1 Simulation tools
1.1 DRMSim, a network simulator for the investigation of routing schemes
| Description | The objective of DRMSim is to provide a routing model simulator to the scientific networking community. DRMSim does not aim at performing accurate simulations at the forwarding level. Instead it focuses on the underlying routing layer itself, by exposing a clear and dedicated Application Programming Interface (API) to its users. In other words, it is devoted to the construction of routing tables and so to the evaluation of the behavior and performances of various distributed routing schemes (performance metrics are: stretch, size of routing tables, number of messages, adaptivity to topological modifications, etc.). Simulations are modeled according to the discrete-event paradigm. |

It is an ad-hoc Java simulator that currently implements four schemes only, namely the Shortest Path, Steiner Tree, AMR and PPC algorithms. It Simulations are modeled according to the discrete-event paradigm. |

1.3 FIGHT, Future Internet Graph Hyperbolic Tool
| Description | The FIGHT-software is a generic platform for hyperbolic routing. We built on the one hand a routing-algorithm-interface, that allows calculations for the routing-table information, and on the other hand a forwarder-interface, that allows forwarding-strategies on the basis of the routing-table information. Now, we made a few implementations of these interfaces: for example a random forwarder, and an oracle-forwarder, which automagically takes the good decisions and always forwards to the neighbour that is actually on the shortest path to the destination. Any protocol can be added as desired. The system allows to attach coordinates to nodes, whatever coordinates may be. So this is also an interface that allows the most diverse implementations of actual coordinates, eg. vector-coordinates in a multidimensional hyperbolic space. An algorithm called "the assigner" then assigns coordinates to nodes. On the basis of these coordinates, several strategies to build routing-tables and forwarding algorithms are possible. Thirdly, the system allows to inspect the state of the network, and allow monitoring the performance, whatever that means (e.g. the stretch). We implemented a few coordinate-assignment-strategies and routing-protocols, which we tested under different circumstances (e.g. failing links or nodes). The tool allows to experiment with alternatives in order to derive interesting conclusions about these protocols. |

2 Emulation tools
2.1 Click Modular Router, w software architecture for building extendible and con gurable routers and switches
| Description | Click is a new software architecture for building extendible and configurable routers. A Click router is assembled from packet processing modules called elements. Individual elements implement simple router functions like packet classification, queueing, scheduling, and interfacing with network devices. A router configuration is a directed graph with elements at the vertices; packets flow along the edges of the graph. Several features make individual elements more powerful and complex configurations easier to write, including pull connections, which model packet flow driven by transmitting hardware devices, and flow-based router context, which helps an element locate other interesting elements. |

2.2 Quagga, a routing software suite
| Description | Quagga is an already developed free software routing suite, providing implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPng and BGP-4 for Unix platforms. It is developed in C code and the tools provided by the suite will be used for the real development of the protocols and algorithms (such as compact multicast) defined within the framework of the EULER project. Moreover, the resulting implementations will be able to be tested in real scenarios.. |

3 Measurement tools
3.1 TraceTree
| Description | Tracetree performs fast ego-centered measurements of the IP topology around a monitor (similar to a routing tree from this node) with low and balanced network load. The tracetree tool discovers a tree by sending probes towards all destinations in parallel in a backward manner and avoids redundancy by stopping probing towards some destinations when paths collapse: given a set of destinations, it first discovers the last link on the path to each of them, then the previous link on each of these paths, and so on; when two (or more) paths reach the same node then it stops probing towards all corresponding destinations except one. |

| Release | 1.0 |
| Scenario | Measurement of ego-centered views from an IPv4 monitor. Monitoring of a network around a node, study of routing trees, test of models. |

3.3 (distributed) UDP-ping
| Description | UDP-ping sends a UDP probe to a given target (IP address) which induces an ICMP message back from this target. In principle, the source address of this answer is the interface used to send it, and so UDP-ping may be used to find a new interface of the target (and for anti-aliasing purpose). In its distributed version, UDP-ping is used to measure the degree of a given router: many monitors distributed in the internet send a probe to a given target and get answers from different interfaces of this target. With many well distributed monitors, one may obtain this way all interfaces of the target (and thus its degree). |
| Licence | open-source (GPLv3) |

| Release | 1.0 |
| Scenario | Network monitoring tool. Listing of interfaces of a target. Estimation of degree distribution. Anti-aliasing. |
