The Memory 1005 may be a Random Access Memory (RAM) or a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of a synchronous ethernet-based destruction apparatus and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a synchronous ethernet-based destruction program.
In the synchronous ethernet-based destruction device shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 of the damage apparatus based on synchronous ethernet according to the present invention may be disposed in the damage apparatus based on synchronous ethernet, and the damage apparatus based on synchronous ethernet calls the damage program based on synchronous ethernet stored in the memory 1005 through the processor 1001, and executes the damage method based on synchronous ethernet provided in the embodiment of the present invention.
An embodiment of the present invention provides a method for breaking a ring based on a synchronous ethernet, and referring to fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of a method for breaking a ring based on a synchronous ethernet according to the present invention.
In this embodiment, the method for breaking a synchronous ethernet-based network includes the following steps:
step S10: when the source communication node and the target clock source in the communication network are detected to be disconnected in communication, the hop count change of the extended clock synchronous message in the data transmission process in the communication network is predicted, and the target hop count is obtained.
It should be noted that, in the embodiment, the execution subject of the method may be a device having functions of data transmission, data acquisition and data processing, for example: the present embodiment does not specifically limit the present invention, and in the present embodiment and the following embodiments, a server that controls a communication network to perform time synchronization will be taken as an example for description.
It should be noted that the communication network refers to a network node set used for various data communication purposes, wherein the network structure includes: in the present embodiment, the operation of breaking the network structure including the ring network is mainly performed.
In a specific implementation, a source communication node refers to a first communication node connected to an external signal source in a communication network structure, referring to fig. 3, in fig. 3, taking a time synchronization technology of a communication network as an example, in the communication network structure, a node a is a first communication node connected to a GPS signal source or a beidou signal source in the communication network and is denoted as a source communication node, where each communication node in the communication network also has a setting of a Synchronization Status Messaging (SSM) level when performing data transmission, so as to determine whether a frequency signal level corresponding to transmitted data meets a standard in a network clock synchronization process, and when meeting the standard, perform data communication.
In addition, the local SSM level of each communication node of the communication network is 0xB, and when data transmission is performed, the SSM level of 0xB needs to be converted into the SSM level of 0x2, and the lower the value corresponding to the level, the higher the priority.
It should be understood that, the target clock source is used to provide a signal source of the clock synchronization signal for the communication network, and according to different time synchronization technologies, the target clock source may be a GPS signal source or a beidou signal source, or may be another signal source that can provide the clock synchronization signal, which is not limited in this embodiment.
It can be understood that the extended clock Synchronization packet is a clock Synchronization packet obtained by modifying a packet format and a data format based on a standard clock Synchronization packet (ESMC), where the packet format and the data format of the standard clock Synchronization packet refer to fig. 4 and 5, and the packet format and the data format of the extended clock Synchronization packet refer to fig. 6 and 7, where the extended clock Synchronization packet increases clockdiversity and a masked parameter compared to the standard clock Synchronization packet, the clockdiversity identifies a clock ID, and the masked identifies a Synchronization hop count.
It should be noted that the target hop count refers to the number of communication nodes that are experienced in the communication network in the process of communication data reaching the target node based on the communication structure of the communication network, for example: in fig. 3, the target hop count of the extended clock synchronization packet transmitted from node a to node b is 1, and after the extended clock synchronization packet node b completes data transmission to the next communication node, the target hop count is 2, however, since the next communication node has two communication nodes, node c and node d, during the data transmission from node b to the next communication node, in this embodiment, when the target hop count is 2, two corresponding data transmission paths exist, which are: the data transmission path of the node a-NodeB-node c and the data transmission path of the node a-NodeB-node d are not specifically limited in this embodiment.
In the specific implementation, the process of predicting the hop count change of the spread clock synchronization packet in the data transmission process in the communication network is to update the cascoded character segment in the spread clock synchronization packet through the spread clock synchronization packet in the data transmission process, and every time the spread clock synchronization packet passes through one communication node, 1 is added to the corresponding cascoded character segment, that is, the synchronous hop count of the spread clock synchronization signal, and every time the spread clock synchronization packet passes through one communication node, 1 is added to the synchronous hop count.
In a specific implementation, referring to fig. 8, after the node a disconnects the clock signal source of the GPS/beidou, the node a updates that its SSM level is 0xB, continues to send an ESMC message to the node b, and after the node b receives the ESMC message of the node a, because the SSM level of the node b is 0x2, the node a is no longer tracked, and this process is marked as the first second; in the second, NodeB updates own SSM to be 0xB, and sends ESMC message to NodeC and NodeD, NodeC and NodeD can update own SSM to be 0xB only in the third second, and send ESMC message to outside, but in the second, because NodeE can continuously send ESMC message with SSM of 0x2 to NodeD, and at the moment, the SSM of NodeB is 0xB, then NodeD can switch synchronous route, and start to track NodeE, so actually starting from the 2 nd second, it will become NodeD to track NodeD, NodeC tracks NodeB again, NodeE tracks NodeC again, and forms synchronous loop, which can not be broken.
