在本文中,我们研究了一个年龄的信息最小化问题,多个流的更新数据包发送到多个服务器到他们的目的地。提出了两种在线调度策略。当数据包的生成和到达时间是同步的流,所提出的政策被证明是(近)最优的最小化任何时间依赖的,对称的,和非递减的惩罚函数的年龄的流随着时间的推移在随机排序的意义。
In this paper, we study an age of information minimization problem, where multiple flows of update packets are sent over multiple servers to their destinations. Two online scheduling policies are proposed. When the packet generation and arrival times are synchronized across the flows, the proposed policies are shown to be (near) optimal for minimizing any time-dependent, symmetric, and non-decreasing penalty function of the ages of the flows over time in a stochastic ordering sense.
