Background

With the development of information technology, conventional communication mechanisms have failed to meet the demands of emerging applications.

Although there have been some studies on deterministic communication services, there are still many problems to be further discussed. The method comprises the following steps: a) Network latency and latency jitter cannot meet the requirements of certain application scenarios, for example, the period of industrial automation control can be reduced from "100" milliseconds to less than "1" milliseconds; under a mobile robot cooperative driving scene, the packet delay requirement is less than 10 milliseconds, and the packet delay jitter is less than 25 percent; and b) the robustness of the system is insufficient, and when certain nodes are congested or interrupted, delay jitter and packet loss phenomenon can occur in deterministic traffic, and in this case, the robustness of the system needs to be enhanced.

Detailed Description

Other advantages and effects of the present invention will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present invention with reference to specific examples. The invention may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present invention. It should be noted that the following embodiments and features in the embodiments may be combined with each other without conflict.

It should be noted that the illustrations provided in the following embodiments merely illustrate the basic concept of the present invention by way of illustration, and only the components related to the present invention are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complicated.

With the explosive growth of network demands, conventional host-centric network architectures will have difficulty meeting current demands for network quality of service. For this purpose, information-centric networking (ICN) is proposed as a new network architecture. In ICN networks, in this regard, content information required by the user is often stored in memory at the edge of the network. The ICN can realize the functions of separating content from position, internally-arranged caching and the like, thereby better meeting the requirements of large-scale network content distribution, mobile content access, network flow balance and the like.

Information center networks are attracting attention from researchers in various countries as an important form of future networks. With the continuous perfection and development of wireless communication technology, ICN-supported wireless networks are particularly important. However, the current network architecture cannot well meet the requirement of the emerging application on the time delay, and considering that deploying a unified network in a full scene increases the burden of network transmission, the deployment of the ICN needs to be designed in a lightweight way for specific services, so that it is necessary to specially design for each service to enhance the network capability of the ICN. For deterministic communication services, it is desirable to highlight features such as strong robustness, ultra-low latency, and bounded jitter when deploying a network.

For deterministic communication services, the characteristics of strong robustness, low time delay, bounded jitter and the like are required to be highlighted when a network is deployed. Unlike deterministic communication services provided by conventional network architecture, ICN, as an underlying network, will have some impact on deterministic communication services towards IMT-2030 in terms of providing lower latency, improving system robustness, enhancing routing path selection, etc. First, the packet delay is further reduced, wherein the ICN has in-network buffering and storage capabilities, so that the required data can be stored at the edge node, thereby reducing the number of hops for packet transmission. Meanwhile, a routing mechanism and security capability based on ICN names can also support quick data retrieval. And secondly, the robustness of the system is enhanced, wherein the redundancy backup data also improves the robustness of the system and reduces corresponding delay jitter. As a plurality of data backups can be cached in any edge node of the ICN, the probability of finding the file can be greatly improved as long as the position of the main backup file can be quickly searched in the forwarding node, thereby improving the robustness of the system. And efficient routing path selection. In-network data such as network states can also help edge nodes to perform data statistics and routing path computation, which can also help network nodes predict network states and optimize network resource allocation.

In particular, ICN has natural advantages as an underlying network for deterministic communication services. The ICN capability may be used to better support and optimize deterministic QoS. Thus, enhancing ICN to support deterministic communication services has natural architectural advantages, but at the same time faces many challenges. For the present application, firstly, the existing ICN network architecture needs to be specially designed and optimized to perfectly support and optimize the special requirements of deterministic communication services; secondly, aiming at the service requirements of specific scenes such as industrial Internet, the content placement method, signaling interaction and transmission mechanism are required to be redesigned to optimize the network performance, so that the established aim can be achieved.

The invention is directed to real-time control of industrial sites, smart grids, intelligent traffic and the like, and aims to provide ultra-low delay for real-time control services, and in a system, the invention provides a content placement, signaling, transmission mechanism and related network function architecture for real-time control in an information center network of an industrial internet, which is different from a transmission mode of a TCP/IP network, firstly, please refer to FIG. 1, in an embodiment of the invention, the information center network architecture 10 of the invention for the industrial internet specifically comprises:

a security layer 11, an application layer 12, a management layer 13, a control layer 14, and a data layer 15, wherein,

The control layer 14 at least comprises a time-frequency synchronization unit 141 and a buffer/aggregation copy unit 142, wherein the time-frequency synchronization unit 141 is used for ensuring that the information center network node synchronizes the time of the interest packet, and the buffer/aggregation copy unit 142 is used for ensuring that the data in the control command packet is successfully backed up;

The management layer 13 at least comprises an enhanced resource management unit 131, wherein the enhanced resource management unit 131 is used for ensuring that a data block is sent to a first hop information center network node and stored in the first hop information center network node;

the data layer 15 comprises at least an enhanced forwarding unit 151, wherein the enhanced forwarding unit 151 is configured to ensure that a data block is transmitted along an optimal path.

