Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the method for scheduling ethernet transmission queues includes the following steps:
step 1, analyzing uplink data to obtain a preset transmission priority in the uplink data;
step 2, storing the uplink data into a queue corresponding to the cache according to the transmission priority; the buffer memory is preset with a plurality of queues, and different queues respectively store uplink data with different transmission priorities;
step 3, if the uplink data sending time is up and the buffer is in a data overflow state, sending the uplink data in the non-empty queue according to the transmission priority; and if the uplink data sending time is reached and the cache is in a non-data overflow state, polling the non-empty queue according to the transmission priority, and sending the uplink data in the non-empty queue according to the service quota distributed to the non-empty queue in each turn and the number of bytes allowed to be sent.
According to the method, the uplink data with different transmission priorities are stored in different queues, polling is carried out according to the transmission priorities (namely, each turn of each data has a sending opportunity) in a non-data overflow state, the uplink data are sent according to the service quota and the number of bytes allowed to be sent, the fairness of sending various data is guaranteed, the real-time performance of important data is guaranteed, the transmission mode is adjusted in the data overflow state, the uplink data are sent according to the data overflow state, network congestion caused by uploading of a large amount of data is improved, data loss is avoided, and the reliability of data uploading is improved.
The preset transmission priority mainly sets the transmission priority of the data frame of the sub-device, a priority control layer can be added on a data link layer of a network protocol stack sent by the sub-device, a 32-bit label field is added, and the transmission priority of the data frame is written in the first three bits of the third byte of the label field.
The transmission priority sets 8 levels, which are sequentially reduced from 0 to 7, wherein n is 0 and is the highest transmission priority, the corresponding data is alarm error reporting information, the data with n being 1 is sensor conventional reporting information, the data with n being 2 is video and audio data, and the rest is redundancy design.
The uplink data sent by the sub-device can carry a corresponding transmission priority, and when the data reaches the NR network sending port, the uplink data can be analyzed to obtain the transmission priority of the uplink data, which specifically includes: and adding a data priority analyzing layer above the data link layer by the NR network virtual Ethernet node protocol stack, reading the first three bits of the third byte in the label field, and identifying the transmission priority.
A plurality of queues, generally 8 queues, are set in advance in the buffer, different queues store uplink data of different transmission priorities, and after the transmission priorities are identified, the uplink data are stored in the queues corresponding to the buffer. For example: all uplink data with n equal to 0 are stored in queue Q0All uplink data with n equal to 1 are stored in queue Q1In all uplink data queue Q with n equal to 22In (1).
When the uplink data sending time is up and the buffer is in a data overflow state, the data needs to be uploaded immediately, so a first scheduling algorithm is adopted in the situation, the first scheduling algorithm is used for sending the uplink data in the non-empty queue, namely the queue Q, directly according to the transmission priority0Priority upload, queue Q0Uploading queue Q after uploading1And so on.
And in the uploading process, new uplink data may be stored, and if the transmission priority of the newly stored uplink data in the cache is higher than the transmission priority of the currently transmitted uplink data, the current uplink data transmission is finished, and the newly stored uplink data is transmitted. For example: current upload queue Q1Newly storing the uplink data of n-0, i.e. the queue Q which is empty originally0When the data is available again, the data becomes a non-empty queue, and the uploading queue Q is immediately ended1The uplink data of (2) completes the queue Q first0Uplink data upload of, queue Q0After the uploading is finished, the uploading queue Q is continued1The uplink data of (1).
When the uplink data sending time is up and the cache is in a non-data overflow state, a second scheduling algorithm is adopted under the condition, the second scheduling algorithm is to poll a non-empty queue according to the transmission priority, and the uplink data in the non-empty queue is sent according to the service quota distributed to the non-empty queue in each round and the number of bytes allowed to be sent, and the specific process can be as follows:
11) if the uplink data sending time is up, the cache is in a non-data overflow state, and the queue corresponding to the highest transmission priority is non-empty, the uplink data in the queue corresponding to the highest transmission priority is sent out first, then the polling of the remaining non-empty queues is carried out according to the transmission priority, and the uplink data in the remaining non-empty queues are sent according to the service quota distributed to the remaining non-empty queues in each turn and the number of bytes allowed to be sent;
12) and if the uplink data sending time is up, the cache is in a non-data overflow state, and the queue corresponding to the highest transmission priority is empty, performing non-empty queue polling according to the transmission priority, and sending the uplink data in the non-empty queue according to the service quota distributed to the non-empty queue in each round and the number of bytes allowed to be sent.
In 11) and 12) above, performing non-empty queue polling according to the transmission priority, and sending the uplink data in the non-empty queue according to the service quota allocated to the non-empty queue in each round and the number of bytes allowed to be sent, where a specific process may be:
1) sending the uplink data in the non-empty queues according to the transmission priority (the transmission priority is high for priority transmission) according to the initial service quota distributed to each non-empty queue and the number of bytes allowed to be sent;
the network service can be abstracted into a set of system network resources, the service quota can be understood as the allocation amount of the network resources, and is also allocated according to the transmission priority (the allocation with high transmission priority is more), the number of bytes allowed to be sent is one element in the set of the service quota, and the data is sent according to the service quota and the number of bytes allowed to be sent;
2) if the non-empty queue exists, calculating the remaining uplink data in the non-empty queue; if the non-empty queue does not exist, the uplink data transmission is finished;
3) calculating the weight of each non-empty queue in the round according to the remaining uplink data and the initial service quota in the non-empty queue;
the calculation formula is as follows:
Figure BDA0003524749550000091
wherein R iskIs the weight of the non-empty queue corresponding to the k-th transmission priority N, N is the defined number of queues, usually 0 ≦ N ≦ 8, N ≦ N,

