With the integration of big data in the Software Defined Network（SDN）network applications

a series of Quality of Equipment（QoE）problems are emerging gradually

such as data flow failure which is caused by failure to update the flow table in real time.In order to solve this issue

this paper proposes an algorithm based on stagnation timeout optimization to enhance the availability of OpenFlow switch table resource in a burst load environment.The algorithm can make the data stream and the flow item match smoothly

and then improve the efficiency of data stream forwarding through dynamic balance table flow resource

control resources

and reasonable setting timeout.At the same time

the algorithm seals the flow table entries that are successfully matched with the data flow in the stream table

and effectively improve the survivability of the flow table in time.Experimental results show that the stopping timeout improvement mechanism in the algorithm is more effective than the fixed timeout mechanism in terms of QoE.