Step S20: and when the target hop count is greater than the preset hop count, controlling the communication network to discard the extended clock synchronization message and to select a clock source again.
It should be noted that the preset hop count may be set by the user, for example: 20 or 30 hops, etc., which is not specifically limited in this embodiment, the number of the communication nodes in the communication network is generally less than 20, and if more communication nodes are added, the difficulty of network establishment will be greatly increased, so that if the hop count in one communication network is greater than 20, it indicates that a synchronization loop is most likely to occur in the communication network, and in this embodiment, the preset hop count will be described as 20 hops.
In a specific implementation, the process of controlling the communication network to discard the extended clock synchronization packet and performing clock source selection again may be: and sending a control instruction to each communication node in the communication network so that each communication node in the communication network discards the extended clock synchronization message according to the control instruction, prohibits the data transmission of the extended clock synchronization message, keeps silent, waits for the clock signal source to be switched on again, and reestablishes the time synchronization process.
Further, the step S20 includes:
detecting whether a message node list corresponding to the synchronous Ethernet is an empty set;
if not, controlling each communication node in the synchronous Ethernet to discard the extended clock synchronous message;
acquiring frequency quality grade, priority information and node hop count information of each communication node;
and selecting a clock source again according to the frequency quality grade, the priority information and the node hop count information.
It should be noted that the message node list refers to all communication nodes in the communication network that receive the extended ESMC message, so as to subsequently control the communication nodes to discard the extended ESMC message, thereby entering a silent state, facilitating subsequent signal source selection, and simultaneously disconnecting clock synchronization to complete destruction of the synchronous ethernet.
In this embodiment, when the node hop count in the communication network exceeds a set threshold, it is determined that network looping exists in the communication network, and at this time, each communication node is controlled to discard an extended clock packet and control each communication node to reset its own SSM level, and a step of reselecting a signal source is entered.
The embodiment discloses a method for destroying a synchronous Ethernet, which comprises the following steps: when detecting that a source communication node in a communication network is disconnected from a target clock source, predicting hop count change of an extended clock synchronization message in a data transmission process in the communication network to obtain a target hop count; when the target hop count is greater than the preset hop count, controlling the communication network to discard the extended clock synchronization message and to select a clock source again, in the embodiment, performing data communication in the communication network through the extended clock synchronization message to record the hop count of the extended clock synchronization message, implementing monitoring on a data transmission process, predicting hop count change of the extended clock synchronization message in the data transmission process in the communication network to obtain the target hop count, judging that the communication network has network looping when the target hop count is greater than a preset hop count threshold value, wherein the network communication is influenced, discarding the extended clock synchronization message through the control communication network, and selecting the clock source again to realize ring breaking based on the synchronous Ethernet, reselecting a source, and performing network communication again, so that the situation that the Ethernet in the prior art performs data communication is avoided, the technical problem that data communication cannot be carried out due to network loop forming is solved, and the communication efficiency is improved.
Referring to fig. 9, fig. 9 is a flowchart illustrating a second embodiment of a method for breaking a synchronous ethernet-based link according to the present invention.
Based on the first embodiment, in this embodiment, before the step S10, the method further includes:
step S01: and controlling a source communication node in the communication network to generate an extended clock synchronization message.
It should be noted that the extended clock synchronization packet is a clock synchronization packet obtained by modifying a packet format and a data format based on a standard clock synchronization packet, and the extended clock synchronization packet increases clockproperty and casoded parameters compared with the standard clock synchronization packet, where clockproperty identifies a clock ID and casoded identifies a synchronization hop count.
Further, in order to obtain the spread clock synchronization packet, the step S01 includes:
determining initial node hop count information and a physical address of a source communication node in the synchronous Ethernet;
controlling the source communication node to generate an extended clock synchronization message template based on a preset data format;
and controlling the source communication node to fill the extended clock synchronous message template according to a first preset frequency quality grade, the physical address and the initial node hop count information to obtain an extended clock synchronous message.
It should be noted that the node hop count information refers to the number of nodes that the extension packet passes through in the data transmission process, for example: the initial node hop count information of the source communication node is 0; the physical address of the source communication node is used for node tracking in the normal data transmission process and generating an extended clock synchronization message of a new node.
It is understood that the preset data format may be a standard ESMC-based message format and a standard data format, and the standard ESMC-based message format and the standard data format may refer to fig. 4 and 5, respectively; compared with the standard ESMC message, the extended clock synchronization message template has one more clockproperty parameter for identifying the clock ID and one more caseded parameter for identifying the clock synchronization hop count.
It can be understood that the first preset frequency quality level refers to an SSM level set during data transmission of the message, and in this embodiment, the first preset frequency quality level is 0x 2.
Step S02: and transmitting the data of the extended clock synchronization message based on the network structure of the communication network.
It should be noted that, after obtaining a complete extended clock synchronization packet, in the process of performing data transmission on the clock synchronization packet based on the network device node structure of the communication network, each time data transmission is performed, 1 is added to the hop count of the extended clock synchronization packet, and a communication node receiving the extended clock synchronization packet generates an extended clock synchronization packet after updating the physical address according to its own physical address and the received extended clock synchronization packet.
