopt an original operation and maintenance management interface, which is mainly used for changing and configuring the service logic of the virtual node, and the management of the life cycle of the node is managed by a MANO system.
3) A service virtualization system comprising 3 functions: network function virtualization Management Servers (MANOs), resource virtualization platforms, and application service management. Wherein the MANO can be further divided into a resource orchestration manager, a virtual application (and manager), and a virtual resource manager. The specific roles of the functions have been set forth above.
Wherein MANO needs to explicitly support SDN northbound interface. Further, the function of supporting the north interface of the SDN refers to that the internal function of the MANO system needs to be embedded with an API of the north interface of the SDN, or is implemented by an external interface machine.
The VNF APP is mainly used as an instantiation container of the virtual CDN node logic function, and the virtual CDN node completed function is mainly a copied CDN node logic function and is divided into a center node and an edge node.
4) The main function of the third party SDN controller is to arrange network resources for the nodes of the CDN according to the requirements, for example, reserve the downlink bandwidth of 10G and arrange and discharge the end-to-end routing path.
Fig. 11 is a diagram of physical networking of virtual CDN nodes and virtual SDN controllers in a transport network, where in fig. 11, an actual CDN networking architecture is shown, and a CDN center node, edge nodes, and user terminals are linked to each other by a transport network, where the transport network is actually composed of a large number of routing and forwarding devices, such as routers and switches.
In the conventional CDN architecture, the underlying transport network is unknown, so that the data transmission in the conventional CDN network cannot be controlled by the CDN. The data in the network generally causes degradation of transmission quality due to problems such as poor network link, network congestion, etc. In fig. 11, an SDN controller of a third party and a virtual CDN edge node are added. Under the requirement that the CDN node needs to be virtualized to increase the coverage of the CDN node and the network bandwidth is adjusted, a virtual CDN node is created and is accessed to the original transmission network through a virtual router node.
However, the vcn node cannot control the network devices in the transport network due to the imperceptible nature of the underlying network to the CDN. The entire virtual CDN system cannot route the underlying network (or in other scenarios, the network devices in the partial transport network are not included in the controllable range of the network resource pool of the vcn system). Therefore, in the creation process, virtual router nodes which are compiled and exhausted in the network by means of the SDN controller of the third party are required to provide required bandwidths and transmission paths for the virtual nodes, and more virtual routers can be created for CDN nodes through adjustment of subsequent services, or the most suitable routing paths are dynamically selected in the transmission paths between CDN edge nodes and user terminals.
Fig. 12 is a logic flow diagram supporting CDN node virtualization of a virtual SDN controller according to the present embodiment, including:
step 101: the OSS/BSS system of the CDN receives the instruction from the external system and converts the instruction into a service instruction for the MANO system, for example, "open CDN function for operator a and reserve 10G transmission bandwidth. "instructions containing specific requirements, such as" open center node (forwarding function, routing function, caching function) ". "
Remarks: the service instruction for the MANO can be sent by the GSLB system through an OSS/BSS system, or can be directly sent by the GSLB system to the MANO system.
Step 102: after receiving the service opening instruction sent by the OSS/BSS, the MANO system performs resource arrangement of the virtual CDN nodes according to service requirements in the service opening instruction, including arrangement on demand (VNF custom templates), or arrangement according to a default template. For example, an "edge node" contains several functional blocks of "media service function", "media routing function", "media control function", where 5000 concurrent processing capabilities of computing power, 100G transmission bandwidth, and 10T storage space are required. The MANO system generates these capability orchestrations into different (computing, storage, network) resource application instructions.
Step 103: the MANO system sends compute and store resource orchestration requests to a resource virtualization platform (NFVI)
Step 104: NFVI allocates and reserves resources to be calculated and stored
Step 105: NFVI feeds back reserved resource information to MANO
Step 106: the MANO applies for orchestration of network resources to the SDN controllers of the third parties.
Step 107: the SDN controller performs resource arrangement and reservation on the controllable network equipment, and feeds back information to the MANO.
Step 108: and the MANO combines the acquired calculation, stores, and the network resource instantiates the CDN node function according to the VNF template to create the VNF APP of the CDN.
Step 109: and generating virtual CDN nodes, and feeding information back to the MANO.
Step 110: the MANO receives the node generation information and maintains the node information. Meanwhile, the node information is fed back to an OSS/BSS system and/or a GLSB system.
Step 117: the OSS/BSS system sends the newly generated node information to the GSLB system, and the GSLB system updates the node information, the network topology and the content routing table which are maintained internally. If the configuration of the node service logic parameters is needed, the EM configures the parameters of the CDN node virtualization software according to the service parameter configuration information. The service parameters may be obtained by the OSS/BSS system or by a predefined VNF template.
It should be noted that in the foregoing description, the step of generating the CDN node and the step of generating the SDN controller may be exchanged in actual operation, that is, after the CDN node is generated first, network resources required by the CDN node may be reserved by the SDN controller generated later. Or the CDN node APP and the SDN controller APP are communicated internally to complete the arrangement of network resources.
