 |  |  |  |  AS Ranking by Cooperative Association for Internet Data Analysis (CAIDA)
This CGI script presents CAIDA's ranking of Autonomous Systems (AS) based on the size of their customer cone as observed from the largest publicly available interdomain routing data set. Ranking relies upon AS relationship information that is discovered using a new inference algorithms. This algorithm is rooted in economic AS relationships, ranking each AS as a function of the number of IP prefixes advertised by this AS, its customer ASes, their customers ASs, and so on. Online, web-based tool.

| | | | aggregate by Joe Abley
aggregate takes a list of prefixes in conventional format on stdin, and performs two optimisations to reduce the length of the prefix list. It removes any supplied prefixes which are supurfluous because they are already included in another supplied prefix (e.g., 203.97.2.0/24 would be removed if 203.97.0.0/17 was also supplied), and identifies adjacent prefixes that can be combined under a single, shorter-length prefix (e.g., 203.97.2.0/24 and 203.97.3.0/24 can be combined into the single prefix 203.97.2.0/23). Manpage: aggregate(1). Operating System: Unix/Linux/POSIX.

| | | | BENTO: BGP-Enabled Network Traffic Organizer by Network Signature
BENTO allows you to explore your traffic based on Autonomous System and BGP path information. Rather than producing graphs of traffic based on router interfaces in your network, BENTO produces graphs of traffic based on AS information. In effect, you can see beyond the border routers of your network, and identify how much traffic you exchange with other networks both near and far away. BENTO lends itself equally well to both real time monitoring of active traffic and to longer term planning for network optimisation. In a real time operational situation, it is easy to configure the BENTO interface to eg pick up and highlight large amounts of ICMP traffic, which would indicate a malfunction or DoS attack. For network planning, BENTO allows you to explore the entire AS spectrum beyond peers and transit providers, and identify interesting hot spots and networks elsewhere. A typical situation would be that you're wondering if it might be worthwhile connecting directly to another exchange. BENTO enables you to see how much traffic you could exchange with the networks present at that exchange. Operating System: Currently BENTO is available for Linux/Intel architectures, and a BSD port is planned. Principally BENTO requires little else than a POSIX compatible system, and should port easily to other systems. At this time, however, such porting would be by specific customer request and agreement.

| | | | BGP++ Simulation Tool by Maniacs Research Group at Georgia Tech
BGP++ is a C++ implementation of BGP for ns-2. BGP++ was not developed from scratch, but existing software (Zebra bgpd) was modified to work with the simulator. Zebra is an open source imlementation of BGP as well as other routing protocols for UNIX platforms. BGP++ tries to maintain most of the Zebra bgpd functionality while it incorporates the software in a OO simulation enviroment. The advantage of this approach is that it saves development effort since the same algorithms are not rewritten and it builds on tested code. Written in C++.

| | | | BGP Monitor by Massachusetts Institute of Technology
The BGP Monitor allows network operators and researchers to look at BGP update traffic history to learn more about network faults. The BGP monitor receives a BGP update feed from MIT's border router; thus, we only learn about changes to choices in best routes to a particular prefix. The monitor supports both live and historical queries. Data is archived into the database every 30 minutes. The monitor can output traffic in text and graph formats. Online, web-based search facility.

| | | | BGP Monitoring System (BGPmon) by Netsec Group, Colorado State University
Real BGP routing information is an essential resource for both researchers and operation communities in Internet routing. In order to collect large number of data in real time, BGP Monitoring System (BGPmon) is designed to monitor BGP updates and routing tables from BGP routers. It uses modular architecture to scalably monitor many BGP routers by distributed deployment while allowing a consolidated and neat interface to end users. BGPmon uses the Extensible Markup Language (XML) for BGP data. This format can accurately record BGP data without any information loss and it is extendable for possible new features in BGP updates. Note: During beta, downloads of BGPmon are password protected. Login info can be obtained by contacting the developers.

| | | | BGP Origins by BGP Origins Project
One very real threat that faces the Internet today is BGP prefix hijacking. Any malicious (or misconfigured) Autonomous System (AS) can announce that it owns any prefixes (ranges of IP addresses). Through announcing this, any number of Internet Service Providers (ISPs) may begin to send traffic to, potentially, malicious routers on the Internet. Automatically mapping BGP prefixes to the ASes that are authorized to announce them is challenging. It is not always straight forward to know who is authorized to announce a prefix. Allowing operational autonomy and freedom complicates structured approaches. BGP-Origins fuses global prefix monitoring data from PHAS and user attestations in a rigorous framework to enable operational entities to view current BGP prefix mappings and to use their own policies/decision making to determine the validity of origin mappings. BGP-Origins uses the DNS protocol as both a look-up and update mechanism. Users can easily query for the mappings of a prefix by issuing a familiar DNS query. Online Service.

