What does IS-IS mean in Networking?
This page is about the meanings of the acronym/abbreviation/shorthand IS-IS in the Computing field in general and in the Networking terminology in particular.
Intermediate System to Intermediate System
IS-IS (also known as ISIS) is an IGP (interior gateway protocol) routing protocol, designed for use within an administrative domain or network. ISIS is a link-state routing protocol which means it reliably floods link state information throughout a network of routers. Each ISIS router independently builds a database of the network's topology using the Dijkstra's algorithm to compute the best path through the network to a destination.

Definition
What does IS-IS mean?
- IS-IS
- Intermediate System to Intermediate System (IS-IS, also written ISIS) is a routing protocol designed to move information efficiently within a computer network, a group of physically connected computers or similar devices. It accomplishes this by determining the best route for data through a packet switching network. The IS-IS protocol is defined in ISO/IEC 10589:2002 as an international standard within the Open Systems Interconnection (OSI) reference design. The Internet Engineering Task Force (IETF) republished IS-IS in RFC 1142, but that RFC was later marked as historic by RFC 7142 because it republished a draft rather than a final version of the (International Organization for Standardization) ISO standard, causing confusion. IS-IS has been called "the de facto standard for large service provider network backbones."
