Detailed Description
The following examples are provided to further illustrate the present invention.
The data interaction method for the test device of the ring main unit comprises the following steps:
the processing device executes data interaction with a background device in the WLAN via the WIFI module;
as such, the structure of the processing device of the present invention for performing data interaction with a background device in the WLAN via the WIFI module includes: the first switch is synchronously connected with a plurality of adjacent switches including a second switch, a third switch and a fourth switch, and the second switch is synchronously connected with a plurality of adjacent switches including a first switch, a fourth switch, a fifth switch and a sixth switch; when the first switch transfers the data transferred by the processing equipment, the data to be transferred is synchronously transferred to the second switch, the third switch and the fourth switch, the second switch, the third switch and the fourth switch are additionally arranged in the database of the switch which has received the data, after the second switch receives the data, the data are also transferred to the first switch, the fourth switch, the fifth switch and the sixth switch which are connected with the second switch, and the first switch, the fourth switch, the fifth switch and the sixth switch are switches which initially receive the data and are registered in the database of the switch which initially receives the data; in this case, for the entire WLAN, since the first switch and the fourth switch re-transmit data to the first switch and the fourth switch again in the database of the switch that has received the data, the load of WLAN transmission is additionally increased even if the data cannot be re-acquired by the first switch and the fourth switch.
Therefore, the second switch, the third switch and the fourth switch in the database of the switch which has received the data are compared with the fourth switch, the fifth switch and the sixth switch in the database of the switch which initially receives the data to obtain the database of the switch which does not receive the data, the switches in the database of the switch which does not receive the data are the fifth switch and the sixth switch, and the data only need to be transmitted to the fifth switch and the sixth switch in the list of the switches which do not receive the data, so that the load of WLAN transmission is greatly reduced, and the data transmission performance is improved.
The method for the processing device to perform data interaction with the background device in the WLAN via the WIFI module includes:
step 1, obtaining data to be transmitted, wherein the data to be transmitted has a database of a switch which receives the data, and the data of the database of the switch which receives the data is formed by the switch which receives the data to be transmitted;
step 2, a database of an exchanger which initially receives data is obtained, and the data of the database of the exchanger which initially receives the data is formed by the exchanger which needs to receive the data to be transmitted;
the switches connected to each other, all adjacent to the switch that passed the data, are the switches that initially received the data.
And step 3: identifying a category of the data to be communicated, the category being one within a data frame or raw data;
in the data interaction between the processing equipment and background equipment in the WLAN through the WIFI module, the interactive data comprises original data and data frames; the processing device can perform original data forwarding on an adjacent switch in an original state in an end-to-end mode after obtaining original data, the adjacent switch can perform the forwarding process again after obtaining the original data, redundant original data can be forwarded again among a plurality of switches, the switch used for framing can frame a data frame constructed after framing the original data, the switch used for framing or the original data can perform framing on the original data, data frame forwarding can be performed on the adjacent switch after constructing the data frame, and the adjacent switch can perform the forwarding process again after receiving the data frame.
And 4, step 4: if the type of the data to be transmitted is original data, constructing a database of the switch which does not receive the data by virtue of the database of the switch which receives the data and the database of the switch which initially receives the data;
further, it is sequentially determined whether the switch in the database of the switch which initially received the data is in the database of the switch which received the data, and the database of the switch which did not receive the data is created by the switch which did not exist in the database of the switch which received the data.
And 5: passing the raw data to a receiving data switch within the database of the receiving data switch.
If X switches are arranged in the WLAN, each switch is connected with Y adjacent switches at the highest level, the duration of data transmission is not related, and only the number of data transmission returns is related; such a switch is connected to a neighbouring switch and only two special conditions are present for all neighbouring switches to which the neighbouring switch is also connected: each switch in the WLAN is connected to the same adjacent switch, i.e., all switches are redundant, or all switches in the WLAN are connected to different switches.
