Border Gateway Protocol

BGP (English Border Gateway Protocol, Border Gateway Protocol) - the basic dynamic routing protocol on the Internet.

BGP, in contrast to other dynamic routing protocols used to exchange routing information between different routers do not, but between the entire autonomous system, and therefore, in addition to information on routes in the network also carries information about the routes to the autonomous system. BGP does not use technical metrics, and selects the best route based on the rules adopted in the network.

BGP supports classless addressing and uses route summarization to reduce the routing tables. Since 1994, the fourth version of the protocol, all previous versions are obsolete.

BGP is the application protocol and operates over the transport protocol TCP (port 179).

BGP, along with DNS, is one of the main mechanisms for the functioning of the Internet.

BGP is the result of a collaboration between Los Angeles and Colorado State University and the University of Oregon.

Main news of the project
Toolset Link Rank successful launch publicly
LinkRank tool used to visualize and diagnose BGP routing dynamics was released in December 2004. Please vist this page Home LinkRank details and download instructions.

The topology of the Web page Launched
To ensure the research community on the Internet easily accessible topology, we launched a project to collect the topology of the Internet. We use multiple sources of data and store the topology information for a long time to provide the most complete, annotated, up to date <AS-level topology.

Beyond BGP is a collaboration between UCLA, Colorado State University, and University of Oregon.

Topology Web Page Launched
To provide network research community an easily available Internet topology, we launched a project on Internet Topology collection. We use multiple data sources and accumulate topological information over time to provide the most complete, annotated, up-to-date < AS-level topology.
