PriQoS:priority-differentiated flow control mechanism based on SDN by Zhi SUN, Ming CHEN

“…It was difficult to meet the increasing demand of quality of service (QoS) for the best-effort IP network,so it was urgent to develop a kind of QoS control mechanism that was compatible with the existing IP software and hardware resources.Therefore,a priority-differentiated control mechanism based on the software defined networking called PriQoS was proposed.When the network resource was scarce,a multi-queue bandwidth allocation algorithm based on the inte-grated priority of service flow was used to meet the bandwidth requirement with high priority flows.PriQoS was deployed on the network edge,which was no need to modify applications in the end systems and routers in the core network.The mechanism has advantages such as easy to deploy and being compatible with the IP applications and devices.Experimental results show that the PriQoS mechanism can guarantee the QoS of higher priority services.…”

Symbolic execution optimization method based on input constraint by Sunlyu WANG, Yuqi LIN, Qiusong YANG, Mingshu LI

“…To solve path explosion,low rate of new path’s finding in the software testing,a new vulnerability discovering architecture based on input constraint symbolic execution (ICBSE) was proposed.ICBSE analyzed program source code to extract three types of constraints automatically.ICBSE then used these input constraints to guide symbolic execution to focus on core functions.Through implemented this architecture in KLEE,and evaluated it on seven programs from five GNU software suites,such as coreutils,binutils,grep,patch and diff.ICBSE detected seven previously unknown bugs (KLEE found three of the seven).In addition,ICBSE increases instruction line coverage/branch coverage by about 20%,and decreases time for finding bugs by about 15%.…”
