Method for deployment of communication networks includes obtaining entity attribute data corresponding to a plurality of network entities associated with a communication network. The plurality of network entities may include physical entities, logical entities, and service entities. Further, the method includes defining association between at least one network entity and at least one other network entity based on one or more pre-defined association rules and the entity attribute data. The method also includes generating a network model, based on the defined association between the at least one network entity and the at least one other network entity, for deployment of the communication network. The network model represents association between the at least one network entity and the at least one other network entity.
