Edge computing local breakout
The present disclosure describes local breakout for edge computing systems, wherein the local breakout selectively routes the traffic from/to a user equipment between an edge compute node or some other service such as a core network, cloud computing service, or the like. Packets related to microservices that are offered by the edge compute node are routed to the edge compute node instead of routing those packets to the core network, and packets that are not related to the microservices provided by the edge compute node are routed to the core network or to another network such as a data network or cloud computing service. In these ways, the local breakout mechanisms provide low latency and reduced network resource consumption for the microservices and decreased data traffic load on the core network. |

Computing device and method for tracking movement of objects
A computing device, method and computer program product track the movement of objects and identify potential collisions between object influence models of two or more objects. In a method, an object influence model is defined for a respective object with the object influence model having a shape and volume that encompasses the respective object. The object influence model extends beyond the respective object and varies in response to changes in one or more properties of the object. The method also includes receiving information from one or more sensors indicative of movement of the respective object and predicting its anticipated path of travel. The method further includes identifying a potential collision between the respective object and another object in an instance in which the object influence models of the respective object and another object intersect as the respective object is advanced along the anticipated path of travel. |
