Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms first, second and the like in the description and in the claims of the present invention are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the invention may be practiced other than those illustrated or described herein, and that the objects identified as "first," "second," etc. are generally a class of objects and do not limit the number of objects, e.g., a first object may be one or more. In addition, "and/or" in the specification means at least one of the connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.
In order to facilitate understanding of the present invention, the following is first explained.
In the embodiment of the present invention, a Transport Network (TN) forwarding layer may implement Transport Network slices with different isolation degrees through a Metro Transport Network (MTN) interface, an MTN channel, a Virtual Private Network (VPN), Quality of Service (QoS), and other mechanisms. For example, a transport network forwarding layer of the fifth Generation mobile communication technology (5th-Generation, 5G) may implement soft-slicing and hard-slicing through a combination of MTN interfaces, MTN channels, VPNs, and QoS mechanisms.
The MTN interface divides a physical Ethernet port into a plurality of Ethernet elastic hard pipelines based on time slot scheduling, so that the network interface layer performs service access based on time slots. The MTN channel is based on the interleaving technology of the 64/66B code block, and Time-Division Multiplexing (TDM) Time slot isolation is implemented in the interface and the device, thereby implementing extremely low forwarding delay and isolation effect. VPN and QoS isolation refers to implementing queue scheduling based on VPN technology and QoS to implement soft isolation.
In the embodiment of the present invention, a Slicing Packet Network (SPN) may virtualize a plurality of independent subnets from the same physical Network based on an MTN interface and an MTN channel technology, and each independent subnet allocates an independent Network resource, thereby implementing Service Level Agreement (SLA) isolation of a bearer Service in the independent subnet. The subnet may also be referred to as a logical subnet, a virtual network, etc. For example, as shown in fig. 1, the same SPN physical network element may be virtualized into multiple virtual nodes vNode, the same physical link may be virtualized into multiple virtual links vrink, and the SPN physical network may be virtualized into multiple logical subnets, such as vNet1, vNet2, and vNet3 in fig. 1.
In an embodiment of the present invention, a schematic diagram of an architecture of a slice deployment apparatus (or referred to as a slice deployment system) may be as shown in fig. 2. The Slice deployment device may include, but is not limited to, a Network Slice Management Function (NSMF), a Transport Network sub-Slice Management Function (TN-NSSMF), a Super Controller (SC), a Management and control body Domain Controller (DC), and the like. Where the DC is connected to the SPN network, the number of the DC may be multiple, such as the slice deployment device shown in fig. 2 including DC1 and DC 2.
It is understood that the NSMF, TN-NSSMF, SC and DC are logic components, and can be selectively combined in practical applications.
The deployment method of the transport network slice provided by the embodiment of the invention is described in detail by specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 3, fig. 3 is a flowchart of a method for deploying a transport network slice according to an embodiment of the present invention, where the method is applied to a slice deployment apparatus, and an architecture of the slice deployment apparatus may be as shown in fig. 2. As shown in fig. 3, the deployment method includes the following steps:
step 301: and acquiring a first transmission network service index of the target network slice.
Optionally, the first transport network service indicator may include at least one of: delay range, bandwidth, jitter, isolation, reliability, etc.
In one embodiment, after receiving a slicing service request from another service system, such as a Communication Service Management Function (CSMF), the NSMF in the slice deployment device disassembles the end-to-end service index to obtain a first transport network service index of the target network slice.
Step 302: and analyzing based on the first transmission network service index to obtain whether the stock slice meets the service requirement of the target network slice.
In this embodiment, the inventory slice may be understood as an inventory VPN, which represents a VPN to which logical resources and services have been allocated. For example, the analysis process of step 302 may be: judging whether the first transmission network service index meets a first condition, and determining that the stock slice meets the service requirement of the target network slice under the condition that the first transmission network service index meets the first condition, or determining that the stock slice does not meet the service requirement of the target network slice under the condition that the first transmission network service index does not meet the first condition. Wherein the first condition is a condition associated with the slice of inventory, such as a latency range requirement, a bandwidth requirement, and the like.
