|---|
| 93 | framework for overlay networks and services. This framework presents |
|---|
| 94 | a layered and modular architecture with well defined hotspots |
|---|
| 95 | documented using classical design patterns. In PlanetSim, developers |
|---|
| 96 | can work at two main levels: creating and testing new overlay |
|---|
| 97 | algorithms like Chord or Pastry, or creating and testing new |
|---|
| 98 | services (DHT, CAST, DOLR, etc) on top of existing overlays. </font> </span> |
|---|

|---|
| 100 | <p style="text-align: justify; text-autospace: none"> |
|---|
| 101 | <span lang="EN-GB"><font size="2">PlanetSim also aims to enable a smooth transition |
|---|
| 102 | from simulation code to experimentation code running in the |
|---|
| 103 | Internet. Because of this, we provide wrapper code that takes care |
|---|
| 104 | of network communication and permits us to run the same code in |
|---|
| 105 | network testbeds such as PlanetLab. Moreover, distributed services |
|---|
| 106 | in the simulator use the Common API for Structured Overlays. This |
|---|
| 107 | enables complete transparency to services running either against the |
|---|
| 108 | simulator or the network.</font></span></p> |
|---|
| 109 | <p style="text-align: justify; text-autospace: none"> |
|---|
| 110 | <span lang="EN-GB"><font size="2">PlanetSim has been developed in the Java language |
|---|
| 111 | to reduce complexity and smooth the learning curve in our framework. |
|---|
| 112 | We however have profiled and optimised the code to enable scalable |
|---|
| 113 | simulations in reasonable time. To validate the utility of our |
|---|
| 114 | approach, we have implemented two overlays (Chord and Symphony) and |
|---|
| 115 | a variety of services like CAST, DHT, and object middleware. We have |
|---|
| 116 | proved that PlanetSim reproduces the measures of these environments |
|---|
| 117 | and is also efficient in its network implementation.</font></span></p> |

|---|
| 122 | <p style="text-align: justify"><span lang="EN-GB"><font size="2">PlanetSim’s architecture comprises |
|---|
| 123 | three main extension layers constructed one atop another. Applications |
|---|
| 124 | are built in the upper layer using the standard Common API façade. This |
|---|
| 125 | façade is built on the routing services offered by the underlying |
|---|
| 126 | overlay layer. Besides, the overlay layer obtains proximity information |
|---|
| 127 | to other nodes asking information to the Network layer. |
