101. the data forwarding device receives data sent by at least one client through the data access module, and sends the data received through the data access module to the data cache module for storage.
102. And when the data storage state in the data cache module meets the data sending condition, the data forwarding device sends the data sending instruction to the data sending module through the data cache module.
103. And the data forwarding device sends the data stored by the data caching module through the data sending module according to the data sending instruction.
Further, whether the data access module sends and stores the received data in the data cache module or the data cache module sends the data to the data sending module, the transmission of the data is performed according to a First-in First-out (FIFO) principle.
According to the data transmission method provided by the embodiment of the invention, when the data storage state of the data stored in the data cache module meets the data sending condition, the data sending module sends the data stored in the data cache module according to the data sending instruction sent by the data cache module, so that the awakening times of the data sending module are reduced, the idle dormancy time is increased, and the power consumption of the data forwarding device is further reduced.
The invention discloses a data transmission method, as shown in fig. 2, the data transmission method in this embodiment determines whether to send a data sending instruction according to the amount of data stored in the whole data cache module and the timing time, and the data transmission method includes the following steps:
201. the data forwarding device receives data sent by at least one client through the data access module, and sends the data received through the data access module to the data cache module for storage.
201a, the data forwarding device stores the data received by the data access module and sent by at least one client into a pre-storage area in the data cache module.
The pre-storage area in the data cache module is a reserved part of the data cache module and is not included in the calculation of the storage space in the data cache module.
201b, the data forwarding device sequentially judges whether each client of the at least one client has a corresponding serial number identifier in the data cache module according to the sequence of data storage.
If the number identifier exists in the data cache module, the process goes to step 201c1, and if the number identifier does not exist in the data cache module, the process goes to step 201c 2.
201c1, the data forwarding device stores the data sent by the client with the number identification in the data cache module into the storage area of the client with the number identification corresponding to the data cache module.
Or,
step 201c2 includes the following steps:
a1, the data forwarding device generates a new number identification for the client without number identification.
a2, the data transfer device judges whether the data buffer module has a free storage area.
If the determination result is that there is a free storage area, the process goes to step a3, and if the determination result is that there is no free storage area, the process goes to step 201c 3.
a3, the data transfer device applies for a storage area marked by the new number mark in the free storage area, and stores the data sent by the client corresponding to the new number mark in the storage area.
Step 201c3 includes the following steps:
b1, the data transfer device judges whether the data cache module has a storage area which does not store data.
b2, if there is a storage area not storing data in the data cache module, the data forwarding device selects the storage area with the longest idle time in all the storage areas not storing data to release preferentially, and configures the storage area with the longest idle time to the client corresponding to the new number identifier so as to store the data sent by the client corresponding to the new number identifier.
202. And if the data cache module does not have a storage area which does not store the data, the data forwarding device sends the data sending instruction to the data sending module through the data cache module.
203. And the data forwarding device sends the data stored by the data caching module through the data sending module according to the data sending instruction.
Further, whether the data access module sends and stores the received data in the data exchange module or the data cache module sends the data to the data sending module, the data transmission is carried out according to the first-in first-out (FIFO) principle.
In addition, when the data transmitted by the data transmission method includes uplink data and/or downlink data, the data cache module between the data access module and the data sending module in the data forwarding device may be divided into an uplink data cache module and/or a downlink data cache module.
When the uplink data is initiated, the data access module receives the uplink data sent by at least one client and stores the received uplink data in the uplink data cache module. When the uplink data cache module is full of uplink data and has no storage area which does not store the data, the uplink data cache module sends a data sending instruction to the data sending module, and finally the data sending module sends the uplink data in the data cache module to the remote client according to the data sending instruction.
When downlink data is initiated, the data sending module receives the downlink data sent by at least one remote client, and stores the received downlink data in the downlink data caching module. And when the downlink data cache module is full of downlink data and has no storage area which does not store the data, the downlink data cache module sends a data sending instruction to the data sending module, and finally the data sending module sends the downlink data in the data storage module to the client according to the data sending instruction.
Further, when there are uplink data and downlink data simultaneously, the sizes of the storage spaces of the uplink data cache module and the downlink data cache module may be allocated according to the actual service demand, and generally do not have symmetry, because the uplink data is generally request information for the actual service, and the downlink data is generally corresponding download information of the request information for the actual service in the uplink data, the space of the downlink data cache module may be larger than that of the uplink data cache module, so as to meet the actual requirement for asymmetric data throughput.
According to the data transmission method provided by the embodiment of the invention, when the data storage state of the data stored in the data cache module meets the data sending condition, the data sending module sends the data stored in the data cache module according to the data sending instruction sent by the data cache module, so that the awakening times of the data sending module are reduced, the idle dormancy time is increased, and the power consumption of the data forwarding device is further reduced.
