[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a first embodiment of the present invention provides a gigabit ethernet packet loss detection method. Specifically, the method for detecting the packet loss of the gigabit ethernet network provided by the embodiment of the present invention includes, for example, the steps of:
s11: initializing a kilomega Ethernet card connected with a network cable;
s12: acquiring an IP address of a target gateway connected with the gigabit Ethernet card;
s13: sending a detection data packet to the target gateway pointed by the IP address so that the target gateway can generate a feedback data packet according to the detection data packet; the detection packet may be, for example, a network Control message protocol (ICMP) packet. The number of detection packets may be, for example, 100, or other number.
S14: receiving the feedback data packet from the target gateway; wherein the feedback packet may also be an ICMP packet, for example.
S15: and judging whether the gigabit Ethernet card has packet loss or not according to the detection data packet and the feedback data packet.
In another embodiment of the present invention, step S15 specifically includes:
calculating a packet loss rate according to the number of the detection data packets and the feedback data packets, wherein the packet loss rate is a ratio of the number difference of the detection data packets and the feedback data packets to the number of the detection data packets; and when the packet loss rate is not greater than a preset packet loss rate threshold value, judging that the gigabit Ethernet card has no packet loss, otherwise, judging that the gigabit Ethernet card has the packet loss.
In another embodiment of the present invention, the method for detecting gigabit ethernet packet loss further includes:
and when the gigabit Ethernet card has packet loss, adjusting the transmission mode of the gigabit Ethernet card to a hundred-million mode.
Further, the adjusting the transmission mode of the gigabit ethernet card to the hundred mega mode includes:
adjusting the PHY chip of the gigabit Ethernet card to the hundred million mode; and
and adjusting the transmission rate of the PHY chip and the target gateway to be in a hundred-million mode.
For the convenience of understanding the present invention, the steps of the gigabit ethernet packet loss detection method according to the present embodiment will be described in detail below with reference to fig. 2.
The gigabit Ethernet packet loss detection method provided by the embodiment of the invention can be applied to embedded equipment such as an asynchronous multimedia playing box. Typically, an asynchronous multimedia play box, for example, includes an embedded processor. The android5.1 system is installed on the embedded processor. The android5.1 system is an open source operating system based on Linux. The gigabit ethernet network packet loss detection method provided by the embodiment of the present invention can detect the packet loss problem of the gigabit ethernet card, for example, through software installed on an Android system, such as a gigabit ethernet packet loss detection process. The gigabit ethernet packet loss detection process may be run in the user space of the user layer of the Android system, for example, and run in the background. As shown in fig. 2, the gigabit ethernet packet loss method according to the embodiment of the present invention compares two parameters of a detection data packet sent after networking and a received feedback data packet to determine and determine whether a gigabit ethernet card has a packet loss, and the specific process is as follows.
After the asynchronous multimedia playing box is started, for example, the gigabit ethernet packet loss detection process is automatically started, and the gigabit ethernet packet loss detection process is in a monitoring mode. Firstly, whether the gigabit Ethernet card has a network cable inserted and connected is detected. When no network cable is inserted, the gigabit Ethernet packet loss detection process is always in a monitoring mode to monitor the network cable insertion. When a network cable is inserted, the state change of the network card is acquired and reported to a system user layer so that the system user layer can acquire information of a gigabit Ethernet packet loss detection process and a system kernel communication interface (netlink). And after the user layer acquires the netlink information, analyzing and judging whether the equipment with the network change is the gigabit Ethernet card or not, and if so, acquiring whether the plugging network state of the gigabit Ethernet card is changed from down to up. If not, restarting the gigabit Ethernet packet loss detection process. Then, after the status is "up", the gigabit ethernet card performs network initialization, for example, to detect whether the gigabit ethernet card is in link mode with the target gateway, and whether the gigabit ethernet card acquires the IP address allocated by the target gateway. The target gateway here may be, for example, a PC, a network router, and other internetworking devices.
Then, the IP address of the target gateway connected to the gigabit ethernet card is obtained to facilitate communication with the target gateway to detect the packet loss.
