Data be sent to corresponding subscriber；
Publisher, subscriber in the system compatible udp protocol and Transmission Control Protocol simultaneously, according to network healthy shape in real time
Condition, it is autonomous that transport layer is selected to transmit data, i.e., when system is in " health status ", publisher using udp protocol or Transmission Control Protocol
Data transmission between subscriber uses udp protocol；When system is in " unhealthy status ", between publisher and subscriber
Data transmission use Transmission Control Protocol.
Optionally, heartbeat detection mechanism is introduced, heartbeat detection mechanism is by periodically sending heartbeat packet to other nodes
And the mode of wait-for-response carrys out the health status of detection system.
Optionally, the heartbeat detection mechanism is to push away model or draw model.
Optionally, heartbeat detection is periodically carried out, the ratio that heartbeat packet is properly received is calculated, system is judged according to the ratio
Health status.
Optionally, comprising the following specific steps
Step 101: periodically carrying out heartbeat detection, calculate the ratio that heartbeat packet is properly received；
Step 102: according to " health status " of the ratio-dependent system that heartbeat packet is properly received；
Step 103: judging whether system is in " health status ", if so, entering step 104；If not, entering step
105；
Step 104: system is in " health status ", and the data transmission between publisher and subscriber uses udp protocol；
Step 105: system is in " unhealthy status ", and the data transmission between publisher and subscriber uses Transmission Control Protocol.
Optionally, in a step 102, a threshold value is set in advance, is greater than or equal to this when heartbeat is bundled into the received ratio of function
When threshold value, system is considered as " health status "；When heartbeat is bundled into the received ratio of function less than the threshold value, system is considered as " non-
Health status ".
