“…The protocol messages and sizes of LISP, IP mobility, and OpenFlow used in this analysis are listed in Table II. The mathematical model and all values for calculating the operational cost were referenced from [29] and for calculating handover delay were referenced from [30]. However, as the references did not consider the SFC environment, this study additionally assumed that a service chain including the , i.e., number of services, in the ℎ − , i.e., number of xTRs in the endto-end path, was configured.…”

“…In [29], the total operating cost for the mobile terminal in the LISP-based environment is defined as the sum of the location update cost , map discovery cost , and packet delivery cost . However, in this analysis, it is difficult to accurately compare other costs because the packet delivery cost may be significantly larger than other costs with the increase in the service chain path.…”

Service function chaining, which provides a sequential set of multiple services in an end-toend communication path, is a key technology for providing better service quality to users and efficient management of the network. Recently, as the services traditionally deployed in the data center have become more proximate to the user using a distributed cloud environment, the management of the service chain has become more complex for connecting services between clouds at a distance. In particular, when a user moves and resumes end-to-end communication at a new location, these complexities may lead to an increase in service downtime, which results in network performance degradation. In this paper, we propose an integrated control system to quickly recover the path to the service chain along with mobility management. The proposed system is based on the locator/identifier separation protocol to provide cost-effective mobility management by integrating the location information of users and services into the service chain mapping system. Based on the analysis of the operating cost and handover delay, it was determined that the proposed system can quickly restore a service chain path between distributed clouds with less signaling exchange and minimum delay when compared to previous approaches.

“…In the mobile-to-mobile scenario analysis, the end-to-end path was calculated as approximately double that of h_(S-opt) and h_(S-nonopt). The number of hops for each route is assumed, as shown in Table 1 [26]. Based on the reference architecture, we compared the operational costs of our proposal with LISP-MN [25], LISP-FMC [12], and LISP-PACAO [13].…”

“…Because other approaches consider only the service migration scenario, but not the scenario with equivalent services running in a distributed manner, we consider only the operational cost related to the LISP mapping system for the network configuration, and not the costs related to the service migration or optimal service selection process. The mathematical model and all values for calculating the operational cost are referenced from [26]. For the evaluation of SDN-MM, we assume that the Edge Switch (ES) is in position the same as xTR, and SDN Controller as LISP-MS. where denotes the average velocity of the MN and denotes the radius of the circular area of a LISP site.…”

In the evolution of mobile networks, edge computing is a key technology, which provides services with proximity to users and enables various services to be operated in a virtualized platform for mobile users. Particularly, services commonly used by multiple mobile users can be simultaneously operated at multiple edge nodes, which allows users to use the service of the closest node to their access point. However, to provide session continuity for a service when the user moves, a method for optimizing the service path along with the mobility management of the user is required. In this paper, we propose an enhanced control system using the locator/identifier separation protocol to provide service path optimization with mobility management. This was achieved by integrating the location information of the service and the session information between the service and the users. The operating cost and handoff latency were analyzed. The analysis results show that the proposed system can provide an optimal service path to mobile users through fewer message exchanges and less delay than existing approaches.
