VPP-based Hybrid Connectivity Technology to Support Large-scale Metaverse Services

There are some major difficulties to provide large-scale metaverse services in current metaverse environments. The server structure using the TCP protocol and the sequential network processing approach are those. While servers using the TCP protocol offer reliability, their packet processing speed is slow and not well-suited for large-scale metaverse environments. They also face limitations in scaling the server infrastructure. Furthermore, even if server architecture is improved, packets are processed sequentially in traditional networking system, leading to bottlenecks in large-scale metaverse environments where hundreds of transmissions of packets occur simultaneously. In this paper, we aim to address these issues by proposing a hybrid connection technology that combines TCP and UDP supported by parallel packet processing using VPP(Vector Packet Processing), suitable for large-scale metaverse server architecture. Our study results showed that the maximum acceptable number of clients reached was 225, which is more than double the capacity of the existing system, allowing metaverse services to be provided to a larger number of users.