| | | | BGPath by Luca Cittadini et al, Roma Tre University
BGPath is an on-line service that helps understanding BGP updates. The service relies on BGP RIB dumps and updates collected by the Routing Information Service and the Route Views Project in the week from 12/26/2006 to 01/02/2007. BGPath features a stream-based back-end system, which: 1. Collects data from many monitors, 2. Performs data cleaning processes that cope with both long-lasting unreliabilities of data sources and short-lived dirty data bursts, 3. Computes metrics over input data within strict time constraints. BGPath also provides a user with an effective graphical interface that, given a routing change c: * Places the ASes involved in c according to the customer-provider hierarchy of the ISPs, * Visualizes both aggregated and disaggregated information for each interdomain link appearing in c, * Traces different paths to the prefix involved in c over time. The service is integrated with software imported from the graphical interface of BGPlay. As an additional function, BGPath also allows to perform comparisons of observed routing data against routing policies stored inside the Internet Routing Registry. The displayed registry information is retrieved and processed by the same engine used in the RPSL Analysis Service. Online, web-based search tool.

| | | | bgpsimple by Christian Zeng
Simple BGP peering and route injection script. This perl script allows to setup an BGP adjacency with a BGP peer, monitor the messages and updates received from that peer, and to send out updates from a predefined set of NLRIs/attributes. BGP session and message handling is done by Net::BGP. The script was mainly written to take a file with BGP route information (TABLE_DUMP_V2 format) and to inject these routes over a BGP adjacency. It grew a little over the time, and has some additional features to tweak and filter those routes before advertising them to the peer. UPDATE messages received will be logged. Currently, there is no implementation of any local routing policy (except the features and sanity checks described at the NOTES section). Furthermore, no adj-rib-in and adj-rib-out databases are maintained. Please note that you might need to patch Net::BGP to get correct handling of AGGREGATOR attributes (see the end of this file), this got fixed in Net::BGP version 0.12. Operating System: Unix/Linux/POSIX (scripts written in Perl).

| | | | C-BGP by University of Louvain-la-Neuve
C-BGP is an efficient BGP decision process simulator. The BGP model implemented in C-BGP is not hindered by the transmission of BGP messages on simulated TCP connections as in SSFNet or JavaSim. The simulator supports the complete BGP decision process, import and export filters and redistribution communities. It is easily configurable through a CISCO-like command-line interface. C-BGP does not model session establishment and timers (MRAI, dampening, etc.). C-BGP can be used to experiment with modified decision processes and additional BGP attributes. It can also be used to evaluate the impact of input/output policies on the routing tables of other ASes. Thanks to its efficiency, it can be used with large topologies with sizes of the same order of magnitude than the Internet. C-BGP is open source and written in C language. It has been tested on various platforms like Linux, FreeBSD and Solaris. To make large simulations easier to perform, C-BGP is able to load interdomain topologies produced by University of Berkeley and is also able to output all the exchanged BGP messages in MRT format so that existing analysis scripts may be re-used. Operating System: Unix/Linux/FreeBSD/Solaris/POSIX.

| | | | Flamingo: Visualizing Internet Traffic by Merit Network, Inc.
Flamingo is a unique software tool that enables Internet traffic data exploration in real-time. Alongwith 3-dimensional data representations, it also provides the necessary navigation and filtering controls to allow users to manipulate the visual displays. Flamingo is composed of two parts, the client and the server. The Flamingo server receives netflow feeds from various routers. This netflow data is then processed, before it is transmitted to the client for visualization. A single Flamingo server can support multiple netflow feeds as well as multiple Flamingo visualization clients. Each client can select to explore different types of data from the same server. Flamingo relies on a set of visualizations to represent complex network data instead of a single representation. The visualizations currently supported are: * Traffic Volume by IP Address or Prefix : In this visualization method we display the volume of traffic being originated from or sent to an IP address or prefix. * Traffic Volume by Peer AS: This visualization method displays the volume of traffic being originated from or sent to various routing peers of the router from which the netflow data is being generated. * Source/Destination Port Traffic: In this visualization we display per port information for each IP address or prefix. * Source IP - Destination IP Traffic Flows: In this visualization we graphically represent individual flows as observed at the sampling router. This shows the relative volume of traffic from various source IP addresses or prefixes to various destinations. * Source IP,Port - Destination IP,Port Traffic Flows: In this comprehensive visualization method we represent in a single display, traffic flows from various source IP addresses/prefixes and source ports to various destination IP addresses and ports. Operating System: Linux.

| | | | Hubble: Monitoring Internet Reachability in Real-Time by University of Washington
Hubble is a system that operates continuously to find persistent Internet black holes as they occur. Hubble has operated continuously since September 17, 2007. During that time, it identified 882,875 black holes and reachability problems. Hubble uses PlanetLab vantage points to monitor prefixes around the world. For each black hole, the table gives the prefix, the origin AS (the ISP owning the prefix), the country, the percentage of Hubble vantage points able to reach the prefix in the last quarter-hourly set of probes, and the duration of the problem so far. The map adjoining the table shows the locations of those prefixes that we are able to geographically map using iPlane or MaxMind GeoLite City. Clicking a link in the table or a marker on the map brings up information on the black hole, including a link to a map showing which vantage points can and cannot reach the prefix. The darker the shadow below a marker, the more problem prefixes in that city. Zooming in on the map will allow you to choose between them. Online, web-based search tool.

