To solve the problem of poor load balancing performance and difficult path deployment in the traditional networks

a SRMFT(Segment Routing based Multipath Flow Transmission) mechanism is designed

which utilizes the centralized control advantage of software-defined networking.Firstly

the SRMFT optimization model is set up to achieve the co-optimal scheduling of the data stream.Secondly

the multi-path flow scheduling problem is transformed into the simplest SIDs(Segment IDentify sequence) selection problem with segmented routing algorithm and the simplest SIDs generation algorithm.And the traffic flow scheduling algorithm is proposed.Finally

experimental results show that

under the same network traffic model

compared with the typical multi-path streaming mechanism

SRMFT effectively improves the bisection bandwidth of networks

reduces the transmission delay of short stream

and also have a lower flow table storage overhead.
