As shown in fig. 1, in one embodiment, an intelligent primary-secondary relationship establishing method of a Mesh system is provided, which specifically includes the following steps:
S101, establishing a primary-secondary relation between routes to form a plurality of multi-branch tree networks taking a main route as a starting point;
S102, for each main route, generating a main data packet, dividing the main data packet into a plurality of sub-data packets according to the number of next-stage sub-routes connected with the main route, and respectively transmitting the sub-data packets to each connected next-stage sub-route;
s103, receiving a plurality of sub-data packets which are transmitted along the original uplink by the sub-route;
S104, calculating the downlink speed V 1, the uplink speed V 2, the downlink transmission time deviation T 1, the uplink transmission time deviation T 2 and the loss rate a of the main data packet of the main route according to each sub data packet received by the main route;
S105, obtaining the channel quality value of the main route according to V 1、V2、T1、T2 and a;
S106, determining a main route communicated with the light cat as an exit route according to the channel quality value of each main route;
S107, judging whether a transaction signal of a sub-route is received, if yes, exchanging a sub-route generating the transaction signal with a sub-parent relation of the sub-route connected with the sub-route, and executing the S102-S105 on a main route communicated with a light cat once by exchanging the sub-parent relation each time;
s108, determining a primary-secondary relation of exchange according to the channel quality value of the main route obtained after each exchange and carrying out exchange update on the multi-way tree network;
S109, executing S102-S108 once every other preset period.
In this embodiment, in S101, there are various ways of establishing routes, and the originating terminal may be used as a parent node, the connected terminal may be used as a child node, and a primary-secondary relationship between routes may be established; the primary-secondary relationship between the routes can also be determined according to the order set by the user, for example, different grades are set for the routes, and the high-grade route is used as the primary node of the low-grade route to establish the connection relationship between the two. After the networking state is established, the routes connected with the optical cat are main routes, and the number of the main routes can be multiple, and the connection does not represent communication. The next-level routes connected with the main route are sub-routes, the number of the next-level routes connected with the sub-routes can be multiple, and the number of the next-level routes connected with the sub-routes can be multiple. In an actual networking process, there are typically no more than five sub-routes connected by one route. The number of networking stages is typically no more than three, which can cause the network to be greatly attenuated or even unusable. For a multi-drop tree network with a primary route as a starting point, the primary route is the primary route, the secondary route is a sub-route connected to the primary route, the tertiary route is a sub-route connected to the sub-route of the secondary route, and so on.
In this embodiment, the primary route may be a sub-route in the multi-drop tree network starting from another primary route. For example, one route is a primary route in a multi-drop tree network that starts with the primary route itself, but is a sub-route in a multi-drop tree network that starts with other primary routes. Depending on whether the route has communication with the light cat, there is a primary route that communicates with the light cat, and there is a secondary route that does not communicate with the light cat.
In this embodiment, in S102, equally dividing the main data packet means equally dividing the data amount of the main data packet. For example, the main data packet is 10M, and the main route is connected with 2 sub-routes, that is, 2 sub-routes in the second level route of the multi-tree network with the main route as the starting point, so that the data volume of the equally divided sub-data packet is 5M. The main route transmits sub-packets of 5M to each sub-route separately.
In this embodiment, in S103, the sub-route received by the main route is from the sub-route of the last stage along the sub-packet transmitted on the original route. For example, a multi-tree network with a main route as a starting point has 3 routes, the first route is the main route, the second route has 2 sub-routes, each sub-route has 2 sub-routes of the next level, so the third route has 4 sub-routes, the data volume of the sub-data packet received by the main route is 4, and the data volume is respectively from the 4 sub-routes of the third route. And for a link corresponding to one sub-route of the third-level route, after the downlink transmission of the link is finished, namely the first-level route transmits the sub-data packet downwards to the second-level route, the second-level route transmits the sub-data packet downwards to the third-level route, if the fourth-level route does not exist, the third-level route transmits the sub-data packet upwards to the second-level route, and the second-level route receives the sub-data packet transmitted upwards by the third-level route and then transmits the sub-data packet upwards to the first-level route. Since the uplink transmission is carried out along the original path and the relation between the uplink transmission and the previous-level path is 1 to 1, the sub-data packets of the uplink transmission do not need to be evenly divided. In transmitting data, one sub-route has only one primary route or sub-route of the previous stage, but there may be a plurality of sub-routes of the next stage.
