| 69 | based on the proposed Common API (CAPI) for structured Peer-to-Peer |

| 176 | <span lang="EN-GB"><font size="2">The main conceptual entity and |
|---|
| 177 | obvious hotspot of this layer is the Node. A node contains |
|---|
| 178 | incoming and outgoing message queues and methods for sending and |
|---|
| 179 | receiving/ processing messages. Each particular node must then |
|---|
| 180 | include a complete behaviour or protocol that will dictate which |
|---|
| 181 | messages to send in specific times and how to react to incoming |
|---|
| 182 | messages. Furthermore, to create a new overlay, the embedded protocol must define its own |
|---|
| 183 | messages with specific information to arrange the overlay. This |
|---|
| 184 | also implies that developers should be able to define their own |
|---|
| 185 | message types (hotspot).</font></span></p> |

| 189 | <span lang="EN-GB"><font size="2">At the overlay layer, the |
|---|
| 190 | communication is bidirectional with both the application and |
|---|
| 191 | network layers. With the application layer, the Node notifies |
|---|
| 192 | the Application of received messages (upcalls) and it is invoked |
|---|
| 193 | by the EndPoint façade in order to route messages or obtain |
|---|
| 194 | routing state information (downcalls). Both the EndPoints and the |
|---|
| 195 | Nodes exchange RouteMessage types. A RouteMessage contains |
|---|
| 196 | source and target identifiers, as well as information regarding |
|---|
| 197 | the next hop in the overlay. It is also possible to modify the |
|---|
| 198 | next hop route at the application or overlay layers in order to |

|---|
| 206 | life’s cycle of every node. The method <i>process </i>contains |
|---|
| 207 | the specific protocol each node maintains to create the overlay. |
|---|
| 208 | Besides, every node has an incoming and an outgoing message |
|---|
| 209 | queue; incoming messages are parsed every step in the <i>process |

| 214 | <span lang="EN-GB"><font size="2">To identify nodes in the |
|---|
| 215 | overlay, the simulator employs three main entities: Id, |
|---|
| 216 | IdFactory and NodeHandle. Ids are custom number types of 32 to |
|---|
| 217 | 160 bits that identify nodes in the overall key based routing |
|---|
| 218 | scheme. The extensible IdFactory permits to define custom Id |
|---|
| 219 | generation schemes in each overlay. Additionally, NodeHandles |
|---|
| 220 | contain IP to Id value pairs for each node. Furthermore, a |
|---|
| 221 | NodeHandle provides a <i>proximity </i>method that queries the |
