- the mission requirement can be determined to be a carrier or a maximum transmission rate of 50 Mbps, or a combination of the two.
- the present invention does not limit the type of task requirements.
- the task processing path refers to a combination of processing units in a resource pool for completing transmission of a data stream.

- the choice of RRU and PPU can be analyzed in a similar way. .
- the task processing path may also be dynamically changed according to the monitoring data of the network or the actual state of the processing unit in the resource pool. For example, if the load of the LTE carrier is increased and the processing capability of the PPU1 cannot be satisfied, an appropriate processing unit (such as PPU2) may be selected from the protocol resource pool to be added to the task processing path. Similarly, if the load of the LTE carrier is reduced, some processing units can be reclaimed for use in other virtual base stations. In this way, the utilization rate of the processing unit can be effectively improved.

- a notification message is sent to the processing unit to perform the action of notifying the destination address. For example, if the data stream of the RRU 2 needs to be forwarded to the BBU 1 , the address of the BBU 1 is the destination address of the data stream on the RRU 2 , and the data stream is completed. To transmit, you need to notify RRU2 of the address corresponding to BBU1.

- Step S340 determining whether feedback of all processing units is obtained.
- a feedback message for the destination address notification behavior may be further received from all processing units before the task processing is initiated. If the destination address configuration is successful, step S350 is performed; otherwise, it may choose to continue waiting for a period of time, retransmit, or consider updating the task processing path. In this way, it is ensured that the data streams are resynchronized after each processing unit is successfully configured, thereby avoiding transmission data errors caused by processing unit abnormalities.
- the feedback information received from the processing unit includes, but is not limited to, the following:
- the information number is the number of the notification destination address information to indicate which of the notification destination addresses corresponds to the feedback information.
- the feedback message may further include whether the processing unit is working normally, resource utilization, and ground. Changes in the address, etc.
- the items listed above may be included in one message or in multiple messages.
- a processing unit exception is indicated separately using a status report message.

For example, when the destination address is configured successfully, the destination address is configured incorrectly, the processing unit is abnormal, or the load of the processing unit exceeds the threshold, and the processing unit's own address is changed, the report is immediately reported, so that whether to update the task processing path may be determined based on the feedback message. .

- the information interaction between the control layer and the processing unit includes sending a notification message to the processing unit notifying its destination address and receiving feedback information from the processing unit.
- the control layer can also be responsible for the allocation of destination addresses of some processing units in the resource pool. For example, for an Ethernet switch, the MAC address of the connected device is self-contained and does not require additional allocation. For an SRIO switch, for example, the address of the connected device needs to be assigned. After the control layer allocates addresses to some processing units, it notifies the corresponding switch and processing unit to enable the switch to complete the correspondence between the processing unit address and the port. As long as the two parties performing information interaction can uniquely identify the target processing unit according to the destination address, the assigned destination address can be in various forms, for example, for the DSP address, it can be identified by a simple unified number, or by using a DSP. The rack number + board number + local DSP label is uniquely determined.
- the control interface between the control layer and the processing unit is a logical interface, which may also exist between the control layer and the switching network.
- the information interaction between the control layer and the processing unit may be directly communicated with each processing unit by the control layer, or the control layer may first notify the management agent, and the management agent further informs the processing unit.