According to the method for the processing equipment to perform data interaction with the background equipment in the WLAN through the WIFI module, the data interaction is only required to be forwarded once under the condition that X is equal to 1;
only have to forward Y times on condition that X is not equal to 1 and X is equal to the value of Y minus one;
assuming that each core switch is connected to Y adjacent switches, then there are (X/(Y + 1)) core switches, given that X is not equal to 1 and X is equal to the value of Y minus one, since the Y adjacent switches to which each core switch is connected are identical, i.e. a core switch has at most only to forward one round, i.e. (X/(Y + 1)) round; if Y adjacent switches connected are different, then at most (X/(Y + 1)). times.Yback; namely, a transaction of the new scheme needs to be sent to the whole network in a group mode, and if the time length is not related, only the return number is related, the range of the return number which needs to be transmitted is between (X/(Y + 1)) and (X/(Y + 1)) × Y.
If the existing method for transmitting data to all connected switches is used, the same method is used, under the condition that X switches are arranged in a WLAN, and each switch is connected with Y adjacent switches at the highest, the (X/(Y + 1)) × Y loop is transmitted constantly; under certain conditions, it is difficult to have completely different conditions occurring in a WLAN when switches connected to a switch are connected, but rather adjacent switches are often more or less redundant with each other; therefore, the processing device provided by the invention can reduce WLAN transfer burden and improve WLAN transfer performance by performing data interaction with the background device in the WLAN through the WIFI module.
In addition, the data transmission method of the invention cannot have adverse effect on the WLAN in reliability; if the switch controlled by the hacker is provided, the forwarding of the data is not intentionally carried out, and the switch controlled by the hacker can also carry out the same malicious mode even if the data transmission method is not used; therefore, the data transmission method provided by the invention has no change on the reliability of data transmission.
The method for the processing device to perform data interaction with the background device in the WLAN via the WIFI module includes:
step 6, adding the switches in the switch list which does not receive the data into the database of the switch which receives the data, and obtaining the refreshed database of the switch which receives the data;
further, after the switch which does not receive the data receives the data, the switch which does not receive the data is synchronously added into the database of the switch which receives the data, so as to achieve the refreshing of the database of the switch which receives the data.
And 7, transmitting the refreshed database of the switch which has received the data to the switch which receives the data.
Furthermore, the refreshed database of the switch which has received the data is transmitted to the switch which has received the data, and when the switch which has received the data transmits the data to another switch which has initially received the data, the switch which has initially received the data is determined whether the another switch which has initially received the data is present in the database of the switch which has received the data after the refreshing, thereby preventing the data from being transmitted again and reducing the load of WLAN transmission.
The constructing the database of the switch which does not receive the data by means of the database of the switch which has received the data and the database of the switch which initially receives the data comprises the following steps:
sequentially determining whether the switch in the database of the switch initially receiving the data is in the database of the switch receiving the data;
creating a database of switches that have not received data with a switch mechanism that is not in the database of switches that have received data.
If the type of the data to be transmitted is a data frame, the method for transmitting the data frame comprises the following steps:
as if the switch acquires a data frame, the switch transmits the attribute parameters of the data frame, the attribute parameters comprise data records, the switch receives the attribute parameters of the data frame, if the switch of the received data stores the data in the data records of the data frame, the switch sequentially determines whether the data in the data records of the data frame are stored in the switch of the received data, if so, the switch directly uses the data stored in the switch of the received data to transmit the data to the data frame, if not, the switch constructs the data records not stored by the data of the switch not stored in the received data, constructs the data adding instructions by the data records not stored, constructs the added data by the data adding instructions, and transmits the added data to the switch of the received data.
Step A-1, if the kind of the data to be transmitted is a data frame; passing an attribute parameter of the data frame to a data-accepting switch within a database of the switch that initially received the data, the attribute parameter having a data record;
in a data frame, a switch receives new original data in a normal state, and the switch transmits the original data to all adjacent switches in real time; the whole original data of a switch is sent to the adjacent switch in a group, and then the switch constructs a data frame, under the condition, the switch only needs to transmit the attribute parameters of the data frame to the adjacent switch, and does not need to transmit the whole data frame again, so that the data transmission capacity of the whole data frame can be effectively reduced, and the WLAN transmission performance is improved; during the transmission and forwarding of data frames among the switches, the existing data frame transmission mode is to transmit a complete data frame, and the data frame at this time has original data, so that the capacity requirement of the data frame is not small, the frequency band of the WLAN can be partially consumed, and the performance that the weight of the original data in the WLAN is greater than that of the data frame is combined, so that the subsequently transmitted data frame only has an integral serialized attribute parameter record is improved, and after receiving the attribute parameters of the data frame, the switch receiving the data can actively write the existing original data into the data frame on the switch receiving the data, so as to reduce the retransmitted data in the WLAN and achieve the purpose of reducing the load of the frequency band; in addition, because the original data of the switch receiving the data is subjected to rationality check during registration, the proofreading can be omitted during writing, and the operation performance is improved; the original data that is still lost is obtained by means of a data add instruction towards the switch that transferred the data, which then constructs the add data by means of the data add instruction, and then passes the small increase back to the switch that received the data.
