Embodiment
The embodiment of the present invention provides a kind of business data transmission scheme, by determine the SCTP coupling of the transmission rate that can support flow rate test message from will the SCTP coupling of service data transmission, and then utilize the SCTP coupling that can support this transmission rate of determining to transmit this business datum, thereby will cause not supporting the SCTP coupling of this service data transmission rate to be got rid of owing to there is congested or fault, guaranteed that the current SCTP coupling that this business datum is transmitted is all the SCTP coupling that can guarantee the required transmission rate of business datum, avoided making because SCTP coupling is congested business datum to be subject to the problem of transmission restriction.
Particularly, first the embodiment of the present invention provides a kind of service data transmission method, below in conjunction with each accompanying drawing, embodiment of the present invention technical scheme main is realized to principle, embodiment and the beneficial effect that should be able to reach is explained in detail.
As shown in Figure 1, be the specific implementation schematic flow sheet of this service data transmission method of the embodiment of the present invention, the method comprises the following steps:
Step 11, each SCTP SCTP coupling that utilization will be transmitted business datum, transmit default flow rate test message, wherein, in SCTP coupling, transmitting flow rate test message transmission rate used is not less than and in SCTP coupling, transmits this business datum transmission rate used, preferably, can be that in determining each SCTP coupling, to have a SCTP coupling at least be first described business datum to be transmitted, or determine that in each SCTP coupling, having a SCTP coupling at least is after first described business datum being transmitted after recovering from Transmission fault or transmitting congested fault, carry out this step 11,
Step 12, from each SCTP coupling that will transmit business datum, determines the SCTP coupling of the transmission rate that can support this flow rate test message;
Step 13, utilizes definite SCTP coupling to transmit this business datum.
The such scheme being provided from the embodiment of the present invention, because this scheme can be transmitted business datum first in SCTP coupling, or SCTP coupling is from Transmission fault or in transmitting congested fault and first business datum being transmitted after recovering, first determine the SCTP coupling of the transmission rate that can support flow rate test message, the transmission rate adopting while transmitting in SCTP coupling due to flow rate test message is not less than the transmission rate adopting when the business datum that will transmit is transmitted in SCTP coupling, thereby can guarantee that business datum is from the starting stage of transmission, in the SCTP of supporting business message transmission rate coupling, pass elm exactly, therefore the transmission rate of business datum can not be subject to occurring interrupting or the impact of congested SCTP coupling, solved the problem that makes business datum be subject to transmission restriction in prior art because SCTP coupling is congested.