It should be noted that, in this embodiment, as shown in fig. 1, the present invention proposes an enhanced ICN network function architecture, on the basis of the conventional ICN network architecture, by enhancing the ICN network architecture, a part of function modules are added/modified, each function module has a positive effect on information forwarding of the industrial internet, and accordingly, as shown in fig. 1, for the security layer 11 in this embodiment, specifically, the access control unit 111, the naming authentication unit 112, the data integrity verification unit 113 are included, the application layer 12 directly applies, the management layer 13 further includes the performance management unit 132, the fault management unit 133, the configuration management unit 134, the account management unit 135 and the security management unit 136, the control layer 14 further includes the routing unit 143, the mobility support unit 144, the publish/subscribe unit 145 and the forwarding information base 146, and the data layer 15 further includes the cache unit 152, the application layer definition unit 153 and the data 154.

Specifically, for the management layer 13, the ICN needs to be considered to manage and schedule the computing resources, the storage resources and the network resources, so that the invention innovatively designs the enhanced resource management unit 131 on the basis of the traditional ICN network architecture to strengthen the resource management function, and is specifically used for managing and scheduling the resources in the network, such as the computing resources, the storage resources, the network communication resources and the like, wherein the storage and the computing resources help the node to calculate a proper routing path, and then the node schedules the network communication resources according to the derived routing path, thereby being beneficial to reducing network interruption and congestion and ensuring the stability and the reliability of the network.

Meanwhile, for the control layer 14, the ICN should consider the capability of supporting high-precision scheduling, cache backup aggregation and cache replication, including time/frequency synchronization and cache aggregation/replication, so that the invention innovatively designs the time-frequency synchronization unit 141 and the cache/aggregation replication unit 142 on the basis of the traditional ICN network architecture, wherein the time/frequency synchronization can help each node to obtain consistent time consciousness in high-precision time synchronization, thereby providing high-precision time proofreading capability for each service node and facilitating a scheduling mechanism; and the buffer aggregation/replication can improve the robustness of the system by using the redundant backup data, and reduce the corresponding delay jitter. Conversely, too much redundant backup data can also introduce complexity into finding the desired data.

Further, for the data layer 15, ICN supporting effective path selection, queue scheduling, file request aggregation/replication and the like should be considered, so the present invention innovatively designs the enhanced forwarding unit 151 based on the traditional ICN network architecture, where the enhanced forwarding function specifically includes a forwarding function based on an NDO name, a request aggregation/replication function, a traffic shaping function, a queue scheduling function, a label parsing function, and a message forwarding loop avoidance function, which enhances efficiency of data processing and transmission, and enhances robustness of the network, where NDO (NAMED DATA obiects) is a data block.

Specifically, referring to fig. 2, a schematic view of an application scenario of the present invention for controlling an information center network facing an industrial internet is shown, where the information center network architecture 10 facing an industrial internet provided by the present invention is used as a bottom layer network, in an industrial internet real-time control scenario, lower delay is provided, robustness of a system is improved, routing path selection is enhanced, etc., where an ICN operation mechanism is described, and in an ICN network, a memory of a base station includes three data structures: a pending interest Table (PIT, pending Interest Table), a forwarding information Table (FIB, forwarding Information Base) and a Content cache (CS, content Store) to decide whether, when and where to forward each interest packet, wherein the PIT stores all interest packets forwarded by the router but not yet satisfied, and each PIT entry records the data name carried in the interest packet, and an ingress interface and an egress interface.

When the interest packet of the user arrives, the ICN router firstly checks whether the content cache has matching data, and if so, the router returns a data packet on an interface where the interest packet arrives. Otherwise, the router looks up the name in the PIT, and if a matching entry exists, the entry simply records the interest package-in-interface. If there is no matching PIT entry, the router will forward the interest packet to MBSs based on the information in the FIB and the adaptive forwarding policy in the router (if there is no corresponding data in the MBS, the interest packet is forwarded to the content producer located in the core network). When a router receives interest packets of the same name from multiple downstream nodes, it forwards only the first interest packet upstream to the data producer, and the FIB itself is populated with a routing protocol based on name prefixes, each having multiple egress interfaces.

Specifically, in an embodiment of the invention, the method for controlling an information center network facing to an industrial internet of the present invention includes the following steps:

Step S302, obtaining an interest packet sent by a user terminal, wherein the interest packet specifically comprises a slice service type interest packet, and the slice service type interest packet at least comprises a forwarding priority identifier;

step S304, identifying a designated routing path to request the interest packet based on a table stored in the information center network node to obtain a data block;

step S306, the data block is returned to the user terminal and a control command packet fed back by the user terminal is obtained, wherein the control command packet at least comprises a control signaling priority identifier;

Step S308, retrieving the information center network node in real time based on the control command packet to identify a target control command, and transmitting the target control command to a target industrial device.