| | | | PGBGP: Pretty Good BGP by Josh Karlin, Stephanie Forrest, Jennifer Rexford
PGBGP is a distributed security mechanism for BGP that attempts to avoid prefix hijacks, sub-prefix hijacks, and spoofed paths. Each router individually computes its own idea of the origin ASes for each prefix based on the past few days of routing announcements. Routes for prefixes with new origin ASes are labeled as anomalous and are depreferenced for 24 hours, using the more trusted (stable) routes where possible. New links are also considered anomalous, as well as new sub-prefixes. New sub-prefixes are dealt with by choosing paths to the trusted less specific when possible for 24 hours. Opt-in emails are sent to operators to inform them of anomalies, to help them identify and fix the problem (if any) within the 24 hours. Running PGBGP requires roughly ~20MB of extra RAM. Adding additional BGP sessions does not significantly affect PGBGP memory requirements. CPU requirements are minimal. The reference implementation of PGBGP is developed for Quagga.

| | | | RIS: Routing Information Service by RIPE NCC
The Routing Information Service (RIS) provides information about BGP routing much like "Looking Glass" services offered elsewhere on the Internet. However, the RIS is much more than a conventional "Looking Glass", because it can provide historical information about Internet routing without being bound to the perspective of a particular autonomous system. The service collects routing information by using Remote Route Collectors at different locations around the world and integrates this information into a comprehensive view. The project has a lot of different tools for querying the RIS Database. Online, web-based search facility.

| | | | Route Explorer by Packet Design, Inc.
Packet Design's Route Explorer, an IP routing (Layer 3) visualization, diagnostic and analysis appliance, enables network engineers to easily verify, monitor and optimize network operations, as well as detect, diagnose and resolve IP network problems faster than has been possible till now. Route Explorer works by passively monitoring the routing protocol exchanges (e.g. OSPF, EIGRP, IS-IS, BGP) between all routers on the network, then computing and displaying a routing topology map. This map is updated whenever the routing topology changes, providing the most accurate, real-time view of how the network is directing traffic. Unstable routes and other anomalies - undetectable by SNMP-based management tools because they are not device-specific problems - are immediately visible. Operating System: Dedicated Appliance.

| | | | RPSL Analysis Service by Giuseppe Di Battista, Tiziana Refice, Massimo Rimondini
The IRR is a unique and significant source of information to understand the Internet routing. However, since registries are maintained on a voluntary basis, information contained inside them may be inconsistent or outdated. Moreover, routing policies can be expressed in RPSL by using complex constructions, and the level of accuracy of the descriptions may vary. All these factors make the task of automatically extracting useful information from the IRR a difficult one. This service was designed to automatically extract peering information from the IRR. The service generates reports about the contents of the registries and provides a list of peering candidates extracted from RPSL data. Online tool.

| | | | TOTEM Project by S. Balon, O. Delcourt, J. Lepropre, G. Monfort, F. Skivee
The objective of the TOTEM project (TOolbox for Traffic Engineering Methods) is to develop a toolbox of algorithms for traffic engineering purposes. The project will generic algorithms for the optimization of networks of big size which will apply, on one hand, to IP networks, and on the other hand, to networks operated with (G)MPLS. Some of these algorithms will require extensions to the routing (OSPF-TE, ISIS-TE, BGP) or signalling (RSVP-TE) protocols which will be submitted to IETF. This toolbox will be available in open source and will be designed such that its elements can easily be integrated in various platforms such as Linux PCs, routers, and open source network simulators like NS and/or J-Sim. TOTEM depends on the following libraries: Brite, catalina-ant, C-BGP, Jakarta Commons Java Collections Framework, Colt, epsgraphics, Javac2, jax-qname, JAXB, JCommmon, JFreeChart, JGraphT, Jung, JUnit, Log4J, relaxngDataType, xsdlib and mt19937ar (used by IGPWO).

| | | | XORP Open Source IP Router by Xorp.org
XORP is an open router platform being developed at the ICSI Center for Open Networking (ICON) at the International Computer Science Institute in Berkeley, California, USA. XORP primary goal is to be both a research tool and a stable deployment platform that can be used to close the gap between network research and real world. XORP design philosophy is: * modularity. * extensibility. * performance. * robustness. This is achieved by carefully separating functionalities into independent modules, and by providing an API for each module. XORP divides into two subsystems. The higher-level ("user-level") subsystem consists of the routing protocols. The lower-level ("kernel") manages the forwarding path, and provides APIs for the higher-level to access. Operating System: FreeBSD/Linux. Also available as Live CD.
