在边缘计算部署中，设备可能彼此非常接近，这些设备可能卸载类似的计算任务（即，具有相同边缘计算服务或相同性质的服务的类似输入数据的任务）。这导致重复（冗余）计算的执行，这可能成为未来边缘计算环境的一个紧迫问题，因为这种部署被设想为由边缘的小规模数据中心组成。为了解决这个问题，在本文中，我们强调了范式对于网络边缘计算的重复数据删除和重用的重要性。这样的范例有可能显著减少卸载任务的完成时间，在部署相同数量的边缘计算资源的情况下容纳更多的用户、设备和任务；然而，它们也有自己的技术挑战。最后，我们提出了一种多层架构，以实现网络边缘的计算重复数据删除和重用，并讨论了开放的挑战和未来的研究方向。
In edge computing deployments, where devices may be in close proximity to each other, these devices may offload similar computational tasks (i.e., tasks with similar input data for the same edge computing service or for services of the same nature). This results in the execution of duplicate (redundant) computation, which may become a pressing issue for future edge computing environments, since such deployments are envisioned to consist of small-scale data centers at the edge. To tackle this issue, in this article, we highlight the importance of paradigms for the deduplication and reuse of computation at the network edge. Such paradigms have the potential to significantly reduce the completion times for offloaded tasks, accommodating more users, devices, and tasks with the same volume of deployed edge computing resources; however, they come with their own technical challenges. Finally, we present a multi-layer architecture to enable computation deduplication and reuse at the network edge, and discuss open challenges and future research directions.