4) calculating the service quota of each non-empty queue in the round according to the weight and the initial service quota;
the calculation formula is as follows:
QDn(k)＝QDn(1+Rk)
wherein QDn(k) Transmitting the service quota of the non-empty queue corresponding to the priority n for the kth round;
5) and sending the uplink data in the non-empty queues according to the transmission priority according to the service quotas distributed to each non-empty queue in the round and the number of bytes allowed to be sent, and turning to 2).
At the beginning, if TAB { Q }n1(n ≠ 0), i.e., there is Q present0Other non-empty queues, DCn＝QDn(n ≠ 0), otherwise DCnWhen the SAT is equal to 0, n (n is equal to 0), polling all the non-empty queues according to the priority, and sequentially transmitting data according to the service quota and the number of bytes allowed to be transmitted; wherein TAB records all queue states, DCnIs a queue QnSAT indicates the amount of transmission priority state of the current transmission queue in the margin (remaining uplink data) after transmission of data.
In the first round, queue Qn(n ≠ 0) number of bytes allowed to be transmitted

wherein the content of the first and second substances,

in a similar manner, queue QnAfter the kth round sends data, the weight of the next round is:
Figure BDA0003524749550000105

In the uploading process, if new data is added into the cache, the transmission priority of newly stored uplink data is not higher than the transmission priority of currently transmitted uplink data, the transmission mode is not adjusted, and data are transmitted according to polling and the initially allocated service quota; if the transmission priority of the newly stored uplink data in the cache is higher than the transmission priority of the currently sent uplink data, the currently sent queue still sends the uplink data according to the current service quota, the transmission priority is smaller than the queue of the currently sent queue to redistribute the service quota, and the service quota is specifically distributed as the minimum service quota; the data with n equal to 0 is the alarm error reporting information, and the data needs to be uploaded preferentially under any condition, so that the queue Q corresponding to the highest transmission priority level0Storing new uplink data and ending current uplink dataAnd sending the newly stored uplink data according to the sending.
The method transmits the data in a polling way under the conventional condition, and each turn of each data type has the opportunity of transmitting the data, so that the fairness of transmitting each type of data is ensured; network service quotas are distributed according to the priorities, the network service quotas are sequentially sent according to the priority order, different strategies are determined according to the priority condition of the data being stored, and the instantaneity of important data is guaranteed; monitoring the data allowance of the queue, adjusting the network service quota in the next round according to the data allowance, and adjusting the queue scheduling algorithm in time when the data overflows, thereby improving the network congestion caused by uploading a large amount of data, avoiding the data loss and improving the data uploading reliability.
