Problems solved by technology

[0009] In the prior art, when an Ethernet switch realizes sending and receiving data messages, the number of interrupted messages per unit is a fixed value, which cannot be adjusted according to the transmission status of data messages in the process of sending and receiving data messages after being preset.
The fixed PPI value is not suitable for the two cases of high and low data packet transmission rates, and the transmission and processing effect of data packets is poor
Taking receiving data packets as an example, when the PPI value is large, if the receiving rate of data packets is low, the processing delay of data packets will be large; on the contrary, when the PPI value is small, if the receiving rate of data packets is high, The higher the interrupt frequency, the more CPU resources will be consumed

Embodiment Construction

[0033] In the embodiment of the present invention, the transmission frequency of the data message is detected, and according to the detection result, it is compared whether the transmission frequency of the data message is less than the preset transmission frequency value, and the unit interrupt message value of the data message is determined according to the transmission frequency of the data message Carry out dynamic adjustment, when the transmission frequency of the data message is less than the preset transmission frequency value, the unit interrupt message value of the data message is set to the preset unit interrupt message value; when the transmission frequency of the data message is greater than or equal to the preset When setting the transmission frequency value, calculate the ratio of the transmission frequency of the data message to the preset transmission frequency value, and further obtain the current unit interrupt message value of the data message according to the...

Abstract

The invention discloses a data message process method and a data message process device, wherein the data message process method includes: detecting the transmission frequency of the data message; comparing the transmission frequency whether is smaller than the given one; when the transmission frequency of the data message is smaller than the given one, the ration of transmission frequency of the data message and the given one is computed, further obtaining the current unit interrupt message value according to the ratio; the data message is processed with interrupt handling according to the given current unit interrupt message value or the current unit interrupt message value. The invention can effectively increase the transmitting and processing effect of the data message and ensure the delay and the CPU processing efficiency.

Description

technical field [0001] The invention relates to data exchange technology, in particular to a data message processing method and a data message processing device. Background technique [0002] With the continuous development of computer network technology, local area network has brought more convenience to people's work and life due to the advantages of resource concentration and resource sharing. In the commonly used LAN, the LAN switching technology can provide effective network segment division for the shared LAN, so that each user in the LAN can share the maximum bandwidth as much as possible. In the LAN switching technology, the switch is the main connecting device and has been widely used at present. At present, a switch mainly forwards data streams through a switch chip, wherein the switch chip generally adopts an application specific integrated circuit (Application Specific Integrated Circuit, hereinafter referred to as ASIC), and forwards data packets through a hard...