In this embodiment, S104, the downlink rate V 1 is an average value, the main data packet is equally divided into a plurality of sub-data packets and transmitted to different sub-routes, where different downlink rates exist, and the sub-routes equally divide the received sub-data packet to different sub-routes of the next stage, where different downlink rates exist. Therefore, the downlink rate V 1 refers to the average value of the downlink rates of all the sub-packets in the process that the main data packet reaches the final stage of sub-route; the uplink rate V 2 is the same. One downlink time exists in every two connected routes, a plurality of downlink times exist, and the downlink transmission time deviation T 1 is the deviation degree of each downlink time and the minimum downlink time; the uplink transmission time offset T 2 is the same. The loss rate of the main data packet refers to the ratio of the amount of lost data to the amount of data of the main data packet. The data in the sub-data packet received by the main route is transmitted from the main route to the sub-route of the last stage, and is transmitted back to the main route from the sub-route of the last stage.
In this embodiment, in S105, the channel quality value is used to determine the network quality of the multi-tree network starting from the primary route, and the larger the channel quality value is, the better the network quality of the multi-tree network starting from the primary route is.
In this embodiment, in S106, the primary route having the largest channel quality value is determined as the primary route for communication with the optical cat, i.e., the egress route. The egress route is a main route for communicating with the optical cat, only one of which is determined, and the other main routes are used as a sub-route of the multi-tree networking of the main route.
In this embodiment, in S107, the occurrence of the transaction signal of a sub-route is various, for example, a certain sub-route is disconnected, the sub-route is not checked by the route of the upper stage of the sub-route, and the transaction signal of the sub-route is sent; for example, interference of environmental factors or change in transmission position of a certain sub-route causes weakening of signal processing capability of the sub-route, and a transaction signal of the sub-route is transmitted.
In this embodiment, in S107, the primary-secondary relationship between the primary route generating the transaction signal and the secondary route connected thereto is essentially exchanged, and the positions of both routes in the multi-tree network are exchanged, and the routes connected to the two exchanged routes also need to be changed accordingly. For example, the main route is connected with the sub-route 1, the sub-route 1 is connected with the sub-route 2 and the sub-route 3, and the sub-mother relation between the sub-route 1 and the sub-route 2, namely, the sub-route 2 is connected with the sub-route 1 is exchanged, so that the multi-branch tree networking becomes that the main route is connected with the sub-route 2, and the sub-route 2 is connected with the sub-route 1 and the sub-route 3.
In this embodiment, in S107, exchanging the primary-secondary relationship between the primary route generating the transaction signal and the primary route connected thereto, each time exchanging the primary-secondary relationship is performed once on the primary route communicating with the optical cat S102-S105, including:
s901, selecting a sub-route connected with the sub-route generating the abnormal signal, and disconnecting the connection relationship between the selected sub-route and the sub-route generating the abnormal signal;
s902, exchanging all connection relations of the selected sub-route and the sub-route generating the abnormal signal;
s903, establishing a connection relationship between the selected sub-route and the sub-route generating the abnormal signal by taking the selected sub-route as a parent route and the sub-route generating the abnormal signal as the sub-route;
s904, performing S102-S105 once for the main route of communication with the light cat;
S905, restoring the connection relation between the routes after exchange to the connection relation between the routes before exchange, and selecting one unselected sub-route from the sub-routes connected with the sub-routes generating the abnormal signals to execute S901-S904;
S906, repeating S905 until all the sub-routes connected to the sub-route generating the transaction signal are selected.
In this embodiment, in S108, if there are a plurality of exchange relationships, the exchange route with the highest channel quality value of the main route obtained after exchange is determined as the primary-secondary relationship of the exchange, and it is ensured that the channel quality value of the main route obtained after exchange is higher than before exchange. If there is only one exchange relation and the channel quality value of the main route obtained after exchange is lower than that before exchange, then exchange can be carried out to the next stage, if there is no next stage, the original primary-secondary relation is restored. If the sub-route is still present after the exchange, then the route exchange may be to the next level or peer.