The invention discloses a data transmission method, as shown in fig. 3 and 4, the data transmission method mentioned in this embodiment is to determine whether to send a data sending instruction according to the amount of data stored in a data cache module within a preset timeout period, as shown in fig. 3, when the data storage method is described from a microscopic perspective (i.e. the amount of data stored in each client in the data cache module), the method includes the following steps:
301a, the data forwarding device determines whether there is data in the data cache module, which is sent by at least one client through the data access module.
302a, if the data cache module does not store data, the data forwarding device starts a timer set in the data cache module.
303a, the data forwarding device receives data sent by at least one client through the data access module, and sends the data to the data cache module for storage through the data access module.
304a, the data forwarding device determines whether the storage area corresponding to each client of the at least one client is full of data within a timeout period.
Step 305a may have several cases as follows:
305a1, when the storage area of any client is full of data, the data transfer device sends a data transmission instruction to the data transmission module via the data cache module.
Or,
305a2, if all the storage areas of the clients are not full of data, the data forwarding device calculates the average value of the maximum data filling rate of the data cache module in all the timeout periods after the timer of the data cache module is started.
The specific calculation process of step 305a2 is as follows:
a1, the data forwarding device records the data filling rate of the storage area of each client in at least one client in each timeout period after the timer of the data caching module is started.
a2, the data forwarding device selects the maximum value of the data filling rate of the storage area of each client in at least one client in each timeout period after the timer of the data caching module is started as the maximum data filling rate of the data caching module in each timeout period.
a3, the data forwarding device calculates the average value of the maximum data filling rate of the data caching module in each timeout period after the timer of the data caching module is started.
305a3, when the timer of the data caching module does not reach the timeout period and the average value of the maximum data filling rate is greater than the preset upper limit threshold, the data forwarding device sends the data sending instruction to the data sending module through the data caching module.
Or,
305a4, when the timer of the data caching module reaches the timeout period and the average value of the maximum data filling rate is smaller than the preset lower threshold, the data forwarding device sends the data sending instruction to the data sending module through the data caching module.
Specifically, the data forwarding device records the data filling rate of the storage area of each client in at least one client in the timeout period in each timeout period after the timer of the data caching module is started, then selects the maximum value as the maximum data filling rate of the data caching module in each timeout period, stores the maximum data filling rate in a virtual circulation container with a storage function, stores the maximum data filling rate once every time the circulation container with the timeout period passes, and calculates the average value of all the maximum data filling rates stored in the virtual circulation container once. And stopping the calculation process of the average value of the maximum data filling rate until the average value of the maximum data filling rate is greater than a preset upper limit threshold and the timer of the data cache module does not reach the timeout period, or the average value of the maximum data filling rate is less than a preset lower limit threshold and the timer of the data cache module reaches the timeout period. In addition, in the first timeout period after the timer of the data caching module is started, since only one maximum data filling rate is stored in the circulation container, the average value at this time is an average threshold preset in the circulation container.
Specifically, when the average value of the maximum data filling rate is greater than a preset upper threshold, it indicates that the data transmitted in the data transmission process is continuous, and all data are directly transmitted; when the average value of the maximum data filling rate is smaller than the preset lower limit threshold, it indicates that the data transmitted in the data transmission process is intermittent, and all data can be transmitted only when the timer of the data cache module reaches the timeout period.
306a, the data forwarding device sends the data stored in the data caching module through the data sending module according to the data sending instruction.
As shown in fig. 4, the data storage method is described in a macro-angle (that is, it is determined that the time for the data cache module to store data reaches a preset timeout period), and the method includes the following steps:
301b, the data forwarding device determines whether the data cache module stores data sent by at least one client through the data access module.
302b, if the data cache module does not store the data, the data forwarding device starts a timer set in the data cache module.
303b, when the timing time set by the timer in the data caching module exceeds a preset timeout period, the data forwarding device sends the data sending instruction to the data sending module through the data caching module.
304a, the data forwarding device sends the data stored in the data caching module through the data sending module according to the data sending instruction.
Optionally, when the data caching module does not store data within a preset timeout period, the timer set in the data caching module is stopped.
Further, whether the data access module sends and stores the received data in the data exchange module or the data cache module sends the data to the data sending module, the data transmission is carried out according to the first-in first-out (FIFO) principle. And in order to avoid the possibility of failure of the client applying for the space of the data cache module, the size of the space of the data cache module is selected according to the actual requirement.
When the data transmitted by the data transmission method includes uplink data and/or downlink data, the data cache module between the data access module and the data sending module in the data forwarding device may be divided into an uplink data cache module and/or a downlink data cache module.
When the uplink data is initiated, the data access module receives the uplink data sent by at least one client, and before the received uplink data is stored in the uplink data cache module, the uplink data cache module starts the timer at first and then stores the uplink data. When the time for caching the uplink data by the uplink data caching module reaches a preset timeout period, the data stored in the storage area of the client reaches a preset quantitative value or when the time for caching the uplink data by the uplink data caching module reaches the preset timeout period, the uplink data caching module sends a data sending instruction to the data sending module, and finally the data sending module sends the uplink data in the data caching module to the remote client according to the data sending instruction.
