The invention relates to a combined utilization system and method for bus transit lane remaining traffic capacity. The system mainly comprises a changeable information screen, a traffic detector and a video monitoring and controlling center and automatically detects the bus transit lane remaining traffic capacity. When the remaining traffic capacity reaches a set opening threshold value of the system, the system will issue information of allowing qualified vehicles to enter through the dynamic information screen above a bus transit lane, and when the remaining traffic capacity reaches a set closing threshold value of the system, the system will prohibit non-bus vehicles from entering the bus transit lane. Only the vehicles meeting related conditions are qualified to enter the bus transit lane. The remaining traffic capacity of the bus transit lane can be detected in real time, the defect that the bus transit lane and adjacent lane resource utilization is not balanced is overcome, and through limiting the qualification of the vehicles which can be allowed to enter the bus transit lane, the driving order environment is optimized, and the vehicles are guided to go in and out in order in a civilized mode.

The invention discloses a fine-grained network traffic scheduling method and system under network function virtualization and belongs to the field of network function virtualization. The scheduling method is a distributed method. Each network node can carry out network traffic scheduling after each network node acquires partial network state information. Specifically, according to the method, different control policies are carried out at each moment according to current states of each network node and links, and data packet queue information of different network traffic. The control policies comprise an access control policy, a processing control policy and a transmission control policy. The data packet queue information is updated according to results of the policies. The scheduling system is responsible for maintaining queues, collecting network state information and acquiring a scheduling result through utilization of the scheduling method according to the information. Network functions are used for performing specific tasks according to the scheduling result. According to the scheduling method and the system, the network traffic is dynamically scheduled according to the currentnetwork states, a whole network system is guaranteed to be in a stable state, and the total average throughput is optimized.
