  • Publication number: 20200344154
    Abstract: A method for path optimization comprises: obtaining, at an edge node of a network including a plurality of nodes, locations and performances of one or more nodes from among the plurality of nodes in the network; determining performance indices associated with the one or more nodes based on the locations and the performances of the one or more nodes and a service level objective (SLO), a performance index indicating a difference between a performance of a respective node and the SLO; and determining, based on the locations of the one or more nodes and the performance indices, a target path for delivering a packet from the edge node to a destination node. Advantageously, the path for transmitting the packet flow is optimized in real time according to dynamic changes in the network environment, so that an end-to-end service level objective is met as much as possible.

  • Patent number: 10783018
    Abstract: Techniques for optimizing a remote call are provided. For example, a method includes obtaining a command for calling a remote dedicated processing resource and determining whether the command satisfies an optimization condition based on a type of the command. The method further comprises in response to determining that the command satisfies the optimization condition, ceasing to transmit the command to the remote dedicated processing resource. Accordingly, in the case that the remote dedicated processing resource needs to be called, the number of remote call commands transmitted to the remote dedicated processing resource can be reduced by optimizing the remote call commands, thereby improving the execution efficiency effectively.

  • Patent number: 10783774
    Abstract: A method for estimating road travel time based on the built environment and low-frequency floating car data belongs to the technical field of urban traffic management and traffic system evaluation. The method takes built environment as an explanatory variable of the road travel time. The interpretability of this variable is proved by a numerical example. In addition, the method determines distribution parameters of road travel time using the number distribution of vehicles instead of distance. The benefits of the method are that: (1) it explains the positive effect of built environment on road travel time; and (2) it reflects the speed difference among different road sections, which can improve the precision of estimating road travel time.

  • Patent number: 10748421
    Abstract: The present invention relates to a method for estimating distribution of urban road travel time in considering operation state of taxi, and belongs to the technical field of urban transportation planning and management. The distributions of path travel time are respectively estimated according to different operation states of the taxi. When the distribution of the path travel time is estimated, adjacent road sections in the road network are not independent. In the present invention, the Markov model is added to describe the correlation of the travel time distribution between the adjacent road sections, so as to increase science and accuracy of the estimation result. In the present invention, the weight is set according to the proportion of the number of the vehicles under two different operation states to obtain the final distribution of the path travel time.