In addition, after receiving the extended clock synchronization packet, the new communication node may further extract a frequency quality level in the extended clock synchronization packet, and compare the frequency quality level with a frequency quality level of the new communication node, where the smaller a value corresponding to the frequency quality level is, the higher the priority is, for example: in the network structure shown in fig. 3, when an extended ESMC message is transmitted from a node a to a node b, the SSM levels of the node b themselves are compared, because the local SSM level of each communication node is 0xB, and the SSM level carried by the extended ESMC message is 0x2, the SSM level carried by the extended ESMC message is smaller than the local SSM level of the node b, that is, the priority of the extended ESMC message is higher than the priority of the node b, the node b retains the extended ESMC message, and synchronizes the node a, and feeds back a message with an SSM level of 0xFF to the node a, where the fed-back message is used to confirm message reception, control the node a not to continue sending the same ESMC message and update the local level of the node a.
Further, the step S02 includes:
determining a current communication node according to a physical address in the extended clock synchronization message;
determining a next communication node connected with the current communication node based on a network structure of the synchronous Ethernet;
and sending the extended clock synchronization message to the next communication node.
It can be understood that, since one communication node can perform data communication with multiple communication nodes at the same time, in the process of performing extended ESMC packet transmission, the extended ESMC packet can be forwarded to each connected communication node at the same time, and whether to receive the extended ESMC packet is selected according to the result of comparing the SSM classes, so as to complete data transmission.
Further, after sending the extended clock synchronization packet to the next communication node, the method further includes:
updating node hop count information in the extended clock synchronization message;
when the local frequency quality level of the next communication node is greater than a first preset frequency quality level, determining a next physical address corresponding to the next communication node;
controlling the next communication node to generate a target extended clock synchronization message according to the next physical address, the first preset frequency quality and the updated node hop count information;
and transmitting the target extension clock synchronous message based on the network structure of the synchronous Ethernet.
For example: after the NodeB updates the expanded ESMC message according to the physical address of the NodeB, the communication nodes connected with the NodeB comprise a NodeC and a NodeD, and after receiving the expanded ESMC message sent by the NodeB, the NodeC and the NodeD both feed back a message with the SSM level of 0xFF to the NodeB and then send the updated expanded ESMC message to the NodeE.
In addition, when node e receives the extended ESMC messages sent by node c and node d respectively, since the SSM levels of the two extended ESMC messages are both 0x2, in order to avoid data transmission collision, the priorities of the communication nodes sending the messages can be compared, and the communication node with higher priority is retained, i.e. the extended ESMC message sent by node c is retained, so that node e synchronizes node c.
When comparing the priorities of the communication nodes, the communication node that sends the extended ESMC message may be determined according to the physical address included in the extended ESMC message, and then the communication node is determined according to the predefined priority of the communication node, where in this embodiment, the priority order is node a > NodeB > NodeD > node e > nodf in sequence, and this embodiment does not specifically limit this.
Further, the synchronous ethernet network includes: a source communication node and at least one child communication node;
after the data transmission is performed on the extended clock synchronization packet based on the network structure of the synchronous ethernet, the method further includes:
and when the extended clock synchronization message is not received within the preset time interval of the sub-communication node, deleting the sub-communication node and selecting a clock source again.
It should be noted that the preset time interval may be set to 3S, which is not specifically limited in this embodiment.
In a specific implementation, referring to fig. 10, if a sub-communication node in the 3S communication network does not receive an ESMC packet extended by a source communication node, indicating that there is an error in the source communication node selection of the synchronous ethernet, the source communication node needs to be deleted, and clock source selection is performed again, and a specific logic block diagram of clock source reselection may refer to fig. 11.
The embodiment discloses a method for controlling a source communication node in a communication network to generate an extended clock synchronization message; the extended clock synchronization message is subjected to data transmission based on the network structure of the synchronous ethernet, and in this embodiment, data hop times are calibrated by extending a standard ESMC message, so that the hop times are updated subsequently, and thus, the hop change of the extended clock synchronization message in the data transmission process in the synchronous ethernet is predicted subsequently.
In addition, an embodiment of the present invention further provides a storage medium, where a damage program based on synchronous ethernet is stored on the storage medium, and when executed by a processor, the damage program based on synchronous ethernet implements the steps of the damage method based on synchronous ethernet described above.
Since the storage medium adopts all technical solutions of all the embodiments, at least all the beneficial effects brought by the technical solutions of the embodiments are achieved, and no further description is given here.
Referring to fig. 12, fig. 12 is a block diagram illustrating a first embodiment of a synchronous ethernet-based destruction apparatus according to the present invention.
As shown in fig. 12, a synchronous ethernet-based destruction apparatus according to an embodiment of the present invention includes:
the hop count obtaining module 10 is configured to predict hop count changes of the extended clock synchronization packet in a data transmission process in the communication network when detecting that a source communication node in the communication network is disconnected from a target clock source, so as to obtain a target hop count.
