Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
The terms "first" and "second" in the embodiments of the present invention are used to distinguish some features, which are set for convenience of understanding and are not limited in other aspects.
The method for determining the network condition as shown in fig. 1 comprises the following steps:
s101: acquiring a first uplink packet loss rate, a downlink packet loss rate and other uplink packet loss rates; the first uplink packet loss rate is the packet loss rate of the client uploading the video stream to the server, the downlink packet loss rate is the packet loss rate of the client downloading the video streams of other members in the video room from the server, and the other uplink packet loss rates are the packet loss rates of the client uploading the video streams of other members in the video room to the server; the video room is a virtual video room that the client user enters through the client.
There may be two or more members in the video room, and the number of the other uplink packet loss rates may correspond to the number of the other members in the video room, and may be one or more. The other members in the video room refer to the user members corresponding to other clients except the user member corresponding to the client. When two members in a video room perform video chat, one other member in the video room is provided, and the other uplink packet loss rate is one; when three members in a video room are in video chat, two other members in the video room are in the video chat, and the other uplink packet loss rate can be one or two; when more than three members of the video room are in video chat, more than two other members in the video room are in video chat, and the other uplink packet loss rate can be one or two or more.
As shown in fig. 2, the first uplink packet loss rate statistics method may include:
s1011: the server or the client defines a statistical period T1 of a data packet; that is, the server counts the packet loss rate once when the client sends T1 data packets;
s1012: the client numbers the sent data packets and then sends the data packets to the server according to the numbering sequence;
s1013: after receiving a data packet sent by a client, a server judges the number of the data packet; if the server receives the first data packet with the number n1, the server records the number n1 of the data packet;
s1014: when the server judges that the number of the received data packets is greater than or equal to n1+ T1-1, counting the number of the received data packets in the period, and calculating the first uplink packet loss rate in the period;
s1015: if the server judges that the number of the received data packet is more than n1+ T1-1, the received data packet is used as the start of the next statistical period; if the server judges that the number of the received data packet is equal to n1+ T1-1, the next received data packet is used as the start of the next statistical period; and calculating the first uplink packet loss rate in each period according to the circulation.
T1 may be a positive integer such as 10, 30, 55, 80, 100, 200, or 500, and the number may be a natural number in the order of 0, 1, 2, 3, or 4, starting from 0, or may be a number starting from another natural number.
Specifically, let T1 be 10, that is, the server counts the packet loss rate once every time the client sends 10 data packets; assuming that the number of the first data packet is 10 (the number of the data packet sent by the client is 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, etc.), when the server receives the data packet, the number of the data packet is recorded; and when the server judges that the number of the received data packets is greater than or equal to 19, counting the number of the received data packets, and calculating the first uplink packet loss rate in the period. If the server judges that the number of the received data packet is larger than 19, the received data packet is used as the start of the next statistical period; if the server judges that the number of the received data packet is equal to 19, taking the next received data packet as the start of the next statistical period; and calculating the first uplink packet loss rate of each period according to the circulation.
Further, taking the first period as an example, when the server receives the first data packet, the server records the number 10 of the data packet. If the server receives the data packet number 19, the server starts to count the received data packets, and if the number of the received data packets is 10, 14, 15, 17, 18, 19, the lost data packets are 11, 12, 13, 16, and the packet loss rate in the counting period is 4/10; if the server receives the data packet number 18 and then directly receives the data packet number 20, the server starts to count the received data packets, and if the number of the received data packets is 10, 14, 15, 17, and 18, the number of the lost data packets is 11, 12, 13, 16, and 19, and the packet loss rate in this counting period is 5/10.
Further, after the server receives the data packet No. 20, the server takes the received data packet as the start of the next statistical period, and when the server judges that the number of the received data packet is greater than or equal to 29, the server performs statistics on the received data packet and calculates the packet loss rate of the period. If the server receives the number 18 data packet and directly receives the number 21 data packet, the server takes the received number 21 data packet as the start of the next statistical period, and when the server judges that the number of the received data packet is greater than or equal to 30, the server performs statistics on the number of the received data packets and calculates the packet loss rate of the period. If the server receives the data packet number 30, the server starts to count the received data packets, and assuming that the numbers of the received data packets are 21, 24, 25, 27, 28, 29 and 30, the lost data packets are 22, 23 and 26, and the packet loss rate in this counting period is 3/10.
The method for counting the downlink packet loss rate may be similar to the method for counting the first uplink packet loss rate, and specifically may include:
step 1: the server or the client defines a statistical period T2 of a data packet; that is, the client side counts the packet loss rate once when the server sends T2 data packets;
step 2: the server numbers the sent data packets and then sends the data packets to the client according to the numbering sequence;
and step 3: after receiving a data packet sent by a server, a client firstly judges the number of the data packet; if the client receives the first data packet with the number n2, the client records the number n2 of the data packet;
and 4, step 4: when the client judges that the number of the received data packets is greater than or equal to n2+ T2-1, counting the number of the received data packets in the period, and calculating the first uplink packet loss rate in the period;
and 5: if the client judges that the number of the received data packet is larger than n2+ T2-1, the received data packet is used as the start of the next statistical period; if the client judges that the number of the received data packet is equal to n2+ T2-1, taking the next received data packet as the start of the next statistical period; according to the circulation, calculating the downlink packet loss rate in each period;
t2 may be a positive integer such as 10, 30, 55, 80, 100, 200, or 500, and the number may be a natural number in the order of 0, 1, 2, 3, or 4, starting from 0, or may be a number starting from another natural number.
The other uplink packet loss rates are packet loss rates of the clients of other members in the video room uploading the video streams to the server, and are counted in the process that the server receives the video streams uploaded by the clients of other members in the video room, and the counting method can be the same as the counting method of the first uplink packet loss rate, but is different from the client object.
The obtaining of the first uplink packet loss rate, the downlink packet loss rate, and the other uplink packet loss rates may specifically be that the client obtains the first uplink packet loss rate and the other uplink packet loss rates from the server, and obtains the downlink packet loss rate from the inside of the client.
S102: and judging the network condition of the client and the network conditions of the clients of other members in the video room according to the acquired first uplink packet loss rate, the acquired downlink packet loss rate and the acquired other uplink packet loss rates.
The network status of the client and the network status of other members in the video room may be divided into a good level and a poor level, or divided into a good level, a medium level and a poor level, or divided into other levels.
Specifically, a parameter m can be set, wherein m is more than 0 and less than 1;
if the first uplink packet loss rate is greater than m, judging that the network condition of the client is poor;
if the first uplink packet loss rate is less than or equal to m and the downlink packet loss rate is greater than m, determining that the network condition of the client is poor;
and if the first uplink packet loss rate is less than or equal to m and the downlink packet loss rate is less than or equal to m, judging that the network condition of the client is good.
If the other uplink packet loss rates are larger than m, judging that the network conditions of other member clients corresponding to the uplink packet loss rate in the video room are poor;
and if the other uplink packet loss rate is less than or equal to m, judging that the network condition of other member clients corresponding to the uplink packet loss rate in the video room is good.
The method for judging the network condition can timely and accurately judge the network condition of the client and the network conditions of the clients of other members in the video room in the process of video chat of the user, if the network is blocked, people in the video chat can quickly and accurately know which party of the network has the problem, so that the user can conveniently and quickly solve the phenomenon of network blockage, and the experience effect of the video chat of the user is improved.
