Abstract

Abstract:

Different network techniques are developing autonomously within their own region, besides, various new network techniques come out increasingly.However, the different network techniques cannot coordinate with each other to support the various business efficiently.Based on polymorphic networks and business environments, the researches about the coordinated scheduling of networks and businesses were illustrated from the perspective of the operator’s management and operation.The intent-based cooperative architecture of polymorphic network and service was proposed, which was driven by polymorphic business services.Furthermore, the way to orchestrate the network capabilities intelligently, and to promote the business innovation were explicated.

Key words: polymorphic network, service orchestration, intent-based network, intelligent operation
