Our previously proposed business model [6] is a service- oriented hierarchical model in which different levels of services (offered by various players) can be dynamically discovered, used, and composed.
This model promotes the idea of network as a service, by considering the functionalities offered by different types of network resources as services of different levels – services that can be dynamically discovered, used, and composed.
Our platform (dubbed the Open Virtual Playground) promotes the idea of "network as a service" by defining different levels of services to which networking resources are mapped, and which can be dynamically discovered, used, and composed.
However, to the best of our knowledge, these proposals have not yet fully investigated a service-oriented hierarchical architecture, in which different types of functionalities that could be offered by a network resource (e.g., low level routing/transport functionalities, high level application logics) can be dynamically discovered, used and composed.
Resource Publication and Discovery: Once resources are described, their related information is advertised and dynamically discovered by different entities wishing to make use of those resources.
Finally, just like web services, various levels of network services can be published, dynamically discovered, composed, and used, in our model.
Accordingly, in other sensory systems, the GABAergic network has been demonstrated to be dynamically modulated by external inputs [35], [36].
The PHF1 epitope (comprising pSer396 and pSer404) appears to be dynamically regulated by stress.
H3K4 methylation can, however, be dynamically reversed by histone demethylases [ 11, 22].
LOX-1 can be dynamically up-regulated by various proinflammatory, pro-oxidative, and mechanical stimuli [ 14– 16].
