The Internet of Things (IoT) is one of the main enablers for situation awareness needed in accomplishing smart
cities. IoT devices, especially for monitoring purposes, have stringent timing requirements which may not be
met by cloud computing. This deficiency of cloud computing can be overcome by fog computing for which fog
nodes are placed close to IoT devices. Because of low capabilities of fog nodes compared to cloud data centers,
fog nodes may not be deployed with all the services required by IoT devices. Thus, in this article, we focus on
the issue of fog service placement and present the recent research trends in this issue. Most of the literature on
fog service placement deals with determining an appropriate fog node satisfying the various requirements like
delay from the perspective of one or more service requests. In this article, we aim to effectively place fog services
in accordance with the pre-obtained service demands, which may have been collected during the prior time
interval, instead of on-demand service placement for one or more service requests. The concept of the logical
fog network is newly presented for the sake of the scalability of fog service placement in a large-scale smart city.
The logical fog network is formed in a tree topology rooted at the cloud data center. Based on the logical fog
network, a service placement approach is proposed so that services can be placed on fog nodes in a resourceeffective
way.

Due to the convergence of voice, data, and video, today’s telecom operators are facing the complexity of service and network management to offer differentiated value-added services that meet customer expectations. Without the operations support of well-developed Business Support System/Operations Support System (BSS/OSS), it is difficult to timely and effectively provide competitive services upon customer request. In this paper, a suite of NGOSS-based Telecom OSS (TOSS) is developed for the support of fulfillment and assurance operations of telecom services and IT services. Four OSS groups, TOSS-P (intelligent service provisioning), TOSS-N (integrated large-scale network management), TOSS-T (trouble handling and resolution), and TOSS-Q (end-to-end service quality management), are organized and integrated following the standard telecom operation processes (i.e., eTOM). We use IPTV and IP-VPN operation scenarios to show how these OSS groups co-work to support daily business operations with the benefits of cost reduction and revenue acceleration.
