Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
A general internal and external network data forwarding flow is shown in fig. 2, and in this process, forwarding of one data packet needs to be performed by two protocol stack processes, two driver processes, and two network card hardware transceiving. Because the hardware of the network card is independent, the network card can be processed in parallel, and the influence on the forwarding delay time is not large; the data processing of the driver is interrupt driven, can be processed in parallel, and has little influence on the forwarding delay time. The network protocol stack of Vxworks is single-task, and two times of protocol stack processing need to be executed in series, so that the forwarding delay time is long.
In order to solve the problem of long delay time, the work flow of network message forwarding is analyzed, the operation time is determined in sections, the root cause of the problem is searched, and after testing, the longest time is occupied when the network protocol stack receives and processes, the forwarding efficiency of the protocol stack is too low, this is the major bottleneck for excessive network forwarding delay, but considering that not all network packets need to be forwarded in actual use, but a part of the data packets are processed in the intelligent network card, and some specific messages need to be forwarded, so in order to reduce the forwarding delay time, the simplest method is to bypass the receiving processing of the network protocol stack, directly submit the data packets to the application program by the driver program, and then forward the data by the application program, while other data packets which do not need to be forwarded still go through the whole flow, so as to solve the delay problem.
Based on the above analysis, with reference to fig. 3, the present invention provides a network message fast forwarding method based on improved network card driver software, which includes the following steps:
step 1, constructing network card driving software supporting a standard TCP/IP protocol stack to support a standard message forwarding and processing function;
step 2, collecting message characteristic information, determining whether a message corresponding to the information needs to be forwarded according to the message characteristic information, and marking the message needing to be forwarded as a characteristic message;
and 3, modifying the network card driving software and forwarding the feature message.
Further, in one embodiment, the message characteristic information in step 2 includes a destination IP address and a source IP address of the message.
Further, in one embodiment, in step 2, it is determined whether the packet corresponding to the information needs to be forwarded according to the packet feature information, and the packet that needs to be forwarded is recorded as a feature packet, which specifically includes:
a user self-defines and constructs a feature message library required to be forwarded, wherein the library comprises a destination IP address and a source IP address corresponding to a message required to be forwarded;
judging whether the collected message characteristic information exists in the characteristic report library, if so, forwarding a message corresponding to the message characteristic information, wherein the message is a characteristic message; otherwise no forwarding is required.
Further, in one embodiment, the collected message feature information is specifically implemented by using a newly added collected message feature information interface function on a dual redundant network card driver or a gigabit network card driver.
Further, in one embodiment, step 3 modifies the network card driver software, and forwards the feature packet, which specifically includes:
modifying a message receiving function in the network card driving software to realize the following steps: the data packet of the feature packet is uploaded to the buffer, a data forwarding requirement notification is sent, and then the data packet is uploaded to the application program by the forwarding data uploading interface function, where the specific logic is shown in fig. 4.
Further, in one embodiment, the forwarding data upload interface function is a newly added interface function on a dual redundant network card driver or a gigabit network card driver.
The invention can meet the forwarding delay of less than or equal to 1ms under the condition of sending mass data, can effectively improve the rapid processing capability of the mass data messages in the industrial computing system, and better meets the high-performance requirements of the industrial computing system in various fields.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
