Problems solved by technology

[0005] In addition, as the types of board services continue to increase, the amount of data doubles. Since there was no unified subcontracting mechanism between the network management and transmission equipment in the past, each time a new board is added, a subcontracting process is required, which greatly increases In order to reduce the cost of work, the communication efficiency between the network management system and the transmission equipment needs to be improved urgently

Embodiment

[0051] Figure 2 is a complete flow of sending and receiving data.

[0052] 1. When there is a large amount of data to be sent, the sending task regularly obtains messages from the sending queue and puts the data into the sending buffer. When the data in the downstream RAM has been successfully read and the sending buffer is not empty, the sending task will take out multiple message data from the buffer, if it is a large packet of message data, start the sub-packet mechanism, and then write the message data into the downstream RAM . The buffering mechanism is used to realize flow control, and the simple retransmission function is started in case of packet loss or transmission failure, and the polling method is adopted. As shown in Figure 4.

[0053] 2. When the transmission device uploads a large amount of data, it takes an interrupt method from the upstream dual-port RAM to the receiving buffer. If it is sub-packetized data, perform grouping processing.

Abstract

The invention provides a method for transmitting data from network management system to a transmission equipment, which comprises the following steps: (a) acquiring message from a transmitting queue by a transmission task and storing the message data in a transmission buffer region; and (b) extracting the message data from the buffer region by the transmission task when a data needs to be written to a lower random access memory RAM and the transmission buffer is not empty, and writing into the lower RAM. The invention also provides a method for receiving data from the transmission equipment by the network management system, which comprises uploading the data to an upper RAM by the transmission equipment, generating an interrupt signal, and reading data from the upper RAM when a receiving task receives the interrupt signal.

Description

technical field [0001] The invention relates to a method for sending and receiving data with a large amount of data between a main control single board of a network management system and a business single board of a transmission device. Background technique [0002] In the hierarchical structure of the existing network management, the inter-board communication port is an interface between the network management system and the transmission equipment, as shown in FIG. 1 . [0003] The reliable and efficient transmission mechanism of a large amount of data between boards is composed of some modules, including sending tasks, receiving tasks, packet tasks, timing tasks and other tasks, as well as sending queues, and also includes two buffers such as sending buffer and receiving buffer Area. [0004] In the existing communication mechanism, complex communication protocols cannot be used due to efficiency reasons, but the reliability of communication must be fully guaranteed. The...