Step A-2, the exchanger which receives the data is determined whether to store the data in the data record;
and step A-3, if the data in the data record is not stored in the data receiving switch, the data receiving switch receives the data frame.
Furthermore, under specific conditions, the condition that original data is not transmitted and only data frames are transmitted is difficult to occur between each switch and the adjacent switch; the overall improvement in WLAN delivery performance is significant.
For example, through the practice of performing transfer and forwarding of original data and data frames by using five switches, experimental data for performing data transfer on all adjacent switches is set, the capacity of the transferred data is 168000bits, while the capacity of the processing device for performing data transfer by using the WIFI module and performing data interaction with background devices in the WLAN is 35200bits, compared with the existing method for performing data transfer on all adjacent switches, the transferred data traffic is reduced by 500%, and the adverse effect of high-capacity re-transferred data on the WLAN transfer performance can be overcome.
The method for the processing device to perform data interaction with the background device in the WLAN via the WIFI module further includes:
the switch receiving the data determines whether the attribute parameter is reasonable;
and if the attribute parameters are reasonable, the switch receiving the data receives the data frame.
The determining whether the attribute parameter is reasonable comprises the following steps:
the attribute parameter has a hash function one;
step A-4, constructing a hash function II through a preset coding algorithm by means of the attribute parameters;
step A-5, the first hash function and the second hash function are determined to be different;
step A-6, if the hash function one and the hash function two are the same, then the attribute parameter is reasonable.
Further, if the switch receiving the data stores the data in the data record of the data frame, the method further includes:
b-1, sequentially determining whether the data in the data record of the data frame is stored in the switch for receiving the data;
step B-2, constructing a data record which is not stored by means of the data of the switch which is not stored in the received data, and constructing a data adding instruction by means of the data record which is not stored;
step B-3, building the adding data by means of the data adding instruction;
and B-4, transmitting the added data to the switch for receiving the data.
If the switch receiving the data stores the data in the data record of the data frame, the method further comprises the following steps:
the addend data has a hash function of three;
b-5, constructing a hash function IV by means of a preset coding algorithm according to the added data;
step B-6, determining whether the hash function three boxes and the hash function four are the same;
step B-7, if the hash function three is the same as the hash function four, the added data is reasonable;
and B-8, if the added data is reasonable, the exchanger receiving the data receives the added data.
All switches in the invention are WIFI switches in the WLAN.
Thus, the present invention provides a method for a processing device to perform data interaction with a background device in a WLAN via a WIFI module, including: acquiring data to be transferred, wherein the data to be transferred is provided with a database of a switch which receives the data, and the data of the database of the switch which receives the data to be transferred is formed by the switch which receives the data to be transferred; acquiring a database of a switch which initially receives data, wherein the data of the database of the switch which initially receives the data is formed by the switch which is to receive the data to be transmitted; recognizing the type of the data to be transmitted, and if the type of the data to be transmitted is original data, constructing a database of the switch which does not receive the data by virtue of the database of the switch which receives the data and the database of the switch which initially receives the data; passing the raw data to a switch that receives data in a database of the switch that does not receive data; if the kind of the data to be transferred is a data frame; the attribute parameter of the data frame is transmitted to the switch of the received data in the database of the switch of the initially received data, the attribute parameter has a data record, the switch of the received data is determined whether the switch of the received data stores the data in the data record, if the switch of the received data does not store the data in the data record, the switch of the received data receives the data frame, if the switch of the received data stores the data in the data record of the data frame, the data stored in the switch of the received data is directly used to be written into the data frame, the data in the data record of the data frame is also sequentially determined whether the switch of the received data stores the data, the data record not stored is constructed by the data of the switch not storing the received data, and a data adding instruction is constructed by the data record not stored, and constructing extension data by means of the data extension instruction, and transmitting the extension data to the switch for receiving the data.
