Before describing the service configuration method, system, virtual Network element, and POTN device based on the virtual Network element provided in the embodiments of the present invention, it should be noted that a Packet enhanced Optical Transport Network (POTN) device is a unified cell intersection structure based on Optical channel data unit ODUk intersection, Optical channel data unit VC intersection, and Packet switching Packet intersection functions. In the prior art, in order to support the different services, the POTN device needs to configure a stack of a single-site multi-subrack, and a site may have various subrack forms, for example, there is a transmission subrack for implementing transmission of the service of the photoelectric layer; and the system is provided with a cross subrack which is used for realizing the switching and scheduling of service packets, and even a cluster expansion subrack and the like. In terms of hardware design, a station of the POTN equipment can manage 127 sub-frames at most, and the limitation and restriction of hardware are almost zero, but service configuration and scheduling of all station sub-frames of the POTN equipment are realized by controlling and managing all sub-frames of the whole station through a main control board of a main frame (any sub-frame configured in advance through a network manager) in the station of the POTN equipment, and with continuous access of new sub-frames and line cards, requirements on management capability and service processing capability of the main control board are higher and higher. Firstly, a large number of various network protocol processes need to be operated by newly adding a grouping supporting function; a plurality of interface adaptation works are required to be carried out on the main control board by the single board card compatible with the old platform architecture, and a plurality of message processing and distributing modules are additionally added. Secondly, configuration data and function queries sent by the control management server run on the main control board of the main subframe, so that the resource (processor/memory) occupation of the main control board is large, the processing performance of the main control board is affected, and the stability and reliability of the POTN equipment are further affected.
In order to solve the technical problem, embodiments of the present invention provide a service configuration method and system based on a virtual network element, and a POTN device. The service configuration method based on the virtual network element can be applied to a service configuration system based on the virtual network element, and the service configuration system based on the virtual network element comprises a control management server, the virtual network element and a first target subframe in a POTN equipment site.
The following describes, with reference to the accompanying drawings, an implementation principle and a process of a service configuration method based on a virtual network element according to some embodiments of the present invention. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic diagram of a service configuration system based on a virtual network element according to an embodiment of the present invention. As shown in fig. 1, the service configuration system 10 based on virtual network elements provided in this embodiment includes: the POTN equipment 12 site comprises at least one subrack; as can be seen from fig. 2, in the present embodiment, the POTN device 12 includes a subrack 1, a subrack 2. Illustratively, each subrack is composed of a group of sub-network elements with independent functions, and each sub-network element is managed by a respective network manager or by a unified network manager. On one hand, each sub-network element supports functions such as configuration and query of a single point service on a management plane (in this embodiment, a network manager corresponding to each sub-network element or a unified network manager, specifically, the network manager is not shown in fig. 1). On the other hand, each sub-network element also receives the service configuration command codes, which are sent by the control plane (in this embodiment, the control management server 11) and processed by the virtual network element 121, splits the service configuration command codes into board levels (for example, the line cards in fig. 2), and sends the board levels to a target board (one of the line cards) for execution.
As can be seen from fig. 2, a virtual network element 121 is provided on the subrack 1 of the POTN device 12. It should be noted that the virtual network element 121 may be preset on any subrack within the site of the POTN device 12. Further, among the various subracks within the site of the POTN apparatus 12 is a first target subrack 122. Correspondingly, the virtual network element 121 may be disposed on the first target sub-rack 122, or may be disposed on other sub-racks within the site of the POTN device 12 except for the first target sub-rack 122. That is, the first target sub-rack 122 may be the sub-rack 1 or other sub-racks other than the sub-rack 1. For example, as shown in fig. 2, in the present embodiment, the first target sub-frame 122 is a sub-frame 2.
As shown in fig. 2, each subrack of the POTN device 12 has the same logic module, for example, each subrack includes a management plane adaptation agent, a storage management model MIM, a unified device model UEM, a line card (also referred to as a single board), and the like. In this embodiment, each subrack of the POTN device 12 may be managed by one network management 123 as shown in fig. 2, or may be managed by each corresponding network management (not shown in fig. 2), and a QX channel and an interface of the subrack are provided between each subrack and the network management 123, where the specific format content of the QX is related to the type and version of the subnet in the corresponding subrack, which is not described in detail herein.
