This article proposes a network control method that realizes on-demand service providing in Elastic Lambda Aggregation Network (EλAN). EλAN is a next-generation access/aggregation network that provides various network services having different protocols and QoS requirements. EλAN also achieves the reduction of total network power consumption by sharing access network equipment by multiple network services. In the proposed method, fixed optical trees are introduced to EλAN to exchange control messages in the same manner as today's FTTH systems. Discovery process and optical path/tree aggregation using the optical trees are explained in this article. We also discuss the energy-saving effect of the optical path/tree aggregation in EλAN.