It should be noted that, in this embodiment, when the interest packet requests from each information center network node, a preset time-frequency synchronization unit is used to synchronize the time of the interest packet; when the data block is returned to the user terminal, a preset enhanced resource management unit and a preset enhanced forwarding unit are utilized to identify the transmission path of the current data block, and when the information center network node is searched in real time based on the control command packet to identify a target control command, a preset caching/aggregation copying unit is utilized to backup the data in the control command packet.

Specifically, as shown in fig. 4, the data structure of the slice service type interest packet is shown, where the slice service type interest packet includes a forwarding priority identifier, in this embodiment, the forwarding priority identifier is correspondingly added, and by adding the forwarding priority identifier, the ICN node determines the priority of the forwarding sequence according to the time sensitivity classification in the interest packet, where the time sensitive service is to be given a high priority, and accordingly, when the slice service type interest packet proposed in this embodiment is named, the following form may be presented: priority = email/sensor-data/device 01/20230307/0900.

Further, in an embodiment of the present invention, the method further includes naming the data block according to a predetermined data format, where the naming content includes a first hop information hub node.

In this embodiment, the data block (NDOs) is named according to a predetermined data format, for example, the data block is/industrial/device 01/partition/20230307/0830, and is subjected to enhanced resource management by an enhanced resource management unit, and is effectively sent to the first-hop ICN node (ICN ELEMENT) and then stored in the first-hop ICN node, and thereafter, scheduling storage and calculation resources can be effectively allocated according to the requirement of the network, and the newly generated NDO can be distributed to the ICN node having a storage function in the network.

Further, in an embodiment of the invention, as shown in fig. 5, the step of identifying a designated routing path based on the table stored in the information center network node to make the request of the interest packet to obtain a data block specifically includes the following steps:

Step S502, the appointed route path is obtained based on the FIB table stored by the information center network node;

Step S504, requesting at each information center network node along the specified routing path to obtain the data block, where the information center network node classifies the data block according to the forwarding priority identifier in the interest packet, so as to determine the forwarding sequence of the current information center network node to the interest packet.

In this embodiment, the information center network node (ICN) stores an FIB table in advance, and a designated routing path is corresponding to the FIB table, so that the designated routing path can be identified based on the FIB table stored in the information center network node, and then, when the ICN nodes request along the designated routing path, each ICN node performs hierarchical forwarding according to a forwarding priority identifier corresponding to a slice service type interest packet, so as to ensure that a time sensitive interest packet is given a high priority.

Further, in an embodiment of the present invention, the data block is returned to the user side along the optimal path, and the data block is stored in a specific node on the optimal path.

In this embodiment, it should be noted that, since the foregoing embodiment illustrates that, in the network structure provided by the present invention, the data layer 15 includes at least the enhanced forwarding unit 151, the enhanced forwarding unit 151 may be used to ensure that the data block can be transmitted along an optimal path when returned to the user terminal or the control terminal, and meanwhile, a specific node having a storage function exists on the optimal path, and NDO may be stored on the corresponding node.

Further, in an embodiment of the present invention, the real-time searching of the information center network node based on the control command packet to identify a target control command specifically includes the following steps:

step S602, identifying the control signaling priority identifier based on the acquired control command packet;

Step S606, forwarding the control command packet hop by hop along the optimal path, and performing hierarchical forwarding at each information center network node based on the control signaling priority identifier.

It should be noted that, in this embodiment, after a data block is requested, the data block is returned to a user side and a control command packet fed back by the user side is obtained, where, as shown in fig. 7, the data structure of the control command packet is displayed, when the information center network node is searched in real time based on the control command packet to identify a target control command, firstly, the control command packet is identified based on the obtained control command packet, then, the control command packet is forwarded hop by hop along the optimal path, that is, continuously, the real-time search is performed to a higher node, and by identifying the control command priority identifier in a data packet prefix, the data packet is correspondingly referred to as a control command priority identifier in this embodiment, so that hierarchical forwarding can be performed at each information center network node based on the control command priority identifier, accordingly, the control command priority identifier is also time-sensitive data, when forwarding the control command packet, the ICN node can be forwarded preferentially, and accordingly, when the name of the control command packet is set in the data packet is given by the following name, and the name of the user may be given as follows: the control-command/priority=email/json/priority=60 min/device01/stop-process/20230307/0920, in combination with the cache/aggregate copy unit 142 described in the foregoing embodiment, the cache copy/aggregate function corresponding to the unit ensures that the data block of the control command is reasonably and redundantly backed up, which helps to improve the efficiency and response speed of the ICN network, enhance the robustness of the system, and finally, when the command in the control command packet is transferred to the corresponding industrial device, the industrial device can start executing the corresponding control command.