For another example, the analysis process of step 302 may be: and comparing and analyzing the first transmission network service index and the second transmission network service index of the stock slice to obtain whether the stock slice meets the service requirement of the target network slice. If the deviation of part or all indexes in the second transmission network service indexes and corresponding indexes in the first transmission network service indexes is within a preset range, determining that the stock slices meet the service requirements of the target network slices; otherwise, if the deviation between part or all of the second transmission network service indexes and the corresponding indexes in the first transmission network service indexes is not in the preset range, the stock slice can be determined not to meet the service requirement of the target network slice. Or if part or all of the second transmission network service indexes are superior to corresponding indexes in the first transmission network service indexes, determining that the stock slice meets the service requirement of the target network slice; otherwise, if part or all of the second transmission network service indexes are not better than the corresponding indexes in the first transmission network service indexes, the stock slice can be determined not to meet the service requirement of the target network slice.
Optionally, the second transport network service indicator may include at least one of the following: delay range, bandwidth, jitter, isolation, reliability, etc.
Step 303: under the condition that the stock slice meets the service requirement of a target network slice, obtaining the target network slice according to the stock slice; or, under the condition that the stock slice does not meet the service requirement of the target network slice, the target network slice is created according to the first transmission network service index and a preset slice subnet template.
The deployment method of the embodiment of the invention can obtain the first transmission network service index of the target network slice, and analyze based on the first transmission network service index to obtain whether the stock slice meets the service requirement of the target network slice, and under the condition that the stock slice meets the service requirement of the target network slice, the target network slice is obtained according to the stock slice, or under the condition that the stock slice does not meet the service requirement of the target network slice, the target network slice is created according to the first transmission network service index and a preset slice subnet template. Therefore, automatic deployment of the transmission network slices can be achieved, and slice deployment efficiency is improved.
Optionally, the above process of obtaining the target network slice according to the stock slice may include:
carrying out service index detection on the stock slice to obtain a second transmission network service index of the stock slice;
analyzing whether the second transmission network service index of the stock slice meets a preset condition or not;
under the condition that the second transmission network service index does not meet the preset condition, adjusting the second transmission network service index according to the first transmission network service index to obtain an adjusted stock slice, and determining the adjusted stock slice as the target network slice;
or, determining the stock slice as the target network slice when the second transport network service index meets a preset condition.
Thus, the target network slice can be obtained quickly and accurately based on the stock slice.
It is noted that the preset condition may be set based on actual requirements. For example, assuming that the first transport network traffic indicator of the target network slice includes a delay range a1, a bandwidth b1, a jitter value c1 and an isolation d1, the second transport network traffic indicator of a certain inventory slice includes a delay range a2, a bandwidth b2, a jitter value c2 and an isolation d2, and the inventory slice satisfies the traffic requirement of the target network slice, such as the deviation of the delay range a1 from the delay range a2 is within a preset range, the deviation of the bandwidth b1 from the bandwidth b2 is within a preset range, the deviation of the jitter value c1 from the jitter value c2 is within a preset range, but the deviation of the isolation d1 from the isolation d2 is not within a preset range, at this time, if the preset condition is that the deviations of all the second transport network traffic indicators from the corresponding indicators in the first transport network traffic indicators are within a preset range, the isolation of the inventory slice may be adjusted based on the isolation d1, so that the corresponding isolation deviation is within the preset range, and the service index of the transmission network of the adjusted stock slice meets the preset condition.
Optionally, the creating a target network slice according to the first transmission network service index and the preset slice subnet template may include: selecting a target sliced subnet template from the preset sliced subnet templates according to the first transmission network service index; and creating the target network slice according to the target slice subnet template. Therefore, by means of the preset slice subnet template, automatic network slice deployment can be achieved, and deployment efficiency is improved.
Optionally, the preset process of the sliced subnet template may include: firstly, dividing a slice packet network into a plurality of subnets, and configuring logic resources for each subnet; then, determining the service capacity of each sub-network according to the logic resource of each sub-network; and left and right, generating a slice subnet template according to the service capability of each subnet.
The present invention will be described in detail below with reference to the architectural diagram of the slice deployment system shown in fig. 2 and a specific embodiment thereof.
In the specific embodiment of the present invention, referring to fig. 4, the process of presetting the sliced subnet template may include the following steps:
step 401: the method comprises the steps of carrying out manual planning on an SPN physical network, carrying out network element division based on an MTN channel and an MTN interface, abstracting the same network element into a plurality of vNodes, abstracting the same physical link into a plurality of vLinks, and dividing the SPN network into a plurality of logical subnets based on different combinations of the vNodes and the vLinks, wherein different logical subnets are used for meeting different service requirements.