And then, detecting whether the gigabit Ethernet card has packet loss. Specifically, the gigabit ethernet packet loss detection process continuously sends detection data packets to the target gateway for multiple times, for example, continuously sends the detection data packets for 100 times, and sends one data packet each time, according to the IP address of the target gateway; after receiving a detection data packet sent by embedded equipment, a target gateway compares a target IP address of the detection data packet with an IP address of the target gateway, and if the target IP address of the detection data packet is consistent with the IP address of the target gateway, the target gateway receives the detection data packet; and if the two are not consistent, discarding the detection data packet. And after receiving the detection data packet, the target gateway checks the detection data packet, extracts and processes a corresponding IP data packet, and finally constructs an ICMP response packet, namely a feedback data packet, and feeds the ICMP response packet back to the embedded equipment. The transmission process of the feedback data packet is the same as the process of sending the detection data packet to the target gateway by the embedded equipment. And the embedded equipment receives the feedback data packet sent by the target gateway. Here, the detection packet and the feedback packet are both ICMP packets. And finally, determining the packet loss rate by the gigabit Ethernet packet loss detection process according to the detection data packet and the feedback data packet. Specifically, the packet loss rate may be, for example, a ratio of a difference between the number of the detection packets and the number of the feedback packets to the number of the detection packets. And when the packet loss rate is not greater than a preset packet loss rate threshold value, judging that the gigabit Ethernet card has no packet loss, otherwise, judging that the gigabit Ethernet card has the packet loss. The preset packet loss rate threshold here may be, for example, 0, that is, the packet loss rate is not greater than 0, that is, no packet is lost, and if the packet loss rate is greater than 0, it indicates that a packet loss phenomenon exists, so that a problem that the video cannot be played may occur. Of course, the packet loss rate threshold may be other values. Further, after the gigabit ethernet packet loss detection process obtains the packet loss detection result, the packet loss detection result can be automatically output to remind the user to perform corresponding processing. The result output mode may be, for example, a mode of voice, light flashing, information pushing, and the like. Therefore, automatic detection of the packet loss of the gigabit Ethernet card is realized, the working efficiency is improved, and the labor cost is saved.
Further, the method is carried out. When the gigabit Ethernet card has packet loss, adjusting the transmission mode of the gigabit Ethernet card to a hundred-megabyte mode; specifically, the PHY chip of the gigabit ethernet card is adjusted to the hundred mega mode, and the transmission rates of the PHY chip and the target gateway are adjusted to the hundred mega mode. The hundred megabit mode is, for example, in the order of 100Mbps, i.e., the transmission rate of a gigabit ethernet card is reduced. Therefore, when the gigabit Ethernet card loses packets, the network transmission mode is automatically adjusted to the stable hundred megabyte mode, the problem that the video to be played cannot be played normally due to the packet loss of the gigabit Ethernet card is solved, and the user experience is improved.
When the gigabit Ethernet card has no packet loss, the resources are directly released, and the gigabit Ethernet packet loss detection process enters the sleep mode again. If the network cable is plugged in the gigabit Ethernet packet loss detection process, the gigabit Ethernet packet loss detection process also releases resources, and the gigabit Ethernet card with the plugged network cable is subjected to packet loss detection in a monitoring mode again.
In summary, the invention determines whether the acquired data packet is complete by sending the detection data packet and receiving the two parameters of the feedback data packet from the target gateway to determine whether the packet is lost, thereby solving the problem that the packet loss detection of the gigabit ethernet card of the embedded device in the prior art judges the packet loss manually, improving the detection efficiency and saving the labor cost. In addition, when packet loss is found, the transmission mode of the gigabit Ethernet card is automatically adjusted to a hundred megabyte mode, so that the problem of incomplete data transmission caused by the gigabit Ethernet packet loss due to the hardware problem with the Ethernet function and the performance problem of equipment (a router, a firewall and a switch) is solved, the video to be played is stored incompletely after being received, the video cannot be played, and bad experience is brought to a client. Further, the method indirectly avoids the return of goods and repair of customers, and reduces labor cost, maintenance cost and after-sale cost.
