Network datagram processing method, system and device

Abstract

The invention is applicable to the data communication field and provides a network data message processing method, a system and a device; the processing method includes that a ring buffer queue is constructed; the queue is configured with three pointers, including a generator pointer, an intermediate pointer and a sender pointer; the data message received by a network processor and unprocessed by a coprocessor is stored in the ring buffer queue through the generator pointer; the coprocessor acquires the data message from the ring buffer queue through the intermediate pointer for processing the data message; the processed data message is stored in the ring buffer queue through the intermediate pointer; the network processor acquires the data message processed by the coprocessor from the ring buffer queue and sends the processed data message through the sender pointer. Compared with the prior art, the network data message processing method can greatly reduce the cost brought by the data transmission and synchronism sustaining and improve the processing rate of the data message and the utilization rate of the coprocessor greatly.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a network data message processing method, system and equipment. Background technique [0002] Currently, network security devices on the market usually use a general-purpose industrial control platform combined with a hardware coprocessor architecture. In this architecture, the processing method for network data packets is usually to maintain separate The data queue, and use the producer and consumer model to realize the processing of data packets. The processing model is as follows figure 1 Shown: [0003] In the network processor, the network card receiving queue and the network card sending queue are respectively used to manage the data packets received by the network card that have not been processed by the coprocessor and the data packets that can be sent by the network card immediately after being processed by the coprocessor. Among them, coprocessor queues a...
