Embodiment Construction

[0048] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] figure 1 , is a flow chart of a method for forwarding a packet provided by an embodiment of the present invention. Such as figure 1 As shown, the method may include:

[0050] S101. The receiving process in the kernel mode stores the packet received by the network card in the shared memory and notifies the process in the user mode.

[0051] S102. After the user state process maps the physical address of the shared memory to the...

Abstract

The invention discloses a method and device for forwarding a message. The method includes: a kernel-state receiving process stores the message received by a network card in a sharing internal memory and notifies a user-state process; the user-state process maps the physical address of the sharing internal memory to the virtual address of the user-state process and then extracts the message from the sharing internal memory and processes the message; the user-state process stores the processed message in the shearing internal memory and notifies a kernel-state transmitting process; the kernel-state transmitting process transmits the processed message through the corresponding network card. By the method, copying of the message from kernel space to application space is avoided, message forwarding speed is increased, and system resource utilization rate can be increased.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for forwarding messages. Background technique [0002] In the field of network communication technology, it is often necessary to receive packets from the network, and then process the packets accordingly according to system functions. After the processing is completed, for the intermediate device, the message needs to be forwarded from another port. This involves the message forwarding technology among multiple network cards in the same system. In the process of researching the existing message forwarding technology, it is found that the application program implementation method based on socket is adopted. The method is based on the existing operating system platform, and uses socket technology in user space to complete the process of receiving, processing and forwarding network messages. In the whole process, before the network message reaches the application pro...
