Description
Technical Field
The invention relates to the technical field of network communication, in particular to a single transmission method using a signal linked list.
Background
In the current research and use of network communication, there are three main communication modes: unicast, broadcast, multicast.
Unicast refers to one-to-one communication between an information transmitting end (hereinafter, referred to as a transmitting end) and an information receiving end (hereinafter, referred to as a receiving end). Because the sending end and the receiving end directly transmit information, the integrity of the information is quite complete, but if a plurality of receiving ends request the same information data, the sending end needs to send data information for a plurality of times one by one, which not only occupies processor resources and wastes bandwidth, but also hardly ensures network transmission quality if the receiving ends in the network are too many (as shown in fig. 3).
The broadcast means that the sending end only sends the information flow once through the intermediate node, and the intermediate node copies the information flow and sends the information flow to all receiving ends in the range in a unified manner. The method has the advantages that the sending end only needs to send the information once to cover the receiving end in a certain range, but meanwhile, the receiving end which does not need the information in the range can receive the information, so that redundancy of information data transmission is caused, and unplanned transmission pressure is caused to intermediate nodes and lines in the range (as shown in fig. 4).
On the basis, researchers have researched multicasting, which includes part of receiving ends needing information in a specific group when the receiving ends are used, the group uses the same multicasting address, when the sending end sends the information to the multicasting group, the intermediate nodes closest to the receiving ends copy and send the information data to all the receiving ends in the multicasting group according to the number of the receiving ends, and other receiving ends outside the multicasting group can not receive the information.
(as shown in FIG. 5)

Example 1
In the current research and use of network communication, there are three main communication modes: unicast, broadcast, multicast. All three of these ways put some pressure on the transmission of the intermediate nodes and lines.
Therefore, in order to solve the disadvantages of the three transmission modes, an embodiment 1 of the present invention provides a single transmission method using a signal chain table, including:
arranging a sending end and a plurality of receiving ends in the same linked list, and sequentially connecting the sending end and the receiving ends in a communication way;
the transmitting end transmits signal data to the receiving ends, and the signal data sequentially passes through each receiving end in the linked list. The invention can effectively save the bandwidth of a network communication transmission line, reduce the consumption of the bandwidth, save the resource space of an intermediate processor and reduce the information redundancy, thereby saving the process of copying and distributing signals by the processor, shortening the path of the signals from the transmitting end to the receiving end, reducing the amount of information lost on the way and enabling the transmission of the signals to be quicker and more complete, and the single-shot signal chain table is a communication transmission method with simple structure, lower cost and high transmission speed.
Preferably, in the transmission method using a single signal linked list provided in embodiment 1 of the present invention, each receiving end includes an input node and an output node; the sending end sends signal data to each receiving end through the input node; and the receiving end replies a signal to the transmitting end through the output node. In this embodiment 1, client software at a sending end issues a node signal linked list command, where a node includes an input node corresponding to the signal and output nodes corresponding to all receiving ends that need the signal. The signal data is forwarded once every packet byte received.
Preferably, in the transmission method using a single transmission of a signal chain table provided in embodiment 1 of the present invention, as shown in fig. 1, a transmitting end transmits signal data to a receiving end in an interrogation manner; the sending end sequentially inquires according to the arrangement sequence of the receiving end (the arrangement sequence is the sequence of receiving signals by the receiving end, the frequency of inquiry is once per frame or N frames, and the actual condition depends on the switching efficiency and the actual effect);
the step that the sending end sends the signal data to the receiving end and the signal data sequentially passes through each receiving end in the linked list is as follows:
step S1: a sending end sends a query signal to a receiving end;
step S2: the receiving end replies a signal to the transmitting end;
and step S3: the sending end sends signal data to the receiving end and inquires the next receiving end until the inquiry is finished.
For example: as shown in fig. 1, one signal a needs to be displayed on the outputs 1,2,3,4, four nodes. Then the { SignalChain:1,2,3,4} needs to be sent to the input nodes and the four output nodes 1,2,3, 4. At this time, 1,2,3 and 4 represent the IP addresses of four output nodes, and for convenience of expression, the IP addresses are sorted according to the order of the IP sizes. Before each transmission, according to the last inquiry reply, finding the next effective stage in sequence and transmitting data.
Example 2
In the transmission method using a single linked list provided in embodiment 1 of the present invention, the step "the sending end sends signal data to the receiving end, and the signal data sequentially passes through each receiving end in the linked list" further includes a second condition, as shown in fig. 2, which specifically is:
step N1: a sending end sends an inquiry signal to a receiving end;
and step N2: the receiving end does not reply the signal;
and step N3: the sending end inquires the next receiving end according to the arrangement sequence of the receiving ends until the inquiry is finished.
For example: as shown in fig. 2, one signal a needs to be displayed on the outputs 1,2,3,4, four nodes. Then the SignalChain:1,2,3,4 would need to be sent to the input nodes and to the four output nodes 1,2,3, 4. At this time, 1,2,3, and 4 represent IP addresses of four output nodes, at this time, the node 2 does not reply a signal and is considered to be a dropped line, and the dropped line is not displayed on the node 2, so that signal data sent by a sending end can automatically skip the node 2, and the node 3 is directly queried from the node 1 for convenient expression, and at this time, the nodes are sorted according to the IP size sequence.
Because the situation that the receiving end cannot receive the signal inevitably occurs in signal transmission, the sending end sends a query to the receiving end no matter whether the receiving end can receive the signal or reply the signal, and the receiving end does not reply, so that the sending end skips the receiving end to carry out the next query, and the transmission efficiency of other nodes cannot be influenced.
Preferably, in the transmission method using a single signal linked list provided in embodiment 1 of the present invention, the steps N1 to N2 specifically include:
when one of the receiving ends does not reply the signal, the sending end sends a second inquiry signal to the receiving end;
if the receiving end replies the signal, sending data according to the step S3;
or when one of the receiving ends does not reply the signal, the sending end sends a second inquiry signal to the receiving end;
and if the receiving end does not reply the signal for the second time, the node of the receiving end is disconnected and the operation is carried out according to the step N3.
In this embodiment 1, any receiving end only needs to reply once, and can regard the node as recovering connection, and only needs to reply twice continuously to be taken as a dropped connection.
Preferably, in the transmission method using a single signal linked list provided in embodiment 1 of the present invention, when a node in the linked list that is disconnected recovers connection, the node is automatically arranged at the end of the linked list, and the transmission method is performed according to steps S1 to S3. In this embodiment 1, when the node recovers the connection, it may be considered that the node can reply the signal to the sending end, that is, the node may proceed according to steps S1 to S3, in addition, the receiving end may receive the reply signals sent by 2 or more nodes at the same time, and the receiving end may also complete the packet and send signal data to all the receiving ends that send the reply signals at the same time.
Preferably, in the transmission method using a single signal linked list provided in embodiment 1 of the present invention, when a receiving end is added to the linked list, the receiving end is automatically connected to the end of the linked list and performed according to steps S1 to S3 or steps N1 to N3. In this embodiment 1, a new receiving end added may have a situation of no reply to the linked list, and therefore whether the two situations are replied or not needs to be considered, no matter whether the node is recovered or the new receiving end is added, signal transmission between other receiving ends and the sending end on the linked list cannot be affected, the number of nodes can be increased or reduced at any time through the setting, and input and output of other nodes are not affected, and the receiver can be intelligently handled for sudden disconnection and recovery, thereby increasing flexibility of the communication network.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the specification and drawings, or any other related technical fields, are all included in the scope of the present invention.