In this embodiment, in S109, the preset period may be a multiple of the average time period used for running out S102-S108, or may be a manually set time period, for example, 12 hours.
The intelligent primary-secondary relation establishing method of the Mesh system provided by the embodiment of the application forms a plurality of multi-branch tree networking taking a main route as a starting point by establishing primary-secondary relations among routes; for each main route, generating a main data packet, dividing the main data packet into a plurality of sub-data packets according to the number of next-stage sub-routes connected with the main route, and respectively transmitting the sub-data packets to each connected next-stage sub-route; receiving a plurality of sub-data packets which are transmitted along the original route in an uplink manner by a sub-route; calculating the downlink speed V 1, the uplink speed V 2, the downlink transmission time deviation T 1, the uplink transmission time deviation T 2 and the loss rate a of the main data packet of the main route according to each sub data packet received by the main route; obtaining a channel quality value of the main route according to V 1、V2、T1、T2 and a; determining a main route communicated with the optical cat as an exit route according to the channel quality value of each main route; judging whether a transaction signal of a sub-route is received, if yes, exchanging a sub-route generating the transaction signal with a sub-and-mother relation of the sub-route connected with the sub-route, and executing more than one step on a main route communicated with a light cat by exchanging the sub-and-mother relation each time; determining a primary-secondary relation of exchange according to the channel quality value of the main route obtained after each exchange and carrying out exchange update on the multi-branch tree network; repeating the above steps every other preset period. The application determines the channel quality value of the main route by transmitting the sub-data packet downwards to each main route and receiving the sub-data packet transmitted upwards to each sub-route; determining a main route communicated with the optical cat as an exit route according to the channel quality value of each main route, and adjusting the communication link to the communication link with the best network quality so as to optimize the network quality; exchanging the primary-secondary relation of the primary route generating the abnormal signal and the secondary route connected with the primary route generating the abnormal signal, calculating the channel quality value of the primary route communicated with the optical modem once by exchanging the primary-secondary relation each time, determining the primary-secondary relation of one exchange according to the channel quality value of the primary route obtained after each exchange, exchanging and updating the multi-branch tree network, and adjusting the position of the secondary route generating the abnormal signal to optimize the network quality of the secondary route. Whereby the network quality can be self-adjusted to optimize the network quality.
In one embodiment, the method equally divides the main data packet into a plurality of sub data packets according to the number of the sub routes connected by the main route on the multi-tree network and transmits the sub data packets to each connected sub route, and then further comprises:
S201, judging whether the sub-route of the received sub-data packet has the sub-route connected with the next stage, if so, dividing the received sub-data packet into a plurality of sub-data packets of the next stage according to the number of the sub-routes connected with the next stage, and respectively transmitting the sub-data packets to each sub-route connected with the next stage, otherwise, not operating;
S202, repeating S201 until the sub-route of the received sub-data packet has no sub-route connected to the next stage.
In this embodiment, since the uplink transmission of the sub-packet starts from the sub-route of the last stage, it is necessary to determine whether the sub-route receiving the sub-packet has the sub-route connected to the next stage, and if so, the sub-packet needs to be equally divided into several sub-packets for downlink transmission until the sub-route receiving the sub-packet has no sub-route connected to the next stage. For example, the main data packet is 10M, and the main route is connected with 2 sub-routes, that is, 2 sub-routes in the second level route of the multi-tree network with the main route as the starting point, so that the data volume of the equally divided sub-data packet is 5M. The main route transmits sub-packets of 5M to each sub-route separately. All the 2 sub-routes have 2 next-level sub-routes, namely the third-level route has 4 sub-routes, and if no data loss exists, the sub-data packet of 5M is equally divided into 2 sub-data packets of 2.5M. If the fourth-level route does not exist, downlink transmission is not performed any more, and uplink transmission is performed from the third-level route.
In one embodiment, the sub-routes respectively transmitted to the next stage connection include:
S301, judging whether a connection port is idle, if yes, judging whether idle time reaches preset time, and if yes, transmitting the idle time to a next-stage connected sub-route corresponding to the connection port;
S302, repeating S301 until the idle time reaches the preset time if the idle time does not reach the preset time;
S303, if the connection port is not idle, repeating S301-S302 until the connection port is idle;
S304, in the transmission process of the sub-data packet, judging whether the transmission data of the network end appears, if so, stopping the transmission of the sub-data packet, and executing S301-S303.
