The development of a 5G-enabled Internet of Things has led to a dramatic increase in network traffic load, which has presented tremendous challenges to network management. In this paper, a service-oriented network architecture is proposed to support the effective management of 5G-enabled IoT systems. This architecture effectively reduces the traffic load and simplifies network management by introducing a service aggregation and caching (SAaC) scheme. Specifically, SAaC first breaks through the data-centric network architecture by converting data into services. Then, SAaC significantly reduces traffic load and energy consumption by service aggregation. Finally, SAaC introduces service caching, and each content router caches new services locally after aggregating received services so that user requests are handled at the network layer. Experimental results demonstrate that compared with traditional solutions, the SAaC scheme improves the request response time by 20.52%-56.09%, reduces the traffic load by 10.85%-37.67%, and reduces energy consumption by more than 50%.

支持5G的物联网的发展导致网络流量负载急剧增加，这对网络管理提出了巨大挑战。本文提出了一种面向服务的网络架构，以支持对启用5G的IoT系统的有效管理。通过引入服务聚合和缓存（SAaC）方案，该体系结构有效地减少了流量负载并简化了网络管理。具体来说，SAaC首先通过将数据转换为服务来突破以数据为中心的网络体系结构。然后，SAaC通过服务聚合显着减少流量负载和能耗。最后，SAaC引入了服务缓存，并且每个内容路由器在汇总接收到的服务后在本地缓存新服务，以便在网络层处理用户请求。
