### Others Related Management Projects  
In this subsection, some autonomous management projects are explained. ANA: Autonomic network Architecture  
This is an initiative established by European Foundation, that has some companies and universities as partners such as: ETH Zurich, NEC, University of Oslo, University of Waterloo, University of Basel, University of Lancaster, Fokus, University of Liege, Pierre University et Marie Curie, NKUA and Telecom Austria. It has as aim the development of a goal-architecture for autonomous networks [21]. The main aims of the project are:  
* _Scientific:_ In this aim concern to identify the principles of the autonomous computing, that allows the network could not only be scalable in size but also in functionalities. Therefore, some self-x attributes are desirable as auto-optimization, the self-monitoring, self-repair and self-protection. * _Technological:_ The technological aim concerns in constructing one _framework_ that is able to interconnect different types of networks in an independent way and without direct intervention of the administrator of the network. The self-organization concept is developed considering each node individually inside the network. The architecture allows the dynamic adaptation and reorganization of traffic according to the user's necessity. Besides the dynamic adaptation, the architecture still supports mobile nodes and multiple administrative domains. The architecture of each node and the architecture of the network. In the architecture of each individual node the application layer can be perceived, that provide services as www, email, ftp, DNS, to peer-to-peer (kazaa, emule) voip (Skype), among other supported application. The concept of compartment is also introduced in the architecture of a node. The concept of compartment is implemented according to operational rules and administrative politics for a given communication context. In which it defines as a node enters and leaves the network, who are the registered members, the authentication model and how the node is communicated with another member of the network (routing, communication _to peer-to-peer_, addressing). The compartment concept configures the system of communication in small units of management; this enables the network to have a local vision of each node, in order to provide a self-organization at global level. The process of self-association and organization has the function to associate the new fixed nodes or not, that want to enter in the network. This process has one high level of abstraction for the user. The architecture of the network has the property of discovering services or resources, in which they abstract a list of services that each node can provide; an example would be a node with bigger capacity of storage and another one with capacity for printing. CASCADAS:Component ware for Autonomic, Situation-aware Communications and Dynamically Adaptable Service  
This project was initiated in January 2006 and founded by _European Commission_, aiming development of architecture for self-organization and communication services. The CASCADAS project uses the model of _Autonomic Communication Element_ - ACE. An ACE acts as entity, that can implement a distributed way of communication and services and also act as a central point of services [22]. In this case a ACE model must integrate all the self-organized capacities and must be the basis for the implementation of the situated services of communication in the application layer, as well as the basis of implementation for the network layer and the level layer of _middleware_. In Cascades project the application layer, distinguishes the dynamic development of components, with the coupling of components for autonomous applications. In the layer of _middleware_ or _middle_ we can see some capacities as self-cure (self-healing), pervasive supervision and knowledge of the network, that are dynamically aggregate functions according to the autonomous behavior of the network.