In this embodiment, since the routes in the multi-drop tree network are in a normal operation state, it is necessary to select an idle time for testing. Since data is transmitted through the connection port, the route is idle when the connection port is idle.
In this embodiment, the preset time may be slightly longer than the data transmission interval of the network, so that it is ensured that the connection port is not misjudged to be in the idle state due to the data transmission interval of the network. For example, the data transmission interval of the network is 0.1ms, and the preset time may be set to 0.2ms.
In this embodiment, in the process of transmitting the sub-packet, transmission data of the network end appears, and transmission of the sub-packet is stopped. If the sub-data packet is not completely transmitted, the sub-route of the next stage is required to discard the received partial sub-data packet and notify the main route at the same time, and wait for the next connection port to be idle and then re-transmit the sub-data packet.
In one embodiment, calculating the downstream rate V 1 and the upstream rate V 2 of the primary route according to each sub-packet received by the primary route includes:
For each sub-data packet received by the main route, determining the downlink time length b i and the uplink time length c i of the sub-route of the sub-data packet in each stage;
determining the data quantity A i of the sub-data packet received by the sub-route of each stage before downlink transmission;
Determining the data quantity B i of the sub-data packet before uplink transmission of the sub-route of each stage;
From the following components Obtaining the downlink rate d k of the sub-data packet;
From the following components Obtaining the downlink rate V 1 of the main route;
From the following components Obtaining the uplink rate e k of the sub-data packet;
From the following components Obtaining the uplink rate V 2 of the main route;
wherein i is the number of routing stages where the sub-route is located, i is counted from 2, N is the total number of the sub-routes, k is the number of the sub-data packets received by the main route, k is counted from 1, and N is the total number of the sub-data packets received by the main route.
In this embodiment, the first level route is the main route, and the second level route has sub-routes, so i counts from 2.
In this embodiment, since data may be lost in transmission, the calculation uses the data amount of the sub data before transmission, not the data amount of the received sub data.
In this embodiment, for each sub-packet received by the main route, only one sub-route is corresponding to each level of sub-route, so the data amount a i of the sub-packet received by each level of sub-route before downlink transmission, that is, the data amount of the sub-packet after the sub-packet received by the previous level of route is equally divided.
In this embodiment, if there are multiple sub-routes, there are multiple sub-packets, i.e. there are multiple downstream rates, so it is necessary to calculate an average downstream rate to represent the downstream rate that occurs during all downstream transmissions. The uplink rate is the same.
In this embodiment, the downlink rate d k of a sub-packet is calculated first, and the downlink rates of the sub-packets are different between routes of each level, so d k is an average value, and then the average value between d k of all the sub-packets is calculated to obtain the downlink rate V 1 of the main route. The uplink rate is the same.
In this embodiment, for example, the second level route has a sub-route 1, the third level route has a sub-route 2 and a sub-route 3, and the sub-route 2 and the sub-route 3 are respectively connected to the sub-route 1, and only three levels of routes are provided. For sub-packets requiring uplink transmission from sub-route 2 to sub-route 3, the downlink rate of the data between the main route and sub-route 1 is essentially the downlink rate of the sub-packets transmitted from the main route to sub-route 1, i.e. for sub-packets requiring uplink transmission from sub-route 2 to sub-route 3, the first downlink transmission rate of the sub-packets is the same.
In one embodiment, the determining the downlink duration b i and the uplink duration c i of the sub-route of the sub-packet at each stage includes:
acquiring all time stamps of the sub data packet, dividing all time stamps into a time group according to a time sequence, and counting the number D of the time groups;
subtracting the previous time stamp from the next time stamp to obtain a transmission duration for each group of time groups;
according to the front The transmission duration of the group time group determines the downlink duration b i of the sub-route of the sub-data packet at each stage;
According to the back The transmission duration of the group time group determines the uplink duration c i of the sub-route of the sub-packet at each stage.