Step 402: on a control integrated domain controller DC, configuring an MTN interface and an MTN channel for SPN equipment based on a manually planned subnet division mode, and simultaneously performing subnet logic abstraction in the DC.
Step 403: and the DC calculates and analyzes the capability of each sub-network for providing the service, including the indexes of time delay range, isolation characteristic, bandwidth capability, service class of the transmission network and the like according to the logic resources of each sub-network, and generates a sliced sub-network template. Optionally, the sliced subnet template includes a subnet identifier ID, the service capability index, and an SPN network element and a port included in the sliced subnet template.
Step 404: the DC reports the generated sliced subnet template to the super controller SC.
Step 405: and the SC reports the generated slicing subnet template to the transmission network sub-slicing manager TN-NSSMF.
Step 406: the TN-NSSMF reports the slice subnet template to the end-to-end slice manager NSMF.
It should be noted that, if the slice subnet template is changed, the DC needs to generate a subnet template change notification to report to the SC, and the SC reports the change notification to TN-NSSMF, and then to report to the NSMF.
Referring to fig. 5, the preset process of the inventory slice business index in the embodiment of the present invention may include the following steps:
step 501: and the DC configures the InBandOAM aiming at the VPN storage service, and acquires all service indexes of the VPN, including characteristics of time delay, jitter, bandwidth utilization rate, packet loss rate and the like.
Step 502: and the DC reports the service index of the stock VPN to the SC.
Step 503: and the SC reports the service index of the stock VPN to the TN-NSSMF.
Step 504: and the TN-NSSMF reports the service index of the VPN stock to the NSMF.
It should be noted that, if the VPN inventory service index is changed, the DC needs to generate a change notification to report to the SC, and the SC reports the change notification to the TN-NSSMF and the TN-NSSMF to the NSMF.
Referring to fig. 6, a deployment process of a transport network slice in an embodiment of the present invention may include the following steps:
step 601: after receiving a slicing service request from another service system (such as CSMF, communication service management function), the NSMF disassembles an end-to-end service index, and splits the end-to-end service index into a wireless network, a transport network, and a core network service index, where the transport network service index includes: delay range, bandwidth, isolation, service type (such as L2VPN/L3VPN), subnet template ID (optional), transport network service type (optional), whether to multiplex the existing service (optional), service access network element, port and routing information, slicing subnet instance NSSI ID (optional), etc.
Step 602: the TN NSSMF carries out comparative analysis based on the service index in the message issued by the NSMF and analyzes whether the existing stock VPN, namely the stock slice service index can meet the service requirement. If yes, executing step 603, otherwise, executing step 608.
Step 603: the TN NSSMF analyzes whether adjustments to the inventory VPNs are required. Wherein if needed, step 604 is performed, otherwise, if not, step 607 is performed.
Step 604: the TN NSSMF issues a request to the SC to adjust for the inventory VPN.
Step 605: the SC issues a request to the DC to adjust for the inventory VPN.
Step 606: and after the DC is adjusted, reporting the SC, reporting TN-NSSMF by the SC, and reporting NSSI ID corresponding to the storage VPN to NSMF by the TN-NSSMF.
Step 607: and the TN-NSSMF reports the NSSI ID corresponding to the VPN stock to the NSMF.
Step 608: the TN-NSSMF analyzes the subnet template ID needed to be selected based on the upper layer service index, and issues VPN service creation request to SC, and the request may include subnet template ID, SPN network element, service access point and static route, bandwidth (such as CIR/PIR), basic protection information, etc.
Step 609: and the SC sends the total information of the service creation to the DC, wherein the total information at least comprises a subnet template ID, an SPN network element, a service access point, a static route, a bandwidth (CIR/PIR), detailed protection information, OAM (operation administration and maintenance) information, Qos (quality of service) information and the like.
Step 610: and the DC interacts with the SPN equipment based on the information issued by the SC, and establishes the VPN service based on the subnet template.
Step 611: and after the DC is created, informing the SC, returning the ID of the created VPN to the TN-NSSMF by the SC, and reporting the NSSI ID corresponding to the VPN to the NSMF by the TN-NSSMF to complete the creation of the transport network slice. The TN-NSSMF maintains a mapping of VPN IDs to NSSI IDs.
