Systematic Comparative Study of Circuit Switching, Packet Switching, and Hybrid Switching In Modern Communication Networks
Abstract
The diversity of the traffic in the communication networks underscores the inadequacy of either circuit switching or packet switching. Packet switching is good at statistical multiplexing, and may prove difficult to provide bounded delay and low jitter without excessively provisioning it. Circuit switching on the other hand provides certain delay and bandwidth. In this paper, a literature search and synthesis of circuit switching, packet switching, and hybrid modes is presented based on the principle, current advances, and performance analysis. We discuss such important hybrid paradigms as Asynchronous Transfer Mode (ATM), Multiprotocol Label Switching (MPLS), optical circuit/packet data-center architectures, and 5G-Time-Sensitive Networking (TSN) integration, as well as dynamic circuit allocation algorithms. We find through our synthesis that selective hybrid switching, which dynamically allocates circuit-like resources to URLLC flows or long-lived elephant flows and uses packet switching to serve best-effort traffic, is better in the performance metrics of latency (example, 10 milliseconds of latency in loads where best-effort traffic is provided by the use of a pure paradigm) and throughput, energy consumption, and QoS as the reviewed studies propose. Nanosecond-scale optical circuit switches and programmable data planes have nanosecond optical configurability, enabling historical scalability problems to reduce. Subsequently, hybrid switching creates an effective grid of 6G mobile networks, future data network interconnects, industrial automation, and deterministic