In this embodiment, each route starts data transmission and after receiving the complete data, a time stamp is added to the data packet, and the process is performed spontaneously. The main route can calculate the downlink time length and the uplink time length of each sub-data packet in each level route according to the attached time stamp on the sub-data packet.
In this embodiment, data is transmitted before being received, so the transmission time is before the reception time. Each time group represents the duration of a sub-packet transmission between two routes.
In this embodiment, since the sub-packet is first transmitted to the sub-route of the last stage, and the sub-route of the last stage is transmitted to the main route, the time group includes the duration of the downlink transmission and the duration of the uplink transmission, and the number of the time groups of the downlink transmission is the same as the number of the time groups of the uplink transmission. For example, if there are 4 time groups in the sub-packet received by one main route, the 1 st time group is the transmission time length of the main route for downlink transmission of the sub-route of the second-level route, the 2 nd time group is the transmission time length of the sub-route of the second-level route for downlink transmission of the sub-route of the third-level route, the 3 rd time group is the transmission time length of the sub-route of the third-level route for uplink transmission of the sub-route of the second-level route, and the 4 th time group is the transmission time length of the sub-route of the second-level route for uplink transmission of the main route.
In one embodiment, calculating the downlink transmission time deviation T 1 and the uplink transmission time deviation T 2 of the main route according to each sub-packet received by the main route includes:
Determining the minimum downlink duration b min according to the downlink duration of all the sub-data packets;
Determining the minimum uplink length c min according to the uplink lengths of all the sub-data packets;
For each sub-packet received by the primary route, a packet is sent by Obtaining the downlink transmission time deviation f k of the sub-data packet;
From the following components Obtaining a downlink transmission time deviation T 1 of the main route;
From the following components Obtaining the uplink transmission time deviation g k of the sub-data packet;
From the following components Obtaining a downlink transmission time deviation T 1 of the main route;
wherein m i is the number of sub-routes in the ith level of route.
In this embodiment, for example, the second level route has 1 sub-route and the third level route has 2 sub-routes, and then the data volume of the sub-data packet downstream transmitted from the main route to the second level route is 2 times that of the sub-data packet downstream transmitted from the second level route to the third level route, and the time is 2 times that of the sub-data packet downstream transmitted from the second level route to the third level route, so that the transmission time required in the sub-data packet downstream from the main route to the second level route is 1/2 of that of the original sub-data packet, namely。
In this embodiment, the uplink transmission does not involve the sub-packet combining process, so that the uplink data does not need to be processed.
In one embodiment, calculating the loss rate a of the main data packet according to each sub data packet received by the main route includes:
Determining the data quantity C k of each received sub-data packet;
From the following components Obtaining the loss rate a of the main data packet;
wherein k is the serial number of the sub-data packets received by the main route, k is counted from 1, N is the total number of the sub-data packets received by the main route, and E is the data volume of the main data packet.
In this embodiment, N is the total number of sub-packets received by the primary route, and is also the number of sub-routes of the last-stage route.
In one embodiment, the obtaining the channel quality value of the primary route according to V 1、V2、T1、T2 and a includes:
From the following components Obtaining an average transmission rate V 3 of the main route;
From the following components Obtaining an average transmission time deviation T 3 of the main route;
From the following components Obtaining a channel quality value of the primary route;
Where x 1 is the transmission coefficient, y 1 is the rate factor, y 2 is the time factor, and y 3 is the actual transmission factor.
In this embodiment, since the downlink rate is generally 10 times the uplink rate, x 1 may be set to 10 in order to reduce the influence of the downlink rate on the uplink rate.
In this embodiment, all uplink rates are multiplied by x 1 and then compared with all downlink rates, the maximum rate is selected as V max, the transmission time deviation T max,y1 for beating is selected from the downlink transmission time deviation and the uplink transmission time deviation as the ratio of Y 1 to V max, and Y 2 is the ratio of Y 2 to T max. The value of Y 1、Y2 and Y 3 added together is 1. The values of Y 1、Y2 and Y 3 may be set to 1/3. The values of Y 1、Y2 and Y 3 may also be determined according to the actual requirements. For example, where the actual demand requires a fast transfer rate, then the value of Y 1 can be set larger, only to ensure that the sum of Y 1、Y2 and Y 3 is 1.
