摘要： Systems and methods for data scheduling and queuing. A data network node is configured to transmit data in a store-and-forward fashion. The data network node includes a delay and validity determination module that determines and assigns a validity value to each data packet incoming via an input port based on a time stamp of the data packet, a current time value, an expected delay on a route of the data packet to its destination, and a packet urgency value. A scheduling module and a queue managing module execute their functions based on the validity value assigned to a data packet in a transmission buffer.
