Overview:	J.A.S.P.V.I.(Java Autonomous System Path Visualization Interface) is tool that will help you to see internet Autonomous System connections. It enables you to view current internet (bgp4) connections, browse your neighbour BGP connections, predict 'what if' scenarios, show you multiple networks, and traceroute as-path, for both IPv4 and IPv6.
Access:	No longer available.

Overview:	GASP (Graphical Autonomous System Path) generates a logical map showing the AS path from multiple AS located in Europe and Northern America to a specific network with geographical details. This tool can be used for detection of missing/bogus routes, transition on non-transit links, approximation of the distance and latency to next AS. The output is shown as realtime generated webpage with comprehensive path mapping.

Overview:	Traffic Explorer combines two previously distinct management technologies - route analytics and traffic analysis - to deliver an integrated, real-time view of network-wide routing and traffic behavior.

Overview:	Ally (the Alias Resolver) is used to determine whether two IP addresses belong to interfaces on the same router. By sending UDP datagrams to each address and collecting the responses, Ally outputs and prints the IP identifiers, source IP addresses and remaining TTLs. It then resolves aliases by using heuristics to match these discovered addresses.

Overview:	Iffinder is capable of finding interfaces that belong to the same router. It sends a single UDP packet probe to an unused port on each interface address. Many routers will reply to such a packet with an ICMP PORT UNREACHABLE error. Probing one interface and getting this error from a different interface therefore proves that the two interfaces belong to the same network node.

Contact:	info @ caida.org
Overview:	Like its predecessor skitter, scamper is a tool that actively probes the Internet in order to analyze topology and performance. Unlike skitter, scamper supports both IPv6 and IPv4 path probing. It can also discover the maximum transmission unit (MTU) of a given path. Eventual deployment of scamper monitors will extend CAIDA's Macroscopic Topology Project to cover the growing IPv6 topology.
Access:	Available only to CAIDA members. Data is available to researchers by request.

Contact:	info @ caida.org
Overview:	Otter is used for visualizing arbitrary network data expressed as a set of nodes, links, or paths. Otter has been used to visualize multicast and unicast topology datases, core BGP routing tables, reachability and delay measurements, SNMP data, and website directory structures. Otter's strength lies in its data independence: it can handle any formatted data set consisting of links, nodes, or paths.
