边缘计算使应用服务能够利用低延迟响应，例如，for augmented增强reality现实.用于边缘计算的网络结构即服务（EC-IaaS）允许多个应用服务提供商（ASP）使用虚拟化资源（即，虚拟机（VM）和虚拟网络），用于公共边缘计算基础设施上的各种应用服务。对于ASP，VM与终端用户设备的接近度（即，主机边缘服务器的位置）是保证低延迟响应时间的重要因素。现有方法允许ASP选择边缘服务器位置，以便VM满足邻近度要求。然而，从EC-IaaS提供商传输到ASP的信息量变得很大，因为它必须包括所有边缘服务器位置和所有无线基站之间的延迟。我们提出了一种方法，减少了信息量，同时确保ASP获得满足邻近要求的虚拟机。EC-IaaS提供商建议在适当的邻近范围内具有VM的无线基站组，这有助于ASP估计所需的VM数量。EC-IaaS提供商决定哪些边缘服务器应该包含VM，而不是ASP。我们确认，所提出的方法减少了传输的信息。EC-IaaS提供商还有一个好处，即与现有方法相比，详细的延迟信息对ASP保持封闭，并且功耗持续。
Edge computing enables application services to leverage low-latency responses, e.g., for augmented reality. Infrastructure-as-a-service for edge computing (EC-IaaS) allows multiple application service providers (ASPs) to use a virtualized resource (i.e., virtual machines (VMs) and virtual networks) for various applications services on the common edge computing infrastructure. For ASPs, the proximity of the VMs to the end-user devices (i.e., the location of the host edge servers) is a significant factor in guaranteeing low-latency response times. The existing method allows ASPs to select the edge server locations so that the VMs satisfy the proximity requirement. However, the amount of information transmitted from the EC-IaaS provider to the ASP becomes large, because it has to include the latencies between all edge server locations and all wireless base stations. We propose a method that reduces the amount of information while ensuring that ASPs obtain VMs that satisfy the proximity requirement. An EC-IaaS provider suggests groups of wireless base stations that have VMs within a suitable proximity, which helps the ASPs to estimate the necessary number of VMs. Instead of the ASP, the EC-IaaS provider determines which edge servers should contain the VMs. We confirm that the proposed method reduces the transmitted information. The EC-IaaS provider also has a benefit that detail latency information is kept closed to ASPs and the power draw is sustained compared to the existing method.