The control management server 11 is configured to send a service configuration request to the virtual network element 121, where the service configuration request includes a service configuration packet; the virtual network element 121 is configured to parse the service configuration packet to obtain a service information stream and a service configuration command code; the virtual network element 121 further determines a first target sub-frame 122 according to the service information stream, and sends the service configuration command code to the first target sub-frame 122, where the first target sub-frame 122 is a sub-frame used for processing a service corresponding to the service configuration command code in the site of the POTN device 12; the first target sub-shelf 122 is configured to determine a target board according to the service configuration command code, and process a service corresponding to the service configuration command code in the target board.
Illustratively, the functions of the control management server 11 may be implemented by software, and specifically, the central processor on the control management server 11 may perform corresponding operations; alternatively, the function of the control management server 11 may be implemented by an SDN controller running thereon, for example, the control management server 11 may issue a service configuration request to the virtual network element 121 through the SDN controller. The SDN controller has good expandability, and supports flexible scheduling functions of multiple regions of multiple manufacturers, cooperative control of end-to-end services, intelligent network operation and maintenance capacity and the like.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating an architecture of the virtual network element 121 in fig. 2. As the virtual network element 121 is arranged on any subrack in the site of the POTN device 12, instead of the main control board on the main subrack in the site of the POTN device 12 sending the service configuration command code to each subrack in the site of the POTN device 12, the virtual network element 121 and each subrack in the site of the POTN device 12 together form the POTN device 12, which can be specifically shown in fig. 2.
Furthermore, each subrack within the site of the POTN device 12 is similar to a server node, and the functions of the virtual network element 121 may be implemented by software on the subrack. Alternatively, the virtual network element 121 may be a software logic entity with an independent processing function, for example, the virtual network element 121 shown in fig. 3 includes a management plane adaptation agent 1211, referred to as agent, an optical network control module 1212, referred to as wasson, and a unified device model 1213, referred to as UEM. The management plane adaptation agent 1211 is configured to complete global configuration of the virtual network element 121 according to the network element attribute mode configured by the user, the IP, and the mask. Specifically, in this embodiment, the management plane adaptation agent 1211 completes the global configuration of the virtual network element 121 according to the host network element attribute mode, the IP address, and the mask address configured by the user, where the global configuration information of the virtual network element 121 includes network element information of each subrack in the POTN device site and the master-slave relationship between the virtual network element and all subracks.
The optical network control module 1212 is a module for automatically switching a transmission network, is configured to automatically select a route according to a service request dynamically initiated by a user or a network manager, and implements functions of establishing, modifying, and removing a service connection through signaling control, and is an optical transmission network integrating switching and transmission.
In this implementation, the unified device model 1213 is used to analyze the service configuration packet to obtain a service information stream and a service configuration command code, and is a core that forms the virtual network element 121, and can provide a unified management data abstraction and access interface for all application layers in the virtual network element 121, and is a unified data management center when the virtual network element 121 operates; further, a first target sub-rack 122 is determined according to the service information flow, and the service configuration command code is sent to the first target sub-rack 122, so as to instruct the first target sub-rack 122 to determine a target board according to the service configuration command code, and process a service corresponding to the service configuration command code in the target board.
As can be seen from the above analysis, in the service configuration system based on the virtual network element provided in this embodiment of the application, the virtual network element 121 preset on any one of the subframes in the station of the POTN device 12 is used to analyze the service configuration packet sent by the control management server 12, and then the first target subframe 122 is determined according to the service flow information and the service configuration command code obtained through the analysis, so that the configuration of the subframe service in the station of the POTN device through the virtual network element is realized, so that the main control board of the main subframe in the station of the POTN device does not need to configure the subframe service, the performance pressure of the main control board of the main subframe in the station of the POTN device can be relieved, and the stability and reliability of the POTN device are improved.
