Abstract
With the rapid emergence of new businesses like the Internet of Things and the Industrial Internet,networks face significant challenges in determinism,security,and resource allocation.Existing networks operate under a"best-effort"model,managing network resources without controlling service or application connections.Network 5.0 addresses these problems by proposing solutions such as innovative protocols,deterministic networks,intrinsic security and trust,self-organizing networks,and computational networks.Besides,Network 5.0 needs to resolve the Over-The-Top(OTT)problem,namely,the insufficiency in controlling and matching applications and network layers for current business support.Thus,this paper analyzes four motivations for Network 5.0 service networks.Subsequently,it presents the service network architecture by overlaying a service core layer onto the existing network transport layer,enabling dynamic service perception,connections,resource matching,and connection control capabilities.This inherently resolves the deterministic support Underlay+Overlay coordination of application.Finally,it highlights two typical scenarios,namely,supercomputing and uninterrupted live broadcasting.These serve as robust indicators for future directions in network research.关键词
