Network function virtualization (NFV) and software defined networking (SDN) have been widely recognized as the main direction of the development of the next generation telecom network
and as the brain of the future network
orchestrator is the key for the operators to manage the network flexibly and maximize the advantages of new technologies.Firstly
the core position of orchestrator in the next generation network was described
and the technical architecture of orchestrator was introduced.Then
the development of orchestrator in the perspective of standardization and open source were introduced and analyzed.Finally
the relationship between standardization and open source was elaborated
including the integration of orchestrator and OSS
the support of orchestrator for SDN and the idea to realize the intelligent and automatic network operation relying on orchestrator.
