With reference to Fig. 2, a kind of step of the embodiment of the method for data receiver shown in one exemplary embodiment of the application is shown Rapid flow chart, can specifically include following steps:

Step 101, the target data of network interface card write-in is read from network interface card shared drive.

Illustratively, target data can be for based on udp protocol, Transmission Control Protocol (Transmission Control Protocol, transmission control protocol) etc. agreements data, which may include audio, video data, signaling data etc..

In this step, network interface card shared drive is NIC driver and the memory buffer positioned at network interface card that network interface card is shared Area.Illustratively, network interface card shared drive may include FIFO (First Input First Output, first in first out) buffering Area, buffer circle Ring Buffer (when using to the end of buffer area, start the cycle over use from Buffer again Buffer area) etc..

It should be noted that network interface card shared drive belongs to the memory of network interface card, it is both not belonging to kernel state space, has also been not belonging to User's state space, it belongs to hardware buffer, is network interface card and the buffer area that NIC driver is shared.In trawl performance initialization When, a network interface card shared drive is distributed in the memory of network interface card, this network interface card shared drive is to receive data to network interface card to make , due to being to transmit data to the DMA of network interface card (Direct Memory Access, direct memory access), so net Card shared drive can be the continuous memory of physics.

A kind of scene that possible network interface card receives data is as follows in the present embodiment: data packet packet on cable first by Network interface card obtains, and network interface card can check CRC (Cyclic Redundancy Check, the cyclic redundancy check) verification of packet, guarantees Then the integrality of data is removed packet, frame frame is obtained.Network interface card can also check the target MAC (Media Access Control) address in MAC packet, If with the MAC Address of this network interface card it is different if abandon (except promiscuous mode).Network interface card by frame copy to network interface card it is shared in Deposit, when the data in network interface card shared drive are a complete data packets, network interface card trigger hardware interrupts or software interrupt (if it is Ring Buffer then triggers software interrupt), to notify NIC driver to receive target data.

After NIC driver detects interruption, then target data is read from network interface card shared drive.In a kind of possibility Embodiment in, NIC driver can come out target data copies, and execute step 102.

Step 102, the decapsulation information of the target data is determined.

The NIC driver of the present embodiment can integrate OSI (Open System Interconnect, open system Interconnection) interrelated logic of data link layer, network layer and transport layer in reference model, complete Correlation method for data processing function.

The present embodiment can be applied to the scene of data decapsulation, can first pass through the solution that step 102 obtains target data Packaging information.In one embodiment, decapsulation information can be obtained by obtaining the control information that target data carries.
