## 1 Introduction
CONVERGENCE is compatible with IP by using IP option extension to deliver the CONVERGENCE packet. DONA [9] employs a self-verified flat name and the Resolution Handlers (RHs) maintain all of the information of the names. In DONA, every Autonomous System (AS) has more than one logical RH, which are connected to each other to form a hierarchical NRS. In PURSUIT [12], the REndezvous NETwork (RENE), which is made up of a collection of Rendezvous Nodes (RNs), plays the role of name resolution and constitutes the global NRS. Each AS can have its own RENE and the RENE onthe top of each AS acts as the global RENE for global name resolution. In SAIL [17], there exist local NRS and global NRS. Users first query the local NRS, and if there is no requested content, then the resolution message isforwarded to the global NRS. In the decoupled model of COMET [13], the Content Resolution System (CRS) plays the role of name resolution. In MF [18], each information object in MF has a flat name Global Unique Identifier (GUID), and GUID is translated into NA(s) via a Global Name Resolution Service (GNRS). In this paper, we focus on the name resolution service when integrating ICN into 5G networks. The key functionalities of ICN architectures are naming, name resolution, data routing, mobility, caching, and security [19], and the name resolution is the heart of ICN. The requirements of ICN NRS are divided into three aspects, including delay sensitivity, accuracy, and resolution guarantee [21]. [PERSON] et al. classified the requirements of ICN NRS as: (i) content locality, (ii) local resolution and forwarding locality, (iii) simplified deployment to support efficient name resolution [22]. Though many ICN name resolution approaches have been proposed, there are still some limitations on adapting them to fulfill the requirements of 5G networks. On the one hand, the latency of name resolution cannot be guaranteed. Service types, including content distribution, video conferencing, and Machine-to-Machine (M2M) applications, are sensitive to latency, while Distributed Hash Table (DHT)-based name resolution approaches are overlay designs. The routing path may be mismatched with the underlay routing path, resulting in long latency. On the other hand, on-demand name registration and resolution are lacking to fulfill differentiated requirements for heterogeneous environments and applications. The content and data produced by the Internet are exploding. The number of mobile devices has reached 3 billion, and more than 5 billion new videos are generated every day, and in the near future, there will be more than 100 billion IoT devices. In ICN, the magnitude of information objects can reach \(10^{13}\) and can be furtherly increased to \(10^{15}\)[22]. How to obtain NDO through location-independent names and how to support tera-scale name storage and name resolution are some of the most important challenges in ICN network architecture design. The name information in the NRS should be placed as close as possible to the users, and the NRS should be able to route the data request to the nearest copy to reduce response latency. Therefore, it is urgent to realize local resolution and forwarding locality to minimize the inter-domain traffic and reduce the lookup latency. In addition, the trend of the future network is transferred from best-effort to deterministic data transmission. Deterministic transmission under harsh conditions is in great demand for the application services in industrial environments and in vehicle networking, etc. Nowadays, as Time-Sensitive Network (TSN) have been embodied, there are many existing solutions for the physical and Media Access Control (MAC) layers, however, there still need more innovative research efforts to realize overall deterministic end-to-end transmission upon whole internet protocol stacks. As name resolution is at the heart of ICN, to meet the delay-sensitive requirement of NRS in a 5G-ICN network, we try to introduce the concept of Deterministic Latency into NRS on the network layer.