Exemplarily, as shown in fig. 4, fig. 4 is a schematic flowchart of an implementation flow of the service configuration method based on a virtual network element according to the embodiment of the present invention.
As shown in fig. 4, the service provisioning method based on the virtual network element includes steps S401 to S404. The details are as follows:
s401, the virtual network element receives a service configuration request sent by the control management server, wherein the service configuration request comprises a service configuration message.
In this embodiment, the control management server is a management and control plane of the POTN device, and the POTN device can be configured and maintained by the management and control plane. The control management server can provide basic management on the aspects of configuration, fault, performance and the like of the POTN equipment network system through the network management of each subrack in the POTN equipment. In addition, the control management server can also issue a service configuration request to the POTN equipment through internal software. For example, the SDN controller has good expandability, supports flexible scheduling functions of multiple manufacturers and multiple regions, and is generally used in a control management server for issuing a service configuration request to a POTN device, such as cooperative control of an end-to-end service, and intelligent network operation and maintenance capability. Specifically, in this implementation, the control management server sends a service configuration request to a virtual network element created in advance in the POTN device, and the virtual network element completes distribution and configuration of services of each site in the POTN device.
S402, the virtual network element analyzes the service configuration message to obtain a service information stream and a service configuration command code.
Illustratively, the virtual network element is composed of a set of software logic entities with independent functions, and may be deployed on a main control board of any sub-rack of the POTN device, for example, in this example, in a sub-rack 1 of the POTN device, the virtual network element may receive a global configuration of a management plane (e.g., a network manager) of the sub-rack on the virtual network element, and most importantly, configure an electrical/optical layer service sent by a control plane (e.g., a control management server through an SDN controller) in different sub-racks of the POTN device, so as to reduce a basic resource utilization rate of the main control board on a main sub-rack in the POTN device.
In an optional implementation manner, the virtual network element receives, through the management plane adaptation agent, a global configuration of the management plane to the virtual network element. Illustratively, the global configuration includes network element attribute configuration, IP configuration of the virtual network element communicating with the subnet element, mask configuration, site configuration, and the like. In addition, the creation of the virtual network element can be completed according to the global configuration.
In an optional implementation manner, the virtual network element performs service configuration on the electrical/optical layer service data sent under the control plane through a unified equipment model UEM. For example, the configuration data sent by the control management server includes an end-to-end service configuration message, where the service configuration message includes a service information stream and a service configuration command code; and the virtual network element analyzes the service configuration message through a Unified Equipment Model (UEM) to obtain the service information stream and the service configuration command code. The service information flow refers to a port path between line cards of the sub-network elements (network elements included in the sub-shelf), for example, which line card ports of another sub-network element go from a line card port of that sub-network element. The unified equipment model UEM is to find a line card port path through which a configuration message passes, and issue a service configuration command code to a corresponding line card, and the corresponding line card splits the service configuration command code into a sub-network element in which a target single board is located according to a target single board address contained in the service configuration command code to execute, so that the sub-network element loads and shares a message flow of service operation, and the basic resource utilization rate of a main control board is reduced.
S403, the virtual network element determines a first target sub-frame according to the service information stream, and sends the service configuration command code to the first target sub-frame, where the first target sub-frame is a sub-frame used in processing a service corresponding to the service configuration command code in the POTN device site.
In this embodiment, the network element information includes subframe information; the service information flow comprises sub-frame information on a service path; the subrack information includes a subrack number, the number of boards included in the subrack, a port number of the board, a service type supported by a board port, a connection condition between board ports, and the like.
Exemplarily, the determining, by the virtual network element, the first target sub-frame according to the traffic information flow may include: and the virtual network element matches the sub-frame information on the service path with the sub-frame information included in the summarized network element information to obtain the first target sub-frame.
In addition, in the embodiment of the present application, the service configuration command code includes an optical layer service configuration command code and an electrical layer service configuration command code; if the service configuration command code is an optical layer service configuration command code, the virtual network element determines a first target sub-rack according to the service information stream, and sends the service configuration command code to the first target sub-rack, which may include: and the virtual network element determines the first target sub-frame according to the service information flow, splits a target single board address according to the optical layer service configuration command code, and sends the target single board address to the first target sub-frame.
