Recently, there is an increasing demand for ultra-low-latency (ULL) services such as factory automation, autonomous driving, and telesurgery that must meet end-to-end latency of less than 10 ms. Fifth-generation (5G) New Radio guarantees 0.5 ms one-way latency, so the feasibility ULL higher in previous mobile communications. However, this ensures performance at radio access network level requires innovative 5G architecture across entire system. Hence, we survey detailed two 3rd Generation...
The fourth industrial revolution is accelerating automation. In networks, manufacturing processes require hard real-time communication where the latency less than 1ms. Time-sensitive networking (TSN) technology over Ethernet already supports deterministic delivery for communication. However, TSN technologies wireless networks are currently in their initial development stage. Therefore, this study presents an overview of research trends communications. This paper focuses on 5G and IEEE...
Abstract We propose a bandwidth prediction approach based on deep learning. The is intended to accurately predict the of various types mobile networks. first use machine learning technique, namely, gradient boosting algorithm, recognize connected network. Second, we apply handover detection algorithm network recognition account for vertical that causes variance. Third, as communication performance offered by 3G, 4G, and 5G networks varies, suggest bidirectional long short‐term memory model...
A seamless handover scheme with low latency and packet loss is important to maintain TCP performance of mobile users. Several solutions have been proposed such as Hierarchical Mobile IPv6 (HMIPv6), Fast Handover protocol for (FMIPv6), Seamless Handoff architecture IP (S-MIP), ..., however, the overall still too high time-sensitive services. This paper proposes a novel improvement existing frameworks by optimizing address configuration stage so that further reduced. The framework based on...
Multiprotocol label switching (MPLS) is a method of IP packets through network by applying simple labels to packets. It provides the privacy and quality service (QoS) advantages connection-oriented services. Other benefits MPLS include traffic engineering capabilities needed for efficient use resources. Traffic shifts load from overutilized portions underutilized portions, according destination, type, load, time day, so on. As VPN market grows, QoS offerings required provide groups premium...
Various technologies have been developed for the efficient use of multiple radio access resource at network level or other levels to improve user service quality in mobile communication networks. In long-term evolution, carriers are commercializing network-level traffic aggregation such as licensed-assisted access-long-term evolution-unlicensed, and evolution-wireless local area aggregation, which multi-accesses 3rd Generation Partnership Project WiFi, multipath transmission control...
Anycast service provides load-balancing since giving a user connection to the nearest server, and also improves server's bandwidth quality of service. It maintains continuity in failure prevents damages from instability, DoS attacks against etc. As kinds become various gradually Internet environment, demand for anycast has been increased due these advantages. However is staeless service, it suitable application using UDP protocol. The unable guarantee that multiple datagram are delivered...
The 3rd Generation Partnership Project (3GPP), which has developed the most successful standard technologies in mobile communication market, is currently carrying out 5G standardization of both access network (AN) and core (CN) system. (5GC) was designed to be commonly connected multiple networks first phase (Release 15) normative standardization. In next 16), Access Traffic Steering, Switching Splitting (ATSSS), one work items converge 5GC, under this paper, we propose an efficient session...
Mobile carriers run IP services like DDoS protection, NAT, and firewalls on their own over the N6-LAN interface. For 5G system (5GS), 3GPP Rel-18 specified service function chaining (SFC) requirements in order to steer traffic through N6-LAN. Developing standards for SFC interface is now early stages. In provide service, this paper proposes 5GS. We also examine that our proposal complies with requirements.
The Internet Protocol (IP) has been the foundation of Internet. As grown, IPv4 was inadequate to meet performance and functional requirements for In response these needs, Engineering Task Force (IETF) issued a new protocol, known as IP version 6 (IPv6) (S. Deering R. Hidned, Dec. 1998), which defined ultimately replace IP. Using dual stack mechanism, router is equipped with double set protocol (IPv4 IPv6). can send receive datagrams belonging IPv4/IPv6 it also forward packets node in IPv6...
Different types of 5G service scenarios impact on network architecture by considering multi-RATs such as RATs, WiFi, and fixed to fulfill the requirements different services. Therefore, new signaling between Consumer Electronics (CE) Core Network (CN) in needs be designed for optimizing coordination access networks. We propose design CE CN through multiple networks support various services beyond.
