Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a method for testing performance of a MoCA device according to an embodiment of the present invention. The following describes a performance testing method for MoCA equipment provided in an embodiment of the present application with reference to fig. 2.
The application provides a MoCA equipment performance test method, with the net gape of first equipment to be tested and the net gape of second equipment to be tested access first test terminal and second test terminal respectively, Ixchoriot test software control end has been installed to first test terminal, Ixchoriot test software distal end has been installed to second test terminal, first equipment to be tested passes through coaxial cable CoAX with the second equipment to be tested and is connected, as shown in figure 2, the method includes:
s110: the first test terminal sends a ping command to the second test terminal.
The first test terminal sends ping command to the second test terminal, at this time, the ping command will construct ICMP request data packet on the first test terminal, then ICMP protocol will give the data packet and target IP information to IP layer protocol, after IP layer protocol gets these information, source address, target address and other control information are constructed into IP data packet, after IP data packet construction, through ARP mapping table find out target IP correspondent MAC address, after getting second test terminal MAC address and first test terminal MAC, they are together given to data link layer, assemble into data frame, according to Ethernet media access rule, data frame is sent to the second test terminal, after second test terminal receives data frame, it will first check if its target MAC address is local, if yes, take out IP data packet in data frame, and after the IP layer protocol is checked, taking out the ICMP data packet and delivering the ICMP data packet to the ICMP protocol for processing to construct an ICMP response data packet which is sent back to the first test terminal, wherein within a certain time, if the first test terminal receives the response packet, the network between the first test terminal and the second test terminal is accessible, and if the response packet is not received, the network is not accessible.
S120: if the continuous transmission failure command is detected and the network utilization rate is 0%, the Link is judged to be lost and reconnection is carried out.
The Ping command has a parameter of time delay in the transmission process, so that the phenomenon of interruption and reconnection can occur, but the actual transmission is not interrupted under the condition, so that the Ping command and the network utilization rate are used for simultaneously judging, if a continuous transmission failure command is detected and the network utilization rate is 0%, the phenomenon of interruption and reconnection caused by time delay can be eliminated, and the Link is judged to be disconnected and reconnected; therefore, the two indications of the ping command and the network utilization rate in the application are mutually matched to judge whether the two indications are unavailable.
S130: and acquiring the test waveforms of the first device to be tested and the second device to be tested.
The instantaneous control end and the far end of the coaxial Link can not receive signals instantaneously, so that the waveform can drop rapidly in the gap, and then the waveform is restored to be stable after the coaxial Link is automatically reconnected.
S140: and if the test waveforms are stable after falling rapidly and the data difference between the data sending end TX and the data receiving end RX is more than 10^5, judging that the Link is lost and reconnecting.
When external interference information is received, the test waveform also has unstable fluctuation, so that whether a Link is really disconnected or not must be judged by combining the quantity of the receiving and sending packets, therefore, in the application embodiment, if the test waveform is rapidly recovered after falling, and the data difference between a data sending end TX and a data receiving end RX is more than 10^5, the external interference information can be eliminated, and the Link is judged to be disconnected and reconnected; therefore, in the present application, it is necessary to combine both the test waveform and the transmission/reception packet to determine the waveform.
A pair of devices of MoCA can simultaneously carry out two modes of uploading and downloading in the working process, so that an Ixchoriot (endpoint) software interface can be set to be a TX + RX bidirectional transmission mode, and a transient control end and a far end which coaxially drop Link can not receive signals instantaneously, so that a waveform can drop rapidly in the gap, and then the waveform is recovered to be stable after coaxial automatic reconnection. After monitoring abnormal waveforms from the networking, the method reads the conditions of receiving and sending packets on the physical layer of the PHY chip of the DUT and the MoCA line at the moment through a serial port (Debug port), and can judge that the Link drop phenomenon occurs at the moment when the coaxial line is subjected to a large amount of packet loss at the moment.
Coax (Clnk) represents the data transceiving condition on the coaxial Link, the transceiving packet per second is more than 10^5 calculated according to 1514 bytes, if the difference quantity between RX and TX reaches the magnitude order, and the test waveforms of Ixchoriot are combined, the test waveforms of the first device to be tested and the second device to be tested both rapidly drop and then recover stably, and the phenomenon that the Link is lost on the coaxial line can be judged.
In another embodiment, in order to monitor whether Link drop and reconnection occur in the system more intuitively, in the embodiment of the present application, a test terminal may be used to drop and whether an indicator of the MoCA device in the current state is normal, if the Link drop occurs, it indicates that information that the test loop has not been received occurs, and the loop is interrupted, and at this time, whether the indicator of the MoCA device in the current state is normal may be observed, specifically: if the first test terminal is disconnected and the indicator lamp of the first equipment to be tested is turned off, judging that the first equipment to be tested is disconnected and reconnected;
and if the second test terminal is disconnected and the indicator lamp of the second device to be tested is turned off, judging that the second device to be tested is disconnected and reconnected.
In another embodiment, it may also be determined that the first device under test loses Link and reconnects when the TCP address of the first test terminal is unavailable and the network utilization rate is 0% by monitoring whether an interface of "unavailable TCP address" is popped up by Ixchariot test software and monitoring data of a parameter of network utilization rate at the same time;
and when the TCP address of the second PC end is unavailable and the network utilization rate is 0%, judging that the second device to be tested is disconnected and reconnected.
Because the connection rate of the network port is stable and unchangeable, the observation data from the control end of the Ixchoriot is stable and has no fluctuation, so that whether the phenomenon of Link drop occurs on the coaxial MoCA equipment can be judged through abnormal phenomena such as drop lines or large-amplitude fluctuation of waveforms, and the test result is more accurate.
According to the technical scheme, the performance test method of the MoCA equipment can monitor the coaxial connection state of the MoCA equipment in real time, timely discover the phenomenon that the Link is discontinuously removed in the test process, ensure the stability of data transmission and enable test data to be more accurate.

Because the connection speed of the network port is stable and unchangeable, the data observed from the Ixchoriot control end is stable and has no fluctuation, so that whether the Link drop phenomenon occurs on the coaxial line of the MoCA equipment can be judged through the abnormal phenomena such as drop line or large-amplitude fluctuation, and the test result is more accurate.