If the service configuration command code is an electrical layer service configuration command code; the virtual network element determines a first target sub-frame according to the service information stream, and sends the service configuration command code to the first target sub-frame, including: and the virtual network element determines the first target sub-frame according to the service information flow and sends the electrical layer service configuration command code to the first target sub-frame.
Optionally, the optical layer command code is generally a service between large network elements (in this embodiment, between sub-shelves) managed by a virtual network element, and the virtual network element parses an optical layer service configuration command code from an end-to-end service configuration packet, splits a command code of a single board granularity (line card) according to the optical layer service configuration command code, and assembles the command code of the single board granularity into a command list; wherein, the command code of the single board granularity comprises a target single board address.
Optionally, the electrical layer command code is generally a service between single network elements (in this embodiment, inside the subrack), and the virtual network element passes through the electrical layer service configuration command code parsed from the end-to-end service configuration packet to the first target subrack.
S404, the first target sub-frame determines a target single board according to the service configuration command code, and processes the service corresponding to the service configuration command code in the target single board.
Illustratively, the first target sub-rack receives an optical layer service configuration command code sent by a virtual network element, determines the target board according to a target board address included in the optical layer service configuration command code, and forwards the optical layer service configuration command code to the target board for processing.
Or, the first target subframe receives the electrical layer service configuration command code transparently transmitted by the virtual network element, determines the target single board according to the electrical layer service configuration command code, and forwards the electrical layer service configuration command code to the target single board for processing.
In addition, the determining, by the first target subframe, the target board according to the electrical layer service configuration code includes: the first target sub-frame splits the command code of the single board granularity from the electrical layer service configuration command code, wherein the command code of the single board granularity comprises a target single board address, and the target single board is determined according to the target single board address.
As can be seen from the above analysis, in the service configuration system based on the virtual network element provided in this embodiment of the application, the virtual network element 121 preset on any one of the subframes in the station of the POTN device 12 is used to analyze the service configuration packet sent by the control management server 12, and then the first target subframe 122 is determined according to the service flow information and the service configuration command code obtained through the analysis, so that the configuration of the subframe service in the station of the POTN device through the virtual network element is realized, so that the main control board of the main subframe in the station of the POTN device does not need to configure the subframe service, the performance pressure of the main control board in the station of the POTN device can be relieved, and the stability and reliability of the POTN device are improved.
Referring to fig. 5, fig. 5 is a schematic flowchart illustrating another implementation of the service configuration method based on a virtual network element according to an embodiment of the present invention. As shown in fig. 5, in this embodiment, compared with the embodiment shown in fig. 4, the specific implementation processes of S502 to S505 are the same as those of S401 to S404, except that S501 is further included before S502, which is detailed as follows:
s501, a second target sub-frame in the POTN equipment site responds to a host network element attribute mode, an IP and a mask configured by a user, a virtual network element is created in the second target sub-frame, the second target sub-frame is any sub-frame in the POTN equipment site, and network element information of each sub-frame in the POTN equipment site and master-slave relations between the virtual network element and all the sub-frames are stored in the virtual network element.
In an embodiment, a user may select in advance to create a virtual network element in a certain subframe in a station of the POTN device, for example, the user may select an attribute mode of the subframe in a network manager corresponding to the subframe, for example, the user is a host network element, the host network element may be on the same subframe as a main control board or the host network element and the main control board are not on the same subframe, and an IP and a mask code for communication between the host network element and the subnet element are configured by the network manager, and the virtual network element is created after the host network element corresponding to the POTN device receives the attribute mode, the IP and the mask code of the host network element configured by the user based on the network manager of the subframe. Specifically, referring to fig. 6, fig. 6 is a flowchart illustrating a specific implementation of S501 in fig. 5. As can be seen from fig. 6, S501 includes: sub-step S5011 to sub-step S5013. The details are as follows:
