Routing is the process of selecting a path for traffic in a network or between or across multiple networks.
Internet Routing Registries
There are at least 25 IRRs registering and executing routing policies that
- offer public descriptions of the relationship between external and internal Border Gateway Protocol peers,
- offer Documentation,
- provide routing security,
- allow automatic generation of router configurations,
- provide a debugging aid,
- publish routing intentions,
- construct and maintain routing filters and router configurations, and
- share diagnostic and information service for general network management.[1]
Routing Incidents Types
Border Gateway Protocol (BGP) is a key tool for Internet connection redundancy, enabling data communications between large networks operated by different organizations. However, one bad move can lead to a major blackout.[2] Possible causes could be:
- Misconfiguration
- Malicious
- Targeted Traffic Misdirection
Timeline of Major Incidents
| Date | Incident | Outcomes |
|---|---|---|
| April 25, 1997 | AS 7007 incident among UU/Sprint | |
| May 7, 2005 | Google Outage | |
| February 24, 2008 | Pakistan Telecommunication Authority's attempt to block YouTube access within Pakistan takes down YouTube entirely | |
| November 11, 2008 | The Brazilian ISP Companhia de Telecomunicações do Brasil Central leaked their internal table onto the global BGP table | |
| April 8, 2010 | China Telecom originated 37,000 prefixes not belonging to them in 15 minutes, temporarily causing a global outage | |
| 2011 | Yandex accident | |
| 2014 to 2018 | 3ve’s BGP hijacker schemes |
Routing Security
In June 2022, the SSAC released SAC121, which provides information on:
- The Internet’s routing system,
- routing security challenges for DNS infrastructure operators and their implications,
- the role of network operators in securing the Internet's routing system, and
- security extensions of the border gateway protocol.[3]
